WINDSHIELD WIPERS AND WASHERS
Windshield Wipers
The wipers and washers are operated by a switch in the
multifunction lever. Turn the end of the lever to select the
desired wiper speed.

intermittent settings for low-speed wiper operation. Rotate
the end of the lever upward to the second detent past the
intermittent settings for high-speed wiper operation.

GETTING TO KNOW YOUR VEHICLE 77
Intermittent Wiper System
The intermittent feature of this system was designed for use
when weather conditions make a single wiping cycle, with a
variable pause between cycles, desirable. For maximum
delay between cycles, rotate the control knob upward to the
first detent.
The delay interval decreases as you rotate the knob until it
enters the low continual speed position. The delay can be
regulated from a maximum of about 18 seconds between
cycles, to a cycle every one second. The delay intervals will
double in duration when the vehicle speed is 10 mph
(16 km/h) or less.
Windshield Washers
To use the windshield washer, push the washer knob,
located on the end of the multifunction lever, inward to the
second detent. Washer fluid will be sprayed and the wiper
will operate for two to three cycles after the washer knob is
released from this position.If the washer knob is depressed while in the delay range, the
wiper will operate for several seconds after the washer knob
is released. It will then resume the intermittent interval
previously selected. If the washer knob is pushed while in
the off position, the wiper will turn on and cycle approxi
-
mately three times after the wash knob is released.
To prevent freeze-up of your windshield washer system in
cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
WARNING!
Sudden loss of visibility through the windshield could
lead to a collision. 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.
