These lamps and the interior courtesy lamps will come
on when you open a door, and turn off when you turn
the ignition on. To turn on the reading lamps when the
doors are closed, press the button behind the lamp you
want on. Press it again to turn the lamp off.

When you open the trunk to its full open position, a
lamp will come on inside the trunk. This lamp will
automatically turn off when the trunk is closed.

This feature automatically shuts off the interior lamps if
any are left on for more than 10 minutes when the
ignition is off. This will keep your battery from 
running down.

This feature also shuts off the exterior lamps if they are
left on for more than 10 minutes when the ignition is off.
You may override this feature for the exterior lamps by
turning the lamps off and then back on after the ignition
is turned to off. If you do this, the exterior lamps will
stay on until you manually turn them off.

If the feature is enabled for the interior and exterior
lamps, all lamps should turn off at approximately the
same time.
