WHAT IS THE PERSONAL
SAFETY SYSTEM
An advanced safety system that protectsoccupants in frontal crashes.
HOW DOES THE PERSONAL
SAFETY SYSTEM WORK
This system provides an improved level offrontal crash protection to front seatoccupants and is designed to reduce therisk of airbag-related injuries. The systemanalyzes occupant conditions and crashseverity before activating the appropriatesafety devices. During a crash, therestraints control module may deploy theseatbelt pretensioners, and one or bothstages of the dual-stage airbags based oncrash severity and occupant conditions.
PERSONAL SAFETY SYSTEM
COMPONENTS
•Driver and passenger dual-stage airbagsupplemental restraints.
•Front seat outermost seatbelts withpretensioners, energy managementretractors and seatbelt usage sensors.
•Driver seat position sensor.
•Front passenger sensing system.
•Passenger airbag off and on indicators.
•Front crash severity sensors.
•Restraints control module with impactand safing sensors.
•Restraint system warning light andtone.

•Make sure that when in operation, theextension cord plug and engine blockheater cord plug connections are freeand clear of water. This could cause anelectric shock or fire.
•If the engine block heater cord is underthe hood, do not remove the wiringfrom its original location. Do not closethe hood on the extension wiring.
•Park your vehicle in a clean area, clearof combustible materials.
•Firmly connect the engine block heatercord and the extension cord.
•Check the extension cord for heatanywhere when the system has beenoperating for approximately 30minutes.
•Unplug and properly stow the systembefore starting and driving your vehicle.The protective cover seals theterminals of the engine block heatercord plug when not in use.
•Check the engine block heater systemfor proper operation before winter.
HOW DOES THE ENGINE BLOCKHEATER WORK
The engine block heater warms the enginecoolant. This allows the climate controlsystem to quickly respond. The equipmentincludes a heater element installed in theengine block and a wire harness. You canconnect the system to a grounded 110 voltAC electrical source.
Note:The engine block heater is mosteffective when outdoor temperatures arebelow 0°F (-18°C).
USING THE ENGINE BLOCKHEATER
Make sure the receptacle terminals areclean and dry prior to use. Clean them witha dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hoursof energy per hour of use. The system doesnot have a thermostat. It achievesmaximum temperature afterapproximately three hours of operation.Using the engine block heater longer thanthree hours does not improve systemperformance and unnecessarily useselectricity.

CONNECTING A TRAILER
PRECAUTIONS
Do not tow a trailer until you drive yourvehicle at least 1,000 mi (1,600 km).
Consult your local motor vehicle laws fortowing a trailer.
See the instructions included with towingaccessories for the proper installation andadjustment specifications.
Service your vehicle more frequently if youtow a trailer. See Normal ScheduledMaintenance (page 542).
If you use a rental trailer, follow theinstructions the rental agency gives you.
When attaching the trailer wiring connectorto your vehicle, only use a proper fittingconnector that works with the vehicle andtrailer functions.
Account for the trailer coupler weight aspart of your vehicle load when calculatingthe total vehicle weight.
Do not exceed the load limits. SeeCalculating the Load Limit (page 347).
HITCHES
INSTALLING A HITCH
WARNING: Do not cut, drill, weldor modify the trailer hitch. Modifying thetrailer hitch could reduce the hitch rating.
Do not use a hitch that either clamps ontothe bumper or attaches to the axle. Youmust distribute the load in your trailer sothat 10-15% of the total weight of thetrailer is on the tongue. Do not exceed thetongue load rating indicated on the hitchreceiver.
Trailer Hitch Cover
Your vehicle has a removable trailer hitchcover. To remove the trailer hitch cover:
1.Grab the trailer hitch cover at thebottom and pull towards the rear ofthe vehicle until the bottom of thetrailer hitch cover unsnaps from thebumper.
2.Grab the trailer hitch cover at the edgeand rotate until the top of the trailerhitch cover unsnaps from the bumper,then remove 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.

HOOKING UP A TRAILER USING AWEIGHT-DISTRIBUTING HITCH
WARNING: Do not adjust the springbars so that your vehicle's rear bumperis higher than before attaching the trailer.Doing so will defeat the function of theweight-distributing hitch, which maycause unpredictable handling, and couldresult in serious personal injury.
A weight-distributing hitch helps distributetongue load to all towing vehicle and trailerwheels. For more information, visit the linksin the following table.

CONNECTING A TRAILER
Recognizing a Trailer
1.Attach the trailer and wiring connectorto your vehicle.
2.Switch on your vehicle.
3.Set up a profile for the trailer using thetouchscreen.
Note:If your vehicle does not recognize thetrailer, press and hold the brake pedal for afew seconds.
Note:Trailer profiles store trailer types,dimensions, preferences, trailer specificmileage and fuel economy.
Note:Disabling the trailer detectionnotification makes the default trailer profileactive when a connection is detected.
When attaching the trailer wiring connectorto your vehicle, only use a proper fittingconnector that works with the vehicle andtrailer functions.
Trailer Light Check
WARNING: Never connect anytrailer lamp wiring to the vehicle's taillamp wiring; this may damage theelectrical system resulting in fire. Contactyour authorized dealer as soon aspossible for assistance in proper trailertow wiring installation. Additionalelectrical equipment may be required.
Most towed vehicles require trailer lamps.Make sure all running lights, brake lights,turn signals and hazard lights are working.
Safety Chains
Install trailer safety chains to the trailerhitch as recommended by themanufacturer. Cross the chains under thetrailer coupler and allow enough slack forturning tight corners. Do not allow thechains to drag on the ground.
Note:Do not attach safety chains to thebumper. Always connect the safety chainsto the frame or hook retainers of your trailerhitch.

When towing a trailer:
•Obey country specific regulations fortowing 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 thoroughlyafter you have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) to aid engineand transmission cooling and to helpA/C performance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off when you aretowing on long, steep slopes.
•Shift to a lower gear when driving downa long or steep hill. Do not continuouslyapply the brakes, as they may overheatand become less effective.
•If your transmission has Grade Assistor Tow/Haul, use this feature whentowing. This provides engine brakingand helps eliminate excessivetransmission shifting for optimum fueleconomy and transmission cooling.
•Your vehicle has AdvanceTrac with rollstability control. When towing a trailer,additional loads could cause theAdvanceTrac system to engage duringcornering maneuvers. Reduce corneringspeeds to make sure that you canmaintain control of the vehicle andtrailer if the AdvanceTrac systemengages.
•Allow more distance for stopping witha trailer attached. Anticipate stops andgradually brake.
•Avoid parking on a slope. However, ifyou must park on a slope, turn thesteering wheel to point your vehicletires away from traffic flow, set theparking brake, place the transmissionin park (P) and place wheel chocks infront and back of the trailer wheels.
Note:Chocks are not included with yourvehicle.
LAUNCHING OR RETRIEVING
A BOAT OR PERSONAL
WATERCRAFT
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level torise above the bottom edge of the rearbumper.
•Do not allow waves to break higherthan 6 in (15 cm) above the bottomedge of the rear bumper.
Exceeding 6 in (15 cm) could allow waterto enter vehicle components, causinginternal damage to the components andaffecting driveability, emissions andreliability.
Note:Replace the rear axle lubricantanytime the rear axle has been submergedin water.
Note:Disconnect the trailer wiringconnector before backing the trailer into thewater.
Note:Reconnect the trailer wiringconnector after removing the trailer fromthe water.
