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 atmospheric
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 the following 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.
