Shifting In or Out of Four-Wheel-Drive Low
Notice: 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, 3 mph
(5 km/h) or less.
. Shift the transmission into N (Neutral).
{
WARNING:
Shifting the transfer case to 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 Neutral. See
Parking
Brake on page 3 ‑ 50 .
. 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.
.
Shift the transfer case shift lever in one continuous
motion into the Four-Wheel-Drive Low position.
. When Four-Wheel-Drive Low do not drive faster
than 45 mph. This will reduce wear and extend the
life of your transfer case.
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.
