360 SERVICING AND MAINTENANCE
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 switched 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 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
properly. See an authorized dealer for
service.
NOTE:
On vehicles equipped with (HID) headlamps,
when the headlamps are turned on, there is a
blue hue to the lamps. This diminishes and
becomes more white after approximately
10 seconds, as the system charges.
Halogen Headlamps — If Equipped
NOTE:
Lens fogging can occur under certain atmo-
spheric conditions. This will usually clear as
atmospheric conditions change to allow the
condensation to change back to vapor. Turning
the lamps on will usually accelerate the clearing
process.
See below steps to replace:
1. Open the hood.
2. Access the back of the headlamp.
3. The air filter housing must be removed.
4. The windshield washer reservoir may need
to be rotated out of the way by removing the
fastener.
5. Coolant reservoir (if equipped) will need to
be repositioned by removing the fasteners,
and moving the unit out of the way.
6. To access the low beam bulb you must
remove the rubber boot seal from backside
of the lamp housing.
Rubber Boot Seal
NOTE:
Ensure the rubber boot is properly reinstalled to
prevent water and moisture from entering the
lamp.
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.
