So, do not use the cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. With cruise control, a speed of about 25 mph (40 km/h) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about 25 mph (40 km/h). When the brakes are applied, cruise control is turned off. If the vehicle has StabiliTrak®, and the system begins to limit wheel spin, cruise control will automatically disengage. See StabiliTrak® System on page 5-5. When road conditions allow the cruise control to be safely used again, it can be turned back on. The cruise control buttons are located on left side of the steering wheel. Setting Cruise Control Cruise control will not work if the parking brake is set, or if the master cylinder brake ﬂuid level is low. The cruise control light on the instrument panel cluster comes on after the cruise control has been set to the desired speed. T (On/Off): This button can both activate and turn off the system.

SET − (Set/Coast): Press to set the speed or make the vehicle decelerate. [ (Cancel): Press to cancel cruise control without erasing the set speed from memory. { WARNING: 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 I button. 2. Get up to the desired speed. 3. Press the SET− button located on the steering wheel and release it. 4. Take your foot off the accelerator. 4-7 Resuming a Set Speed If the cruise control is set at a desired speed and then the brakes are applied, this shuts off the cruise control. But it does not need to be reset. Once the vehicle speed reaches about 25 mph (40 km/h) or more, press the +RES button on the steering wheel. The vehicle returns to the previously set speed and stays there. Increasing Speed While Using Cruise Control To increase the cruise speed while using cruise control: • Press and hold the +RES button on the steering wheel until the desired speed is reached, then release it. • To increase vehicle speed in small increments, press the +RES button. Each time this is done, the vehicle goes about 1 mph (1.6 km/h) faster. Reducing Speed While Using Cruise Control To reduce the vehicle speed while using cruise control: • Press and hold the SET– button on the steering wheel until the desired lower speed is reached, 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 goes about 1 mph (1.6 km/h) slower. Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase the vehicle speed. When you take your foot off the pedal, the vehicle will slow down to the previous set cruise speed. 4-8 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 the vehicle’s speed. When going downhill, you might have to brake or shift to a lower gear to keep the vehicle’s speed down. When the brakes are applied the cruise control turns off. Ending Cruise Control There are three ways to end cruise control: • Step lightly on the brake pedal. • Press the [ button on the steering wheel. • Press the I button on the steering wheel. Erasing Speed Memory The cruise control set speed memory is erased when the cruise control or the ignition is turned off. Exterior Lamps The exterior lamps control is located on the instrument panel to the left of the steering wheel. It controls the following systems: • Headlamps • Taillamps • Parking Lamps • License Plate Lamps • Instrument Panel Lights 4-9 2 (Headlamps): Turns on the headlamps together with the following lamps listed below. • Parking Lamps • Instrument Panel Lights • Taillamps • License Plate Lamps If the headlamps are turned on while the vehicle is on, the headlamps turn off automatically 10 minutes after the ignition is turned off. If the headlamps are turned on while the vehicle is off, the headlamps will continue to stay on. To prevent the battery from being drained, turn the control to the 9 position. A warning chime sounds if the driver door is opened while the ignition switch is off and the headlamps are on. To change the headlamps from low beam to high beam, push the turn signal/multifunction lever toward the instrument panel. The exterior lamps control has four positions: O (Off): Brieﬂy turn the control to this position to turn the automatic headlamps and daytime running lamps (DRL) off or back on. For vehicles ﬁrst sold in Canada, the off position only works for vehicles that are shifted into the P (Park) position. AUTO (Automatic): Turns on the headlamps automatically at normal brightness, together with the following: • Parking Lamps • Instrument Panel Lights • Taillamps • License Plate Lamps ; (Parking Lamps): Turns on the parking lamps together with the following: • Instrument Panel Lights • Taillamps • License Plate Lamps 4-10 Headlamps on Reminder If a door is open, a reminder chime sounds when the headlamps or parking lamps are manually turned on and the key is out of the ignition. To turn off the chime, turn the headlamp switch to off or auto and then back on, or close and re-open the door. In the auto mode, the headlamps turn off once the ignition is in LOCK/OFF or may remain on until the headlamp delay ends, if enabled in the Driver Information Center (DIC). See “Exit Lighting” under DIC Vehicle Customization on page 4-52. Daytime Running Lamps (DRL) Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. Fully functional daytime running lamps are required on all vehicles ﬁrst sold in Canada. The DRL system comes on in daylight when the following conditions are met: • The ignition is on. • The exterior lamps control is in the AUTO position. • The shift lever is not in P (Park). • The light sensor determines it is daytime. When the DRL are on, the taillamps, sidemarker, instrument panel and other lamps will not be on. The automatic headlamp system automatically switches from DRL to the headlamps depending on the darkness of the surroundings. To turn off the DRL, turn the exterior lamp control to the off position and then release it. For vehicles ﬁrst sold in Canada, the transmission must be in the P (Park) position, before the DRL can be turned off. Automatic Headlamp System When it is dark enough outside and the headlamp switch is in AUTO, the automatic headlamp system turns on the headlamps, along with the taillamps, sidemarker, parking lamps, roof marker lamps, and the instrument panel lights. The radio lights will also be dim. To turn off the automatic headlamp system, turn the exterior lamps switch to the off position and then release. For vehicles ﬁrst sold in Canada, the transmission must be in the P (Park) position, before the automatic headlamp system can be turned off. The vehicle has a light sensor located on the top of the instrument panel. Do not cover the sensor or the system will come on whenever the ignition is on. The system may also turn on the headlamps when driving through a parking garage or tunnel. 4-11 Dome Lamps The dome lamps come on when any door is opened. They turn off after all the doors are closed. The dome lamps can also be turned on by turning the instrument panel brightness knob, located on the instrument panel to the left of the steering column, clockwise to the farthest position. In this position, the dome lamps remain on whether a door is opened or closed. 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 is only affected when the light sensor sees a change in lighting lasting longer than the delay. If the vehicle is started in a dark garage, the automatic headlamp system comes on immediately. Once the vehicle leaves the garage, it takes approximately 30 seconds for the automatic headlamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position. See Instrument Panel Brightness on page 4-12. Instrument Panel Brightness The knob for this feature is located next to the exterior lamps control. D (Instrument Panel Lights): Push the knob to extend and then turn clockwise or counterclockwise to brighten or dim the instrument panel lights and the radio display. This only works if the headlamps or parking lamps are on. To turn on the dome lamps, with the vehicle doors closed, turn the knob all the way clockwise. 4-12 Dome Lamp Override The dome lamp override button is located next to the exterior lamps control. The dome lamp override sets the dome lamps to remain off or come on automatically when a door is opened. E (Dome Lamp Override): Press the button in and the dome lamps remain off when a door is opened. Press the button again to return it to the extended position so that the dome lamps come on when a door is opened. Entry/Exit Lighting The vehicle has an illuminated entry/exit feature. The dome lamps come on if the dome override button is in the out position, when a door is opened or the key is removed from the ignition. Reading Lamps For vehicles with reading lamps, press the button located next to each lamp to turn it on or off. The vehicle may also have reading lamps in other locations. The lamps cannot be adjusted. 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. 4-13 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 4-44. Battery Run-Down Protection This feature shuts off the dome lamps if they are left on for more than 10 minutes when the ignition is in LOCK/OFF. This helps to prevent the battery from running down. 4-14 Accessory Power Outlet(s) The accessory power outlets can be used to connect auxiliary electrical equipment, such as a cellular phone. The vehicle may have two accessory power outlets located on the instrument panel. To use the accessory power outlet lift the cover. The spring cap cover closes by itself when the outlet is empty. Certain power accessory plugs may not be compatible to the accessory power outlet and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer/retailer for additional information on the accessory power plugs. 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. When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment. Notice: damage not covered by the vehicle 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. Improper use of the power outlet can cause If papers, pins, or other ﬂammable items Ashtray(s) and Cigarette Lighter For vehicles with an ashtray it is located in the center console or on the instrument panel. Pull up on the ashtray door to open it if it is in the console or pull the door open it if it is on the instrument panel.

If the driver safety belt is already buckled, neither the chime nor the light comes on. 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. 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. 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 2-60. 4-23 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. { WARNING: 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. For vehicles with a remote start, the airbag readiness light will stay on until the driver places the ignition switch to the ON/RUN position. 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 4-44 for more information. 4-24 Airbag Off Light When the right front passenger airbag is manually turned off using the airbag on-off switch on the instrument panel, if equipped, the indicator light OFF or the off symbol will come on and stay on as a reminder that the airbag has been turned off. This light will go off when the airbag has been turned on. See Airbag Off Switch on page 2-69 for more information, including important safety information. United States Canada { WARNING: { WARNING: If the right front passenger’s airbag is turned off for a person who is not in a risk group identiﬁed by the national government, that person will not have the extra protection of an airbag. In a crash, the airbag will not be able to inﬂate and help protect the person sitting there. Do not turn off the passenger’s airbag unless the person sitting there is in a risk group identiﬁed by the national government. See Airbag Off Switch on page 2-69 for more on this, including important safety information. If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. For example, the right front passenger airbag could inﬂate even though the airbag on-off switch is turned off. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light on page 4-23 for more information, including important safety information. If the word ON or the on symbol is lit, it means that the right front passenger frontal airbag is enabled (may inﬂate). See Airbag Off Switch on page 2-69 for more information, including important safety information. 4-25 Passenger Airbag Status Indicator If the vehicle has a passenger sensing system, the instrument panel will have a passenger airbag status indicator. See Passenger Sensing System on page 2-72 for important safety information. The instrument panel has a passenger airbag status indicator. United States Canada When the vehicle is started, the passenger airbag status indicator will light ON and OFF, or the symbol for on and off, for several seconds as a system check. Then, after several more seconds, the status indicator will light either ON or OFF, or either the on or off symbol to let you know the status of the right front passenger frontal airbag. 4-26 If the word ON or the on symbol is lit on the passenger airbag status indicator, it means that the right front passenger frontal airbag is enabled (may inﬂate). If the word OFF or the off symbol is lit on the airbag status indicator, it means that the passenger sensing system has turned off the right front passenger frontal airbag. 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. { WARNING: If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light on page 4-23 for more information, including important safety information. Charging System Light Voltmeter Gage This light comes on brieﬂy when the ignition key is turned to START, but the engine is not running, as a check to show it is working. When the engine is not running, but the ignition is on, this gage shows the battery’s state of charge in DC volts. If it does not, have the vehicle serviced by your dealer/retailer. The light should go out once the engine starts. If it stays on, or comes on while driving, there could be a problem with the charging system. A charging system message in the Driver Information Center (DIC) can also appear. See DIC Warnings and Messages on page 4-44 for more information. This light could indicate that there are problems with a generator drive belt, or that there is an electrical problem. Have it checked right away. If the vehicle must be driven a short distance with the light on, turn off accessories, such as the radio and air conditioner. 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. 4-27 When the ignition is on, the brake system warning light also comes on when the parking brake is set. See Parking Brake on page 3-35 for more information. The light stays on if the parking brake does not fully release. If it stays on after the parking brake is fully released, it means the vehicle has a brake problem. If the light comes on while driving, pull off the road and stop carefully. The pedal might be harder to push, or the pedal might go closer to the ﬂoor. It could take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 5-22. { WARNING: The brake system might not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to a crash. If the light is still on after the vehicle has been pulled off the road and carefully stopped, have the vehicle towed for service. The vehicle can be only driven for a short time with the reading in either warning zone. If it must be driven, 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. Brake System Warning Light The vehicle’s hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop the vehicle. For good braking, both need to work. If the warning light comes on, there could be a brake problem. Have the brake system inspected right away. United States Canada This light should come on brieﬂy when ignition key is turned to ON/RUN. If it does not come on, have it ﬁxed so it will be ready to warn if there is a problem. 4-28 Antilock Brake System (ABS) Warning Light For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 4-44 for all brake related DIC messages. For vehicles with the Antilock Brake System (ABS), this light comes on brieﬂy when the engine is started. StabiliTrak® Indicator Light For vehicles with the StabiliTrak® system, this light comes on or ﬂashes, according to the description table for the StabiliTrak system. 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 4-28. For more information, see StabiliTrak® System on page 5-5. Three chimes sound if the light turns on and one chime if the light turns off. If this light remains on steady, the vehicle needs to be taken in for service. 4-29 Engine Coolant Temperature Gage Tire Pressure Light For vehicles with a tire pressure monitoring system, this light comes on brieﬂy when the engine is started. It provides information about tire pressures and the Tire Pressure Monitoring System. United States Canada This gage shows the engine coolant temperature. It also provides an indicator of how hard the vehicle is working. During a majority of the operation, the gage will read 100°C (210°F) or less. If the vehicle is pulling a load or going up hills, it is normal for the temperature to ﬂuctuate and approach the 122°C (250°F) mark. If the gage reaches the 125°C (260°F) mark, it indicates that the cooling system is working beyond its capacity. See Engine Overheating on page 6-33. 4-30 When the Light is On Steady This indicates that one or more of the tires are signiﬁcantly underinﬂated. A tire pressure message in the Driver Information Center (DIC), can accompany the light. See Driver Information Center (DIC) on page 4-37 for more information. Stop and check the tires as soon as it is safe to do so. If underinﬂated, inﬂate to the proper pressure. See Inﬂation - Tire Pressure on page 6-63 for more information. When the Light Flashes First and Then is On Steady This indicates that there may 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 Operation on page 6-66 for more information. 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. 4-31 If the vehicle is continually driven with this 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: 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 6-3. 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: • Reduce vehicle speed. • Avoid hard accelerations. • 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. 4-32 An emission system malfunction might be corrected by doing the following: • Make sure the fuel cap is fully installed. See Filling the Tank on page 6-10. 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. • 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 6-6. 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. 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. 4-33 A reading in the low pressure zone may be caused by a dangerously low oil level or other problem causing low oil pressure. Check your oil as soon as possible. { WARNING: 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. Oil Pressure Gage United States Canada The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals). Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range. 4-34 Oil Pressure Light { WARNING: 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. 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. Security Light For information regarding this light and the vehicle’s security system, see PASS-Key® III+ Electronic Immobilizer Operation on page 3-20. 4-35 Cruise Control Light Tow/Haul Mode Light The cruise control light comes on whenever the cruise control is set. This light comes on when the Tow/Haul mode has been activated. The light goes out when the cruise control is turned off. See Cruise Control on page 4-6 for more information. Highbeam On Light For more information, see Tow/Haul Mode on page 3-33. Fuel Gage This light comes on when the high-beam headlamps are in use. See Headlamp High/Low-Beam Changer on page 4-5 for more information. United States Canada The fuel gage, when the ignition is on, indicates how much fuel is left in the vehicle’s fuel tank. 4-36 An arrow on the fuel gage indicates the side of the vehicle the fuel door is on. The gage ﬁrst indicates empty before the vehicle is out of fuel, and the fuel tank should be refueled soon. Listed are four situations customers might experience with the fuel gage. None of these indicate a problem with the fuel gage: • At the gas station, the fuel pump shuts off before the gage reads full. • It takes a little more or less fuel to ﬁll up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to ﬁll the tank. • The gage moves a little while turning a corner or speeding up. • The gage does not go back to empty when the ignition is turned off. If the vehicle has the DURAMAX Diesel engine, see the DURAMAX Diesel manual for more information. Driver Information Center (DIC) Your vehicle has a Driver Information Center (DIC). All messages will appear in the DIC display located at the bottom of the instrument panel cluster. The DIC buttons are located on the instrument panel, next to the instrument panel cluster. The DIC comes on when the ignition is on. After a short delay, the DIC will display the information that was last displayed before the engine was turned off. The DIC displays trip, fuel, and vehicle system information, and warning messages if a system problem is detected. If your vehicle has these features, the DIC also displays the compass direction and the outside air temperature when viewing the trip and fuel information. The compass direction appears on the top right corner of the DIC display. The outside air temperature automatically appears in the bottom right corner of the DIC display. If there is a problem with the system that controls the temperature display, the numbers will be replaced with dashes. If this occurs, have the vehicle serviced by your dealer/retailer. The DIC also allows some features to be customized. See DIC Vehicle Customization on page 4-52 for more information. 4-37 DIC Operation and Displays The DIC has different displays which can be accessed by pressing the DIC buttons located on the instrument panel, next to the instrument panel cluster. DIC Buttons The buttons are the trip/fuel, vehicle information, customization, and set/reset buttons. The button functions are detailed in the following pages. 3 (Trip/Fuel): Press this button to display the odometer, trip odometers, fuel range, average economy, fuel used, timer, average speed, and digital tachometer. 4-38 T (Vehicle Information): Press this button to display the oil life, units, tire pressure readings for vehicles with the Tire Pressure Monitor System (TPMS), engine hours, Tire Pressure Monitor System (TPMS) programming for vehicles with the TPMS and without a Remote Keyless Entry (RKE) transmitter, compass zone and compass calibration on vehicles with this feature, and RKE transmitter programming. U (Customization): Press this button to customize the feature settings on your vehicle. See DIC Vehicle Customization on page 4-52 for more information. V (Set/Reset): Press this button to set or reset certain functions and to turn off or acknowledge messages on the DIC. Trip/Fuel Menu Items 3 (Trip/Fuel): Press this button to scroll through the following menu items: Odometer Press the trip/fuel button until XX km (mi) displays. This display shows the distance the vehicle has been driven in either kilometers (km) or miles (mi). Trip Odometers Press the trip/fuel button until A or B displays. This display shows the current distance traveled in either kilometers (km) or miles (mi) since the last reset for each trip odometer. Both trip odometers can be used at the same time. Each trip odometer can be reset to zero separately by pressing the set/reset button while the desired trip odometer is displayed. The trip odometer has a feature called the retro-active reset. This can be used to set the trip odometer to the number of miles (kilometers) driven since the ignition was last turned on. This can be used if the trip odometer is not reset at the beginning of the trip. To use the retro-active reset feature, press and hold the set/reset button for at least four seconds. The trip odometer will display the number of kilometers (km) or miles (mi) driven since the ignition was last turned on and the vehicle was moving. Once the vehicle begins moving, the trip odometer will accumulate mileage. For example, if the vehicle was driven 8 km (5 miles) before it is started again, and then the retro-active reset feature is activated, the display will show 8 km (5 miles). As the vehicle begins moving, the display will then increase to 8.1 km (5.1 miles), 8.2 km (5.2 miles), etc. If the retro-active reset feature is activated after the vehicle is started, but before it begins moving, the display will show the number of kilometers (km) or miles (mi) that were driven during the last ignition cycle. Fuel Range Press the trip/fuel button until FUEL RANGE displays. This display shows the approximate number of remaining kilometers (km) or miles (mi) the vehicle can be driven without refueling. The display will show LOW if the fuel level is low. The fuel range estimate is based on an average of the vehicle’s fuel economy over recent driving history and the amount of fuel remaining in the fuel tank. This estimate will change if driving conditions change. For example, if driving in traffic and making frequent stops, this display may read one number, but if the vehicle is driven on a freeway, the number may change even though the same amount of fuel is in the fuel tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving. If your vehicle is low on fuel, the FUEL LEVEL LOW message will be displayed. See “FUEL LEVEL LOW” under DIC Warnings and Messages on page 4-44 for more information. 4-39 Average Economy Press the trip/fuel button until AVG ECONOMY displays. This display shows the approximate average liters per 100 kilometers (L/100 km) or miles per gallon (mpg).

To start the timer, press the set/reset button while TIMER is displayed. The display will show the amount of time that has passed since the timer was last reset, not including time the ignition is off. Time will continue to be counted as long as the ignition is on, even if another display is being shown on the DIC. 4-40 The timer will record up to 99 hours, 59 minutes and 59 seconds (99:59:59) after which the display will return to zero. To stop the timer, press the set/reset button brieﬂy while TIMER is displayed. To reset the timer to zero, press and hold the set/reset button while TIMER is displayed. Average Speed Press the trip/fuel button until AVERAGE SPEED displays. This display shows the average speed of the vehicle in kilometers per hour (km/h) or miles per hour (mph). This average is calculated based on the various vehicle speeds recorded since the last reset of this value. To reset the value, press and hold the set/reset button. The display will return to zero. Digital Tachometer Press the trip/fuel button until Tachometer ##00 RPM displays. This display shows the engine speed in revolutions per minute (RPM). Blank Display This display shows no information. Vehicle Information Menu Items T (Vehicle Information): Press this button to scroll through the following menu items: Oil Life Press the vehicle information button until OIL LIFE REMAINING displays. This display shows an estimate of the oil’s remaining useful life. If you see 99% OIL LIFE REMAINING on the display, that means 99% of the current oil life remains. The engine oil life system will alert you to change the oil on a schedule consistent with your driving conditions. When the remaining oil life is low, the CHANGE ENGINE OIL SOON message will appear on the display. See “CHANGE ENGINE OIL SOON” under DIC Warnings and Messages on page 4-44. You should change the oil as soon as possible. See Engine Oil on page 6-15. In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Scheduled Maintenance on page 7-3 for more information. Remember, you must reset the OIL LIFE yourself after each oil change. It will not reset itself. Also, be careful not to reset the OIL LIFE accidentally at any time other than when the oil has just been changed. It cannot be reset accurately until the next oil change. To reset the engine oil life system, see Engine Oil Life System on page 6-18. Units Press the vehicle information button until UNITS displays. This display allows you to select between English or Metric units of measurement. Once in this display, press the set/reset button to select between ENGLISH or METRIC units. Tire Pressure If your vehicle has the Tire Pressure Monitor System (TPMS), the pressure for each tire can be viewed in the DIC. The tire pressure will be shown in either kilopascals (kPa) or pounds per square inch (psi). Press the vehicle information button until the DIC displays FRONT TIRES PSI (kPa) LEFT ## RIGHT ##. Press the vehicle information button again until the DIC displays REAR TIRES PSI (kPa) LEFT ## RIGHT ##. If a low tire pressure condition is detected by the system while driving, a message advising you to check the pressure in a speciﬁc tire will appear in the display. See Inﬂation - Tire Pressure on page 6-63 and DIC Warnings and Messages on page 4-44 for more information. If the tire pressure display shows dashes instead of a value, there may be a problem with your vehicle. If this consistently occurs, see your dealer/retailer for service. 4-41 Engine Hours Press the vehicle information button until ENGINE HOURS displays. This display shows the total number of hours the engine has run. Relearn Tire Positions Your vehicle may have this display. To access this display, the vehicle must be in P (Park). If your vehicle has the Tire Pressure Monitor System (TPMS), after rotating the tires or after replacing a tire or sensor, the system must re-learn the tire positions. To re-learn the tire positions, see Tire Pressure Monitor System on page 6-65. See Tire Inspection and Rotation on page 6-69 and DIC Warnings and Messages on page 4-44 for more information. Change Compass Zone Your vehicle may have this feature. To change the compass zone through the DIC, see DIC Compass on page 4-43. Calibrate Compass Your vehicle may have this feature. The compass can be manually calibrated. To calibrate the compass through the DIC, see DIC Compass on page 4-43. Relearn Remote Key To access this display, the vehicle must be in P (Park). This display allows you to match Remote Keyless Entry (RKE) transmitters to your vehicle. This procedure will erase all previously learned transmitters. Therefore, they must be relearned as additional transmitters. To match an RKE transmitter to your vehicle: 1. Press the vehicle information button until PRESS V TO RELEARN REMOTE KEY displays. 2. Press the set/reset button until REMOTE KEY LEARNING ACTIVE is displayed. 3. Press and hold the lock and unlock buttons on the ﬁrst transmitter at the same time for about 15 seconds.

To exit the programming mode, you must cycle the key to LOCK/OFF. Blank Display This display shows no information. 4-42 DIC Compass Your vehicle may have a compass in the Driver Information Center (DIC). Compass Zone 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 P (Park). Press the vehicle information button until PRESS V TO CHANGE 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/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. 4-43 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. 4-44 2. Press the vehicle information button until PRESS V TO CALIBRATE COMPASS displays. 3. Press the set/reset button to start the compass calibration. 4. The DIC will display CALIBRATING: 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 COMPLETE for a few seconds when the calibration is complete. The DIC display will then return to PRESS V TO CALIBRATE COMPASS. DIC Warnings and Messages Messages are displayed on the DIC to notify the driver that the status of the vehicle has changed and that some action may be needed by the driver to correct the condition. Multiple messages may appear one after another. Some messages may not require immediate action, but you can press any of the DIC buttons on the instrument panel to acknowledge that you received the messages and to clear them from the display. Some messages cannot be cleared from the DIC display because they are more urgent. These messages require action before they can be cleared. You should take any messages that appear on the display seriously and remember that clearing the messages will only make the messages disappear, not correct the problem. The following are the possible messages that can be displayed and some information about them. If your vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information. AUTOMATIC LIGHT CONTROL OFF This message displays when the automatic headlamps are turned off. See Exterior Lamps on page 4-9 for more information.
