Activating the electronic locking differential (ELD)
The ELD can be turned on by
pulling the knob on the 4WD control
toward you while the control is in
either 4H (4X4 High) or 4L (4X4
Low) mode.
Once the knob is pulled, the
light located on the control will
blink for approximately two seconds
and then it will remain solid.
The
indicator light will also
display in the message center.
Once the
light on the control
remains solid and the indicator
light is displayed in the message
center, both rear wheel axle shafts
will be locked together providing
added traction.
If the
light blinks for 10 seconds, then turns off, and the indicator
light in the message center turns off, 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
4X4 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.
Driving off-road with truck and utility vehicles
4WD vehicles are specially equipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
How your vehicle differs from other vehicles
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
