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 9 44 for
more information.
3. Start the vehicle or turn the
ignition to ON/RUN.
4. Put the transmission in
N (Neutral).
5. Shift the transfer case to
Two-Wheel Drive High.
6. Turn the transfer case dial
clockwise to N (Neutral) until
it stops and hold it there until
the N (Neutral) light starts
blinking. This will take at least
10 seconds. Then slowly release
the dial to the Four Wheel Drive
Low position. The N (Neutral)
light will come on when the
transfer case shift to N (Neutral)
is complete.
7. If the engine is running, verify
that the transfer case is in
N (Neutral) by shifting the
transmission to R (Reverse)
for one second, then shift the
transmission to D (Drive) for
one second.
8. Turn the ignition to ACC/
ACCESSORY, which will turn
the engine off.
9. Place the transmission shift
lever in P (Park).
10. Release the parking brake prior
to moving the vehicle.
11. Turn the ignition to LOCK/OFF.
Shifting Out of Neutral
To shift out of N Neutral do the
following:
1. Set the parking brake and apply
the regular brake pedal.
2. Turn the ignition to ON/RUN
with the engine off, and shift the
transmission to N (Neutral).
3. Turn the transfer case dial to
the desired transfer case shift
position (Two-Wheel Drive
High, Four-Wheel Drive High,
or AUTO).
After the transfer case has
shifted out of N (Neutral), the
N (Neutral) light will go out.
4. Release the parking brake prior
to moving the vehicle.
Notice: Shifting the transmission
into gear before the Four-Wheel
Drive Low indicator light has
stopped flashing could damage
the transfer case. To help avoid
damaging the vehicle, always wait
for the Four-Wheel Drive Low
indicator light to stop flashing
before shifting the transmission
into gear.
5. Start the engine and shift the
transmission to the desired
position.
