Lights
Cargo/reading lamps
The dome portion of the lamp or
the center light can be turned on
when the panel dimmer control is
rotated fully up or when a door is
opened.
The rear dome lamp can be turned
ON or OFF by sliding the control.
BULB REPLACEMENT
Headlamp Condensation
The headlamps are vented to equalize pressure. When moist air enters
the headlamp(s) through the vents, there is a possibility that
condensation can occur. This condensation is normal and will clear
within 45 minutes of headlamp operation.
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. Using incorrect bulbs may damage the lamp assembly
or void the lamp assembly warranty or may not provide quality bulb burn
time.
