Instrument Panel Cluster

United States Heavy Duty Automatic Transmission version shown. Canada, Light Duty Automatic and

Manual Transmission Clusters similar.

2-96

Your instrument cluster is designed to let you know at a glance how your vehicle is running. You’ll know how fast you’re going, about how much fuel you have and many other things you’ll need to know to drive safely and economically. Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada).

Trip Odometer The trip odometer can tell you how far your vehicle has been driven since you last set the trip odometer to zero. Press the reset button to toggle between the trip odometer and the regular odometer. Holding the reset button for two seconds while the trip odometer is displayed will reset it.

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’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.

2-98

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’re a big help. Your vehicle may also have a driver information system that works along with the warning lights and gages. See “Message Center” in the Index. Safety Belt Reminder Light When the key is turned to RUN or START, a chime will come on for about six 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 about 20 seconds, then it will flash for about 55 seconds.

If the driver’s belt is already buckled, neither the chime nor the light will come on.

Air Bag Readiness Light There is an air bag readiness light on the instrument panel, which shows the air bag symbol. The system checks the air bag’s electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the air bag sensors, the air bag modules, the wiring, the passenger air bag suppression circuit and the crash sensing and diagnostic module. For more information on the air bag system, see “Air Bag” in the Index.

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 air bag readiness light stays on after you start the vehicle or comes on when you are driving, your air bag system may not work properly. Have your vehicle serviced right away.

CAUTION:

If the air bag readiness light stays on after you start your vehicle, it means the air bag system may not be working properly. The air bags 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 air bag readiness light stays on after you start your vehicle.

The air bag readiness light should flash for a few seconds when you turn the ignition key to RUN. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem.

2-99

Air Bag Off Light When you turn the right front passenger’s air bag off, this light will come on and stay on to remind you that the air bag has been turned off. This light will go off when you turn the air bag back on again. See “Air Bag Off Switch” in the Index for more on this, including important safety information.

CAUTION:

If the right front passenger’s air bag is turned off for a person who isn’t in a risk group identified by the national government, that person won’t have the extra protection of an air bag. In a crash, the air bag wouldn’t be able to inflate and help protect the person sitting there. Don’t turn off the passenger’s air bag unless the person sitting there is in a risk group. See “Air Bag Off Switch” in the Index for more on this, including important safety information.

2-100

CAUTION:

If the air bag readiness light ever comes on when you have turned off the air bag, it means that something may be wrong with the air bag system. The right front passenger’s air bag could inflate even though the switch is off. If your vehicle is a regular cab pickup and this ever happens, don’t let anyone whom the national government has identified as a member of a passenger air bag risk group sit in the right front passenger’s position (for example, don’t secure a rear-facing child restraint in your vehicle) until you have your vehicle serviced. If your vehicle is an extended cab pickup and this ever happens, don’t let anyone whom the national government has identified as a member of a passenger air bag risk group sit in the right front passenger’s position (for example, don’t secure a rear-facing child restraint in the right front passenger’s seat) until you have your vehicle serviced.

Voltmeter

United States

Canada

When your engine is not running, but the ignition is in RUN, this gage shows your battery’s state of charge in DC volts. When the engine is running, the gage shows the condition of the charging system. Readings between the low and high warning zones indicate the normal operating range.

2-101

Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. You can only drive for a short time with the reading in either warning zone. If you must drive, turn off all unnecessary accessories. Readings in either warning zone indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible.

Shift Light (If Equipped)

This light is used on some models with manual transmissions.

The SHIFT indicator light will help you get the best fuel economy. See “Shift Light” or “Shift Speeds” in the index for more information.

2-102

Brake System Warning Light With the ignition on, the brake system warning light will flash when you set the parking brake. The light will flash if the parking brake doesn’t release fully. If you try to drive with the parking brake engaged, a chime will sound when the vehicle speed is greater than 3 mph (5 km/h). 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 could be 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 RUN. If it doesn’t come on then, have it fixed so it will be ready to warn you if there’s a 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” in the Index.

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’ve pulled off the road and stopped carefully, have the vehicle towed for service.

2-103

Anti-Lock Brake System Warning Light With the anti-lock brake system, this light will come on when you start your engine and may stay on for several seconds. That’s normal.

If the light stays on, or comes on when you’re driving, your vehicle needs service. If the regular brake system warning light isn’t on, you still have brakes, but you don’t have anti-lock brakes. If the regular brake system warning light is also on, you don’t have anti-lock brakes and there’s a problem with your regular brakes. See “Brake System Warning Light” earlier in this section. The anti-lock brake system warning light should come on briefly when you turn the ignition key to RUN. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem.

Low Traction Light (If Equipped)

If you have the Traction Assist System, this light will come on when the system is limiting wheel spin. See “Traction Assist System” in the Index.

You may feel or hear the system working or notice a lack of accelerator response, but this is normal. The LOW TRACTION light also comes on briefly when you turn your ignition to RUN. If the light doesn’t come on then, the system may require service; have it fixed so it will be there to tell you when the traction system is active. Slippery road conditions may exist if this light comes on, so adjust your driving accordingly.

2-104

Traction Off Light (If Equipped)

If you have the Traction Assist System, this light should come on briefly when you turn the ignition to RUN.

If the light doesn’t come on then, the system may require service; have it fixed so it will be there to warn you if the system is turned off. If the light stays on, or comes on when you’re driving, there may be a problem with your Traction Assist System and your vehicle may need service. When this light is on, the system will not limit wheel spin. Adjust your driving accordingly. The TRACTION OFF light may come on for the following reasons: D If you turn the system off by pressing the TAS on/off button the light will come on and stay on. To turn the system back on, press the button again; the light should go off.

D If you move the shift lever to FIRST (1), the light

will come on and stay on to indicate that the traction system is off. This is normal operation. To turn the system back on, move the shift lever back to a position other than FIRST (1); the light should go off. See “Traction Assist System” in the Index. D The light will come on and stay on if the TAS

automatic engagement feature has been turned off. To turn the system on, press the TAS off/on button; the light should go off. To turn the automatic engagement feature back on, see “Traction Assist System” in the Index.

D If the Traction Assist System is affected by an anti-lock brake system, TAS or engine-related problem, the system will turn off and the light will come on. Have your vehicle serviced.

D If the vehicle is driven over an extremely rough road,

the system will turn off and the light will come on. The light will go off a few seconds after the rough road conditions go away or when the vehicle comes to a complete stop. This is normal operation.

2-105

Engine Coolant Temperature Gage

Transmission Temperature Gage (If Equipped)

United States

Canada

This gage shows the engine coolant temperature. It also provides an indicator of how hard your vehicle is working. During a majority of the operation, the gage will read 210_F (100_C) or less. If you are pulling a load or going up hills, it is normal for the temperature to fluctuate and approach the 250_F (122_C) mark. If the gage reaches the 260_F (125_C) mark, it indicates that the cooling system is working beyond its capacity. See “Engine Overheating” in the Index.

2-106

United States

Canada

Your vehicle may be equipped with a transmission temperature gage. When your ignition is on, the gage shows the temperature of the transmission fluid. The normal operating range is from 100_F (38_C) to about 265_F (130_C).

At approximately 265_F (130_C), the message center will display a TRANS FLUID HOT message and the transmission will enter a transmission protection mode. When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. The transmission will return to normal shifting patterns when the transmission fluid temperature falls below 260_F (127_C). See “Message Center” in the Index for further information. If the transmission fluid reaches temperatures of approximately 275_F (135_C) or greater, the message center will display a TRANS HOT...IDLE ENG warning message. Pull the vehicle off the roadway when it is safe to do so. Set the parking brake, place the transmission in PARK (P) and allow the engine to idle until the transmission temperature falls below 260_F (127_C). If the transmission continues to operate above 265_F (130_C), please contact your nearest dealer or the GM Roadside Assistance Center. See “Roadside Assistance” in the Index.

NOTICE:

If you keep driving your vehicle with the transmission temperature gage above the normal operating range, you can damage the transmission. This could lead to costly repairs that may not be covered under your warranty.

The following situations can cause the transmission to operate at higher temperatures: D Towing a trailer D Hot outside air temperatures D Hauling a large or heavy load D Low transmission fluid level D High transmission fluid level D Restricted air flow to the radiator and the auxiliary

transmission oil cooler (if equipped).

A temporary solution to hotter transmission operating temperatures may be to let the transmission cool down. If the transmission is operated at higher temperatures on a frequent basis, see “Scheduled Maintenance” in the Index for the proper transmission maintenance intervals.

2-107

Malfunction Indicator Lamp (Service Engine Soon Light in the United States or Check Engine Light in Canada)

United States

Canada

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 SERVICE ENGINE SOON or 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 a while, 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.

2-108

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 the SERVICE ENGINE SOON or CHECK ENGINE 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.

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 doesn’t come on, have it repaired. This light will also come on during a malfunction in one of two ways: D Light Flashing -- A misfire condition has been

detected. A misfire increases vehicle emissions and may damage the emission control system on your vehicle. Dealer or qualified service center diagnosis and service may be required.

D Light On Steady -- An emission control system malfunction has been detected on your vehicle. Dealer or qualified service center diagnosis and service may be required.

2-109

If the Light Is Flashing The following may prevent more serious damage to your vehicle: D Reducing vehicle speed. D Avoiding hard accelerations. D Avoiding steep uphill grades. D 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 drive the vehicle to your dealer or qualified service center for service.

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 Your Tank” in the Index. 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.

2-110

Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See “Fuel” in the Index. 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, have your dealer or qualified service center 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 in order to help your vehicle pass an inspection: Your vehicle will not pass this inspection if the SERVICE ENGINE SOON or CHECK ENGINE light is on or not working properly. Your vehicle will not pass this inspection if the OBD (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if you have recently replaced your battery or if your battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This may take several days of routine driving. If you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, see your dealer or qualified service center to prepare the vehicle for inspection.

Move the knob clockwise toward 82_F (28_C) for warmer air. Move the knob counterclockwise toward 66_F (19_C) for cooler air. When the system is set for automatic operation, sensors will control the fan speed. Full Hot: If you turn the temperature knob past 82_F (28_C), the system will go into the “full hot” mode. The system will remain at that maximum heating setting and the fan will blow at the speed the fan knob is set to. If the fan is in AUTO, it will run at full speed.

Full Cold: If you turn the temperature knob past 66_F (19_C), the system will go into the “full cold” mode. The system will remain at that maximum cooling setting and the fan will blow at the speed the fan knob is set to. If the fan is in AUTO, it will run at full speed. Mode Knob -- Manual Operation The right knob on the control panel allows you to choose the direction of air delivery. You can choose to set the climate control system yourself, or let the system work for you by placing the system in AUTO mode. See “Mode Knob -- Automatic Operation” later in this section.

Press this button again to turn off the recirculation feature. Recirculation may be selected with the fan control in OFF to limit odors, outside air and dust from entering your vehicle. Pressing the recirculation button will cancel the outside air button.

A/C: Press this button to turn the air conditioning on and off. The system will cool and dehumidify the air inside the vehicle when the A/C light is on. When in AUTO, the A/C is automatically engaged when necessary. Air conditioning will be automatically disabled when the outside air temperature drops below a level at which air conditioning is effective. Remember that in order for the automatic system to perform well, it needs A/C to provide cooling performance.

3-7

Mode Knob -- Automatic Operation The right knob on the control panel allows you to choose the direction of air delivery. When the system is set for automatic operation, sensors will control the air delivery mode. Air will come primarily from the floor or instrument panel outlets, with some air directed to the windshield to prevent fogging. When the system is in AUTO mode, the air conditioning light will turn on, and the recirculation and outside air lights turn off. With the system in full auto control (both the fan and mode knobs in AUTO), you still have the ability to override any function. However, continually overriding the outside air or the A/C compressor will limit the ability of the system to cool the vehicle quickly. If you push a button for a function which is not available, the light next to that button will flash three times to alert you that it’s not available. To find your comfort zone, start with the 74_F (23_C) setting and allow about 20 minutes for the system to adjust the temperature if necessary.

With the automatic setting, the air conditioning compressor automatically cycles when needed to cool the air. In cold weather, when the system senses the need for heat, the airflow will be directed out of the floor outlets. As the interior temperature approaches a desired setting, the fan speed will decrease. To maintain interior comfort, the airflow will adjust between the instrument panel outlets and floor outlets. On bright sunny days in cool weather, the airflow may come out of the air conditioning and floor outlets (bi-level mode) to maintain comfort and prevent stuffiness. To avoid blowing cold air in cold weather, the system will delay turning on the fan until warm air is available. The length of delay depends on the outside air temperature, engine coolant temperature or the time since the engine was last started. As the coolant warms up, the fan speed will gradually increase and air will flow from the floor outlets, with some airflow to the windshield to prevent fogging under most normal conditions. Be careful not to put anything over the solar sensor located around the center of the instrument panel. This sensor is used by the automatic system to regulate temperature.

3-8

Air Conditioning On hot days, open the windows long enough to let hot air inside escape. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work its best. The recirculation button allows the air inside your vehicle to be recirculated. This setting helps to maximize your air conditioner’s performance and your vehicle’s fuel economy. This setting also cools air the fastest and can be used to keep unwanted odors and/or dust from entering the vehicle. When using the air conditioner, turn off the recirculation button after the vehicle reaches a comfortable interior temperature. When the right knob on the control panel is between floor and defrost, the recirculation feature will not function to reduce window fogging. The A/C button, below the mode knob, allows the air coming into your vehicle to be cooled. This setting is useful for normal cooling on hot days.

When you use A/C with the recirculation button pushed in, turn off recirculation as soon as the vehicle reaches a comfortable interior temperature. Maximum air conditioning performance is obtained by pressing the A/C button, the recirculation button and turning the temperature knob fully counterclockwise to the blue area. This setting also cools air the fastest. After the vehicle’s interior reaches a comfortable temperature, press the outside air button to place the air conditioning system in the normal mode.

Passenger Compartment Air Filter (If Equipped) If your vehicle has air conditioning, it is equipped with a passenger compartment air filter, which filters outside air entering the vehicle. For information on replacing the filter see “Passenger Compartment Air Filter” in the Index.

3-9

Heating The heater works best if you keep your windows closed while using it. On cold days, use the floor or bi-level setting with the temperature knob in the red area. On cold days, approximately 32_F (-0_C) or lower, if your vehicle is equipped with an automatic transmission, you may experience differences in how the transmission shifts until the engine is warm. This feature automatically reduces the time it takes for the engine to reach normal operating temperature and shortens the time it takes the heater to reach full output. If you use the engine coolant heater before starting your engine in cold weather, 20_F (-8_C) or lower, the heating system will produce warmer air faster to heat the passenger compartment. The use of an engine coolant heater also reduces the time it takes for the engine to reach normal operating temperature. For more information, see “Engine Coolant Heater” in the Index.

Defogging and Defrosting On cool, humid days, use defrost to keep the windshield and side windows clear. Use defrost to remove fog or ice from the windshield in extremely humid or cold conditions. Use defrost with the temperature knob toward the red area and the fan control turned all the way to the right. Rear Window Defogger (If Equipped) If you see lines running across the rear window, your vehicle has a rear window defogger. The lines warm the glass.

To turn on the rear window defogger, press this button next to the fan knob. The rear window defogger will only work if the ignition is in RUN. For best results, clear the window of as much snow or ice as possible.

3-10

The defogger will shut itself off after several minutes. If you need additional warming time, press the button again. You can turn the defogger off at any time by pressing the button. If your vehicle is equipped with heated outside mirrors, the rear window defogger button will also activate the heated outside mirrors. Do not attach a temporary vehicle license, tape or decals across the defogger grid on the rear window.

NOTICE:

Don’t use a razor blade or something else 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.

Ventilation System For mild outside temperatures when little heating or cooling is needed, use vent to direct outside air through your vehicle. Your vehicle’s ventilation system supplies outside air to the inside of your vehicle when it is moving. With the side windows closed, air will flow into the front air inlet grilles, through the vehicle, and out the air exhaust valves. Outside air will also enter the vehicle when the floor or the air conditioning fan is running, unless you have the recirculation button pushed in. For more information on the recirculation mode, see “Air Conditioning” earlier in this section.

3-11

Ventilation Tips D Keep the hood and front air inlet free of ice, snow or

any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows.

D When you enter a vehicle in cold weather, turn the fan knob all the way to the right for a few moments before driving. This helps clear the intake ducts of snow and moisture, and reduces the chance of fogging the inside of your windows.

D Keep the air path under the front seats clear of objects. This helps air to circulate throughout your vehicle.

D The use of hood air deflectors may adversely affect the performance of the heating and air conditioning system.

Your vehicle has air outlets in the center and on the sides of your instrument panel.

You can move the levers from side-to-side or up and down to direct the flow of air. The left driver and passenger outlets on vehicles equipped with air conditioning have shut off levers. Turn the knob counterclockwise to shut off air flow or clockwise to allow air flow. When you close an outlet, it will increase the flow of air coming out of any outlets that are open. The center outlet does not completely shut off airflow.

Theft-Deterrent Feature (If Equipped) THEFTLOCKR is designed to discourage theft of your radio. It works by using a secret code to disable all radio functions whenever battery power is removed. The THEFTLOCK feature for the radio may be used or ignored. If ignored, the system plays normally and the radio is not protected by the feature. If THEFTLOCK is activated, your radio will not operate if stolen. When THEFTLOCK is activated, the radio will display LOC to indicate a locked condition anytime battery power has been interrupted. If your battery loses power for any reason, you must unlock the radio with the secret code before it will operate.
