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 (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.
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.
²Anytime 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
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.
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
FUSE
452 MAINTAINING YOUR VEHICLE

²Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
²Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or 6 months, whichever
comes first.
Your dealer will reset the oil change indicator message
after completing the scheduled oil change. If this sched-
uled oil change is performed by someone other than your
dealer the message can be reset by referring to the steps
described under ªOdometer/Trip Odometerº under ªIn-
strument Cluster Descriptionº in Section 4 of this
manual.
At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level whilethe vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant reservoir, brake
master cylinder, power steering and transmission and
add as needed.
²Check all lights and other electrical items for correct
operation.
