CHANGING A BULB

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.

These are examples of acceptable condensation:
• Presence of thin mist (no streaks, drip marks or droplets).
• Fine mist covers less than 50% of the lens.
These are examples of unacceptable moisture (usually caused by a lamp
water leak):
• 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.

Replacing Headlamp Bulbs

WARNING: Handle a halogen headlamp bulb carefully and keep
out of children’s reach. Grasp the bulb by only 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, it should be cleaned with
rubbing alcohol before being used.
