section. For information on the rear wiper and washer,
refer to ªRear Window Featuresº in this section.
NOTE:Always remove any build-up of snow that
prevents the windshield wiper blades from returning to
the OFF position. If the windshield wiper switch isturned off and the blades cannot return to the OFF
position, damage to the wiper motor may occur.
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 seconds
after the lever is released, and then resume the intermit-
tent 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.

Mist
Use this feature when weather conditions make occa-
sional usage of the wipers necessary. Pull down and
release the control lever for a single wiping cycle.
Speed Sensitive Intermittent Wiper System
Use one of the five intermittent wiper speeds when
weather conditions make a single wiping cycle, with a
variable pause between cycles, desirable. Turn the end of
the lever to one of the five delay positions for the desired
delay interval. The delay can be regulated from a maxi-
mum of approximately 18 seconds between cycles, to a
cycle every 1/2 second.
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.
Rain Sensing WipersÐIf Equipped
This feature senses moisture on the windshield and
automatically activates the wipers for the driver. The
feature is especially useful for road splash or overspray
from the windshield washers of the vehicle ahead. Rotate
the end of the multi-function lever to one of five settings
to activate this feature.
The sensitivity of the system can be adjusted with the
multi-function lever. Wiper delay position 1 is the least
sensitive, and wiper delay position 5 is the most sensi-
tive. Setting 3 should be used for normal rain conditions.
Settings 1 and 2 can be used if the driver desires less
wiper sensitivity. Settings 4 and 5 can be used if the
driver desires more sensitivity. Place the wiper switch in
the OFF position when not using the system.
