Activating the electronic locking differential (ELD)

The ELD can be turned on by

pulling the 4WD control knob

toward you (4x4 vehicles) or by

turning the ELD control knob from

OFF to ON (4x2 vehicles).

Once the indicator light is displayed

in the message center, both rear

wheel axle shafts will be locked

together providing added traction.

If the indicator does not come on, or the indicator turns off while

driving, one of the following has occurred:

• The vehicle speed is too high.

• The left and right rear wheel speed difference is too high during an

engagement attempt.

• The system has malfunctioned and will be accompanied by a CHECK

LOCKING DIFFERENTIAL message in the message center.

Note: If the ELD has difficulty disengaging, release the accelerator pedal

and turn the steering wheel in the opposite direction while rolling.

Basic operating principles

Do not use 4WD on dry, hard surfaced roads. Doing so will produce

excessive noise and vibration and increase tire wear. 4WD modes are

only intended for consistently slippery or loose surfaces.

Parking

On 4WD vehicles, when the transfer case is in the N (Neutral) position

for recreational towing purposes, the engine and transmission are

disconnected from the rest of the driveline. Therefore, the vehicle is free

to roll even if the automatic transmission is in P (Park) or the manual

transmission is in gear. Do not leave the vehicle unattended with the

transfer case in the N (Neutral) position. Always set the parking brake

fully and turn off the ignition when leaving the vehicle. Refer to

Recreational towing for more information.
