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 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 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 prop-
erly. See your authorized dealer for
service.NOTE:
On vehicles equipped with High Intensity
Discharge (HID) headlamps, when the head-
lamps 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:
We advise referring to an authorized dealer.
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. Turn-
ing the lamps on will usually accelerate the
clearing process.
1. Open the hood.
2. Access the back of the headlamp.NOTE:
• The air filter housing must be removed.
• The windshield washer reservoir may
need to be rotated out of the way by
removing the fastener.
• Coolant reservoir (if equipped) will
need to be repositioned by removing
the fasteners, and moving the unit out
of the way.
3. To access the low beam bulb you must
remove the rubber boot seal from back-
side of the lamp housing.
NOTE:
Ensure the rubber boot is properly rein-
stalled to prevent water and moisture from
entering the lamp.
CAUTION!
•Do not contaminate the bulb glass by
touching it with your fingers or by allow-
ing it to contact other oily surfaces.
Shortened bulb life will result.
IN CASE OF EMERGENCY
206

CAUTION!
• 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.
4. Turn the low or high beam bulb one–
quarter turn counterclockwise to remove
from housing.
5. Disconnect the electrical connector and
replace the bulb.

We advise referring to an authorized dealer.
1. Open the hood.
2. Access the back of the headlamp.NOTE:
• The air filter housing must be removed.
• The windshield washer reservoir may
need to be rotated out of the way by
removing the fastener.
• Coolant reservoir (if equipped) will
need to be repositioned by removing the
fasteners, and moving the unit out of
the way.
3. Turn the turn signal bulb one–quarter turn
counterclockwise to remove from housing.
4. Disconnect the electrical connector and
replace the bulb.
CAUTION!
Do not touch the new bulb with your fin-
