Cleaning the Sensing System The camera sensor on the back of the rearview mirror and the radar sensors on the front of the vehicle can become blocked by snow, ice, dirt, or mud. These areas need to be cleaned for ACC to operate properly. For cleaning instructions, see “Washing the Vehicle” under Exterior Care on page 10-77. System operation may also be limited under snow, heavy rain, or road spray conditions.
Do not use ACC when driving on steep hills or when towing a trailer. ACC will not detect a vehicle in the lane while driving on steep hills. The driver will often need to take over acceleration and braking on steep hills, especially when towing a trailer. If the brakes are applied, the ACC disengages.
Ending ACC There are three ways to disengage ACC: . Step lightly on the brake pedal. . Press *.
. Press ].
Erasing Speed Memory The cruise control set speed is erased from memory if ] is pressed or if the ignition is turned off.

Audible or Safety Alert Seat Some driver assistance features alert the driver of obstacles by beeping. To change the volume of the warning chime, see “Comfort and Convenience” under Vehicle Personalization on page 5-43. If equipped with the Safety Alert Seat, the driver seat cushion may provide a vibrating pulse alert instead of beeping. To change this, see “Collision/Detection Systems” under Vehicle Personalization on page 5-43.
Assistance Systems for Parking or Backing When the vehicle is in R (Reverse), the Rear Vision Camera (RVC) and Ultrasonic Rear Parking Assist (URPA) may help the driver to avoid a crash or to reduce crash damage while parking or backing. Some models may also have the Rear Automatic Braking and Backing
Warning System, Rear Cross Traffic Alert (RCTA), and/or Front Parking Assist. When the vehicle is shifted into R (Reverse), the RVC displays an image of the area behind the vehicle in the center stack display. When the vehicle is shifted out of R (Reverse), the screen returns to the previous content, after a short delay. To see the previous content sooner, press one of the radio buttons. If the message Service Rear Camera System is displayed, the vehicle may need service.

When an object is detected, either three beeps sound from the left or right side or three Safety Alert Seat pulses occur on the left or right side, depending on the direction of the detected vehicle. Use caution while backing up when towing a trailer, as the RCTA detection zones that extend out from the back of the vehicle do not move further back when a trailer is towed. URPA, and if equipped, also Front Park Assist, operates at speeds of less than 8 km/h (5 mph) and detects nearby objects within a zone 25 cm (10 in) high off the ground and below bumper level. The sensors on the rear bumper detect objects up to 2.5 m (8 ft) behind the vehicle. If the vehicle has the Front Parking Assist, it also detects objects 1.2 m (4 ft) in front of the

{ Warning
The parking assist system does not detect children, pedestrians, bicyclists, animals, or objects located 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 moving forward or backing.
Safety Alert Seat will pulse five times. Beeps for Front Parking Assist are higher pitched than for Rear Parking Assist. Vehicles with Adaptive Cruise Control (ACC) have the Backing Warning System, which is designed to help avoid backing crashes. The system can warn of rear objects when backing up at speeds greater than 8 km/h (5 mph). The Backing Warning System will beep once from the rear when a potential object threat is first detected, or pulse twice on both sides of the Safety Alert Seat. When the system detects a potential imminent crash, beeps will be heard from the rear, or five pulses will be felt on both sides of the Safety Alert Seat. There may also be a brief, sharp application of the brakes.
The vehicle may have an instrument cluster parking assist display with bars that show “distance to object” and object location information for URPA, and on some vehicles, for the Front Parking Assist system. As the object gets closer, more bars light up and the bars change color from yellow to amber to red. When an object is first detected in the rear, one beep will be heard from the rear, or both sides of the Safety Alert Seat will pulse two times. When an object is very close (<0.6 m (2 ft) in the vehicle rear, or <0.3 m (1 ft) in the vehicle front), five beeps will sound from the rear or front depending where the object is detected, or both sides of the

Driving and Operating
{ Warning
The Backing Warning System only operates at speeds greater than 8 km/h (5 mph). It does not detect children, pedestrians, bicyclists, animals, or objects below the bumper or that are too close or too far from the vehicle. In some situations, such as at higher backing speeds, there may not be enough time for the short, sharp application of the vehicle brake system to occur. To prevent injury, death, or vehicle damage, even with the Backing Warning System, always check the area around the vehicle and check all mirrors before backing.
Vehicles with Adaptive Cruise Control (ACC) also have the Rear Automatic Braking system, which is designed to help avoid or reduce the harm caused by backing crashes. If the system detects the
vehicle is backing too fast to avoid a crash with a detected object, it may automatically brake hard to a stop.
{ Warning
Rear Automatic Braking may not avoid many types of backing crashes. Do not wait for the automatic braking to apply. This system is not designed to replace driver braking, but only acts when the vehicle may not stop in time. The system, in some situations or environments, may not brake or may not brake in time to avoid a crash. It does not detect children, pedestrians, bicyclists, animals, or objects below the bumper or that are too close or too far from the vehicle. To prevent injury, death, or vehicle damage, even with Rear Automatic Braking, always check the area around the vehicle before and while backing.
Pressing the brake pedal after the vehicle comes to a stop will release the Rear Automatic Braking. If the brake pedal is not pressed within two seconds after the stop, the electric parking brake is set. Release the electric parking brake. When it is safe, pressing the accelerator pedal firmly at any time will override the Rear Automatic Braking.
{ Warning
There may be instances where unexpected or undesired automatic braking occurs. If this happens, either press the brake pedal or firmly press the accelerator pedal to release the brakes from the Rear Automatic Braking system. Before releasing the brakes, check the RVC screen and check the area around the vehicle to make sure it is safe to proceed.

Emergency Braking System can help to avoid a crash or reduce crash damage.
Forward Collision Alert (FCA) System If equipped, the FCA system may help to avoid or reduce the harm caused by front-end crashes. FCA provides a flashing red alert on the windshield, and rapidly beeps or pulses the Safety Alert Seat when approaching a vehicle directly ahead too quickly. FCA also lights an amber 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). If the vehicle has Adaptive Cruise Control (ACC), it can detect vehicles to distances of approximately 110 m (360 ft) and operates at all speeds. See Adaptive Cruise Control on page 9-40.

{ Warning
Detecting the Vehicle Ahead
FCA is a warning system and does not apply the brakes. When approaching a slower-moving or stopped vehicle ahead too rapidly, 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, or if your vehicle is equipped with Adaptive Cruise Control (ACC), through vehicle personalization. See the “Auto Collision Preparation” portion of “Collision/Detection Systems” under Vehicle Personalization on page 5-43.
FCA warnings will not occur unless the FCA system detects a vehicle ahead. When a vehicle is detected ahead, 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.

Tailgating Alert
Without Head-Up Display When your vehicle approaches another detected vehicle too rapidly, the red FCA display will flash on the windshield. Also, either eight high-pitched beeps will sound from the front, or both sides of the Safety Alert Seat will pulse five times. 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 the driving situation dictates. Cruise control may be disengaged when the Collision Alert occurs.
The vehicle-ahead indicator will display amber when you are following a detected vehicle ahead much too closely. Selecting the Alert Timing

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. If your vehicle is equipped with Adaptive Cruise Control (ACC), changing the FCA timing setting automatically changes the following gap setting (Far, Medium, or Near). 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 camera sensor and the front of the vehicle may correct the issue.
Active Emergency Braking System If the vehicle has Adaptive Cruise Control (ACC) it also has the Active Emergency Braking System, which includes Intelligent Brake Assist (IBA) and the Automatic Collision Preparation (ACP) System. These systems can provide a boost to braking or automatically brake the vehicle to help avoid or lessen the severity of crashes. Intelligent Brake Assist (IBA) IBA may activate when the brake pedal is applied quickly by providing a boost to braking based on the speed of approach and distance to a vehicle ahead. Minor brake pedal pulsations or pedal movement during this time is normal and the brake pedal should continue to be applied as needed. IBA will automatically disengage only when the brake pedal is released.
{ Warning
IBA may increase vehicle braking in situations when it may not be necessary. You could block the flow of traffic. If this occurs, take your foot off the brake pedal and then apply the brakes as needed.
Automatic Collision Preparation (ACP) System ACP may help reduce crash damage by applying the vehicle’s brake system and has a detection range of approximately 60 m (197 ft). Braking can only occur if a vehicle is detected ahead in your path. This is shown by the FCA vehicle-ahead indicator being lit. See Forward Collision Alert (FCA) System on page 9-53.

{ Warning
ACP is an emergency crash preparation feature and is not designed to avoid crashes. Do not rely on ACP to brake the vehicle. ACP may not:
. Respond to stopped vehicles,
pedestrians, or animals.
. Detect a vehicle ahead on
winding or hilly roads.
. Detect a stopped or
slow-moving vehicle or other object ahead.
. Detect a vehicle when
weather limits visibility, such as in fog, rain, or snow. In these situations, ACP sensor performance is limited.

Warning (Continued)
Complete attention is always required while driving, and you should be ready to take action and apply the brakes and/or steer the vehicle to avoid crashes.
Brake Preparation When quickly approaching a vehicle ahead, Brake Preparation reduces brake response time by having the brake system prepared for driver braking to occur more rapidly.
Automatic Braking In some imminent front-end crash situations, if the driver has not applied the brakes, Automatic Braking applies the brakes to help reduce crash damage. It may even help avoid some very low speed crashes. Automatic Braking may slow the vehicle to a complete stop to try to avoid a potential crash. If this
happens, Automatic Braking will engage the Electric Parking Brake (EPB) to hold the vehicle at a stop. To release the EPB, press the EPB button. A firm press of the accelerator pedal will also release Automatic Braking and the EPB.
{ Warning Automatic Braking may automatically brake the vehicle in situations where it may be unnecessary. It could respond to a turning vehicle ahead, guardrails, signs, and other non-moving objects. This could be uncomfortable and startling. To override Automatic Braking, firmly press the accelerator pedal, if it is safe to do so.
Automatic Braking can be disabled or reduced through vehicle personalization. See the “Auto Collision Preparation” portion of

Using the Automatic Collision Preparation System while towing a trailer could cause you to lose control of the vehicle and crash. Turn the system off when towing a trailer.
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 Detection Zones
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. Before making a lane change, always check mirrors, glance over your shoulder, and use the turn signals.
The SBZA sensor covers a zone of approximately one lane over from both sides of the vehicle, or 3.5 m (11 ft). The height of the zone is approximately between 0.5 m (1.5 ft) and 2 m (6 ft) off the ground. This zone starts at approximately the middle of the vehicle and goes back 5 m (16 ft).

When the vehicle is started, both outside mirror SBZA displays will briefly come on to indicate the system is operating. When the vehicle is moving forward, the left- or right-side mirror display will light up if a vehicle is detected in that blind zone. If the turn signal is activated in the same direction of a detected vehicle, this display will flash as an extra warning not to change lanes.
SBZA can be disabled through vehicle personalization. See “Collision/Detection Systems” under Vehicle Personalization on page 5-43. If SBZA is disabled by the driver, the SBZA mirror displays will not light up. When the System Does Not Seem to Work Properly SBZA displays may not come on when passing a vehicle quickly or when towing a trailer. The SBZA detection zones that extend back from the side of the vehicle do not move further back when a trailer is towed. Use caution while changing lanes when towing a trailer. SBZA may alert to objects attached to the vehicle, such as a trailer, bicycle, or object extending out to either side of the vehicle. This is normal system operation; the vehicle does not need service. SBZA may not always alert the driver to vehicles in the side blind zone, especially in wet conditions. The system does not need to be
serviced. The system may light up due to guardrails, signs, trees, shrubs, and other non-moving objects. This is normal system operation; the vehicle does not need service. SBZA may not operate when the SBZA sensors in the left or right corners of the rear bumper are covered with mud, dirt, snow, ice, or slush, or in heavy rainstorms. For cleaning instructions, see "Washing the Vehicle" under Exterior Care on page 10-77. 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.

Lane Departure Warning (LDW) If equipped, LDW may help avoid crashes due to unintentional lane departures. It may provide a warning if the vehicle is crossing a detected lane marking without using a turn signal in the lane departure direction. LDW uses a camera sensor to detect the lane markings. It only operates at speeds of 56 km/h (35 mph) or greater. When the vehicle crosses a detected lane marking, the LDW indicator will flash and either three beeps will be sounded from the left or right side, or three Safety Alert
Seat pulses will occur on the left or right side of the seat, depending on the lane departure direction. LDW will not warn if the turn signal is on in the departure direction, or if a sharp maneuver is made. { Warning
The LDW system is an aid to help the vehicle stay in the driving lane. It does not steer the vehicle. The LDW system may not:
. Provide enough time to avoid
a crash.
. Detect lane markings under bad weather conditions or if the windshield is dirty.
. Detect lane markings and will
not detect road edges. . Warn that the vehicle is
crossing a lane marking if the system does not detect the lane marking.
(Continued)
Warning (Continued)
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 marker. Even with LDW, 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 clean and do not use LDW in bad weather conditions.
How the System Works The LDW camera sensor is on the windshield ahead of the rearview mirror. To turn LDW on and off, press @ to the left of the steering wheel. The control indicator will light when LDW is on.

{ Warning
LDW does not provide a warning to help avoid a crash, unless it detects the lane markings. LDW may not detect the lane markings if the camera sensor is blocked by dirt, snow, or ice, or if the windshield is damaged. It may also not detect a lane 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 camera sensors clean and in good repair.
LDW warnings may occur due to tar marks, shadows, cracks in the road, or other road imperfections. This is normal system operation; the vehicle does not need service.
When the System Does Not Seem to Work Properly If the LDW symbol does not appear when the system is on and the vehicle is traveling at least 56 km/h (35 mph):
The lane markings on the road may not be seen. The camera sensor may be blocked by dirt, snow, or ice. The windshield may be damaged. The weather may be limiting visibility.
This is normal operation; the vehicle does not need service. Clean the windshield. Lane markings may not be detected on curves, highway exit ramps, or hills; or due to poor visibility. If the LDW camera system does not seem to operate properly, cleaning the outside of the windshield in front of the camera sensor may correct the issue.
When the vehicle is started, the LDW indicator on the instrument cluster will come on briefly. If LDW is on, the LDW indicator will appear green if the system detects a left or right lane marking while the vehicle is traveling at 56 km/h (35 mph) or greater. If the vehicle crosses a detected lane marking without using the turn signal in the lane departure direction, this indicator will change to amber and flash. In addition, three beeps will sound from the left or right side, or the Safety Alert Seat will pulse three times on either the left or right side of the seat, depending on the lane departure direction.

Driving and Operating
Fuel Use of the recommended fuel is an important part of the proper maintenance of this vehicle. When driving in the U.S., 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.
If the vehicle has a yellow fuel cap, E85 or FlexFuel can be used in the vehicle. See E85 or FlexFuel on page 9-64.
Recommended Fuel If the vehicle has a 2.5L L4 engine or a 3.6L V6 engine, use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, an audible knocking noise, commonly referred to as spark knock, might be heard when driving. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If heavy knocking is heard when using gasoline rated at 87 octane or higher, the engine needs service. If the vehicle has the 2.0L L4
engine, use premium unleaded gasoline with a posted octane rating of 91 or higher. You can also use regular unleaded gasoline rated at 87 octane or higher, but the vehicle's acceleration could be slightly reduced, and a slight audibleknocking noise, commonly referred to as spark knock, might be heard. If the octane is less than 87, a heavy knocking noise might be heard when driving. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you could damage the engine. If heavy knocking is heard when using gasoline rated at 87 octane or higher, the engine needs service.
Use of Seasonal Fuels Use summer and winter fuels in the appropriate season. Driving or starting could be affected if the incorrect fuel is used. Drive the vehicle with the engine running until the fuel is a 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 flex fuel 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 that are not reformulated for low emissions can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). Do not use gasolines 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.
Gasoline Specifications At a minimum, gasoline should meet ASTM specification D 4814. Some gasolines contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT. See “Prohibited Fuels" in Recommended Fuel on page 9-62.
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 5-16. 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, or any other fuel not recommended. Costly repairs caused by use of improper fuel would not be covered by the vehicle warranty.

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 a yellow fuel cap can use either unleaded gasoline or fuel containing up to 85% ethanol (E85). All other vehicles should use only the unleaded gasoline as described in Recommended Fuel on page 9-62.
The use of E85 or FlexFuel is encouraged when the vehicle is designed to use it. E85 or FlexFuel is made from renewable sources. To help locate fuel stations that carry E85 or FlexFuel, the U.S. Department of Energy has an alternative fuel website. See www.afdc.energy.gov/afdc/locator/ stations. E85 or FlexFuel should meet ASTM Specification D 5798 or CAN/ CGSB–3.512 in Canada. Do not use the fuel if the ethanol content is greater than 85%. Fuel mixtures that do not meet ASTM or CGSB specifications can affect driveability and could cause the malfunction indicator lamp to come on. 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 9-65.
{ 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.
{ 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.

Driving and Operating
Towing a trailer requires a certain amount of experience. The combination you are driving is longer and not as responsive as the vehicle itself. Get acquainted with the handling and braking of the rig before setting out for the open road. Before starting, check all trailer hitch parts and attachments, safety chains, electrical connectors, lamps, tires, and mirrors. If the trailer has electric brakes, start the combination moving and then apply the trailer brake controller by hand to be sure the brakes work. During the trip, check occasionally to be sure that the load is secure and the lamps and any trailer brakes still work. Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving the vehicle without a trailer. This can help to avoid heavy braking and sudden turns.
Passing More passing distance is needed when towing a trailer. The combination will not accelerate as quickly and is longer so it is necessary to go much farther beyond the passed vehicle before returning to the lane. Backing Up Hold the bottom of the steering wheel with one hand. To move the trailer to the left, move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you. Making Turns
{ Caution
Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle.
(Continued)
Caution (Continued)
The vehicle could be damaged. Avoid making very sharp turns while trailering.
When turning with a trailer, make wider turns than normal. Do this so the trailer will not strike soft shoulders, curbs, road signs, trees, or other objects. Avoid jerky or sudden maneuvers. Signal well in advance. If the trailer turn signal bulbs burn out, the arrows on the instrument cluster will still flash for turns. It is important to check occasionally to be sure the trailer bulbs are still working. Driving on Grades Reduce speed and shift to a lower gear before starting down a long or steep downgrade. If the transmission is not shifted down, the brakes might get hot and no longer work well.

Vehicles can tow in D (Drive). Shift the transmission to a lower gear if the transmission shifts too often under heavy loads and/or hilly conditions. When towing at high altitude on steep uphill grades, consider the following: Engine coolant will boil at a lower temperature than at normal altitudes. If the engine is turned off immediately after towing at high altitude on steep uphill grades, the vehicle may show signs similar to engine overheating. To avoid this, let the engine run while parked, preferably on level ground, with the automatic transmission in P (Park) for a few minutes before turning the engine off. If the overheat warning comes on, see Engine Overheating on page 10-20.
Driving and Operating

Parking on Hills
{ Warning
Parking the vehicle on a hill with the trailer attached can be dangerous. If something goes wrong, the rig could start to move. People can be injured, and both the vehicle and the trailer can be damaged. When possible, always park the rig on a flat surface.
If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the wheels into the curb if facing downhill or into traffic if facing uphill.
2. Have someone place chocks
under the trailer wheels.
3. When the wheel chocks are in
place, release the regular brakes until the chocks absorb the load.
4. Reapply the brake pedal. Then
apply the parking brake and shift into P (Park).
5. Release the brake pedal. Leaving After Parking on a Hill 1. Apply and hold the brake pedal. 2. Start the engine. 3. Shift into a gear. 4. Release the parking brake. 5. Let up on the brake pedal. 6. Drive slowly until the trailer is
clear of the chocks.
7. Stop and have someone pick up
and store the chocks.
Maintenance when Trailer Towing The vehicle needs service more often when pulling a trailer. See Maintenance Schedule on page 11-3. Things that are especially important in trailer operation are automatic transmission fluid, engine oil, axle

curb weight of the vehicle, any cargo carried in it, and the people who will be riding in the vehicle. If there are a lot of options, equipment, passengers, or cargo in the vehicle, it will reduce the tongue weight the vehicle can carry, which will also reduce the trailer weight the vehicle can tow. If towing a trailer, the tongue load must be added to the GVW because the vehicle will be carrying that weight, too. See Vehicle Load Limits on page 9-11.

Driving and Operating
lubricant, belts, cooling system, and brake system. It is a good idea to inspect these before and during the trip. Check periodically to see that all hitch nuts and bolts are tight.
Trailer Towing (With V6 Engine) Before pulling a trailer, three important considerations have to do with weight: . Weight of the trailer. . Weight of the trailer tongue.
Total weight on your vehicle's tires.
Weight of the Trailer How heavy can a trailer safely be? It should never weigh more than 454 kg (1,000 lb). But even that can be too heavy. It depends on how the rig is used. For example, speed, altitude, road grades, outside temperature, and
how much the vehicle is used to pull a trailer are all important. It can depend on any special equipment on the vehicle, and the amount of tongue weight the vehicle can carry. See “Weight of the Trailer Tongue” later in this section. Maximum trailer weight is calculated assuming only the driver is in the tow vehicle and it has all the required trailering equipment. The weight of additional optional equipment, passengers, and cargo in the tow vehicle must be subtracted from the maximum trailer weight. Ask your dealer for trailering information or advice, or write us at our Customer Assistance Offices. See Customer Assistance Offices on page 13-3. Weight of the Trailer Tongue The tongue load (1) of any trailer is an important weight to measure because it affects the total gross weight of the vehicle. The Gross Vehicle Weight (GVW) includes the

Towing Equipment
Hitches Use the correct hitch equipment. See your dealer or a hitch dealer for assistance.
The rear bumper on the vehicle is not intended for hitches. Do not attach rental hitches or other bumper-type hitches to it. Use only a frame-mounted hitch that does not attach to the bumper. . Will any holes be made in the body of the vehicle when the trailer hitch is installed? If so, seal the holes when the hitch is removed. If the holes are not sealed, dirt, water, and deadly carbon monoxide (CO) from the exhaust can get into the vehicle. See Engine Exhaust on page 9-23.
Safety Chains Always attach chains between the vehicle and the trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Leave enough slack so the rig can turn. Never allow safety chains to drag on the ground. Trailer Brakes Does the trailer have its own brakes? Be sure to read and follow the instructions for the trailer brakes so they are installed, adjusted, and maintained properly. Because the vehicle has antilock brakes, do not tap into the vehicle's brake system. If this is done, both brake systems will not work well, or at all.
The trailer tongue (1) should weigh 10 percent of the total loaded trailer weight (2). After loading the trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they are not, adjustments might be made by moving some items around in the trailer. Total Weight on Your Vehicle's Tires Be sure the vehicle's tires are inflated to the upper limit for cold tires. These numbers can be found on the Tire and Loading Information label. See Vehicle Load Limits on page 9-11. Make sure not to go over the GVW limit for the vehicle, including the weight of the trailer tongue.
