•4H - Four-wheel drive high. SeeFour-Wheel Drive High (page 199).
•4L - Four-wheel drive low. SeeFour-Wheel Drive Low (page 200).
Note:Do not perform this operation whenyou have cruise control or trail controlselected and active. The system may notshift as expected.
Note: Do not perform this operation if therear wheels are slipping or when applyingthe accelerator pedal.
Note:When the light is solid, the systemhas achieved the desired four-wheel drivemode. When a selected four-wheel drivemode LED is blinking, the system isattempting to shift to that specificfour-wheel drive mode.
Note:When all lights are blinking, have yourvehicle serviced as soon as possible.
Note:When you achieve recreationaltowing, all lights are off and Neutral TowEnabled Leave Transmission in Neutralappears in the instrument cluster display.
Shifting to or from Four-WheelDrive Low
1.Bring your vehicle to a stop.
2.For vehicles with an automatictransmission, place in neutral (N). Forvehicles with a manual transmission,fully press the clutch pedal.
3.Push 4L on the four-wheel drive modeselector.
Note: A 4x4 Shift in Progress messageappears in the instrument cluster displayindicating the shift is in progress. If any ofthe previous shift conditions are not met,the shift should not occur and theinstrument cluster display can guide youthrough the proper shifting procedures.
Note: If Shift Delayed Drive Forwarddisplays in the instrument cluster display,place the transmission in a forward gear,move your vehicle forward approximately5 ft (1.5 m), and shift the transmission backto neutral (N) to allow the transfer case tocomplete the range shift.
FOUR-WHEEL DRIVE MODES
TWO-WHEEL DRIVE HIGH
Two-wheel drive high is for generalon-road driving. Power is sent to the rearwheels only.
Note:Two-wheel drive high can turn on oroff based on Drive Mode selection SeeG.O.A.T. Mode Control (page 260).
FOUR-WHEEL DRIVE AUTO (If
Equipped)
Four-wheel drive auto provideselectronically controlled four-wheel drivepower to both the front and rear wheels,as required, for increased traction in varyingon-road conditions. The four-wheel driveauto tuning varies based on selected DriveMode. See Selecting a Four-Wheel DriveMode (page 197).
Note:Four-wheel drive auto can turn on oroff automatically based on Drive Modeselection. See Selecting a Four-WheelDrive Mode (page 197).
FOUR-WHEEL DRIVE HIGH
Four-wheel drive high provideselectronically or mechanically lockedfour-wheel drive power to both the frontand rear wheels for use in off-road orwinter conditions such as deep snow, sandor mud. This mode is not for use on drypavement.

FOUR-WHEEL DRIVE LOW
Four-wheel drive low provideselectronically or mechanically lockedfour-wheel drive power to both the frontand rear wheels for use on low tractionsurfaces, but does so with additionalgearing for increased torque multiplication.This mode is only for off-road conditionssuch as deep sand, steep slopes, or pullingheavy objects.

WHAT IS THE ELECTRONIC
LOCKING DIFFERENTIAL
The electronic locking differential is adevice housed in the front or rear axle and,when activated allows both wheels on thataxle to turn at the same speed. Theelectronic locking differential can provideadditional traction should your vehiclebecome stuck. You can activate thedifferential electronically and shift it on thefly within the operating speed range. Theelectronic differential automaticallydisengages when the vehicle speedexceeds a set value and it automaticallyreengages when the vehicle speed goesbelow a set value. See Switching theElectronic Locking Differential On andOff (page 203). It also automaticallyengages based on certain selected G.O.A.Tmodes. See G.O.A.T. Mode Control(page 260). The electronic lockingdifferential is for use in mud, rocks, sand,or any off-road condition where you needmaximum traction. It is not for use on drypavement.
Note:The electronic locking differentialsare for off-road use only and not for use ondry pavement. Using the electronic lockingdifferentials on dry pavement results inincreased tire wear, noise and vibration ordriveline damage.
Note:The front electronic lockingdifferential is only available in four-wheeldrive low (4L).
Note:Locking the front differential reducesyour ability to make tight turning maneuversand creates additional resistance to steeringinputs.
Note:Switching the electronic lockingdifferentials off while turning results indisengagement difficulties. If the electroniclocking differential has difficultydisengaging, release the accelerator pedaland turn the steering wheel back and forthin small increments while maintainingcontrol and following a straight line.

If the front or rear indicator in the clusteris amber, both wheels of the indicated axleare locked together providing additionaltraction.
If the electronic locking differential isselected and the indicator in the cluster isgray or turns from amber to gray whiledriving, one of the following has occurred:
•Your vehicle speed is too high.
•The accelerator pedal is too high duringan engagement attempt.
•Your vehicle is experiencing ananti-lock brake activation.
•The left and right wheel speeddifference is too high during anengagement attempt.
If the electronic locking differential isselected and the indicator in the clusterdoes not illuminate, one of the followinghas occurred:
•The electronic locking differential is notallowed in the current G.O.A.T modeand is accompanied by SELECTEDLOCKING DIFFERENTIAL NOTAVAILABLE IN CURRENT Drive Modein the instrument cluster display.
