Shifting Out of NEUTRAL

To shift out of NEUTRAL:

1. Set the parking brake and apply the regular brake

pedal.

2. Shift the transmission to NEUTRAL (N) and turn the

ignition to RUN with the engine off.

3. Press the button for the desired transfer case shift

position (2HI, 4HI, or 4LO).

4. After the transfer case has shifted out of NEUTRAL

the red light will go out.

5. Release the parking brake.

6. You may start the engine and shift the transmission

to the desired position.

Excessively shifting the transfer case into or out of the
different modes may cause the transfer case to enter the
shift protection mode. This will protect the transfer case
from possible damage and will only allow the transfer
case to respond to one shift per 10 seconds. The transfer
case may stay in this mode for up to three minutes.
