Only) CAUTION!• When installing the Integrated Power Module
cover, it is important to ensure the cover is prop-
erly positioned and fully latched. Failure to do so
may allow water to get into the Integrated Power
Module, and possibly result in a electrical system
failure.
• When replacing a blown fuse, it is important to
use only a fuse having the correct amperage
rating. The use of a fuse with a rating other than
indicated may result in a dangerous electrical
system overload. If a properly rated fuse contin-
ues to blow, it indicates a problem in the circuit
that must be corrected.460 MAINTAINING YOUR VEHICLE

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:
• Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Integrated Power Module, located in the
engine compartment. The I.O.D. cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
• The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
• As an alternative to the above steps you may, discon-
nect the negative cables from both batteries.
• Anytime 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 minutes in the fresh air and high blower setting. This will
insure 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 gages in the Instrument Cluster will do
a full sweep, when the ignition key is cycled to RUN. This
is a normal condition.
