LIMITED SLIP DIFFERENTIAL
This axle provides added traction onslippery surfaces, particularly when onewheel is on a poor traction surface. Undernormal conditions, the limited-slip axlefunctions like a standard rear axle. The axlemay exhibit a slight noise or vibrationduring tight turns with low vehicle speed.This is normal behavior and indicates theaxle is working.
ELECTRONIC LOCKING
DIFFERENTIAL
Note:The electronic locking differential isfor off-road use only and is not for use ondry pavement. Using the electronic lockingdifferential on dry pavement will result inincreased tire wear, noise and vibration.
The electronic locking differential is adevice housed in the rear axle that allowsboth rear wheels to turn at the samespeed. The electronic locking differentialcan provide additional traction should yourvehicle become stuck. You can activatethe differential electronically and shift iton the fly within the differential operatingspeed range. The differential is for use inmud, rocks, sand, or any off-road conditionwhere you need maximum traction. It isnot for use on dry pavement.
The following conditions will affect theelectronic locking differential:
•On 2WD vehicles and 4WD vehicles in2H (4X2) or 4H (4X4 High), the ELDwill not engage if the vehicle speed isabove 20 mph (32 km/h).
•On 2WD vehicles and 4WD vehicles in2H (4X2) or 4H (4X4 High), the ELDwill automatically disengage at speedsabove 25 mph (40 km/h) and willautomatically reengage at speedsbelow 20 mph (32 km/h).
•On 4WD vehicles in 4L (4X4 Low), theELD can be engaged at any speed andwill not automatically disengage.
Activating the Electronic LockingDifferential (If Equipped)
Note:Do not use electronic lockingdifferential on dry, hard surfaced roads.Doing so will produce excessive noise,vibration and increase tire wear.
Note:If the electronic locking differentialhas difficulty disengaging, release theaccelerator pedal and turn the steeringwheel in the opposite direction while rolling.

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 77).
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 selector leverto position P, switch the engine off andapply the parking brake. Inspect theaccelerator pedal for any interference. Ifnone are found and the condition persists,have your vehicle towed to the nearestauthorized 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 system is disabled, normalbraking is still effective. If thebrake warning lamp illuminateswhen you release the parking brake, havethe system checked by an authorizeddealer.
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.

Using the Rear View CameraSystem
The rear view camera system displayswhat is behind your vehicle when you placethe transmission in reverse (R).
The system uses three types of guides tohelp you see what is behind your vehicle:
•Active guidelines: Show the intendedpath of your vehicle when reversing.
•Fixed guidelines: Show the actual pathyour vehicle is moving while reversingin a straight line. This can be helpfulwhen backing into a parking space oraligning your vehicle with anotherobject behind you.
•Centerline: Helps align the center ofyour vehicle with an object (forexample, a trailer).
Note:If the transmission is in reverse (R)and the luggage compartment is ajar, norear view camera features are displayed.
Note:If the image comes on while thetransmission is not in reverse (R), have thesystem inspected by an authorized dealer.
Note:When towing, the camera only seeswhat is being towed behind your vehicle.This might not provide adequate coverageas it usually provides in normal operationand some objects might not be seen. Insome vehicles, the guidelines may disappearonce the trailer tow connector is engaged.
The camera may not operate correctlyunder the following conditions:
•Nighttime or dark areas if the reverselamps are not operating.
•Mud, water or debris obstructs thecamera's view. Clean the lens with asoft, lint-free cloth and non-abrasivecleaner.
•The camera is misaligned due todamage to the rear of your vehicle.
To access any of the rear view camerasystem settings, make the followingselections in the touch screen when thetransmission is not in reverse (R):
•Menu > Vehicle > Rear View Camera
After changing a system setting, the touchscreen shows a preview of the selectedfeatures.

If the steering wheelposition is changed while reversing, thevehicle might deviate from the originalintended path.
The active guidelines fade in and outdepending on the steering wheel position.The active guidelines are not shown whenthe steering wheel position is straight.
Always use caution while reversing.Objects in the red zone are closest to yourvehicle and objects in the green zone arefarther away. Objects are getting closer toyour vehicle as they move from the greenzone to the yellow or red zones. Use theside view mirrors and rear view mirror toget better coverage on both sides and rearof your vehicle.
Enhanced Park Aids
Note:Enhanced park aids is only availablewhen the transmission is in reverse (R).
Note:The reverse sensing system is noteffective at speeds above 3 mph (5 km/h)and may not detect certain angular ormoving objects.
The system uses red, yellow and greenhighlights which appear on top of the videoimage when an object is detected by thereverse sensing system. The alert highlightsthe closest object detected. The reversesensing alert can be disabled and if visualpark aid alert is enabled, highlighted areasare still displayed.

STEERING
To help prevent damage to the powersteering system:
•Never hold the steering wheel at itsfurthest turning points (until it stops)for more than three to five secondswhen the engine is running.
•Do not operate the vehicle with a lowpower steering pump fluid level (belowthe MIN mark on the reservoir).
•Some noise is normal during operation.If excessive, check for low powersteering pump fluid level beforeseeking service by your dealer.
•Heavy or uneven efforts may be causedby low power steering fluid. Check forlow power steering pump fluid levelbefore seeking service by your dealer.
•Do not fill the power steering pumpreservoir above the MAX mark on thereservoir, as this may result in leaksfrom the reservoir.
If the power steering system breaks down(or if the engine is turned off), you cansteer the vehicle manually, but it takesmore effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper vehicle alignment
If any steering components are serviced orreplaced, install new fasteners (many arecoated with thread adhesive or haveprevailing torque features which may notbe re-used). Never re-use a bolt or nut.Torque fasteners to specifications.
A high crown in the road or high crosswindsmay also make the steering seem towander or pull.
