See Windshield Washer on page 3-11. 3-8 Turn and Lane-Change Signals To signal a turn, move the lever on the left side of the steering wheel all the way up or down. The lever returns automatically when the turn is complete. An arrow on the instrument panel cluster will ﬂash in the direction of the turn or lane change. You may also have an arrow in the outside mirror that ﬂashes when the turn signal is used. See Outside Power Mirrors on page 2-37 for more information. Raise or lower the lever until the arrow starts to ﬂash to signal a lane change. Hold it there until the lane change is complete. If you momentarily press and release the lever, the turn signal will ﬂash three times. If the arrows ﬂash very fast as you signal a turn or a lane change, a signal bulb may be burned out and other drivers will not see your turn signal. If a bulb is burned out, replace it to help avoid an accident. If the arrows do not go on at all when you signal a turn, check the fuse. See Fuses and Circuit Breakers on page 5-105. (cid:129) Turn Signal On Chime If your turn signal is left on for more than 0.8 miles (1.3 km), a chime will sound at each ﬂash of the turn signal. To turn off the chime, move the turn signal lever to the off position. Headlamp High/Low-Beam Changer To change the headlamps from low beam to high beam, push the turn signal lever away from you. To change from high beam to low beam, pull the turn signal lever toward you. While the high beams are on, this light located on the instrument panel cluster will also be on. Flash-to-Pass This feature lets you use the high-beam headlamps to signal the driver in front of you that you want to pass. It works even if your headlamps are off. Pull the turn signal lever toward you brieﬂy to ﬂash-to-pass. If the headlamps are off or on low beam, the high-beam headlamps will turn on. They will stay on as long as you hold the lever toward you and the high-beam indicator on the instrument panel cluster will come on. Windshield Wipers You control the windshield wipers by turning the band with the wiper symbol on it. 8(Mist): Turn the band to mist for a single wiping cycle. Hold it there until the wipers start. Then let go. The wipers stop after one wipe. For more wipe cycles, hold the band longer on mist. 6 (Delay): Turn the band to choose the delay time between wipe cycles. The wiper speed can be set for a long or short delay between wipes. The closer the band is set to the top of the lever, the shorter the delay. 6 (Low Speed): Turn the band away from you to the ﬁrst solid band past the delay settings for steady wiping at low speed. 3-9 1 (High Speed): For high-speed wiping, turn the band further, to the second solid band past the delay settings. 9(Off): To stop the wipers, move the band to off. Clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, carefully loosen or thaw them. If the blades become worn or damaged, replace with new blades or blade inserts. Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools. Clear away snow or ice to prevent an overload. Your vehicle has wiper-activated headlamps. After the windshield wipers have completed eight wipe cycles within four minutes, the headlamps automatically turn on. See Wiper Activated Headlamps on page 3-15 for more information. Rainsense™ II Wipers If your vehicle has this feature, the moisture sensor is mounted on the interior of the windshield beside the rearview mirror and is used to automatically operate the wipers. This system operates by monitoring the amount of moisture build-up on the windshield. Wipes occur as needed to clear the windshield depending on the driving conditions and the sensitivity setting. In light rain or snow, fewer wipes will occur. In heavy rain or snow, wipes will 3-10 occur more frequently. The system operates in the delay mode. If the system is left on for long periods of time, occasional wipes may occur without any moisture on the windshield. This is normal and indicates that the Rainsense™ system is active. The Rainsense™ system is activated by turning the wiper control band to one of the ﬁve sensitivity levels within the delay area. The position closest to off is the lowest sensitivity setting, level one. This allows more rain or snow to collect on the windshield between wipes. Turning the wiper band away from you to higher sensitivity levels increases the sensitivity of the system and frequency of wipes. The highest sensitivity setting, level ﬁve is closest to low. A single wipe will occur each time you turn the wiper stalk to a higher sensitivity level to indicate that the sensitivity level has been increased. Notice: Going through an automatic car wash with the wipers on can damage them. Turn the wipers off when going through an automatic car wash. The MIST and wash cycles operate as normal and are not affected by the Rainsense™ function. The system can be overridden at any time by manually changing the wiper control to low or high speed. Notice: Do not place stickers or other items on the exterior glass surface directly in front of the rain sensor. Doing this could cause the rain sensor to malfunction. Windshield Washer {CAUTION: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer ﬂuid can form ice on the windshield, blocking your vision. J (Washer Fluid): Press and release this paddle, located at the top of the turn signal/multifunction lever, to spray washer ﬂuid on the windshield. The wipers will clear the windshield and either stop or return to your preset speed. For more washer cycles, press and hold the paddle. _ (Heated Washer Fluid): The heated windshield washer ﬂuid system, if your vehicle has this feature, may be used to help clear ice, snow, tree sap, or bugs from your windshield. Sliding the switch on the turn signal/multifunction lever to this position and then releasing it will activate the heated windshield washer ﬂuid system. This activation will initiate four heated wash/wipe cycles. The ﬁrst heated wash/wipe cycle may take up to 40 seconds to occur, depending on outside temperature. After the ﬁrst wash/wipe cycle, it may take up to 20 seconds for each of the remaining cycles. The heated windshield washer ﬂuid system may be turned off at any time by sliding the switch on the turn signal/multifunction lever to this position again. When the heated windshield washer ﬂuid system is activated under certain outside temperature conditions, steam may ﬂow out of the washer nozzles for a short period of time before washer ﬂuid is sprayed. This is a normal condition. WASHER FLUID LOW ADD FLUID will be displayed on the Driver Information Center (DIC) when the washer ﬂuid is low. See DIC Warnings and Messages on page 3-56. 3-11 Cruise Control With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). {CAUTION: Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use your cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. If your vehicle has the Traction Control System (TCS) and the cruise control is on, TCS will begin to limit wheel spin and the cruise control automatically turns off. See Traction Control System (TCS) on page 4-5. When road conditions allow you to safely use it again, the cruise control can be turned back on. 3-12 The cruise control buttons are located on outboard side of the steering wheel. T (On/Off): Press this button to turn cruise control on and off. The indicator is lit when cruise control is on. + RES (Resume/Accelerate): Press this button to make the vehicle accelerate or resume to a previously set speed. SET–: Press this button to set the speed or make the vehicle decelerate. [ (Cancel): Press this button to cancel cruise control. 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. See Instrument Panel Cluster on page 3-33. {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:129) 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. 3-13 (cid:129) Ending Cruise Control There are three ways to end cruise control: (cid:129) Step lightly on the brake pedal. (cid:129) Press the [ button on the steering wheel. (cid:129) 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. Exterior Lamps The exterior lamps control is located on the instrument panel to the left of the steering wheel. Reducing Speed While Using Cruise Control To reduce your speed while using cruise control: (cid:129) 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. 3-14 (cid:129) It controls the following systems: (cid:129) Headlamps Taillamps (cid:129) Parking Lamps License Plate Lamps Instrument Panel Lights Fog Lamps (If Equipped) 2(Headlamps): Turn the control to this position to turn on the headlamps together with the following lamps listed below. A warning chime sounds if the driver’s door is opened while the ignition switch is off and the headlamps are on. (cid:129) Parking Lamps License Plate Lamps Instrument Panel Lights The exterior lamps control has four positions: O (Off): Turn the control to this position to turn off the exterior lamps. AUTO (Automatic): Turn the control to this position to automatically turn on the headlamps at normal brightness, together with the following: (cid:129) Parking Lamps Instrument Panel Lights ;(Parking Lamps): Turn the control to this position to turn on the parking lamps together with the following: -(Fog Lamps): Push the exterior lamps control in to turn on the fog lamps. See Fog Lamps on page 3-17. Wiper Activated Headlamps This feature activates the headlamps and parking lamps after the windshield wipers are turned on and have completed eight wipe cycles within four minutes. When the ignition is turned to LOCK/OFF, the wiper-activated headlamps immediately turn off. The wiper-activated headlamps also turn off if the windshield wipers are turned off. Taillamps License Plate Lamps Instrument Panel Lights 3-15 (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) Headlamps on Reminder If you leave the exterior lamp buttons for the headlamps or parking lamps on, remove the key from the ignition and open the driver’s door, you will hear a continuous warning chime. The chime will turn off when the lamps are turned off. Daytime Running Lamps (DRL) Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. Fully functional daytime running lamps are required on all vehicles ﬁrst sold in Canada. A light sensor on top of the instrument panel monitors the exterior light level for the operation of DRL, so be sure it is not covered. The DRL system makes the low-beam headlamps turn on at reduced brightness in daylight when the following conditions are met: The ignition is on. The exterior lamp button for the headlamps is off. The automatic transmission is not in PARK (P). When the DRL are on, only the low-beam headlamps will be on. The parking lamps, taillamps, sidemarker and other lamps will not be on. When it is dark enough outside, the low-beam headlamps will come on. The other lamps that turn on with the headlamps will also turn on. When it is bright enough outside, the regular lamps will go off, and the low-beam headlamps change to the reduced brightness of DRL. To turn off all exterior lighting at night when the vehicle is parked, turn the exterior lamp control to the off position. The exterior lamps will turn back on automatically when the transmission is moved out of PARK (P). See Exterior Lamps on page 3-14 for more information. As with any vehicle, the regular headlamp system should be turned on when needed. 3-16 (cid:129) (cid:129) (cid:129) Fog Lamps - (Fog Lamps): If your vehicle has fog lamps, the button is located on the exterior lamps control. The exterior lamps control is located on the instrument panel to the left of the steering column. The ignition must be in the ON/RUN position and the parking lamps must be on for the fog lamps to illuminate. To turn the fog lamps on, press the exterior lamps button. A light comes on in the instrument panel cluster to show that the fog lamps are on. See Instrument Panel Cluster on page 3-33. Press the exterior lamps button again to turn the fog lamps off. The fog lamps will go off while you change to high-beam headlamps. Some localities have laws that require the headlamps to be on along with the fog lamps. Cornering Lamps If your vehicle has this feature, the cornering lamps come on when: the headlamps or parking lamps are on, the vehicle is not in PARK (P), and you signal a turn with the turn signal/multifunction lever. They provide more light for cornering. Exterior Lighting Battery Saver If the exterior lamp button has been left on, the exterior lamps will turn off about 10 minutes after the ignition is turned to LOCK/OFF and a door has been opened. This protects against draining the battery if the headlamps or parking lamps are accidentally left on. If you need to leave the lamps on for more than 10 minutes, use the exterior lamp control to turn the lamps back on after the ignition is turned to LOCK/OFF and any door is opened. Instrument Panel Brightness D(Instrument Panel Brightness): This feature controls the brightness of the instrument panel lights. The knob for this control is located next to the exterior lamps control. Push the knob in and release when it pops out. Turn the knob clockwise to increase the brightness of the instrument panel lights and counter clockwise to decrease the brightness. Turning the knob completely clockwise to the detent will turn on the courtesy lamps. Courtesy Lamps When any door is opened, several lamps turn on making it easier for you to enter and exit the vehicle. Turn the instrument panel brightness control completely clockwise to manually turn on these lamps. 3-17 Entry Lighting If it is dark enough outside when you press the unlock button on the remote keyless entry transmitter, the interior courtesy lamps will turn on and stay on for about 40 seconds. The lamps can be turned off immediately by pressing the lock button on the remote keyless entry transmitter, turning the ignition key to RUN or activating the power door locks. Delayed Entry Lighting The interior lamps will turn on if you open the door when it is dark enough outside. When you close the door with the ignition off, the interior lamps will stay on for up to 25 seconds or until the ignition is turned to an on position. When the lamps turn off as a result of the 25 second timer or the ignition switch being turned on, the lighting will deactivate by way of the theater dimming effect. Locking the doors will override the delayed entry lighting feature and the lamps will turn off right away. 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 If it is dark enough outside when you remove the key from the ignition, the interior lamps will turn on and stay on for about 25 seconds. This will give you time to ﬁnd the door pull handle or lock switches. Once the key is inserted into the ignition, the exit lighting will be cancelled and the lighting will fade out. Perimeter Lighting If it is dark enough outside when the unlock button on the remote keyless entry transmitter is pressed, the DRL, parking lamps and back-up lamps will come on. This feature can be programmed on for various amounts of time in seconds for each transmitter. See DIC Vehicle Customization on page 3-66 for information on programming. Front Reading Lamps The front reading lamps, located on the headliner, are turned on or off by pressing one of the buttons located near each lamp. 3-18 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 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. 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, a Driver Information Center (DIC) message might be displayed, such as Battery Saver Active or Service Battery Charging System. 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. Inadvertent Power Battery Saver This feature is designed to protect your vehicle’s battery against drainage from the interior lamps, or garage door opener. When the ignition is turned off, the power to these features will automatically turn off after 10 minutes. Power will be restored for an additional 10 minutes if any door is opened, the trunk is opened or the courtesy lamp switch is turned on. 3-19 Your vehicle may have a small cap that must be pulled down to access the accessory power outlet. Cover the outlet with the protective cap when it is not being used. Notice: Leaving electrical equipment on for extended periods will drain the battery. Always turn off electrical equipment when not in use and do not plug in equipment that exceeds the maximum amperage rating. Certain electrical accessories may not be compatible to the accessory power outlets 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 outlets. 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. Battery Run-Down Protection This vehicle has a feature to help prevent the battery from being drained, if the interior courtesy lamps, reading/map lamps, visor vanity lamps or trunk lamp are accidentally left on. If any of these lamps are left on, they will automatically turn off after 10 minutes, if the ignition is off. The lamps will not come back on again until one of the following occurs: The ignition is turned on. The exterior lamps control is turned off, then on again. The headlamps will timeout after 10 minutes, if they are manually turned on before the ignition is off. Accessory Power Outlet(s) The accessory power outlets can be used to plug in electrical equipment such as a cellular telephone or CB radio. Your vehicle may have up to three power outlets depending on the type of front seat installed. If your vehicle has front bucket seats with a center console, there are two outlets inside the rear storage compartment. An extra power outlet can be found under the climate control system next to the ashtray. 3-20 (cid:129) (cid:129) If you put papers, pins, or other ﬂammable Improper use of the power outlet can cause When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment. 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. Ashtray(s) 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. For vehicles without the ﬂoor console, pull the tray located below the climate controls to reveal the ashtray. The ashtray can be removed by pulling on the ledge located at the top of the ashtray. The vehicles with a full ﬂoor console do not have an ashtray. There is a storage bin below the climate control system. For more information, see Front Storage Area on page 2-56. Climate Controls Climate Control System The heating, cooling, and ventilation for the vehicle can be controlled with this system. If your vehicle has the remote start feature and it is activated, the climate control system heats or cools the inside of the vehicle, with the settings used before the vehicle was turned off. The heated seats, if the vehicle has them, and the rear window defogger will be turned on by the climate control system when it is cold outside. The cooled seat setting is not activated during a remote start. Normal operation of the system will return after the key is turned to the ON/RUN position. See Remote Keyless Entry (RKE) System Operation on page 2-5 for more information. 3-21 Operation ( (Off): Turn the left knob to this position to turn the climate control system off. Outside air still enters the vehicle and is directed to the ﬂoor. The airﬂow direction and temperature can be adjusted, as indicated below. 9 (Fan): Turn the left knob clockwise or counterclockwise to increase or decrease the fan speed. The fan speed is temporarily reduced between the transition to a new mode. The fan will resume when the new mode is complete. If the airﬂow seems low when the fan speed is at the highest setting, the passenger compartment air ﬁlter may need to be replaced. For more information, see Passenger Compartment Air Filter on page 3-30 and Scheduled Maintenance on page 6-4. Temperature Control: Turn the center knob clockwise or counterclockwise to warm or cool the air coming through the outlets. Mode Control: Turn the right knob clockwise or counterclockwise to change the airﬂow direction. H (Vent): This mode directs outside air to the instrument panel outlets. ) (Bi-Level): This mode splits the air between the instrument panel outlets and the ﬂoor outlets. Slightly cooler air is directed to the instrument panel outlets and warmer air is directed to the ﬂoor outlets. 6 (Floor): This mode automatically uses outside air and directs most to the ﬂoor outlets. Some air is directed toward the side window outlets and to the windshield. If recirculation is selected while in this mode, it stays on for three minutes to reduce windshield fogging. h (Recirculation): Press this button to recirculate cabin air through the vehicle. An indicator light below the button comes on to show that this mode is activated. This mode can be used to prevent outside air and odors from entering the vehicle or to help cool the air inside the vehicle more quickly. This mode cannot be selected while in the defog or defrost modes. If you try to select the recirculation mode, the indicator light ﬂashes three times and turns off. 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. 3-22 # (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 comes on to show that this mode is activated. Air conditioning can be selected in any mode as long as the fan knob is not in the off position. 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. 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 a small amount of water may drip underneath the vehicle while idling or after turning off the engine. This is normal. 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 ﬂoor/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. The recirculation mode cannot be selected while in these modes. - (Floor/Defog): This mode directs half of the air to the windshield and the side window outlets and half to the ﬂoor outlets. The system runs the air conditioning compressor unless the outside temperature is near or below freezing. 0 (Defrost): This mode directs most of the air to the windshield and the side window outlets. The system runs the air conditioning compressor unless the outside temperature is near or below freezing. 3-23 Dual Automatic Climate Control System The heating, cooling, and ventilation for the vehicle can be controlled with this system. If your vehicle has the remote start feature and it is activated, the climate control system heats or cools the inside of the vehicle, with the settings used before the vehicle was turned off. The heated seats, if the vehicle has them, and the rear window defogger will be turned on by the climate control system when it is cold outside. The cooled seat setting is not activated during a remote start. Normal operation of the system will return after the key is turned to the ON/RUN position. See Remote Keyless Entry (RKE) System Operation on page 2-5 for more information. Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. < (Rear Window Defogger): Press this button to turn the rear window defogger on or off. An indicator light below the button comes on to show that the rear window defogger is activated. Be sure to clear as much snow from the rear window as possible. The rear window defogger will only work when the ignition is in ON/RUN. The rear window defogger stays on for about 20 minutes after the button is pressed if traveling at slow speeds. At higher vehicle speeds, the rear defogger may stay on continuously. If turned on again, the defogger only runs for about 10 minutes before turning off. The defogger can be turned off by pressing the button again, by turning the ignition to ACC/ACCESSORY or ON/RUN, or by turning off the engine. If your vehicle has heated outside rearview mirrors, the mirrors heat to help clear fog or frost from the surface of the mirror when the rear window defogger is on. See Outside Automatic Dimming Heated Mirror on page 2-38 for more information. 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. 3-24 Automatic Operation AUTO (Automatic Fan): When AUTO is selected on the fan control, the system automatically adjusts the fan speed. If the OnStar® system is activated when this position is selected, the fan speed will lower. AUTO (Automatic Mode) 1. Turn the fan control to AUTO. 2. Turn the mode control to AUTO. 3. Adjust the temperature to a comfortable setting between 68°F (21°C) and 78°F (26°C). Choosing the coldest or warmest temperature setting will not cause the system to heat or cool any faster. In cold weather, the system starts at reduced fan speeds to avoid blowing cold air into the vehicle until warmer air is available. The system will start out blowing air to the ﬂoor, but may change modes automatically as the vehicle warms up to maintain the chosen temperature setting. The length of time needed to warm the interior depends on the outside temperature. 4. Wait a few minutes for the system to automatically regulate. Then adjust the temperature as necessary to ﬁnd your comfort setting. Do not cover the solar sensor located in the center of the instrument panel, near the windshield. For more information on the solar sensor, see “Sensors” later in this section. After the vehicle is started, the display shows the interior temperature settings. When the ENG/MET (English/metric) button on the Driver Information Center (DIC) is pressed, the display shows readings in Fahrenheit or Celsius. Use the ENG/MET button to toggle between the readings. AUTO (Automatic Air Conditioning): If AUTO is selected on the fan or mode control, the system automatically controls the air conditioning compressor. The A/C compressor runs automatically even at cool outside temperatures in order to dehumidify the air. The A/C indicator light is lit when the system is operating automatically. Press the A/C button on the fan control to turn off the A/C. To clear windows better in defog or defrost modes, the A/C compressor runs automatically in damp cool conditions. h (Auto Recirculation): If AUTO is selected on either the fan or mode control, the system automatically controls the supply of fresh outside air or recirculates the interior air to cool the car faster. The indicator light on the recirculation button will light whenever the system switches to recirculation. You may force outside air by pressing the outside air button. The next time AUTO fan or mode is selected, it will reset back to AUTO operation. 3-25 Manual Operation 9 (Fan): Turn the left knob either to the left or right to adjust the fan speed. Turning this control completely counterclockwise turns on the automatic fan operation. If the airﬂow seems low when the fan speed is at the highest setting, the passenger compartment air ﬁlter may need to be replaced. For more information, see Passenger Compartment Air Filter on page 3-30 and Scheduled Maintenance on page 6-4. 9 (Off): Turn the left control to this position to turn the climate control system off. Outside air still enters the vehicle and is directed to the ﬂoor. The airﬂow direction and temperature can be adjusted, as indicated below. If the temperature is adjusted while the system is off, the display will light to show the current settings. Mode Control: Turn the right knob clockwise or counterclockwise to change the airﬂow direction. F (Vent): This mode directs outside air to the instrument panel outlets. * (Bi-Level): This mode splits the air between the instrument panel outlets and the ﬂoor outlets. In automatic operation, cooler air is directed to the upper outlets and warmer air to the ﬂoor outlets. 7 (Floor): This mode automatically uses outside air and directs most to the ﬂoor outlets. Some air is directed toward the side window outlets and to the windshield. If recirculation is selected while in this mode, it stays on for three minutes to reduce windshield fogging. The mode control can also be used to select the ﬂoor/defog mode. Information on defogging and defrosting can be found later in this section. # (Air Conditioning): Press the center of the left control knob to override the automatic system and turn the air conditioning system on or off. When this button is pressed, an indicator light below the button comes on to show that this mode is activated.

This is normal. 3-26 : (Outside Air): This mode lets outside air enter the vehicle. When the button is pressed, an indicator light turns on. Pressing the recirculation button cancels this mode. ? (Recirculation): Press this button to recirculate cabin air through the vehicle. An indicator light below the button comes on to show that this mode is activated. This mode can be used to prevent outside air and odors from entering the vehicle or to help cool the air inside the vehicle more quickly. This mode cannot be selected while in the defog or defrost modes. If you try to select the recirculation mode, the indicator light ﬂashes three times and turns off. 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. wx (Driver Temperature Controls): Press these buttons next to the fan control to manually increase or decrease the temperature inside the vehicle. wx (Passenger Temperature Controls): Press these buttons next to the mode control to manually increase or decrease the temperature for the front passenger. If the passenger climate control system is off, pressing one of these buttons turns it on. PASS (Passenger Climate Control): Press this button to turn the passenger climate control systems on or off. When the passenger climate control system is on, the passenger temperature setting is displayed. If the PASS button is pressed to turn the passenger temperature setting off, the driver temperature setting controls the temperature for the entire vehicle. 3-27 There is also an exterior temperature sensor located behind the front grille. This sensor reads the outside air temperature and helps maintain the temperature inside the vehicle. Any cover on the front of the vehicle could cause a false temperature reading to display. In order to prevent false temperature readings at startup, the displayed temperature will not change until the following occurs: (cid:129) Vehicle speed is above 10 mph (16 km/h) for ﬁve minutes. (cid:129) Vehicle speed is above 32 mph (51 km/h) for two and a half minutes. The climate control system uses the information from these sensors to maintain your comfort setting by adjusting the outlet temperature, fan speed, and the air delivery mode. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be used as needed to maintain cool outlet temperatures. Sensors The solar sensor, located in the defrost grille, in the middle of the instrument panel, monitors the solar radiation. Do not cover the solar sensor or the system will not work properly. There is also an interior temperature sensor located next to the steering wheel that measures the temperature of the air inside the vehicle. 3-28 Defogging and Defrosting Fog on the inside of windows is a result of high humidity (moisture) condensing on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to clear fog from your windshield, defog and defrost. W (Floor/Defog): Use this mode to clear the windows of fog or moisture and to warm the passengers. Turning the control to this mode directs about half of the air to the ﬂoor outlets and the remaining air is directed to the side window outlets and to the windshield. When this mode is selected, the system turns off recirculation and runs the air-conditioning compressor unless the outside temperature is at or below freezing. The recirculation mode cannot be selected while in the ﬂoor/defog mode. 0 (Defrost): Use this mode to remove fog or frost from the windshield more quickly. Turning the control to this mode directs most of the air to the windshield and the side window outlets. In this mode, the system automatically turns off recirculation and runs the air-conditioning compressor, unless the outside temperature is at or below freezing. Recirculation cannot be selected while in the defrost mode. Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. < (Rear Defogger): Press this button to turn the rear window defogger on or off. An indicator light below the button comes on to show that the rear window defogger is activated. Be sure to clear as much snow from the rear window as possible. The rear window defogger will only work when the ignition is in ON/RUN. The rear window defogger stays on for about 20 minutes after the button is pressed if you are traveling at slower vehicle speeds. At higher vehicle speeds the rear window defogger may stay on continuously. If turned on again, the defogger only runs for about 10 minutes before turning off. The defogger can be turned off by pressing the button again, by turning the ignition to ACC/ACCESSORY or ON/RUN, or by turning off the engine. The heated outside rearview mirrors will heat to help clear fog or frost from the surface of the mirror when the rear window defogger is on. See Outside Automatic Dimming Heated Mirror on page 2-38 for more information. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty. 3-29 Passenger Compartment Air Filter Outside air is routed through a passenger compartment air ﬁlter before entering the vehicle. This ﬁlter removes certain particles from the air, including pollen and dust particles. The ﬁlter should be replaced as part of routine scheduled maintenance. See Scheduled Maintenance on page 6-4 for when to replace the ﬁlter. Outlet Adjustment Use the levers, located in the middle of the front outlets, to change the direction of the airﬂow. Use the thumbwheel located between the outlets to turn them on and off. If your vehicle has rear seat outlets, adjust the direction of the airﬂow using the lever in the center of each outlet. Operation Tips (cid:129) Clear away any ice, snow, or leaves from the air inlets at the base of the windshield that could block the ﬂow of air into your vehicle. (cid:129) Use of non-GM approved hood deﬂectors can adversely affect the performance of the system. (cid:129) Keep the path under the front seats clear of objects to help circulate the air inside the vehicle better. The access panel for the passenger compartment air ﬁlter is located under the hood near the windshield, on the passenger’s side of the vehicle. 3-30 To access the passenger compartment air ﬁlter, do the following: 1. Press the tabs back and left to remove the cover. 2. Insert a tool behind the push pin located on the inboard side of the air ﬁlter compartment to carefully pry the pin out. 3. To remove the air ﬁlter, insert a tool between the air ﬁlter and the compartment wall on the outboard side of the vehicle. Then, push in to ﬂatten the pin holding the air ﬁlter in place. Gently remove the air ﬁlter and any loose debris that may be inside the air ﬁlter compartment. 4. Insert the new air ﬁlter by pushing until you hear a click. Reinstall the push pin and snap the cover into place. 3-31 Warning Lights, Gages, and Indicators This part describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them. Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to your warning lights and gages could also save you or others from injury. Warning lights come on when there may be or is a problem with one of your vehicle’s functions. As you will see in the details on the next few pages, some warning lights come on brieﬂy when you start the engine just to let you know they 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 your warning lights and gages. They are a big help. Your vehicle has a DIC that works along with the warning lights and gages. See Driver Information Center (DIC) on page 3-48. 3-32 Instrument Panel Cluster The instrument panel cluster is designed to let you know at a glance how your vehicle is running. You will know how fast you are going, how much fuel you have, and many other things you will need to drive safely and economically. Your vehicle has this cluster or one very similar to it. It includes indicator warning lights and gages that are explained on the following pages. Be sure to read about them. United States uplevel shown, Canada and base similar 3-33 Safety Belt Reminders Safety Belt Reminder Light When the engine is started, a chime will come on for several seconds to remind people to fasten their safety belts, unless the driver’s safety belt is already buckled. The safety belt light will also come on and stay on for several seconds, then it will ﬂash for several more. 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. Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your odometer shows how far your vehicle has been driven, in either miles or kilometers. Your vehicle has a tamper resistant odometer. You may wonder what happens if your vehicle needs a new odometer installed. If the new one can be set to the mileage total of the old odometer, then it must be. But if it cannot, then it is set at zero and a label must be put on the driver’s door to show the old mileage reading when the new odometer was installed. Trip Odometer A trip odometer can tell you how far you have driven since you last set it to zero. See Driver Information Center (DIC) on page 3-48 for information on resetting the trip odometer. Tachometer Your tachometer displays the engine speed in revolutions per minute (rpm). 3-34 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 1-67 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 1-58. 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. 3-35 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 overhead console has a passenger airbag status indicator. {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 3-56 for more information. 3-36 United States Canada When you start the vehicle, 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’s frontal airbag and seat-mounted side impact airbag. If the word ON or the on symbol is lit on the passenger airbag status indicator, it means that the right front passenger’s frontal airbag and seat-mounted side impact airbag are enabled (may inﬂate). {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 and seat-mounted side impact airbag (if equipped). 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 and seat-mounted side impact airbag (if equipped) 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 a rear seat, even if the airbag is or airbags are off. 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’s frontal airbag and seat-mounted side impact airbag. See Passenger Sensing System on page 1-67 for more on this, including important safety information. 3-37 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 3-35 for more on this, including important safety information. Charging System Light This light will come on brieﬂy when you turn on the ignition, but the engine is not running, as a check to show you it is working. It should go out once the engine is running. If it stays on, or comes on while you are driving, you may have a problem with the charging system. A charging system Driver Information Center (DIC) message may also appear. See DIC Warnings and Messages on page 3-56 for more information. This light could indicate that you have problems with a generator drive belt, or another electrical problem. Have it checked right away. If you must drive a short distance with the light on, be certain to turn off all your accessories, such as the radio and air conditioner. 3-38 If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push, or the pedal may go closer to the ﬂoor. It may take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 4-25. {CAUTION: Your brake system may not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to an accident. If the light is still on after you have pulled off the road and stopped carefully, have the vehicle towed for service. Brake System Warning Light Your vehicle’s hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop you. For good braking, though, you need both parts working well. If the warning light comes on, there is a brake problem. Have your brake system inspected right away. United States Canada This light should come on brieﬂy when you start the engine. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. When the ignition is on, the brake system warning light will also come on when you set your parking brake. The light will stay on if your parking brake does not release fully. If it stays on after your parking brake is fully released, it means you have a brake problem. 3-39 Antilock Brake System Warning Light Traction Control System (TCS) Warning Light For vehicles with the Antilock Brake System (ABS), this light will come on brieﬂy when you start the engine. This warning light should come on brieﬂy when the engine is started. If the warning light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If it stays on, or comes on when you are driving a SERVICE TRACTION CONTROL message will appear in the Driver Information Center (DIC). This indicates that there may be a problem with your traction control system and your vehicle may need service. When this warning light is on and the SERVICE TRACTION CONTROL message appears on the DIC, the system will not limit wheel spin. Adjust your driving accordingly. 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, you still have brakes, but you do not have antilock brakes. If the regular brake system warning light is also on, you do not have antilock brakes and there is a problem with your regular brakes. See Brake System Warning Light on page 3-39 For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-56 for all brake related DIC messages. 3-40 If the traction control system is manually turned off, this light will come on and the TRACTION CONTROL OFF message will appear on the DIC. When the system is active, the light will ﬂash while the system is limiting wheel spin or assisting you in controlling the vehicle. You may also feel or hear the system working. This is normal. See Traction Control System (TCS) on page 4-5 and DIC Warnings and Messages on page 3-56 for more information. StabiliTrak® Indicator Light This warning light should come on brieﬂy when the engine is started. If the light stays on, or comes on when you are driving a SERVICE STABILITRAK message will appear in the DIC. This indicates that there may be a problem with the StabiliTrak® system and your vehicle may need service. When this warning light is on and the SERVICE STABILITRAK message appears on the DIC, the system will not assist you in controlling the vehicle. Adjust your driving accordingly. When the system is active, the light will ﬂash while the system is assisting you in controlling the vehicle. You may also feel or hear the system working. This is normal. See StabiliTrak® System on page 4-6 and DIC Warnings and Messages on page 3-56 for more information. If the warning light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. This light may come on after you ﬁrst start to drive and the STABILITRAK NOT READY message will appear in the Driver Information Center (DIC). See StabiliTrak® System on page 4-6 for more information. 3-41 Lane Departure Warning Light Your vehicle may have the lane departure warning system. Engine Coolant Temperature Warning Light The engine coolant temperature warning light will come on when the engine has overheated. This light will come on green, brieﬂy, when the vehicle is started to show that it is working. This light will also come on green if the system detects a left or right lane marking. This light will change to amber and ﬂash and three beeps will sound if you cross a detected lane marking without using your turn signal. For more information, see the Index in the Navigation Manual. If this happens you should pull over and turn off the engine as soon as possible. See Engine Overheating on page 5-28 for more information. Notice: Driving with the engine coolant temperature warning light on could cause your vehicle to overheat. See Engine Overheating on page 5-28. Your vehicle could be damaged, and it might not be covered by your warranty. Never drive with the engine coolant temperature warning light on. This light will also come on brieﬂy when starting your vehicle. If it does not, have your vehicle serviced. 3-42 Engine Coolant Temperature Gage Tire Pressure Light This light comes on brieﬂy when the engine is started. United States Canada This gage shows the engine coolant temperature. If the pointer moves towards the H (United States) or shaded in thermostat symbol area (Canada), the engine is too hot. A temperature indicator light will turn on and a chime will sound. If you have been operating your vehicle under normal driving conditions, and the temperature indicator light comes on, you should pull off the road, stop your vehicle and turn off the engine as soon as possible. This light will also come on when one or more of your tires are signiﬁcantly underinﬂated. A tire pressure message in the Driver Information Center (DIC), may accompany the light. See DIC Warnings and Messages on page 3-56 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 5-60 for more information. If a problem is detected with the Tire Pressure Monitor System, this light will ﬂash for approximately 60 seconds and then stay on solid for the remainder of the ignition cycle. See Tire Pressure Monitor System on page 5-69 for more information. 3-43 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. 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. If you keep driving your vehicle with this 3-44 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. 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. (cid:129) (cid:129) If the Light is Flashing The following can prevent more serious damage to your vehicle: (cid:129) Reduce vehicle speed. (cid:129) Avoid hard accelerations. (cid:129) 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. Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See Gasoline Octane on page 5-6. 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. 3-45 (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 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. 3-46 Oil Pressure Light {CAUTION: Do not keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches ﬁre. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. Notice: Lack of proper engine oil maintenance may damage the engine. The repairs would not be covered by your warranty. Always follow the maintenance schedule in this manual for changing engine oil. This light will come on brieﬂy when you start your engine. If it does not, have your vehicle serviced. When the light comes on and stays on, it means that oil is not ﬂowing through your engine properly. You could be low on oil and you might have some other system problem. Security Light Cruise Control Light For information regarding this light and the vehicle’s security system, see Content Theft-Deterrent on page 2-17. This light comes on whenever you set the cruise control. Fog Lamp Light The fog lamp light will come on when the fog lamps are in use. The light goes out when the cruise control is turned off. See Cruise Control on page 3-12 for more information. Highbeam On Light This light comes on when the high-beam headlamps are in use. The light will go out when the fog lamps are turned off. See Fog Lamps on page 3-17 for more information. See Headlamp High/Low-Beam Changer on page 3-9 for more information. 3-47 Fuel Gage United States Canada The fuel gage shows about how much fuel is in your tank. It works only when the ignition is on. When the indicator moves to the edge of the low fuel warning band, the low fuel warning light will come on and a chime will sound. You still have a little fuel left, but you need to get more fuel right away. 3-48 Here are some things that some owners ask about. None of these show a problem with your fuel gage: (cid:129) At the service station, the gas pump shuts off before the gage reads full. It takes more (or less) fuel to ﬁll up than the gage indicated. For example, the gage may have indicated half full, but it took more (or less) than half the tank’s capacity to ﬁll it. The gage moves up a little when you turn a corner, speed up or make a hard stop. The gage does not go back to empty when you turn off the ignition. Driver Information Center (DIC) Your vehicle has a Driver Information Center (DIC). All messages will appear in the DIC display located below the speedometer in the instrument panel cluster. The DIC buttons are located on the instrument panel, to the left of 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. (cid:129) (cid:129) (cid:129) The DIC displays trip, fuel, and vehicle system information, and warning messages if a system problem is detected. The bottom line of the DIC shows the shift lever position indicator. See Automatic Transmission Operation on page 2-25 for more information. If your vehicle’s DIC has these features, the compass direction and the outside air temperature may also display on the DIC 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 3-66 for more information. DIC Operation and Displays The DIC has different displays which can be accessed by pressing the DIC buttons located on the instrument panel, to the left of 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, instantaneous economy, and average speed. T (Vehicle Information): Press this button to display the oil life, units, park assist on vehicles with this feature, side blind zone alert on vehicles with this feature, tire pressure readings, compass zone and compass calibration on vehicles with this feature, and Remote Keyless Entry (RKE) transmitter programming. U (Customization): Press this button to customize the feature settings on your vehicle. See DIC Vehicle Customization on page 3-66 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. 3-49 Trip/Fuel Menu Items 3 (Trip/Fuel): Press this button to scroll through the following menu items: Odometer Press the trip/fuel button until ODOMETER displays. This display shows the distance the vehicle has been driven in either miles (mi) or kilometers (km). Trip A and Trip B Press the trip/fuel button until TRIP A or TRIP B displays. This display shows the current distance traveled in either miles (mi) or kilometers (km) 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 miles (mi) or kilometers (km) 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 5 miles (8 km) before it is started again, and then the retro-active reset feature is activated, the display will show 5 miles (8 km). As the vehicle begins moving, the display will then increase to 5.1 miles (8.2 km), 5.2 miles (8.4 km), 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 miles (mi) or kilometers (km) that were driven during the last ignition cycle. 3-50 Fuel Range Press the trip/fuel button until FUEL RANGE displays. This display shows the approximate number of remaining miles (mi) or kilometers (km) the vehicle can be driven without refueling. 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 3-56 for more information. Average Economy Press the trip/fuel button until AVG ECONOMY displays. This display shows the approximate average miles per gallon (mpg) or liters per 100 kilometers (L/100 km). This number is calculated based on the number of mpg (L/100 km) recorded since the last time this menu item was reset. To reset AVG ECONOMY, press and hold the set/reset button. The display will return to zero. Instantaneous Economy Press the trip/fuel button until INST ECONOMY displays. This display shows the current fuel economy at a particular moment and will change frequently as driving conditions change. This display shows the instantaneous fuel economy in miles per gallon (mpg) or liters per 100 kilometers (L/100 km). Unlike average economy, this screen cannot be reset. Average Speed Press the trip/fuel button until AVERAGE SPEED displays. This display shows the average speed of the vehicle in miles per hour (mph) or kilometers per hour (km/h). 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. Blank Display This display shows no information. 3-51 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 3-56. You should change the oil as soon as possible. See Engine Oil on page 5-15. 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 6-4 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. 3-52 It cannot be reset accurately until the next oil change. To reset the engine oil life system, see Engine Oil Life System on page 5-18. 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. Park Assist If your vehicle has the Ultrasonic Rear Parking Assist (URPA) system, this display allows the system to be turned on or off. Press the vehicle information button until PARK ASSIST displays. Once in this display, press the set/reset button to select between ON or OFF. If you choose ON, the system will be turned on. If you choose OFF, the system will be turned off. The URPA system automatically turns back on after each vehicle start. When the URPA system is turned off and the vehicle is shifted out of PARK (P), the DIC will display the PARK ASSIST OFF message as a reminder that the system has been turned off. See DIC Warnings and Messages on page 3-56 and Ultrasonic Rear Parking Assist (URPA) on page 2-39 for more information. Side Blind Zone If your vehicle has the Side Blind Zone Alert (SBZA) system, this display allows the system to be turned on or off. Press the vehicle information button until SIDE BLIND ZONE displays. Once in this display, press the set/reset button to select between ON or OFF. If you choose ON, the system will be turned on. If you choose OFF, the system will be turned off. When the SBZA system is turned off, the DIC will display the SIDE BLIND ZONE ALERT SYSTEM OFF message as a reminder that the system has been turned off. See DIC Warnings and Messages on page 3-56 and Side Blind Zone Alert on page 2-41 for more information. Tire Pressure The pressure for each tire can be viewed in the DIC. The tire pressure will be shown in either pounds per square inch (psi) or kilopascals (kPa). 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 or high 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 5-67 and DIC Warnings and Messages on page 3-56 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. Change Compass Zone Your vehicle may have this feature. To change the compass zone through the DIC, see DIC Compass on page 3-54. 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 3-54. Relearn Remote Key To access this display, the vehicle must be in PARK (P). This display allows you to match Remote Keyless Entry (RKE) transmitters to your vehicle. To match an RKE transmitter to your vehicle: 1. Press the vehicle information button until PRESS V TO RELEARN REMOTE KEY displays.
