2-65 3. Immediately return to your vehicle. Press and hold the Universal Home Remote button that you would like to use to control the garage door until the garage door moves. The indicator light, above the selected button, should slowly blink. You may need to hold the button from ﬁve to 20 seconds. 4. Immediately, within one second, release the button when the garage door moves. The indicator light will blink rapidly until programming is complete. 5. Press and release the same button again. The garage door should move, conﬁrming that programming is successful and complete. To program another Rolling Code device such as an additional garage door opener, a security device, or home automation device, repeat Steps 1 through 5, choosing a different function button in Step 3 than what you used for the garage door opener. If these instructions do not work, you probably have a Fixed Code garage door opener. Follow the Programming instructions that follow for a Fixed Code garage door opener. 2. Locate in the garage, the garage door opener receiver (motor-head unit). Locate the “Learn” or “Smart” button. It can usually be found where the hanging antenna wire is attached to the motor-head unit and may be a colored button. Press this button. After you press this button, you will have 30 seconds to complete the following steps. 2-66 To program up to three devices: Programming Universal Home Remote — Fixed Code If you have questions or need help programming the Universal Home Remote System, call 1-866-572-2728 or go to www.learcar2u.com. Most garage door openers sold before 1996 are Fixed Code units. Programming a garage door opener involves time-sensitive actions, so read the entire procedure before you begin. If you do not follow these actions, the device will time out and you will have to repeat the procedure. 1. To verify if you have a Fixed Code garage door opener, remove the battery cover on your hand held transmitter supplied by the manufacturer of your garage door opener motor. If you see a row of dip switches similar to the graphic above, you have a Fixed Code garage door opener. If you do not see a row of dip switches, return to the previous section for Programming Universal Home Remote – Rolling Code. Your hand held transmitter may have between eight to 12 dip switches depending on the brand of transmitter. 2-67 Your garage door opener receiver (motor head unit) may also have a row of dip switches that can be used when programming the Universal Home Remote. If the total number of switches on the motor head and hand held transmitter are different, or if the dip switch settings are different, use the dip switch settings on the motor head unit to program your Universal Home Remote. The motor head dip switch settings can also be used when you do not have the original hand held transmitter. Example of Eight Dip Switches with Three Positions Your panel of switches may not appear exactly as they do in the examples, but they should be similar. The switch positions on your hand-held transmitter may be labeled as follows: (cid:129) A switch in the up position may be labeled as “Up,” “+,” or “On.” (cid:129) A switch in the down position may be labeled as “Down,” “−,” or “Off.” (cid:129) A switch in the middle position may be labeled as “Middle,” “0,” or “Neutral.” Example of Eight Dip Switches with Two Positions 2-68 2. Write down the eight to 12 switch settings from left to right as follows: (cid:129) When a switch is in the up position, write “Left.” (cid:129) When a switch is in the down position, write “Right.” If a switch is set between the up and down position, write “Middle.” The switch settings that you wrote down in Step 2 will now become the button strokes you enter into the Universal Home Remote in Step 4. Be sure to enter the switch settings that you wrote down in Step 2, in order from left to right, into the Universal Home Remote, when completing Step 4. 3. From inside your vehicle, ﬁrst ﬁrmly press all three buttons at the same time for about three seconds. Release the buttons to put the Universal Home Remote into programming mode. 4. The indicator lights will blink slowly. Enter each switch setting from Step 2 into your vehicle’s Universal Home Remote. You will have two and one-half minutes to complete Step 4. Now press one button on the Universal Home Remote for each switch setting as follows: If you wrote “Left,” press the left button in the vehicle. If you wrote “Right,” press the right button in the vehicle. If you wrote “Middle,” press the middle button in the vehicle. 2-69 (cid:129) (cid:129) (cid:129) (cid:129) 5. After entering all of the switch positions, again, ﬁrmly press and release all three buttons at the same time. The indicator lights will turn on. 6. Press and hold the button you would like to use to control the garage door until the garage door moves. The indicator light above the selected button should slowly blink. You may need to hold the button from ﬁve to 55 seconds. 7. Immediately release the button when the garage door moves. The indicator light will blink rapidly until programming is complete. 8. Press and release the same button again. The garage door should move, conﬁrming that programming is successful and complete. To program another Fixed Code device such as an additional garage door opener, a security device, or home automation device, repeat Steps 1-8, choosing a different button in Step 6 than what you used for the garage door opener. Using Universal Home Remote Press and hold the appropriate button for at least half of a second. The indicator light will come on while the signal is being transmitted. Reprogramming Universal Home Remote Buttons You can reprogram any of the three buttons by repeating the instructions. Erasing Universal Home Remote Buttons You should erase the programmed buttons when you sell or terminate your lease. To erase either Rolling Code or Fixed Code on the Universal Home Remote device: 1. Press and hold the two outside buttons at the same time for approximately 20 seconds, until the indicator lights, located directly above the buttons, begin to blink rapidly. 2. Once the indicator lights begin to blink, release both buttons. The codes from all buttons will be erased.

Flash-to-Pass. See Flash-to-Pass on page 3-9. N(Windshield Wipers): See Windshield Wipers on page 3-9. 3-7 L(Windshield Washer): See Windshield Washer on page 3-11. 5 (Rear Wiper Delay): See Rear Window Wiper/Washer on page 3-12. Z (Rear Wiper): See Rear Window Wiper/Washer on page 3-12. =(Rear Wiper Wash): See Rear Window Wiper/Washer on page 3-12. Turn and Lane-Change Signals The turn signal has two upward (for right) and two downward (for left) positions. These positions allow you to signal a turn or a lane change. To signal a turn, move the lever all the way up or down. When the turn is ﬁnished, the lever will return automatically. To signal a lane change, raise or lower the lever for less than one second until the arrow starts to ﬂash. This will cause the turn signals to automatically ﬂash three times. It will ﬂash six times if tow-haul mode is active. Holding the turn signal lever for more than one second will cause the turn signals to ﬂash until you release the lever. The lever will return by itself when it is released. 3-8 An arrow on the instrument panel cluster will ﬂash in the direction of the turn or lane change. As you signal a turn or a lane change, if the arrows ﬂash more quickly than normal, a signal bulb may be burned out and other drivers will not see your turn signal. If a bulb is burned out, replace it to help avoid an accident. If the arrows do not go on at all when you signal a turn, check for burned-out bulbs and a blown fuse. See Fuses and Circuit Breakers on page 5-117. Turn Signal On Chime If your turn signal is left on for more than 3/4 of a mile (1.2 km), a chime will sound at each ﬂash of the turn signal and the message TURN SIGNAL ON will also appear in the Driver Information Control (DIC). To turn the chime and message off, move the turn signal lever to the off position. Headlamp High/Low-Beam Changer 53(Headlamp High/Low Beam Changer): To change the headlamps from low to high beam, push the lever toward the instrument panel. To return to low-beam headlamps, pull the multifunction lever toward you. Then release it. When the high beams are on, this indicator light on the instrument panel cluster will also be on. Flash-to-Pass This feature lets you use your high-beam headlamps to signal a driver in front of you that you want to pass. It works even if your headlamps are in the automatic position. To use it, pull the turn signal lever toward you, then release it. If your headlamps are in the automatic position or on low beam, your high-beam headlamps will turn on. They will stay on as long as you hold the lever toward you. The high-beam indicator on the instrument panel cluster will come on. Release the lever to return to normal operation. Windshield Wipers Clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, gently loosen or thaw them. Damaged wiper blades may not clear the windshield well, making it harder to see and drive safely. If the blades do become damaged, install new blades or blade inserts. For more information, see Windshield Wiper Blade Replacement on page 5-61. Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools down. Clear away snow or ice to prevent an overload. 3-9 Turn the band with the wiper symbol to control the windshield wipers. 8(Mist): Turn the band to mist for a single wiping cycle. Hold it there until the wipers start. Then let go. The wipers stop after one wipe. Hold the band on mist longer, for more wipe cycles. 9(Off): To stop the wipers, move the band to off. 6 (Delay): Turn the band to adjust the delay time. The delay between wiping cycles becomes shorter as the band is moved to the top of the lever. This can be very useful in light rain or snow. 6 (Low Speed): Turn the band away from you to the ﬁrst solid band past the delay settings, for steady wiping at low speed. ? (High Speed): Turn the band further, to the second solid band past the delay settings, for high-speed wiping. Rainsense™ II Wipers If your vehicle has Rainsense™ II windshield wipers, the moisture sensor is located next to the inside rearview mirror and is mounted on the windshield. When active, these sensors are able to detect moisture on the windshield and automatically turn on the wipers. To turn on the Rainsense™ feature, the wipers must be set to one of the ﬁve delay settings on the multifunction lever. Each of the ﬁve settings adjusts the sensitivity of the rainsensor. Since different drivers have different setting preferences, it is recommended that the mid-range setting (position 3) be used initially. For more wipes, select the higher settings; for fewer wipes, select the lower settings located closer to the off position on the multifunction lever. The rainsensor will automatically control the frequency of the wipes from the off setting to the high speed setting according to the weather conditions. The wipers can be left in a rainsense mode even when it is not raining. When Rainsense™ is active, the headlamps will turn on automatically if the exterior lamp control is in the AUTO position and the wipers are active. Notice: Going through an automatic car wash with the wipers on can damage them. Turn the wipers off when going through an automatic car wash. 3-10 Windshield Washer {CAUTION: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer ﬂuid can form ice on the windshield, blocking your vision. L (Washer Fluid): Push the paddle marked with the windshield washer symbol at the top of the multifunction lever, to spray washer ﬂuid on the windshield. The wipers clear the window and then either stop or return to the preset speed. Heated Windshield Washer For vehicles with the heated windshield washer ﬂuid system it can be used to help clear ice, snow, tree sap, or bugs from your windshield. The button is located in the switchbank under the climate controls. Push the heated washer ﬂuid button to activate the heated windshield washer ﬂuid system. The indicator light will ﬂash. This activation initiates four heated wash/wipe cycles. The ﬁrst heated wash/wipe cycle may take up to 40 seconds to occur, depending on outside temperature. After the ﬁrst wash/wipe cycle, it may take up to 20 seconds for each of the remaining cycles to begin. Press the button again to turn off the heated windshield washer ﬂuid system or it will automatically turn off after four wipe cycles have been completed. When the heated windshield washer ﬂuid system is activated under certain outside temperature conditions, steam may ﬂow out of the washer nozzles for a short period of time before washer ﬂuid is sprayed. This is a normal condition. 3-11 Rear Window Wiper/Washer {CAUTION: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer ﬂuid can form ice on the windshield, blocking your vision. The rear wiper control is located on the turn signal/multifunction lever.

If the liftgate or liftglass is opened while the rear wiper is on, the wiper will return to the parked position and stop. Cruise Control {CAUTION: Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use your cruise control on winding roads or in heavy traffic. CAUTION: (Continued) 3-12 CAUTION: (Continued) Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). When you apply your brakes, cruise control is turned off. If your vehicle has the StabiliTrak® system and begins to limit wheel spin while you are using cruise control, the cruise control will automatically disengage. See StabiliTrak® System on page 4-6. When road conditions allow you to safely use it again, you may turn the cruise control back on. The cruise control buttons are located on left side of the steering wheel. T(On/Off): This button can both activate and turn off the system. The indicator light on the button turns on when cruise control is on and turns off when cruise control is off. + RES (Resume/Accelerate): Press this button to make the vehicle accelerate or resume to a previously set speed. SET − (Set/Coast): Press this button to set the speed or make the vehicle decelerate. [ (Cancel): Press this button to cancel cruise control without erasing the set speed from memory. 3-13 Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake. This shuts off the cruise control. But you do not need to reset it. Once you are driving about 25 mph (40 km/h) or more, press the +RES button on your steering wheel. The vehicle will go back to the previous set speed and stay there. Increasing Speed While Using Cruise Control To increase the cruise speed while using cruise control: (cid:129) Press and hold the +RES button on the steering wheel until you reach your new desired speed, then release it.

Setting Cruise Control Cruise control will not work if your parking brake is set, or if the master cylinder brake ﬂuid level is low. The cruise control light on the instrument panel cluster will come on after the cruise control has been set to the desired speed. {CAUTION: If you leave your cruise control on when you are not using cruise, you might hit a button and go into cruise when you do not want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control. 1. Press the cruise control On/Off button. 2. Get up to the desired speed. 3. Press the SET− button located on the steering wheel and release it. 4. Take your foot off the accelerator. 3-14 (cid:129) Reducing Speed While Using Cruise Control To reduce your speed while using cruise control: (cid:129) Press and hold the SET– button on the steering wheel until the desired lower speed is reached, then release it. To slow down in very small amounts, press the SET– button on the steering wheel brieﬂy. Each time you do this, the vehicle will go about 1 mph (1.6 km/h) slower. Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase your speed. When you take your foot off the pedal, your vehicle will slow down to the previous set cruise speed. Using Cruise Control on Hills How well your cruise control will work on hills depends upon your speed, load, and the steepness of the hills. When going up steep hills, you may have to step on the accelerator pedal to maintain the vehicle’s speed. When going downhill, you may have to brake or shift to a lower gear to keep the vehicle’s speed down. Of course, applying the brake takes you out of cruise control. Many drivers ﬁnd this to be too much trouble and do not use cruise control on steep hills. Ending Cruise Control There are three ways to end cruise control: (cid:129) Step lightly on the brake pedal. (cid:129) Press the cancel button on the steering wheel. (cid:129) Press the On/Off button on the steering wheel. Erasing Speed Memory When you turn off the cruise control or the ignition, the cruise control set speed memory is erased. 3-15 (cid:129) Exterior Lamps The exterior lamps control is located on the instrument panel to the left of the steering wheel. It controls the following systems: (cid:129) Headlamps Taillamps (cid:129) Parking Lamps License Plate Lamps Instrument Panel Lights The exterior lamps control has four positions: O(Off): Turn the control to this position to turn off the automatic headlamps and daytime running lamps (DRL). Turning the headlamp control to the off position again will turn the automatic headlamps or DRL back on. For vehicles ﬁrst sold in Canada, the off position will only work for vehicles that are shifted into the PARK (P) position. 3-16 AUTO (Automatic): Turn the control to this position to automatically turn on the headlamps at normal brightness, together with the following: (cid:129) Parking Lamps Instrument Panel Lights Taillamps License Plate Lamps ;(Parking Lamps): Turn the control to this position to turn on the parking lamps together with the following: Instrument Panel Lights Taillamps License Plate Lamps 2(Headlamps): Turn the control to this position to turn on the headlamps together with the following lamps listed below. (cid:129) Parking Lamps Instrument Panel Lights Taillamps License Plate Lamps (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) When the headlamps are turned on while the vehicle is on, the headlamps turn off automatically 10 minutes after the ignition is turned off. When the headlamps are turned on while the vehicle is off, the headlamps will stay on for 10 minutes before automatically turning off to prevent the battery from being drained. Headlamps on Reminder A reminder chime will sound when the headlamps or parking lamps are manually turned on and your ignition is off and a door is open. To disable the chime, turn the light off. Daytime Running Lamps (DRL) Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. DRL can be helpful in many different 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. The DRL system will come on when the following conditions are met: The ignition is on. The exterior lamps control is in AUTO. The transmission is not in PARK (P). The light sensor determines it is daytime. When the DRL are on, only the 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 transmission must be in the PARK (P) position, before the DRL lamps can be turned off. 3-17 (cid:129) (cid:129) (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 it. For vehicles ﬁrst sold in Canada, the transmission 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. 3-18 If the vehicle is started in a dark garage, the automatic headlamp system will come on immediately. Once the vehicle leaves the garage, it takes approximately one minute for the automatic headlamp system to change to DRL if it is bright enough outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position. See Instrument Panel Brightness on page 3-19. To idle the vehicle with the automatic headlamp system off, turn the control to the off position. The headlamps will also stay on after you exit the vehicle. This feature can be programmed using the Driver Information Center (DIC). See DIC Vehicle Customization (With DIC Buttons) on page 3-73. The regular headlamp system can be turned on when needed. Fog Lamps -(Fog Lamps): If your vehicle has fog lamps, the control is located next to the exterior lamps control on the instrument panel to the left of the steering column. The ignition must be in the ON/RUN position for the fog lamps to come on. Press the button to turn the fog lamps on or off. A light will come on in the instrument panel cluster. When the fog lamps are turned on, the parking lamps automatically turn on. When the headlamps are changed to high-beam, the fog lamps also go off. When the high-beam headlamps go off, the fog lamps will come on again. Some localities have laws that require the headlamps to be on along with the fog lamps. 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 4-41. Instrument Panel Brightness D(Instrument Panel Brightness): This feature controls the brightness of the instrument panel lights and is located next to the exterior lamp control. Push the knob to extend out and then it can be turned. Turn the knob clockwise or counterclockwise to brighten or dim the instrument panel lights. Turning the knob to the farthest clockwise position turns on the dome lamps. 3-19 Exit Lighting The interior lamps come on when the key is removed from the ignition. They turn off automatically in 20 seconds. The lights do 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. Dome Lamps The dome lamps come on when any door is opened. They turn off after all the doors are closed. The dome lamps can also be turned on by turning the instrument panel brightness knob, located next to the exterior lamps control, clockwise to the farthest position. In this position, the dome lamps remain on whether a door is opened or closed. Dome Lamp Override The dome lamp override button is located next to the exterior lamps control. k (Dome Off): Press the button in and the dome lamps remain off when a door is opened. Press the button again to return it to the extended position so that the dome lamps come on when a door is opened. 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. 3-20 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 a 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. 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 3-65. 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. 3-21 Accessory Power Outlet(s) Accessory power outlets can be used to connect auxiliary electrical equipment, such as a cellular telephone or CB radio. There are two under the climate controls, one inside the center ﬂoor console, one on the rear of the center ﬂoor console and one accessory power outlet in the rear cargo area on the passenger side. To use an accessory power outlet, remove the protective cap. When not in use, always cover the accessory power outlet with the protective cap. The accessory power outlets are powered, even with the ignition off. Continuing to use accessory power outlets while the ignition is in LOCK/OFF may cause the vehicle’s battery to run down. Notice: 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. If electrical devices are left plugged into a Certain 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/retailer 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: 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. Improper use of the power outlet can cause 3-22 If you put papers, pins, or other ﬂammable 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: 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 The heating, cooling, defrost, defog and ventilation of your vehicle can be controlled with this system. Manual Operation Turn the right knob clockwise or counterclockwise to direct the airﬂow inside of the vehicle. 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. 3-23 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 the vehicle. Recirculation may also help cool the air inside the 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. AUX (Auxiliary): Pressing this button will turn the rear heating and air conditioning on. See Rear Air Conditioning and Heating System on page 3-33 or Rear Air Conditioning and Heating System and Electronic Climate Controls on page 3-35 for more information. 3-24 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, if equipped. Otherwise, turn the center knob clockwise or counterclockwise to increase or decrease the temperature inside the vehicle. #(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 comes on to show 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 a small amount of water might drip underneath the 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. - (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 this mode is selected, 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 the 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. 3-25 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. 3-26 Dual Automatic Climate Control System The heating, cooling, and ventilation in your vehicle can be controlled with this system. Your vehicle also has a ﬂow-through ventilation system described later in this section. If your vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information. Different climate control settings can be selected for the driver and passengers. 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. 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. 3-27 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 the vehicle. The light on the button will illuminate in recirculation. 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 the 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. 3-28 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 vent or bi-level mode has been selected. The temperature can also be adjusted using either temperature button. If the air delivery mode or temperature settings are adjusted 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. Manual Operation You may manually adjust the air delivery mode or fan speed. y9z(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 the 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. 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. 3-29 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 automatically selects 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 comes on. This mode keeps outside air from entering the vehicle. It can be used to reduce outside air and prevent odors from entering the vehicle. Recirculation may also help cool the air inside the 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. 3-30 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 comes on to show 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 show that 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 a small amount of water might drip underneath the vehicle while idling or after turning off the engine. This is normal. 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 if equipped, in the headliner above the second row seats measure the temperature of the air inside the 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. 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. 3-31 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. 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. 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 this mode is selected, 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 the 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. 3-32 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. 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. If the rear controls are adjusted, the system will enter a rear independent mode. Airﬂow in the rear will then be directed according to the settings of rear controls. The rear system can be turned off by pressing the AUX button on the front climate control system and the indicator will turn off. 3-33 Mode Knob The right knob on the control panel allows you to choose the direction of air delivery. H(Vent): This setting directs the air through the headliner outlets. )(Bi-Level): Air is delivered through the ﬂoor outlets as well as the headliner outlets.

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 3-65 for more information. 3-37 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. If your vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information. 3-38 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 Reminders Safety Belt Reminder Light When the engine is started, a chime will come on for several seconds to remind people to fasten their safety belts, unless the driver’s safety belt is already buckled. The safety belt light will also come on and stay on for several seconds, then it will ﬂash for several more. This chime and light is repeated if the driver remains unbuckled and the vehicle is in motion. If the driver’s belt is already buckled, neither the chime nor the light will come on. 3-39 Passenger Safety Belt Reminder Light Several seconds after the engine is started, a chime will sound for several seconds to remind the front passenger to buckle their safety belt. This would only occur if the passenger airbag is enabled. See Passenger Sensing System on page 1-86 for more information. The passenger safety belt light, located on the instrument panel, will come on and stay on for several seconds and then ﬂash for several more. This chime and light are repeated if the passenger remains unbuckled and the vehicle is in motion. If the passenger’s safety belt is buckled, neither the chime nor the light will come on. Airbag Readiness Light There is an airbag readiness light on the instrument panel cluster, 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 sensor, the pretensioners, the airbag modules, the wiring and the crash sensing and diagnostic module. For more information on the airbag system, see Airbag System on page 1-76. This light will come on when you start your vehicle, and it will ﬂash for a few seconds. The light should go out and the system is ready. 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. 3-40 {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. Passenger Airbag Status Indicator Your vehicle has the passenger sensing system. Your overhead console has a passenger airbag status indicator. United States Canada The airbag readiness light should ﬂash for a few seconds when you start the engine. If the light does not come on then, have it ﬁxed immediately. If there is a problem with the airbag system, an airbag Driver Information Center (DIC) message may also come on. See DIC Warnings and Messages on page 3-65 for more information. When you start the vehicle, 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. 3-41 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. 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 1-86 for more on this, including important safety information. 3-42 If, after several seconds, both 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/retailer for service. {CAUTION: If the airbag readiness light in the instrument panel cluster ever comes on and stays on, 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’s seat may not have the protection of the airbag(s). See Airbag Readiness Light on page 3-40 for more on this, including important safety information. Charging System Light This 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. A charging system Driver Information Center (DIC) message may also appear. See DIC Warnings and Messages on page 3-65 for more information. This light could indicate that you have problems with a generator drive belt, or another electrical problem. Have it checked right away. 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. 3-43 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 3-65 and Charging System Light on page 3-43 for more information. Voltmeter Gage When your engine is not running, but the ignition is on, this gage shows the 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. The gage may also read low during the fuel economy mode, this is normal. 3-44 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. This light may also come on due to low brake ﬂuid. See Brakes on page 5-42 for more information. 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. {CAUTION: 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 4-45. United States Canada 3-45 Antilock Brake System Warning Light For vehicles with the Antilock Brake System (ABS), this light will come on brieﬂy when you start the engine. StabiliTrak® Indicator Light 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 4-6 for more information. 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 ABS light stays on, turn the ignition off, if the light comes on when you are driving, stop as soon as it is safely possible and turn the ignition off. Then start the engine again to reset the system. If the ABS light still stays on, or comes on again while you are driving, your vehicle needs service. If the regular brake system warning light is not on, you still have brakes, but you do not have antilock brakes. If the regular brake system warning light is also on, you do not have antilock brakes and there is a problem with your regular brakes. See Brake System Warning Light on page 3-45 For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-65 for all brake related DIC messages. 3-46 Engine Coolant Temperature Gage Tire Pressure Light This light comes on brieﬂy when the engine is started. 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 5-31. If your vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information. This light will also come on when one or more of your tires are signiﬁcantly underinﬂated. A tire pressure message in the Driver Information Center (DIC), may accompany the light. See DIC Warnings and Messages on page 3-65 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 5-63 for more information. If a problem is detected with the Tire Pressure Monitor System, this light will ﬂash for approximately 60 seconds and then stay on solid for the remainder of the ignition cycle. See Tire Pressure Monitor System on page 5-71 for more information. 3-47 Malfunction Indicator Lamp Check Engine Light A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors operation of the fuel, ignition, and emission control systems. It makes sure 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 an OBD II problem and service is required. If you keep driving your vehicle with this Notice: light on, after a while, 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 5-3. Malfunctions often are indicated by the system before any problem is apparent. This can prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction. 3-48 This light comes on, as a check to show it is working, when the ignition is turned ON/RUN but the engine is not running. If the light does not come on, have it repaired. This light also comes on during a malfunction in one of two ways: Light Flashing — A misﬁre condition has been detected. A misﬁre increases vehicle emissions and could damage the emission control system on your vehicle. Diagnosis and service might be required. Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service might be required. If the Light is Flashing The following can prevent more serious damage to your vehicle: (cid:129) Reduce vehicle speed. (cid:129) Avoid hard accelerations. (cid:129) Avoid 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. If the light continues to ﬂash, when it is safe to do so, stop the vehicle. Find a safe place to park the vehicle. Turn the ignition 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/retailer for service as soon as possible.
