&UnlockCAUTION!
•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 overload. If
a properly rated fuse continues to blow, it indicates
a problem in the circuit that must be corrected.

VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
•Remove fuse #J13 in the Totally Integrated Power
Module (TIPM) labeled Main Ignition-Off Draw (IOD).
•Or, disconnect the negative cable from the battery.
•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
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.

BULB REPLACEMENT
High Intensity Discharge Headlamps (HID) – If
Equipped
The headlamps are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlamp switch off and the key removed.Because of this,
you should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your vehicle to an
authorized dealer for service.7
MAINTAINING YOUR VEHICLE 653

WARNING!
A transient high voltage occurs at the bulb sockets of
High Intensity Discharge (HID) headlamps when the
headlamp switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.
NOTE:On vehicles equipped with High Intensity Dis-
charge (HID) headlamps , when the headlamps are
turned on, there is a blue hue to the lamps. This dimin-
ishes and becomes more white after approximately 10
seconds, as the system charges.
Halogen Headlamps – If Equipped
1. Open the hood.
2. Turn the low or high beam bulb one–quarter turn
counterclockwise to remove from housing.3. Disconnect the electrical connector and replace the
bulb.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.
Front Turn Signal
1. Open the hood.
2. Turn the turn signal bulb one–quarter turn counter-
clockwise to remove from housing.
3. Disconnect the electrical connector and replace the
bulb.
