CAUTION!
•When installing the totally integrated power mod-
ule cover, it is important to ensure the cover is
properly positioned and fully latched. Failure to
do so may allow water to get into the totally
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 (IOD) fuse located in
the Integrated Power Module, located in the engine
compartment. The IOD cavity includes a snap-in re-
tainer that allows the fuse to be disconnected without
removing it from the fuse block.
•As an alternative to the above steps you may discon-
nect the negative cables from both batteries.
•Any 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 minutes
in 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.7

8. Reach through the access hole of the wheel house
splash shield and lift the slide lock upward far enough to
disengage it from the lock post on the back of the front
lamp unit housing.
9. Remove the headlamp assembly. Grasp the outboard
edge of the lamp and pull it straight forward to disen-
gage the ball stud from the plastic grommet.10. Disconnect electrical connectors.
11. Replace bulb(s) as necessary.
CAUTION!
•Do not contaminate the bulb glass by touching it
with your fingers or by allowing it to contact other
oily surfaces. Shortened bulb life will result.
•Always use the correct bulb size and type for
replacement. An incorrect bulb size or type may
overheat and cause damage to the lamp, the bulb
socket, or the lamp wiring.
NOTE:There are access covers over both headlamp
bulb access holes in the quad front lamp unit housing (if
equipped). These covers MUST be reinstalled after the
bulb has been replaced.
448 MAINTAINING YOUR VEHICLE

Fog Lamps – If Equipped
1. Reach under and behind the front bumper to access
the back of the front fog lamp housing.
2. Disconnect the fog lamp wiring harness connector
from the fog lamp bulb.
3. Rotate the bulb counterclockwise
14turn to unlock the
bulb from the housing.
4. Pull the bulb straight out from the housing.
CAUTION!
Do not contaminate the bulb glass by touching it
with your fingers or by allowing it to contact other
oily surfaces. Shortened bulb life will result.
