NOTE:Steps 1 through 5 are requirements that must be
met prior to depressing the transfer case Neutral (N)
button, and must continue to be met until one second
elapses and the shift has been completed. If any of these
requirements (with the exception of step 3 - key ON) are
not met prior to depressing the Neutral (N) button, or are
no longer met during the one second time, then all of the
mode position indicator lights will flash continuously
until all requirements are met, or until the Neutral (N)
button is released.NOTE:The ignition key must be ON for a transfer case
shift to take place and for the position indicator lights to
be operable. If the key is not ON, the shift will not take
place and no position indicator lights will be on or
flashing.
NOTE:Flashing Neutral position indicator light indi-
cates that shift requirements have not been met.

HAZARD WARNING FLASHER
The Hazard Warning switch is mounted on the top of the
steering column as shown in the illustration.To engage the Hazard Warning lights, depress the button
on the top of the steering column. When the Hazard
Warning switch is activated, all directional turn signals
will flash off and on to warn oncoming traffic of an
emergency. Push the button a second time to turn off the

VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle's battery:
²Disconnect the Ignition-Off Draw fuse (IOD) fuse
located in the Integrated Power Module, located in the
engine compartment. The IOD cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
²The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
²As an alternative to the above steps you may discon-
nect the negative cables from both batteries.
²Any time you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutesin the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
NOTE:When reinstalling the IOD fuse push firmly until
fully seated; the gauges in the instrument cluster will do
a full sweep when the ignition key is cycled to RUN. This
is a normal condition.
NOTE:When the vehicle is shipped from the factory,
the IOD fuse is in the up, or extracted position. If the
radio, interior lamps, keyless entry, or other features do
not work with the key OFF, check the position of the fuse
(or check to see if the fuse is blown) to ensure that it is
fully seated. When the IOD fuse is extracted, the instru-
ment cluster in the odometer window will display9NO
