Your front and rear turn signal lamps will ﬂash on and off. The hazard warning ﬂasher button is located near the center of the instrument panel. Your hazard warning ﬂashers work no matter what mode the ignition is in, even if the ignition is turned off. Press the button to make the front and rear turn signal lamps ﬂash on and off. Press the button again to turn the ﬂashers off. When the hazard warning ﬂashers are on, your turn signals will not work. Other Warning Devices If you carry reﬂective triangles, you can set them up at the side of the road about 300 feet (100 m) behind your vehicle. Horn Press near or on the horn symbols on the steering wheel pad to sound the horn. 3-6 Tilt Wheel A tilt wheel allows you to adjust the steering wheel before you drive. You can raise it to the highest level to give your legs more room when you exit and enter the vehicle. The lever that allows you to tilt the steering wheel is located on the left side of the steering column. Telescopic Steering Column If your vehicle has this feature, the telescopic steering column will allow you to adjust the distance the steering wheel is from the instrument panel. The telescopic steering column switch is located on the right side of the steering column. To tilt the wheel, hold the steering wheel and pull the lever toward you. Then move the wheel to a comfortable position and release the lever to lock the wheel in place. To operate the telescopic steering column, push the switch forward and the wheel will move away from you. Pull the switch rearward and the wheel will move toward you The telescopic steering column position can be stored with your memory settings. See Memory Seat, Mirrors and Steering Wheel on page 1-4 for more information. 3-7 Turn Signal/Multifunction Lever The lever on the left side of the steering column includes the following: (cid:129) G Turn and Lane-Change Signals. See Turn and Lane-Change Signals (Auto Signal) on page 3-8. (cid:129) 3 Headlamp High/Low-Beam Changer. See Headlamp High/Low-Beam Changer on page 3-9. (cid:129) - Fog Lamps. See Fog Lamps on page 3-17. Flash-to-Pass Feature. See Flash-to-Pass on page 3-9. (cid:129) I Cruise Control. See Cruise Control on (cid:129) P Exterior Lamps Control. See Exterior Lamps on page 3-11. page 3-15. 3-8 Turn and Lane-Change Signals (Auto Signal) 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 multifunction lever all the way up or down. When the turn is ﬁnished, the lever will return automatically. An arrow on the instrument panel cluster will ﬂash in the direction of the turn or lane change. To signal a lane change, just raise or lower the lever until the arrow starts to ﬂash. Release the lever and the turn signal will automatically ﬂash three times. If more ﬂashes are desired, continue to hold the lever. If you signal a turn or a lane change and the arrows ﬂash faster than normal, a signal bulb may be burned out. 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 the fuses and check for burned-out bulbs. See Fuses and Circuit Breakers on page 5-96. (cid:129) Turn Signal on Chime A chime will remind you if you leave the turn signal on for more than three-quarters of a mile (1.2 km) of driving. If you need to leave the turn signal on for more than three-quarters of a mile (1.2 km), turn off the signal and then turn it back on. Headlamp High/Low-Beam Changer To change the headlamps from low beam to high, push the turn signal lever all the way forward. To change from high to low beam, pull the lever rearward. While the high beams are on, this light on the instrument panel cluster will also be lit. Flash-to-Pass To use the ﬂash-to-pass feature, brieﬂy pull the turn signal lever toward you. The high-beam indicator ﬂashes to indicate to the other driver that you intend to pass. If the low-beam headlamps are off and the fog lamps are on, the fog lamps ﬂash. Windshield Wipers Use the lever located on the right side of the steering column to operate the windshield wipers. 1 (High Speed): Move the lever to this position for steady wiping at high speed. 6 (Low Speed): Move the lever to this position for steady wiping at low speed. & (Delay): Move the lever to this position to set a delay between wipes. x (Delay Adjustment): Move the lever to this position to choose a delayed wiping cycle. Turn the intermittent adjust band down for a longer delay or up for a shorter delay. The wiper speed can only be manually adjusted when the lever is in this position. 3-9 {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. If the ﬂuid in the windshield washer ﬂuid reservoir is low, the message CHECK WASHER FLUID will appear on the Driver Information Center (DIC) display. It will take 15 seconds after the bottle is reﬁlled for this message to turn off. For information on the correct washer ﬂuid to use, see Windshield Washer Fluid on page 5-41 and Recommended Fluids and Lubricants on page 6-11. 9(Off): Move the lever to this position to turn off the windshield wipers. 8(Mist): Move the lever all the way down to mist and release for a single wiping cycle. The windshield wipers will stop after one wipe. If you want more wipes, hold the band on mist longer. Heavy snow or ice can overload the wipers. If this occurs, a circuit breaker will stop the wipers until the motor cools. So, be sure to clear any ice and snow from the windshield wiper blades before using them. If the wiper blades are frozen to the windshield, carefully loosen them or warm the windshield before turning the wipers on. If your blades do become worn or damaged, get new blades or blade inserts. Windshield Washer The lever on the right side of the steering column also controls the windshield washer. There is a button at the end of the lever. To spray washer ﬂuid on the windshield, press the button and hold it. The washer will spray until you release the button. The wipers will continue to clear the window for about six seconds after the button is released and then stop or return to your preset speed. 3-10 Cruise Control Your vehicle has cruise control. 9 (Off): Slide the switch to this position to turn the system off. R (On): Slide the switch to this position to turn the system on. + (Resume/Accelerate): Slide the switch to this position to make the vehicle accelerate or resume a previously set speed. T (Set): Press this button at the end of the lever to set the speed. 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). Cruise control will not work if your parking brake is set, or if the master cylinder brake ﬂuid level is low. {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. 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. If your vehicle is in cruise control, and has the Traction Control System (TCS), and it begins to limit wheel spin, the cruise control automatically disengages. See Traction Control System (TCS) on page 4-6. When road conditions allow you to safely use it again, you can turn cruise control back on. 3-11 Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake. This, of course, disengages the cruise control. But you do not need to reset it. Once you are going about 25 mph (40 km/h) or more, you can move the cruise control switch brieﬂy from on to resume/accelerate. You will go right back up to your chosen speed and stay there. If you hold the switch at resume/accelerate the vehicle keeps going faster until you release the switch or apply the brake. Do not hold the switch at resume/accelerate, unless you want the vehicle to go faster. Setting Cruise Control {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. Move the cruise control switch to on. 2. Get up to the speed desired. 3. Press in the set button at the end of the lever and release it. 4. Take your foot off the accelerator pedal. When the cruise control is engaged, the CRUISE SET TO XX MPH message displays on the Driver Information Center (DIC). See Other Messages on page 3-71. 3-12 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 slows down to the cruise control speed you set earlier. 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 might want to step on the accelerator pedal to maintain the vehicle’s speed. When going downhill, you might have to brake or shift to a lower gear to keep the vehicle’s speed down. Of course, applying the brake turns off the cruise control. Many drivers ﬁnd this to be too much trouble and do not use cruise control on steep hills. Increasing Speed While Using Cruise Control There are two ways to go to a higher speed: (cid:129) Use the accelerator pedal to get to the higher speed. Press the set button at the end of the lever, then release the button and the accelerator pedal. You will now cruise at the higher speed. If the accelerator pedal is held longer than 60 seconds, cruise control will turn off. (cid:129) Move the cruise switch from on to resume/accelerate. Hold it there until you get up to the speed desired, and then release the switch. To increase your speed in very small amounts, move the switch brieﬂy to resume/accelerate. Each time you do this, your vehicle will go about 1 mph (1.6 km/h) faster. Reducing Speed While Using Cruise Control (cid:129) Press and hold the set button until you reach the lower speed you want, then release it. To slow down in very small amounts, brieﬂy press the set button. Each time you do this, you will go about 1 mph (1.6 km/h) slower. 3-13 (cid:129) Ending Cruise Control To end a cruise control session, step lightly on the brake pedal. If your vehicle has a manual transmission, lightly tapping the clutch will also end a cruise control session. Move the cruise control switch to off to turn the system completely off. When cruise control is disengaged, the CRUISE DISENGAGED message displays on the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-55. Erasing Speed Memory When you turn off the cruise control or the ignition, the cruise control set speed memory is erased. Cruise Control in Sport (S) and Manual Paddle Shift Gear Selection When your vehicle is in Sport (S) and the manual paddle shift controls are not being used, cruise control operates in the same manner as Drive (D). When your vehicle is in Sport (S) and the manual paddle shift controls are being used, cruise control operates as follows: If cruise control is active and a gear is selected with the manual paddle shift controls, the vehicle maintains vehicle speed in the driver selected gear and will not automatically up-shift or down-shift the transmission while the driver’s gear selection is active. If driving in hilly terrain, cruise control may not be able to maintain vehicle speed if an up-shift or down-shift is not selected by the driver. While driving on hilly terrain and cruise control is active with a manual paddle shift gear selection, the driver must select the proper gear for the terrain or select Drive (D) on the gear range selector for full automatic transmission operation. 3-14 (cid:129) (cid:129) Exterior Lamps The exterior lamp control is located to the left of the steering wheel on the multifunction lever. O(Exterior Lamp Control): Turn the band with this symbol on it to operate the exterior lamps. The exterior lamp band has four positions: O(Off): Turn the band to this position to turn off all lamps. AUTO (Automatic): Turn the band to this position to set the exterior lamps in automatic mode. AUTO mode turns the exterior lamps on and off depending on how much light is available outside the vehicle. To override AUTO mode, turn the control to off. To reset to AUTO mode turn the control to exterior lamps and then back to AUTO. Automatic mode also resets when your vehicle is turned off and then back on again if the control is left in the AUTO position. ;(Parking Lamp): Turning the band to this position turns on the parking lamps together with the following: (cid:129) Sidemarker Lamps Taillamps License Plate Lamps Instrument Panel Lights The parking brake indicator light comes on and stays on when the parking lamps are on with the engine off and the ignition to Acc. 5(Headlamps): Turning the control to this position turns on the headlamps, together with the previously listed lamps and lights. 3-15 (cid:129) (cid:129) (cid:129) Wiper Activated Headlamps This feature activates the headlamps and parking lamps after the windshield wipers have been in use for approximately 15 seconds and deactivates and returns to ambient lighting conditions 15 seconds after the wipers are turned off. If the exterior lamp control has been turned off or is in the parking lamp position while the wiper control is active in any position, the HEADLAMPS SUGGESTED message appears on the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-55. When the ignition is turned off, the wiper-activated headlamps will immediately turn off. Headlamps on Reminder A warning chime will sound if the exterior lamp control is left on in either the headlamp or parking lamp position and the driver’s door is opened with the ignition 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 make the front turn signal lamps come on when the following conditions are met: It is still daylight and the ignition is on. The exterior lamp control is in the AUTO position. The transmission is not in PARK (P) or the parking brake is off. The parking brake is off or the vehicle speed is greater than 8 mph (13 km/h). When DRL are on, only the front turn signal lamps will be on. No other exterior lamps such as the parking lamps, taillamps, etc. will be on when the DRL are being used. The instrument panel will not be lit up either. When it is dark enough outside, the front turn signal lamps turn off and the normal low-beam headlamps turn on. 3-16 (cid:129) (cid:129) (cid:129) (cid:129) When it is bright enough outside, the regular lamps go off, and the front turn signal lamps will take over. 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 light outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness knob is in the full bright position. See Instrument Panel Brightness on page 3-19 for more information. If it is dark enough outside and the exterior lamp control is off, a HEADLAMPS SUGGESTED message will display on the Driver’s Information Center (DIC). See DIC Warnings and Messages on page 3-55. Turning the exterior lamp control to off a second time, or turning on the headlamps will remove the HEADLAMPS SUGGESTED message in the DIC. If the parking lamps or the fog lamps were turned on instead, the HEADLAMPS SUGGESTED message will continue to be displayed. The regular headlamp system should be turned on when needed. To turn off the DRL, turn the exterior lamp control to the off position or shift into PARK (P). The DRL will stay off until the control is toggled again or the vehicle is shifted out of PARK (P). This procedure applies only to vehicles ﬁrst sold in the United States. Fog Lamps Use fog lamps for better vision in foggy or misty conditions. The fog lamps control is located on the multifunction lever next to the exterior lamp control. -(Fog Lamps): Turning the band to this position will turn the fog lamps on. When you turn the fog lamps on, the fog lamp light will appear on the instrument panel cluster to indicate that the fog lamps and the parking lamps are on. If you turn the high-beam headlamps on, the fog lamps will turn off. They will turn on again when you switch to low-beam headlamps. The ignition must be on for the fog lamps to operate. Some localities have laws that require the headlamps to be on along with the fog lamps. 3-17 Twilight Sentinel® Twilight Sentinel® can turn your lamps on and off for you. A light sensor on top of the instrument panel makes the Twilight Sentinel® work, so be sure it is not covered. With Twilight Sentinel®, you will see the following happen: (cid:129) When it is dark enough outside, the front turn signal lamps (DRL) will go off, and the headlamps and parking lamps will come on. The other lamps that come on with headlamps will also come on. (cid:129) When it is bright enough outside, the headlamps will go off, and the front turn signal lamps (DRL) will come on, as long as the exterior lamp switch is in the AUTO position. 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 about one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness control is in full bright position. See Instrument Panel Brightness on page 3-19. You can idle the vehicle with the lamps off, even when it is dark outside. After starting the vehicle, turn the exterior lamp control band on the multifunction lever to off and then release it. The lamps will remain off until you turn the control band to off again. Twilight Sentinel® also provides exterior illumination as you leave the vehicle. If Twilight Sentinel® has turned on the lamps when you turn off the ignition, your lamps will remain on until: The exterior lamp switch is moved from off to the parking lamp position, or (cid:129) A delay time that you select has elapsed. See “Personal Options” under DIC Vehicle Personalization on page 3-72 to select the delay time that you want. You can also select no delay time. If you turn off the ignition with the exterior lamp switch in the parking lamp or headlamp position, the Twilight Sentinel® delay will not occur. The lamps will turn off as soon as the switch is turned off. As with any vehicle, you should turn on the regular headlamp system when you need it. 3-18 (cid:129) Exterior Lighting Battery Saver If the manual parking lamps or headlamps have been left on, the exterior lamps will turn off as soon as the ignition is turned off or Retained Accessory Power (RAP) is active. This protects against draining the battery in case you have accidentally left the headlamps or parking lamps on. The battery saver does not work if the headlamps are turned on after the ignition switch is turned to off. If you need to leave the lamps on, use the exterior lamp control to turn the lamps back on. Instrument Panel Brightness The knob for this feature is located on the left side of the instrument panel. Push the knob in to turn on the interior lights. Turn and hold the knob clockwise to brighten the lights or counterclockwise to dim them. During the day, this knob will adjust the instrument panel brightness and at night will adjust all interior lighting. Be sure not to have this knob turned all the way down with the lamps on during the day. Your Driver Information Center (DIC) may not be visible. Courtesy Lamps When any door or the hatch/trunk lid is opened, the interior lamps will go on unless it is bright outside. You can also turn the courtesy lamps on and off by pressing the instrument panel brightness knob. Entry/Exit Lighting With entry lighting, the interior lamps will come on when entering the vehicle. The interior lamps will come on for about 20 seconds when the engine is off. You can turn exit and entry lighting off by quickly turning the courtesy lamps on and off. Reading Lamps The inside rearview mirror includes two reading lamps. The lamps will go on when a door is opened. When the doors are closed, each lamp can be turned on individually by pressing the switch for that lamp. An ambient light is located in the passenger sun visor clip. This light stays on while driving to keep the cabin from being too dark. 3-19 Battery Run-Down Protection This vehicle has a feature to help prevent the battery from being drained in case any of the following lamps are left on; the underhood lamp, if your vehicle has this feature, vanity mirror lamps, cargo lamps, reading lamps, console or glove box lamps. If any of these lamps are left on, they will automatically time-out after about 10 minutes. To reset it, all of the above lamps must be turned off or the ignition key on. Head-Up Display (HUD) {CAUTION: If the HUD image is too bright, or too high in your ﬁeld of view, it may take you more time to see things you need to see when it is dark outside. Be sure to keep the HUD image dim and placed low in your ﬁeld of view. The information may be displayed in English or metric units and appears as an image focused out toward the front of the vehicle. The HUD consists of the following information: (cid:129) Speedometer Turn Signal Indicators (cid:129) High-Beam Indicator Symbol Tachometer (cid:129) Manual Paddle Shift Gear Indicator (If Equipped) These displays on the HUD are for use when using the manual paddle shift controls to shift the transmission. See “Manual Paddle Shift” in Automatic Transmission Operation on page 2-26. (cid:129) Shift Light This light is used for performance driving to indicate that the vehicle’s best performance level has been reached to shift the transmission into the next higher gear. An arrow pointing up will light up on the display just prior to reaching the engine fuel cut-off mode. This cut-off is about 6,500 RPM for the LS3 engine and 7,000 RPM for the LS7 engine. If your vehicle has the Head-Up Display (HUD), you can see some of the driver information that appears on the instrument panel cluster. (cid:129) Check Gages Warning (cid:129) Engine Coolant Temperature Gage 3-20 (cid:129) (cid:129) Transmission Fluid Temperature Gage, (Automatic Transmission Vehicles Only) (cid:129) Engine Oil Temperature Gage (cid:129) Engine Oil Pressure Gage (cid:129) G-Force Gage (cid:129) Audio Functions, Street Mode Only (cid:129) Navigation, Only with Navigation Radio, Turn-by-Turn Guidance There are three HUD modes that you can choose to view in the HUD display. By pressing the MODE button, you can scroll through these modes in the following order: Street Mode supports audio and navigation functions with your choice of tachometer settings. Track Mode 1 supports the G-Force gage and minor gages with a circular tachometer. Track Mode 2 supports G-Force gages and minor gages with a linear tachometer. When the desired HUD display has been selected, release the MODE button. 3-21 (cid:129) Within each mode, the display, can be further customized by pressing the PAGE button. Pressing this button in each mode will turn off and on the following: (cid:129) Street Mode — No tachometer, circular tachometer, and linear tachometer. Track Modes 1 and 2 — No minor gage, coolant temperature, transmission oil temperature, engine oil temperature, and engine oil pressure. While in Track Mode 1 or 2, the maximum G value achieved during the current ignition cycle can be displayed by pressing and holding the PAGE button. The maximum G display will be shown until the PAGE button is released. The maximum G value display will be identical to the normal G value display, except the maximum G gage digits (X.XX G) and corresponding G gage bar will overwrite the current G value. 3-22 Be sure to continue scanning the displays, controls and driving environment just as you would in a vehicle without HUD. If you never look at your instrument panel cluster, you may miss something important, such as a warning light. Under important warning conditions, the CHECK GAGES warning will illuminate in the HUD. View your Driver Information Center (DIC) for more information. (cid:129) The HUD controls are located to the left of the steering wheel. 2. Adjust the seat to a comfortable driving position. If you change your seat position later, you may have to re-adjust your HUD. 3. Press the up or down arrows to center the HUD image in your view. The HUD image can only be adjusted up and down, not side-to-side. 4. Press the dimmer control downward until the HUD image is no brighter than necessary. To turn HUD off, press and hold the (–) button until the HUD display turns off. If the sun comes out or it becomes cloudy, you may need to adjust the HUD brightness again using the dimmer control.

The speedometer can be displayed in either English or Metric units. To change the language and unit selections, see “OPTION” under DIC Operation and Displays on page 3-50. Clean the inside of the windshield as needed to remove any dirt or ﬁlm that reduces the sharpness or clarity of the HUD image. 3-23 To adjust the HUD so you can see it properly, do the following: 1. Start the engine and press the HUD dimmer control all the way up by pressing the (+) button. The brightness of the HUD image is determined by the light conditions in the direction the vehicle is facing and where you have the HUD dimmer control set. If you are facing a dark object or a heavily shaded area, your HUD may anticipate that you are entering a dark area and may begin to dim. It is possible for sunlight to enter the HUD making it difficult to see the image. The display will return to normal when the sunlight is no longer entering the HUD. To clean the HUD, spray household glass cleaner on a soft, clean cloth. Wipe the HUD lens gently, then dry it. Do not spray cleaner directly on the lens because the cleaner could leak into the unit. If the ignition is on and you can not see the HUD image, check to see if: (cid:129) Something is covering the HUD unit. The HUD dimmer control is adjusted properly. The HUD image is adjusted to the proper height. (cid:129) Ambient light is low, in the direction your vehicle is facing. (cid:129) A fuse is blown. See Fuses and Circuit Breakers on page 5-96. Keep in mind that your windshield is part of the HUD system. See Windshield Replacement on page 5-55. Accessory Power Outlet(s) The accessory power outlet can be used to connect electrical equipment such as a cellular phone or CB radio. The accessory power outlet is located inside the center console storage compartment, on the forward left side. To use the outlet, remove the tethered cap. When not using it, always cover the outlet with the protective cap. 3-24 Notice: Leaving electrical equipment plugged in for an extended period of time while the vehicle is off will drain the battery. Power is always supplied to the outlets. Always unplug electrical equipment when not in use and do not plug in equipment that exceeds the maximum 20 ampere rating. Certain electrical accessories may not be compatible with the accessory power outlet and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer/retailer for additional information on accessory power outlets. 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 installation instructions included with the equipment. We recommend that you see a qualiﬁed technician or your dealer/retailer for the proper installation of your equipment. 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 (cid:129) (cid:129) Ashtray(s) and Cigarette Lighter The ashtray and cigarette lighter are located on the instrument panel, in front of the shift lever. To use the ashtray, press on the indentation at the top of the door. Notice: If you put papers, pins, or other 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. Loose objects, such as paper clips, can lodge behind and beneath the ashtray lid and prevent movement of the lid. You should avoid putting small, loose objects near the ashtray. To use the cigarette lighter, push it in all the way and let go. When it is 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 Dual Automatic Climate Control System With this system you can control the heating, cooling, and ventilation for your vehicle. When the vehicle is ﬁrst started, the display will show the driver’s temperature setting, the outside temperature, the fan speed and the air delivery, for about 10 seconds. The outside temperature is shown in the center of the display. The digital display will show the readings in Fahrenheit or Celsius. See “Personal Options” under DIC Vehicle Personalization on page 3-72 for information on changing your display. 3-25 Automatic Operation AUTO (Automatic): Press the AUTO button to place the entire system in the automatic mode. When automatic operation is active, the system will automatically control the inside temperature, the air delivery mode, and the fan speed. After a ten second display of the current settings, the word AUTO, the driver’s temperature setting and the outside temperature will be shown. The system will operate to achieve your comfort set temperature as quickly as possible. The AUTO control system works best with the windows up and the removable roof installed or the convertible top up. 1. Press the AUTO button. 2. Adjust the temperature to a comfortable setting between 60°F (16°C) and 90°F (32°C). Choosing the coldest or warmest temperature setting will not cause the system to heat or cool any faster. A setting of 73°F (23°C) is suggested. In cold weather, the system will start at reduced fan speeds to avoid blowing cold air into your vehicle until warmer air is available. The system will start out blowing air at the ﬂoor but may change modes automatically as the vehicle warms up to maintain the chosen temperature setting. The length of time needed for warm up will depend on the outside temperature and the length of time that has elapsed since your vehicle was last driven. 3-26 3. Wait for the system to regulate. This may take from 10 to 30 minutes. Then adjust the temperature, if necessary. Do not cover the solar sensor located in the center of the instrument panel, near the windshield. For more information on the solar sensor, see “Sensor” later in this section. Manual Operation Driver Power/Temperature: Press the driver temperature knob on the driver side of the climate control panel to turn the climate control system off. This is the only setting that completely shuts off the fan. The digital display will show only the outside temperature. You can still adjust the driver and the passenger set temperature and the air intake mode when the climate control is off. Passenger Power/Temperature: Press the passenger temperature knob on the passenger side of the climate control panel to turn the passenger’s climate control system on or off. Turn the knob to increase or decrease the temperature for the passenger. If the passenger’s climate control system is off, the driver’s temperature knob will control the temperature for the entire vehicle. N(MODE): Press this button to manually lock in the current air delivery setting and to stop the automatic mode control. Pressing the MODE button will delete AUTO from the digital display and the mode graphics will be shown. To change the setting, press the MODE button again. The AUTO button must be pressed to return to the automatic mode selection. To change the current mode, select one of the following: H(Vent): This mode directs most of the air to the instrument panel outlets, with a very small amount of air directed to the ﬂoor outlets. %(Bi-Level): This mode directs about half of the air to the instrument panel outlets, and directs the remaining air to the ﬂoor outlets. 6(Floor): This mode directs most of the air to the ﬂoor outlets with some air directed to the side window defogger outlets and some air directed toward the windshield. The MODE button can also be used to select the defog mode. Information on defogging and defrosting can be found later in this section. x 9 w(Fan): Press the button with the fan symbol to manually increase or decrease the fan speed. Keep pressing the up or down arrow on this switch until the desired fan speed appears on the display. Pressing the arrows will delete AUTO from the digital display. The fan graphics with the fan speed bars will be shown. To increase the fan speed so that more air ﬂows into the vehicle, press the up arrow on the fan switch. To decrease the fan speed and airﬂow, press the down arrow. The AUTO button must be pressed to return to the automatic fan control. If the airﬂow seems low when the fan speed is at the highest setting, the passenger compartment air ﬁlter may need to be replaced. For more information, see Passenger Compartment Air Filter on page 3-31 and Scheduled Maintenance on page 6-4. ?(Recirculation): Press this button to turn the recirculation mode on or off. When the climate control system is in recirculation mode an indicator light will come on. This mode prevents outside air from entering your vehicle. It can be used to prevent outside air and odors from entering your vehicle and to help cool the air inside your vehicle more quickly. Recirculation mode is not available in defrost or defog mode. ^(Air Conditioning Off): Press this button to turn the air conditioning compressor off. Press AUTO to return to automatic operation. When in AUTO, the air conditioning compressor will come on automatically, as needed. 3-27 Air conditioning does not operate at temperatures below about 35°F to 40°F (2°C to 4°C). In temperatures above 40°F (4°C), the air conditioning cannot be turned off in defrost and defog, as it helps to remove moisture from the vehicle. It also helps to keep the windows clear. You may notice a slight change in engine performance when the air-conditioning compressor shuts off and turns on again. This is normal. The system is designed to make adjustments to help with fuel economy while still maintaining the selected temperature. 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. For quick cool down on hot days press the AUTO button and adjust the temperature to a cool, comfortable setting. To achieve maximum cool down, do the following: 1. Select the vent mode. 2. Select recirculation mode. 3. Select the A/C on. 4. Select the coolest temperature. 5. Select the highest fan speed. Using these settings together for long periods of time may cause the air inside of your vehicle to become too dry. To prevent this from happening, after the air in your vehicle has cooled, turn the recirculation mode off. 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. Sensors The solar sensor on your vehicle monitors the solar radiation and uses the information to maintain the selected temperature when operating in AUTO mode by initiating needed adjustments to the temperature, the fan speed and the air delivery system. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be activated, as necessary. Do not cover the solar sensor located on the top of the instrument panel near the windshield or the system will not work properly. There is also a sensor located behind the front bumper. This sensor reads the outside air temperature and helps to maintain the temperature inside the vehicle. Any cover on the front of the vehicle could give a false reading in the temperature. 3-28 If the outside temperature goes up, the displayed temperature will not change until: The vehicle’s speed is above 12 mph (19 km/h) for ﬁve minutes. The vehicle’s speed is above 32 mph (52 km/h) for two and a half minutes. These delays prevent false readings. If the temperature goes down, the outside temperature will be shown when you start the vehicle. If it has been turned off for less than three hours, the temperature will be recalled from the previous vehicle operation. There is also an inside temperature sensor located to the left of the ignition switch. The automatic climate control system uses this sensor to receive information, so if you block or cover it, the system will not function properly. Defogging and Defrosting Fog on the inside of windows is a result of high humidity and 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 ﬂoor/defog mode to clear the windows of fog or moisture and warm the passengers. Use defrost to remove fog or frost from the windshield more quickly. To prevent fogging on the inside of the windows in modes other than ﬂoor/defog and defrost, make sure the air conditioning compressor is on and recirculation mode is off. Press the mode button until the defog mode appears on the display. -(Floor/Defog): This mode directs the air equally between the windshield and the ﬂoor outlets with a small amount to the side window outlets. When you select this mode, the system turns off recirculation and runs the air-conditioning compressor unless the outside temperature is at or below freezing. The recirculation mode cannot be selected while in the defog mode. 1(Defrost): Pressing this button directs most of the air to the windshield, with a small amount directed to the side window outlets. The light on the button will come on and the digital display will show the defrost mode symbol and fan speed when the front defrost mode is being used. In this mode, the system will automatically turn off the recirculation and run the air-conditioning compressor, unless the outside temperature is at or below freezing. Recirculation cannot be selected while in the defrost mode. Pressing this button again will return the system to the last operating mode. For severe ice conditions, turn the driver’s temperature knob to 90°F (32°C) while in defrost mode. Do not drive the vehicle until all the windows are clear. 3-29 (cid:129) (cid:129) 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. Outlet Adjustment Use the tab located on the air outlets to change the direction of the airﬂow. Operation Tips (cid:129) Clear away any ice, snow or leaves from the air inlets at the base of the windshield that may block the ﬂow of air into your vehicle. (cid:129) Use of non-GM approved hood deﬂectors may adversely affect the performance of the system. (cid:129) Keep the area around the base of the instrument panel console and air path under the seats clear of objects to help circulate the air inside of your vehicle more effectively. Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. The rear window defogger will only work when the engine is running. =(Rear Window Defogger): Press this button to turn the rear window defogger on. Be sure to clear as much snow from the rear window as possible. An indicator light in the button will come on to let you know that the rear window defogger is activated. The rear window defogger will turn off about 10 minutes after the button is pressed when traveling less than 30 mph (48 km/h). If turned on again, the defogger will only run for about ﬁve minutes before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. Your vehicle has heated outside rearview mirrors. The mirrors will heat to help clear fog or frost from the surface of the mirrors when the rear window defog button is pressed. If your vehicle has the power convertible top, the rear window defogger and heated mirrors are automatically disabled when the power convertible top is moving or down. 3-30 Passenger Compartment Air Filter The passenger compartment air ﬁlter removes certain particles from the air including pollen and dust particles. Reductions in airﬂow, which may occur more often in dusty areas, indicate that the ﬁlter may need to be replaced. See Scheduled Maintenance on page 6-4 for information on how often to replace the ﬁlter. Notice: Driving without a passenger compartment air ﬁlter in place can cause water and small particles, like paper and leaves, to be pulled into your climate control system which may cause damage to it. Make sure you always replace the old ﬁlter with a new one. The passenger compartment air ﬁlter is located on the passenger side of the engine compartment near the battery. See Engine Compartment Overview on page 5-14. To check or replace the air ﬁlter, do the following: 1. Undo the passenger compartment air ﬁlter housing cover retainer clips (A). 2. Remove the passenger compartment air ﬁlter housing cover. 3-31 expensive repair or replacement. Paying attention to your 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 you will see in the details 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 when 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 warning lights and gages. They are a big help. Your vehicle has a Driver Information Center that works along with the warning lights and gages. See Driver Information Center (DIC) on page 3-49. 3. Remove the passenger compartment air ﬁlter from the housing. 4. Insert the new ﬁlter into the housing. 5. Reinstall the passenger compartment air ﬁlter housing cover. 6. Attach the passenger compartment air ﬁlter housing cover retainer clips. Warning Lights, Gages, and Indicators This part describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them. Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an 3-32 Instrument Panel Cluster Your instrument panel cluster and Driver Information Center (DIC) are designed to let you know at a glance how the vehicle is running. You will know how fast you are going, about how much fuel you have left and many other things you will need to know to drive safely and economically. The instrument panel cluster indicator warning lights, gages and DIC messages are explained on the following pages. United States Manual Transmission shown, Canada, Automatic Transmission and Z06 Model similar 3-33 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. Speedometer and Odometer Your speedometer lets you see your speed in either miles per hour (mph) or kilometers per hour (km/h). For more information see “Personal Options” under DIC Vehicle Personalization on page 3-72. To read the odometer with the ignition off, turn on the parking lamps. If your vehicle needs a new odometer installed, the mileage total of the new odometer will be set to the original miles (kilometers) of the old odometer. See your dealer/retailer if the odometer must be replaced in your vehicle. Tachometer The tachometer displays the engine speed in thousands of revolutions per minute (rpm). Notice: Fuel will shut off at about 6500 rpm for the base model and 7000 rpm for the Z06 model. If you continue to drive your vehicle at the fuel shut off rpm, you could damage your engine. Be sure to operate your vehicle below the fuel shut off rpm or reduce your rpm quickly when the fuel shuts off. 3-34 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 1-44. 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. {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. 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 3-55 for more information. 3-35 Passenger Airbag Status Indicator Your vehicle has the passenger sensing system. Your rearview mirror has a passenger airbag status indicator. United States Canada 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 3-36 light either ON or OFF, or either the on or off symbol, to let you know the status to let you know the status of the right front passenger’s frontal and seat-mounted side impact airbags (if equipped). 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 and seat-mounted side impact airbag (if equipped) are enabled (may inﬂate). {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 and seat-mounted side impact airbag (if equipped). 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. {CAUTION: Even though the passenger sensing system is designed to turn off the right front passenger’s frontal airbag and seat-mounted side impact airbag (if equipped) 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 a rear seat, even if the airbag is or airbags are off. If the word OFF or the off symbol is lit on the passenger airbag status indicator, it means that the passenger sensing system has turned off the right front passenger’s frontal airbag and seat-mounted side impact airbag (if equipped). See Passenger Sensing System on page 1-52 for more on this, including important safety information. 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 3-35 for more on this, including important safety information. 3-37 Voltmeter Gage The voltmeter shows the voltage output of your battery. When the engine is running, it shows the voltage output of the charging system. One-to-Four Shift Light (Manual Transmission) When this light comes on, you can only shift from FIRST (1) to FOURTH (4) instead of FIRST (1) to SECOND (2). The reading will change as the rate of charge changes (with engine speed, for example), but if the voltmeter reads at 9 volts or below, your instrument panel cluster and other systems may shut down. The Driver Information Center (DIC) will read BATTERY VOLTAGE LOW when your vehicle is at 10 volts or below. Have it checked right away. Driving with the voltmeter reading at 10 volts or below could drain your battery and disable your vehicle. 3-38 You must complete the shift into FOURTH (4) to turn off this feature. This helps you get the best possible fuel economy. After shifting to FOURTH (4), you may downshift to a lower gear if you prefer. Notice: Forcing the shift lever into any gear except FOURTH (4) when the 1 TO 4 SHIFT light comes on may damage the transmission. Shift only from FIRST (1) to FOURTH (4) when the light comes on. This light will come on when: The engine coolant temperature is higher than 169°F (76°C), the vehicle is going 15 to 19 mph (24 to 31 km/h) and the vehicle 21 percent throttle or less. (cid:129) (cid:129) (cid:129) Brake System Warning Light 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. United States Canada This light should come on when you start the engine. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If this warning light stays on after you start the engine, the parking brake may still be set or there could be a brake problem. Refer to Parking Brake on page 2-34 to see if it is set. If the parking brake is not set, have your brake system inspected right away. If the light comes on while you are driving and you have a CHECK BRAKE FLUID message showing on the DIC, pull off the road and stop carefully. You may notice that the pedal is harder to push or the pedal 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 4-29 and DIC Warnings and Messages on page 3-55 for more information. {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. 3-39 Antilock Brake System Warning Light Traction Control System (TCS) Warning Light For vehicles with the Antilock Brake System (ABS), this light will come on brieﬂy when you start the engine. This light should come on brieﬂy as you start the engine. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. 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 3-39 For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-55 for all brake related DIC messages. 3-40 If it stays on, or comes on and the Driver Information Center (DIC) shows a SERVICE TRACTION SYSTEM message when you are driving, there is a problem with your Traction Control System (TCS) and your vehicle needs service. When this light is on, the system will not limit wheel spin. Adjust your driving accordingly. If the driver turns off the TCS by pressing the button on the console, the TCS light will come on and the TRACTION SYSTEM OFF message will show on the DIC. See DIC Warnings and Messages on page 3-55 for more information. Active Handling System Light The Active Handling System light will come on brieﬂy as you start the engine. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. This light will also come on when the ACTIVE HANDLING CALIBRATING message is displayed in the Driver Information Center (DIC). If the light stays on or comes on while you are driving, a chime sounds and a SERVICE ACTIVE HANDLING SYSTEM message appears on the DIC, there is a problem with your Active Handling System and your vehicle needs service.

When the SERVICE ACTIVE HANDLING SYSTEM message is displayed in the DIC, the Active Handling System will not assist you in controlling the vehicle. You should have the system serviced as soon as possible. Adjust your driving accordingly. 3-41 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. If the gage pointer moves into the shaded area, your engine is too hot. This means that your engine coolant has overheated. If you have been operating your vehicle under normal driving conditions, you should pull off the road, stop your vehicle and turn off the engine as soon as possible. See Engine Overheating on page 5-31 for more information. 3-42 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 3-55 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 5-58 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 5-68 for more information. 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. 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. Notice: this 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. If you keep driving your vehicle with 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. This light comes on brieﬂy, as a check to show it is working, as you start the engine. 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. 3-43 (cid:129) (cid:129) 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 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 engine 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. If the Light Is On Steady You might 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 5-8. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap allows fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. 3-44 Did you just drive through a deep puddle of water? If so, your vehicle’s electrical system might be wet. The condition is usually 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 5-5. Poor fuel quality causes the engine not to run as efficiently as designed. You might 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 might 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/retailer can check the vehicle. Your dealer/retailer has the proper test equipment and diagnostic tools to ﬁx any mechanical or electrical problems that might have developed. Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or might 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. To perform a check engine light bulb check with the keyless ignition, make sure the transmitter fob is in the passenger compartment. See Ignition Positions on page 2-22. Press the bottom of the Acc. button on the instrument panel and hold the button down for ﬁve seconds. The instrument panel, including the check engine light, will light up and the ignition will be on, but the engine will not start — if you press the bottom of the Acc. button only brieﬂy, less than ﬁve seconds, the accessory power mode will be turned on, but not the ignition. After the bulb check, be sure to press and release the Acc. button again to turn the ignition off and avoid draining the vehicle’s battery. 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 the battery or if the 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/retailer can prepare the vehicle for inspection. 3-45 Engine Oil Pressure Gage United States Canada United States — Z06 Model Canada — Z06 Model 3-46 The engine oil pressure gage shows the engine oil pressure in psi (pounds per square inch) or kPa (kilopascals) when the engine is running. Oil pressure should be 20 to 80 psi (140 to 550 kPa). In certain situations such as long, extended idles on hot days, it could read as low as 6 psi (40 kPa) and still be considered normal. It may vary with engine speed, outside temperature and oil viscosity, but readings above the shaded area show the normal operating range. Readings in the shaded area tell you that the engine is low on oil, or that you might have some other oil problem. See Engine Oil on page 5-17. The engine oil pressure can also be displayed using the GAGES button on the Driver Information Center (DIC). See Driver Information Center (DIC) on page 3-49. {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. Security Light Lights On Reminder For information regarding this light and the vehicle’s security system, see Theft-Deterrent System on page 2-18. This light comes on whenever the parking lamps are on. Fog Lamp Light The fog lamp light will come on when the fog lamps are in use. See Headlamps on Reminder on page 3-16 for more information. Highbeam On Light This light comes on when the high-beam headlamps are in use. The light will go out when the fog lamps are turned off. See Fog Lamps on page 3-17 for more information. See Headlamp High/Low-Beam Changer on page 3-9 for more information. 3-47 Here are ﬁve things that some owners ask about. All these things are normal and do not indicate that anything is wrong with the fuel gage. (cid:129) At the gas station, the gas pump shuts off before the gage reads the full symbol. It takes more (or less) fuel to ﬁll up than the gage reads. For example, the gage reads half full, but it took more (or less) than half of the tank’s capacity to ﬁt it. The gage pointer may move while cornering, braking or speeding up. The gage may not indicate the tank is empty when the ignition is turned off. The gage reading may change slightly within the ﬁrst several minutes after starting the vehicle. See DIC Operation and Displays on page 3-50 for more information. Fuel Gage Your fuel gage tells you about how much fuel you have left when the engine is on. When the needle approaches the low fuel symbol, a chime will sound and LOW FUEL will appear on the Driver Information Center (DIC) display. At this time, you still have a little fuel left, but you should get more soon. Press the RESET button to acknowledge a DIC message(s). Pressing the RESET button will also turn off a DIC message but the LOW FUEL message will come on again in 10 minutes if you have not added fuel to the vehicle. 3-48 (cid:129) (cid:129) (cid:129) (cid:129) Driver Information Center (DIC) The Driver Information Center (DIC) gives you the status of many of your vehicle’s systems. It is also used to display driver personalization features and warning/status messages. The DIC display is located on the instrument panel cluster below the speedometer and tachometer, directly above the steering column. The DIC buttons are located on the instrument panel, to the right of the instrument panel cluster. The DIC comes on when the ignition is turned on. After displaying CORVETTE BY CHEVROLET, the DIC will display the current driver and the information that was last displayed before the engine was turned off. If a problem is detected, a warning message will appear on the DIC display. Be sure to take any message that appears on the display seriously and remember that clearing the message will only make the message disappear, not correct the problem. If your vehicle has the Head-Up Display (HUD) and you use the Manual Paddle Shift feature, the gear will display in the HUD, except if your vehicle has the Navigation system and the HUD is displaying turn-by-turn guidance information. If the HUD is displaying turn-by-turn guidance information, the gear instead displays in the DIC. See “Manual Paddle Shift” under Automatic Transmission Operation on page 2-26 and “Head-Up Display (HUD)” in the index of the Navigation system manual for more information. 3-49 DIC Operation and Displays The Driver Information Center (DIC) has different modes which can be accessed by pressing the following buttons located on the instrument panel, to the right of the instrument panel cluster. 2(Gages): Press this button to display gage information like oil pressure and temperature, coolant temperature, automatic transmission ﬂuid temperature, if equipped, battery voltage, and front/rear tire pressures.
