driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. Fully functional daytime running lamps are required on all vehicles ﬁrst sold in Canada. 216 The DRL system will come on when the following conditions are met: (cid:129) The ignition is on. (cid:129) The exterior lamps control is in AUTO. (cid:129) The transmission is not in PARK (P). (cid:129) The light sensor determines it is daytime. When the DRL are on, only your DRL lamps will be on. The taillamps, sidemarker, and other lamps will not be on. The instrument panel will not be lit up either. When it begins to get dark, the automatic headlamp system will switch from DRL to the headlamps. To turn off the DRL lamps, turn the exterior lamps control to the OFF position and then release. For vehicles ﬁrst sold in Canada, the transaxle must be in the PARK (P) position, before the DRL lamps can be turned off. As with any vehicle, you should turn on the regular headlamp system when you need it. (cid:129) (cid:129) Automatic Headlamp System When it is dark enough outside, the automatic headlamp system will turn on the headlamps at the normal brightness, along with the taillamps, sidemarker, parking lamps, and the instrument panel lights. The radio lights will also be dim. To turn off the automatic headlamp system, turn the exterior lamps switch to the off position and then release. For vehicles ﬁrst sold in Canada, the transaxle must be in the PARK (P) position, before the automatic headlamp system can be turned off. The vehicle has a light sensor located on the top of the instrument panel in the defroster grille that regulates when the automatic headlamps turn on. Be sure it is not covered, or the headlamps will come on whenever the ignition is on. The system may also turn on the headlamps when driving through a parking garage, heavy overcast weather, or a tunnel. This is normal. There is a delay in the transition between the daytime and nighttime operation of the Daytime Running Lamps (DRL) and the automatic headlamp systems so that driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp system will only be affected when the light sensor detects a change in lighting lasting longer than the delay. If you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave the garage, it will take approximately one minute for the automatic headlamp system to change to DRL if it is bright enough outside. During that delay, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness control is in the full bright position. See Instrument Panel Brightness on page 219. Your headlamps will also stay on after you exit the vehicle. You can program this feature using the Driver Information Center (DIC). See DIC Vehicle Customization (With DIC Buttons) on page 280. As with any vehicle, you should turn on the regular headlamp system when needed. 217 Fog Lamps - (Fog Lamps): If your vehicle has fog lamps, the button is located on the instrument panel to the left of the steering column and below the dome lamp override button. The ignition must be in RUN and the parking lamps must be on for the fog lamps to work. To turn the fog lamps on, press the fog lamps button. A light comes on in the instrument panel cluster to let you know that the fog lamps are on. Press the button again to turn the fog lamps off. When the fog lamps are turned on, the low-beam headlamps automatically turn on. The fog lamps turn off while you change to high-beam headlamps. When the high-beam headlamps go off, the fog lamps will come on again. Fog lamps should only be used in foggy conditions since they could be distracting to oncoming drivers in clear weather conditions. Some localities have laws that require the headlamps to be on along with the fog lamps. 218 Auxiliary Roof Mounted Lamp If your vehicle has this feature, this button includes wiring provisions for a dealer or a qualiﬁed service center to install an auxiliary roof lamp. This button is located on the overhead console. When the wiring is connected to an auxiliary roof mounted lamp, pressing the bottom of the button will activate the lamp and illuminate an indicator light at the bottom of this button. Pressing the top of the button will turn off the roof mounted lamp and indicator. The emergency roof lamp circuit is fused at 30 amps, so the total current draw of the attached lamps should be less than this value. The attachment points for the roof lamp circuits are two blunt cut wires located above the overhead console, a dark green switched power wire and a black ground wire. For further information on roof mount emergency lamp installation, please visit the GM Upﬁtter website at www.gmupﬁtters.com or contact your dealer. If your vehicle has this button, your vehicle may have the snow plow prep package. For further information see Adding a Snow Plow or Similar Equipment on page 412. Instrument Panel Brightness D(Instrument Panel Brightness): This feature controls the brightness of the instrument panel lights. The knob for this feature is located next to the headlamp control. Turn the knob clockwise or counterclockwise to adjust the brightness of the instrument panel lights. Turn the knob clockwise to return the instrument panel cluster or radio display to full brightness when the headlamps or parking lamps are on. To turn on the dome lamps, turn the knob to the farthest clockwise position. Dome Lamps The dome lamps come on when a door is opened. The dome lamps can also be turned on by turning the knob, located next to the exterior lamps control, clockwise to the farthest position. In this position, the dome lamps will remain on whether a door is opened or closed. Dome Lamp Override E (Dome Lamp Override): Press the dome override button, located next to the exterior lamps control, to keep the dome lamps off when a door is open. To set the lamps to the automatic operation, press the button again so that it is extended. With the button in this position, the dome lamps will come on when a door is opened. 219 Entry Lighting Your vehicle has an illuminated entry feature. When the doors are opened, the dome lamps will come on if the dome override button is in the extended position. If the dome override button is pressed in, the lamps will not come on. Exit Lighting With exit lighting, the interior lamps will come on when the key is removed from the ignition. They will turn off automatically in 20 seconds. The lights will not come on if the dome override button is pressed in. Reading Lamps If your vehicle has reading lamps they are located on the overhead console. To turn on the reading lamps, press the button located next to each lamp. To turn them off, press the button again. Your vehicle may also have reading lamps in other locations. To turn the lamps on or off, press the button located next to the lamp. The lamps are ﬁxed and cannot be adjusted. Electric Power Management The vehicle has Electric Power Management (EPM) that estimates the battery’s temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery’s state of charge is low, the voltage is raised slightly to quickly put the charge back in. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gage or voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. 220 The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. A high electrical load occurs when several of the following loads are on: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. EPM works to prevent excessive discharge of the battery. It does this by balancing the generator’s output and the vehicle’s electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as Battery Saver Active or Service Battery Charging System. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages on page 270. Battery Run-Down Protection This feature shuts off the dome, and reading lamps if they are left on for more than 10 minutes when the ignition is off. This will keep the battery from running down. 221 Ultrasonic Rear Parking Assist (URPA) If your vehicle has the Ultrasonic Rear Parking Assist (URPA) system it is designed to help you park while in Reverse (R). It operates only at speeds less than 5 mph (8 km/h). URPA helps make parking easier and helps you avoid colliding with objects such as parked vehicles. The URPA system detects objects that are close to the rear of the vehicle which are at least 10 inches (25.4 cm) off the ground and below hood or trunk level. The system detects objects up to 8 feet (2.5 m) behind your vehicle. The URPA sensors determine how close these objects are from your bumper within this area. 222 {CAUTION: The Ultrasonic Rear Park Assist (URPA) system does not replace driver vision. URPA does not: (cid:129) Operate above speeds of 5 mph (8 km/h). (cid:129) Detect objects more than 8 feet (2.5 meters) behind the vehicle. This distance may be less during warmer or humid weather. (cid:129) Detect objects that are below the bumper, underneath the vehicle, or that are very close to the vehicle. (cid:129) Detect children, pedestrians, bicyclists, or pets. So if you do not use proper care before backing up, you could hit a vehicle, child, pedestrian, bicyclist, or pet, resulting in vehicle damage, injury, or death. Even though the vehicle has the URPA system, always check carefully before backing up by checking behind your vehicle. The URPA display is located near the passenger side rear window and can be seen by looking over your right shoulder. The URPA display has three color-coded lights. The lights are used to provide distance and system information, along with beeps that will be heard through the speakers. URPA can be turned off by pressing the rear park aid disable button located next to the radio. The indicator light will come on to indicate that URPA is off. The red light in the URPA display will also be lit if the vehicle is in REVERSE (R). If the vehicle has a Driver Information Center (DIC), PARKING ASSIST OFF will display on the screen. URPA automatically turns back on each time the vehicle is started. How the System Works When the shift lever is moved into REVERSE (R), the rear display will brieﬂy come on to let you know the display is operating correctly. URPA comes on automatically when the shift lever is moved into REVERSE (R). The system does not work at a reverse speed greater than 5 mph (8 km/h). To remind you of this, the red light on the rear display will ﬂash. 223 How the System Works when Backing If the shift lever is in REVERSE (R), URPA detects objects close to the rear bumper. The ﬁrst time an object is detected a single beep will sound. If an object is detected at a REVERSE (R) speed between 0 mph (0 km/h) and 5 mph (8 km/h), the following describes what will occur based on your distance to a detected object located behind the vehicle: (cid:129) At distances between 40 inches (1 m) and 8 ft (2.5 m), a single amber light will come on. (cid:129) At distances between 23 inches (0.6 m) and 40 inches (1 m), both amber lights will be on. (cid:129) At distances between 12 inches (0.3 m) and 23 inches (0.6 m), all three lights (amber/ amber/red) will be on. (cid:129) At distances less than 12 inches (0.3 m), a beeping sound will repeat for a short time and all three lights (amber/amber/red) will ﬂash. 224 When the System Does Not Seem to Work Properly If the URPA system will not activate due to a temporary condition, the message PARKING ASSIST OFF will be displayed on the DIC screen and a red light will come on the URPA display when the shift lever is moved into REVERSE (R). This occurs under the following conditions: (cid:129) The driver disables the system. (cid:129) The parking brake pedal is depressed. (cid:129) A trailer was attached to your vehicle, or a bicycle or an object was hanging out of your trunk during your last drive when you turned off the vehicle. If the attached objects are removed from your vehicle before the start of your next drive, the system will return to normal operation unless an object is detected when the vehicle is shifted into REVERSE (R). If this occurs, URPA assumes the object is still attached, so you will have to wait until the vehicle is driven forward above 15 mph (25 km/h) before URPA will return to normal operation. (cid:129) The ultrasonic sensors are not kept clean. So, be sure to keep your vehicle’s rear bumper free of mud, dirt, snow, ice, and slush. For cleaning instructions, see Washing Your Vehicle on page 557. If the DIC still displays the PARKING ASSIST OFF message after cleaning the bumper and driving forward at a speed of at least 15 mph (25 km/h), see your dealer. (cid:129) Other conditions that may affect system performance include vibrations from a jackhammer or the compression of air brakes on a very large truck or other mechanical devices that interfere with URPA performance. (cid:129) When URPA is disabled without driver action and the driver attempts to turn URPA back on by pressing the rear park aid button, the indicator light will ﬂash for 3 seconds and then stay lit to indicate that URPA is off. As always, drivers should use care when backing up a vehicle. Always look behind you, being sure to check for other vehicles, obstructions and blind spots. For Driver Information Center messages related to URPA, see DIC Warnings and Messages on page 270. If the vehicle bumper is damaged, the URPA system may not work properly. Take the vehicle to your dealer to repair the system. Accessory Power Outlet(s) Accessory power outlets can be used to connect auxiliary electrical equipment, such as a cellular telephone or CB radio. The outlet can accept electrical equipment up to a maximum of 20 amperes. There are four accessory power outlets. There are two under the climate controls, one on the back of the ﬂoor console and a additional accessory power outlet in the rear cargo area on the passenger side. 225 If electrical devices are left plugged To use the power outlet, lift the spring cap and insert electrical 12V device plug. To close the power outlet, remove 12V electrical device plug and the spring cap will close. The accessory power outlets are powered, even with the ignition off. Continuing to use power outlets while the ignition is off may cause the vehicle’s battery to run down. Notice: into a power outlet, the battery may drain causing your vehicle not to start or damage to the battery. This would not be covered by the warranty. Always unplug all electrical devices when turning off your vehicle. Certain power accessory plugs may not be compatible to the accessory power outlet and could result in blown adapter or vehicle fuses. If you experience a problem, see your dealer for additional information on the accessory power plugs. Notice: Adding any electrical equipment to your vehicle may damage it or keep other components from working as they should. The repairs would not be covered by your warranty. Do not use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer/retailer before adding electrical equipment. When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment. Do not use equipment exceeding the maximum amperage rating of 20 amperes. Notice: Improper use of the power outlet can cause damage not covered by your warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only. 226 If you put papers, pins, or other Ashtray(s) and Cigarette Lighter The front ashtray is located near the center of the instrument panel or on the front console, if equipped. Pull on the ashtray door to open it. Notice: ﬂammable items in the ashtray, hot cigarettes or other smoking materials could ignite them and possibly damage your vehicle. Never put ﬂammable items in the ashtray. To remove the front ashtray pull the ashtray up. To use the cigarette lighter, push it in all the way, and let go. When it’s ready, it will pop back out by itself. Notice: Holding a cigarette lighter in while it is heating does not let the lighter back away from the heating element when it is hot. Damage from overheating can occur to the lighter or heating element, or a fuse could be blown. Do not hold a cigarette lighter in while it is heating. Climate Controls Climate Control System With this system you can control the heating, cooling, defrost, defog and ventilation of your vehicle. Manual Operation Turn the right knob clockwise or counterclockwise to direct the airﬂow inside of your vehicle. 227 To change the current mode, select one of the following: H (Vent): This mode directs air to the instrument panel outlets. ) (Bi-Level): This mode directs half of the air to the instrument panel outlets and to the ﬂoor outlets. The ﬂow can be divided between vent and ﬂoor outlets depending upon where the knob is placed between the settings. A little air is directed towards the windshield and side window outlets. Cooler air is directed to the upper outlets and warmer air to the ﬂoor outlets. 6 (Floor): This mode directs most of the air to the ﬂoor outlets, with some of the air directed to the windshield, side window outlets, and second row ﬂoor outlets. In this mode, the system will automatically select outside air. Recirculation cannot be selected when in Floor Mode. The right knob can also be used to select defog or defrost mode. For more information, see “Defogging and Defrosting” later in this section. By positioning the right knob between two modes, a combination of those two modes is selected. The air conditioning compressor will be on unless the outside temperature is close to freezing. 9 (Fan): Turn the left knob clockwise or counterclockwise to increase or decrease the fan speed. Turn the knob all the way counterclockwise to turn the front system off. ? (Recirculation): Press this button to turn the recirculation mode on. When the button is pressed, an indicator light will come on. This mode keeps outside air from entering the vehicle. It can be used to reduce outside air and prevent odors from entering your vehicle. Recirculation may also help cool the air inside your vehicle more quickly once the temperature inside the vehicle is less than the outside temperature. 228 The recirculation mode cannot be used with ﬂoor, defrost, or defogging modes. If you try to select recirculation in one of those modes, the indicator will ﬂash three times and turn off. The air conditioning compressor will also come on when this mode is activated. While in recirculation mode the windows may fog when the weather is cold and damp. To clear the fog, select either the defog or defrost mode and increase the fan speed. Recirculation mode can be turned off by pressing the button again, or turning off the engine. AUX (Auxiliary): Pressing this button will turn the rear heating and air conditioning on. See Rear Air Conditioning and Heating System on page 239 or Rear Air Conditioning and Heating System and Electronic Climate Controls on page 240 for more information. Temperature Control: Rotate the thumbwheels up or down to increase or decrease the temperature on the driver’s side or the passenger side of the vehicle for the dual zone system. # (Air Conditioning): Press this button on the left knob to turn the air conditioning system on or off. When A/C is pressed, an indicator light will come on to let you know that the air conditioning has been activated. On hot days, open the windows to let hot inside air escape; then close them. This helps to reduce the time it takes for your vehicle to cool down. It also helps the system to operate more efficiently. The air conditioning system removes moisture from the air, so you may sometimes notice a small amount of water dripping underneath your vehicle while idling or after turning off the engine. This is normal. Defogging and Defrosting Fog on the inside of the windows is a result of high humidity (moisture) condensing on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to clear fog or frost from your windshield. Turn the right knob clockwise to select the defog or defrost mode. 229 - (Defog): The defog mode is used to clear the windows of fog or moisture and warm the passengers. This mode directs air to the windshield, ﬂoor outlets, and side window vents. When you select this mode, the system turns off recirculation and runs the air conditioning compressor unless the outside temperature is close to freezing. The recirculation mode cannot be selected while in the defog mode. Do not drive the vehicle until all the windows are clear. 0 (Defrost): The defrost mode is used to remove fog or frost from the windshield more quickly. This mode directs a portion of the air to the windshield and side window vents and some to the ﬂoor vents. In this mode, the system will automatically force outside air into your vehicle. The recirculation mode cannot be selected while in the defrost mode. The air conditioning compressor will run automatically in this setting, unless the outside temperature is close to freezing. Do not drive the vehicle until all the windows are clear. Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. < (Rear Window Defogger): Press this button on the right knob to turn on the rear window defogger. The system will automatically turn off several minutes after it has been activated. The defogger can also be turned off by pressing the button again or by turning off the engine. Do not drive the vehicle until all the windows are clear. If your vehicle has heated outside rearview mirrors, the mirrors will heat to help clear fog or frost from the surface of the mirror when the rear window defog button is pressed. Notice: Do not use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs would not be covered by your warranty. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid. 230 Dual Automatic Climate Control System With this system, you can control the heating, cooling, and ventilation in your vehicle. Your vehicle also has a ﬂow-through ventilation system described later in this section. Driver’s Side Temperature Control The driver’s side temperature buttons are used to adjust the temperature of the air coming through the system on the driver’s side. The temperature can be adjusted even if the system is turned off. This is possible since outside air will always ﬂow through the system as the vehicle is moving forward unless it is set to recirculation mode. See “Recirculation” later in this section. Press the + or − buttons to increase or decrease the cabin temperature. The driver side temperature display will show the temperature setting decreasing or increasing. You can select different climate control settings for the driver and passengers. 231 Passenger’s Side Temperature Control The passenger’s temperature buttons can be used to change the temperature of the air coming through the system on the passenger’s side of the vehicle. The temperature can be adjusted even if the system is turned off. This is possible since outside air will always ﬂow through the system as the vehicle is moving forward unless it is set to recirculation mode. See “Recirculation” later in this section. Press the + or − buttons to increase or decrease the cabin temperature. The passenger side display will show the temperature setting decreasing or increasing. The passenger’s temperature setting can be set to match the driver’s temperature setting by pressing the PASS button and turning off the PASS indicator. When the passenger’s temperature setting is set different than the driver’s setting, the indicator on the PASS button will illuminate and both the driver’s side and passenger’s side temperature displays will be shown. Automatic Operation AUTO (Automatic): When automatic operation is active the system will control the inside temperature, the air delivery, and the fan speed. Use the steps below to place the entire system in automatic mode: 1. Press the AUTO button. When AUTO is selected, the display will change to show the current temperature(s) and AUTO will be lit on the display. The current delivery mode and fan speed will also be displayed for approximately 5 seconds. When AUTO is selected, the air conditioning operation and air inlet will be automatically controlled. The air conditioning compressor will run when the outside temperature is over about 40°F (4°C). The air inlet will normally be set to outside air. If it is hot outside, the air inlet may automatically switch to recirculate inside air to help quickly cool down your vehicle. The light on the button will illuminate in recirculation. 232 2. Set the driver’s and passenger’s temperature. To ﬁnd your comfort setting, start with a 74°F (23°C) temperature setting and allow about 20 minutes for the system to regulate. Use the driver’s or passenger’s temperature buttons to adjust the temperature setting as necessary. If you choose the temperature setting of 60°F (15°C), the system will remain at the maximum cooling setting. If you choose the temperature setting of 90°F (32°C), the system will remain at the maximum heat setting. Choosing either maximum setting will not cause the vehicle to heat or cool any faster. Be careful not to cover the solar sensor located on the top of the instrument panel near the windshield. This sensor regulates air temperature based on sun load and also turns on your headlamps. For more information on the solar sensor, see “Sensors” later in this section. To avoid blowing cold air in cold weather, the system will delay turning on the fan until warm air is available. The length of delay depends on the engine coolant temperature. Pressing the fan switch will override this delay and change the fan to a selected speed. O (On/Off): Press this button to turn off the climate control system. Outside air will still enter the vehicle, and will be directed to the ﬂoor. This direction can be changed by pressing the mode button. Recirculation can be selected once you have selected vent or bi-level mode. The temperature can also be adjusted using either temperature button. If you adjust the air delivery mode or temperature settings with the system off, the display will illuminate brieﬂy to show you the settings and then return off. Press the on/off button or the up down arrows on the fan switch, the defrost button, AUTO button, or the air conditioning button to turn the system on when it is off. 233 Manual Operation You may manually adjust the air delivery mode or fan speed. y9 z (Fan): The buttons with the fan symbols allow you to manually adjust the fan speed. Press the up arrow to increase fan speed and the down arrow to decrease fan speed. Pressing one of these buttons when the system is off will turn the system on. Pressing one of these buttons when in automatic control will place the fan under manual control. The fan setting will remain displayed and the AUTO light will turn off. The air delivery mode will remain under automatic control. yN z (Mode): Press the mode up and down buttons to manually change the direction of the airﬂow in your vehicle. Repeatedly press the button until the desired mode appears on the display. Pressing one of these buttons when the system is off will change air delivery mode without turning the system on. Pressing one of these buttons when in automatic control will place the mode under manual control. 234 The air delivery mode setting will be displayed and the AUTO light will turn off. The fan will remain under automatic control. H (Vent): This setting will deliver air to the instrument panel outlets. ) (Bi-Level): This mode directs half of the air to the instrument panel outlets and half to the ﬂoor outlets. The ﬂow can be divided between vent and ﬂoor outlets depending upon where the knob is placed between the settings. A little air is directed towards the windshield and side window outlets. Cooler air is directed to the upper outlets and warmer air to the ﬂoor outlets. 6 (Floor): This mode directs most of the air to the ﬂoor outlets, with some of the air directed to the windshield, side window outlets, and second row ﬂoor outlets. In this mode, the system will automatically select outside air. - (Defog): See “Defogging and Defrosting” later in this section. @ (Recirculation): Press this button to turn the recirculation mode on. When the button is pressed, an indicator light will come on. This mode keeps outside air from entering the vehicle. It can be used to reduce outside air and prevent odors from entering your vehicle. Recirculation may also help cool the air inside your vehicle more quickly once the temperature inside the vehicle is less than the outside temperature. The recirculation mode cannot be used with ﬂoor, defrost, or defogging modes. If you try to select recirculation in one of those modes, the indicator will ﬂash three times and turn off. The air conditioning compressor will also come on when this mode is activated. While in recirculation mode the windows may fog when the weather is cold and damp. To clear the fog, select either the defog or defrost mode and increase the fan speed. Recirculation mode can be turned off by pressing the button again, or turning off the engine. Air Conditioning # (Air Conditioning): Press this button to turn the air conditioning (A/C) compressor on and off. When air conditioning is selected, an indicator light will come on to let you know that the air conditioning has been activated. Pressing this button when the outside temperature is too cool for air conditioning will make the air conditioning indicator ﬂash three times and then turn off to let you know the air conditioning mode is not available. If the air conditioning is on and the outside temperature drops below a temperature which is too cool for air conditioning to be effective, the air conditioning light will turn off to show that the air conditioning mode has been canceled. On hot days, open the windows long enough to let hot inside air escape. This helps to reduce the time it takes for your vehicle to cool down. It also helps the system to operate more efficiently. The air conditioning system removes moisture from the air, so you may sometimes notice a small amount of water dripping underneath your vehicle while idling or after turning off the engine. This is normal. 235 Sensors The solar sensor, located in the defrost grille in the middle of the instrument panel, monitors the solar radiation. Do not cover the solar sensor or the system will not work properly. The interior temperature sensors located in the headliner above the driver side seat and in the headliner above the second row seats measure the temperature of the air inside your vehicle. There is also an exterior temperature sensor located behind the front grille. This sensor reads the outside air temperature and helps maintain the temperature inside the vehicle. Any cover on the front of the vehicle could cause a false reading in the displayed temperature. 236 The climate control system uses the information from these sensors to maintain your comfort setting by adjusting the outlet temperature, fan speed, and the air delivery mode. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be used as needed to maintain cool outlet temperatures. Defogging and Defrosting Fog on the inside of the windows is a result of high humidity (moisture) condensing on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to clear fog or frost from your windshield. Use the mode up and down arrows to select the defog or defrost modes. - (Defog): The defog mode is used to clear the windows of fog or moisture and warm the passengers. This mode directs air to the windshield, ﬂoor outlets, and side window vents. When you select this mode, the system turns off recirculation and runs the air conditioning compressor unless the outside temperature is close to freezing. The recirculation mode cannot be selected while in the defog mode. Do not drive the vehicle until all the windows are clear. 0 (Defrost): Press this button to remove fog or frost from the windshield more quickly. This mode directs a portion of the air to the windshield and side window vents and some to the ﬂoor vents. In this mode, the system will automatically force outside air into your vehicle. The recirculation mode cannot be selected while in the defrost mode. The air conditioning compressor will run automatically in this setting, unless the outside temperature is close to freezing. Do not drive the vehicle until all the windows are clear. Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. < (Rear Window Defogger): Press this button to turn on the rear window defogger. It will automatically turn off several minutes after it has been activated. The defogger can also be turned off by pressing the button again or by turning off the engine. Do not drive the vehicle until all the windows are clear. 237 If your vehicle has heated outside rearview mirrors, the mirrors will heat to help clear fog or frost from the surface of the mirror when the rear window defog button is pressed. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty. Outlet Adjustment Use the air outlets located in the center and on the side of your instrument panel to direct the airﬂow. Operation Tips (cid:129) Keep the hood and front air inlets free of ice, snow, or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows. (cid:129) When you enter a vehicle in cold weather, press the fan up button to the maximum fan level before driving. This helps clear the intake ducts of snow and moisture, and reduces the chance of fogging the inside of your window. (cid:129) Keep the air path under the front seats clear of objects. This helps air to circulate throughout your vehicle. (cid:129) Adding outside equipment to the front of your vehicle, such as hood-air deﬂectors, may affect the performance of the heating and air conditioning system. Check with your dealer before adding equipment to the outside of your vehicle. 238 Rear Air Conditioning and Heating System If your vehicle has this system, the rear controls are three knobs located in the headliner. The system can be controlled from the front controls as well as the rear controls. To turn the system on, press the AUX button on the front climate control system, an indicator will be lit. Pressing the AUX button the ﬁrst time will turn the rear system on in a mimic mode. In this mode, the airﬂow in the rear will be approximately the same direction, temperature, and fan speed as the front. Pressing the AUX button again will turn the rear system and the indicator off.

Warning Lights, Gages, and Indicators This part describes the warning lights and gages on your vehicle. The pictures help to locate them. Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to the warning lights and gages could also save you or others from injury. Warning lights come on when there may be or is a problem with one of your vehicle’s functions. As the details show on the next few pages, some warning lights come on brieﬂy when you start the engine just to let you know they are working. If you are familiar with this section, you should not be alarmed when this happens. Gages can indicate when there may be or is a problem with one of your vehicle’s functions. Often gages and warning lights work together to let you know when there is a problem with your vehicle. When one of the warning lights comes on and stays on as you are driving, or when one of the gages shows there may be a problem, check the section that tells you what to do about it. Please follow this manual’s advice. Waiting to do repairs can be costly and even dangerous. So please get to know your vehicle’s warning lights and gages. They can be a big help. Your vehicle also has a Driver Information Center (DIC) that works along with warning lights and gages. See DIC Warnings and Messages on page 270 for more information. 242 Instrument Panel Cluster United States version shown. Canada similar. Your instrument cluster is designed to let you know at a glance how your vehicle is running. You will know how fast you are going, about how much fuel you have and many other things you will need to know to drive safely and economically. 243 Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). Trip Odometer The trip odometer can tell you how far your vehicle has been driven since you last set the trip odometer to zero. Press the reset button, located on the instrument panel cluster next to the trip odometer display, to toggle between the trip odometer and the regular odometer. Holding the reset button for approximately one second while the trip odometer is displayed will reset it. To display the odometer reading with the ignition off, press the reset button. Tachometer Your tachometer displays the engine speed in revolutions per minute (rpm). Safety Belt Reminder Light When the key is turned to RUN or START, a chime will sound for several seconds to remind people to buckle their safety belts. The driver safety belt light will also come on and stay on for several seconds. Then it will ﬂash for several more. You should buckle your seat belt. This chime and light will be repeated if the driver remains unbuckled and the vehicle is in motion. If the driver’s belt is buckled, neither the chime nor the light will come on. See Passenger Sensing System on page 101 for more information. 244 Passenger Safety Belt Reminder Light Several seconds after the key is turned to RUN or START, a chime will sound for several seconds to remind the front passenger to buckle their safety belt. The passenger safety belt light will also come on and stay on for several seconds, then it will ﬂash for several more. This chime and light will be repeated if the passenger remains unbuckled and the vehicle is in motion. Airbag Readiness Light There is an airbag readiness light on the instrument panel, which shows the airbag symbol. The system checks the airbag’s electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the airbag sensors, the airbag modules, the wiring and the crash sensing and diagnostic module. For more information on the airbag system, see Airbag System on page 90. This light will come on when you start your vehicle, and it will ﬂash for a few seconds. If the passenger’s safety belt is buckled, neither the chime nor the light will come on. Then the light should go out. This means the system is ready. 245 {CAUTION: If the airbag readiness light stays on after you start your vehicle, it means the airbag system may not be working properly. The airbags in your vehicle may not inﬂate in a crash, or they could even inﬂate without a crash. To help avoid injury to yourself or others, have your vehicle serviced right away if the airbag readiness light stays on after you start your vehicle. If the airbag readiness light stays on after you start the vehicle or comes on when you are driving, your airbag system may not work properly. Have your vehicle serviced right away. The airbag readiness light should ﬂash for a few seconds when you turn the ignition key to RUN. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. 246 Passenger Airbag Status Indicator Your vehicle has the passenger sensing system. Your overhead console has a passenger airbag status indicator. United States Canada When the ignition key is turned to RUN or START, the passenger airbag status indicator will light ON and OFF, or the symbol for on and off, for several seconds as a system check. Then, after several more seconds, the status indicator will light either ON or OFF, or either the on or off symbol, to let you know the status of the right front passenger’s frontal airbag. If the word ON or the on symbol is lit on the passenger airbag status indicator, it means that the right front passenger’s frontal airbag is enabled (may inﬂate). {CAUTION: {CAUTION: If the on indicator comes on when you have a rear-facing child restraint installed in the right front passenger’s seat, it means that the passenger sensing system has not turned off the passenger’s frontal airbag. A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inﬂates. This is because the back of the rear-facing child restraint would be very close to the inﬂating airbag. Do not use a rear-facing child restraint in the right front passenger’s seat if the airbag is turned on. Your vehicle has a rear seat that will accommodate a rear-facing child restraint. A label on your sun visor says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the airbag deploys. Even though the passenger sensing system is designed to turn off the right front passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is fail-safe, and no one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. We recommend that rear-facing child restraints be secured in the rear seat, even if the airbag is off. If the word OFF or the off symbol is lit on the airbag status indicator, it means that the passenger sensing system has turned off the right front passenger’s frontal airbag. See Passenger Sensing System on page 101 for more on this, including important safety information. 247 If, after several seconds, all status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer for service. {CAUTION: If the off indicator and the airbag readiness light ever come on together, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger seat may not have the protection of the frontal airbag. See Airbag Readiness Light on page 245. 248 Charging System Light The charging system light will come on brieﬂy when you turn on the ignition, but the engine is not running, as a check to show you it is working. It should go out once the engine is running. If it stays on, or comes on while you are driving, you may have a problem with the charging system. It could indicate that you have problems with the generator, the generator drive belt, or another electrical problem. Have it checked right away. Driving while this light is on could drain your battery. When this light comes on, the Driver Information Center (DIC) will also display the SERVICE BATTERY NOT CHARGING SYSTEM message. See DIC Warnings and Messages on page 270 for more information. If you must drive a short distance with the light on, be certain to turn off all your accessories, such as the radio and air conditioner, to reduce the drain on your battery. Voltmeter Gage When your engine is not running, but the ignition is in RUN, this gage shows your battery’s state of charge in DC volts. When the engine is running, the gage shows the condition of the charging system. The charging system regulates voltage based on the state of the battery for improved fuel economy and battery life. The gage may transition from a higher to lower or a lower to higher reading, this is normal. Readings between the low and high warning zones indicate the normal operating range. Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create full power. If there is a problem with the battery charging system, this light will come on or the SERVICE BATTERY CHARGING SYSTEM DIC message will display. See DIC Warnings and Messages on page 270 and Charging System Light on page 248 for more information. Brake System Warning Light With the ignition on, the brake system warning light will come on when you set the parking brake. If you try to drive with the parking brake engaged, a chime will sound when the vehicle speed is greater than 5 mph (8 km/h). Your vehicle’s hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop you. For good braking, though, you need both parts working well. If the warning light comes on and a chime sounds there could be a brake problem. Have your brake system inspected right away. 249 This light may also come on due to low brake ﬂuid. See Brakes on page 486 for more information. {CAUTION: United States Canada This light should come on brieﬂy when you turn the ignition key to RUN. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. Your brake system may not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to an accident. If the light is still on after you have pulled off the road and stopped carefully, have the vehicle towed for service. If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push or may go closer to the ﬂoor. It may take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 417. 250 If the regular brake system warning light is also on you do not have ABS and there is a problem with your regular brakes. In addition to both lights, you will also hear a chime sound on the ﬁrst occurrence of a problem and each time the vehicle is shut off and then restarted. See Brake System Warning Light on page 249. The ABS warning light should come on brieﬂy when you turn the ignition key to RUN. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. Anti-Lock Brake System Warning Light With the Anti-Lock Brake System (ABS), this light will come on when you start your engine and may stay on for several seconds. That is normal. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If the light stays on, or comes on when you are driving, your vehicle needs service. A chime will sound when the light stays on. If the regular brake system warning light is not on, you still have brakes, but you do not have ABS. 251 StabiliTrak® Indicator Light Engine Coolant Temperature Gage If equipped, this warning light should come on brieﬂy when the engine is started. If the warning light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If it stays on, or comes on when you are driving, there may be a problem with your StabiliTrak® system and your vehicle may need service. When this warning light is on, the system is off and will not limit wheel spin. Adjust your driving accordingly. This light will also ﬂash when the StabiliTrak® system is active. If the StabiliTrak® system warning light comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service. See StabiliTrak® System on page 363 for more information. 252 United States Canada This gage shows the engine coolant temperature. It also provides an indicator of how hard your vehicle is working. During a majority of the operation, the gage will read 210°F (100°C) or less. If you are pulling a load or going up hills, it is normal for the temperature to ﬂuctuate and approach the 250°F (122°C) mark. If the gage reaches the 260°F (125°C) mark, it indicates that the cooling system is working beyond its capacity. See Engine Overheating on page 473. Tire Pressure Light This light will come on brieﬂy when you turn the ignition to RUN. This light will also come on when one or more of your tires are signiﬁcantly underinﬂated. If your vehicle has a Driver Information Center (DIC), a CHECK TIRE PRESSURE DIC message will accompany the light. See DIC Warnings and Messages on page 270 for more information. Stop and check your tires as soon as it is safe to do so. If underinﬂated, inﬂate to the proper pressure. See Tires on page 507 for more information. This light will ﬂash for 60 seconds and then turn on solid if a problem is detected with the Tire Pressure Monitor system. See Tire Pressure Monitor System on page 516 for more information. Malfunction Indicator Lamp Check Engine Light Your vehicle has a computer which monitors operation of the fuel, ignition, and emission control systems. This system is called OBD II (On-Board Diagnostics-Second Generation) and is intended to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The check engine light comes on to indicate that there is a problem and service is required. Malfunctions often will be indicated by the system before any problem is apparent. This may prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction. 253 If you keep driving your vehicle with Notice: this light on, after awhile, the emission controls might not work as well, your vehicle’s fuel economy might not be as good, and the engine might not run as smoothly. This could lead to costly repairs that might not be covered by your warranty. Notice: Modiﬁcations made to the engine, transmission, exhaust, intake, or fuel system of your vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission controls and can cause this light to come on. Modiﬁcations to these systems could lead to costly repairs not covered by your warranty. This could also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modiﬁcations on page 444. This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If the light does not come on, have it repaired. This light will also come on during a malfunction in one of two ways: (cid:129) Light Flashing — A misﬁre condition has been detected. A misﬁre increases vehicle emissions and may damage the emission control system on your vehicle. Diagnosis and service may be required. (cid:129) Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service may be required. If the Light is Flashing The following may prevent more serious damage to your vehicle: (cid:129) Reducing vehicle speed (cid:129) Avoiding hard accelerations (cid:129) Avoiding steep uphill grades If you are towing a trailer, reduce the amount of cargo being hauled as soon as it is possible If the light stops ﬂashing and remains on steady, see “If the Light Is On Steady” following. 254 (cid:129) If the light continues to ﬂash, when it is safe to do so, stop the vehicle. Find a safe place to park your vehicle. Turn the key off, wait at least 10 seconds and restart the engine. If the light remains on steady, see “If the Light Is On Steady” following. If the light is still ﬂashing, follow the previous steps, and see your dealer for service as soon as possible. If the Light Is On Steady You may be able to correct the emission system malfunction by considering the following: Did you recently put fuel into your vehicle? If so, reinstall the fuel cap, making sure to fully install the cap. See Filling the Tank on page 451. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. Did you just drive through a deep puddle of water? If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off. Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See Gasoline Octane on page 447. Poor fuel quality will cause your engine not to run as efficiently as designed. You may notice this as stalling after start-up, stalling when you put the vehicle into gear, misﬁring, hesitation on acceleration, or stumbling on acceleration. (These conditions may go away once the engine is warmed up.) This will be detected by the system and cause the light to turn on. If you experience one or more of these conditions, change the fuel brand you use. It will require at least one full tank of the proper fuel to turn the light off. If none of the above steps have made the light turn off, your dealer can check the vehicle. Your dealer has the proper test equipment and diagnostic tools to ﬁx any mechanical or electrical problems that may have developed. 255 Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. Here are some things you need to know to help your vehicle pass an inspection: Your vehicle will not pass this inspection if the check engine light is on or not working properly. Your vehicle will not pass this inspection if the OBD (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if you have recently replaced your battery or if your battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This may take several days of routine driving. If you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, your dealer can prepare the vehicle for inspection. 256 Oil Pressure Gage United States Canada The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals). Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range. When the oil pressure reaches the low pressure zone, the OIL PRESSURE LOW STOP ENGINE message will appear in the Driver Information Center (DIC). See DIC Warnings and Messages on page 270 and Engine Oil on page 459 for more information. A reading in the low pressure zone may be caused by a dangerously low oil level or some other problem causing low oil pressure. Check your oil as soon as possible. {CAUTION: Do not keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches ﬁre. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. Notice: Lack of proper engine oil maintenance may damage the engine. The repairs would not be covered by your warranty. Always follow the maintenance schedule in this manual for changing engine oil. Oil Pressure Light This light will come on brieﬂy when you start your engine. {CAUTION: Do not keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches ﬁre. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. Notice: Lack of proper engine oil maintenance may damage the engine. The repairs would not be covered by your warranty. Always follow the maintenance schedule in this manual for changing engine oil. 257 That is a check to be sure the light works. If it does not come on, be sure to have it ﬁxed so it will be there to warn you if something goes wrong. When the light comes on and stays on, it means that oil is not ﬂowing through your engine properly. You could be low on oil and you might have some other system problem. Security Light Fog Lamp Light The fog lamp light will come on when the fog lamps are in use. This light ﬂashes when the vehicle security system is activated. The light will go out when the fog lamps are turned off. See Fog Lamps on page 218 for more information. Cruise Control Light This light comes on whenever you set the cruise control. The light goes out when the cruise control is turned off. See Cruise Control on page 211 for more information. 258 Highbeam On Light Fuel Gage This light comes on when the high-beam headlamps are in use. See Headlamp High/Low-Beam Changer on page 207 for more information. Tow/Haul Mode Light This light is displayed when the Tow/Haul mode has been activated. For more information, see Towing a Trailer on page 422 and Tow/Haul Mode on page 149. United States Canada The fuel gage, when the ignition is on, tells you about how much fuel you have left in your tank. The gage will ﬁrst indicate empty before you are out of fuel, and you should get more fuel as soon as possible. When the fuel tank is low, the FUEL LEVEL LOW message will appear in the Driver Information Center (DIC). See DIC Warnings and Messages on page 270 for more information. 259 Here are some situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage. (cid:129) At the gas station, the fuel pump shuts off before the gage reads full. It takes a little more or less fuel to ﬁll up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to ﬁll the tank. (cid:129) The gage goes back to empty when you turn off the ignition. Low Fuel Warning Light This light, under the fuel gage, will come on brieﬂy when you are starting the engine. 260 This light and a chime will come on when the fuel tank is low on fuel. There will also be a “FUEL LEVEL LOW” message on the Driver Information Center, see DIC Warnings and Messages on page 270 for more information. When you add fuel this light and message should go off. If it does not, have your vehicle serviced. Driver Information Center (DIC) Your vehicle has a Driver Information Center (DIC). The DIC displays information about your vehicle. It also displays warning messages if a system problem is detected. All messages will appear in the DIC display located below the tachometer in the instrument panel cluster. The DIC comes on when the ignition is on. After a short delay, the DIC will display the information that was last displayed before the engine was turned off. If your vehicle has DIC buttons, see “DIC Operation and Displays (With DIC Buttons)” later in this section and DIC Vehicle Customization (With DIC Buttons) on page 280 for the displays available. (cid:129) If your vehicle does not have DIC buttons, see “DIC Operation and Displays (Without DIC Buttons)” later in this section for the displays available. DIC Operation and Displays (With DIC Buttons) If your vehicle has DIC buttons, the information below explains the operation of this system. The DIC has different displays which can be accessed by pressing the DIC buttons located on the instrument panel, next to the steering wheel. The DIC displays trip, fuel, and vehicle system information, and warning messages if a system problem is detected. The DIC also allows some features to be customized. See DIC Vehicle Customization (With DIC Buttons) on page 280 for more information. If your vehicle has DIC buttons, you can also use the trip odometer reset stem to view some of the DIC displays. See “DIC Operation and Displays (Without DIC Buttons)” later in this section. DIC Buttons The buttons are the trip/fuel, vehicle information, customization, and set/reset buttons. The button functions are detailed in the following pages. 3 (Trip/Fuel): Press this button to display the odometer, trip odometer, fuel range, average economy, fuel used, timer, and transmission temperature. Some vehicles also display instantaneous economy and an Active Fuel Management™ indicator. 261 T (Vehicle Information): Press this button to display the oil life, units, tire pressure readings for vehicles with a Tire Pressure Monitor (TPM) system, engine hours, Tire Pressure Monitor (TPM) system programming for vehicles with a TPM system, and Remote Keyless Entry (RKE) transmitter programming. U (Customization): Press this button to customize the feature settings on your vehicle. See DIC Vehicle Customization (With DIC Buttons) on page 280 for more information. V (Set/Reset): Press this button to set or reset certain functions and to turn off or acknowledge messages on the DIC. Trip/Fuel Menu Items 3 (Trip/Fuel): Press this button to scroll through the following menu items: Odometer Press the trip/fuel button until ODOMETER displays. This display shows the distance the vehicle has been driven in either miles (mi) or kilometers (km). Pressing the trip odometer reset stem will also display the odometer. 262 To switch between English and metric measurements, see “Units” later in this section. Trip Odometer Press the trip/fuel button until TRIP displays. This display shows the current distance traveled in either miles (mi) or kilometers (km) since the last reset for the trip odometer. Pressing the trip odometer reset stem will also display the trip odometer. The trip odometer can be reset to zero by pressing the set/reset button while the trip odometer is displayed. You can also reset the trip odometer while it is displayed by pressing and holding the trip odometer reset stem. The trip odometer has a feature called the retro-active reset. This can be used to set the trip odometer to the number of miles (kilometers) driven since the ignition was last turned on. This can be used if the trip odometer is not reset at the beginning of the trip. To use the retro-active reset feature, press and hold the set/reset button for at least four seconds. The trip odometer will display the number of miles (mi) or kilometers (km) driven since the ignition was last turned on and the vehicle was moving. Once the vehicle begins moving, the trip odometer will accumulate mileage. For example, if the vehicle was driven 5 miles (8 km) before it is started again, and then the retro-active reset feature is activated, the display will show 5 miles (8 km). As the vehicle begins moving, the display will then increase to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc. If the retro-active reset feature is activated after the vehicle is started, but before it begins moving, the display will show the number of miles (mi) or kilometers (km) that were driven during the last ignition cycle. Fuel Range Press the trip/fuel button until FUEL RANGE displays. This display shows the approximate number of remaining miles (mi) or kilometers (km) the vehicle can be driven without refueling. The display will show LOW if the fuel level is low. The fuel range estimate is based on an average of the vehicle’s fuel economy over recent driving history and the amount of fuel remaining in the fuel tank. This estimate will change if driving conditions change. For example, if driving in traffic and making frequent stops, this display may read one number, but if the vehicle is driven on a freeway, the number may change even though the same amount of fuel is in the fuel tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving. Fuel range cannot be reset. Average Economy Press the trip/fuel button until AVG ECONOMY displays. This display shows the approximate average miles per gallon (mpg) or liters per 100 kilometers (L/100 km). This number is calculated based on the number of mpg (L/100 km) recorded since the last time this menu item was reset. To reset AVG ECONOMY, press and hold the set/reset button. 263 Fuel Used Press the trip/fuel button until FUEL USED displays. This display shows the number of gallons (gal) or liters (L) of fuel used since the last reset of this menu item. To reset the fuel used information, press and hold the set/reset button while FUEL USED is displayed. Timer Press the trip/fuel button until TIMER displays. This display can be used as a timer. To start the timer, press the set/reset button while TIMER is displayed. The display will show the amount of time that has passed since the timer was last reset, not including time the ignition is off. Time will continue to be counted as long as the ignition is on, even if another display is being shown on the DIC. The timer will record up to 99 hours, 59 minutes and 59 seconds (99:59:59) after which the display will return to zero. To stop the timer, press the set/reset button brieﬂy while TIMER is displayed. To reset the timer to zero, press and hold the set/reset button while TIMER is displayed. 264 Transmission Temperature Press the trip/fuel button until TRANS TEMP displays. This display shows the temperature of the automatic transmission ﬂuid in either degrees Fahrenheit (°F) or degrees Celsius (°C). Instantaneous Economy and Active Fuel Management™ Indicator If your vehicle has this display, press the trip/fuel button until INST ECONOMY V8 MODE displays. This display shows the current fuel economy at a particular moment and will change frequently as driving conditions change. This display shows the instantaneous fuel economy in miles per gallon (mpg) or liters per 100 kilometers (L/100 km). Unlike average economy, this screen cannot be reset. An Active Fuel Management™ indicator will display on the right side of the DIC, while INST ECONOMY displays on the left side. Active Fuel Management™ allows the engine to operate on either four or eight cylinders, depending on your driving demands. When Active Fuel Management™ is active, V4 MODE will display on the DIC. When Active Fuel Management™ is inactive, V8 MODE will display. See Active Fuel Management™ on page 145 for more information. Blank Display This display shows no information. Vehicle Information Menu Items T (Vehicle Information): Press this button to scroll through the following menu items: Oil Life Press the vehicle information button until OIL LIFE REMAINING displays. This display shows an estimate of the oil’s remaining useful life. If you see 99% OIL LIFE REMAINING on the display, that means 99% of the current oil life remains.

DIC Operation and Displays (Without DIC Buttons) If your vehicle does not have DIC buttons, the information below explains the operation of this system. The DIC has different displays which can be accessed by pressing the trip odometer reset stem located on the instrument panel cluster. Pressing the trip odometer reset stem will also turn off, or acknowledge, DIC messages. The DIC displays trip and vehicle system information, and warning messages if a system problem is detected. If your vehicle does not have DIC buttons, you can use the trip odometer reset stem to view the following displays: odometer, engine hours, trip odometer, oil life, Tire Pressure Monitor (TPM) system programming for vehicles with a TPM system, Remote Keyless Entry (RKE) transmitter programming, and display language. 267 Trip Odometer Press the trip odometer reset stem until TRIP displays. This display shows the current distance traveled in either miles (mi) or kilometers (km) since the last reset for the trip odometer. The trip odometer can be reset to zero by pressing and holding the trip odometer reset stem while the trip odometer is displayed. The trip odometer has a feature called the retro-active reset. This can be used to set the trip odometer to the number of miles (kilometers) driven since the ignition was last turned on. This can be used if the trip odometer is not reset at the beginning of the trip. To use the retro-active reset feature, press and hold the trip odometer reset stem for at least four seconds. The trip odometer will display the number of miles (mi) or kilometers (km) driven since the ignition was last turned on and the vehicle was moving. Once the vehicle begins moving, the trip odometer will accumulate mileage. For example, if the vehicle was driven 5 miles (8 km) before it is started again, and then the retro-active reset feature is activated, the display will show 5 miles (8 km). As the vehicle begins moving, the display will then increase to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc. If the retro-active reset feature is activated after the vehicle is started, but before it begins moving, the display will show the number of miles (mi) or kilometers (km) that were driven during the last ignition cycle. Oil Life To access this display, the vehicle must be in PARK (P). Press the trip odometer reset stem until OIL LIFE REMAINING displays. This display shows an estimate of the oil’s remaining useful life. If you see 99% OIL LIFE REMAINING on the display, that means 99% of the current oil life remains.

Some messages may not require immediate action, but you can press any of the DIC buttons on the instrument panel or the trip odometer reset stem on the instrument panel cluster to acknowledge that you received the messages and to clear them from the display. Some messages cannot be cleared from the DIC display because they are more urgent. These messages require action before they can be cleared. You should take any messages that appear on the display seriously and remember that clearing the messages will only make the messages disappear, not correct the problem. The following are the possible messages that can be displayed and some information about them. CHANGE ENGINE OIL SOON This message displays when the engine oil needs to be changed. When you change the engine oil, be sure to reset the CHANGE ENGINE OIL SOON message. See Engine Oil Life System on page 462 for information on how to reset the message. This message clears itself after 10 seconds until the next ignition cycle or until the message is reset. See Engine Oil on page 459 and Scheduled Maintenance on page 579 for more information. CHECK TIRE PRESSURE If your vehicle has a Tire Pressure Monitor (TPM) system, this message displays when the pressure in one or more of the vehicle’s tires need to be checked.
