Automatic Headlight System — If Equipped
Turn the end of the multifunction lever to the third detent
to activate the automatic headlight system.
This system performs two functions. With the engine
running and the multifunction lever in the AUTO posi-
tion, the headlights will turn on and off based on the
surrounding light levels.
Headlights On Automatically With Wipers
If your vehicle is equipped with Automatic Headlights, it
also has this customer programmable feature. When your
headlights are in the automatic mode and the engine is
running, they will automatically turn on when the wiper
system is on.If your vehicle is equipped with a “Rain Sensitive Wiper
System” and it is activated, the headlights will automati-
cally turn on after the wipers complete five wipe cycles
within approximately one minute, and they will turn off
approximately four minutes after the wipers completely
stop. Refer to “Windshield Wipers and Washers” in this
section.
NOTE:When your headlights come on during the
daytime, the instrument panel lights will automatically
dim to the lower nighttime intensity. Refer to “Instru-
ment Panel and Interior Lights” for setting the instru-
ment panel lights to full daytime intensity.

WINDSHIELD WIPERS AND WASHERS
The front and rear wipers and washers are operated by a
switch in the right side control lever. Turn the end of the
control lever to select Low, High, or one of the five speed
sensitive intermittent windshield wiper speeds. Refer to
“Speed Sensitive Intermittent Wiper System” in this
section. For information on the rear wiper and washer,
refer to “Rear Window Features” in this section.
NOTE:Always remove any buildup of snow that pre-
vents the windshield wiper blades from returning to the
off position. If the windshield wiper switch is turned 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 the Mist feature when weather conditions make
occasional 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 Wipers — If 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 multifunction lever to one of five settings
to activate this feature.
The sensitivity of the system can be adjusted with the
multifunction 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.
NOTE:
•The rain sensing feature will not operate when the
wiper switch is in the Low or High speed position.
•The rain sensing feature may not function properly
when ice, or dried salt water is present on the wind-
shield.
•Use of Rain-Xor products containing wax or silicone
may reduce rain sensor performance.
•A customer programmable feature in the Electronic
Vehicle Information Center (EVIC) allows the Rain
Sense feature to be turned off. Refer to “Electronic
Vehicle Information Center (EVIC) — Customer-
Programmable Features” in Section 4 of this manual.
The rain sensing system has protection features for the
wiper blades and arms, and will not operate under the
following conditions:
•Low Ambient Temperature— When the ignition is
first turned ON, the rain sensing system will not

Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild nonabrasive cleaner to remove accumulations of salt
or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.
Avoid using the wiper blades to wipe frost or ice from the
windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
Adding Washer Fluid
On vehicles equipped with a Electronic Vehicle Informa-
tion Center (EVIC), the low washer fluid level will be
indicated. When the sensor detects a low fluid level, the
windshield will light on the vehicle graphic outline and
the “WASHER FLUID LOW” message will be displayed.The fluid reservoir for the windshield washers and the
rear window washer is shared. The fluid reservoir is
located in the engine compartment, be sure to check the
fluid level at regular intervals. Fill the reservoir with
windshield washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take some
washer fluid and apply it to a cloth or towel and wipe
clean the wiper blades, this will help blade performance.
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.
