GENERAL INFORMATION
Condensation in Lamp Assemblies
Exterior lamps have vents to
accommodate normal changes in air
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 fine mist
can form on the interior of the lens. The
fine 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:
• The presence of a fine mist (no streaks,
drip marks or large droplets).
• A fine mist covers less than 50% of the
lens.
Examples of unacceptable condensation
are:
• A water puddle inside the lamp.
• Streaks, drip marks or large droplets
present on the interior of the lens.
If you see any unacceptable condensation,
have your vehicle checked by an authorized
dealer.
LIGHTING CONTROL
• Rotate the headlamp control clockwise
to the first position to turn on the
parking lamps, instrument panel lamps,
license plate lamps and tail lamps.
• Rotate clockwise to the second
position to also turn on the headlamps.
High Beams
Push the lever toward the instrument panel
to switch the high beams on.
Push the lever toward the instrument panel
again or pull the lever towards you to
