LOW (4WD Low) can be engaged, the vehicle speed must be

below 3 mph (5 km/h) with the brake pedal depressed and the

transmission in N (Neutral). This vehicle is equipped with a

non-synchronous low range gearset which will not allow the

transfer case to shift into 4X4 LOW (4WD Low) if vehicle speed

is above 3 mph (5 km/h). It is recommended that a shift to 4X4

LOW (4WD Low) is performed while the vehicle speed is below 3

mph (5 km/h).

The 4WD system:

• provides 4x4 High engagement and disengagement while the vehicle is

moving.

• is operated by a rotary control located on the instrument panel that

allows you select 2WD, 4x4 High or 4x4 Low operation.

• uses auto-manual hub locks that can be engaged and disengaged

automatically based on the 4x4 mode selected.

• auto-manual hub locks can be

manually overridden by rotating

the hub lock control from AUTO

to LOCK if desired.

• automatic operation of the

hub locks is recommended, and

will increase fuel economy

• For proper operation, make

sure that each hub is fully

engaged and that both hub

locks are set to the same position (both set to LOCK or both

set to AUTO). To engage LOCK, turn the hub locks completely

clockwise; to engage AUTO, turn the hub locks completely

counterclockwise.
