Using the electronic shift 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.

4L (4WD Low) - Uses extra gearing to provide maximum power to all
four wheels. 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; 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 4WD control between 2H and 4H at any forward speed.
Note: Do not perform this operation at speeds above 72 km/h (45 mph)
if the outside temperature is below 0°C (32°F).

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. Depress the brake

3. On vehicles equipped with an automatic transmission, place the
transmission in N (Neutral); on vehicles equipped with a manual
transmission, depress the clutch.

4. Move the 4WD control to the desired position.
• If shifting into 4L (4WD Low), wait for the LOW RANGE light in the

instrument cluster to turn on indicating the shift is complete.
