Lights

Interior lighting battery saver

The interior lamps will automatically extinguish after 10 minutes when
the ignition key is in the off/lock position, a door has been left open or
the interior lamp controls are in the on position.

BULB REPLACEMENT

Headlamp 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, 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 dealer for service if any of the above conditions of
unacceptable moisture are present.

Using the right bulbs

Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized "D.O.T." for North America and an
"E" for Europe to ensure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.
