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 (Aerodynamic)

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.

Note: If the bulb is accidentally touched, it should be cleaned with

alcohol before being used.

1. Make sure the headlamp switch is in the off position, then open the

hood.
