Lights
The dome lamp will stay on if the
control is moved to the passenger
side position. When the control is in
the middle position, the lamp will
only come on when a door is
opened. If the control is moved to
the driver's side position, the lamp
will not come on at all.
With the control in the middle position, the dome lamp will illuminate
whenever a front door is opened. If either front door has been opened
from the outside, the lamp will remain on for 25 seconds after the door
is shut. If any other door has been opened from the inside, the lamp will
shut off immediately after the door is closed.
The map lamp controls (if
equipped) are located on the dome
lamp. Press the controls on either
side of each lens on each map lamp
to activate the lamps.
If equipped with a moon roof, the
map lamps are located on the moon
roof control panel. Press the
controls on either side of each map
lamp to activate the lamps.
