Driving and Operating


This is the only position from which the key can be removed. If the key cannot be removed, make sure the shift lever is in P (Park). The ignition switch can bind in the LOCK/OFF position with the wheels turned off center. If this happens, move the steering wheel from right to left while turning the key to ACC/ ACCESSORY. If this does not work, then the vehicle needs service. Do not turn the engine off when the vehicle is moving. This will cause a loss of power assist in the brake and steering systems and disable the airbags. If the vehicle must be shut off in an emergency: 1. Brake using a firm and steady


pressure. Do not pump the brakes repeatedly. This may deplete power assist, requiring increased brake pedal force.


2. Shift the vehicle to N (Neutral).


This can be done while the vehicle is moving. After shifting


to N (Neutral), firmly apply the brakes and steer the vehicle to a safe location.


3. Come to a complete stop, shift to P (Park), and turn the ignition to LOCK/OFF. On vehicles with an automatic transmission, the shift lever must be in P (Park) to turn the ignition switch to the LOCK/OFF position.


4. Set the parking brake. See


Parking Brake on page 9-31.


{ Warning


Turning off the vehicle while moving may cause loss of power assist in the brake and steering systems and disable the airbags. While driving, only shut the vehicle off in an emergency.


If the vehicle cannot be pulled over, and must be shut off while driving, turn the ignition to ACC/ ACCESSORY.


2 (ACC/ACCESSORY): This position provides power to some of the electrical accessories. It unlocks the steering wheel and ignition. To move the key from ACC/ ACCESSORY to LOCK/OFF, push in the key and then turn it to LOCK/OFF. 3 (ON/RUN): The ignition switch stays in this position when the engine is running. This position can be used to operate the electrical accessories, including the ventilation fan and 12-volt power outlets, as well as to display some warning and indicator lights. This position can also be used for service and diagnostics, and to verify the proper operation of the malfunction indicator lamp as may be required for emission inspection purposes. The transmission is also unlocked in this position on automatic transmission vehicles. The battery could be drained if the key is left in the ACC/ACCESSORY or ON/RUN position with the engine

{ Caution


{ Caution


Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped.


{ Caution


If you add electrical parts or accessories, you could change the way the engine operates. Any resulting damage would not be covered by the vehicle warranty. See Add-On Electrical Equipment on page 9-57.


If the steering wheel is turned until it reaches the end of its travel, and is held in that position while starting the vehicle, damage may occur to the hydraulic power steering system and there may be loss of power steering assist.


Starting Procedure 1. With your foot off the accelerator


pedal, turn the ignition key to START. When the engine starts, let go of the key. The idle speed will go down as the engine warms. Do not race the engine immediately after starting it. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts.

Driving and Operating


{ Caution


Cranking the engine for long periods of time, by returning the ignition to the START position immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down.


2.


If the engine does not start after five to 10 seconds, especially in very cold weather (below −18°C or 0°F), it could be flooded with too much gasoline. Push the accelerator pedal all the way to the floor and hold it there as you hold the key in START for a maximum of 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool. When the engine starts, let go of the key and accelerator. If the vehicle starts briefly but then stops again, repeat the


procedure. This clears the extra gasoline from the engine. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts.


Retained Accessory Power (RAP) These vehicle accessories can be used for up to 10 minutes after the engine is turned off: . Audio System . Power Windows . Sunroof (if equipped) Power to the audio system will continue to operate for up to 10 minutes or until the driver door is opened. Power to the power windows and sunroof will continue to operate for up to 10 minutes or until any door is opened.


All these features will work when the key is in ON/RUN or ACC/ ACCESSORY.


Engine Coolant Heater The engine coolant heater, if available, can help in cold weather conditions at or below −18°C (0°F) for easier starting and better fuel economy during engine warm-up. Plug in the coolant heater at least four hours before starting the vehicle. An internal thermostat in the plug-end of the cord will prevent engine coolant heater operation at temperatures above −18°C (0°F).

Drive Systems


Brakes


All-Wheel Drive Vehicles with this feature transfer engine power, as required, to all four wheels. It is fully automatic, and adjusts itself as needed for road conditions. When using a compact spare tire on an AWD vehicle, the system automatically detects the compact spare and reduces AWD performance to protect the system. To restore full AWD operation and prevent excessive wear on the system, replace the compact spare with a full-size tire as soon as possible. See Compact Spare Tire on page 10-65.


Antilock Brake System (ABS) This vehicle has ABS, an advanced electronic braking system that helps prevent a braking skid. When the vehicle begins to drive away, ABS checks itself. A momentary motor or clicking noise might be heard while this test is going on, and it might even be noticed that the brake pedal moves a little. This is normal.


If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 5-15.


If driving safely on a wet road and it becomes necessary to slam on the brakes and continue braking to avoid a sudden obstacle, a computer senses the wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each wheel. ABS can change the brake pressure to each wheel, as required, faster than any driver could. This can help you steer around the obstacle while braking hard. As the brakes are applied, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS does not change the time needed to get a foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, there will not be enough time to apply the brakes if that vehicle

suddenly slows or stops. Always leave enough room up ahead to stop, even with ABS. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let ABS work. You may hear the ABS pump or motor operating and feel the brake pedal pulsate. This is normal. Braking in Emergencies ABS allows you to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking.


Parking Brake


To set the parking brake, hold the regular brake pedal down, then push the parking brake pedal down. If the ignition is on, the brake system warning light will come on. See Brake System Warning Light on page 5-14.


{ Caution


Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Make sure that the parking brake is fully released and the brake warning light is off before driving.


To release the parking brake, hold the regular brake pedal down, then push down momentarily on the parking brake pedal until you feel the pedal release. Slowly pull your foot up off the parking brake pedal. If the parking brake is not released when you begin to drive, the brake system warning light will be on and a chime will sound warning you that the parking brake is still on. If you are towing a trailer and are parking on a hill, see Driving Characteristics and Towing Tips on page 9-51.

Driving and Operating


Brake Assist The Brake Assist feature is designed to assist the driver in stopping or decreasing vehicle speed in emergency driving conditions. This feature uses the stability system hydraulic brake control module to supplement the power brake system under conditions where the driver has quickly and forcefully applied the brake pedal in an attempt to quickly stop or slow down the vehicle. The stability system hydraulic brake control module increases brake pressure at each corner of the vehicle until the ABS activates. Minor brake pedal pulsation or pedal movement during this time is normal and the driver should continue to apply the brake pedal as the driving situation dictates. The Brake Assist feature will automatically disengage when the brake pedal is released or brake pedal pressure is quickly decreased.


Hill Start Assist (HSA) This vehicle has an HSA feature, which may be useful when the vehicle is stopped on a grade sufficient enough to activate HSA. This feature is designed to prevent the vehicle from rolling, either forward or rearward, during vehicle drive off. After the driver completely stops and holds the vehicle in a complete standstill on a grade, HSA will be automatically activated. During the transition period between when the driver releases the brake pedal and starts to accelerate to drive off on a grade, HSA holds the braking pressure for a maximum of two seconds to ensure that there is no rolling. The brakes will automatically release when the accelerator pedal is applied within the two-second window. It will not activate if the vehicle is in a drive gear and facing downhill, or if the vehicle is facing uphill and in R (Reverse).


Ride Control Systems


Traction Control/ Electronic Stability Control


System Operation The vehicle has a Traction Control System (TCS) and StabiliTrak®, an electronic stability control system. These systems help limit wheel slip and assist the driver in maintaining control, especially on slippery road conditions. TCS activates if it senses that any of the drive wheels are spinning or beginning to lose traction. When this happens, TCS applies the brakes to the spinning wheels and reduces engine power to limit wheel spin. StabiliTrak activates when the vehicle senses a difference between the intended path and the direction the vehicle is actually traveling. StabiliTrak selectively applies braking pressure to any one of the

vehicle wheel brakes to assist the driver in keeping the vehicle on the intended path. If cruise control is being used and traction control or StabiliTrak begins to limit wheel spin, cruise control will disengage. Cruise control may be turned back on when road conditions allow. Both systems come on automatically when the vehicle is started and begins to move. The systems may be heard or felt while they are operating or while performing diagnostic checks. This is normal and does not mean there is a problem with the vehicle. It is recommended to leave both systems on for normal driving conditions, but it may be necessary to turn TCS off if the vehicle gets stuck in sand, mud, ice, or snow. See If the Vehicle Is Stuck on page 9-13 and “Turning the Systems Off and On” later in this section.


The indicator light for both systems is in the instrument cluster. This light will:


Flash when TCS is limiting wheel spin. Flash when StabiliTrak is activated. Turn on and stay on when either system is not working.


If either system fails to turn on or to activate, a message displays in the Driver Information Center (DIC), and d comes on and stays on to indicate that the system is inactive and is not assisting the driver in maintaining control. The vehicle is safe to drive, but driving should be adjusted accordingly.


If d comes on and stays on: 1. Stop the vehicle. 2. Turn the engine off and wait


15 seconds.


3. Start the engine. Drive the vehicle. If d comes on and stays on, the vehicle may need more time to diagnose the problem. If the condition persists, see your dealer. Turning the Systems Off and On

Cruise Control With cruise control, the vehicle can maintain a speed of about 40 km/h (25 mph) or more without keeping your foot on the accelerator. Cruise control does not work at speeds below 40 km/h (25 mph). { Warning


Cruise control can be dangerous where you cannot drive safely at a steady speed. Do not use cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads.


If equipped with the StabiliTrak® system, the system may begin to limit wheel spin while you are using cruise control. If this happens, the

Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase the vehicle speed. When you take your foot off the pedal, the vehicle slows down to the previously set cruise control speed. While pressing the accelerator pedal or shortly following the release to override cruise control, briefly moving the thumbwheel toward SET/− will result in cruise set to the current vehicle speed.


Using Cruise Control on Hills How well the cruise control works on hills depends upon the vehicle speed, load, and the steepness of the hills. When going up steep hills, you might have to step on the accelerator pedal to maintain the vehicle speed. When going downhill, you might have to brake or shift to a lower gear to maintain the vehicle speed. When the brakes are applied, the cruise control is disengaged.

Erasing Speed Memory The cruise control set speed is erased from memory if o is pressed or if the vehicle is turned off.


Driver Assistance Systems


Forward Collision Alert (FCA) System If equipped, the FCA system may help to avoid or reduce the harm caused by front-end crashes. When approaching a vehicle ahead too quickly, FCA provides a red flashing alert and rapidly beeps. FCA also lights a red visual alert if following another vehicle much too closely. FCA detects vehicles within a distance of approximately 60 m (197 ft) and operates at speeds above 40 km/h (25 mph). { Warning


FCA is a warning system and does not apply the brakes. When approaching a slower-moving or stopped vehicle ahead too rapidly, (Continued)

or when following a vehicle too closely, FCA may not provide a warning with enough time to help avoid a crash. FCA does not warn of pedestrians, animals, signs, guardrails, bridges, construction barrels, or other objects. Be ready to take action and apply the brakes. For more information, see Defensive Driving on page 9-3.


FCA can be disabled with the FCA steering wheel control. Detecting the Vehicle Ahead


FCA warnings will not occur unless the FCA system detects a vehicle ahead. When a vehicle is detected,

Driving and Operating


the vehicle-ahead indicator will display green. Vehicles may not be detected on curves, highway exit ramps, or hills; or due to poor visibility. FCA will not detect another vehicle ahead until it is completely in the driving lane.


{ Warning


FCA does not provide a warning to help avoid a crash, unless it detects a vehicle. FCA may not detect a vehicle ahead if the FCA sensor is blocked by dirt, snow, or ice, or if the windshield is damaged. It may also not detect a vehicle on winding or hilly roads, or in conditions that can limit visibility such as fog, rain, or snow, or if the headlamps or windshield are not cleaned or in proper condition. Keep the windshield, headlamps, and FCA sensors clean and in good repair.


Collision Alert


Selecting the Alert Timing


When your vehicle approaches another detected vehicle too rapidly, the red FCA display will flash and sound several high-pitched beeps from the front. When this Collision Alert occurs, the brake system may prepare for driver braking to occur more rapidly which can cause a brief, mild deceleration. Continue to apply the brake pedal as needed. Cruise control may be disengaged when the Collision Alert occurs.


Tailgating Alert The red Collision Alert display will stay continuously illuminated when following a detected vehicle ahead much too closely.


The Collision Alert control is on the steering wheel. Press COLLISION ALERT to set the FCA timing to far, medium, near, or off. The first button press shows the current control setting on the DIC. Additional button presses will change this setting. The chosen setting will remain until it is changed and will affect both the Collision Alert and the Tailgating Alert features. The timing of both alerts will vary based on vehicle speed. The faster the vehicle speed, the farther away the alert will occur.

Consider traffic and weather conditions when selecting the alert timing. The range of selectable alert timing may not be appropriate for all drivers and driving conditions. Unnecessary Alerts FCA may provide unnecessary alerts for turning vehicles, vehicles in other lanes, objects that are not vehicles, or shadows. These alerts are normal operation and the vehicle does not need service. Cleaning the System If the FCA system does not seem to operate properly, cleaning the outside of the windshield in front of the rearview mirror may correct the issue.


Parking Assist For vehicles with the Rear Parking Assist (RPA) system, it assists the driver with parking and avoiding objects while in R (Reverse). RPA operates at speeds less than 8 km/h (5 mph), and the sensors on the rear


bumper detect objects up to 2.5 m (8 ft) behind the vehicle, and at least 20 cm (8 in) off the ground. The distance objects can be detected may be less during warmer or humid weather.


{ Warning


The parking assist system does not detect children, pedestrians, bicyclists, animals, or objects below the bumper or that are too close or too far from the vehicle. It is not available at speeds greater than 8 km/h (5 mph). To prevent injury, death, or vehicle damage, even with parking assist, always check the area around the vehicle and check all mirrors before backing.


How the System Works RPA comes on automatically when the shift lever is moved into R (Reverse). A single beep sounds to indicate the system is working.


RPA operates only at speeds less than 8 km/h (5 mph). A detected obstacle is indicated by audible beeps. The interval between the beeps becomes shorter as the vehicle gets closer to the obstacle. When the distance is less than 30 cm (12 in) the beeping is continuous for five seconds. Turning the System On and Off The RPA system can be turned on and off using the infotainment system controls. See Vehicle Personalization on page 5-31 for more information. The On with Tow Bar Attached setting allows for the parking assist to work properly with a small item attached to the trailer hitch. When the system is off, PARK ASSIST OFF displays on the Driver Information Center (DIC). The message disappears after a short period of time. RPA defaults to the on setting each time the vehicle is started.

Turn RPA off when towing a trailer. When the System Does Not Seem to Work Properly The following messages may be displayed on the DIC: SERVICE PARKING ASSIST: If this message occurs, check the following conditions:


The sensors are not clean. Keep the vehicle's rear bumper free of mud, dirt, snow, ice, and slush. For cleaning instructions, see Exterior Care on page 10-73. The park assist sensors are covered by frost or ice. Frost or ice can form around and behind the sensors and may not always be seen; this can occur after washing the vehicle in cold weather. The message may not clear until the frost or ice has melted.


If the above conditions do not exist, take the vehicle to your dealer to repair the system.


If the RPA


PARK ASSIST OFF: system does not activate due to a temporary condition, the message displays on the DIC. This can occur under the following conditions: The driver has disabled the system.


. A trailer was attached to the


vehicle, or an object was hanging out of the liftgate during the last drive cycle. Once the object is removed, RPA will return to normal operation. . A tow bar is attached to the


vehicle. The bumper is damaged. Take the vehicle to your dealer to repair the system.


. Other conditions, such as


vibrations from a jackhammer or the compression of air brakes on a very large truck, are affecting system performance.


Side Blind Zone Alert (SBZA) If equipped, the SBZA system is a lane-changing aid that assists drivers with avoiding crashes that occur with vehicles in the side blind zone (or spot) areas. The SBZA warning display will light up in the corresponding outside side mirror and will flash if the turn signal is on.


{ Warning


SBZA does not alert the driver to vehicles rapidly approaching outside of the side blind zones, pedestrians, bicyclists, or animals. It may not provide alerts when changing lanes under all driving conditions. Failure to use proper care when changing lanes may result in injury, death, or vehicle damage.

If the DIC still displays the system unavailable message after cleaning both sides of the vehicle toward the rear corners of the vehicle, see your dealer.


If the SBZA displays do not light up when vehicles are in the blind zone and the system is clean, the system may need service. Take the vehicle to your dealer. When SBZA is disabled for any reason other than the driver turning it off, the Side Blind Zone Alert On option will not be available on the personalization menu. Radio Frequency Information See Radio Frequency Statement on page 13-12.


Rear Vision Camera (RVC) If equipped, the RVC can assist the driver when backing up by displaying a view of the area behind the vehicle.


{ Warning


The RVC system does not display children, pedestrians, bicyclists, crossing traffic, animals, or any other object located outside the camera's field of view, below the bumper, or under the vehicle. Perceived distances may be different from actual distances. Do not back the vehicle using only the RVC screen. Failure to use proper care before backing may result in injury, death, or vehicle damage. Always check behind and around the vehicle before backing.

Lane Departure Warning (LDW) If equipped, LDW may help avoid crashes due to unintentional lane departures. It may provide an alert if the vehicle is crossing a lane without using a turn signal in that direction. LDW uses a camera sensor to detect the lane markings at speeds of 56 km/h (35 mph) or greater.


{ Warning


The LDW system does not steer the vehicle. The LDW system may not:


. Provide enough time to avoid


a crash.


. Detect lane markings under


poor weather or visibility conditions. This can occur if the windshield or headlamps are blocked by dirt, snow, or ice; if they are not in

. Detect road edges. . Detect lanes on winding or


hilly roads.


If LDW only detects lane markings on one side of the road, it will only warn you when departing the lane on the side where it has detected a lane marking. Always keep your attention on the road and maintain proper vehicle position within the lane, or vehicle damage, injury, or death could occur. Always keep the windshield, headlamps, and camera sensors clean and in good repair. Do not use LDW in bad weather conditions.

If the LDW system is not functioning properly when lane markings are clearly visible, cleaning the windshield may help. LDW alerts may occur due to tar marks, shadows, cracks in the road, temporary or construction lane markings, or other road imperfections. This is normal system operation; the vehicle does not need service. Turn LDW off if these conditions continue.


Fuel Use of the recommended fuel is an important part of the proper maintenance of this vehicle. When driving in the U.S. and Canada, to help keep the engine clean and maintain optimum vehicle performance, we recommend using TOP TIER Detergent Gasolines. See www.toptiergas.com for a list of TOP TIER Detergent Gasolines.


When LDW is on, @ is green if LDW is available to warn of a lane departure. If the vehicle crosses a detected lane marking without using the turn signal in that direction, @ changes to amber and flashes. Additionally, there will be three beeps on the right or left, depending on the lane departure direction. When the System Does Not Seem To Work Properly The system may not detect lanes as well when there are: . Close vehicles ahead. . Sudden lighting changes, such


as when driving through tunnels.


. Banked roads.

If the vehicle has a yellow fuel cap, E85 or FlexFuel can be used in the vehicle. See E85 or FlexFuel on page 9-48. Use regular unleaded gasoline meeting ASTM specification D4814
with a posted octane rating of 87 or higher. Do not use gasoline with an octane rating below 87, as it may cause engine damage and will lower fuel economy.


Use of Seasonal Fuels Use summer and winter fuels in the appropriate season. The fuels industry automatically modifies the fuel for the appropriate season. If fuel is left in the vehicle tank for long periods of time, driving or starting could be affected. Drive the vehicle until the fuel is at one-half tank or less, then refuel with the current seasonal fuel.


Prohibited Fuels Gasolines containing oxygenates such as ethers and ethanol, as well as reformulated gasolines, are


available in some cities. If these gasolines comply with the previously described specification, then they are acceptable to use. However, E85 (85% ethanol) and other fuels containing more than 15% ethanol must be used only in FlexFuel vehicles.


{ Caution


Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under the vehicle warranty.


Some gasolines, mainly high octane racing gasolines, can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). Do not use gasolines and/or fuel additives with MMT as they can reduce spark plug life and affect emission control system performance. The


malfunction indicator lamp may turn on. If this occurs, see your dealer for service.


California Fuel Requirements If the vehicle is certified to meet California Emissions Standards, it is designed to operate on fuels that meet California specifications. See the underhood emission control label. If this fuel is not available in states adopting California Emissions Standards, the vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance might be affected. The malfunction indicator lamp could turn on and the vehicle may not pass a smog-check test. See Malfunction Indicator Lamp on page 5-12. If this occurs, return to your authorized dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by the vehicle warranty.

Fuels in Foreign Countries If planning to drive in countries outside the U.S. or Canada, the proper fuel might be hard to find. Check regional auto club or fuel retail brand websites for availability in the country where driving. Never use leaded gasoline, fuel containing methanol, manganese, or any other fuel not recommended. Costly repairs caused by use of improper fuel would not be covered by the vehicle warranty.


Fuel Additives To keep fuel systems clean, TOP TIER Detergent Gasoline is recommended. See Fuel on page 9-46. If TOP TIER Detergent Gasoline is not available, one bottle of Fuel System Treatment PLUS added to the fuel tank at every engine oil change can help. Fuel System Treatment PLUS is the only


gasoline additive recommended by General Motors. It is available at your dealer. Do not use additives with E85 or FlexFuel.


E85 or FlexFuel Vehicles with fuel caps marked as “E85” or FlexFuel can use either unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85). All other vehicles should use only the unleaded gasoline as described in Fuel on page 9-46. The use of E85 or FlexFuel is encouraged when the vehicle is designed to use it. E85 or FlexFuel is made from renewable sources. Many fuel stations will not have an 85% ethanol fuel (E85) pump available. Those stations that do have E85 should have a label indicating the FlexFuel ethanol content. Do not use the fuel if the ethanol content is greater than 85%.


The starting characteristics of E85
or FlexFuel make it unsuitable for use when temperatures fall below -18°C (0°F). Use gasoline or add gasoline to the E85 or FlexFuel. Because E85 or FlexFuel has less energy per liter (gallon) than gasoline, the vehicle will need to be refilled more often. See Filling the Tank on page 9-49.


{ Caution Some additives are not compatible with E85 or FlexFuel and can harm the vehicle's fuel system. Do not add anything to E85 or FlexFuel. Damage caused by additives would not be covered by the vehicle warranty.
