To operate the power tilt feature, push the control up or down to tilt the steering wheel up or down. Push the control forward or rearward to move the steering wheel toward the front or rear of the vehicle. The lever on the left side of the steering column includes the following: G : Turn and Lane-Change Signals P : Exterior Lamp Control 3 : Headlamp High/Low-Beam Changer # : Fog Lamps Flash-To-Pass Feature. Information for these features is on the pages following. 3-7 Turn Signal On Chime If the turn signal is left on for about 1 mile (1.6 km), a warning chime will sound and the TURN SIGNAL ON message will appear on the Driver Information Center (DIC) display. See “Turn Signal On” under DIC Warnings and Messages on page 3-57 for more information. Headlamp High/Low-Beam Changer Push forward on the turn signal/multifunction lever to change the headlamps from low to high beam. Pull the lever back and then release it to change from high to low beam. If the vehicle is turned off while the high beams are on, they will come on the next time the vehicle is started. The highbeam light on the instrument panel cluster, comes on while the high-beam headlamps are on. Turn and Lane-Change Signals An arrow on the instrument panel cluster ﬂashes in the direction of the turn or lane change. Move the lever all the way up or down to signal a turn. Raise or lower the lever until the arrow starts to ﬂash to signal a lane change. Hold it brieﬂy until the lane change is complete. The arrow will automatically ﬂash three times. The lever returns to its starting position when it is released. If after signaling a turn or lane change the arrow ﬂashes rapidly or does not come on, a signal bulb may be burned out. Have the bulbs replaced. If the bulb is not burned out, check the fuse. See Fuses and Circuit Breakers on page 5-120. 3-8 Flash-to-Pass This feature allows the high-beam headlamps to be used to signal the driver in front of you that you want to pass. Pull and hold the turn signal/multifunction lever toward you to use this feature. When this is done the following will occur: If the headlamps are off, in low-beam or in Daytime Running Lamps (DRL) mode, the high-beam headlamps will turn on. They will stay on as long as the lever is held there. Release the lever to turn them off. For vehicles with High Intensity Discharge (HID) headlamps, the low-beam headlamps must be on to activate the high-beam headlamps. See High Intensity Discharge (HID) Lighting on page 5-58. If the headlamps are already in high-beam mode, they will remain on high-beam. Windshield Wipers The lever on the right side of the steering column operates the windshield wipers. Move the lever to one of the following positions: 7 (Mist): Pull the lever down and release it for a single wiping cycle. The lever will return to its original position. Hold the lever in this position for continuous wiping cycles. & (Delay): For a delayed wiping cycle. Turn the delay adjustment band to set the length of the delay. 3-9 (cid:129) (cid:129) (cid:129) 6 (Delay Adjustment): Use this band to set the length of the delay between wipes when using the delay feature. The closer the band is moved towards 7 , the longer the delay. The windshield wiper lever must be in delay for this feature to work. 1 (Low Speed): For slow, steady wiping cycles. 2 (High Speed): For rapid wiping cycles. If the windshield wipers are in use for about six seconds while you are driving, the exterior lamps come on automatically if the exterior lamp control is in AUTO. See Wiper Activated Headlamps on page 3-17 for more information. Clear snow and ice from the wiper blades before using them. If the blades are frozen to the windshield, gently loosen or thaw them. If they become damaged, install new blades. For more information, see Windshield Wiper Blade Replacement on page 5-61. Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools down. Rainsense™ Wipers Vehicles with Rainsense windshield wipers, have a moisture sensor for this feature mounted on the interior side of the windshield behind the rearview mirror. This sensor automatically operates the wipers by monitoring the amount of moisture build-up on the windshield. Wipes occur as needed to clear the windshield depending on driving conditions and the sensitivity setting. In light rain or snow, fewer wipes will occur. In heavy rain or snow, wipes occur more frequently. 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 activated. The wiper control should be left in the off position, unless the wiper is needed. The Rainsense system is sensitive to vibration and can activate if something hits the windshield or if the vehicle hits a bump. Rainsense windshield wipers operate in a delay mode, as well as a continuous low or high speed as needed. Move the wiper lever up to the delay position and turn the band to one of ﬁve settings. 3-10 The level one or lowest setting is at the bottom of the band. This setting lets more rain or snow collect on the windshield between wipes. Turn the delay band forward to a higher setting to let less rain or snow collect on the windshield between wipes. The top position is the highest setting. A single wipe occurs each time the delay band is turned to a higher setting to indicate that the Rainsense 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 Rainsense system can be overridden at any time by manually changing the wiper control to low or high speed. The system will default to normal time delay operation if the Rainsensor detects something that would affect Rainsense operation. When Rainsense is active, the headlamps turn on automatically. If it is dark, they remain on. See “Wiper-Activated Headlamps” under Wiper Activated Headlamps on page 3-17 for more information. Notice: Do not place stickers or other items on the exterior glass surface directly in front of the moisture sensor. Doing this could cause the moisture 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. K (Washer Fluid): Press the button with this symbol, located at the end of the windshield washer lever, to wash the windshield. The washer ﬂuid sprays onto the windshield and the wipers run for a few cycles to clear the windshield. Press and hold K for more wash cycles. Washer Fluid Low Add Fluid displays on the Driver Information Center (DIC) when the washer ﬂuid is low. See DIC Warnings and Messages on page 3-57. If the headlamps are on while the windshield is being washed, the headlamp washers, if the vehicle has them, will also turn on. See “Headlamp Washer” following for more information. 3-11 Heated Windshield Washer For vehicles with the heated windshield washer ﬂuid system it can be used to help clear ice, snow, tree sap, or bugs from the windshield. The button is located on the climate control system panel. Push _ to begin four heated wipe cycles. Heating Washer Fluid Wash Wipes Pending displays on the DIC. See DIC Warnings and Messages on page 3-57. The ﬁrst heated wipe cycle can take up to 40 seconds to occur, depending on the outside temperature. After the ﬁrst wipe cycle, it can take up to 20 seconds for each of the remaining cycles. The system will automatically turn off after four wipe cycles have been completed or press _ again to turn it off. Heated Washer Fluid System Off displays on the DIC. See DIC Warnings and Messages on page 3-57. When the heated windshield washer ﬂuid system is activated under certain outside temperature conditions, steam might 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 displays on the DIC when the washer ﬂuid is low. See DIC Warnings and Messages on page 3-57. 3-12 Headlamp Washer Your vehicle may have headlamp washers. The headlamp washers clear debris from the headlamp lenses. Cruise Control { CAUTION: The headlamp washers are located beneath the headlamps. Press the washer button located at the end of the windshield wiper lever, to wash the headlamps. Both the headlamps and the windshield will be washed. After the ﬁrst wash, the headlamps will not be washed until the ﬁfth press of the windshield washer button. The headlamps must be on to be washed. If the headlamps are off, only the windshield will be washed when the washer button is pressed. If the washer ﬂuid is low, the headlamp washers will not work. See Windshield Washer on page 3-11 for more information. Cruise control can be dangerous where you cannot drive safely at a steady speed. 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, the cruise control turns off. If the vehicle has the Stabilitrak® system and begins to limit wheel spin while you are using cruise control, the cruise control will automatically disengage. See StabiliTrak® System on page 4-6. When road conditions allow you to safely use it again, the cruise control can be turned back on. 3-13 The cruise control buttons are located on the 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. CTS Shown, CTS-V Similar I (On/Off): Press to turn the system on or off. The indicator light on the button turns on when cruise control is on. + RES (Resume/Accelerate): Press to make the vehicle accelerate or resume to a previously set speed. 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. 3-14 { 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 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. Resuming a Set Speed Suppose the cruise control is set at a desired speed and then the brake is applied. This shuts off the cruise control. But it does not need to be reset. Once the vehicle is driving at about 25 mph (40 km/h) or more, press the +RES button on the steering wheel. The vehicle goes back to the previously set 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 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’s speed while using cruise control: (cid:129) Press and hold the SET– button on the steering wheel until the desired 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’s speed. When you take your foot off the pedal, the vehicle slows down to the previously set cruise speed. 3-15 (cid:129) (cid:129) Using Cruise Control on Hills How well the cruise control works on hills depends upon the vehicle’s 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 four ways to end cruise control: (cid:129) Step lightly on the brake pedal (manual and automatic transmissions). (cid:129) Press the clutch pedal to the ﬂoor (manual transmissions). (cid:129) Press [ on the steering wheel. (cid:129) Press I 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. Headlamps The exterior lamp control is located towards the end of the turn signal/multifunction lever. O (Exterior Lamp Control): Turn the band with this symbol on it to operate the exterior lamps. The exterior lamp control has four positions: O (Off): Turns off all lamps, except the Daytime Running Lamps (DRL). AUTO (Automatic): Turns the headlamps on and off automatically, depending upon how much light is available outside of the vehicle. ; (Parking Lamps): Turns on the parking lamps together with the following: (cid:129) Sidemarker Lamps Taillamps License Plate Lamps Instrument Panel Lights 5 (Headlamps): Turns on the headlamps, together with the previously listed lamps and lights. 3-16 (cid:129) (cid:129) (cid:129) Wiper Activated Headlamps This feature activates the headlamps and parking lamps after the windshield wipers have been in use for about six seconds. For this feature to work, the exterior lamp control must be in AUTO. The wiper-activated headlamps immediately turn off, when the ignition is turned to LOCK/OFF or the windshield wiper control is turned off. Headlamps on Reminder A warning chime will sound if the exterior lamp control is left on in either the headlamp or parking lamp position and the driver’s door is opened with the ignition off. See Lights On Reminder on page 3-47 for additional information. 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 will make either the reduced intensity low-beam headlamps or dedicated DRL’s come on when the following conditions are met: It is still daylight and the ignition is in ON/RUN or START. The exterior lamp control is in off or AUTO and the headlamps are off. The automatic transmission is not in P (Park). When DRL’s are on, only the reduced intensity low-beam headlamps or dedicated DRL’s will be on. The other exterior lamps and the instrument panel cluster will not be on. 3-17 (cid:129) (cid:129) (cid:129) When the exterior lamp control is in AUTO and it is dark enough outside, the DRL turns off and the low-beam headlamps will turn on. When it is bright enough outside, the low-beam headlamps will go off, and the DRL will turn back on. If the vehicle is started in a dark garage, the automatic headlamp system comes on immediately. Once the vehicle leaves the garage, it takes about one minute 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 lever is in the full bright position. See Instrument Panel Brightness on page 3-20. Turning the exterior lamp control to off or to the low-beam headlamp position will turn off the DRL. If the parking lamps or the fog lamps were turned on instead, the DRL will still turn off. This will work regardless of gear position and whether or not the parking brake is set. Light Sensor The light sensor for the DRL and AUTO headlamp feature is located on top of the instrument panel. If the sensor is covered, it will prevent it from sensing light, and the exterior lamps or the Headlamps Suggested message will appear on the DIC whenever the ignition is on. 3-18 Adaptive Forward Lighting System The Adaptive Forward Lighting System (AFL) pivots the headlamps horizontally to provide greater road illumination while turning. To enable AFL, set the exterior lamp switch on the multifunction lever to the AUTO position. Moving the switch out of the AUTO position will deactivate the system. AFL will operate when the vehicle speed is greater than 2 mph (3 km/h). AFL will not operate when the transmission is in R (Reverse). AFL is not immediately operable after starting the vehicle; driving a short distance is required to calibrate the AFL. See Headlamps on page 3-16. Fog Lamps Use the fog lamps for better vision in foggy or misty conditions. The fog lamp control is located on the turn signal/multifunction lever. # (Fog Lamps): Turn the fog lamp band on the lever up to # and release it, to turn the fog lamps on or off. The band will return to its original position. The parking lamps must be on for the fog lamps to work. If the high-beam headlamps are turned on, the fog lamps will also turn off. They will turn back on again when you change back to low-beam headlamps. Some localities have laws that require the headlamps to be on along with the fog lamps. Exterior Lighting Battery Saver The exterior lamps turn off about 10 minutes after the ignition is turned to LOCK/OFF, if the parking lamps or headlamps have been left on. This protects against draining the battery. The battery saver does not work if the headlamps are turned on after the ignition is turned to LOCK/OFF. To keep the lamps on for more than 10 minutes, turn the lamps back on with the exterior lamp control. 3-19 Parade Dimming This feature does not let the instrument panel backlight dim during daylight hours while the key is in the ignition and the headlamps are on. Parade dimming automatically works with the light sensor, located on top of the dashboard. If it is dark enough outside and the parking lamps are on, the backlight on the instrument panel can be adjusted by turning the instrument panel brightness knob clockwise or counterclockwise to brighten or dim the lighting. See Instrument Panel Brightness on page 3-20. Reading Lamps The reading lamps are located on the overhead console. These lamps come on automatically when any door is opened. For manual operation, press the button next to each lamp to turn it on or off. If the reading lamps are left on, they automatically shut off 10 minutes after the ignition has been turned off. Instrument Panel Brightness The knob with this symbol is located on the instrument panel to the left of the steering column. Turn the knob clockwise or counterclockwise to brighten or dim the lights. Turn the knob completely clockwise to turn on the interior lamps. Entry Lighting The entry lighting system turns on the reading and dome lamps and the backlighting to the exterior lamp control, when a door is opened or if the transmitter unlock button is pressed. If activated by the transmitter, the lighting stays on for about 25 seconds. The entry lighting system uses the light sensor on the instrument panel; so it must be dark outside in order for the lamps to turn on. The lamps turn off about 25 seconds after the last door is closed. They dim then turn off if the ignition key is turned to ON/RUN. They immediately turn off if the power locks are used. 3-20 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. A high electrical load occurs when several of the following are on, such as: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. EPM works to prevent excessive discharge of the battery. It does this by balancing the generator’s output and the vehicle’s electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as BATTERY SAVER ACTIVE, BATTERY VOLTAGE LOW, or LOW BATTERY. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages on page 3-57. Battery Run-Down Protection This feature helps to prevent battery drain if accessory lamps are left on. If accessory lamps such as the vanity mirror, cargo, reading, console, or glove box are left on, they automatically time-out after about 20 minutes. To reset the battery protection, all of the above lamps must be turned off or the ignition must be in the ACC/ACCESSORY position. 3-21 Accessory Power Outlet(s) Accessory power outlets can be used to connect auxiliary electrical equipment, such as a cellular telephone. There are three accessory power outlets. There is an outlet located in the front storage area below the climate control system, one inside the center console storage bin, and one on the rear of the center console. To use an outlet, remove the protective cap. When not in use, always cover the outlet with the protective cap. The accessory power outlet is operational at all times. Notice: If electrical devices are left plugged into a power outlet, the battery may drain causing the vehicle not to start or damage to the battery. This would not be covered by the warranty. Always unplug all electrical devices when turning off the vehicle. Certain electrical accessories may not be compatible with 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 accessory power outlets. 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. Notice: damage not covered by the warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only. Improper use of the power outlet can cause 3-22 Ashtray(s) and Cigarette Lighter The vehicle may have two removable ashtrays and cigarette lighters. One ashtray can be placed into the instrument panel storage compartment and the other into the center console rear compartment. To use the lighter, push it in all the way and let go. When it is ready, it will pop back out by itself. To empty the ashtrays, hold on to the edges of the bin and pull straight out. To reinstall, push the tray back into place. Notice: Holding a cigarette lighter in while it is heating does not let the lighter back away from the heating element when it is hot. Damage from overheating can occur to the lighter or heating element, or a fuse could be blown. Do not hold a cigarette lighter in while it is heating. Notice: are put in the ashtray, hot cigarettes or other smoking materials could ignite them and possibly damage the vehicle. Never put ﬂammable items in the ashtray. If papers, pins, or other ﬂammable items Analog Clock The analog clock is located on the instrument panel above the radio. The clock is not connected with any other vehicle system and runs by itself. To adjust the clock: 1. Locate the adjustment buttons directly below the clock face. 2. Push and hold the right adjustment button to move the clock hands forward or the left adjustment button to make the clock hands go backward. Holding either button down will cause the clock to advance faster. Release the button before the desired time is reached. 3. Push and release either button to adjust the time by one minute increments until the desired time is reached. 3-23 Climate Controls Automatic Operation Dual Climate Control System The heating, cooling, and ventilation for the vehicle can be controlled with this system. A. Display B. Fan Control C. Power D. AUTO E. PASS (Passenger Climate Control) F. Defrost G. Air Delivery Mode Control 3-24 H. Temperature Control and Heated Seat I. Air Conditioning J. Recirculation/ Outside Air K. Heated Windshield Washer L. Rear Window Defogger AUTO (Automatic): The system automatically controls fan speed, air delivery, and air conditioning in order to heat or cool the vehicle to the desired temperature. When the indicator light is on, the system is in full automatic operation. If the air delivery mode or fan setting is manually adjusted, the auto indicator turns off and displays will show the selected settings. 1. Press the AUTO button. 2. Adjust the temperature to a comfortable setting between 70°F (21°C) and 80°F (27°C). Choosing the coldest or warmest temperature setting will not cause the system to heat or cool any faster. If the system is set at the warmest temperature setting, it remains in manual mode at that temperature and it will not go into automatic mode. To avoid blowing cold air in cold weather, the system delays turning on the fan until warm air is available. The system starts out blowing air at the ﬂoor, but can automatically change modes as the vehicle warms up to maintain the chosen temperature setting. The length of time needed for warm up depends on the outside temperature and the length of time that has elapsed since the vehicle was last driven. 3. Wait for the system to regulate. This may take from 10 to 30 minutes. Then adjust the temperature, if necessary. English can be changed to metric units through the Driver Information Center (DIC). See DIC Vehicle Customization on page 3-71. Q / R (Temperature Control): The temperature can be adjusted separately for the driver and the passenger. Press to increase or decrease the automatic temperature settings. PASS (Passenger Climate Control): Press to set a different temperature for the passenger. Then adjust the passenger temperature buttons to a comfortable setting. Pressing the PASS button again automatically sets the passenger’s temperature to the driver’s setting. Turning the passenger’s temperature display off does not shut the passenger’s climate control system off. Manual Operation O (Power): Press to turn the climate control system on or off. When the climate control system is turned off the air inlet defaults to outside air. D C (Fan Control): Press the buttons to increase or decrease the fan speed. Pressing either button cancels automatic operation and the system goes into manual mode. Press AUTO to return to automatic operation. The blower may reduce during an Onstar® session to limit background noise. If the airﬂow seems low when the fan speed is at the highest setting, the passenger compartment air ﬁlter might need to be replaced. For more information, see Passenger Compartment Air Filter on page 3-29 and Scheduled Maintenance on page 6-4. H G (Air Delivery Mode Control): Press the buttons to change the direction of the airﬂow. The current mode appears in the display screen. Changing the mode cancels the automatic operation and the system goes into manual mode. Press AUTO to return to automatic operation. The outboard air outlets always receive some airﬂow in every mode, except defrost. 3-25 To change the current mode, select one of the following: Y (Vent): Air is directed to the instrument panel outlets. \ (Bi-Level): Air is divided 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. [ (Floor): Air is directed to the ﬂoor outlets, with some air directed to the windshield and outboard outlets. - (Defog): This mode clears the windows of fog or moisture. Air is directed to the windshield, ﬂoor and side window outlets. 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. If recirculation is selected while in defog mode, it is cancelled after 10 minutes. 0 (Defrost): This mode clears the windshield of fog or frost more quickly. Air is directed to the windshield, with some air directed to the side windows. In this mode, the system automatically turns off recirculation and runs the air-conditioning compressor, unless the outside temperature is at or below freezing. This mode can also cause the fan speed and air temperature to increase. # (Air Conditioning): Press to turn the air conditioning system on or off and override the automatic system. When in AUTO, the air conditioning compressor comes on automatically, as needed. The air conditioning system removes moisture from the air, so a small amount of water might drip under the vehicle while idling or after turning off the engine. This is normal. 3-26 M / F (Recirculation/Outside Air): Press this button to switch between recirculation and outside air modes. The indicator light comes on to show which mode is being used. The recirculation mode recirculates and helps to quickly cool the air inside the vehicle. It can be used to prevent outside air and odors from entering the vehicle. Press the auto button to have the system select the best air delivery mode for the temperature setting. Recirculation is not available in the defrost mode and automatically turns off 10 minutes after defog is selected. This helps to limit window fogging in the vehicle. Using recirculation for long periods of time could cause the air inside the vehicle to become too dry or stuffy. To prevent this from happening, after the air in the vehicle has cooled, select outside air or press the auto button. The outside air mode pulls fresh air from outside the vehicle. Outside air is always selected in defrost mode to prevent fogging. Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. It only works when the ignition is in ON/RUN. = (Rear Window Defogger): Press to turn the rear window defogger on or off. The rear window defogger stays on for about 15 minutes, before turning off if the vehicle is moving at a slower speed. At higher speeds, the rear window defogger may stay on continuously. With each additional press, the defogger runs for about 10 minutes. The defogger can also be turned off by turning off the engine. The heated outside rearview mirrors turn on when the rear window defogger button is on and helps to clear fog or frost from the surface of the mirror. See Outside Heated Mirrors on page 2-54. Notice: Do not try to clear frost or other material from the inside of the front windshield and rear window with a razor blade or anything else that is sharp. This may damage the rear window defogger grid and affect your radio’s ability to pick up stations clearly. The repairs wouldn’t be covered by your warranty. Heated and Ventilated Seats: Press to heat or ventilate the seat. See Heated and Ventilated Seats on page 1-7. 3-27 _ (Heated Windshield Washer, If Equipped): For more information, see Windshield Washer on page 3-11. Remote Start Climate Control Operation: For vehicles with remote vehicle start feature and it is activated, the climate control system heats and cools the inside of the vehicle using the previous settings of the system before the vehicle was turned off. See Remote Vehicle Start on page 2-15. The windshield defroster and/or rear window defogger turn on if it is cold outside. If the vehicle has heated seats, they turn on if the temperature inside the vehicle is cooler than 54°F (12.5°C) or if the outside temperature is cooler than 48°F (9°C). Sensors The solar sensor located on the instrument panel, near the windshield, monitors the solar heat. The interior temperature sensor located on the instrument panel to the right of the steering wheel, measures the temperature of the air inside the vehicle. The climate control system uses the information from these sensors to adjust the fan speed and the air delivery, in order to maintain the selected temperature. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be activated, as necessary. Do not cover the sensors or the automatic climate control system will not work properly. 3-28 Outlet Adjustment Use the air outlets located in the center and on the side of the instrument panel to direct the airﬂow. Use the thumbwheels near the air outlets to open or close off the airﬂow. Operation Tips (cid:129) Clear away any ice, snow, or leaves from air inlets at the base of the windshield that could block the ﬂow of air into the vehicle. (cid:129) Keep the path under the front seats clear of objects to help circulate the air inside of the vehicle more effectively. (cid:129) Use of non-GM approved hood deﬂectors can adversely affect the performance of the system. Check with your dealer/retailer before adding equipment to the outside of the vehicle. Passenger Compartment Air Filter The passenger compartment air ﬁlter traps most of the dust and pollen from the air entering the vehicle. The ﬁlter will need to be changed periodically. See Scheduled Maintenance on page 6-4. Using the climate control system without the passenger air ﬁlter installed could let water or other debris enter the system. This could cause a water leak or noises. Make sure a new air ﬁlter is installed after removing the old one. The passenger compartment air ﬁlter is located under the hood below the windshield wiper arm and the screen on the passenger side of the vehicle.

Warning Lights, Gages, and Indicators Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to the warning lights and gages could prevent injury. Warning lights come on when there may be or is a problem with one of the vehicle’s functions. Some warning lights come on brieﬂy when the engine is started to indicate they are working. Gages can indicate when there may be or is a problem with one of the vehicle’s functions. Often gages and warning lights work together to indicate a problem with the vehicle. When one of the warning lights comes on and stays on while driving, or when one of the gages shows there may be a problem, check the section that explains what to do. Follow this manual’s advice. Waiting to do repairs can be costly and even dangerous. 3-30 Instrument Panel Cluster The instrument panel cluster is designed to indicate how the vehicle is running. It shows how fast the vehicle is going, how much fuel the vehicle has used and many of the other things needed to drive safely and economically. United States Automatic Transmission Cluster shown, Manual and Canada similar 3-31 United States V–Series Automatic Transmission Cluster shown, Manual and Canada similar 3-32 Speedometer and Odometer The speedometer shows the vehicle speed in either miles per hour (mph) or kilometers per hour (km/h). The odometer shows how far the vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). If the vehicle has to have a new odometer installed, the new one may read the correct mileage. This is because the vehicle computer has stored the mileage in memory. While the Driver Shift Control (DSC) feature is active, the odometer changes to show the gear range. See Automatic Transmission Operation on page 2-37 for more information. Trip Odometers The trip odometer can record the number of miles or kilometers traveled for up to two trips. The trip odometer is part of the Driver Information Center (DIC), for more information see DIC Operation and Displays on page 3-50. For vehicles that have the navigation system, see your Navigation System manual for more information. Tachometer United States and Canada Automatic, V-Series Similar If the engine is operated with the The tachometer displays the engine speed in revolutions per minute (rpm). Notice: tachometer in the shaded warning area, the vehicle could be damaged, and the damages would not be covered by the vehicle warranty. Do not operate the engine with the tachometer in the shaded warning area. The CTS-V tachometer has tracer lights that follow the movement of the tachometer indicator. 3-33 The safety belt light comes on and stays on for several seconds, then ﬂashes for several more. This chime and light are repeated if the driver remains unbuckled and the vehicle is in motion. 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. This only occurs if the passenger airbag is enabled. See Passenger Sensing System on page 1-63 for more information. The passenger safety belt light, located on the instrument panel, comes on and stays on for several seconds and then ﬂashes for several more. For the CTS-V, the tracer lights also ﬂash when it is time to up-shift to avoid the engine speed limit. See Automatic Transmission Operation on page 2-37 or Manual Transmission Operation on page 2-42 for more information. Engine Speed Limiter This feature prevents the engine speed from reaching an unsafe level. If the level is too high, the throttle closes or limits the fuel supply until the engine speed returns to a safe level. Throttle operation and fuel supply returns to normal when engine speed is lowered. For the CTS-V, the tachometer tracer lights ﬂashes prior to reaching engine speed limit. The tracer lights also ﬂash on automatic transmission vehicles while in the DSC or Tap Shift modes. Safety Belt Reminders Safety Belt Reminder Light When the engine is started, a chime sounds for several seconds to remind a driver to fasten the safety belt, unless the driver safety belt is already buckled. 3-34 This chime and light are repeated if the passenger remains unbuckled and the vehicle is in motion. The airbag readiness light ﬂashes for a few seconds when the engine is started. If the light does not come on then, have it ﬁxed immediately. If the passenger safety belt is buckled, neither the chime nor the light comes on. The front passenger safety belt warning light and chime may turn on if an object is put on the seat such as a briefcase, handbag, grocery bag, laptop or other electronic device. To turn off the warning light and or chime, remove the object from the seat or buckle the safety belt. Airbag Readiness Light The system checks the airbag’s electrical system for possible malfunctions. If the light stays on it indicates there is an electrical problem. The system check includes the airbag sensor, the pretensioners, the airbag modules, the wiring and the crash sensing and diagnostic module. For more information on the airbag system, see Airbag System on page 1-55. { CAUTION: If the airbag readiness light stays on after the vehicle is started or comes on while driving, it means the airbag system might not be working properly. The airbags in the vehicle might not inﬂate in a crash, or they could even inﬂate without a crash. To help avoid injury, have the vehicle serviced right away. If there is a problem with the airbag system, an airbag Driver Information Center (DIC) message can also come on. See DIC Warnings and Messages on page 3-57 for more information. 3-35 Passenger Airbag Status Indicator The vehicle has the passenger sensing system. See Passenger Sensing System on page 1-63 for important safety information. The instrument panel has a passenger airbag status indicator. 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 passenger 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. United States Canada { CAUTION: 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. If you are using remote start to start the vehicle from a distance, if equipped, you may not see the system check. Then, after several more seconds, the status indicator will light either ON or OFF, or either the on or off symbol, to let you know the status of the right front passenger frontal airbag. 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 3-35 for more information, including important safety information. 3-36 Charging System Light Up-Shift Light 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. The vehicle may have an up-shift light, it shows when to shift to the next higher gear for best fuel economy. 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 3-57 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. See Manual Transmission Operation on page 2-42 for more information. For the CTS-V, the tracer lights function as a performance up-shift light. These tracers ﬂash to indicate when to shift to the next higher gear to avoid the engine speed limit. See Automatic Transmission Operation on page 2-37 or Manual Transmission Operation on page 2-42 for more information. 3-37 Brake System Warning Light This 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 parts need to be working well. If the warning light comes on, there is a brake problem. Have the brake system inspected right away. United States Canada This light should come on brieﬂy when the ignition is turned to ON/RUN. If it does not come on then, have it ﬁxed so it will be ready to warn if there is a problem. When the ignition is on, the brake system warning light will also come on when the parking brake is set. The light will ﬂash or stay on if the parking brake is not fully released. 3-38 If the light stays on after the parking brake is fully released there is a base brake problem. For vehicles with the Electric Park Brake (EPB), if the light continues ﬂashing after the brake is released, or while driving, there is a problem with the Electric Parking Brake system. If the light comes on while driving, pull off the road and stop carefully. The pedal may be harder to push, or the pedal may go closer to the ﬂoor. The vehicle may take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 4-26. { CAUTION: 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. For vehicles with the Electric Park Brake (EPB), this light should come on brieﬂy when ignition is turned to ON/RUN. If it does not come on then, have it ﬁxed so it will be ready to warn if there is a problem. If this light comes on there is a problem with a system on the vehicle that is causing the park brake system to work at a reduced level. The vehicle can still be driven, but should be taken to a dealer/retailer as soon as possible. See Electric Parking Brake on page 2-45 for more information. Antilock Brake System (ABS) Warning Light For vehicles with the Antilock Brake System (ABS), this light comes on brieﬂy when the engine is started. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the ABS light stays on, turn the ignition off. If the light comes on while driving, stop as soon as it is safely possible and turn the ignition off. Then start the engine again to reset the system. If the ABS light stays on, or comes on again while driving, the vehicle needs service. If the regular brake system warning light is not on, the vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, the vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 3-38. For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-57 for all brake related DIC messages. 3-39 StabiliTrak®/Traction Control System (TCS) Warning Light Engine Coolant Temperature Warning Light The Traction Control System (TCS)/StabiliTrak warning light should come on brieﬂy when the engine is started. The engine coolant temperature warning light comes on brieﬂy when the engine is started. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the light comes on or stays on while driving, there may be a problem with the TCS/StabiliTrak and the vehicle may need service. When this warning light is on, the system does not limit wheel spin. Adjust driving accordingly. See Traction Control System (TCS) on page 4-7 and StabiliTrak® System on page 4-6 for more information. 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 while driving, the vehicle may have a problem with the cooling system. Stop the vehicle and turn off the engine as soon as possible to avoid damage to the engine. A warning chime sounds when this light is on. See Engine Overheating on page 5-38 for more information. 3-40 Engine Coolant Temperature Gage Tire Pressure Light United States Canada This gage shows the engine coolant temperature. If the engine coolant overheats the engine coolant temperature warning light will come on. See Engine Overheating on page 5-38 and Engine Coolant Temperature Warning Light on page 3-40 for more information. 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. When the Light is On Steady This indicates that one or more of the tires is signiﬁcantly underinﬂated. A tire pressure message in the Driver Information Center (DIC), can accompany the light. See DIC Warnings and Messages on page 3-57 for more information. Stop and check the tires as soon as it is safe to do so. If a tire is underinﬂated, inﬂate to the proper pressure. See Tires on page 5-63 for more information. 3-41 When the Light Flashes First and Then is On Steady This indicates that there could be a problem with the Tire Pressure Monitor System. The light ﬂashes for about a minute and stays on steady for the remainder of the ignition cycle. This sequence repeats with every ignition cycle. See Tire Pressure Monitor System on page 5-75 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 makes sure 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 come on, have the vehicle serviced by your dealer/retailer. 3-42 If the check engine light comes on and stays on, while the engine is running, this indicates that there is an OBD II problem and service is required. Malfunctions often are indicated by the system before any problem is apparent. Being aware of the light can prevent more serious damage to the vehicle. This system assists the service technician in correctly diagnosing any malfunction. Notice: If the vehicle is continually driven with this light on, after a while, the emission controls might not work as well, the vehicle’s fuel economy might not be as good, and the engine might not run as smoothly. This could lead to costly repairs that might not be covered by the vehicle warranty. Notice: Modiﬁcations made to the engine, transmission, exhaust, intake, or fuel system of the vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect the vehicle’s emission controls and can cause this light to come on. Modiﬁcations to these systems could lead to costly repairs not covered by the vehicle warranty. This could also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modiﬁcations on page 5-4. 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. The following can prevent more serious damage to the vehicle: (cid:129) Reduce vehicle speed. (cid:129) Avoid hard accelerations. (cid:129) Avoid steep uphill grades. If the light continues to ﬂash, when it is safe to do so, stop the vehicle. Find a safe place to park the vehicle. Turn the key off, wait at least 10 seconds, and restart the engine. If the light is still ﬂashing, follow the previous steps and see your dealer/retailer for service as soon as possible. Light On Steady: An emission control system malfunction has been detected on the vehicle. Diagnosis and service might be required. An emission system malfunction might be corrected by doing the following: (cid:129) Make sure the fuel cap is fully installed. See Filling the Tank on page 5-9. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap allows fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. If the vehicle has been driven through a deep puddle of water, the vehicle’s electrical system might be wet. The condition is usually corrected when the electrical system dries out. A few driving trips should turn the light off. (cid:129) Make sure to fuel the vehicle with quality fuel. Poor fuel quality causes the engine not to run as efficiently as designed and may cause: stalling after start-up, stalling when the vehicle is changed into gear, misﬁring, hesitation on acceleration, or stumbling on acceleration. These conditions might go away once the engine is warmed up. If one or more of these conditions occurs, change the fuel brand used. It will require at least one full tank of the proper fuel to turn the light off. See Gasoline Octane on page 5-6. 3-43 (cid:129) 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. 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 the ON/RUN and the light is not on. For vehicles with a Keyless Access ignition, make sure the transmitter is in the passenger compartment. See Ignition Positions (Key Access) on page 2-32 or Ignition Positions (Keyless Access) on page 2-33. 3-44 (cid:129) (cid:129) { CAUTION: Do not keep driving if the oil pressure is low. The engine can become so hot that it catches ﬁre. Someone could be burned. Check the oil as soon as possible and have the vehicle serviced. Notice: Lack of proper engine oil maintenance can damage the engine. The repairs would not be covered by the vehicle warranty. Always follow the maintenance schedule in this manual for changing engine oil. Oil Pressure Light For vehicles with an oil pressure light, if there is a problem with the oil, the light may stay on after the engine is started, or comes on while driving. This light indicates that oil is not going through the engine quickly enough to keep it lubricated. The engine could be low on oil or could have some other oil problem. Have the vehicle serviced by your dealer/retailer. The oil light could also come on in the following situations: The light comes on brieﬂy when the ignition is turned on to show that it is working properly. If it does not come on with the ignition on, there may be a problem with the fuse or bulb. Have the vehicle serviced by your dealer/retailer. (cid:129) Sometimes when the engine is idling at a stop, a chime sounds and the light may blink on and off. This is normal. 3-45 (cid:129) A reading outside the normal operating range may be caused by a dangerously low oil level or some other problem causing low oil pressure. Oil should be checked as soon as possible. See Oil pressure Low Stop Engine under DIC Warnings and Messages on page 3-57 and Engine Oil on page 5-18. { CAUTION: Do not keep driving if the oil pressure is low. The engine can become so hot that it catches ﬁre. Someone could be burned. Check the oil as soon as possible and have the vehicle serviced. Notice: Lack of proper engine oil maintenance can damage the engine. The repairs would not be covered by the vehicle warranty. Always follow the maintenance schedule in this manual for changing engine oil. Engine Oil Pressure Gage United States Canada For vehicles with an engine oil pressure gage. It 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 if readings are outside the normal operating range, the oil pressure light will come on. See Oil Pressure Light on page 3-45 for more information. 3-46 Security Light Lights On Reminder For information regarding this light and the vehicle’s security system, see Theft-Deterrent System on page 2-27. This light comes on whenever the parking lamps are on. Fog Lamp Light The fog lamp light comes on when the fog lamps are in use. See Headlamps on Reminder on page 3-17 for more information. Cruise Control Light The cruise control light comes on whenever the cruise control is set. The light goes out when the fog lamps are turned off. See Fog Lamps on page 3-19 for more information. The light goes out when the cruise control is turned off. See Cruise Control on page 3-13 for more information. 3-47 Highbeam On Light This light comes on when the high-beam headlamps are in use. See Headlamp High/Low-Beam Changer on page 3-8 for more information. Fuel Gage The fuel gage shows approximately how much fuel is in the fuel tank. It works only when the ignition is in the ON/RUN position. An arrow on the fuel gage indicates the side of the vehicle the fuel door is on. If the fuel supply gets low, the Fuel Level Low message will appear on the Driver Information Center (DIC) and a single chime will sound. See DIC Warnings and Messages on page 3-57 for more information. Here are a few concerns some owners have had about the fuel gage. All of these situations are normal and do not indicate that anything is wrong with the fuel gage: (cid:129) At the gas station the gas pump shuts off before the gage reads full. The gage may change when you turn, stop quickly or accelerate quickly. It takes a little more or less fuel to ﬁll the tank than the gage indicated. For example, the gage may have indicated that the tank was half full, but it actually took a little more or less than half the tank’s capacity to ﬁll the tank. 3-48 (cid:129) (cid:129) Boost Gage United States Canada For the CTS-V, this gage is located in the instrument panel cluster. This gage indicates positive manifold pressure which is the induction air pressure level in the intake manifold before it enters the combustion chamber. This gage reads zero under light throttle before boost is generated. This gage automatically resets to zero every time the engine is started. Driver Information Center (DIC) The Driver Information Center (DIC) gives you the status of many of your vehicle’s systems. The DIC is also used to display warning/status messages. All messages 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 steering wheel. The DIC comes on when the ignition is on. After a short delay, the DIC displays the information that was last displayed before the engine was turned off. The top line of the DIC display shows the DIC information. The bottom line of the DIC display shows the compass. The compass displays in the trip/fuel menus and in some vehicle information menus. If a problem is detected, a warning message appears on the display. Take any message that appears on the display seriously and remember that clearing the message only makes the message disappear, and does not correct the problem. 3-49 DIC Operation and Displays The Driver Information Center (DIC) has different displays which can be accessed by pressing the DIC buttons located on the instrument panel, next to the steering wheel. 3 Trip/Fuel: Press this button to scroll through the trip and fuel displays.

Trip/Fuel Display Menu Items 3 (Trip/Fuel): The following display menu items can be displayed by pressing the trip/fuel button: Odometer This display shows the distance the vehicle has been driven in either miles (mi) or kilometers (km). Trip A or Trip B These displays show the current distance traveled since the last reset for each trip odometer in either miles (mi) or kilometers (km). Both odometers can be used at the same time. Each trip odometer can be reset to zero separately by pressing and holding the set/reset button for a few seconds while the desired trip odometer is displayed. Fuel Range This display shows the approximate number of remaining miles (mi) or kilometers (km) you can drive without reﬁlling the fuel tank. This estimate is based on the current driving conditions and changes if the driving conditions change. For example, if you are driving in traffic and making frequent stops, the display may read one number, but if you enter the freeway, the number may change even though you still have the same amount of fuel in the fuel tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving. Once the range drops below about 30 miles (48 km) remaining, the display shows Low Range. If the vehicle is low on fuel, the Fuel Level Low message displays. See “Fuel Level Low” under DIC Warnings and Messages on page 3-57 for more information. AVG (Average) Economy 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 display was reset. To reset this display to zero, press the set/reset button.

Blank Display This display shows no information. 3-54 DIC Compass The vehicle may have a compass in the Driver Information Center (DIC). Compass Zone The zone is set to zone eight. If you do not live in zone eight or drive out of the area, the variance needs to be changed to the appropriate zone. 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. On an automatic transmission vehicle, only set it when the vehicle is in P (Park). On a manual transmission vehicle, only set it when the vehicle is stopped. 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. Calibrate the compass. See “Compass Calibration Procedure” following. 3-55 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 appears 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. Interference may be caused by a magnetic antenna mount, 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, check that the compass is set to the correct variance zone. See “Compass Variance (Zone) Procedure” earlier in this section. Do not operate any switches such as window, sunroof, climate controls, seats, etc. during the calibration procedure. 2. Press the 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. 3-56 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 V (Set/Reset) 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.
