vent the battery from being dis-
charged. The system automatically
turns off the parking lamps when the

will turn off automatically if the driver
parks on the side of the road at night.
If necessary, to keep the lamps on
when the engine is turned off, per-
form the following:
1) Open the driver-side door.
2) Turn the parking lamps OFF and
ON again using the light switch on
the steering column.

(if equipped)
If you place the ignition switch in to
the ACC or OFF position with the

play.For more details, refer to

through other doors (except the
driver's door), the battery saver
function does not operate and the
