conditioning compressor on and off. % (Air Conditioning Off): When you turn the air conditioning off, this symbol will appear on the display. When air conditioning is selected or in AUTO mode, the system will run the air conditioning automatically to cool and dehumidify the air entering the vehicle. If you select A/C off while in front defrost or defog, the A/C off symbol will flash to let you know this is not allowed. This is to prevent fogging. On hot days, open the windows long enough to let hot inside air 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. On cool, but sunny days while using manual operation of the automatic system, use bi-level to deliver warm air to the floor and cooler air to the instrument panel outlets. To warm or cool the air delivered, turn the temperature knob to the desired setting. In AUTO mode the system will cool and dehumidify the air inside the vehicle. Also while in AUTO mode, the system will maximize its performance by using recirculation as necessary.

Operation Tips


Keep the hood and front air inlets free of ice, snow, or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows. Keep the air path under the front seats clear of objects. This helps air to circulate throughout your vehicle. Adding outside equipment to the front of your vehicle, such as hood-air deflectors, etc., may affect the performance of the heating and air conditioning system. Check with your dealer before adding equipment to the outside of your vehicle.


Climate Controls Personalization If your vehicle is equipped with the electronic climate control system, you can store and recall the climate control settings for temperature, air delivery mode and fan speed for two different drivers. The personal choice settings recalled are determined by the transmitter used to enter the vehicle. After the button with the unlock symbol on a remote keyless entry transmitter is pressed, the climate control will adjust to the last settings of the identified driver. The settings can also be changed by pressing one of the memory buttons (1 or 2) located on the driver’s door. When adjustments are made, the new settings are automatically saved for that driver.

Warning Lights, Gages and Indicators This part describes the warning lights and gages 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. 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 also has a message center that works along with the warning lights and gages. See Driver Information Center (DIC) on page 3-46.

Instrument Panel Cluster


United States 2500 series shown, 1500 series, Canada and North Face edition similar


3-31


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 vehicle’s odometer works together with the driver information center. You can set a personal trip and business trip odometer. See “Trip Information” under DIC Operation and Displays on page 3-46. The odometer mileage can be checked without the vehicle running. Simply press the trip stem on the instrument panel cluster. If your vehicle ever needs a new odometer installed, the new one will be set to the correct mileage total of the old odometer. Tachometer Your tachometer displays the engine speed in revolutions per minute (rpm). Notice: Do not operate the engine with the tachometer in the shaded warning area, or engine damage may occur. 3-32


Safety Belt Reminder Light


When the key is turned to RUN 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, 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 and the crash sensing and diagnostic module. For more information on the air bag system, see Air Bag Systems on page 1-52.


This light will come on when you start your seconds when vehicle, and it will flash for a few seconds. the light should go out. This means the system is ready.

Passenger Air Bag Status Indicator


If your vehicle has the passenger sensing system your rearview mirror will have a passenger air bag status indicator.


Passenger Air Bag Status Indicator - United States


Passenger Air Bag


Status Indicator


- Canada


3-33


When the ignition key is turned to RUN or START, the passenger air bag 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 air bag. If the word ON or the on symbol is lit on the passenger air bag status indicator, it means that the right front passenger’s frontal air bag is enabled (may inflate).


If the word OFF or the off symbol is lit on the air bag status indicator, it means that the passenger sensing system has turned off the right front passenger’s frontal air bag. See Passenger Sensing System on page 1-61 for more on this, including important safety information. 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.


It 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 air bag. A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Don’t use a rear-facing child restraint in the right front passenger’s seat unless the air bag has been turned off.


3-34


If the off indicator and the air bag readiness light ever come on together, it means that something may be wrong with the air bag 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 air bag. See “Air Bag Readiness Light” in the Index.


Charging System Light


Voltmeter Gage


The charging system light will come on briefly when you turn on the ignition, but the engine is not running, as a check to show you it is working.


When your engine is not running, but the ignition is in RUN, this gage shows your battery’s state of charge in DC volts.


It should go out once the engine is running. If it stays on, or comes on while you are driving, you may have a problem with the charging system. It could indicate that you have problems with a generator drive belt, or another electrical problem. Have it checked right away. Driving while this light is on could drain your battery. When this light comes on the DIC will also display the battery not charging message. See DIC Warnings and Messages on page 3-56. If you must drive a short distance with the light on, be certain to turn off all your accessories, such as the radio and air conditioner.


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. 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.


3-35


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. 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 and a chime sounds there could be a brake problem. Have your brake system inspected right away.

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 4-48.


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.


Your brake system may not be w _ ting 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.


That’s normal. 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 the light stays on, or comes on when you’re driving, your vehicle needs service. You will also hear a chime sound when the light is on steady. 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. In addition to both lights, you will also hear a chime sound on the first occurrence of a problem and each time the car is shut off and then restarted. See Brake System Warning Light on page 3-36.


3-37


Traction Off Light


If you have the Traction Assist System or the Stabilitrak@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:


If you turn the system off by pressing the TAS on/off button located to the left of the steering wheel, the light will come on and stay on. To turn the system back on, press the button again; the light should go off.


3-38


If you move the shift lever to FIRST (l), 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 (TAS) on page 4-9. 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 (TAS) on page 4-9. 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. 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.


For more information on the traction off light and Stabilitrak@, see Sfabi/itrak@ System on page 4-1 1.


Engine Coolant Temperature Gage


Transmission Temperature Gage


United States


Canada


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 (1 25°C) mark, it indicates that the cooling system is working beyond its capacity. See Engine Overheating on page 5-27.


Your vehicle is 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 (1 30°C). At approximately 265°F (1 30"C), the DIC will display a TRANSMISSION 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 (1 27°C).


3-39


See Driver lnformation Center (DIC) on page 3-46 for further information. If the transmission fluid reaches temperatures of approximately 275°F (1 35°C) or greater, the DIC will display a TRANS HOT IDLE ENGINE warning message and a chime will sound. 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. 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:


Towing a trailer,


0 hot outside air temperatures, 0 hauling a large or heavy load,


low transmission fluid level, high transmission fluid level, restricted air flow to the radiator.


3-40


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 on page 6-5 for the proper transmission maintenance intervals. 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 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. Phis could [lead to costly repairs that may not be covered by your warranty.


Nofice: 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. 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: 0 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.


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. If the Light is Flashing The following may prevent more serious damage to your vehicle: 0 Reducing vehicle speed.


Avoiding hard accelerations. 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 drive the vehicle to your dealer or qualified service center for service.


3-4 1


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 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.


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 on page 5-7. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. Did you just drive through a deep puddle of water? If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off. 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.


3-42


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.


Oil Pressure Gage


The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals). Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range. A reading in the low pressure zone may be caused by a dangerously low oil level or some other problem causing low oil pressure. Check your oil as soon as possible. See Engine Oil on page 5-15.


if the oil pressure is low. If Don’t keep drivimmy 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: Damage to your engine from neglected oil problems can be costly and is not covered by your warranty.

Here are some situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage.


United States


~~ Canada


When the ignition is on, the fuel gage tells you about how much fuel you have left in your tank. The gage will first indicate empty before you are out of fuel, and you should get more fuel as soon as possible.


At the gas station, the fuel pump shuts off before the gage reads full. It takes a little more or less fuel to fill up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank. The gage goes back to empty when you turn off the ignition.


Low Fuel Warning Light The light next to the fuel gage will come on briefly when you are starting the engine. This light comes on when the fuel tank is low on fuel. To turn it off, add fuel to the fuel tank. See fuel on page 5-5.
