The spotlights (with the switch in
the DOOR position) also come on
when you unlock the door with the
key or the remote transmitter, and
when you remove the key from the
ignition switch.
The spotlights have a two-position
switch. In the DOOR position, the
lights come on when you open any
door. The lights fade out in about 30
seconds after the doors are closed
tightly. In the OFF position, the
lights do not come on.
Your vehicle also has a courtesy light
in the ignition switch. This light
comes on when you open the driver’s
door. It fades out in about 30
seconds after the door is closed.
The courtesy light in each door
comes on when the door is opened,
and goes out when the door is closed.
