film of mist can form on the interior of the lens. The thin mist eventually
clears and exits through the vents during normal operation. Clearing
time may take as long as 48 hours under dry weather conditions.
Examples of acceptable condensation are:
•Presence of thin mist (no streaks, drip marks or droplets)
•Fine mist covers less than 50% of the lens
Examples of unacceptable moisture (usually caused by a lamp water
leak) are:
•Water puddle inside the lamp
•Large water droplets, drip marks or streaks present on the interior of
the lens
Take your vehicle to dealer for service if any of the above conditions of
unacceptable moisture are present.
Using the right bulbs
Replacement bulbs are specified in the following chart. Headlamp bulbs
must be marked with an authorized “D.O.T.” for North America and an
“E” for Europe to ensure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.

Note:To ensure a good seal, attach the bulb cover and partially tighten
the screws. Check to ensure the gasket is fully centered. Finish
tightening the screws in a criss-cross pattern (upper-left, lower right
etc.)
Replacing HID low beam headlamp bulbs (if equipped)
The low beam headlamps on your vehicle use a “high intensity discharge”
source. These lamps operate at a high voltage. When the bulb is burned
out, the bulb and starter capsule assembly must be replaced by your
authorized dealer.
Replacing front parking lamp/turn signal/sidemarker bulbs
The front parking lamp/turn signal/sidemarker bulbs are located in the
headlamp assembly. Follow the same steps to replace either bulb.

3. Remove three bolts, pull headlamp assembly forward and disconnect
the electrical connector.
4. Rotate the bulb socket
counterclockwise and remove from
lamp assembly.
5. Carefully pull bulb straight out of
the socket and push in the new bulb
until it snaps, locking it into
position.
6. To complete installation, follow
the removal procedure in reverse
order.
