1.Grab the trailer hitch cover at the bottomand pull towards the rear of the vehicleuntil the bottom of the trailer hitch coverunsnaps from the bumper.
2. Grab the trailer hitch cover at the edgeand rotate until the top of the trailer hitchcover unsnaps from the bumper, thenremove the trailer hitch cover.
To install the trailer hitch cover:
1. Line up the snaps on the trailer hitchcover to the holes on the bumper andpush forward until it snaps into place.
Hitches
WARNING: Do not cut, drill, weld ormodify the trailer hitch. Modifying the trailerhitch could reduce the hitch rating.
Do not use a hitch that either clamps ontothe bumper or attaches to the axle.
Distribute the trailer load so 10-15% of thetotal trailer weight is on the tongue.
Integrated Hitch Rating
WARNING: Towing trailers beyondthe maximum recommended gross trailerweight exceeds the limit of your vehicleand could result in engine damage,transmission damage, structural damage,loss of vehicle control, vehicle rollover andpersonal injury.
The standard integrated hitch has two ratingsdepending on mode of operation:
•Weight-carrying mode requires a drawbar and hitch ball. The draw bar supportsall the vertical tongue load of the trailer.
•Weight-distributing mode requires anaftermarket weight-distributing system,which includes draw bar, hitch ball, springbars and snap-up brackets. This systemdistributes the vertical tongue load of thetrailer between the truck and the trailer.

Note:These are hitch ratings only. Actualvehicle ratings are dependent on engine,transmission and axle combinations.
Weight-distributing Hitch
WARNING: Do not adjust the springbars so that your vehicle's rear bumper ishigher than before attaching the trailer.Doing so will defeat the function of theweight-distributing hitch, which may causeunpredictable handling, and could resultin serious personal injury.
When hooking-up a trailer using aweight-distributing hitch, always use thefollowing procedure:
1. Park the loaded vehicle, without thetrailer, on a level surface.
2. Measure the height to the top of yourvehicle's front wheel opening on thefender. This is H1.
3. Attach the loaded trailer to your vehiclewithout the weight-distributing barsconnected.
4. Measure the height to the top of yourvehicle's front wheel opening on thefender a second time. This is H2.
5. Install and adjust the tension in theweight-distributing bars so that the heightof your vehicle's front wheel opening onthe fender is approximately half the waydown from H2, toward H1.
6. Check that the trailer is level or slightlynose down toward your vehicle. If not,adjust the ball height accordingly andrepeat Steps 2-6.
When the trailer is level or slightly nose downtoward the vehicle:
•Lock the bar tension adjuster in place.
•Check that the trailer tongue securelyattaches and locks onto the hitch.
•Install safety chains, lighting and trailerbrake controls as required by law or thetrailer manufacturer.
Safety Chains
Note:Do not attach safety chains to thebumper. Always connect the safety chainsto the frame or hook retainers of your trailerhitch.
Install trailer safety chains to the trailer hitchas recommended by the manufacturer. Crossthe chains under the trailer tongue and allowenough slack for turning tight corners. Donot allow the chains to drag on the ground.

Towing

Before Towing a Trailer
Practice turning, stopping and backing up toget the feel of your vehicle-trailercombination before starting on a trip. Whenturning, make wider turns so the trailerwheels clear curbs and other obstacles.
When Towing a Trailer
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughly afteryou have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control when carryingheavy loads or in hilly terrain. The speedcontrol may turn off automatically whenyou are towing on long, steep grades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission has a Grade Assistor Tow/Haul feature, use this featurewhen towing. This provides enginebraking and helps eliminate excessivetransmission shifting for optimum fueleconomy and transmission cooling.
•If your vehicle has AdvanceTrac withRSC, this system may turn on duringtypical cornering maneuvers with aheavily loaded trailer. This is normal.Turning the corner at a slower speedwhile towing may reduce this tendency.
•If your vehicle has Adaptive suspension,you can select NORMAL or SPORT drivecontrol modes for better experiencewhen towing a trailer. See InformationDisplays (page 119).
•If you are towing a trailer frequently inhot weather, hilly conditions, at the grosscombined weight rating (or anycombination of these factors), considerrefilling your rear axle with synthetic gearlubricant (if the axle is not already filledwith it). See Capacities andSpecifications (page 422).
•Allow more distance for stopping with atrailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1. Turn the steering wheel to point yourvehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4.Place wheel chocks in the front and backof the trailer wheels.
Note:Chocks are not included with yourvehicle.

Towing

Your vehicle may be equipped with atemporary or conventional spare tire. Atemporary spare tire is different in size(diameter or width), tread-type (All-Seasonor All-Terrain) or is from a differentmanufacturer than the road tires on yourvehicle. Consult information on the tire labelor Safety Compliance label for limitationswhen using.
Launching or Retrieving a Boat orPersonal Watercraft (PWC)
Note:Disconnect the wiring to the trailerbefore backing the trailer into the water.
Note:Reconnect the wiring to the trailerafter removing the trailer from the water.
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level to riseabove the bottom edge of the rearbumper.
•Do not allow waves to break higher than6 in (15 cm) above the bottom edge ofthe rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.
Replace the rear axle lubricant anytime therear axle has been submerged in water.Water may have contaminated the rear axlelubricant, which is not normally checked orchanged unless a leak is suspected or otheraxle repair is required.
TOWING THE VEHICLE ON FOUR
WHEELS
WARNING: If your vehicle has asteering wheel lock make sure the ignitionis in the accessory or on position whenbeing towed.
Recreational Towing
Note:Put your climate control system inrecirculated air mode to prevent exhaustfumes from entering your vehicle. SeeClimate Control (page 151).
Follow these guidelines if you have a needfor recreational towing, such as towing yourvehicle behind a motorhome. Theseguidelines are designed to prevent damageto your transmission.
Two-wheel Drive Vehicles
You cannot tow a two-wheel drive vehiclewith any wheels on the ground as vehicle ortransmission damage may occur. You musttow your vehicle with all four wheels off theground, for example when using acar-hauling trailer.

BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). During thistime, your vehicle may exhibit some unusualdriving characteristics.
Avoid driving too fast during the first 1,000 mi(1,600 km). Vary your speed frequently andchange up through the gears early. Do notlabor the engine.
Do not tow during the first 1,000 mi(1,600 km).
REDUCED ENGINE PERFORMANCE
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stop withoutwarning. Failure to follow this instructioncould result in the loss of control of yourvehicle.
If the engine coolant temperature gaugeneedle moves to the upper limit position, theengine is overheating. See Gauges (page112).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends on ambienttemperature, vehicle load and terrain. Theengine continues to operate with limitedpower for a short period of time.
If the engine temperature continues to rise,the fuel supply to the engine reduces. Theair conditioning switches off and the enginecooling fan operates continually.
1. Gradually reduce your speed and stopyour vehicle as soon as it is safe to doso.
2. Immediately switch the engine off toprevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See EngineCoolant Check (page 366).
5. Have your vehicle checked as soon aspossible.
ECONOMICAL DRIVING
Fuel economy is affected by several thingssuch as how you drive, the conditions youdrive under and how you maintain yourvehicle.
There are some things to keep in mind thatmay improve your fuel economy:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving (When runningerrands, go to the furthest destinationfirst and then work your way back home).
•Close the windows for high-speeddriving.
•Drive at reasonable speeds.
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.

Maintain coolant concentration within 48%to 50%, which equates to a freeze pointbetween -29°F (-34°C) and -35°F (-37°C).Coolant concentration should be checkedusing a refractometer. We do not recommendthe use of hydrometers or coolant test stripsfor measuring coolant concentration.
Adding Coolant
WARNING: Do not add enginecoolant when the engine is hot. Failure tofollow this instruction could result inpersonal injury.
WARNING: Do not remove thecoolant reservoir cap when the coolingsystem is hot. Wait 10 minutes for thecooling system to cool down. Cover thecoolant reservoir cap with a thick cloth toprevent the possibility of scalding andslowly remove the cap. Failure to followthis instruction could result in personalinjury.
Note: Automotive fluids are notinterchangeable. Take care not to putengine coolant in the windshield washer fluidreservoir or windshield washer fluid in theengine coolant reservoir.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
It is very important to use prediluted coolantapproved to the correct specification in orderto avoid plugging the small passageways inthe engine cooling system. See Capacitiesand Specifications (page 422). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engine orcooling system components and may not becovered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 422).Using water that has not been deionisedmay contribute to deposit formation,corrosion and plugging of the small coolingsystem passageways.
Note: Coolants marketed for all makes andmodels may not be approved to ourspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant approved to thecorrect specification. See Capacities andSpecifications (page 422).
3.Add enough prediluted coolant to reachthe correct level.

Maintenance

If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of the coolantand may cause engine damage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
Coolant Change
At specific mileage intervals, as listed in thescheduled maintenance information, thecoolant should be changed. Add predilutedcoolant approved to the correct specification.See Capacities and Specifications (page422).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambient temperature,vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone:
A warning lamp illuminates and amessage may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternating cylinderoperation. Each disabled cylinder acts as anair pump and cools the engine.
When this occurs, your vehicle still operates,however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, you canre-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for useduring emergencies only. Operate yourvehicle in fail-safe mode only as long asnecessary to bring your vehicle to rest ina safe location and seek immediate repairs.When in fail-safe mode, your vehicle willhave limited power, will not be able tomaintain high-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
WARNING: Do not remove thecoolant reservoir cap when the coolingsystem is hot. Wait 10 minutes for thecooling system to cool down. Cover thecoolant reservoir cap with a thick cloth toprevent the possibility of scalding andslowly remove the cap. Failure to followthis instruction could result in personalinjury.

Maintenance

Your vehicle has limited engine power whenin the fail-safe mode, drive your vehicle withcaution. Your vehicle does not maintainhigh-speed operation and the engine mayoperate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1. Pull off the road as soon as safelypossible and switch the engine off.
2. If you are a member of a roadsideassistance program, we recommend thatyou contact your roadside assistanceservice provider.
3.If this is not possible, wait a short periodfor the engine to cool.
4. Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5.When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.
Engine Coolant TemperatureManagement (If Equipped)
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and the vehiclemay not be able to accelerate with fullpower until the coolant temperaturereduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a long orsteep grade in high ambient temperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehicle speedcaused by reduced engine power in orderto manage the engine coolant temperature. Your vehicle may enter this mode if certainhigh-temperature and high-load conditionstake place. The amount of speed reductiondepends on vehicle loading, grade andambient temperature. If this occurs, there isno need to stop your vehicle. You cancontinue to drive.
The air conditioning may automatically turnon and off during severe operatingconditions to protect the engine fromoverheating. When the coolant temperaturedecreases to the normal operatingtemperature, the air conditioning turns on.
If the coolant temperature gauge moves fullyinto the red zone, or if the coolanttemperature warning or service engine soonmessages appear in your information display,do the following:
1.Stop your vehicle as soon as it is safe todo so. Fully apply the parking brake, shiftinto park (P) or neutral (N).
