Rear Courtesy/Reading Lamps
(If equipped)
Your vehicle may be equipped with a
courtesy/reading lamp located at the rear-center
of the headliner (roof). The right lamp is for the
right side passenger and the left lamp is for the
left side passenger.
Rear seat courtesy/reading lamps (optional)
With the lens in the flat position, the
courtesy/reading lamp will illuminate when any
door is opened or when the headlamp dimmer
knob is rotated to the courtesy lamp position.
With the lens in the rotated position and the key
in the ON or ACC position, the
courtesy/reading lamp will illuminate.
Cleaning the Interior Lamps
Your interior dome lamps and map lamps are
plastic and should be cleaned with a mild
detergent diluted in water. Rinse them with clear
water.
