■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 -
matically change to intermittent operation.* This will not happen if the interval
adjuster is set

to the lowest position.
*This feature can be deactivated. ( P. 3 8 4 )
■Windshield wiper features
●When the washer button is pressed with the wipers OFF, the wipers will make 3
sweeps, then pause, then a final sweep to completely clear the windshield*. The
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 -
light cleaners automatically operate once.
●The rear window and outside rear view mirror defoggers automatically turn on
when you operate the wipers.
