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
flashers.
This is an emergency warning system and should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning lights will continue to operate even
though the ignition switch is OFF.
NOTE:With extended use, the Hazard Warning lights
may discharge your battery.

470 MAINTAINING YOUR VEHICLE

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 over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.
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.
472 MAINTAINING YOUR VEHICLE

•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.
