2005 Chevrolet Corvette Coupe Owners Manual

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 don’t need to reset it. Once you’re going about 25 mph (40 km/h) or more, you can move the cruise control switch briefly from on to resume/accelerate. You’ll go right back up to your chosen speed and stay there. If you hold the switch at resume/accelerate the vehicle will keep going faster until you release the switch or apply the brake. So unless you want to go faster, don’t hold the switch at resume/accelerate.

3-12

Increasing Speed While Using Cruise Control There are two ways to go to a higher speed: (cid:127) 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’ll now cruise at the higher speed. If the accelerator pedal is held longer than 60 seconds, cruise control will turn off.

(cid:127) Move the cruise switch from on to

resume/accelerate. Hold it there until you get up to the speed you want, 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:127) 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’ll 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 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 may want to step on the accelerator pedal to maintain your speed. When going downhill, you may have to brake or shift to a lower gear to keep your speed down. Of course, applying the brake takes you out of cruise control. Many drivers find this to be too much trouble and don’t use cruise control on steep hills. 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. Stepping on the brake or clutch pedal will end the current cruise control session only. Move the cruise control switch to off to turn the system completely off.

3-13

(cid:127) Erasing Speed Memory When you turn off the cruise control or the ignition, your cruise control set speed memory is erased. 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): Turning the band to this position turns off all lamps.

3-14

AUTO (Automatic): Turning the band to this position sets the exterior lamps in automatic mode. AUTO mode will turn 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 will also reset when your vehicle is turned off and then back on again when 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:127) Sidemarker Lamps

Taillamps License Plate Lamps Instrument Panel Lights

The parking brake indicator light will come on and stay 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.

(cid:127) (cid:127) (cid:127) 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 will appear on the Driver Information Center (DIC). 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 off position and the transmission is not in PARK (P).

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. Your instrument panel will not be lit up either. When it is dark enough outside, the front turn signal lamps will turn off and normal low-beam headlamps will turn on.

3-15

(cid:127) (cid:127) (cid:127) 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.

When it is bright enough outside, the regular lamps will go off, and the front turn signal lamps will take over. If you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave the garage, it will take approximately one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness knob is in the full bright position. See Instrument Panel Brightness on page 3-18 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). This message informs the driver that turning on the exterior lamps is recommended. Turning the exterior lamp control to off a second time, or turning on the headlamps will remove the HEADLAMPS SUGGESTED message. If the parking lamps or the fog lamps were turned on instead, the HEADLAMPS SUGGESTED message will continue to be displayed. As with any vehicle, you should turn on the regular headlamp system when you need it.

3-16

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:127) 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:127) 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 3-18.

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 a delay time that you select has elapsed.

See “Personal Options” under DIC Vehicle Personalization on page 3-67 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.

3-17

(cid:127) (cid:127) 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 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.

Turn 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.

3-18

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 Your 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.

Battery Run-Down Protection Your vehicle has a feature to help prevent you from draining the battery in case the underhood lamp, vanity mirror lamps, cargo lamps, reading lamps, console or glove box lamps are accidentally left on. If you leave any of these lamps on, they will automatically time-out after about 20 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.

If your vehicle is equipped with the Head-Up Display (HUD), you can see some of the driver information that appears on your instrument panel cluster.

The information may be displayed in English or metric units and appears as an image focused out toward the front of your vehicle. The HUD consists of the following information: (cid:127) Speedometer

Turn Signal Indicators

(cid:127) High-Beam Indicator Symbol

Tachometer

(cid:127) Oil and Temperature Gages (cid:127) Shift Light (Performance 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. The SHIFT light will display at an engine speed of about 6,250 rpm, just prior to reaching the engine fuel cut-off mode.

When you have chosen the desired HUD display, release the MODE button. 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:127) 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.

If your vehicle is equipped with a navigation radio, many of the turn-by-turn navigation features will also be displayed on the HUD if you are in Street Mode.

3-20

(cid:127) Be sure to continue scanning your 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 not see 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.

The HUD controls are located to the left of the steering wheel.

To adjust the HUD so you can see it properly, do the following:

1. Start your 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 your 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.

3-21

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. Polarized sunglasses could make the HUD image harder to see. The HUD information can be displayed in one of six languages including English, Spanish, French, German, Italian or Japanese. The speedometer can be displayed in either English or Metric units. To change the language and unit selections, see “OPTION” under DIC Controls and Displays on page 3-48.

Clean the inside of the windshield as needed to remove any dirt or film that reduces the sharpness or clarity of the HUD image. 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’t see the HUD image, check to see if: (cid:127) Something is covering the HUD unit.

The HUD dimmer control is adjusted properly. The HUD image is adjusted to the proper height. (cid:127) Ambient light is low, in the direction your vehicle

is facing.

(cid:127) A fuse is blown. See Fuses and Circuit Breakers on

page 5-87.

Keep in mind that your windshield is part of the HUD system. If you ever have to have your windshield replaced, be sure to get one that is designed for HUD or your HUD image may look blurred and out of focus.

(cid:127) (cid:127) Accessory Power Outlets 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. Notice: Leaving electrical equipment on for extended periods will drain the battery. Always turn off electrical equipment when not in use and do not plug in equipment that exceeds the maximum amperage 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 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. Check with your dealer 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 for the proper installation of your equipment. Notice: cause damage not covered by your warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only.

Ashtrays 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: 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 will not allow the lighter to back away from the heating element when it is hot. Damage from overheating may occur to the lighter or heating element, or a fuse could be blown. Do not hold a cigarette lighter in while it is heating. Do not use anything other than the cigarette lighter in the heating element.

Climate Controls

Dual Automatic Climate Control System With this system you can control the heating, cooling and ventilation for your vehicle.

When your 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 3-67 for information on changing your display.

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. 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.

3-25

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. Cooler air is directed to the upper outlets and warmer air to the floor outlets. 6 (Floor): This mode directs most of the air to the floor outlets with some 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 3-30 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.

3-26

^ (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. 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.

3-27

If the outside temperature goes up, the displayed temperature will not change until:

The vehicle’s speed is above 10 mph (16 km/h) 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.

3-28

(cid:127) (cid:127) 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 is equipped with the power convertible top, the rear window defogger and heated mirrors are automatically disabled when the power convertible top is moving or down. Notice: Don’t use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs wouldn’t 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:127) 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:127) Use of non-GM approved hood deflectors may adversely affect the performance of the system. (cid:127) 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.

Passenger Compartment Air Filter The passenger compartment air filter removes certain odor and 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. The passenger compartment air filter is located on the passenger side of the engine compartment near the battery. See Engine Compartment Overview on page 5-12. To check or replace the air filter, do the following:

2. Remove the passenger compartment air filter

housing cover.

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. Engage the passenger compartment air filter

housing cover retainer clips.

1. Disengage the passenger compartment air filter

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 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 3-47.

3-31

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 shown, Canada similar

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 3-67. To read the odometer with the ignition off, turn on the parking lamps. You may wonder what happens 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 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 6600 rpm. 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.

Airbag Readiness Light There is an airbag readiness light on the instrument panel, which shows a deployed 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 modules, the wiring and the diagnostic module. For more information on the airbag system, see Airbag System on page 1-40.

This light will come on when you start your vehicle, and it will flash for a few seconds. Then the light should go out. This means 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 turn the vehicle on. If the light does not come on then, have it fixed so it will be ready to warn you if there is a problem.

3-34

Airbag Off Light When you turn off the passenger’s frontal airbag and side impact airbags (if equipped), an indicator on the center console will light and stay lit to remind you that the airbag or airbags have been turned off. This light will go off when you turn the airbag or airbags on. See Airbag Off Switch on page 1-48 for more on this, including important safety information.

{CAUTION:

If the passenger’s frontal airbag and side impact airbag (if equipped) are turned off for a person who is not in a risk group identified by the national government, that person will not have the extra protection of an airbag. In a crash, an airbag will not be able to inflate and help protect the person sitting there. Do not turn off the passenger’s frontal airbag and side impact airbag (if equipped) unless the person sitting there is in a risk group. See Airbag Off Switch on page 1-48 for more on this, including important safety information.

{CAUTION:

If the airbag readiness light ever comes on when you have turned off the passenger’s frontal airbag and side impact airbag (if equipped), it means that something may be wrong with the airbag system. The passenger’s frontal airbag and side impact airbag (if equipped) could inflate even though the switch is off. If this ever happens, do not let anyone whom the national government has identified as a member of a passenger airbag risk group sit in the passenger’s position (for example, do not secure a rear-facing child restraint in your vehicle) until you have your vehicle serviced. See Airbag Off Switch on page 1-48.

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.

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.

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 4-37.

{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.

Anti-Lock Brake System Warning Light

With the anti-lock brake system, the light will come on when your engine is started and may stay on for several seconds. That is normal.

If the light stays on, turn the ignition off. Or, if the light comes on when you are driving, stop as soon as possible and turn the ignition off. Then start the engine again to reset the system. If the 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 anti-lock brakes. If the regular brake system warning light is also on, you do not have anti-lock brakes and there is a problem with your regular brakes. See “SERVICE ANTILOCK BRAKES” under DIC Warnings and Messages on page 3-53. The anti-lock brake system warning light will come on briefly when you turn the ignition on. This 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.

Engine Coolant Temperature Gage

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 5-25 for more information.

Tire Pressure Light

This light should come on briefly as you start the engine. It will then come on only when a flat or low tire pressure condition exists.

See Tire Pressure Monitor System on page 5-61 for more information.

Malfunction Indicator Lamp Check Engine Light

Your vehicle is equipped with a computer which monitors operation of the fuel, ignition, and emission control systems.

If you keep driving your vehicle with this

This system is called OBD II (On-Board Diagnostics-Second Generation) and is intended to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The CHECK ENGINE light comes on to indicate that there is a problem and service is required. Malfunctions often will be indicated by the system before any problem is apparent. This may prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction. Notice: light on, after awhile, your emission controls may not work as well, your fuel economy may not be as good, and your engine may not run as smoothly. This could lead to costly repairs that may 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 may cause this light to come on. Modifications to these systems could lead to costly repairs not covered by your warranty. This may also result in a failure to pass a required Emission Inspection/Maintenance test.

3-41

This light should come on briefly, as a check to show you it is working, as you start the engine. If the light does not come on, have it repaired. This light will also come on during a malfunction in one of two ways:

Light Flashing — A misfire condition has been detected. A misfire increases vehicle emissions and may damage the emission control system on your vehicle. Diagnosis and service may be required. Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service may be required.

If the Light Is Flashing The following may prevent more serious damage to your vehicle: (cid:127) Reducing vehicle speed (cid:127) Avoiding hard accelerations (cid:127) Avoiding 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 your 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 for service as soon as possible. If the Light Is On Steady You also may be able to correct the emission system malfunction by considering the following: Did you recently put fuel into your vehicle? If so, reinstall the fuel cap, making sure to fully install the cap. See Filling Your Tank on page 5-7. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. Did you just drive through a deep puddle of water? If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off.

3-42

(cid:127) (cid:127) 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 will cause your engine not to run as efficiently as designed. You may notice this as stalling after start-up, stalling when you put the vehicle into gear, misfiring, hesitation on acceleration, or stumbling on acceleration. (These conditions may go away once the engine is warmed up.) This will be detected by the system and cause the light to turn on. If you experience one or more of these conditions, change the fuel brand you use. It will require at least one full tank of the proper fuel to turn the light off. If none of the above steps have made the light turn off, your dealer can check the vehicle. Your dealer has the proper test equipment and diagnostic tools to fix any mechanical or electrical problems that may have developed.

Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. Here are some things you need to know to help your vehicle pass an inspection: Your vehicle will not pass this inspection if the CHECK ENGINE light is on or not working properly. 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 2-20. 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 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.

3-43

Engine Oil Pressure Gage

Your vehicle will not pass this inspection if the OBD (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if you have recently replaced your battery or if your battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This may take several days of routine driving. If you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, your GM dealer can prepare the vehicle for inspection.

United States

Canada

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 5-14.

3-44

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 3-47.

Security Light

{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.

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.

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:127) 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 Controls and Displays on page 3-48 for more information.

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.
