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 #27 in the Intelligent Power Module
labeled Ignition-Off Draw (IOD#1).
•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.

If a bulb needs to be replaced, visit your authorized

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.
WARNING!
A transient high tension 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.
