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.4 — Inner Park Light Bulb

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.
1. Open the hood.NOTE:Removal of the air cleaner filter housing may be
necessary prior to replacing bulbs in the headlight assem-
bly on the driver side of the vehicle.
2. Twist the appropriate bulb and socket assembly
counter-clockwise, and then pull it out of the headlight
assembly.
