System Description 22A-209

Intermittent operation:

Rear window wiper switch ON: The wiper operates every seven seconds after completing two sweeps.

Rear window wiper switch OFF: The wiper returns to the park position.


Washer/Wiper combined system:

Rear window wiper switch ON: The wiper operates continuously while the washer switch is ON.

Rear window wiper switch OFF: After switching OFF the washer switch, the wiper returns to the park position after completing two sweeps.

Failsafe Function:

Lock Function: The rear window wiper will not operate if the hatch glass is open.

Emergency Stop Function: If the hatch glass is opened while the rear window wiper is operating, it will automatically stop.

Automatic Park Function: If the ignition switch is turned OFF while the rear window wiper is operating, the wiper will return to the park position.

NOTE: To avoid interference with the vehicle's spare tire, the rear wiper does not fold out as on previous models.
