Wipe Parking
If the ignition is changed to STOPPING THE ENGINE/OFF mode while the wipers are on 1, 2, or INT, they will immediately stop.
If the windshield wiper lever is then moved to off before the driver door is opened or within 10 minutes, the wipers will restart and move to the base of the windshield.
If the ignition is changed to STOPPING THE ENGINE/OFF while the wipers are performing wipes due to windshield washing, the wipers continue to run until they reach the base of the windshield.
