Note:
Some noise may be heard as the system shifts or engages; this is
normal.
Note:
For proper operation in 4WD Low, ensure the transfer case shift
lever is moved entirely rearward in to the 4L (4WD Low) position and
that the 4x4 Low light is illuminated.
Note:
Ideal 4L (4WD Low) shift conditions occur when the vehicle is
rolling at a speed below 3 mph (5 km/h) and the transmission is in N
(Neutral).
Using the N (Neutral) position
The transfer case N (Neutral) position overrides the transmission
and puts the vehicle in neutral regardless of transmission
gearshift lever position. The vehicle can move forward or
backward.
This position should only be used when towing the vehicle.
Do not leave the vehicle unattended with the transfer case in the
N (Neutral) position. Always set the parking brake fully and turn
off the ignition when leaving the vehicle.
