to turn this feature on or off. Also, refer to ªWindshield
Wipers and Washersº in this section for more information
NOTE:When your headlights come on during the
daytime, the instrument panel lights will automatically
dim to the lower nighttime intensity. Refer to ªInstru-
ment Panel and Interior Lightsº below for setting the
instrument panel lights to full daytime intensity.
Instrument Panel and Interior Lights
When the multi-function control lever is in the parklight,
headlights, or AUTO position (if equipped), rotating the
center portion of the lever up and down will increase and
decrease the brightness (dimmer control) of the instru-
ment panel lights. Full daytime brightness on all elec-
tronic displays (odometer, overhead console, radio, and
Automatic Climate Control (if equipped) is obtained by
rotating the center portion of the control to the first
detent above the dimmer range. Rotating the control to
the second detent above the dimmer range turns theinterior lights on. Rotating the control to the ªOffº
(extreme bottom) position disables all the interior lights,
even when the doors and liftgate are open. While in the
ªOffº position the instrument panel lighting is at the
lowest light level and may not be suitable for night
driving.
Daytime Running Lights Ð Canada Only
The headlights come on at a low intensity level whenever
the engine is running. The lights remain on until the
ignition switch is turned OFF or the parking brake is
engaged. The headlight switch must be used for normal
night time driving.
Lights-On Reminder
If the headlights or parking lights are on after the ignition
is turned OFF, a chime will sound when the driver's door
is opened.

Headlight Time Delay
There is also a feature that delays turning off the vehicle
lights for 30, 60, or 90 seconds after the ignition switch is
turned OFF. To activate the headlight delay, the multi-
function control lever must be rotated to the ªOffº
position after the ignition switch is turned OFF. Only the
headlights will illuminate during this time. See ªOver-
head Consoleº in this section to turn this feature ªOn/
Offº or set the time interval.
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 ªLo,º ªHi,º or one of the five speed
sensitive intermittent windshield wiper speeds. Refer to
ªSpeed Sensitive Intermittent Wiper Systemº in this
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 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
80 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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 Sensitive Wiper System Ð If Equipped
The rain sensitive wiper system provides you with the
convenience of automatically detecting moisture on your
windshield and turning on the wipers at the appropriate
speed. The Rain Sensor is located above the rear view
mirror and reacts to any moisture present in the area of
the sensor.To activate the rain sensitive wiper system, turn the front
wiper control lever to AUTO. When you turn the lever to
AUTO, the wipers will operate a single wipe cycle. The
wipers will also cycle once when you start the vehicle if
the lever was left in AUTO.
There are five AUTO positions on the lever to allow you
to select system sensitivity that best suits you. The lowest
position (closest to OFF) is the least sensitive to rain and
the highest position is the most sensitive. If you select a
low sensitivity position on the control lever, the system
will be slower to react to rain and wipe only after some
rain accumulates on the windshield. If you select a high
sensitivity position, the system will be very quick to react
to rain drops and will wipe more often. If it is raining
steadily, the wipers will wipe continuously regardless of
what sensitivity the lever is. If the rain is heavy, the
wipers will operate in high speed. Every time you move
the lever to a higher sensitivity, the wipers will immedi-
ately operate a single wipe cycle.
82 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:Since the rain sensor is designed to detect
moisture, road spray, smashed bugs, and moisture from
passing trucks may occasionally cause the wipers to cycle
if the lever is in AUTO. Also, manual intervention may be
necessary under certain conditions: Additional wipes
may be desired, in foggy/misty mornings, where con-
densation builds up very slowly on the windshield, or
when water accumulated on the roof of the vehicle runs
down the windshield, but not over the sensor.
Fewer wipes and/or washer fluid may be desired when
salty road spray is encountered, where the operator may
want to turn the ªAutoº feature off and use the ªWashº
and/or ªMistº functions.CAUTION!
Turn the wiper lever to the OFF position to avoid
wiper damage when driving through an automatic
car wash.
WARNING!
Turn the wiper lever to the OFF position when
cleaning your windshield to avoid injury.

off until the engine warms up. However, the fan will
engage immediately if the defrost mode is selected or if
you select a fixed blower speed.
Window Fogging
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, use the A/C,
panel, and blower controls. Direct the panel outlets
toward the side windows. Recirculate without A/C
should not be used for long periods as fogging may
occur. Interior fogging on the windshield can be quickly
removed by using the defrost mode.
REAR WINDOW FEATURES
Rear Window Wiper/Washer
A switch on the right side of the steering column controls
operation of the rear wiper/washer function. Rotating
the center of the switch up to the DEL (Delay) position or
the ON position will activate the wiper. Push the lever
forward to initiate the wash function in any of the threepositions. The wash pump will continue to operate as
long as the button is pressed. Upon release, the wipers
will cycle three times before returning to the set position.
If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the ªParkº
position.

attention should also be given to hood latching compo-
nents to insure proper function. When performing other
underhood services, the hood latch, release mechanism
and safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the fall and spring. Apply a small
amount of a high quality lubricant such as MopartLock
Cylinder Lubricant directly into the lock cylinder.
Windshield Wiper Blades
The rubber edges of the wiper blades and the windshield
should be cleaned 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.
Windshield Washers Ð Front and Rear
On vehicles equipped with a Vehicle Information Center,
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 ªWasher Fluid
Lowº message will be displayed.
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fill
the reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.
