WHAT IS THE ELECTRONIC
LIMITED-SLIP DIFFERENTIAL
The electronic limited-slip differentialsystem directs torque across the axle,enabling the vehicle to drive over terrainand road conditions that a conventionalaxle cannot. The system is active at alltimes and requires no 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 orMismatched Tires
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 toprevent system overheat and damage. Werecommend you reinstall the repaired orreplaced spare tire as soon as possible.When you replace the spare tire, thesystem resumes normal operation on thenext key cycle.
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 andallow the unit to adequately cool. Oncethe system reaches normal operatingtemperatures, system function restoresand the electronic limited-slip differentialrestored message displays.
ELECTRONIC LIMITED-SLIP

BRAKE PRECAUTIONS
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when leaving a car wash ordriving from standing water to dry thebrakes.
Note:Depending on applicable laws andregulations in the country where your vehiclewas originally built, the stoplamps couldflash during heavy braking. The hazardwarning flashers could also turn on whenyour vehicle comes 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 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.
