Flash-To-Pass Feature This feature allows you to use your high-beam headlamps to signal a driver in front of you that you want to pass. It works even if your headlamps are off To use it, pull the turn signal lever toward you. If your headlamps are off or on low-beam, your high-beam headlamps will turn on. They’ll stay on as long as you hold the lever toward you and the high-beam indicator on the instrument panel will come on. Release the lever to turn the high-beam headlamps off. Windshield Wipers 0 : OFF Q : MIST You control the windshield wipers by turning the band with the wiper symbol on it. For a single wiping cycle, turn the band to mist. Hold it there until the wipers start, then let go. The wipers will stop after one wipe. If you want more wipes, hold the band on mist longer. You can set the wiper speed for a long or short delay between wipes. This can be very useful in light rain or snow. Turn the band to choose the delay time. The closer to the top of the lever, the shorter the delay.

For steady wiping at low speed, turn the band away from you to the first solid band past the delay settings. position. For high-speed wiping, turn the band further, to the second solid band past the delay settings. To stop the wipers, move the band to off position. Be sure to clear ice and snow from the wiper blades before using them. If they’re frozen to the windshield, carefully loosen or thaw them. If your blades do become worn or damaged, get new blades or blade inserts. Windshield Washer There is a paddle marked with the windshield washer symbol at the top of the multifunction lever. To spray washer fluid on the windshield, push the paddle. The wipers will clear the window and then either stop or return to your preset speed.

Cruise Control

This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). If you apply your brakes, or press the clutch pedal (if equipped), the cruise control will disengage.

Cruise control can be dangerous where you can’t drive safely at a steady speed. So, don’t 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. Don’t use cruise control on slippery roads.

0 : off I : On t : Resume/Accelerate

With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator.

3-1 0

Setting Cruise Control

If you leave your cruise control on when you’re not using cruise, you might hit a button and go into cruise when you don’t 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.

The cruise light on the instrument panel will illuminate when the cruise control is engaged. Resuming a §et Speed Suppose you set your cruise control at a desired speed and then you apply the brake or press the clutch pedal (if equipped). 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 from on to resume/accelerate briefly. you’ll go right back up to your chosen speed and stay there. If you hold the switch at resume/accelerate briefly, the vehicle will keep going faster until you release the switch or apply the brake. So unless you want to go faster, don’t hold the switch at resume/accelerate.

3-1 1

Increasing Speed While Using Cruise Control There are two ways to go to a higher speed:

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. 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 to resume/accelerate briefly. Each time you do this, your vehicle will go about 1 mph (1.6 km/h) faster.

Reducing Speed While Using Cruise Control

Press and hold the set 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, press the set button briefly. Each time you do this, you’ll go about 1 mph (1.6 km/h) slower.

3-1 2

Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase your speed. When you take your foot off the pedal, your vehicle will slow down to the cruise control speed you set earlier. Using Cruise Control on Hills How well your cruise control will work on hills depends upon your speed, load and the steepness of the hills. When going up steep hills, you may want to step on the accelerator pedal to maintain your speed. When going downhill, you may have to brake or shift to a lower gear to keep your speed down. Of course, applying the brake takes you out of cruise control. Many drivers find this to be too much trouble and don’t use cruise control on steep hills. Ending Cruise Control There are two ways to turn off the cruise control:

Step lightly on the brake pedal. Step lightly on the clutch pedal (if equipped). Move the cruise control switch to off

Erasing Speed Memory When you turn off the cruise control or the ignition, your cruise control set speed memory is erased.

Exterior Lamps

I he switch on the driver’s side of your instrument panel operates the exterior lamps. Turn the control clockwise to operate the lamps. The exterior lamp switch has four positions:

0 (OFF): Turning the switch to this position turns off

the Daytime Running Lamps (DRL) and the automatic headlamps. An indicator light will illuminate when the position is selected.

(Parking Lamps): Turning the control to this

too: position turns on the parking lamps, together with the following: 0 Sidemarker Lamps * Taillamps

License Plate Lamps Instrument Panel Lights

0 Roof Marker Lamps (If Equipped)

a (Headlamps): Turning the switch to this position

turns on the headlamps, together with the previously listed lamps and lights. You can switch your headlamps from high to low-beam by pushing the turn signal/high-beam lever towards the instrument panel. A circuit breaker protects your headlamps. If you have an electrical overload, your headlamps will flicker on and off. Have your headlamp wiring checked right away if this happens.

Automatic Headlamp System When it is dark enough outside, your automatic headlamp system will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps and the instrument panel lights. The radio lights will also be dim. Your vehicle is equipped with a light sensor located on the top of the instrument panel in the defroster grille. Be sure it is not covered, or the system will be on whenever the ignition is on. The system may also turn on your headlamps when driving through a parking garage, heavy overcast weather or a tunnel. This is normal. There is a delay in the transition between the daytime and nighttime operation of the Daytime Running Lamps (DRL) and the automatic headlamp systems so that driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp system will only be affected when the light sensor sees a change in lighting lasting longer than the delay. If you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave the garage, it will take approximately one minute for the automatic headlamp system to change to DRL if it is bright enough outside. During that delay, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel 3-1 4

brightness control is in the full bright position. See “Instrument Panel Brightness Control’’ under Interior Lamps on page 3- 17. To idle your vehicle with the automatic headlamp system off, turn the control to the off position. You may be able to turn off your automatic headlamp system. See Daytime Running Lamps (DRL) later in this section for more information. You may be able to turn off your Automatic Headlamp System. See “Daytime Running Lamps (DRL)” later in this section for more information. As with any vehicle, you should turn on the regular headlamp system when you need them. Lamps On Reminder A reminder chime will sound when your headlamps or parking lamps are manually turned on and your ignition is off, in LOCK, ACCESSORY, or your door is open. To disable the chime, turn the light off then back on. Daytime Running Lamps 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 come on when the following conditions are met:

the ignition is on, the exterior lamps control is in AUTOj the automatic transmission is not in PARK (P), and the light sensor determines it is daytime.

When the DRL are on, only your DRL lamps will be on. The taillamps, sidemarker and other lamps won’t be on. The instrument panel won’t be lit up either. When it begins to get dark, the automatic headlamp system will switch from DRL to the headlamps or the last chosen headlamp setting that was used. When you turn the headlamp switch off, the headlamps will go off, and your DRL lamps will illuminate, provided it is not dark outside. To idle an automatic transmission equipped vehicle with the DRL off, set the parking brake. Shifting the transmission into PARK (P) will also allow you to idle the vehicle with the DRL off. The DRL will stay off until you release the parking brake or shift the transmission out of PARK (P). To idle a manual transmission equipped vehicle with the DRL off, set the parking brake. The DRL will stay off until you release the parking brake.

Fog Lamps If your vehicle has fog lamps, use them for better vision in foggy or misty conditions.

The fog lamp button is located on the left side of your instrument panel.

Your parking lamps and/or low-beam headlamps must be on for your fog lamps to work. Press the button to turn the fog lamps on. Press the button again to turn them off. An indicator light will glow in the button when the fog lamps are on. Remember, fog lamps alone will not give off as much light as your headlamps. Never use the fog lamps in the dark without turning on the headlamps.

3-1 5

The fog lamps will go off whenever the high-beam headlamps come on. When the high beams go off, the fog lamps will come on again. The fog lamps will be cancelled after the ignition is turned off. If you still want to use the fog lamps after you restart the vehicle, you will need to press the fog lamp button again Auxiliary Roof Mounted Lamp Switch If your vehicle has this feature, this switch includes wiring provisions for a dealer or a qualified service center to install an auxiliary roof lamp.

Dual Automatic Climate Control System Your vehicle may have the optional dual automatic climate control system. With this system you can control the heating, cooling and ventilation for your vehicle.

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.

If your vehicle is equipped with the dual automatic climate control system, memory seats, and memory mirrors, 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

Press the up or down arrows on the fan switch, the defrost button, the AUTO button, or the air conditioning button to turn the system on when it is off. v (Mode): Press this button to manually select the air delivery mode to the floor, panel, or windshield outlets. This system will stay in the selected mode until the mode button is pressed again, or the AUTO button, defrost button, or the off button is pressed. Air delivery mode can be adjusted while the system is off. A five second status display will indicate the current mode. Display: In the full AUTO mode, the automatic dual climate control system display will show the driver set temperature and an arrow pointing to the driver’s side. An arrow pointing to the passenger’s side will display if both sides are set to the same temperature. If the temperature settings are not the same, the opposite side temperature

setting will be displayed for an additional five seconds. During the five second status display the current mode and blower speed will be displayed. Driver’s Side Temperature Knob: Turn this knob clockwise or counterclockwise to manually raise or lower the temperature on the driver’s side of the vehicle. The display will show the temperature setting decreasing or increasing and an arrow pointing to the driver. The temperature can be adjusted even if the system is turned off. If the passenger’s set temperature has not been adjusted this knob controls both the driver’s and passenger’s air temperature. The temperature to the rear seat area is controlled by using this knob. Passenger’s Side Temperature Knob: Turn this knob clockwise or counterclockwise to manually raise or lower the temperature on the passenger’s side of the vehicle. The display will show the temperature setting decreasing or increasing and an arrow pointing to the passenger. The temperature can be adjusted even if the system is turned off. Once this knob is used, the passenger’s temperature will remain independent of the driver’s until the AUTO button is pressed and held for approximately four seconds.

3-25

2. Set the driver’s and passenger’s temperature.

To find your comfort setting, start with a 74°F (23°C) temperature setting and allow about 20 minutes for the system to regulate. Turn the driver’s or passenger’s side temperature knob to adjust the temperature setting as necessary. If you choose the temperature setting of 60°F (1 5°C) the system will remain at the maximum cooling setting. If you choose the temperature setting of 90°F (32°C) the system will remain at the maximum heat setting. Choosing either maximum setting will not cause the vehicle to heat or cool any faster. Be careful not to cover the sensor located on the top of the instrument panel near the windshield. This sensor regulates air temperature based on sun load, and also turns on your headlamps. 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 engine coolant temperature. Pressing the fan switch will override this delay and change the fan to a selected speed.

Automatic Operation AUTO (Automatic): When automatic operation is active the system will control the inside temperature, the air delivery, and the fan speed. Use the steps below to place the entire system in automatic mode: 1. Press the AUTO button.

When AUTO is selected, the display will change to show the current driver’s set temperature, delivery mode and fan speed. Press the AUTO button again within five seconds to display the passenger’s set temperature. If the driver and passenger’s temperature settings are not the same, the opposite side temperature setting will be displayed for an additional five seconds. To make the passenger’s temperature the same as the driver’s press and hold the AUTO button for approximately four seconds. When auto is selected, the air conditioning operation and air inlet will be automatically controlled. The air conditioning compressor will run when the outside temperature is over approximately 40°F (4°C). The air inlet will normally be set to outside air. I f it’s hot outside, the air inlet may automatically switch to recirculate inside air to help quickly cool down your vehicle. The light on the button will illuminate in recirculation.

If the outside temperature is 40°F (4°C) or warmer, your air conditioning compressor will automatically run to help dehumidify the air and dry the windshield. Rear Window Defogger The lines you see on the rear window warm the glass. The rear window defogger uses a warming grid to remove fog from the rear window. @ (Rear): Press this button to turn the rear window defogger on or off. An indicator light in the button will come on to let you know that the rear window defogger is activated. The rear window defogger will turn off approximately 10 minutes after the button is pressed. If you need additional warming time, press the button again. If you vehicle is equipped with heated mirrors this button will activate them. 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 defogger and the repairs would not be covered by your warranty. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid.

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.

Outlet Adjustment

p'

Use the air outlets located in the center and on the side of your instrument panel to direct the airflow. Your vehicle has air outlets that allow you to adjust the direction and amount of airflow inside the vehicle. Move the louvers up or down. Use the thumbwheel next to or underneath the outlet to close the louvers. For the most efficient airflow and temperature control, keep the outlet in the fully opened position. If your vehicle is equipped with rear seat outlets they can be used to adjust airflow toward either seating area, the floor, or upward. Move the center louver up or down to direct the airflow.

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. 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 driver information system that works along with the warning lights and gages. See Driver Information Center (DE) on page 3-50.

3-30

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. To display the odometer reading with the ignition off, press the reset button. Engine Hour Meter Display The odometer can also display the number of hours the engine has run. To display the hour meter, turn the ignition off, press and hold the reset button for at least four seconds. The hour meter will be displayed for up to 30 seconds, or until the ignition is turned on. Tachometer Your tachometer displays the engine speed in revolutions per minute (rpm). 3-32

Notice: On vehicles with a manual transmission, if you operate the engine with the tachometer in the shaded warning areas, your vehicle’s engine or other parts of your vehicle could be damaged. Damage to your engine or vehicle caused by operating the engine with the tachometer in the shaded warning areas isn’t covered by your vehicle warranty. Don’t operate the tachometer in the shaded warning areas. 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

Air Bag Off Light

There is an air bag readiness light on the instrument panel cluster, 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 passenger sensing system (if equipped), the wiring and the crash sensing and diagnostic module. For more information on the air bag system, see Air Bag Systems on page 1-61.

When you turn the right front passenger’s air bag off, this light will be lit and stay lit 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 on page 1-68 for more on this, including important safety information. The AIR BAG OFF light will look like one of the following illustrations.

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.

In a crash, the air bag wouldn’t be able 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.

to

Canada without Passenger Sensing System

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.

CAUTION:

(Continued)

3-35

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 the 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.

3-36

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 Indicator - Canada

Status

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 passenger air bag status indicator, it means that the passenger sensing system or the air bag off switch has turned off the right front passenger’s air bag. See Passenger Sensing System on page 1-74 or Air Bag Off Switch on page 1-68 for more c his, including important safety information.

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 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.

If the r - It 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.

3-37

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.

Battery Warning Light

If this light is displayed when the engine is running, you may have a problem with your charging system.

If the air bat ~ f f 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 air bag. See ”Air Bag Readiness Light” in the Index.

The battery display will also stay on while the key is in RUN until the engine is started. If the light stays on after starting the engine it could indicate a problem with the generator drive belt, or some other charging system problem. Have it checked right away. Driving with this light displayed could drain your battery. If you must drive a short distance with this light displayed, it helps to turn off all your accessories, such as the radio and the air conditioner.

3-38

Voltmeter Gage

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. 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. Up-Shift Light

This light is used on some models with manual transmissions.

The shift indicator light will help you get the best fuel economy.

3-39

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 OD have the vehicle towed for service. See Towing Your Vehicle on page 4-53.

VE ? your brake system 1

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.

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. Ha inspected right away.

Anti-Lock Brake System Warning Light

Traction Off 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 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 3-40 earlier in this section.

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:

Engine Coolant Temperature Gage

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. 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.

~~

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 21 0°F (1 00°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 on page 5-36.

i

Tran'smission Temperature Gage

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 (1 30°C).

At approximately 265°F (13O"C), the driver information center 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 (127°C). See Driver Information Center (DIC) on page 3-50 for further information. If your vehicle has an Allison transmission, and the fluid reaches temperatures of approximately 275°F (1 35°C) or greater, the driver information center will display a TRANS HOT IDLE ENGINE warning message and a chime will sound until the temperature falls below 265°F (129°C) degrees. 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 265°F (1 29°C). If the transmission continues to operate above 265°F (130"C), contact your nearest dealer or the GM Roadside Assistance Center. See Roadside Assistance Program on page 7-6. 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.

3-43

The following situations can cause the transmission to operate at higher temperatures:

Towing a trailer Hot outside air temperatures Hauling a large or heavy load Low transmission fluid level High transmission fluid level 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 on page 6-5 for the proper transmission maintenance intervals.

3-44

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. This could lead to costly repairs that may not be covered by your warranty.

Notice: Modifications made to the engine, transmission, exhaust, intake or fuel system of your vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission controls and may cause this light to come on. Modifications to these systems could lead to costly repairs not covered by your warranty. This may also result in a failure to pass a required Emission Inspection/Maintenance test. 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. 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.

3-45

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. 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. 3-46

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. 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

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 3-60 -7d Engine Oil on page 5- 17.

Don’t 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: Damage to your engine from neglected oil problems can be costly and is not covered by your warranty.

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. When the fuel tank is low the Low Fuel message will appear. See Driver Information Center (DIC) on page 3-50.

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.

If you have a diesel engine, see Fuel Gage in the Diesel Engine Supplement. 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.
