Shifting from 2WD (2WD High) to 4x4 HIGH (4WD High)
Rotate the 4WD control to the
4x4 HIGH position at speeds up to
88 km/h (55 mph).
•The electronic shift 4WD
system is designed to engage
4x4 HIGH (4WD High) when
the vehicle is moving. If

HIGH) while at complete stop,
4x4 may not engage and the
4x4 indicator may not
illuminate until the vehicle is driven above 8 km/h (5 mph).

Shifting from 4x4 HIGH (4WD High) to 2WD (2WD High)
Rotate the 4WD control to 2WD at
any forward speed. Disengagement
of the transfer case and front hubs
may be delayed due to torque bind
which is caused by driving on dry
hard surfaces or performing tight
turns while using the 4WD system.
•Yo udo notneed to operate the vehicle in R (Reverse) to disengage
your front hubs, but it will eliminate any torque bind and allow the
system to immediately disengage.
