The wiper lever must be in the INTº position.
The time interval between sweeps is shortened when the

the full upward position, the time interval becomes the shortest
1.5 seconds.
If you stop the vehicle with the wiper switch in the LOº position,

If the wiper lever is in the OFFº position, the wipers will
automatically make 3 wipes and then a single wipe later to
sweep the windshield completely.* The interval between the

last sweep does not happen if the vehicle speed exceeds about
170 km/h (106 mph).
NOTE:
* The last single wipe can be deactivated.
