Using a manual 4WD system (if equipped)
2H (2WD High)
– Power to the rear wheels only; used for street and
highway driving. Provides optimal smoothness and fuel economy at high
speeds.
4H (4WD High)
– Used for extra traction such as in snow or icy roads
or in off-road situations. Not intended for use on dry pavement.
N (Neutral)
– No power to either front or rear wheels.
4L (4WD Low)
– Uses extra gearing to provide maximum power to all
four wheels at reduced speeds. Intended only for off-road applications
such as deep sand, steep grades or pulling heavy objects. 4L (4WD Low)
will not engage while the vehicle is moving above 3 mph (5 km/h); this is
normal and should be no reason for concern. Refer to
Shifting to/from
4L (4WD Low)
for proper operation.
Shifting between 2H (2WD high) and 4H (4WD high)
•
Move the transfer case lever between 2H (2WD High) and 4H (4WD
High) at a stop or any forward speed up to 55 mph (88 km/h).
Note:
Do not perform this operation if the rear wheels are slipping.
Note:
Some noise may be heard as the system shifts or engages; this is
normal.
Shifting to/from 4L (4WD Low)
1. Bring the vehicle to a complete stop.
2. Place the transmission in N (Neutral).
3. Move the transfer case lever through N (Neutral) directly to the
desired position.
•
If the transfer case
will not
engage into 4L (4WD Low), allow the
vehicle to coast at a speed below 3 mph (5 km/h), then repeat Steps 2
and 3.
