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.
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.
Replacing Bulbs
Note: Before changing bulb, verify the corresponding fuse is not blown.
The low beam headlamps, high beam headlamps, front turn signals and
side marker lamps are located in the headlamp assembly and can be
replaced individually by removing the headlamp assembly as a unit.
Replacing Headlamp Bulbs
Note: 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.
