Mud and Water
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even four-wheel drive vehicles canlose traction in slick mud. If your vehicledoes slide, steer in the direction of the slideuntil you regain control of your vehicle.
After driving through mud, clean off residuestuck to rotating driveshafts and tires.Excess mud stuck on tires and rotatingdriveshafts can cause an imbalance thatcould damage drive components.
Water
If you must drive through high water, driveslowly. Traction or brake capability maybe limited.
When driving through water, determine thedepth and avoid water higher than thebottom of the hubs. If the ignition systemgets wet, your vehicle may stall.
Once through water, always try the brakes.Wet brakes do not stop your vehicle aseffectively as dry brakes. Drying can beimproved by applying light pressure to thebrake pedal while moving slowly.
Note:Driving through deep water maydamage the transmission. If the front or rearaxle is submerged in water, the axlelubricant and power transfer unit lubricantshould be checked and changed ifnecessary.
Driving on Hilly or Sloping Terrain
Although natural obstacles may make itnecessary to travel diagonally up or downa hill or steep incline, you should alwaystry to drive straight up or straight down.
Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.Whenever driving on a hill, determinebeforehand the route you will use. Do notdrive over the crest of a hill without seeingwhat conditions are on the other side. Donot drive in reverse over a hill without theaid of an observer.
When climbing a steep slope or hill, startin a lower gear rather than downshifting toa lower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If your vehicle stalls, do not try to turnaround because this could cause vehicleroll over. It is better to reverse back to asafe location.
Apply just enough power to the wheels toclimb the hill. Too much power will causethe tires to slip, spin or lose traction,resulting in loss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating.Do not descend in neutral. Disengageoverdrive or move the transmissionselector lever to a lower gear. Whendescending a steep hill, avoid sudden hardbraking as you could lose control. The frontwheels have to be turning in order to steeryour vehicle.

If your vehicle has anti-lock brakes, applythe brakes steadily. Do not pump thebrakes.
Driving on Snow and Ice
WARNING
If you are driving in slipperyconditions that require tire chains orcables, then it is critical that you drivecautiously. Keep speeds down, allow forlonger stopping distances and avoidaggressive steering to reduce the chancesof a loss of vehicle control which can leadto serious injury or death. If the rear end ofyour vehicle slides while cornering, steer inthe direction of the slide until you regaincontrol of your vehicle.
Note:Excessive tire slippage can causetransmission damage.
Four-wheel drive vehicles have advantagesover two-wheel drive vehicles in snow andice but can skid like any other vehicle.Should you start to slide while driving onsnowy or icy roads, turn the steering wheelin the direction of the slide until you regaincontrol.
Avoid sudden applications of power andquick changes of direction on snow andice. Apply the accelerator slowly andsteadily when starting from a full stop.
Avoid sudden braking. Although afour-wheel drive vehicle may acceleratebetter than a two-wheel drive vehicle insnow and ice, it will not stop any faster asbraking occurs at all four wheels. Do notbecome overconfident as to roadconditions.
Make sure you allow sufficient distancebetween you and other vehicles forstopping. Drive slower than usual andconsider using one of the lower gears. Inemergency stopping situations, apply thebrake steadily. Do not pump the brakepedal. See Hints on Driving WithAnti-Lock Brakes (page 169).
If Your Vehicle Gets Stuck In Mud orSnow
WARNING
Do not spin the wheels at over35 mph (56 km/h). The tires may failand injure a passenger or bystander.
If your vehicle gets stuck in mud or snow,it may be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.
Note:Do not rock your vehicle if the engineis not at normal operating temperature,damage to the transmission may occur.
Note:Do not rock your vehicle for morethan a minute, damage to the transmissionand tires may occur or the engine mayoverheat.
Parking
WARNINGS
If the parking brake is fully released,but the brake warning lamp remainsilluminated, the brakes may not beworking properly. See your authorizeddealer.
Always set the parking brake fullyand make sure the gearshift islatched in P (Park). Turn the ignitionto the off position and remove the keywhenever you leave your vehicle.

Four-Wheel Drive (If Equipped)

On some four-wheel drive vehicles, whenthe transfer case is in the N (Neutral)position, the engine and transmission aredisconnected from the rest of the driveline.Therefore, the vehicle is free to roll even ifthe automatic transmission is in P (Park)or the manual transmission is in gear. Donot leave the vehicle unattended with thetransfer case in the N (Neutral) position.Always set the parking brake fully and turnoff the ignition when leaving the vehicle.
Maintenance and Modifications
The suspension and steering systems onyour vehicle have been designed andtested to provide predictable performancewhether loaded or empty. For this reason,we strongly recommend that you do notmake modifications such as adding orremoving parts (i.e. lift kits or stabilizerbars) or by using replacement parts notequivalent to the original factoryequipment.
We recommend that you use caution whenyour vehicle has either a high load or device(i.e. ladder or luggage racks). Anymodifications to your vehicle that raise thecenter of gravity may cause your vehicleto roll over when there is a loss of vehiclecontrol.
Failure to maintain your vehicle correctlymay void the warranty, increase your repaircost, reduce vehicle performance andoperational capabilities and adverselyaffect you and your passenger's safety. Werecommend you frequently inspect yourvehicle's chassis components when yourvehicle is subject to off road usage.

GENERAL INFORMATION
Note:Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out. Have thesystem checked by an authorized dealer. Ifyour vehicle has continuous vibration orshudder in the steering wheel while braking,have it checked by an authorized dealer.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the AlloyWheels (page 261).
See Warning Lamps andIndicators (page 84).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Brake Assist
Brake assist detects when you brakerapidly by measuring the rate at which youpress the brake pedal. It providesmaximum braking efficiency as long as youpress the pedal, and can reduce stoppingdistances in critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarilyilluminates when you turn theignition on. If the light does notilluminate during start up, remains on orflashes, the system may be disabled. Havethe system checked by an authorizeddealer. If the anti-lock brake system isdisabled, normal braking is still effective.
If the brake warning lampilluminates when you release theparking brake, have the systemchecked by an authorized dealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note:When the system is operating, thebrake pedal will pulse and may travelfurther. Maintain pressure on the brakepedal. You may also hear a noise from thesystem. This is normal.
The anti-lock braking system will noteliminate the risks when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.

PARKING BRAKE
WARNING
Always set the parking brake fullyand make sure the transmission isplaced in park (P). Failure to set theparking brake and engage park could resultin vehicle roll-away, property damage orbodily injury. Turn the ignition to the lockposition and remove the key whenever youleave your vehicle.
Apply the parking brake whenever yourvehicle is parked. Press the pedaldownward to set the parking brake. Thebrake warning lamp in the instrumentcluster will illuminate and remainsilluminated until the parking brake isreleased.
To release, pull the brake release leverlocated at the lower left side of theinstrument panel.
If you are parking your vehicle on a gradeor with a trailer, press and hold the brakepedal down, then set the parking brake.There may be a little vehicle movement asthe parking brake sets to hold the vehicle'sweight. This is normal and should be noreason for concern. If needed, press andhold the service brake pedal down, thentry reapplying the parking brake. Chock thewheels if required. If the parking brakecannot hold the weight of the vehicle, theparking brake may need to be serviced orthe vehicle may be overloaded.
HILL START ASSIST
WARNINGS
The system does not replace theparking brake. When you leave yourvehicle, always apply the parkingbrake. Failure to leave your vehicle securelyparked may lead to a crash or injury. SeeParking Brake (page 170).
WARNINGS
You must remain in your vehiclewhen the system turns on. At alltimes, you are responsible forcontrolling your vehicle, supervising thesystem and intervening, if required. Failureto take care may result in the loss ofcontrol of your vehicle, serious personalinjury or death.
The system will turn off if amalfunction is apparent or if you revthe engine excessively. Failure totake care may result in the loss of controlof your vehicle, serious personal injury ordeath.
The system makes it easier to pull awaywhen your vehicle is on a slope without theneed to use the parking brake.
When the system is active, your vehicleremains stationary on the slope for two tothree seconds after you release the brakepedal. This allows time to move your footfrom the brake to the accelerator pedal.The system releases the brakesautomatically once the engine hasdeveloped sufficient drive to prevent yourvehicle from rolling down the slope. Thisis an advantage when pulling away on aslope, for example from a car park ramp,traffic lights or when reversing uphill intoa parking space.
Note:The system only functions when youbring your vehicle to a complete standstillin an uphill gear (for example, drive whenfacing uphill or reverse when facingdownhill).
Note:There is no warning light to indicatethe system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring yourvehicle to a complete standstill. Keepthe brake pedal pressed.

2. If the sensors detect that your vehicleis on a slope, the system activatesautomatically.
3. When you remove your foot from thebrake pedal, your vehicle remains onthe slope without rolling away forabout two to three seconds. This holdtime automatically extends if you arein the process of driving off.
4. Drive off in the normal manner. Thesystem releases the brakesautomatically.
Note:When you remove your foot from thebrake pedal and press the pedal again whenthe system is active, you will experiencesignificantly reduced brake pedal travel. Thisis normal.
