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.

Displays when the electronic limited slip differential system resumes normal function.Electronic Limited Slip Differential Restoredto Normal
Displays if the electronic limited slip differential system temporarily turns off due to overheatingor an undersized spare tire. If you have an undersized spare tire installed, replace the spare tirewith a full-sized tire as soon as possible. If not, stop the vehicle in a safe location and allow thesystem to cool.
Electronic Limited Slip DifferentialTemporarily Disabled
Displays if the electronic limited slip differential has limited functionality. This could be due toan undersized spare tire or caused by the system overheating. If you have an undersized sparetire installed, replace the spare tire with a full-sized tire as soon as possible. If you do not havean undersized spare tire installed, the vehicle has reduced functionality. Have your vehiclechecked as soon as possible.

BRAKE PRECAUTIONS
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when leaving a car wash or drivingfrom standing water to dry the brakes.
Note:Depending on applicable laws andregulations in the country where your vehiclewas originally built, the stoplamps could flashduring heavy braking. The hazard warningflashers could also turn on when your vehiclecomes to a stop.
ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEMLIMITATIONS
The anti-lock braking system does noteliminate the risk of crash 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.
Note: If the system activates, the brakepedal could pulse and travel further. Maintain pressure on the brake pedal.
BRAKE OVER ACCELERATOR
In the event the accelerator pedal becomesstuck or entrapped, apply steady and firmpressure to the brake pedal to slow thevehicle and reduce engine power. If youexperience this condition, apply the brakesand bring your vehicle to a safe stop. Movethe transmission to park (P), switch theengine off and apply the parking brake.Inspect the accelerator pedal for anyinterference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
LOCATING THE BRAKE FLUID
RESERVOIR
See Under Hood Overview (page 415).
CHECKING THE BRAKE FLUID
WARNING: Do not use any fluid otherthan the recommended brake fluid as thiswill reduce brake efficiency. Use ofincorrect fluid could result in the loss ofvehicle control, serious personal injury ordeath.
WARNING: Only use brake fluid froma sealed container. Contamination with dirt,water, petroleum products or othermaterials may result in brake systemdamage or failure. Failure to adhere to thiswarning could result in the loss of vehiclecontrol, serious personal injury or death.
WARNING: Do not allow the fluid totouch your skin or eyes. If this happens,rinse the affected areas immediately withplenty of water and contact your physician.
WARNING: The brake system couldbe affected if the brake fluid level is belowthe MIN mark or above the MAX mark onthe brake fluid reservoir.
232

1.Park your vehicle on a level surface.
2.Look at the brake fluid reservoir to seewhere the brake fluid level is relative tothe MIN and the MAX marks on thereservoir.
Note:To avoid fluid contamination, thereservoir cap must remain in place and fullytight, unless you are adding fluid.
Only use fluid that meets our specifications.See Capacities and Specifications (page467).

BRAKES – TROUBLESHOOTING
BRAKES – WARNING LAMPS
WARNING: Driving your vehicle withthe warning lamp on is dangerous. Asignificant decrease in brakingperformance may occur. It may take youlonger to stop your vehicle. Have yourvehicle checked as soon as possible.Driving extended distances with theparking brake engaged can cause brakefailure and the risk of personal injury.
If the ABS indicator illuminateswhen you are driving, this indicatesa malfunction. Your vehiclecontinues to have normal braking withoutthe anti-lock braking system function. Seean authorized dealer.
It also momentarily illuminates when youswitch the ignition on to confirm the lamp isfunctional. If it does not illuminate when youswitch the ignition on, or begins to flash atany time, have the system checked by anauthorized dealer.
The brake indicator momentarilyilluminates when you switch theignition on to confirm the lamp isfunctional. It may also illuminate when youapply the parking brake and the ignition ison. If it illuminates when your vehicle ismoving, make sure the parking brake isdisengaged. If the parking brake isdisengaged, this indicates low brake fluidlevel or a brake system fault. See anauthorized dealer.

BRAKES – FREQUENTLY ASKEDQUESTIONS
Is it normal for my brakes to make noise?
Occasional brake noise is normal. If ametal-to-metal, continuous grinding, orcontinuous squeal sound is present, thebrake lining could be worn-out. Havethe system checked by an authorizeddealer.
There is an electrical motor sound when Ipress on the brake pedal or activate thepark brake switch. Is this normal?
Yes, those sounds are the electronicbrake booster or the electronic parkbrake operating.
Note: Brake dust could accumulate on thewheels, even under normal drivingconditions. Some dust is normal as thebrakes wear and does not contribute tobrake noise. See Cleaning Wheels (page431).
