WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheel drivevehicle may accelerate better than atwo-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always drive ata safe speed.
Truck and utility vehicles can differ fromsome other vehicles. Your vehicle could behigher to allow it to travel over rough terrainwithout getting stuck or damagingunderbody components. The differences thatmake your vehicle so versatile also make ithandle differently than an ordinary passengercar. Always maintain steering wheel control,especially in rough terrain. Since suddenchanges in terrain can result in abruptsteering wheel motion, make sure you gripthe steering wheel from the outside. Do notgrip the spokes. Drive cautiously to avoidvehicle damage from concealed objects such
as rocks and stumps. Drive slower in strongcrosswinds which can affect the normalsteering characteristics of your vehicle. Beextremely careful when driving on pavementmade slippery by loose sand, water, gravel,snow or ice.
Note:Do not use four-wheel drive high orfour-wheel drive low mode on dry, hardsurfaced roads. Doing so can produceexcessive noise, increase tire wear and candamage drive components.
FOUR-WHEEL DRIVE LIMITATIONS
Operating Four-Wheel Drive with aSpare or Mismatched Tires (If Equipped)
On four-wheel drive vehicles, the size of thespare tire can affect the four-wheel drivesystem. If there is a significant differencebetween the size of the spare tire and theremaining tires, you could have limitedfour-wheel drive functionality. When drivingwith the full-size dissimilar spare wheel andtire assembly, we recommend that you donot:
•Exceed 50 mph (80 km/h) with afour-wheel drive mode turned on.
•Use a four-wheel drive mode on drypavement.
Driving with the full-size dissimilar sparewheel and tire assembly can limit four-wheeldrive functionality. You can experience thefollowing:
•Additional noise from the transfer caseor other drive components.
Use of a dissimilar spare wheel and tireassembly can lead to impairment of thefollowing:
•Comfort and noise.
•Winter weather driving capability.
•Wet driving capability.
•Four-wheel drive capability.
Note:Your vehicle could have a front airdam that can become damaged, due toreduced ground clearance, when taking yourvehicle off-road. You can remove this airdam by removing the eight bolts that secureit.

WHAT IS THE ELECTRONIC
LIMITED-SLIP DIFFERENTIAL
The electronic limited-slip differential systemdirects torque across the axle, enabling thevehicle to drive over terrain and roadconditions that a conventional axle cannot.The system is active at all times and requiresno input from the driver.
Note:If your vehicle is not at optimaloperating conditions or a system fault ispresent, a warning may display in theinstrument cluster. Depending on thewarning, you may need to service yourvehicle.
Operating the Electronic Limited-SlipDifferential with a Spare or MismatchedTires
If your vehicle has an electronic limited-slipdifferential, do not use a spare tire of adifferent size than the tire provided. If youhave a spare tire installed, a message mayappear indicating the system has disabledautomatically or reduced function to preventsystem overheat and damage. Werecommend you reinstall the repaired orreplaced spare tire as soon as possible.When you replace the spare tire, the systemresumes normal operation on the next keycycle.
Trailer Towing
The electronic limited-slip differentialenhances vehicle stability during trailer towoperation. During high demand traileringevents, such as steep slopes, high speedsor with a spare tire, the system may providea warning in the instrument cluster andreduce function or enter a temporarilydisabled state. To resume normal function,stop the vehicle in a safe location and allowthe unit to adequately cool. Once the systemreaches normal operating temperatures,system function restores and the electroniclimited-slip differential restored messagedisplays.

HOW DOES STABILITY CONTROL
WORK
WARNING: Vehicle modificationsinvolving braking system, aftermarket roofracks, suspension, steering system, tireconstruction and wheel and tire size maychange the handling characteristics of yourvehicle and may adversely affect theperformance of the electronic stabilitycontrol system. In addition, installing anystereo speakers may interfere with andadversely affect the electronic stabilitycontrol system. Reducing the effectivenessof the electronic stability control systemcould lead to an increased risk of loss ofvehicle control, vehicle rollover, personalinjury and death.
WARNING: Remember that evenadvanced technology cannot defy the lawsof physics. It's always possible to losecontrol of a vehicle due to inappropriatedriver input for the conditions. Aggressivedriving on any road condition can causeyou to lose control of your vehicle
increasing the risk of personal injury orproperty damage. Activation of theelectronic stability control system is anindication that at least some of the tireshave exceeded their ability to grip theroad; this could reduce the operator'sability to control the vehicle potentiallyresulting in a loss of vehicle control, vehiclerollover, personal injury and death.
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility todrive with due care and attention. Failureto follow this instruction could result in theloss of control of your vehicle, personalinjury or death.
If a driving condition activates either thestability control or traction control you mayexperience the following conditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
Electronic stability control enhances yourvehicle’s ability to prevent skids or lateralslides by applying brakes to one or more ofthe wheels individually and, if necessary,reducing engine power.
Roll Stability Control
Roll stability control enhances your vehicle’sability to prevent rollovers by detecting yourvehicle’s roll motion and the rate at which itchanges by applying the brakes to one ormore wheels individually.
Curve Control
Curve control enhances your vehicle’s abilityto follow the road when cornering severelyor avoiding objects in the roadway. Curvecontrol operates by reducing engine powerand, if necessary, applying brakes to one ormore of the wheels individually.

PARKING AID PRECAUTIONS
WARNING: To help avoid personalinjury, always use caution when in reverse(R) and when using the sensing system.
WARNING: The system may notdetect objects with surfaces that absorbreflection. Always drive with due care andattention. Failure to take care may resultin a crash.
WARNING: Traffic control systems,fluorescent lamps, inclement weather, airbrakes, external motors and fans mayaffect the correct operation of the sensingsystem. This may cause reducedperformance or false alerts.
WARNING: The system may notdetect small or moving objects, particularlythose close to the ground.
WARNING: The parking aid systemcan only assist you to detect objects whenyour vehicle is moving at parking speeds.To help avoid personal injury you musttake care when using the parking aidsystem.
WARNING: The system may notfunction if the sensor is blocked.
WARNING: In cold and severeweather conditions the system may notfunction. Rain, snow and spray can all limitsensor performance.
WARNING: If damage occurs in theimmediate area surrounding the sensor,have your vehicle checked as soon aspossible.
Note:If your vehicle sustains damageleaving the sensors misaligned, this willcause inaccurate measurements or falsealerts.
When you connect a trailer to your vehicle,the rear parking aid detects the trailer andprovides an alert. Disable the parking aidwhen you connect a trailer to prevent thealert.
Note:Connected trailers might be detectedby the vehicle and parking aid turns offautomatically in those instances.
Note:Certain add-on devices installedaround the bumper or fascia may createfalse alerts, for example, large trailer hitches,bike or surfboard racks, license platebrackets, bumper covers or any other devicethat could block the normal detection zoneof the parking aid system. Aftermarket sparetires or spare tire covers mounted to the reartailgate could cause false alerts from thepark aid system. Remove the add-on deviceto prevent false alerts.
Note: Keep the sensors free from snow, iceand large accumulations of dirt. If thesensors are covered, the system's accuracycan be affected.
Do not clean the sensors with sharp objects.

LOAD CARRYING PRECAUTIONS
Keep your loaded vehicle weight withinits design rating capability, with orwithout a trailer. Properly loading yourvehicle provides maximum return ofvehicle design performance. Before youload your vehicle, become familiar withthe following terms for determining yourvehicle’s weight rating, with or withouta trailer, from the vehicle’s Tire andLoading Information label or SafetyCompliance Certification label.
WARNING: The appropriateloading capacity of your vehicle canbe limited either by volume capacity(how much space is available) or by
payload capacity (how much weightthe vehicle should carry). Once youhave reached the maximum payloadof your vehicle, do not add morecargo, even if there is space available.Overloading or improperly loadingyour vehicle can contribute to loss ofvehicle control and vehicle rollover.
WARNING: Exceeding the SafetyCompliance Certification label vehicleweight limits can adversely affect theperformance and handling of yourvehicle, cause vehicle damage andcan result in the loss of control of yourvehicle, serious personal injury ordeath.
WARNING: Do not usereplacement tires with lower loadcarrying capacities than the originaltires because they may lower yourvehicle's GVWR and GAWR limitations.Replacement tires with a higher limitthan the original tires do not increasethe GVWR and GAWR limitations.
WARNING: Do not exceed theGVWR or the GAWR specified on thecertification label.
WARNING: Exceeding anyvehicle weight rating can adverselyaffect the performance and handlingof your vehicle, cause vehicle damageand can result in the loss of control ofyour vehicle, serious personal injuryor death.
WARNING: When loading theroof racks, we recommend you evenlydistribute the load, as well as maintaina low center of gravity. Loadedvehicles, with higher centers of gravity,may handle differently than unloadedvehicles. Take extra precautions, suchas slower speeds and increasedstopping distance, when driving aheavily loaded vehicle.
The gross combined weight must neverexceed the Gross Combined WeightRating.
