9-44 Driving and Operating
Shifting In or Out of Four-Wheel
Drive Low
Caution
Shifting the transfer case into
Four-Wheel Drive Low while
moving at speeds faster than
5 km/h (3 mph) may cause
premature wear to the transfer
case, and may cause the gears to
grind. To avoid causing premature
wear, and grinding the gears, do
not shift the transfer case into
Four-Wheel Drive Low while the
vehicle is moving faster than
5 km/h (3 mph).
Shifting into Four-Wheel Drive
Low should be done, if possible,
with the vehicle at a slight roll,
5 km/h (3 mph) or less.
Shift the transmission into
N (Neutral).
Shift the transfer case shift lever
in one continuous motion into or
out of the Four-Wheel Drive Low
position.
Warning
Shifting the transfer case to
N (Neutral) can cause the vehicle
to roll even if the transmission is
in P (Park). You or someone else
could be seriously injured. Be
sure to set the parking brake
before placing the transfer case in
N (Neutral). See Parking Brake on
page 9-54.
Shifting into Four-Wheel Drive
Low with the vehicle at a stop
may be more difficult. You may
be unable to complete the shift
to Four-Wheel Drive Low, and
the transfer case will end up in
N (Neutral). This is normal, and
is a function of the gear teeth
aligning in the transfer case.
When this happens, make sure
the engine is on, shift the
transmission momentarily to
D (Drive) and back to
N (Neutral), and then complete
the transfer case shift.
When Four-Wheel Drive Low is
engaged, vehicle speed should
be kept below 72 km/h (45 mph).
Extended high-speed operation
in Four-Wheel Drive Low may
damage or shorten the life of the
drivetrain.
Shifting In or Out of Neutral
1. With the vehicle running and the
engine at an idle, set the parking
brake.
2. Place the transmission into
N (Neutral).
Shift the transfer case in one
continuous motion into or out of the
N (Neutral) position.
