2. With the ignition switch in the ON position and theengine either OFF or running, shift the transmission
into NEUTRAL.
3. Press the desired position on the transfer case control switch.
4. After the desired position indicator light is ON (not flashing), shift the transmission back into gear. NOTE:
•
If Steps 1 or 2 of either the Preferred or Alternate
Procedure are not satisfied prior to attempting the shift
or if they no longer are being met while the shift
attempt is in process, the desired position indicator
light will flash continuously while the original position
indicator light is ON, until all requirements have been
met.
• The ignition switch must be in the ON position for a
shift to take place and for the position indicator lights
to be operable. If the ignition switch is not in the ON
position, then the shift will not take place and no
position indicator lights will be on or flashing.

Shifting Procedure
NOTE:
•If any of the requirements to select a new transfer case
position have not been met, the transfer case will not
shift. The position indicator light for the previous
position will remain ON and the newly selected posi-
tion indicator light will continue to flash until all the
requirements for the selected position have been met.
To retry a shift: return the control knob back to the
original position, make certain all shift requirements
have been met, wait five seconds and try the shift
again. •
If all the requirements to select a new transfer case
position have been met, the current position indicator
light will turn OFF, the selected position indicator light
will flash until the transfer case completes the shift.
When the shift is complete, the position indicator light
for the selected position will stop flashing and remain
ON.
