# (Fog lamps) (If Equipped): Push the fog lamps button to turn them on and off. See Fog Lamps on page 3-15 for additional information.

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.

(cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) 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 For vehicles with fog lamps, the button is located in the center of the exterior lamps control on the left side of the steering column.

# : Press 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.

3-16

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 3-74 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.

3-17

(cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) 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 3-74 for additional information.

Overhead Console Reading Lamps The vehicle may have reading lamps located on the overhead console. Press the lens to turn them on and off.

Rear Assist Handle Reading Lamps The 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 bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gage or a 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.

3-18

A high electrical load occurs when several of the following are on, such as: 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, a Driver Information Center (DIC) message might be displayed, such as BATTERY SAVER ACTIVE, BATTERY VOLTAGE LOW, or LOW BATTERY. 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 3-56.

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.

3-19

(cid:129) (cid:129) Accessory Power Outlet(s) The accessory power outlets enable power electrical equipment, such as a cellular telephone. The 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. Notice: Adding any electrical equipment to the vehicle can damage it or keep other components from working as they should. The repairs would not be covered by the vehicle warranty. Do not use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer/retailer before adding electrical equipment.

Improper use of the power outlet can cause

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 the 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.

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 the heating, cooling and ventilation can be controlled. For vehicles with the remote start feature and it is activated, the climate control system automatically cools the vehicle if the temperature is greater than 90°F (32°C) and heats 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.

3-21

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

Air Delivery Mode Control: Turn clockwise or counterclockwise to change the direction of the airﬂow inside the vehicle. Select from the following air delivery modes: H (Vent): Air is directed 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): Air is divided between the instrument panel and 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): Air is directed to the ﬂoor outlets, with some air directed toward the side window outlets and windshield.

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

(cid:129) Warning Lights, Gages, and Indicators 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 prevent injury. Warning lights come on when there may be or is a problem with one of the vehicle’s functions. Some warning lights come on brieﬂy when the engine is started to indicate they are working. Gages can indicate when there may be or is a problem with one of the vehicle’s functions. Often gages and warning lights work together to indicate a problem with the vehicle. When one of the warning lights comes on and stays on while driving, or when one of the gages shows there may be a problem, check the section that explains what to do. Follow this manual’s advice. Waiting to do repairs can be costly and even dangerous.

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.

Passenger Safety Belt Reminder Light Several seconds after the engine is started, a chime sounds for several seconds to remind the front passenger to buckle their safety belt. This only occurs if the passenger airbag is enabled. See Passenger Sensing System on page 1-61 for more information. The passenger safety belt light, located on the instrument panel, comes on and stays on for several seconds and then ﬂashes for several more.

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

The airbag readiness light ﬂashes for a few seconds when the engine is started. If the light does not come on then, have it ﬁxed immediately.

If the passenger safety belt is buckled, neither the chime nor the light comes on. The front passenger safety belt warning light and chime may turn on if an object is put on the seat such as a briefcase, handbag, grocery bag, laptop or other electronic device. To turn off the warning light and or chime, remove the object from the seat or buckle the safety belt. Airbag Readiness Light The system checks the airbag’s electrical system for possible malfunctions. If the light stays on it indicates 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 1-53.

{ CAUTION:

If the airbag readiness light stays on after the vehicle is started or comes on while driving, it means the airbag system might not be working properly. The airbags in the vehicle might not inﬂate in a crash, or they could even inﬂate without a crash. To help avoid injury, have the vehicle serviced right away.

If there is a problem with the airbag system, an airbag Driver Information Center (DIC) message can also come on. See DIC Warnings and Messages on page 3-56
for more information.

Antilock Brake System (ABS) Warning Light

For vehicles with the Antilock Brake System (ABS), this light comes on brieﬂy when the engine is started.

If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the ABS light stays on, turn the ignition off. If the light comes on while 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 stays on, or comes on again while driving, the vehicle needs service. If the regular brake system warning light is not on, the vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, the vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 3-35. For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-56 for all brake related DIC messages.

Traction Control System (TCS) Warning Light

Your vehicle has a Traction Control System (TCS) warning light.

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. Have the traction control system and, if your vehicle has this feature, the StabiliTrak® system

inspected as soon as possible. See Traction Control System (TCS) on page 4-7 and StabiliTrak® System on page 4-6 for more information. Enhanced Traction System Warning Light

(cid:129) (cid:129) Engine Coolant Temperature Warning Light

This light comes on brieﬂy while starting the vehicle.

Engine Coolant Temperature Gage

The vehicle has a gage that shows the engine coolant temperature.

If it does not, have the vehicle serviced by the dealer/retailer. If the system is working normally the indicator light goes off. Notice: Driving with the engine coolant temperature warning light on could cause the vehicle to overheat. See Engine Overheating on page 5-31. The vehicle’s engine could be damaged, and it might not be covered by the vehicle warranty. Never drive with the engine coolant temperature warning light on. The engine coolant temperature warning light comes on when the engine has overheated. If this happens pull over and turn off the engine as soon as possible. See Engine Overheating on page 5-31
for more information.

3-38

If the gage pointer moves towards the H, the engine is too hot. This reading indicates the same thing as the warning light. It means that the engine coolant has overheated. If the vehicle has been operating under normal driving conditions, pull off the road, stop the vehicle, and turn off the engine as soon as possible. See Engine Overheating on page 5-31.

Low Coolant Warning Light

If your vehicle has this light, it comes on brieﬂy when you turn your ignition on as a bulb check only.

Tire Pressure Light

For vehicles with a tire pressure light, this light comes on brieﬂy when the engine is started and provides information about tire pressures and the Tire Pressure Monitoring System.

When the Light is On Steady This indicates that one or more of the tires is signiﬁcantly underinﬂated. A tire pressure message in the Driver Information Center (DIC), can accompany the light. See DIC Warnings and Messages on page 3-56 for more information. Stop and check the tires as soon as it is safe to do so. If a tire is underinﬂated, inﬂate to the proper pressure. See Tires on page 5-54 for more information. When the Light Flashes First and Then is On Steady This indicates that there could be a problem with the Tire Pressure Monitor System. The light ﬂashes for about a minute and stays on steady for the remainder of the ignition cycle. This sequence repeats with every ignition cycle. See Tire Pressure Monitor System on page 5-62
for more information.

3-39

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 ensures that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment.

This light should come on when the ignition is on, but the engine is not running, as a check to show it is working. If it does not, have the vehicle serviced by your dealer/retailer.

If the check engine light comes on and stays on, while the engine is running, this indicates that there is an OBD II problem and service is required.

Malfunctions often are indicated by the system before any problem is apparent. Being aware of the light can prevent more serious damage to the vehicle. This system assists the service technician in correctly diagnosing any malfunction. Notice: If the vehicle is continually driven with this light on, after a while, the emission controls might not work as well, the 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 the vehicle warranty. Notice: Modiﬁcations made to the engine, transmission, exhaust, intake, or fuel system of the vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect the vehicle’s emission controls and can cause this light to come on. Modiﬁcations to these systems could lead to costly repairs not covered by the vehicle warranty. This could also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modiﬁcations on page 5-3.

3-40

This light 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 the vehicle. Diagnosis and service might be required.

To prevent more serious damage to the vehicle: (cid:129) Reduce vehicle speed. (cid:129) Avoid hard accelerations. (cid:129) Avoid steep uphill grades.

If towing a trailer, reduce the amount of cargo being hauled as soon as it is possible.

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 key off, wait at least 10 seconds, and restart the engine. If the light is still ﬂashing, follow the previous steps and see your dealer/retailer for service as soon as possible.

Light On Steady: An emission control system malfunction has been detected on the vehicle. Diagnosis and service might be required.

An emission system malfunction might be corrected by doing the following: (cid:129) Make sure the fuel cap is fully installed. 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. If the vehicle has been driven through a deep puddle of water, the 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.

(cid:129) Make sure to fuel the vehicle with quality fuel. Poor

fuel quality causes the engine not to run as efficiently as designed and can cause: stalling after start-up, stalling when the vehicle is changed into gear, misﬁring, hesitation on acceleration, or stumbling on acceleration. These conditions might go away once the engine is warmed up. If one or more of these conditions occurs, change the fuel brand used. It will require at least one full tank of the proper fuel to turn the light off. See Gasoline Octane on page 5-6.

If none of the above have made the light turn off, your dealer/retailer can check the vehicle. The dealer/retailer has the proper test equipment and diagnostic tools to ﬁx any mechanical or electrical problems that might have developed.

3-41

(cid:129) (cid:129) Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or might begin programs to inspect the emission control equipment on the vehicle. Failure to pass this inspection could prevent getting a vehicle registration. Here are some things to know to help the vehicle pass an inspection:

The vehicle will not pass this inspection if the check engine light is on with the engine running, or if the key is in ON/RUN and the light is not on. The vehicle will not pass this inspection if the OBD II (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 the battery has recently been replaced 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 this has been done and the vehicle still does not pass the inspection for lack of OBD II system readiness, your dealer/retailer can prepare the vehicle for inspection.

3-42

Oil Pressure Light

{ CAUTION:

Do not keep driving if the oil pressure is low. The engine can become so hot that it catches ﬁre. Someone could be burned. Check the oil as soon as possible and have the vehicle serviced.

Notice: Lack of proper engine oil maintenance can damage the engine. The repairs would not be covered by the vehicle warranty. Always follow the maintenance schedule in this manual for changing engine oil.

(cid:129) (cid:129) This light comes on brieﬂy while starting the engine. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the light comes on and stays on, it means that oil is not ﬂowing through the engine properly. The vehicle could be low on oil and it might have some other system problem.

Fuel Gage

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

An arrow on the fuel gage indicates the side of the vehicle the fuel door 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:129) 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.

3-46

(cid:129) (cid:129) (cid:129) 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 3-56 for more information.

Check Gas Cap Light

Compass Calibration The compass can be manually calibrated. To calibrate the compass through the DIC, see DIC Compass (Uplevel Only) on page 3-54.

3-53

(cid:129) 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: 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.

3-54

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.
