Shifting Out of Four-Wheel Low Lock
To shift from Four-Wheel-Low Lock to Full ‐ Time
Four-Wheel Drive or Four-Wheel-High Lock, the vehicle
must be stopped or moving less than 3 mph (5 km/h)
with the transmission in N (Neutral) and the ignition in
ON/RUN. The preferred method for shifting out of
Four-Wheel-Low Lock is to have the vehicle moving
1 to 2 mph (1.6 to 3.2 km/h). Turn the dial to the
Full
‐ Time Four-Wheel Drive or Four-Wheel-High Lock
position. You must wait for the Full ‐ Time Four-Wheel
Drive or Four-Wheel-High Lock indicator light to stop
flashing and remain lit before shifting the transmission
into gear.
It is normal for the vehicle to have engagement noise
and bump when shifting between Four-Wheel Low Lock,
Full
‐ Time Four-Wheel Drive or Four-Wheel-High Lock
ranges or from N (Neutral) with the engine running.
If the Full ‐ Time Four-Wheel Drive or
Four-Wheel-High Lock position is selected when the
vehicle is in gear and/or moving, the Full
‐ Time
Four-Wheel Drive or Four-Wheel-High Lock indicator
light will flash for 30 seconds but will not complete the
shift unless the vehicle is moving less than 3 mph
(5 km/h) and the transmission is in N (Neutral).
Notice: Shifting the transmission into gear before
the indicator light stops flashing could cause
damage to the transfer case. Always wait until the
indicator light stops flashing before putting the
transmission back in gear.
Shifting into Neutral
To shift the transfer case to N (Neutral) do the following:
1. Make sure the vehicle is parked so that it will
not roll.
2. Set the parking brake and apply the regular brake
pedal. See Parking Brake on page 3 ‑ 41 .
3. Start the vehicle or turn the ignition to ON/RUN.
4. Put the transmission in N (Neutral).
5. Shift the transfer case to Full ‐ Time Four ‐ Wheel
Drive.
6. Turn the transfer case dial clockwise to N (Neutral)
position. The transfer case will not shift to
N (Neutral) unless this position is held for
10 seconds. The N (Neutral) light will come on and
then the dial can be slowly released. The dial will
be in the Four-Wheel Low Lock position but the
transfer case will be in N (Neutral) with the
N (Neutral) light on.
