CHANGING A BULB

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.
Note: If the bulb is accidentally touched,
clean it with rubbing alcohol before
installing it.

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.
