{CAUTION:

If you leave your cruise control on when you are not using cruise, you might hit a button and go into cruise when you do not want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control.

1. Press the cruise control on/off button. 2. Get up to the desired speed. 3. Press and release the SET– button located on the

steering wheel.

4. Take your foot off the accelerator.

Resuming a Set Speed If cruise control is set at a desired speed and the brakes are applied, this shuts off the cruise control. However, it does not need to be reset. Once your vehicle reaches a speed of about 25 mph (40 km/h) or more, press the +RES button on the steering wheel. The vehicle goes back to the previously selected speed and stays there. Increasing Speed While Using Cruise Control To increase the cruise speed while using cruise control: (cid:127) Press and hold the +RES button on the steering wheel until you reach your new desired speed, then release it. To increase vehicle speed in small increments, press the +RES button. Each time this is done, the vehicle will go about 1 mph (1.6 km/h) faster.

(cid:127) Reducing Speed While Using Cruise Control To reduce your speed while using cruise control: (cid:127) Press and hold the SET– button on the steering wheel until you reach the desired lower speed, then release it. To slow down in very small amounts, press the SET– button on the steering wheel brieﬂy. Each time this is done, the vehicle will go about 1 mph (1.6 km/h) slower.

Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase vehicle speed. When you take your foot off the pedal, the vehicle will slow down to the cruise speed you set earlier.

Using Cruise Control on Hills How well the cruise control will work on hills depends upon the vehicle speed, load and the steepness of the hills. When going up steep hills, you might have to step on the accelerator pedal to maintain your speed. When going downhill, you might have to brake or shift to a lower gear to keep your speed down. If the brakes are applied the cruise control will turn off. Many drivers ﬁnd this to be too much trouble and do not use cruise control on steep hills. Ending Cruise Control There are three ways to end cruise control: (cid:127) Step lightly on the brake pedal. (cid:127) Press the [ button on the steering wheel. (cid:127) Press the T button on the steering wheel. Erasing Speed Memory The cruise control set speed memory is erased by turning off the cruise control or the ignition.

Daytime Running Lamps (DRL)/ Automatic Headlamp System 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. DRL lamps are required to function at all times on all vehicles ﬁrst sold in Canada. A light sensor on top of the instrument panel makes the DRL work, so be sure it is not covered. The DRL system will make the low-beam headlamps come on at reduced brightness when the following conditions are met:

The ignition is on. The exterior lamps control is off. The parking brake is released.

While the DRL are on, only the vehicle’s low-beam headlamps will be on at reduced brightness. The turn signal, taillamps, sidemarker, and other lamps will not be on. The instrument panel will not be lit up either.

3-14

(cid:127) (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) When it is dark enough outside, the DRL will turn off and the vehicle’s headlamps and parking lamps will turn on. The other lamps that come on with the headlamps will also come on. When it is bright enough outside, the headlamps will go off and the DRL will come on. To idle the vehicle with the DRL off, turn the exterior lamp control off and then do one of the following:

Turn the exterior lamp control to the parking lamp position. Turn the exterior lamp control to the headlamp position. Turn the exterior lamp control from AUTO to off and back to AUTO.

This feature is not available for vehicles ﬁrst sold in Canada. To turn off the automatic headlamp feature when it is dark outside, move the exterior lamp control to the parking lamp position. The parking lamps remain on and the headlamps turn off. The fog lamps also go on if they were on previously. As with any vehicle, the regular headlamp system should be turned on when needed.

Fog Lamps

If your vehicle has fog lamps, the button is located in the center of the exterior lamps control on the left side of the steering column.

Press the fog lamps button to turn the lamps on or off. While the high-beam headlamps are on, the fog lamps are off. Some localities have laws that require the headlamps to be on along with the fog lamps.

Exterior Lighting Battery Saver If the parking lamps or headlamps have been left on after the ignition has been turned to off, the exterior lamps will turn off after about 10 minutes. This protects the battery from being drained. Use the exterior lamp control to turn the lamps back on, if they are still needed.

Instrument Panel Brightness The instrument panel lights can be brightened or dimmed by pressing the center knob of the interior lamp controls until it pops out. Turn the knob clockwise to brighten the lights or counterclockwise to dim them.

Courtesy Lamps Courtesy lamps come on to make it easier to enter and exit the vehicle. These lamps will come on when the interior lamp control is in the door position and any door is opened.

Entry Lighting The courtesy lamps come on and stay on for a set time whenever the interior lamp control is in the door position and the UNLOCK button on the Remote Keyless Entry (RKE) transmitter is pressed. The lamps stay on while a door is opened and then turn off automatically about 25 seconds after it is closed. If the UNLOCK button is pressed and a door is not opened, the lamps will turn off after about 25 seconds. The courtesy lamps turn off when the ignition key is turned to ON/RUN or START. They will come on again when a door is opened.

Delayed Entry Lighting Delayed entry lighting lights the vehicle’s interior for a period of time after all the doors have been closed. After all the doors have been closed, the delayed entry lighting feature will continue to work until one of the following occurs:

The ignition is in ON/RUN. The doors are locked. 25 seconds has passed.

If during the illumination period a door is opened, the timed illumination period will be canceled and the interior lamps will remain on.

Theater Dimming This feature allows for a three to ﬁve second fade out of the courtesy lamps instead of immediate turn off.

Delayed Exit Lighting This feature can be programmed either on or off using the Driver Information Center. See DIC Vehicle Personalization on page 3-76 under INT (Interior) LIGHTS KEYS REMOVED. When activated, the interior will be lit for a short period of time after the ignition key is removed from the ignition.

The ignition must be off and the interior lamp control must be in the door position for delayed exit lighting to work. When the ignition key is removed, interior illumination will activate and remain on until one of the following occurs:

The ignition is in ON/RUN. The power door locks are activated. 25 seconds has passed.

If during the illumination period a door is opened, the timed illumination period will be canceled and the interior lamps will remain on.

Perimeter Lighting Perimeter lighting provides a period of exterior vehicle lighting. Perimeter lighting activates when the key is removed from the ignition or the vehicle is unlocked using the Remote Keyless Entry (RKE) transmitter. The amount of time the exterior lamps will remain on can be programmed using the Driver Information Center (DIC). See “EXIT LIGHT DELAY” under DIC Vehicle Personalization on page 3-76 for additional information.

(cid:127) (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) Overhead Console Reading Lamps Your vehicle may have reading lamps located on the overhead console. Press the lens to turn them on and off.

Rear Assist Handle Reading Lamps Your vehicle may have reading lamps located near the rear assist handles. Press the lens to turn them on and off.

Electric Power Management The vehicle has Electric Power Management (EPM) that estimates the battery’s temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery’s state of charge is low, the voltage is raised slightly to quickly put the charge back in. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gage or voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed.

The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. A high electrical load occurs when several of the following loads are on: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. EPM works to prevent excessive discharge of the battery. It does this by balancing the generator’s output and the vehicle’s electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, the Driver Information Center (DIC) message might display Battery Saver Active. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages on page 3-58.

3-18

Battery Run-Down Protection This helps prevent the vehicle’s battery from draining in case the interior courtesy lamps, reading lamps, trunk lamp, underhood lamp, glove box lamps, or sun visor vanity lamps, if equipped, are accidently left on. If any of these lamps are left on while the ignition is off, they will automatically turn off after 10 minutes. The lamps will not come back on again until one of the following occurs:

The ignition is turned on. The interior lamps control is turned off, then to door or on.

Accessory Power Outlet(s) The accessory power outlets enable power electrical equipment such as a cellular telephone or a CB radio to be used inside the vehicle. Your vehicle has 12-volt outlets. One outlet is located on the center console below the climate controls. There may be another outlet located inside the center storage console or in the ﬂip and fold console. Open the cover to use the outlet. Be sure to close the cover when the outlet is not in use.

Improper use of the power outlet can cause

Notice: Adding any electrical equipment to your vehicle may damage it or keep other components from working as they should. The repairs would not be covered by your warranty. Do not use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer/retailer before adding electrical equipment. Certain power accessory plugs may not be compatible to the power accessory outlet and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer/retailer. Notice: damage not covered by your warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only. Notice: Leaving electrical equipment plugged in for an extended period of time while the vehicle is off will drain the battery. Power is always supplied to the outlets. Always unplug electrical equipment when not in use and do not plug in equipment that exceeds the maximum 20 ampere rating. When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment.

Ashtray(s) and Cigarette Lighter Your vehicle may have a removable ashtray and cigarette lighter. The cigarette lighter may be located under the climate control system. The removable ashtray can be placed into the front console cupholder. Notice: items in the ashtray, hot cigarettes or other smoking materials could ignite them and possibly damage your vehicle. Never put ﬂammable items in the ashtray. To use the cigarette lighter, push it in all the way, and let go. When the heating element is ready, it will pop back out by itself. Notice: Holding a cigarette lighter in while it is heating will not allow the lighter to back away from the heating element when it is hot. Damage from overheating may occur to the lighter or heating element, or a fuse could be blown. Do not hold a cigarette lighter in while it is heating. Do not use equipment exceeding maximum amperage rating of 20 amperes.

Climate Controls

Climate Control System With this system you can control the heating, cooling and ventilation for your vehicle. If your vehicle has the remote start feature and it is activated, the climate control system will automatically cool the vehicle if the temperature is greater than 90°F (32°C) and heat the vehicle if the temperature is below 37°F (3°C). If the temperature is between 37°F (3°C) and 90°F (32°C), the last control setting selected when the engine was running will be used. Normal operation and the last setting of the climate control system will return after the key is turned to the ON/RUN position.

3-20

Use the right knob to select from the following modes: H (Vent): This mode directs outside air to the instrument panel outlets. If driving in city traffic, and the vehicle is stopped and idling, or the weather is hot, turning on the recirculation mode helps to prevent the air inside the vehicle from becoming stale. After ﬁve minutes recirculate will allow some outside air into the vehicle. ) (Bi-Level): This mode directs half of the air to the instrument panel outlets, and the remaining air to the ﬂoor outlets. Some air may be directed toward the windshield. Slightly cooler air is directed to the instrument panel outlets and warmer air is directed to the ﬂoor outlets. 6 (Floor): This mode directs most of the air to the ﬂoor outlets with some air directed toward the side window outlets and a little air directed to the windshield.

In this mode, the system will automatically use outside air. The air conditioning compressor will be engaged unless the outside temperature is 40°F (4°C) or below.

3-21

Operation

OFF: Turn the left knob to this position to turn the climate control system off. 9 (Fan): Turn the knob by this symbol, located on the left side of the climate control panel, clockwise or counterclockwise to increase or decrease the fan speed. The fan speed will be temporarily reduced between the transition to a new mode. The fan will resume the original speed when the transition to the new mode is complete.

Temperature Control: Turn the center knob clockwise or counterclockwise to increase or decrease the temperature inside your vehicle.

You can also select modes by using the following buttons: h (Recirculate): Press this button to recirculate cabin air through the vehicle. It can be used to help reduce the outside air and odors that enter your vehicle or to help heat or cool the air inside your vehicle quicker. An indicator light below the button will come on in this mode. Operation in this mode during periods of high humidity and cool outside temperatures may result in increased window fogging. If window fogging is experienced, select the defrost mode. To prevent the air inside the vehicle from becoming stale, after ﬁve minutes recirculate will allow some outside air into the vehicle. # (Air Conditioning): Press this button to turn the air conditioning system on or off. When this button is pressed, an indicator light below the button will come on to let you know the air conditioning is activated. Air conditioning can be selected in any mode as long as the fan switch is on. The indicator light will change with each button press even when conditions prevent operation. On hot days during the vehicle’s initial start-up, open the windows to let hot inside air escape; then close them. This helps to reduce the time it takes for the vehicle to cool down. It also helps the system to operate more efficiently.

3-22

For quicker cool down on hot days, do the following: 1. Select the vent air mode. 2. Select the recirculation mode. 3. Select the air conditioner. 4. Select the coolest temperature. 5. Select the highest fan speed. The air conditioning system removes moisture from the air, so you may sometimes notice a small amount of water dripping underneath your vehicle while idling or after turning off the engine. This is normal. Using these settings together for long periods of time may cause the air inside the vehicle to become too dry. To prevent this, after ﬁve minutes recirculate will allow some outside air into the vehicle. Defogging and Defrosting Fog on the inside of the vehicle is a result of high humidity causing moisture to condense on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to clear frost or fog from the windshield. Use the defog mode to clear the windows of condensation and to warm the vehicle’s occupants. Use the defrost mode to remove frost or condensation from the windshield quickly. See “Rear Window Defogger” later in this section for information on clearing the rear window of fog or ice.

Turn the right knob to select the defog or defrost mode. Do not drive the vehicle until all windows are clear. - (Defog): This mode directs half of the air to the windshield and the side window outlets and half to the ﬂoor outlets. When you select this mode, the system turns recirculation off and runs the air conditioning compressor unless the outside temperature is near or below freezing. Pressing the recirculation button will have no effect other than turning on the indicator light while in defog mode. 0 (Defrost): This mode directs most of the air to the windshield and the side window outlets, with some air directed to the ﬂoor outlets. When you select this mode, the system turns recirculation off and runs the air conditioning compressor unless the outside temperature is near or below freezing. Pressing the recirculation button will have no effect other than turning on the indicator light while in defrost mode.

Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. < (Rear): Press the button to turn the rear window defogger on or off. An indicator light below the button will come on to let you know that the rear window defogger is activated. The rear window defogger will only work when the ignition is in ON/RUN. The rear window defogger will stay on for about 20 minutes after the button is pressed. If turned on again, the defogger will only run for about 20 minutes before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. Do not drive the vehicle until all windows are clear. Notice: Do not use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, 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.

Warning Lights, Gages, and Indicators This part describes the warning lights and gages that may be on the 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 the 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 the 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 are 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 is 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 the warning lights and gages. They are a big help.

9. Remove the old air ﬁlter. 10. Install a new passenger compartment air ﬁlter. See Maintenance Replacement Parts on page 6-13 for the type of ﬁlter to use. Make sure it slides under the compartment retainers.

11. Reverse Steps 1 through 8. For best climate control performance, re-installation of a clean air ﬁlter is required.

The safety belt light will also come on and stay on for several seconds, then it will ﬂash for several more.

Tachometer Your tachometer displays the engine speed in revolutions per minute (rpm).

This chime and light is repeated if the driver remains unbuckled and the vehicle is in motion. If the driver’s belt is already buckled, neither the chime nor the light will come on.

3-32

Passenger Safety Belt Reminder Light Several seconds after the engine is started, a chime will sound for several seconds to remind the front passenger to buckle their safety belt. This would only occur if the passenger airbag is enabled. See Passenger Sensing System on page 1-62 for more information. The passenger safety belt light, located on the instrument panel, will come on and stay on for several seconds and then ﬂash for several more.

This chime and light are repeated if the passenger remains unbuckled and the vehicle is in motion.

Airbag Readiness Light There is an airbag readiness light on the instrument panel cluster, which shows the airbag symbol. The system checks the airbag’s electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the airbag sensor, the pretensioners, the airbag modules, the wiring and the crash sensing and diagnostic module. For more information on the airbag system, see Airbag System on page 1-54.

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

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

3-33

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

Passenger Airbag Status Indicator Your vehicle has the passenger sensing system. Your instrument panel has a has a passenger airbag status indicator.

When you start the vehicle, the passenger airbag status indicator will light ON and OFF for several seconds as a system check.

If you use remote start to start your vehicle from a distance, if equipped, you may not see the system check. Then, after several more seconds, the status indicator will light either ON or OFF to let you know the status of the right front passenger’s frontal airbag. If the word ON is lit on the passenger airbag status indicator, it means that the right front passenger’s frontal airbag is enabled (may inﬂate).

{CAUTION:

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

The airbag readiness light should ﬂash for a few seconds when you start the engine. If the light does not come on then, have it ﬁxed immediately. If there is a problem with the airbag system, an airbag Driver Information Center (DIC) message may also come on. See DIC Warnings and Messages on page 3-58 for more information.

3-34

{CAUTION:

{CAUTION:

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 airbag. A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inﬂates. This is because the back of the rear-facing child restraint would be very close to the inﬂating airbag. Do not use a rear-facing child restraint in the right front passenger’s seat if the airbag is turned on.

Even though the passenger sensing system is designed to turn off the right front passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is fail-safe, and no one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. We recommend that rear-facing child restraints be secured in the rear seat, even if the airbag is off.

If the word OFF is lit on the airbag status indicator, it means that the passenger sensing system has turned off the right front passenger’s frontal airbag. See Passenger Sensing System on page 1-62 for more on this, including important safety information.

3-35

If, after several seconds, both 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/retailer for service.

{CAUTION:

If the airbag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger’s seat may not have the protection of the airbag(s). See Airbag Readiness Light on page 3-33 for more on this, including important safety information.

Charging System Light

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

That is normal. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If the ABS light stays on, turn the ignition off, if the light comes on when you are driving, stop as soon as it is safely possible and turn the ignition off. Then start the engine again to reset the system. If the ABS light still stays on, or comes on again while you are driving, your vehicle needs service. If the regular brake system warning light is not on, your vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, your vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 3-37.

3-38

If this warning light comes on and stays on, there may be a problem with the TCS and, if your vehicle has this feature, the StabiliTrak® system.

The TCS warning light will come on brieﬂy when the engine is started. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. This light will also come on when the traction control button is pressed disabling the system. If the TCS warning light stays on or comes on while you are driving, pull off the road as soon as possible and stop carefully. Try resetting the system by turning the ignition off then back on. If the light still stays on or comes back on again while you are driving, your vehicle needs service.

See DIC Warnings and Messages on page 3-58 for more information. Stop and check your tires as soon as it is safe to do so. If underinﬂated, inﬂate to the proper pressure. See Tires on page 5-63 for more information. When the Light Flashes First and Then is Solid This indicates that there may be a problem with the Tire Pressure Monitor System. The light ﬂashes for about a minute and stays on solid for the remainder of the ignition cycle. This sequence will repeat with every ignition cycle. See Tire Pressure Monitor System on page 5-71 for more information.

This light comes on brieﬂy when the engine is started and provides information about tire pressures and the Tire Pressure Monitoring System.

3-41

Malfunction Indicator Lamp Check Engine Light A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors operation of the fuel, ignition, and emission control systems. It makes sure 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 an OBD II problem and service is required.

Malfunctions often are indicated by the system before any problem is apparent. This can prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction.

If you keep driving your vehicle with this

Notice: light on, after a while, the emission controls might not work as well, your vehicle’s fuel economy might not be as good, and the engine might not run as smoothly. This could lead to costly repairs that might 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 can cause this light to come on. Modiﬁcations to these systems could lead to costly repairs not covered by your warranty. This could also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modiﬁcations on page 5-3.

3-42

This light comes on, as a check to show it is working, when the ignition is turned ON/RUN but the engine is not running. If the light does not come on, have it repaired. This light also comes on during a malfunction in one of two ways:

Light Flashing — A misﬁre condition has been detected. A misﬁre increases vehicle emissions and could damage the emission control system on your vehicle. Diagnosis and service might be required. Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service might be required.

If the Light is Flashing The following can prevent more serious damage to your vehicle: (cid:127) Reduce vehicle speed. (cid:127) Avoid hard accelerations. (cid:127) Avoid 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 the vehicle. Turn the ignition 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 see your dealer/retailer for service as soon as possible. If the Light Is On Steady You might 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 the Tank on page 5-8. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap allows 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 vehicle’s electrical system might be wet. The condition is usually corrected when the electrical system dries out. A few driving trips should turn the light off.

3-43

(cid:127) (cid:127) (cid:127) 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 causes the engine not to run as efficiently as designed. You might 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 might 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, your dealer/retailer can check the vehicle. Your dealer/retailer has the proper test equipment and diagnostic tools to ﬁx any mechanical or electrical problems that might have developed.

Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or might 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 the battery or if the battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This can 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, your dealer/retailer can prepare the vehicle for inspection.

If the light comes on, see your dealer/retailer for service as soon as possible.

Fuel Gage

The fuel gage indicates about how much fuel is left in the fuel tank when the ignition is on.

When the indicator nears empty, there is still a little fuel left, but you should get more fuel soon.

Here are four things that some owners ask about. All these things are normal and do not indicate that anything is wrong with the fuel gage: (cid:127) At the gas station, the pump shuts off before the

gage reads full. It takes more, or less, fuel to ﬁll up than the gage reads. For example, the gage reads half full, but it took more, or less, than half of the tank’s capacity to ﬁll it. The gage pointer may move while cornering, braking or accelerating. The gage may not indicate empty when the ignition is turned off.

Low Fuel Warning Light Your vehicle may have a low fuel light. It is a circle located on the fuel gage and will come on and a chime will sound periodically when the vehicle is low on fuel. The light will go off when fuel is added to the fuel tank. It will also come on for a few seconds when the ignition is turned on as a check to indicate it is working. If it does not come on then, have it ﬁxed. For vehicles with a Driver Information Center (DIC), a LOW FUEL message will appear. See DIC Warnings and Messages on page 3-58 for more information.

(cid:127) DIC Compass (Uplevel Only) Your vehicle may have a compass in the Driver Information Center (DIC). Compass Zone The zone is set to zone eight upon leaving the factory. Your dealer/retailer will set the correct zone for your location. Under certain circumstances, such as during a long distance cross-country trip or moving to a new state or province, it will be necessary to compensate for compass variance by resetting the zone through the DIC if the zone is not set correctly. Compass variance is the difference between the earth’s magnetic north and true geographic north. If the compass is not set to the zone where you live, the compass may give false readings. The compass must be set to the variance zone in which the vehicle is traveling. To adjust for compass variance, use the following procedure:

3-56

Compass Variance (Zone) Procedure 1. Do not set the compass zone when the vehicle is

moving. Only set it when the vehicle is in PARK (P). Press the option button until COMPASS ZONE displays.

2. Find the vehicle’s current location and variance

zone number on the map. Zones 1 through 15 are available.

3. Press the set/reset button to scroll through and

select the appropriate variance zone.

4. Press the trip or fuel button until the vehicle

heading, for example, N for North, is displayed in the DIC.

5. If calibration is necessary, calibrate the compass. See “Compass Calibration Procedure” following.

Compass Calibration The compass can be manually calibrated. Only calibrate the compass in a magnetically clean and safe location, such as an open parking lot, where driving the vehicle in circles is not a danger. It is suggested to calibrate away from tall buildings, utility wires, manhole covers, or other industrial structures, if possible. If CAL should ever appear in the DIC display, the compass should be calibrated. If the DIC display does not show a heading, for example, N for North, or the heading does not change after making turns, there may be a strong magnetic ﬁeld interfering with the compass. Such interference may be caused by a magnetic CB or cell phone antenna mount, a magnetic emergency light, magnetic note pad holder, or any other magnetic item. Turn off the vehicle, move the magnetic item, then turn on the vehicle and calibrate the compass.

To calibrate the compass, use the following procedure: Compass Calibration Procedure 1. Before calibrating the compass, make sure the

compass zone is set to the variance zone in which the vehicle is located. See “Compass Variance (Zone) Procedure” earlier in this section. Do not operate any switches such as window, sunroof, climate controls, seats, etc. during the calibration procedure.

2. Press the option button until COMPASS

CALIBRATION displays.

3. Press the set/reset button to start the compass

calibration.

4. The DIC will display CALIBRATION BEGUN DRIVE

IN CIRCLES. Drive the vehicle in tight circles at less than 5 mph (8 km/h) to complete the calibration. The DIC will display CALIBRATION FINISHED for a few seconds when the calibration is complete. The DIC display will then return to COMPASS CALIBRATION.
