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 system requires service. Have your vehicle checked as soon as possible.Electronic Limited Slip Differential Off SeeOwner's Manual
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.

WHAT IS DRIVE MODE CONTROL
Your vehicle has various drive modes thatyou can select for different drivingconditions. Depending on the drive modethat you select, the system adjusts variousvehicle settings.
HOW DOES DRIVE MODE
CONTROL WORK
Drive mode control adjusts your vehicleconfiguration for each mode you select.
Changing the drive mode adjusts thesteering effort and feel of the steeringsystem.
The stability and traction control assist yourvehicle control in adverse conditions orhigh-performance driving.
Throttle control enhances the powertrainresponse, transmission controls becomeoptimized with shift schedules, andfour-wheel drive settings are optimized andtuned to each mode.
Changing the drive mode can engage ordisengage the electronic locking differentials.
Changing the drive mode changes thefour-wheel drive mode to the default settingfor the selected drive mode.
Note:The system has diagnostic checks thatcontinuously monitor the system for properoperation. If a mode is unavailable due to asystem fault, the drive mode system defaultsto normal. When the system defaults tonormal, the driveline settings remain thesame as prior to the system fault.
Note:The system reverts to the normalmode each time you start your vehicle. Atstartup the system also displays a prompton the instrument cluster display that givesyou the option to return to the previouslyselected drive mode during the last ignitioncycle. If you select yes, the system returnsto the last selected drive mode and thedefault driveline settings associated withthat mode. If you select no, the systemremains in normal mode and the drivelinesettings remain the same as selected in theprior ignition cycle. If you do not select yesor no, the system stays in normal mode andthe driveline settings remain the same asselected in the prior ignition cycle.

SELECTING A DRIVE MODE
Rotate the drive mode control on the centerconsole to select or change a drive mode.
Note:Button icons vary depending on thevehicle.
DRIVE MODES
CONSERVE - 4X4
For efficient driving. It helps deliver maximumfuel efficiency and increases driving range.
Two-wheel drive high is the defaultfour-wheel drive mode. Four-wheel drive lowis not available in conserve mode.
The electronic locking differential is availablebelow 25 mph (40 km/h). See What Is theElectronic Limited-Slip Differential (page230).
CONSERVE - 4X2
For efficient driving. It helps deliver maximumfuel efficiency and increases driving range.
The electronic locking differential is availablebelow 25 mph (40 km/h). See What Is theElectronic Limited-Slip Differential (page230).
DEEP CONDITIONS - 4X4
Used for crossing terrain that has deformabledeep, rutted surfaces such as mud, deepsnow or deep sand. Do not use on dry, hardsurfaced roads.
Four-wheel drive high is the defaultfour-wheel drive mode. Four-wheel drive lowis selectable in deep conditions mode.
The electronic locking differential engageswhen you select this mode at any speed, andyou can disengage it at any time using thebutton. See What Is the ElectronicLimited-Slip Differential (page 230).
