Shifting the transfer case
to
NEUTRAL can
cause your vehicle
to
roll even if the
transmission
is
in PARK (P). 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” in
the Index.
NEUTRAL: Shift the vehicle’s transfer case
to
NEUTRAL only when towing your vehicle. See
Recreational Vehicle Towing on page
4-45
for more
information.
An indicator light in the knob will show you which
position the transfer case is in. The indicator lights will
come on briefly when you turn on the ignition and
one will stay on. If the lights do not come on, you should
take your vehicle
to
your dealer for service. An
indicator light will flash while shifting the transfer case.
It
will remain illuminated when the shift is complete.
If
for some reason the transfer case cannot make
a requested shift, it will return
to
the last chosen
setting.
If
the SERVICE 4WD light
on
the instrument panel
cluster stays on, you should take your vehicle to your
dealer for service. See Service Four-Wheel Drive
Warning Light on page
3-47
for further information.
Shifting into 4HI
or
A4WD
Turn the knob
to
4HI
or A4WD. This can be done at any
speed and the indicator light will flash while shifting.
It
will remain illuminated when the shift is complete.
Shifting into 2HI
Turn the knob
to
2HI. This can be done at any speed.
Shifting into 4L0
To shift
to
4L0, the vehicle’s engine must be running
and the vehicle must be stopped or moving less than
2 mph (3.2 km/h) with the transmission in NEUTRAL
(N).
The preferred method for shifting into 4LO
is
to
have your
vehicle moving
1
or 2 mph
(1.6
to
3.2 km/h). Turn the
knob
to
4L0. You must wait for the 4LO indicator light
to
stop flashing and remain illuminated before shifting your
transmission into gear.
If
you turn the knob to 4LO when your vehicle is in gear
and/or moving, the 4LO indicator light will flash for
30 seconds and not complete the shift unless your
vehicle
is
moving less than
2
mph (3.2 km/h) and the
transmission is in NEUTRAL
(N).
After 30 seconds, the
transfer case will return
to
the setting
last
chosen.
