Shifting Out of
Four-Wheel-Low Lock
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.
To shift out of Four-Wheel-Low 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). Press and
release the Four-Wheel High or
Four-Wheel-High Lock button.
If the vehicle has a manual
transmission, the clutch pedal must
be pressed to the floor while you
press the Four-Wheel High or
Four-Wheel-High Lock button, or the
shift will not be completed. You must
wait for the Four-Wheel High 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 and Four-Wheel High ranges
or from Neutral.
If the Four-Wheel High or
Four-Wheel-High Lock button is
pressed when the vehicle is in
gear and/or moving too fast,
the Four-Wheel High or
Four-Wheel-High Lock indicator
light will flash for 15 seconds but
will not complete the shift.
Shifting Into Neutral
To shift the transfer case to Neutral:
1. Set the parking brake.
2. Start the vehicle.
3. Put the transmission in
N (Neutral). If the vehicle has a
manual transmission, press and
hold the clutch pedal down while
you perform Steps 5 through 9.
4. Shift the transfer case to
Four-Wheel High.
{ CAUTION
Shifting an all-wheel-drive
vehicle’s transfer case into
Neutral can cause the vehicle
to roll even if the automatic
transmission is in P (Park) or the
manual transmission is in any
gear. You or others could be
injured. Make sure the parking
brake is firmly set before you shift
the transfer case to Neutral.
