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:
²Remove fuse #27 in the Intelligent Power Module
labeled Ignition-Off Draw (IOD#1).
²Or, disconnect the negative cable from the battery.

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 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.

BULB REPLACEMENT
High Intensity Discharge Headlights (HID) Ð If
Equipped
The headlights are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlight switch off and the key removed.Because of
this, you should not attempt to service a headlight bulb
yourself. If a headlight bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high tension occurs at the bulb sockets of
High Intensity Discharge (HID) headlights when the
headlight 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 Headlights (HID), when the headlights are turned
on, there is a blue hue to the lights. This diminishes and
becomes more white after approximately 10 seconds, as
the system charges.
