Lamp assembly condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin 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 a dealer for service if any of the above conditions of
unacceptable moisture are present.
Using the right bulbs
Replacement bulbs are specified in the chart below. 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.

4. Turn the bulb holder
counterclockwise and remove it.
5. Disconnect the electrical
connector.
WARNING:Handle a halogen headlamp bulb carefully and keep
out of children’s reach. Grasp the bulb only by its plastic base
and do not touch the glass. The oil from your hand could cause the
bulb to break the next time the headlamps are operated.
6. Reverse the procedure to install the new bulb.
Replacing HID 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 bulbs
1. Make sure the headlamp switch is in the off position, then open the
hood.
