CAUTION!
It is necessary to follow these steps to be certain that the
transfer case is fully in NEUTRAL (N) before recre-
ational towing to prevent damage to internal parts.
1. Bring the vehicle to a complete stop and shift the
transmission into PARK.
2. Turn OFF the engine.
3. For vehicles with Keyless Enter-N-Go, remove the
Keyless Enter-N-Go button and use the key fob to
complete this procedure. Refer to "Starting Procedures/
Keyless Enter-N-Go" in "Starting and Operating" for
further information.
4. Turn the ignition switch to the ON/RUN position, but
do not start the engine.
5. Press and hold the brake pedal.
6. Shift the transmission into NEUTRAL.
7. Using the point of a ballpoint pen or similar object,
press and hold the recessed transfer case NEUTRAL (N)
button (located by the selector switch) for four seconds,
until the light behind the N symbol starts to blink,
indicating shift in progress. The light will stop blinking
(stay on solid) when the shift to NEUTRAL is complete.
