Shifting from 4H (4x4 High) to 4L (4x4 Low)
1. Bring the vehicle to a stop or a speed below 5 mph (8 km/h).
2. Place the gearshift lever in N (Neutral). If the vehicle is equipped with
a manual transmission, also depress the clutch pedal.
3. Move the transfer case shift lever
through N (Neutral) directly to 4L
(4x4 Low).
4. If the shift lever does not, or only
partially moves to the 4L (4x4 Low)
position, perform a shift with the
transmission in N (Neutral) (or
clutch pedal depressed) and the
vehicle rolling at a speed below 5 mph (8 km/h). This will ensure the
transfer case is fully engaged into 4L (4x4 Low).
Shifting from 4L (4x4 Low) to 4H (4x4 High) or 2H (2WD)
1. Bring the vehicle to a stop or a speed below 5 mph (8 km/h).

a manual transmission, also depress the clutch pedal.
3. Move the transfer case shift lever
through N (Neutral) directly to 4H
(4x4 High) or 2H (2WD).
4. If the transfer case will not
engage into 4H (4x4 High) or 2H
(2WD), perform a shift with the
transmission in N (Neutral) (or
clutch pedal depressed) and the
vehicle rolling at a speed below 5 mph (8 km/h).
5. If shifting to 2H (2WD) with the vehicle at a complete stop, disengage
the locking hubs (optional) by rotating the hub lock control from LOCK
to FREE.
Using the N (Neutral) position
The transfer case neutral position overrides the transmission and
puts the vehicle in neutral regardless of transmission gearshift
lever position. The vehicle can move forward or backwards.
