URPA can detect objects 3 inches (7.6 cm) and wider, and at least 10 inches (25.4 cm) tall, but it cannot detect objects that are above trunk level. In order for the rear sensors to recognize an object, it must be within operating range.


If the URPA system is not functioning properly, the display will flash red, indicating that there is a problem. The light will also flash red while driving if a trailer is attached to your vehicle, or a bicycle or object is on the back of, or hanging out of your trunk. The light will continue to flash until the trailer or the object is removed and your vehicle is driven forward at least 15 mph (25 km/h). It may also flash red if the ultrasonic sensors are not kept clean. So be sure to keep your rear bumper free of mud, dirt, snow, ice and slush or materials such as paint or the system may not work properly. If after cleaning the rear bumper and driving forward at least 15 mph (25 km/h), the display continues to flash red, see your dealer. For cleaning instructions, see Cleaning the Outside of Your Vehicle on page5-78. It may also flash red if your vehicle is moving in REVERSE (R) at a speed greater than 3 mph (5 km/h). Other conditions that may affect system performance include things like the vibrations from a jackhammer or the compression of air brakes on a very large truck. As always, drivers should use care when backing up a vehicle. Always look behind you, being sure to check for other vehicles, obstructions and blind spots.

Ashtrays and Cigarette Lighter The ashtray and cigarette lighter are located under a lid in the front console to the right of the shift lever. Press the left side of the lid and it will open automatically. Notice: If you put papers or other flammable 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. Loose objects (such as paper clips) can lodge behind and beneath the ashtray lid and prevent movement of the lid. You should avoid putting small, loose objects near the ashtray. To use the cigarette lighter, push it in all the way and let go. When it’s ready, it will pop back out by itself. Notice: Holding a cigarette lighter in while it is heating will not allow the lighter to back away from the heating element when it is hot. Damage from overheating may occur to the lighter or heating element, or a fuse could be blown. Do not hold a cigarette lighter in while it is heating.


Climate Controls


Dual Climate Control System With this system you can control the heating, cooling and ventilation for your vehicle.


When your vehicle is first started, the system will recall the last temperature fan and mode settings for that driver.

Automatic Operation


AUTO (Automatic): When this button is pressed and the temperature is set, the system will automatically control the inside temperature, the air delivery mode, the air-conditioning compressor and the fan speed. AUTO will appear on the display. 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 warmest or coldest temperature setting will not cause the system to heat or cool any faster. If you set the system at the warmest or coldest temperature setting, the system will remain in manual mode at that temperature and it will not go into automatic mode. In cold weather, the system will start at reduced fan speeds at avoid blowing cold air into your vehicle until warmer air is available. The system will start out blowing air at the floor but may change modes automatically as the vehicle warms up to maintain the chosen temperature setting. The length of time needed for warm up will depend on the outside temperature and the length of time that has elapsed since your 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.


3-36


You can switch from English to metric units through the Driver Information Center (DIC). See DICControls andDisplaysonpage3-57 for more information. The air-conditioning system removes moisture from the air, so you may sometimes notice a small amount of water dripping underneath your vehicle while idling or after turning off the engine. This is normal. 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. Manual Operation w PWR x (Power/Temperature): Press the PWR button on the left side of the climate control panel to turn the entire climate control system on or off. Press the up or down arrow on the switch to manually increase or decrease the temperature inside the vehicle.


Press the PWR button on the right side of the climate control panel to turn the passenger’s climate control system on or off. Press the up or down arrow on the switch to manually increase or decrease the temperature for the passenger.


If the passenger’s PWR button is off, the driver’s temperature switch controls the temperature for the entire vehicle.


«9“(Fan): Press this switch to increase or decrease the fan speed. Pressing this switch cancels automatic operation and places the system in manual mode. Press AUTO to return to automatic 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 PassengerCompartmentAirFilteronpage3-40
and Scheduled Maintenance on page6-4. “N« (Mode): Pressing the switch and changing the mode cancels automatic operation and places the system in manual mode. Press the AUTO button to return to automatic operation.


To change the current mode, select one of the following: H (Vent): This mode directs air to the instrument panel outlets. % (Bi-Level): This mode directs approximately half of the air to the instrument panel outlets, and then directs most of the remaining air to the floor outlets. In automatic operation, cooler air is directed to the upper outlets and warmer air to the floor outlets.


6 (Floor): This mode directs most of the air to the floor outlets with some air directed to the side window outlets, and a little air directed to the windshield.


The mode switch can also be used to select the defog mode. Information on defogging and defrosting can be found later in this section.


A/C OFF (Air Conditioning): Press this button to turn off the air conditioning compressor. Press AUTO to return to automatic operation. The compressor cannot be turned off in either the defrost or floor/defog mode. ( (Heated/Cooled Seat): Press this button to turn the feature on. The button on the left controls the driver’s seat and the button on the right controls the passenger’s seat. Each press of the button will take you to a different setting. The settings available in order are HI HEAT, LO HEAT, OFF, HI COOL, LO COOL and OFF. You will be able to feel the temperature change in a few minutes.


The feature will automatically shut off when the vehicle is turned off.


3-37


? (Recirculation): Press this button to turn the recirculation mode on or off. The air-conditioning compressor also comes on. This mode keeps outside air from coming in the vehicle. It can be used to prevent outside air and odors from entering your vehicle or to help cool the air inside your vehicle more quickly.


Recirculation is not available in defrost or floor/defog mode.


Using recirculation for long periods of time may cause the air inside your vehicle to become too dry. To prevent this from happening, after the air in your vehicle has cooled, turn the recirculation mode off. Sensors There are sensors to measure the temperature and sun’s effect on passenger comfort. The solar sensor on your vehicle monitors the solar radiation then uses the information to maintain the selected temperature when operating in AUTO mode by initiating needed adjustments to the temperature, the fan speed and the air delivery system. 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 solar sensor located on the top right side of the instrument panel near the windshield or system will not work properly.


3-38


There is also a sensor located behind the front bumper. This sensor reads the outside air temperature and helps maintain the temperature inside the vehicle. The outside temperature will be displayed in the navigation system only when the engine is running. Any cover on the front of the vehicle could give a false reading of the temperature. If the outside temperature goes up, the display temperature will not change until: • The vehicle’s speed is above 10 mph (16 km/h) for


five minutes.


• The vehicle’s speed is above 32 mph (51 km/h) for


two and one-half minutes.


These delays prevent false readings. If the temperature goes down, the outside temperature will be shown when you start the vehicle. If it has been turned off for less than three hours, the temperature will be recalled from the previous vehicle operation. There is also an inside temperature sensor located to the left of the ignition button. The automatic climate control system uses this sensor to receive information, so if you block or cover it, the system will not function properly.


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 or frost from your windshield. Use the floor/defog mode to clear the windows of fog or moisture and warm the passengers. Use defrost to remove fog or frost from the windshield more quickly. - (Floor/Defog): Press the mode button until the defog mode appears on the display. This mode directs the air between the windshield, floor outlets and side windows. When you select this mode, the system turns off recirculation and runs the air-conditioning compressor unless the outside temperature is near or below freezing. The recirculation mode cannot be selected while in the floor/defog mode. 1 (Defrost): Press this button to direct most of the air to the windshield, with some air directed to the side windows. In this mode, the system will automatically turn off the recirculation and run the air-conditioning compressor, unless the outside temperature is near or below freezing. Recirculation cannot be selected while in the defrost mode. Do not drive the vehicle until all the windows are clear.


Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. The rear window defogger will only work when the engine is running. = (Rear Window Defogger): Press this button to turn the rear window defogger on or off. Be sure to clear as much snow from the rear window as possible. The rear window defogger will turn off approximately 10 minutes after the button is pressed when traveling less than 30 mph (48 km/h). If turned on again, the defogger will only run for approximately five minutes before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. The heated outside rearview mirrors will heat to help clear fog or frost from the surface of the mirrors when the rear window defogger is on. The rear window defogger and heated mirrors are automatically disabled when the retractable hardtop is moving or down. Notice: Don’t use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs wouldn’t be covered by your warranty. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid.


3-39


Outlet Adjustment Use the thumbwheel to open or close the outlets. Operation Tips • Clear away any ice, snow or leaves from the air


inlets at the base of the windshield that may block the flow of air into your vehicle.


• Use of non-GM approved hood deflectors may adversely affect the performance of the system. • Keep the area around the base of the instrument panel console and air path under the seats clear of objects to help circulate the air inside of your vehicle more effectively.


Passenger Compartment Air Filter The passenger compartment air filter removes certain odor and particles from the air including pollen and dust particles. Reductions in airflow, which may occur more often in dusty areas, indicate that the filter may need to be replaced early. The filter should be replaced as part of the routine scheduled maintenance. See ScheduledMaintenance on page6-4 for more information. The passenger compartment air filter is located on the passenger’s side of the engine compartment near the battery. See Engine Compartment Overview on page5-12 for more information on location. To check or replace the air filter, do the following: 1. With the hood open, unlatch and remove the


access panel.


2. Pull the old filter out of the housing. 3. Insert the new filter into the housing. The


filter should be fully inserted with the arrows pointing up.


4. Reinstall the air filter access panel.

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’re 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’s 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’re a big help. Your vehicle may also have a Driver Information Center that works along with the warning lights and gages. See DriverInformationCenter(DIC)onpage3-57.


3-41


Instrument Panel Cluster Your instrument panel cluster and Driver Information Center (DIC) are designed to let you know at a glance how the vehicle is running. You’ll know how fast you’re going, about how much fuel you have left and many other things you’ll need to know to drive safely and economically. The instrument panel cluster indicator warning lights, gages and DIC messages are explained on the following pages.


3-42


United States shown, Canada similar


Speedometer and Odometer Your speedometer lets you see your speed in either miles per hour (mph) or kilometers per hour (km/h). There is only one scale for mph and km/h. Use the Driver Information Center (DIC) controls to switch between mph and km/h. See DICControlsandDisplays onpage3-57 for more information. The cluster will calculate the proper speed and move the needle to the correct position. Either the MPH or the km/h telltale will illuminate, depending on which measurement you choose. The odometer is part of the Driver Information Center (DIC). See DICControlsandDisplayson page3-57 for more information.


Trip Odometer The trip odometer is part of the Driver Information Center (DIC). See DIC Controls and Displays on page3-57 for more information.


Tachometer The tachometer displays the engine speed in thousands of revolutions per minute (rpm). Fuel will shut off at about 6700 rpm. If you continue to drive your vehicle at the fuel shut off rpm, you could damage your engine. Be sure to operate your vehicle below the fuel shut off rpm or reduce your rpm quickly when the fuel shuts off.


Safety Belt Reminder Light When the engine is first turned on, 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 until the driver’s belt is buckled.


3-43


Air Bag Readiness Light There is an air bag readiness light on the instrument panel, which shows a deployed air bag symbol. The system checks the air bag’s electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the air bag modules, the wiring and the diagnostic module. For more information on the air bag system, see Air Bag Systems on page1-36.


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


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


{CAUTION:


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


The air bag readiness light should flash for a few seconds when you turn the vehicle on. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem.


3-44


Air Bag Off Light


When you turn the passenger’s air bags off, this light will come on and stay on to remind you that the air bags have been turned off. This light will go off when you turn the air bags back on. See AirBagOffSwitch onpage1-44 for more on this, including important safety information.


{CAUTION:


If the passenger’s air bags are turned off for a person who is not in a risk group identified by the national government, that person will not have the extra protection of the air bags. In a crash, the air bags would not be able to inflate and help protect the person sitting there. Do not turn off the passenger’s air bags unless the person sitting there is in a risk group. See AirBagOffSwitchonpage1-44 for more on this, including important safety information.


3-45


{CAUTION:


If the air bag readiness light ever comes on when you have turned off the air bags, it means that something may be wrong with the air bag system. The passenger’s air bags could inflate even though the switch is off. If this ever happens, do not let anyone whom the national government has identified as a member of a passenger air bag risk group sit in the passenger’s position (for example, do not secure a rear-facing child restraint in your vehicle) until you have your vehicle serviced. See AirBagOffSwitchonpage1-44.


Voltmeter Gage


When the vehicle is in accessory mode, the voltmeter shows the voltage output of your battery. When the engine is running, it shows the voltage output of the charging system.


The reading will change as the rate of charge changes (with engine speed, for example), but if the voltmeter reads at 9 volts or below, your instrument panel cluster and other systems may shut down. The Driver Information Center (DIC) will read LOW VOLTAGE when your vehicle is at 10 volts or below. Have it checked right away. Driving with the voltmeter reading at 10 volts or below could drain your battery and disable your vehicle.


3-46


Brake System Warning Light Your vehicle’s hydraulic brake system is divided into two parts. If one part isn’t working, the other part can still work and stop you. For good braking, though, you need both parts working well.


If the light comes on while you are driving and you have a LOW BRAKE FLUID message showing on the DIC, 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 page4-32.


{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.


United States


Canada


This light should come on when you start the engine. If it doesn’t come on then, have it fixed so it will be ready to warn you if there’s a problem. If this warning light stays on after you start the engine, the parking brake may still be set or there could be a brake problem. Refer to ParkingBrakeonpage2-26
to see if it is set. If the parking brake is not set, have your brake system inspected right away.


3-47


Anti-Lock Brake System Warning Light


Traction Control System (TCS) Warning Light


With the anti-lock brake system, the light will come on when your engine is started and may stay on for several seconds. That’s normal.


This light should come on briefly as you start the engine. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there’s a problem.


If the light stays on, turn the ignition off. Or, if the light comes on when you’re driving, stop as soon as possible and turn the ignition off. Then start the engine again to reset the system. If the light still stays on, or comes on again while you’re driving, your vehicle needs service. If the regular brake system warning light isn’t on, you still have brakes, but you don’t have anti-lock brakes. If the regular brake system warning light is also on, you don’t have anti-lock brakes and there’s a problem with your regular brakes. See “Service ABS” under DICWarningsandMessagesonpage3-59. The anti-lock brake system warning light will come on briefly when you turn the ignition on. This is normal. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem.


3-48


The light will also come on while the Stabilitrak® system warms up and the STABILITRAK WARMING message will be displayed in the Driver Information Center (DIC). If it stays on, or comes on and the DIC shows a SERVICE TRACTION SYS message when you’re driving, there’s a problem with your TCS and your vehicle needs service. When this light is on, the system will not limit wheel spin. Adjust your driving accordingly. If the driver turns off TCS by pressing the button on the console, the TCS system light will come on and the TRACTION SYSTEM-OFF message will show on the DIC.


If the light stays on or comes on while you are driving, a chime sounds and a SERVICE STABILITRAK message appears on the DIC, there is a problem with your Stabilitrak® and the vehicle needs service. You can acknowledge this message by pressing the RESET button. When the SERVICE STABILITRAK message is displayed, the Stabilitrak® system will not assist you in controlling the vehicle. You should have the system serviced as soon as possible. Adjust your driving accordingly. When the system is working, you will see the STABILITRAK ACTIVE message displayed in the DIC. You may also feel of hear the system working. This is normal. If you turn off the Stabilitrak® system by pressing the button on the console, the traction control system light will come on, a chime will sound and the TRAC/STABILITRAK OFF message will be displayed in the DIC. The Traction Control System will also be turned off. See DIC Warnings and Messages on page3-59 for more information. If the Stabilitrak® system and Traction Control System are turned off, pressing the console button momentarily will turn both systems on. The DIC will display the TRAC/STABILITRAK ON message, the instrument cluster light will be off and a chime will sound. See DIC WarningsandMessagesonpage3-59 for more information.


Engine Coolant Temperature Gage


United States


Canada


This gage shows the engine coolant temperature. As the pointer nears 260°F (125°C), your engine coolant temperature is high. A message may display on the Driver Information Center (DIC) depending on how high the temperature is. See DICWarningsandMessages on page3-59 for more information. See EngineOverheatingonpage5-23 for more information.


3-49


Tire Pressure Light


This light should come on briefly as you start the engine. It will then come on only when a low tire pressure condition exists.


See TirePressureMonitorSystemonpage5-58 for more information.


Malfunction Indicator Lamp Check Engine Light


Your vehicle is equipped with a computer which monitors operation of the fuel, ignition and emission control systems.


This system is called OBD II (On-Board Diagnostics-Second Generation) and is intended to assure 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 a problem and service is required. Malfunctions often will be indicated by the system before any problem is apparent. This may prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction.


3-50


Notice: If you keep driving your vehicle with this light on, after a while, your emission controls may not work as well, your fuel economy may not be as good and your engine may not run as smoothly. This could lead to costly repairs that may not be covered by your warranty. Notice: Modifications made to the engine, transmission, exhaust, intake or fuel system of your vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission controls and may cause this light to come on. Modifications to these systems could lead to costly repairs not covered by your warranty. This may also result in a failure to pass a required Emission Inspection/Maintenance test. This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If the light does not come on, have it repaired. This light will also come on during a malfunction in one of two ways: • Light Flashing — A misfire condition has been detected. A misfire increases vehicle emissions and may damage the emission control system on your vehicle. Diagnosis and service may be required.


• Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service may be required.


If the Light Is Flashing The following may prevent more serious damage to your vehicle: • Reducing vehicle speed. • Avoiding hard accelerations. • Avoiding steep uphill grades. 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, stopthevehicle. Find a safe place to park your vehicle. Turn the key 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 for service as soon as possible.


3-51


If the Light Is On Steady You also may 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 FillingYourTankonpage5-7. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow 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 electrical system may be wet. The condition will usually be 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 GasolineOctaneonpage5-4. Poor fuel quality will cause your engine not to run as efficiently as designed. You may 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 may 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 can check the vehicle. Your dealer has the proper test equipment and diagnostic tools to fix any mechanical or electrical problems that may have developed.


3-52


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


3-53


Engine Oil Pressure Gage


United States


Canada


The engine oil pressure gage shows the engine oil pressure in psi (pounds per square inch) or kPa (kilopascals) when the engine is running. Oil pressure should be 20 to 80 psi (140 to 550 kPa). In certain situations such as long, extended idles on hot days, it could read as low as 6 psi (40 kPa) and still be considered normal. It may vary with engine speed, outside temperature and oil viscosity. The Driver Information Center (DIC) may display messages regarding the oil condition. See DICWarningsand Messagesonpage3-59 and EngineOilonpage5-13.


3-54


{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. Security Light

Fuel Gage


Your fuel gage tells you about how much fuel you have left when the ignition is on.


When the needle approaches the low fuel symbol, LOW FUEL will appear on the Driver Information Center (DIC) display. At this time, you still have a little fuel left, but you should get more soon. Press RESET to acknowledge a DIC message(s). Pressing RESET will also turn off a DIC message but the LOW FUEL message will come on again in 10 minutes if you have not added fuel to the vehicle.


Here are five things that some owners ask about. All these things are normal and do not indicate that anything is wrong with the fuel gage. • At the gas station, the gas pump shuts off before


the gage reads the full symbol.


• It takes more (or less) fuel to fill up than the gage reads. For example, the gage reads half full, but it took more (or less) than half of the tank’s capacity to fit it.


• The gage pointer may move while cornering,


braking or speeding up.


• The gage may not indicate the tank is empty when


the ignition is turned off.


• The gage reading may change slightly within the


first several minutes after starting the vehicle.


3-56


You can use the Driver Information Center (DIC) to display more detailed fuel information. While scrolling through the DIC, you will also find: • AVERAGE XX.X MPG (Average Miles Per


Gallon): The fuel economy calculated for the last 20 gallons (76 L) of fuel used, or since you last reset the display.


• INST XX.X MPG (Instantaneous Miles Per


Gallon): The fuel economy calculated for your current driving conditions.


• RANGE XXX MI: The approximate distance you


can drive before refueling.

Trip Computer


Oil Life Indicator This feature lets you know when to change the engine oil. It’s based on the engine oil temperatures and your driving patterns. To see the display, press the information button several times until OIL LIFE appears. If you see 99% OIL LIFE, 99 percent of your current oil life remains. The DIC may display a CHANGE OIL NOW message. For more information, see ScheduledMaintenance onpage6-4. If you see CHANGE OIL NOW, it means the oil life is gone and you should change the oil right away. The system doesn’t check how much oil you have, so you’ll still have to check for that. To see how, see Engine Oil on page5-13. When the oil is changed, you’ll need to reset the system. See EngineOilonpage5-13. Always keep a written record of the mileage and date when you changed your oil.


Audio System(s) Notice: Before you add any sound equipment to your vehicle – like a tape player, CB radio, mobile telephone or two-way radio – be sure you can add what you want. If you can, it’s very important to do it properly. Added sound equipment may interfere with the operation of your vehicle’s engine, radio or other systems, and even damage them. Your vehicle’s systems may interfere with the operation of sound equipment that has been added improperly. So, before adding sound equipment, check with your dealer and be sure to check federal rules covering mobile radio and telephone units. Your audio system has been designed to operate easily and to give years of listening pleasure. You will get the most enjoyment out of it if you acquaint yourself with it first. Figure out which radio you have in your vehicle, find out what your audio system can do and how to operate all of its controls to be sure you’re getting the most out of the advanced engineering that went into it. Your vehicle has a feature called Retained Accessory Power (RAP). With RAP, you can play your audio system even after the ignition is turned off. See “Retained Accessory Power (RAP)” under Ignition Positions on page2-19.


3-72


Navigation/Radio System


Navigation/Radio Display and Controls


The display screen is located in the center of the instrument panel. There are “hard” buttons and a touch sensitive screen. Your vehicle is equipped with an AM-FM radio navigation system that includes digital signal processing (DSP), radio data system (RDS) with program type selections (PTY) that will seek out the kind of music you want to listen to. The radio system can also communicate with your navigation system to broadcast announcements on traffic, weather, and emergency alert communications. For information on how to use this system, see the “Navigation System” manual.


Radio Personalization with Home and Away Feature If DRIVER 1 (HOME or AWAY) PRESETS or DRIVER 2
(HOME or AWAY) PRESETS appears in the display when the radio is first turned on, your vehicle is equipped with this feature. This feature allows the driver to return to the last used audio source (radio, cassette, or CD) using the remote keyless entry transmitter. This feature can also store and recall AM and FM presets, volume, tone, and the last selected radio station. The number on the back of each transmitter (1 or 2) corresponds to driver 1 or 2. If transmitter 1 is used to enter the vehicle, the last used audio source and/or settings set by driver 1 will be recalled. If transmitter 2 is used to enter the vehicle, the last used audio source and/or settings set by driver 2 will be recalled. The settings can also be recalled by pressing the MEMORY seat buttons 1 or 2 located on the driver’s door. Your radio can store home and away presets. Home and away presets allow you to use one set of preset radio settings in the area where you live, and another set when you go out of town. You will not need to reprogram your presets every time you travel. With the radio off and the time displayed, use fast forward and reverse to select home or away presets.


3-73


To select the away presets, press and hold FF for five seconds until you hear a beep. The next time the radio comes on, the away presets will be active. To select the home presets, press and hold RW for five seconds until you hear a beep. The next time the radio comes on, the home presets will be active. When battery power is removed and later applied, you will not have to reset your home radio presets because the radio remembers them. However, you will have to reset your away radio presets.


Theft-Deterrent Feature THEFTLOCK® is designed to discourage theft of your radio. Your vehicle has a “built in” theft-deterrent feature on each radio that is automatic – there is no programming required. The radio in your vehicle cannot be used in any other vehicle. When the radio was originally installed in your vehicle at the factory, it stored the Vehicle Identification Number (VIN). Each time the ignition is turned on, the VIN is verified. If the vehicle’s VIN does not match the VIN stored in the radio, THEFTLOCK® will be activated and the audio system will not play. If the radio is removed from your vehicle, the original VIN in the radio can be used to trace the radio back to your vehicle.


3-74


Audio Steering Wheel Controls


Some audio controls can be adjusted at the steering wheel. They include the following:


g (Voice Recognition): See “OnStar® Steering Wheel Controls” under OnStar® Systemonpage2-35
for more information.


SRCE (Source): Press this button to switch between FM1, FM2, and AM, and XM1 and XM2 (48 contiguous US states, if equipped), and to switch between radio, CD, and DVD.


Understanding Radio Reception AM The range for most AM stations is greater than for FM, especially at night. The longer range, however, can cause stations to interfere with each other. AM can pick up noise from things like storms and power lines. Try reducing the treble to reduce this noise. FM Stereo FM stereo will give you the best sound, but FM signals will reach only about 10 to 40 miles (16 to 65 km). Tall buildings or hills can interfere with FM signals, causing the sound to come and go. XM™ Satellite Radio Service (48 Contiguous US States) XM™ Satellite Radio Service gives you digital radio reception from coast to coast. Just as with FM, tall buildings or hills can interfere with satellite radio signals, causing the sound to come and go. Your radio may display NO XM SIGNAL to indicate interference.


Cellular Phone Usage Cellular phone usage may cause interference with your vehicle’s radio. This interference may occur when making or receiving phone calls, charging the phone’s battery, or simply having the phone on. This interference is described as an increased level of static while listening to the radio. If you notice static while listening to the radio, unplug the cellular phone and turn it off.


Care of Your CDs Handle CDs carefully. Store them in their original cases or other protective cases and away from direct sunlight and dust. If the surface of a CD is soiled, dampen a clean, soft cloth in a mild, neutral detergent solution and clean it, wiping from the center to the edge. Be sure never to touch the side without writing when handling CDs. Pick up CDs by grasping the outer edges or the edge of the hole and the outer edge.


Care of Your CD Player The use of CD lens cleaners for CDs is not advised, due to the risk of contaminating the lens of the CD optics with lubricants internal to the CD mechanism.

Diversity Antenna System Your AM-FM antennas are located in the windshield and rear window. Be sure that the inside surfaces of the windshield and rear window are not scratched and that the lines on the glass are not damaged. If the inside surfaces are damaged, they could interfere with radio reception. Also, for proper radio reception, the antenna connector located on the passenger’s side top corner of the windshield and the antenna connector located on the driver’s side top corner of the rear window need to be properly attached to the buttons on the glass. Notice: Do not apply aftermarket glass tinting with metallic film. The metallic film in some tinting materials will interfere with or distort the incoming radio reception. Any damage caused to your backglass antenna due to metallic tinting materials will not be covered by your warranty.


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 pickup stations clearly. The repairs wouldn’t be covered by your warranty. If, when you turn on your rear window defogger, you hear static on your radio station, it could mean that a defogger grid line has been damaged. If this is true, the grid line must be repaired. If you choose to add an aftermarket cellular telephone to your vehicle, and the antenna needs to be attached to the glass, be sure that you do not damage the grid lines for the AM-FM antennas or place the cellular telephone antenna over the grid lines.


XM™ Satellite Radio Antenna System Your XM™ Satellite Radio antenna is located on the trunk of your vehicle. Keep this antenna clear of snow and ice build up for clear radio reception.

Your Driving, the Road, and Your Vehicle


Defensive Driving The best advice anyone can give about driving is: Drive defensively. Please start with a very important safety device in your vehicle: Buckle up. See SafetyBelts:TheyArefor Everyone on page1-4. Defensive driving really means “be ready for anything.” On city streets, rural roads or freeways, it means “always expect the unexpected.” Assume that pedestrians or other drivers are going to be careless and make mistakes. Anticipate what they might do. Be ready for their mistakes. Rear-end collisions are about the most preventable of accidents. Yet they are common. Allow enough following distance. It is the best defensive driving maneuver, in both city and rural driving. You never know when the vehicle in front of you is going to brake or turn suddenly. Defensive driving requires that a driver concentrate on the driving task. Anything that distracts from the driving task — such as concentrating on a cellular


telephone call, reading, or reaching for something on the floor — makes proper defensive driving more difficult and can even cause a collision, with resulting injury. Ask a passenger to help do things like this, or pull off the road in a safe place to do them yourself. These simple defensive driving techniques could save your life.


Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It is the number one contributor to the highway death toll, claiming thousands of victims every year. Alcohol affects four things that anyone needs to drive a vehicle: • Judgment • Muscular Coordination • Vision • Attentiveness. Police records show that almost half of all motor vehicle-related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving. In recent years, more than 16,000 annual motor vehicle-related deaths have been associated with the use of alcohol, with more than 300,000 people injured.


4-2


Many adults — by some estimates, nearly half the adult population — choose never to drink alcohol, so they never drive after drinking. For persons under 21, it is against the law in every U.S. state to drink alcohol. There are good medical, psychological and developmental reasons for these laws. The obvious way to eliminate the leading highway safety problem is for people never to drink alcohol and then drive. But what if people do? How much is “too much” if someone plans to drive? It is a lot less than many might think. Although it depends on each person and situation, here is some general information on the problem. The Blood Alcohol Concentration (BAC) of someone who is drinking depends upon four things: • The amount of alcohol consumed • The drinker’s body weight • The amount of food that is consumed before and


during drinking


• The length of time it has taken the drinker to


consume the alcohol.


According to the American Medical Association, a 180 lb (82 kg) person who drinks three 12 ounce (355 ml) bottles of beer in an hour will end up with a BAC of about 0.06 percent. The person would reach the


same BAC by drinking three 4 ounce (120 ml) glasses of wine or three mixed drinks if each had 1-1/2 ounces (45 ml) of liquors like whiskey, gin or vodka.


It is the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour, the person’s BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level.


4-3


There is a gender difference, too. Women generally have a lower relative percentage of body water than men. Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of her same body weight will when each has the same number of drinks. The law in an increasing number of U.S. states, and throughout Canada, sets the legal limit at 0.08 percent. In some other countries, the limit is even lower. For example, it is 0.05 percent in both France and Germany. The BAC limit for all commercial drivers in the United States is 0.04 percent. The BAC will be over 0.10 percent after three to six drinks (in one hour). Of course, as we have seen, it depends on how much alcohol is in the drinks, and how quickly the person drinks them.


But the ability to drive is affected well below a BAC of 0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and that the effects are worse at night. All drivers are impaired at BAC levels above 0.05 percent. Statistics show that the chance of being in a collision increases sharply for drivers who have a BAC of 0.05 percent or above. A driver with a BAC level of 0.06 percent has doubled his or her chance of having a collision. At a BAC level of 0.10 percent, the chance of this driver having a collision is 12 times greater; at a level of 0.15 percent, the chance is 25 times greater! The body takes about an hour to rid itself of the alcohol in one drink. No amount of coffee or number of cold showers will speed that up. “I will be careful” is not the right answer. What if there is an emergency, a need to take sudden action, as when a child darts into the street? A person with even a moderate BAC might not be able to react quickly enough to avoid the collision.


4-4


Control of a Vehicle You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering and the accelerator. All three systems have to do their work at the places where the tires meet the road. Sometimes, as when you are driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide. That means you can lose control of your vehicle. Also see TractionControl System(TCS)onpage4-9 and Stabilitrak® Systemon page4-11.


There is something else about drinking and driving that many people do not know. Medical research shows that alcohol in a person’s system can make crash injuries worse, especially injuries to the brain, spinal cord or heart. This means that when anyone who has been drinking — driver or passenger — is in a crash, that person’s chance of being killed or permanently disabled is higher than if the person had not been drinking.


{CAUTION:


Drinking and then driving is very dangerous. Your reflexes, perceptions, attentiveness and judgment can be affected by even a small amount of alcohol. You can have a serious — or even fatal — collision if you drive after drinking. Please do not drink and drive or ride with a driver who has been drinking. Ride home in a cab; or if you are with a group, designate a driver who will not drink.


4-5


Avoid needless heavy braking. Some people drive in spurts — heavy acceleration followed by heavy braking — rather than keeping pace with traffic. This is a mistake. Your brakes may not have time to cool between hard stops. Your brakes will wear out much faster if you do a lot of heavy braking. If you keep pace with the traffic and allow realistic following distances, you will eliminate a lot of unnecessary braking. That means better braking and longer brake life. If your engine ever stops while you are driving, brake normally but do not pump your brakes. If you do, the pedal may get harder to push down. If your engine stops, you will still have some power brake assist. But you will use it when you brake. Once the power assist is used up, it may take longer to stop and the brake pedal will be harder to push.


Braking Braking action involves perceptiontime and reactiontime. First, you have to decide to push on the brake pedal. That is perceptiontime. Then you have to bring up your foot and do it. That is reactiontime. Average reactiontime is about 3/4 of a second. But that is only an average. It might be less with one driver and as long as two or three seconds or more with another. Age, physical condition, alertness, coordination and eyesight all play a part. So do alcohol, drugs and frustration. But even in 3/4 of a second, a vehicle moving at 60 mph (100 km/h) travels 66 feet (20 m). That could be a lot of distance in an emergency, so keeping enough space between your vehicle and others is important. And, of course, actual stopping distances vary greatly with the surface of the road (whether it is pavement or gravel); the condition of the road (wet, dry, icy); tire tread; the condition of your brakes; the weight of the vehicle and the amount of brake force applied.


4-6


Anti-lock Brake System (ABS) Your vehicle has anti-lock brakes. ABS is an advanced electronic braking system that will help prevent a braking skid. When you start your engine and begin to drive away, your anti-lock brake system will check itself. You may hear a momentary motor or clicking noise while this test is going on, and you may even notice that your brake pedal moves a little. This is normal.


If there is a problem with the anti-lock brake system, this warning light will stay on. See Anti-Lock BrakeSystemWarning Lightonpage3-48.


Let us say the road is wet and you are driving safely. Suddenly, an animal jumps out in front of you. You slam on the brakes and continue braking. Here is what happens with ABS: A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each wheel.


4-7


The anti-lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard.


Remember: Anti-lock does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you will not have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti-lock brakes. Using Anti-Lock Do not pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you. You may hear a motor or clicking noise and feel the brake pedal move a little during a stop, but this is normal. Braking in Emergencies With anti-lock, you can steer and brake at the same time. In many emergencies, steering can help you more than even the very best braking.


As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly.


4-8


Traction Control System (TCS) Your vehicle has a traction control system that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that one or both of the rear wheels are spinning or beginning to lose traction. When this happens, the system works the rear brakes and reduces engine power to limit wheel spin. The TRAC SYSTEM ACTIVE message will display on the Driver Information Center (DIC) when the traction control system is limiting wheel spin. See DICWarnings andMessagesonpage3-59. You may feel or hear the system working, but this is normal. If your vehicle is in cruise control when the traction control system begins to limit wheel spin, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may reengage the cruise control. See “Cruise Control” under Turn Signal/Multifunction Lever on page3-7.


This warning light will come on to let you know if there’s a problem with your traction control system.


See TractionControlSystem(TCS)WarningLighton page3-48. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. The traction control system automatically comes on whenever you start your vehicle. To limit wheel spin, especially in slippery road conditions, you should always leave the system on. But you can turn the traction control system off if you ever need to. You should turn the system off if your vehicle ever gets stuck in sand, mud or snow and rocking the vehicle is required. See “Rocking Your Vehicle To Get It Out” under IfYouAreStuck:InSand,Mud,IceorSnowon page4-31.


4-9


Magnetic Ride Control Magnetic Ride Control automatically adjusts the ride of your vehicle. Automatic ride control is achieved through a computer used to control and monitor the suspension system. The controller receives input from various sensors to determine the proper system response. If the controller detects a problem within the system, the DIC will display a SERVICE RIDE CONTROL message. See DICWarningsandMessages onpage3-59 for more information. See your dealer for service.


Limited-Slip Rear Axle Your limited-slip rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, this feature will allow the wheel with traction to move the vehicle.


To turn the system off, press the traction control button located on the center console.


The TRACTION SYSTEM-OFF message will display on the DIC and the traction control system warning light will come on. If the system is limiting wheel spin when you press the button, the TRACTION SYSTEM-OFF message will display – but the system won’t turn off right away. It will wait until there’s no longer a current need to limit wheel spin. You can turn the system back on at any time by pressing the button again. The TRACTION SYSTEM-ON message should display briefly on the Driver Information Center.


4-10


Stabilitrak® System The Stabilitrak® System is a computer controlled system that helps the driver maintain directional control of the vehicle in difficult driving conditions. This is accomplished by selectively applying any one of the vehicle’s brakes. When you first start your vehicle and begin to drive away (6 mph (10 km/h)), especially during cold weather, the message STABILITRAK WARMING may be displayed in the Driver Information Center (DIC), the instrument cluster light will be on, and a chime will sound. This is normal. You can acknowledge this message by pressing the RESET button. The Stabilitrak® System performance is affected until the message, STABILITRAK READY, is displayed in the DIC. The WAIT FOR STABILITRAK message may be displayed in the DIC after exceeding 19 mph (30 km/h) for 10 seconds if the steering is not centered. The system is off until the STABILITRAK ACTIVE message is displayed. The STABILITRAK ACTIVE message will come on when the system is operating. See DICWarningsand Messagesonpage3-59 for more information. You may also feel or hear the system working. This is normal.


The instrument cluster light will come on and a chime will sound to let you know if there is a problem with the system.


The SERVICE STABILITRAK message will also be displayed. See DICWarningsandMessageson page3-59 for more information. When this light and the SERVICE STABILITRAK message are on, the system is not operational. Adjust your driving accordingly. The system comes on automatically whenever you start your vehicle. To help maintain directional control of the vehicle, you should always leave the system on. You can turn the system off if you ever need to. If you turn the STABILITRAK® System off, the Traction Control System will also be turned off. Adjust your driving accordingly.


4-11


To turn the system off, press and hold the traction control button on the console for five seconds with the vehicle stopped. You can turn the system back on at any time by pressing the button.


The DIC will display the appropriate message when you push the button, either TRAC/STABILITRAK ON or TRAC/STABILITRAK OFF.


Steering Power Steering If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort. Magnetic Speed Variable Assist Steering Your vehicle is equipped with a steering system that continuously adjusts the effort you feel when steering at all vehicle speeds. It provides ease when parking, yet a firm, solid feel at highway speeds.
