2003 Chevrolet Suburban Owners Manual

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:

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:

Reducing vehicle speed. Avoiding hard accelerations.

0 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.

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 5-9. 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.

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. 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.

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 oft, 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.

Oil Pressure Gage

t kc

J if the oil pressure is

Dc 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.

United States

Canada

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 Oil Pressure Low under DIC Warnings and Messages on page 3-62 and Engine Oil on page 5- 17.

Notice: Damage to your engine from neglected oil problems can be costly and is not covered by your warranty. Cruise Control Light

The cruise light comes on whenever you set your cruise control. See “Cruise Control’’ under Turn Signal/Multifunction Lever on page 3-7.

Fuel Gage

United States

Canada

The fuel gage, when the ignition is on, tells you about how much fuel you have left in your tank. The gage will first indicate empty before you are out or fuel, and you should get more fuel as soon as possible. When the fuel tank is low the FUEL LEVEL LOW message will appear. See Driver Information Center (DIC) on page 3-52.

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

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.

SERVICE STABILITY If you ever see the SERVICE STABILITY message, it means there may be a problem with your Stabilitrak@ system. If you see this message try to reset the system (stop; turn off the engine; then start the engine again). If the SERVICE STABILITY message still comes on, it means there is a problem. You should see your dealer for sewice. The vehicle is safe to drive, however, you do not have the benefit of Stabilitrak@ , so reduce your speed and drive accordingly. STABILITY SYS ACTIVE You may see the STABILITY SYS ACTIVE message on the DIC. It means that an advanced computer-controlled system has come on to help your vehicle continue to go in the direction in which you’re steering. Stabilitrak@ activates when the computer senses that your vehicle is just starting to spin, as it might if you hit a patch of ice or other slippery spot on the road. When the system activates, you may hear a noise or feel a vibration in the brake pedal. This is normal. When the STABILITY SYS ACTIVE message is on, you should continue to steer in the direction you want to go. The system is designed to help you in bad weather or other difficult driving situations by making the most of whatever road conditions will permit.

STABILITY SYS DISABLED The STABILITY SYS DISABLED message will turn on when you press the Stabilitrak@ button, or when the stability control has been automatically disabled. To limit wheel spin and realize the full benefits of the stability enhancement system, you should normally leave Stabilitrak@ on. However, you should turn Stabilitrak@ off if your vehicle gets stuck in sand, mud, ice or snow and you want to “rock your vehicle to attempt to free it, or if you are driving in extreme off-road conditions and require more wheel spin. See If You Are Stuck: In Sand, Mud, Ice or Snow on page 4-50. To turn the Stabilitrak@ system back on press the Stabilitrak@ button again. There are four conditions that can cause this message to appear. One condition is overheating, which could occur if Stabilitrak@ activates continuously for an extended period of time. The message will also be displayed if the brake system warning light is on. See Brake System Warning Light on page 3-47. The message could be displayed if the stability system takes longer than usual to complete its diagnostic checks due to driving conditions. Also, if an engine or vehicle related problem has been detected, and the vehicle needs service, the message will appear. The message will turn off as soon as the conditions that caused the message to be displayed are no longer present.
