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.


D Move the cruise switch from ON to R/A. 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 R/A briefly. Each time you do this, your vehicle will go about 1 mph (1.6 km/h) faster.


Reducing Speed While Using Cruise Control D Press and hold the SET button at the end of the lever


until you reach the lower speed you want, then release it.


D 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.


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 either the cruise control: D Step lightly on the brake pedal. D 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.

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. To idle your vehicle with the automatic headlamp system off, set the parking brake while the ignition is off. Then start your vehicle. The automatic headlamp system will stay off until you release the parking brake.


2-44


As with any vehicle, you should turn on the regular headlamp system when you need it. You may be able to turn off your Automatic Headlamp System. See “Daytime Running Lamps (DRL)” later in this section for more information. Lamps On Reminder A reminder chime will sound when your headlamps or parking lamps are manually turned on and your ignition is in OFF, LOCK or ACCESSORY. To disable the chime, turn the thumbwheel all the way down. In the automatic mode, the headlamps turn off once the ignition key is in OFF. 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 lights are required on all vehicles first sold in Canada.


The DRL system will come on when: D the ignition is on, D the headlamp switch is in automatic headlamp mode, D the automatic transmission is not in PARK (P), D the light sensor determines it is daytime and D the parking brake is released. 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). This procedure applies only to vehicles first sold in the United States.


When necessary, you may turn off the Automatic Headlamp System and the Daytime Running Lamps (DRL) feature by following these steps. When the system is turned off, the headlights will not automatically come on when it becomes dark outside. As with any vehicle, you should turn on the regular headlamp system when you need it. 1. Turn the ignition to RUN. 2. Press the DOME OVERRIDE button four times within six seconds. After the fourth press of the button, a chime will sound informing you the system is off. The system will revert back to the automatic mode when the ignition is turned off and on again.


3. To return to the automatic mode, push the


DOME OVERRIDE button four times within six seconds (the chime will sound), or turn the ignition off and on again.

Do not spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing.


Compass Calibration The compass may need calibration if: D After five seconds, the display does not show a compass heading (“N” for North, for example), there may be a strong magnetic field interfering with the compass. Such interference may be caused by a magnetic antenna mount, magnetic note pad holder or a similar magnetic item.


D The compass does not display the correct heading


and the compass zone variance is set correctly.


In order to calibrate, the letters “CAL” must be displayed in the mirror compass windows. If “CAL” is not displayed, push in the “COMP” button for approximately eight seconds or until the letter “CAL” is displayed. The compass can be calibrated in one of two ways: D Drive the vehicle in circles at five mph (8 km/h) or


less until the display reads a direction, or


D Drive the vehicle on your everyday routine and after several turns the compass will become calibrated and will display a direction.


2-50


Compass Variance The mirror is set in zone eight upon leaving the factory. It will be necessary to adjust the compass to compensate for compass variance if you live outside zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. Compass variance is the difference between earth’s magnetic north and true geographic north. If not adjusted to account for compass variance, your compass could give false readings. To adjust for compass variance: 1. Use the COMP button located at the bottom of


the mirror.


2. Press and hold the COMP button for three seconds


until a zone number appears in the display.


3. Find your current location and variance zone number

This device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.


Changes and modifications to this system by other than an authorized service facility could void authorization to use this equipment. Programming the Transmitter Do not use the HomeLinkR Transmitter with any garage door opener that does not have the “stop and reverse” feature. This includes any garage door opener model manufactured before April 1, 1982. Be sure that people and objects are clear of the garage door you are programming. Your vehicle’s engine should be turned off while programming the transmitter. Follow these steps to program up to three channels: 1. If you have previously programmed a transmitter channel, proceed to Step 2. Otherwise, hold down the two outside buttons on the HomeLink Transmitter until the indicator light begins to flash rapidly (after 20 seconds). Then release the buttons. This procedure initializes the memory and erases any previous settings for all three channels.


2. Decide which one of the three channels you want to program. Hold the end of the hand-held transmitter about 2 to 5 inches (5 to 13 cm) away from the surface of the HomeLink Transmitter so that you can still see the indicator light.


3. Using both hands, press the hand-held transmitter


button and the desired button on the HomeLink Transmitter. Continue to press both buttons through Step 4.


4. Hold down both buttons until you see the light on the HomeLink Transmitter flash rapidly. The rapid flashing indicates that the HomeLink Transmitter has been programmed. Release both buttons once the light starts to flash rapidly.


If you have trouble programming the HomeLink Transmitter, make sure that you have followed the directions exactly as described and that the battery in the hand-held transmitter is not dead. If you still cannot program it, turn the hand-held transmitter end over end and try again. The HomeLink Transmitter may not work with older garage door openers that do not meet current Federal Consumer Safety Standards. If you cannot program the transmitter after repeated attempts, refer to “Training a Garage Door Opener with Rolling Codes” later in this section or contact the manufacturer of the unit at 1-800-355-3515. Be sure to keep the original hand-held transmitter in case you need to erase and reprogram the HomeLink Transmitter.


2-61


Canadian Owners: During programming, the hand-held transmitter may automatically stop transmitting after one or two seconds. In this case, you should press and re-press the button on the hand-held transmitter every two seconds without ever releasing the button on the HomeLink Transmitter. Release both buttons when the indicator light on the HomeLink Transmitter begins to flash rapidly. Operating the Transmitter Press and hold the appropriate button on the HomeLinkR Transmitter. The indicator light comes on while the signal is being transmitted. If the hand-held transmitter appears to program the HomeLink Transmitter but does not open your garage door, and if the garage door opener was manufactured after 1996, the garage door opener may have a “rolling code” system. A rolling code system changes the code of the garage door opener every time you open or close the garage door. To determine if you have this system, press the button on the HomeLink Transmitter that you have programmed already. If the indicator light flashes rapidly for one to two seconds, then turns solid, the garage door opener has a rolling code system. In a rolling code system, the garage door motor head unit must be trained to the HomeLink Transmitter. 2-62


Training a Garage Opener with a “Rolling Code” Feature (If Equipped) If you have not previously programmed the hand-held transmitter to the HomeLinkR Transmitter, see “Programming the Transmitter” listed previously. If you have completed this programming already, you now need to train the garage door opener motor head unit to recognize the HomeLink Transmitter. Refer to your garage door opener owner’s manual for the proper transmitter training procedure for your garage door opener brand. 1. Find the training button on the garage door opener motor head unit. The exact location and color will vary by garage door opener brand. If you have difficulty finding the training button, refer to your garage door opener owner’s manual. Because of the steps involved, it may be helpful to have another person assist in programming the transmitter.


2. Press the training button on the garage door


opener motor head unit. An indicator light will begin to flash when the motor head unit enters the training mode. Following this step, you have 30 seconds to start Step 3.


3. Return to the HomeLink Transmitter in your vehicle


and firmly press and release the HomeLink Transmitter button you have already programmed for two to three seconds. Press and release the button again (you may need to do this step up to three times) to make sure that the HomeLink Transmitter has been trained to the garage door opener motor head unit. Check that the training was successful. The motor head unit indicator light should no longer be flashing.


The garage door opener should now recognize the HomeLink Transmitter. You may either use the HomeLink Transmitter or the hand-held transmitter to open the garage door. If after following these instructions, you still have problems training the garage door opener, call the manufacturer of the unit at 1-800-355-3515. Erasing Channels To erase all three programmed channels, hold down the two outside buttons until the indicator light begins to flash (after 20 seconds). Release both buttons. Accessories Accessories for the HomeLinkR Transmitter are available from the manufacturer of the unit. If you would like additional information, please call 1-800-355-3515.

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.


2-69


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 “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.


2-70


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” 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.


2-71


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. 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.


2-72


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.


2-73


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.


2-74


Engine Coolant Temperature Gage


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. The “Problems on the Road,” section of this manual shows what to do. See “Engine Overheating” in the Index.


Transmission Temperature Gage (If Equipped)


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.


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.


2-75


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.


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 Assist System is active. Slippery road conditions may exist if the LOW TRACTION light comes on, so adjust your driving accordingly.


2-76


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 TRACTION OFF 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 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.


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


will come on and stay on to indicate that the Traction Assist 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, Traction Assist System 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.


2-77


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.


2-78


NOTICE:


Modifications made to the engine, transmission, exhaust 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.


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.


2-79


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. 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.


2-80


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.


2-81


Oil Pressure Gage


CAUTION:


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.


United States


Canada


NOTICE:


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


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 “Check Eng Oil Pressure” and “Engine Oil” in the Index.

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 of fuel, and you should get more fuel as soon as possible.


2-84


Here are some situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage. D At the gas station, the fuel pump shuts off before the


gage reads full.


D 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.


D The gage goes back to empty when you turn off


the ignition.


Message Center The message center is located on the left side of the instrument panel cluster. It gives you important safety and maintenance facts. When you turn the ignition on, the entire center lights up for just a few seconds. As needed, the message center will display one of the following messages. The message center is capable of alternating among different messages if needed.


Battery


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


The battery display will also stay on while the key is in RUN until the engine is started. If the message 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 message displayed could drain your battery. If you must drive a short distance with this message displayed, it helps to turn off all your accessories, such as the radio and the air conditioner. Trans Fluid Hot If you have an automatic transmission, you have a transmission temperature warning display contained in the message center.


If the transmission fluid temperature becomes high, the message center will display this message.


When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. When the transmission fluid temperature returns to normal, the display will turn off and the transmission shifting patterns will return to normal.


NOTICE:

the system to use outside air. This is the setting which should be used for normal operation. Pressing the OUTSIDE AIR button will cancel the RECIRCULATION button.


RECIRCULATION: Press this button to


limit the amount of outside air entering your vehicle. This is helpful when you are trying to limit odors entering your vehicle or attempting to quickly cool down the interior. Pressing RECIRCULATION will recirculate air continuously. RECIRCULATION is used when the fan control is OFF to limit odors, outside air and dust from entering your vehicle. All button lights will go off. The last setting selected will activate when the blower is turned back on. Pressing the RECIRCULATION button will cancel the OUTSIDE AIR button. To return to normal operation and to prevent stale air, be sure to return the OUTSIDE AIR. 3-4


Between HEATER and BLEND mode, outside air is forced to reduce window fogging. If the RECIRCULATION button is pressed, the LED indicator will flash three times indicating that forced outside air is activated and RECIRCULATION is not available. The auto recirculation feature will activate when the following are true: D the air conditioning system is activated, D the OUTSIDE AIR button is on, and D the vehicle load is high due to city traffic, extended


idling or hot weather.


The system will automatically switch to the recirculation mode to lower the system load and improve interior comfort. The OUTSIDE AIR and RECIRCULATION button LEDs will not change. The system will return to the OUTSIDE AIR function when the system load is reduced.


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. Air conditioning will be automatically disabled when the outside temperature drops below a level at which air conditioning is effective.


Electronic Climate Control System (If Equipped)


Fan Control The knob on the left side of the electronic climate control panel controls the fan speed. To manually increase airflow, move the knob clockwise. To manually decrease airflow, move it counterclockwise. OFF: If the knob is in OFF, outside air will still enter the vehicle, and will be directed based on the position of the mode knob. AUTO: If the knob is in AUTO, the fan speed will vary as the system maintains the selected temperature.


When both the fan control and mode knobs are in the AUTO position, the system will then automatically maintain the desired cabin temperature as selected by the temperature knob. Manual control of functions is also available.


Temperature Knob The middle knob on the control panel lets you select the desired air temperature in your vehicle. This knob will allow you to adjust the interior air temperature independent of the function knob setting. Move the knob clockwise toward 82 for warmer air. Move the knob counterclockwise toward 66 for cooler air. When the system is set for automatic operation, sensors will control the fan/blower 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 - 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 air 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 blower fan speed will gradually increase and air will flow from the heater 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.

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 operations yourself, or let the system work for you by placing the system in AUTO mode. See “Mode Knob - Automatic Operation” earlier in this section.


PANEL: This setting directs most of the air


through the instrument panel outlets and a small amount through the floor outlets.


BI-LEVEL: Air is delivered through the heater


floor outlets as well as the instrument panel outlets.


HEATER: This setting directs most of the warmed air through the heater floor outlets and some air through the windshield defroster outlets.


BLEND: Airflow is divided equally between the heater floor outlet and the windshield defroster outlets. The air conditioning compressor may run to dehumidify the air to prevent window fogging.


DEFROST: This setting directs most air through the windshield defroster outlets and some through the heater outlets. The air conditioning compressor may run to dehumidify the air to prevent window fogging.


OUTSIDE AIR: Press this button to force the system to use outside air. Press it again to close off the outside air. Pressing the OUTSIDE AIR button will cancel the RECIRCULATION button.


RECIRCULATION: Press this button to limit the amount of outside air entering your vehicle. This is helpful when you are trying to limit odors entering your vehicle or attempting to quickly cool down the interior. In the AUTO mode, the system will use recirculation as necessary to cool the air. Pressing the recirculation button will change the operation to a manual mode and the air will recirculate non-stop. 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 temperature drops below a level at which air conditioning is ineffective. Remember that in order for the automatic system to perform well, it needs A/C to provide cooling performance. Rear Air Conditioning and Heating Systems (If Equipped) If your vehicle has one of these systems, you can increase and decrease the airflow at the rear vents. Depending on the system you have and the setting selected, you can send cooled or heated air to the rear of the vehicle.


Rear Air Conditioning (Without Rear Heater) (If Equipped)


To increase and decrease the flow of cooled air to the rear vents, turn the knob to the blower speed you want. The knob has three speed positions. To increase the flow of cooled air, turn the switch toward “3”. To decrease the flow of cooled air, turn it toward “1”. To turn the fan off, turn the knob to OFF. To operate the rear system using the front control, just turn the knob to the blower position you want.


Rear Control


To use the rear control, first turn the front control to REAR. Then, the rear control can be used to increase and decrease the airflow.


Front Control

Rear Air Conditioning and Rear Heater (If Equipped) If your vehicle has the rear air conditioning and rear heater system combination, controls are provided to regulate temperature, location and fan speed.


Generally, the upper vents are used for air conditioning and the floor vents for heating. The control knob can be set to any blend setting. To adjust the air temperature, turn the temperature knob on the center of the control panel. For warmer air, turn the knob clockwise toward red. For cooler air, turn the knob counterclockwise toward blue.


Front Control


To adjust the airflow speed, turn the fan control knob located on the left side to the desired setting. To activate the second seat control system, turn the fan knob on the front overhead control to REAR. To regulate the airflow location, adjust the right control on the control. Turn the knob clockwise for floor vent airflow or counterclockwise for headliner vent airflow.


Rear Control


The rear control works just like the front control. It will allow second seat passengers to adjust the controls as they desire. To use the rear control, first turn the front control knob to REAR.

With this system the rear passengers can control the temperature of the air flow for his/her own zones. The climate control has three controls. To adjust the airflow speed, turn the fan control knob located on the left side of the control panel to the desired blower setting. The system also has a front AUTO setting that can automatically change the temperature of the rear seating area based on information from the front control. An OFF setting, located on the front climate control panel, also allows the driver to turn off the rear passenger seat controls from the front seat. To adjust the air temperature, turn the temperature knob on the center of the control panel. For warmer air, turn the knob clockwise toward 82_F (28_C). Turn the knob counterclockwise toward 66_F (19_C) for cooler air. To regulate the airflow location, adjust the right knob on the control panel. Turn the knob clockwise for floor vent airflow or counterclockwise for headliner vent airflow. Generally, the upper vents are used for air conditioning and the floor vents for heating. The control knob can be set to any blend setting. For rear control operation, use the above instructions.


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 HEATER 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.


3-11


Heating The heater works best if you keep your windows closed while using it. On cold days, use the HEATER or VENT/HEAT 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 DEFOG 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)
