■Intermittent operation features
The time interval between sweeps decreases as vehicle speed increases. When
v
ehicle speed exceeds 12 mph (20 km/h) with the interval adjusted in the lowest
position, the time interval is set to the minimum 1.5 seconds.
If you stop the vehicle with the wiper switch in the “LO” position, the wipers auto -

adjuster is set

to the lowest position.
*This feature can be deactivated. ( P. 3 8 4 )

length of the pause will depend on the vehicle speed. The last sweep will not
happen if the vehicle is traveling above 106 mph (170 km/h).
*The last single sweep can be deactivated. ( P. 3 8 4 )
●When the windshield washer switch is pushed with the headlights on, the head -
