Intermittent Wiper System
Use one of the four intermittent wiper settings when
weather conditions make a single wiping cycle, with a
variable delay between cycles, desirable. At driving
speeds above 10 mph (16 km/h), the delay can be
regulated from a maximum of approximately 18 seconds
between cycles (first detent), to a cycle every one second
(fourth detent).
NOTE: If the vehicle is moving less than 10 mph
(16 km/h), delay times will be doubled.
