2006 Cadillac CTS Owners Manual

The windshield washer button is located at the end of the windshield wiper lever. K (Washer Fluid): Press the button with this symbol located at the end of the windshield washer lever to wash the windshield. Washer fluid will spray onto the windshield and the wipers will run for a few cycles to clear the windshield. For more wash cycles, press and hold the button.

If your vehicle is low on washer fluid, the Check Washer Fluid message will appear on the Driver Information Center (DIC) display. See DIC Warnings and Messages on page 3-61.

If the headlamps are on when you wash the windshield, the headlamp washers (if equipped) will turn on. Both the windshield and the headlamps will be washed. See “Headlamp Washer” following for more information.

3-12

Headlamp Washer If your vehicle has the high-intensity discharge (HID) headlamps, your vehicle will also have headlamp washers. The headlamp washers help clear the headlamp lenses.

The headlamp washers are located on the inboard side of the headlamp lenses.

The headlamps must be on in order to be washed. If the headlamps are off, only the windshield will be washed when the washer button is pressed. To wash the headlamps, press the washer button located at the end of the windshield wiper lever. Both the headlamps and the windshield will be washed. See Windshield Washer on page 3-12 for more information.

Cruise Control

If you apply your brakes, the cruise control will shut off.

These controls are located on the end of the multifunction lever.

{CAUTION:

9(Off): This position turns the system off. R(On): This position turns the system on. + (Resume/Accelerate): Push the lever to this symbol to make the vehicle resume to a previously set speed or to accelerate when cruise is already active. T(Set/Decrease): Press this button to set the speed or to decrease the speed when cruise is already active. 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 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 needless wheel spinning, and you could lose control. Do not use cruise control on slippery roads.

If your vehicle is in cruise control when the traction control system begins to limit wheel spin, the cruise control will automatically disengage. See Traction Control System (TCS) (CTS) on page 4-9 or Traction Control System (TCS) (CTS-V) on page 4-10 and StabiliTrak® System on page 4-12. When road conditions allow you to safely use it again, you may turn the cruise control back on.

3-13

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.

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 you want. 3. Press in the set button at the end of the lever and

release it.

4. Take your foot off the accelerator pedal.

This light on the instrument panel cluster will come on while cruise control is on.

3-14

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.

(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.

If using the accelerator pedal and the set button at end of the lever to increase cruise set speed, your new set speed must be at least 5 mph higher than current speed for this method to work. If it is not 5 mph higher, switch cruise switch off, then on, and then reset your speed using the set button.

Reducing Speed While Using Cruise Control There are two ways to reduce your speed while using cruise control: (cid:127) Press in the button at the end of the lever 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.

3-15

(cid:127) Using Cruise Control on Hills How well your cruise control will work on hills depends upon your speed, load and the steepness of the hills. When going up steep hills, you may have to step on the accelerator pedal to maintain your speed. When going downhill, you may have to brake or shift to a lower gear to keep your speed down. Applying the brake or shifting into a lower gear will take you out of cruise control. If you need to apply the brake or shift to a lower gear due to the grade of the downhill slope, you may not want to attempt to use your cruise control feature. 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 end a cruise control session also. Stepping on the brake or clutch pedal will end the current cruise control session only. Move the cruise control switch to off to turn off the system completely. Erasing Speed Memory When you turn off the cruise control or the ignition, your cruise control set speed memory is erased.

3-16

Headlamps The exterior lamp control is located in the middle of the turn signal/multifunction lever. See Turn Signal/Multifunction Lever on page 3-9. O(Exterior Lamp Control): Turn the control with this symbol on it to operate the exterior lamps. The exterior lamp control has the following four positions: 9 (Off): Turning the control to this position turns off all lamps except the Daytime Running Lamps (DRL). ; (Parking Lamps): Turning the control to this position turns on the parking lamps together with the following: (cid:127) Sidemarker Lamps

Taillamps License Plate Lamps Instrument Panel Lights

5 (Headlamps): Turning the control to this position turns on the headlamps, together with the previously listed lamps and lights. AUTO (Automatic): Turning the control to this position puts the headlamps in automatic mode. AUTO mode will turn the exterior lamps on and off depending upon how much light is available outside of the vehicle.

(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 about six seconds. For this feature to work, the exterior lamp control must be in AUTO. When the exterior lamp control is off or in the parking lamp position and the windshield wiper control is in any position except off, the Headlamps Suggested message will appear on the DIC display. See “Headlamps Suggested Message” under DIC Warnings and Messages on page 3-61 for more information. When the ignition is turned to OFF, the wiper-activated headlamps will immediately turn off. They will also turn off if the windshield wiper control is turned 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. See Lights On Reminder on page 3-45 for additional information.

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 turn signal lamps come on when the following conditions are met:

It is still daylight and the ignition is in ON or START, the exterior lamp control is in off or AUTO with the headlamps off, and an automatic transmission is not in PARK (P) or the parking brake is not set on a manual transmission. When DRL are on, only your front turn signal lamps will be on. No other exterior lamps will be on when the DRL are being used. Your instrument panel won’t be lit up either.

3-17

(cid:127) (cid:127) (cid:127) When the exterior lamp control is in AUTO and it’s dark enough outside, the DRL will turn off and the low-beam headlamps will turn on. When it’s bright enough outside, the low-beam headlamps will go off, and the DRL will turn back on. 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 lever is in the full bright position. See Instrument Panel Brightness on page 3-20. If it’s dark enough outside and the exterior lamp control is off, a Headlamps Suggested message will appear on the Driver’s Information Center (DIC) display. This message informs the driver that turning on the exterior lamps is recommended even though the DRL are still illuminated. Turning the exterior lamp control to

AUTO or to the low-beam headlamp position will turn off the DRL and cancel the Headlamps Suggested message. If the parking lamps or the fog lamps were turned on instead, the DRL will still turn off and the Headlamps Suggested message will be displayed. You can turn it off by pressing the OK button if you have the Navigation audio system or the CLR button if you have the Base audio system. To operate your vehicle with the DRL off, turn the exterior lamp control off. Then turn on the fog lamps or parking lamps, and the DRL will turn off. The Headlamps Suggested message will appear on the DIC display. This will work regardless of gear position and whether or not the parking brake is set. As with any vehicle, you should turn on the regular headlamp system when you need it.

3-18

Light Sensor

The light sensor for the DRL and AUTO headlamp feature is located on top of the instrument panel. If you cover the sensor, it will read dark, and the exterior lamps or the Headlamps Suggested message will appear on the DIC whenever the ignition is on.

Fog Lamps Use the fog lamps for better vision in foggy or misty conditions. The fog lamp control is located on the turn signal/multifunction lever. - (Fog Lamps): The band with/or next to this symbol is used to turn the fog lamps on and off. The parking lamps must be on for the fog lamps to work. To operate the fog lamps:

To turn the fog lamps on, turn the fog lamp band on the lever up to the dot and release it. The band will return to its original position. To turn the fog lamps off, turn the for lamp band up to the dot and release it. The band will return to its original position, and the fog lamps will turn off. If you turn on the high-beam headlamps, the fog lamps will also turn off. They’ll turn back on again when you switch back to low-beam headlamps.

Some localities have laws that require the headlamps to be on along with the fog lamps.

3-19

(cid:127) (cid:127) Exterior Lighting Battery Saver If the parking lamps or headlamps have been left on, the exterior lamps will turn off about 10 minutes after the ignition is turned to OFF. 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 is turned to OFF. If you need to leave the lamps on for more than 10 minutes, use the exterior lamp control to turn the lamps back on.

Instrument Panel Brightness

The lever for this feature is located on the overhead console.

Slide the lever toward the symbol to brighten the lights or away from it to dim them. If you slide the lever all the way toward the symbol past the resistance point, the interior lamps will come on. To turn them off, slide the lever back toward the minimum brightness setting.

3-20

Entry Lighting The entry lighting system turns on the reading and dome lamps and the backlighting to the exterior lamp control when a door is opened or if you press the remote keyless entry transmitter unlock button. If activated by the transmitter, the lighting will remain active for about 25 seconds. The entry lighting system uses the light sensor; it must be dark outside in order for the lamps to turn on. The lamps turn off about 25 seconds after the last door is closed. They will dim to off if the ignition key is turned to ON, or immediately deactivate if the power locks are activated.

Parade Dimming This feature prohibits dimming of the instrument panel displays and backlighting during daylight hours when the key is in the ignition and the headlamps are on. This feature operates with the light sensor and is fully automatic. When the light sensor reads darkness outside and the parking lamps are active, the instrument panel displays can be adjusted by sliding the instrument panel brightness lever toward the symbol to brighten or away from the symbol to dim the lighting.

Reading Lamps The reading lamps are located on the overhead console. These lamps come on automatically when any door is opened. For manual operation, press the button next to each lamp to turn it on. Press it again to turn the lamp off. If the reading lamps are left on, they automatically shut off 10 minutes after the ignition has been turned off.

Accessory Power Outlet(s) With accessory power outlets, you can plug in auxiliary electrical equipment such as a cellular telephone or CB radio. The front accessory power outlet is located in the ashtray on the instrument panel below the climate control system. The outlet will have a cigarette lighter if your vehicle has this option. Remove the cigarette lighter to access the outlet. The rear accessory power outlet is located on the back of the center console. The power outlets can be set to be powered all of the time or to turn off 10 minutes after your vehicle is shut off. If you desire a change from this setting, see your dealer for a fuse adjustment.

3-21

Ashtray(s) and Cigarette Lighter Your vehicle may have an ashtray and cigarette lighter. 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. Ashtray The ashtray is located under the climate control panel on the instrument panel. Press on the door to release the ashtray. To empty the ashtray, remove it from the instrument panel by gripping the edges and pulling straight out. To reinstall, push the tray back into place.

Your vehicle may have a small cap that must be removed to access the accessory power outlet. If it does, when not using the outlet be sure to cover it 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. Do not use equipment exceeding maximum amperage rating. Check with your dealer before adding electrical equipment. When adding electrical equipment, be sure to follow the proper installation instructions included with the electrical equipment you install. 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

Automatic Operation

AUTO (Automatic): When this button is pressed and the temperature is set, the system will automatically control the inside temperature, the air delivery mode, the air conditioning compressor and the fan speed. AUTO will appear on the display. 1. Press the AUTO button. 2. Adjust the temperature to a comfortable setting

between 70°F (21°C) and 80°F (27°C). Choosing the coldest or warmest temperature setting will not cause the system to heat or cool any faster. If you set the system at the warmest temperature setting, the system will remain in manual mode at that temperature and it will not go into automatic mode. 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.

3-24

You can switch from English to metric units through the Driver Information Center (DIC). If you have the Base audio system, see DIC Main Menu on page 3-57. If you have the Navigation system, see “Setup Menu” in the Index of the CTS/CTS-V Navigation System Owner Manual. 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. 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 “Sensors” later in this section. Manual Operation yN z (Mode): Pressing the mode switch and changing the mode cancels automatic operation and places the system in manual mode. Press AUTO to return to automatic operation.

The outboard air outlets will always receive airflow regardless of the mode selected. See Outlet Adjustment on page 3-28 to change this airflow from the outboard outlets.

To change the current mode, select one of the following: Y (Vent): This mode directs air to the instrument panel outlets. \ (Bi-Level): This mode directs approximately half of the air to the instrument panel outlets, and then directs most of the remaining air to the floor outlets. In automatic operation, cooler air is directed to the upper outlets and warmer air to the floor outlets. [ (Floor): This mode directs most of the air to the floor outlets with some air directed to the outboard outlets (for the side windows), and a little air directed to the windshield.

The mode switch can also be used to select the defog mode. Information on defogging and defrosting can be found later in this section. yAz (Fan): Press this switch to increase or decrease the fan speed. Pressing this switch cancels automatic operation and places the system in manual mode. Press AUTO to return to automatic operation.

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 3-29
and Scheduled Maintenance on page 6-4.

h (Recirculation): This mode keeps outside air from coming in the vehicle. It can be used to prevent outside air and odors from entering your vehicle or to help heat or cool the air inside your vehicle more quickly. Press this button to turn the recirculation mode on or off. The air-conditioning compressor also comes on. After manually selecting recirculation, the auto button must be pressed to enable the system to select the optimum air delivery setting for the vehicle.

Recirculation is not available in the defog or defrost mode and will automatically turn off after 10 minutes when defog is selected.

Using recirculation for long periods of time may cause the air inside your vehicle to become too dry or stuffy. To prevent this from happening, after the air in your vehicle has cooled, turn the recirculation mode off or press the auto button. QPWRR (Power/Driver’s Temperature): Press the PWR button located on the driver’s side of the climate control panel to turn the entire climate control system on or off. Press the up or down arrow on the switch to increase or decrease the temperature inside your vehicle.

QPWRR (Power/Passenger’s Temperature): Press the PWR button located on the passenger’s side of the climate control panel to allow the passenger’s climate control setting to be different than the driver’s. Press the up or down arrow on the switch to increase or decrease the temperature for the front passenger. A/C OFF (Air Conditioning): Press this button to manually turn off the air conditioning compressor. Press AUTO to return to automatic operation or press the A/C OFF button again. Sensors

There is also an interior temperature sensor located to the right of the steering wheel on the instrument panel.

These sensors monitor the solar radiation and the air inside your vehicle, then use the information to maintain the selected temperature 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 sensors or the automatic climate control system will not work properly.

There is a solar sensor located on the instrument panel, near the windshield.

3-26

Defogging and Defrosting Fog on the inside of windows is a result of high humidity (moisture) condensing on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to clear fog from your windshield. Use the defog mode to clear the windows of fog or moisture and warm the passengers. Use the defrost mode to remove fog or frost from the windshield more quickly. yN z (Mode): Press this button until defog appears on the display. - (Defog): This mode directs the air between the windshield, floor outlets and side windows. 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 is cancelled when you enter defog mode. If you select recirculation while in defog mode, it will be cancelled after 10 minutes.

If you have fogging on the side windows, turn the thumbwheel on the outboard outlets to the side window defog position. See Outlet Adjustment on page 3-28
for more information.

0 (Defrost): Pressing defrost directs most of the air to the windshield, with some air directed to the side windows. In this mode, the system will automatically turn off 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.

This mode may also cause the fan speed and air temperature to increase.

If you have fogging on the side windows, turn the thumbwheel on the outboard outlets to the side window defog position. See Outlet Adjustment on page 3-28
for more information. Do not drive the vehicle until all the windows are clear. Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. The rear window defogger will only work when the ignition is in ON.

3-27

= (Rear Window Defogger): Press this button to turn the rear window defogger on or off. Be sure to clear as much snow from the rear window as possible. The rear window defogger will turn off about 10 minutes after the button is pressed, but if the vehicle’s speed is above 30 mph (48 km/h), the rear defogger will stay on continuously. 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. The heated outside rearview mirrors will heat to help clear fog or frost from the surface of the mirror when the rear window defogger button is on. Notice: Do not try to clear frost or other material from the inside of the front windshield and rear window with a razor blade or anything else that is sharp. This may damage the rear window defogger grid and affect your radio’s ability to pick up stations clearly. The repairs wouldn’t be covered by your warranty.

Outlet Adjustment Use the knobs located in the center of each outlet to change the direction of the airflow. Use the thumbwheels to open or close the outlets.

3-28

j (Side Window Defog): Turn the thumbwheel to this symbol to use the side window defog setting. The air coming through the outlets will be directed toward the side windows to clear fog. k (Open): Turn the thumbwheel to this symbol to open the outlets completely and allow the maximum amount of air to enter your vehicle. A small amount of air will still be directed to the side windows. l (Closed): Turn the thumbwheel to this symbol to close the outlets and minimize the amount of air entering the vehicle. 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 path under the front seats clear of objects to help circulate the air inside of your vehicle more effectively. 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 3-29.

(cid:127) Passenger Compartment Air Filter The passenger compartment air filter traps most of the pollen from the air entering your vehicle. Like your vehicle’s engine air cleaner/filter, it needs to be changed periodically. For how often to change the passenger compartment air filter, see Scheduled Maintenance on page 6-4. Using your climate control system without the passenger air filter installed may allow water or other debris to enter the system. This could cause a water leak or noises. Make sure to install a new air filter after removing the old one.

The passenger compartment air filter is located underneath the hood below the windshield wiper arm on the passenger’s side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location.

Use the procedure listed below to replace the passenger compartment air filter: 1. Turn the ignition to ON with the engine off. 2. Turn on the windshield wipers and turn them off again when the wipers are straight up and down on the windshield. This will allow you access to the leaf screen under which is located the passenger compartment air filter. 3. Open the hood to access the engine compartment.

See Hood Release on page 5-11 for more information.

4. Remove the four screws that hold the leaf screen in place and lift off the screen by lifting and sliding toward the center of the vehicle.

5. Pull out on the two tabs located on each end of the

filter cover.

6. Lift the filter cover off by pulling it straight upward. 7. Remove the old filter and insert a new one.

Make sure the arrow on the filter is pointing toward the passenger compartment. See Normal Maintenance Replacement Parts on page 6-15 for the correct part number for the filter.

8. Reverse Steps 1 through 6 to reinstall the cover.

Steering Wheel Climate Controls (CTS) Your vehicle may have four controls that can be programmed for use with the climate control system.

The controls are located on the left side of the steering wheel.

See Reconfigurable Steering Wheel Controls (SWC) (CTS) on page 3-7 for more information on programming these controls. 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.

3-30

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’re 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’s 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. 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’re a big help. Your vehicle also has a Driver Information Center (DIC) that works along with the warning lights and gages. See Driver Information Center (DIC) on page 3-53 for more information.

Instrument Panel Cluster The instrument panel cluster is designed to let you know at a glance how your vehicle is running. You will know how fast you are going, how much fuel you are using and many of the other things you will need to know to drive safely and economically.

Speedometer and Odometer The speedometer lets you see your speed in either miles per hour (mph) or kilometers per hour (km/h). The odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). If your vehicle has to have a new odometer installed, the new one may read the correct mileage. This is because your vehicle’s computer has stored the mileage in memory. While the Driver Shift Control (DSC) feature is active, the odometer will change to show the gear range. See Automatic Transmission Operation on page 2-26 for more information.

Trip Odometers The trip odometer can record the number of miles or kilometers traveled for up to two trips. The trip odometer is part of the Driver Information Center (DIC), for more information see Status of Vehicle Systems on page 3-54. For vehicles equipped with the navigation system, see your Navigation System manual for more information.

Tachometer This gage indicates the engine speed in revolutions per minute (rpm). Notice: tachometer in the shaded warning area, your vehicle could be damaged, and the damages would not be covered by your warranty. Do not operate the engine with the tachometer in the shaded warning area.

If you operate the engine with the

Engine Speed Limiter This feature prevents the engine from operating at too many revolutions per minute (rpm). When the engine’s rpms are too high, the throttle is closed to reduce speed. If this is not sufficient, then the fuel supply to the engine will be limited. When the rpms return to normal, the fuel supply will return to normal. This helps prevent damage to the engine.

3-33

Safety Belt Reminder Light When the key is turned to ON or START, 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.

If the driver’s belt is already buckled, the chime will not come on.

Airbag Readiness Light There is an airbag readiness light on the instrument panel, which shows the airbag symbol. The system checks the airbag’s electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the airbag sensors, the airbag modules, the wiring and the diagnostic module. For more information on the airbag system, see Airbag System on page 1-50.

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.

3-34

{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 ignition key to ON. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem. If there is a problem with the airbag system in your vehicle, the Service airbag message will appear on the DIC display. See DIC Warnings and Messages on page 3-61 for more information.

Passenger Airbag Status Indicator Your rearview mirror has a passenger airbag status indicator.

When the ignition key is turned to ON or START, the passenger airbag status indicator will light ON and OFF, or the symbol for on and off, for several seconds as a system check. Then, after several more seconds, the status indicator will light either ON or OFF, or either the on or off symbol to let you know the status of the right front passenger’s frontal airbag.

3-35

If the word ON or the on symbol is lit on the passenger airbag status indicator, it means that the right front passenger’s frontal airbag is enabled (may inflate).

{CAUTION:

{CAUTION:

If the on indicator comes on when you have a rear-facing child restraint installed in the right front passenger’s seat, it means that the passenger sensing system has not turned off the passenger’s frontal airbag. A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. Do not use a rear-facing child restraint in the right front passenger’s seat if the airbag is turned on.

Even though the passenger sensing system is designed to turn off the passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is failsafe, and no one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. We recommend that rear-facing child restraints be secured in the rear seat, even if the airbag is off.

If the word OFF or the off symbol is lit on the airbag status indicator, it means that the passenger sensing system has turned off the right front passenger’s frontal airbag. See Passenger Sensing System on page 1-60
for more on this, including important safety information.

Your vehicle has a rear seat that will accommodate a rear-facing child restraint. A label on your sun visor says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the airbag deploys.

3-36

If, after several seconds, all status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer for service.

{CAUTION:

If the off indicator and the airbag readiness light ever come on together, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger seat may not have the protection of the frontal airbag. See Airbag Readiness Light on page 3-34.

Charging System Light

When you turn the key to ON or START, this light will come on briefly to show that the generator and battery charging systems are working properly.

If this light stays on, your vehicle needs service. You should take your vehicle to the dealer at once. To save your battery until you get there, turn off all accessories. For more information see DIC Warnings and Messages on page 3-61.

3-37

Brake System Warning Light Your vehicle’s hydraulic brake system is divided into two parts. If one part isn’t working, the other part can still work and stop you. For good braking, though, you need both parts working well. If the warning light comes on, there is a brake problem. Have your brake system inspected right away.

United States

Canada

This light should come on briefly when you turn the ignition key to ON. If it doesn’t come on then, have it fixed so it will be ready to warn you if there’s a problem.

When the ignition is on, the brake system warning light will also come on when you set your parking brake. The light will stay on if your parking brake doesn’t release fully. If it stays on after your parking brake is fully released, it means you have a brake problem. If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push, or 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.

3-38

Anti-Lock Brake System Warning Light

Traction Control System (TCS) 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 TC (traction control) warning light comes on and stays on, there may be a problem with the traction control system.

If the ABS warning light comes on and stays on, there may be a problem with the anti-lock portion of the brake system. If the red BRAKE light is not on, you still have brakes, but you do not have anti-lock brakes. See Brake System Warning Light on page 3-38. If the light stays on, turn the ignition to OFF. 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 Brake System Warning Light on page 3-38.

The TC (traction control) warning light will come on briefly when you turn the ignition to ON. If it doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem. The light will also come on if you turn the traction control system off using the TC (traction control) on/off button located in the glove box for the CTS and on the steering wheel for the CTS-V. If the TC (traction control) warning light stays on or comes on while you are driving, pull off the road as soon as possible and stop carefully. Try resetting the system by turning the ignition off then back on. If the light still stays on or comes back on again while you are driving, your vehicle needs service. Have the traction control system inspected as soon as possible. See Traction Control System (TCS) (CTS) on page 4-9 or Traction Control System (TCS) (CTS-V) on page 4-10
for more information.

3-39

Engine Coolant Temperature Warning Light (CTS)

This light tells you that your engine is very hot.

Engine Coolant Temperature Gage

This gage shows the engine coolant temperature. If the gage pointer moves into the shaded area, the engine is too hot.

That reading means the same thing as the warning light – the engine coolant is very hot. See Engine Overheating on page 5-30.

This light will come on when you first start the vehicle as a check to let you know that the light is working. It will go out after a few seconds. If the light does not come on, the bulb may be burned out. See your dealer for assistance in changing the bulb. If the light does not go out or if the light comes on and stays on while you are driving, your vehicle may have a problem with the cooling system. You should stop the vehicle and turn off the engine as soon as possible to avoid damage to the engine. A warning chime will sound when this light is on, also. See Engine Overheating on page 5-30 and Message Center (CTS-V) on page 3-47 for more information.

3-40

Tire Pressure Light

If equipped, this light will come on if the system detects low tire pressure.

This light will also come on for a bulb check when the vehicle is started. See Tire Pressure Monitor System on page 5-69 for more information. For more information on the proper tire pressure, see Loading Your Vehicle on page 4-32. For more information on your tires, see Tires on page 5-58.

Malfunction Indicator Lamp Check Engine Light

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

This system is called OBD II (On-Board Diagnostics-Second Generation) and is intended to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The check engine light comes on to indicate that there is a problem and service is required. Malfunctions often will be indicated by the system before any problem is apparent. This may prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction. Notice: If you keep driving your vehicle with this 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.

3-41

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 you are towing a trailer, reduce the amount of cargo being hauled as soon as it is possible If the light stops flashing and remains on steady, see “If the Light Is On Steady” following. If the light continues to flash, when it is safe to do so, stop the vehicle. Find a safe place to park your vehicle. Turn the key off, wait at least 10 seconds and restart the engine. If the light remains on steady, see “If the Light Is On Steady” following. If the light is still flashing, follow the previous steps, and see your dealer for service as soon as possible.

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. See Accessories and Modifications on page 5-3. This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If the light does not come on, have it repaired. This light will also come on during a malfunction in one of two ways:

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.

3-42

(cid:127) (cid:127) (cid:127) If the Light Is On Steady You may be able to correct the emission system malfunction by considering the following: Did you recently put fuel into your vehicle? If so, reinstall the fuel cap, making sure to fully install the cap. See Filling the Tank on page 5-8. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. Did you just drive through a deep puddle of water? If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off. Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See Gasoline Octane on page 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.

3-43

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.

Oil Pressure 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.

If equipped, this light tells you if there could be a problem with your engine oil pressure.

The light goes on when you turn your key to ON or START. It goes off once you start your engine. That’s a check to be sure the light works. If it doesn’t come on, be sure to have it fixed so it will be there to warn you if something goes wrong. When the light comes on and stays on, it means that oil isn’t flowing through your engine properly. You could be low on oil and you might have some other system problem. See Engine Oil on page 5-16 for more information.

3-44

Sport Mode Light (Automatic Transmission/CTS)

Fog Lamp Light

This light will come on while the sport mode is in use.

This light will come on when the fog lamps are in use.

When you turn off the sport mode, the light will go out. If it stays on, your vehicle may need service. See your dealer. See “Sport Mode” under Automatic Transmission Operation on page 2-26 for more information. Security Light

The light will go out when the fog lamps are turned off. See Fog Lamps on page 3-19 for more information. Lights On Reminder

For information regarding this light, see Theft-Deterrent System on page 2-18.

See Headlamps on Reminder on page 3-17 for more information.

3-45

Cruise Control Light

Fuel Gage

This light comes on whenever you set your cruise control.

The fuel gage shows approximately how much fuel is in the tank. It works only when the ignition is in ON.

The light will go out when the cruise control is turned off. See Cruise Control on page 3-13 for more information. Highbeam On Light

This light comes on whenever the high-beam headlamps are on.

See Headlamp High/Low-Beam Changer on page 3-10
for more information.

3-46

If the fuel supply gets low, the Fuel Level Low message will appear on the DIC and a single chime will sound. See DIC Warnings and Messages on page 3-61
for more information. Here are a few concerns some owners have had about the fuel gage. All of these situations 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 full. The gage may change when you turn, stop quickly or accelerate quickly. It takes a little more or less fuel to fill the tank than the gage indicated. For example, the gage may have indicated that the tank was half full, but it actually took a little more or less than half the tank’s capacity to fill the tank.

(cid:127) (cid:127) Message Center Message Center (CTS-V) Your vehicle may have a message center that can display information relating to powertrain fluids, tire pressures, vehicle dynamics, speedometer and odometer information, and transmission status. It also displays warning messages. There are two different areas where message center information will be displayed. One display is inside of the tachometer and the other is inside of the speedometer.

These are the controls for the message center. They are located on the left spoke of the steering wheel.

The outboard switch (A and B) controls the display of information inside of the tachometer. The upper button (C) on the inboard switch controls the display of

information inside of the speedometer. The lower button (D) on the inboard switch turns the traction control on or off. See Traction Control System (TCS) (CTS) on page 4-9 or Traction Control System (TCS) (CTS-V) on page 4-10 for more information. Speedometer Display This display will show information relating to vehicle speed, odometer, and transmission status. The information displayed can be changed by pressing (C). Pressing this button cycles the displayed information as follows: digital speedometer only, odometer only, speedometer and odometer, or blank display. When the transmission is shifted into REVERSE (R), an R will appear in the upper right corner. During slow speed maneuvers, the engine’s computer may command the transmission to engage the Skip Shift feature. For more information see Manual Transmission Operation on page 2-30. Tachometer Display Press (B) to cycle through the following displays: coolant temperature, oil pressure, oil temperature, transmission temperature, tire pressure, and lateral acceleration. Press (A) to cycle through the displays in reverse order. If you press (A) for about one second the display will become blank.

3-47

Coolant Temperature

When the coolant temperature is displayed you will see the coolant temperature symbol.

The temperature will be displayed in degrees Fahrenheit or Celsius and there will be a graph at the bottom of the display. If the graph shows the temperature in the shaded area all the way on the right, then the coolant temperature is hot. See Engine Overheating on page 5-30 for more information. Oil Pressure

When the oil pressure is displayed you will see the oil pressure symbol.

The oil pressure will be displayed in psi or kPa and there will be a graph at the bottom of the display. If the graph shows the pressure in the shaded area all the way to the left, then the oil pressure is low. See Engine Oil on page 5-16 and DIC Warnings and Messages on page 3-61 for more information. Oil Temperature

When the oil temperature is displayed you will see the oil temperature symbol.

The temperature will be displayed in degrees Fahrenheit or Celsius and there will be a graph at the bottom of the display. If the graph shows the temperature in the shaded area all the way on the right, then the oil temperature is hot. See Engine Oil on page 5-16
for more information.

3-48

Transmission Temperature

When the transmission temperature is displayed you will see the transmission temperature symbol.

The temperature will be displayed in degrees Fahrenheit or Celsius and there will be a graph at the bottom of the display. If the graph shows the temperature in the shaded area all the way on the right, then the transmission temperature is hot. See DIC Warnings and Messages on page 3-61 and Manual Transmission Fluid on page 5-26 for more information. Tire Pressure When the tire pressure is displayed you will see a vehicle in the display. The numbers in each corner represent the tire pressure for the corresponding tire. The tire pressure will be displayed in psi or kPa. If any of the tires are blinking on the vehicle in the display, this means that the tire pressure in that tire is either high or low. See Tire Pressure Monitor System on page 5-69 for more information.

Lateral Acceleration Lateral acceleration is a measure of how hard you are taking a corner. For example, when you are turning right you will feel your body push to the left. This force is measured in a “g”. This gage will display from 0.00 g to 1.2 g. The lowest reading means there is no lateral acceleration. The highest reading means the force the driver is feeling is 1.2 times the acceleration due to gravity. When (B) is pressed and held while the Lateral Acceleration display is being shown, the peak hold values — both tick marks and numbers — will be reset to zero. Warning Messages The warning messages that are described in the following text are also shown in the tachometer display. While any warning messages are shown, pressing (A) or (B) will acknowledge the warning and then display the gage relating to the error message. For instance, if a tire is below the minimum recommended pressure, the tire pressure warning message will blink on and off (5 times for a low tire warning, continuously for a flat tire warning). The driver can go to the tire pressure display immediately by pressing either button on the outboard switch.

3-49

Transmission Fluid Hot Message

When you see this flashing symbol, the transmission fluid temperature is high (290°F (143°C)).

Hot Coolant Temperature Warning Message

When you see this flashing symbol, the engine coolant temperature is high (257°F (125°C)).

To acknowledge this warning, press either button on the outboard switch on the left spoke of the steering wheel. After you press this button, the warning will redisplay every 10 minutes until the temperature returns to the normal operating range. If this message appears, you may continue to drive at a slower speed while monitoring the transmission fluid temperature. Ideally, the transmission oil temperature should not rise above 265°F (129°C). If you regularly experience temperatures above this limit due to high performance operation, it is recommended to use an auxiliary fluid cooler for the transmission and differential. See your GM dealer for details. If this warning is displayed during normal vehicle operation on flat roads, your vehicle may need service. See your dealer for an inspection. See DIC Warnings and Messages on page 3-61 and Manual Transmission Fluid on page 5-26 for more information.

If this warning is displayed during normal vehicle operation on flat roads, your vehicle may need service. See your GM dealer for an inspection. See Engine Oil on page 5-16 for more information.

3-51

Tire Pressure Warning Message

One-to-Four Shift Message

When you see this flashing symbol, one or more of the vehicle’s tires is either under or over-inflated.

If equipped, this message indicates that you can only shift from FIRST (1) to FOURTH (4) instead of FIRST (1) to SECOND (2).

To acknowledge this warning, press either button on the outboard switch on the left spoke of the steering wheel. There are three levels of warning for this display:

1. High Tire Pressure (above 42 psi (290 kPa)) 2. Low Tire Pressure (below 25 psi (170 kPa)) 3. Flat Tire (below 5 psi (35 kPa)) For conditions 1 and 2, this warning will flash five times and the display will then show the tire pressure gage. For condition 3, this warning will flash continuously until the driver acknowledges it. In any of the three cases, the warning will redisplay every 10 minutes until the situation is corrected. Conditions 2 and 3 will also display a warning light elsewhere on the cluster that will stay illuminated after this warning is acknowledged. See Tire Pressure Light on page 3-41 for more information. Also see Tire Pressure Monitor System on page 5-69 for more information on tire pressure specifications.

3-52

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 message will come on when:

The engine coolant temperature is higher than 169°F (76°C), you are going 15 to 19 mph (24 to 31 km/h) and you are 21 percent throttle or less.

Each one must be reset individually. For a detailed description of the menu items and how to reset them, see “Vehicle Information Menu Item Descriptions” later in this section. You can view any of these items at any time, but only one item can be displayed at a time. Vehicle Information Menu Item Descriptions The following paragraphs contain a more detailed description of each menu item:

OUTSIDE TEMP: If you select this item, the current outside temperature is displayed at the top of the screen. It will be in either degrees Fahrenheit (°F) or degrees Celsius (°C) depending upon whether the system is set for English or metric units. If you wish to change the units, see DIC Main Menu on page 3-57.

(cid:127) (cid:127) MI TRIP A and B (KM TRIP A and B): For information on the trip odometers, see Trip Odometers on page 3-33.

MILES RANGE (KM RANGE): If you select this item, the approximate number of remaining miles or kilometers you can drive without refueling is displayed. This estimate is based on the current driving conditions and will change if the driving conditions change. For example, if you are driving in traffic making frequent stops, the display may read one number, but if you enter the freeway, the number may change even though you still have the same amount of gas in the gas tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving.

If your vehicle is low on fuel, the Fuel Level Low message will be displayed. See “Fuel Level Low” under DIC Warnings and Messages on page 3-61 for more information.

MPG AVG (L/100 KM AVG): If you select this item, the approximate average miles per gallon (mpg) or liters per 100 kilometers (L/100 km) is displayed. This number is calculated based on the number of mpg (L/100 km) recorded since the last time this menu item was reset.

To reset the MPG AVG (L/100 KM AVG), press the CLR button located to the right of the screen. The display will return to zero.

MPG INST (L/100 KM INST): If you select this item, the current fuel economy is displayed. This number reflects only the fuel economy that the vehicle has right now and will change frequently as driving conditions change. Unlike average fuel economy, this menu item cannot be reset.

GAL FUEL USED (L FUEL USED): If you select this item, the number of gallons or liters of fuel used since the last reset of this menu item is displayed. To reset GAL FUEL USED (L FUEL USED), press the CLR button located to the right of the screen. The display will return to zero.

AVG MPH (AVG KM/H): If you select this item, the average speed of the vehicle is displayed in miles per hour (mph) or kilometers per hour (km/h). This average is calculated based on the various vehicle speeds recorded since the last reset of this menu item. To reset AVG MPH (AVG KM/H), press the CLR button located to the right of the screen. The display will return to zero.

TIMER: If you select this item, a timing feature is displayed. The timer functions like a stopwatch in that you can record the time it takes to travel from one point to another. To turn on the timer, press the CLR button located to the right of the screen once. The display will read 00:00:00 TIMER ON and begin counting.

3-55

To turn off the timer, press the CLR button again. When the timer is off, the display will show the timer value and TIMER OFF. The timing feature will stop.

To reset the timer, turn off the timer and then press and hold the CLR button. The display will return to zero.

BATTERY VOLTS: If you select this item, the current battery voltage is displayed. If the voltage is in the normal range, the display will have OK after it. For example, the display may read 13.2 BATTERY VOLTS OK.

If there is a problem with the battery charging system, there are four possible DIC messages that may be displayed. See DIC Warnings and Messages on page 3-61 for more information.

ENGINE OIL LIFE: If you select this item, the percentage of remaining oil life is displayed. If you see 99% ENGINE OIL LIFE on the display, that means that 99% of the current oil life remains.

When the oil life is depleted, the Change Engine Oil message will appear on the display. See your GM dealer for service. In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Scheduled Maintenance on page 6-4 and Engine Oil on page 5-16 for more information.

When you reset the Change Engine Oil message by clearing it from the display, you still must reset the engine oil life system separately. For more information on resetting the engine oil life system, see “How to Reset the Engine Oil Life System and the Oil Life Indicator” under Engine Oil Life System on page 5-22. If you clear the Change Engine Oil message from the display, it will not re-appear.

TRANS FLUID LIFE (Automatic Transmission): If you select this item, the percentage of remaining transmission fluid life is displayed. If you see 99% TRANS FLUID LIFE on the display, that means that 99% of the current transmission fluid life remains.

When the transmission fluid life is depleted, the Change Trans Fluid message will appear on the display. You should change the transmission fluid as soon as possible.
