NOTE: The wiper delay times depend on vehicle speed.
If the vehicle is moving less than 10 mph (16 km/h),
delay times will be doubled.
Windshield Washer Operation
To use the washer, pull the lever toward you and hold
while spray is desired. If the lever is pulled while in the
delay range, the wiper will operate for several wipe
cycles after the lever is released, and then resume the
intermittent interval previously selected.
If the lever is pulled while in the off position, the wipers
will operate for several wipe cycles, then turn off.
WARNING!
Sudden loss of visibility through the windshield
could lead to an accident. You might not see other
vehicles or other obstacles. To avoid sudden icing of
the windshield during freezing weather, warm the
windshield with the defroster before and during
windshield washer use.
