Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage will also weaken the fabric.
If the belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the belts from the
vehicle to wash them.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
FUSE BLOCK
CAUTION!
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 continues to blow, it suggests a
problem in the circuit that must be corrected.
NOTE:If you are leaving your vehicle dormant for
longer than 21 days you may want to take steps to protect
your battery. You may do this by disconnecting the
battery or by disconnecting the two ignition-off draw
(I.O.D.) fuses located in the auxiliary Power Distribution
Center (PDC) in the engine compartment. The I.O.D.
cavities include a snap-in retainer that allows the fuse to
be disconnected without removing it from the fuse block.
Pressing the I.O.D. fuse back into the cavity reconnects it.

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 (I.O.D.) fuses located
in the Power Distribution Center (PDC). The I.O.D.
cavity includes a snap-in retainer that allows the fuse
to be disconnected without removing it from the fuse
block.
²The 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 cable from the battery.
