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.
Battery Saver
When the ignition is turned off, the vehicle will
turn off battery voltage to the interior lights
after 40 minutes.
This will prevent draining of the battery if those
lights have been left on inadvertently or if a
door is not completely closed. Battery voltage to
these lamps will be restored when the outside
front door handles are lifted, the keyless entry
keypad is used, the remote entry transmitter is
used, any door is opened, the trunk is opened,
or the ignition key is turned to the ON position.
