Shifting To or From 4L - 4X4 LOW
Note:4L mode is not intended for use on drypavement.
1. Bring the vehicle to a rolling speed of3 mph (5 km/h) or less.
2. Place the gearshift in neutral (N).
3. Rotate the drive mode knob to desiredmode.
The information display shows a messageindicating a 4X4 shift is in progress. Theinformation display shows the system modeselected. If any of the previous shiftconditions are not present, the shift does notoccur and the information display shows theinformation guiding the driver through theproper shifting procedures. If the previousconditions are not satisfied in 30 seconds,the system reverts back to the previous 4WDmode or drive mode.
If Shift Delayed Pull Forward displays in theinformation display, transfer case gear toothblockage is present. To alleviate thiscondition, place the transmission in a forwardgear, move the vehicle forwardapproximately 5 ft (2 m), and shift thetransmission back to neutral (N) to allow thetransfer case to complete the range shift.
Operating 4WD Vehicles With Spareor Mismatched Tires
On four-wheel drive vehicles, the size of thespare tire can affect the 4X4 system. If thereis a significant difference between the sizeof the spare tire and the remaining tires, youmay have limited four-wheel drivefunctionality.
When driving with the full-size dissimilarspare wheel and tire assembly, it isrecommended that you do not:
•Exceed 50 mph (80 km/h) with a 4WDmode turned on.
•Turn on a 4WD mode unless the vehicleis stationary.
•Use a 4WD mode on dry pavement.
Use of a dissimilar spare wheel and tireassembly may lead to impairment of thefollowing:
•Comfort and noise.
•Winter weather driving capability.
•Wet driving capability.
•Four-wheel drive capability.
How Your Vehicle Differs From OtherVehicles
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.

Four-Wheel Drive (If Equipped)

LIMITED SLIP DIFFERENTIAL (IF
EQUIPPED)
The Electronic Limited Slip Differential (eLSD)system directs torque, enabling the vehicleto drive over terrain and road conditions thata conventional axle cannot. The system isactive at all times and requires no input fromthe driver.
Note:If your vehicle is not at optimaloperating conditions or a system fault ispresent, a warning may be displayed in theinstrument cluster. Depending on thewarning, your vehicle may need to beserviced. For more information regarding thesystem information messages, SeeInformation Messages (page 124).
Locking Function (If Equipped)
The lock button engages ‘lockermode’.
With the locker engaged, the systemelectronically locks the differential causingboth half shafts to turn at the same rate. Thisincreases traction during off road events.
The locker mode may automaticallydisengage based on certain conditions suchas vehicle speed. When engaged, a telltalein the instrument cluster will illuminate amberand the switch button will be illuminated.When the speed is exceeded the telltale willturn gray, the locker will be disengaged andbe in standby mode until the speedconditions are met. If the eLSD system isfaulted and the locker cannot engage, awarning message will be displayed in theinstrument cluster and the switch button willflash.
Spare Tire
If your vehicle is equipped with an ElectronicLimited Slip Differential, a spare tire of adifferent size than the tire provided, shouldnot be used. If a spare tire is installed, amessage may appear, indicating the systemhas disabled automatically or reducedfunction to prevent system overheat anddamage. It is recommended to reinstall therepaired or replaced road tire as soon aspossible. When the road tire is replaced, thesystem will resume 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 grades, 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 systemhas reached normal operating temperatures,system function will be restored and theElectronic Limited Slip Differential Restoredmessage will be displayed.

Roadside Emergencies

GENERAL INFORMATION
Use only approved wheel and tire sizes,using other sizes could damage your vehicle.If you change the diameter of the tires fromthat fitted at the factory, the speedometermay not display the correct speed. If youintend to change the size of the wheels fromthat fitted by the manufacturer, you cancheck the suitability with an authorizeddealer.
Additional information related to thefunctionality and maintenance of your tirescan be found later in this chapter. See TireCare (page 394).
You can find the recommended tire inflationpressures can on the Tire Label, which is onthe B-pillar or the edge of the driver door.You can also find this information on theSafety Compliance Certification Label, affixedto either the door hinge pillar, door-latchpost, or the door edge that meets the doorlatch post; next to the driver seating position.
We strongly recommend maintaining thesetire pressures at all times. Failure to followthe tire pressure recommendations cancause uneven treadwear patterns, reducedfuel economy, and adversely affect the wayyour vehicle handles.
Note:Check and set the tire pressure at theambient temperature in which you areintending to drive your vehicle and when thetires are cold.
Note:Check your tire pressures at least onceper month.
If your vehicle has a spare tire, set thepressure to the highest value given for yourvehicle and tire size combination.
Notice to utility vehicle and truckowners
WARNING: Utility vehicles have asignificantly higher rollover rate than othertypes of vehicles.
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.
WARNING: In a rollover crash, anunbelted person is significantly more likelyto die than a person wearing a seatbelt.
WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheel drivevehicle may accelerate better than atwo-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always drive ata safe speed.
