To use the washer, press the end of the multifunction
lever in when spray is desired, the washers will spray for
a maximum of 20 seconds or until the lever is released. If
another washer cycle is desired the end of the lever must
be pressed again to get another 20 second washer cycle. If
the lever is depressed while in the delay range, the
wipers will operate for several seconds after the lever is
released, and then resume the intermittent interval pre-
viously selected.
If the end of the lever is depressed while in the OFF
position, the wipers will operate for approximately two
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 defroster before and during wind-
shield washer use.
