Windshield Wiper Operation
Rotate the end of the lever upward, to the first detent past
the 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 opera-
tion.
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 maxi-
mum delay between cycles, rotate the control knob into the
upper end of the delay range.
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
approximately 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 wind-
shield during freezing weather, warm the windshield
with the defroster before and during windshield
washer use.
Mist Feature
When a single wipe to clear off road mist or spray from a
passing vehicle is needed, push the washer knob, located
on the end of the multifunction lever, inward to the first
detent and release. The wipers will cycle one time and
automatically shut off.
NOTE:The mist feature does not activate the washer
pump; therefore, no washer fluid will be sprayed on the
windshield. The wash function must be used in order to
spray the windshield with washer fluid.
Rain Sensing Wipers — If Equipped
This feature senses moisture on the windshield and auto-
matically 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.
NOTE: If your vehicle is equipped with a touchscreen, this
feature can be programmed through the Uconnect system.
Refer to “Uconnect Settings” in “Understanding Your
Instrument Panel” for further information.
If your vehicle is not equipped with a touchscreen, this
feature can be programmed through the instrument cluster
display. Refer to “Instrument Cluster Display” in “Under-
standing Your Instrument Panel” for further information.
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 sensitive.
Setting 3 should be used for normal rain conditions.
Settings 1 and 2 can be used if the driver desires less wiper
sensitivity. Setting 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.

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. This will 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 remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor perfor-
mance of blades may be present with chattering, marks,
water lines or wet spots. If any of these conditions are
present, clean the wiper blades or replace as necessary. The wiper blades and wiper arms should be inspected
periodically, not just when wiper performance problems
are experienced. This inspection should include the follow-
ing points:
•
Wear Or Uneven Edges
• Foreign Material
• Hardening Or Cracking
• Deformation Or Fatigue
If a wiper blade or wiper arm is damaged, replace the
affected wiper arm or blade with a new unit. Do not
attempt to repair a wiper arm or blade that is damaged.
Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back against the
glass without the wiper blade in place or the glass may
be damaged.
466 MAINTAINING YOUR VEHICLE
Installing The Front Wipers
1. Lift the wiper arm off of the glass, until the wiper arm isin the full up position.
2. Position the wiper blade under the hook on the tip of the wiper arm with the wiper locking tab open.
3. Insert the receiver bracket on the wiper assembly into the hook on the tip of the arm through the opening in
the wiper blade under the locking tab.
4. Slide the wiper blade up into the hook on the wiper arm until it is latched (engagement will be accompanied by
an audible click). Fold down the latch release tab and
snap it into its locked position.
5. Gently lower the wiper blade onto the glass.
Adding Washer Fluid
The fluid reservoir is located under the hood and should be
checked for fluid level at regular intervals. Fill the reservoir
with windshield washer solvent only (not radiator anti-
freeze). When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or towel and wipe
the wiper blades clean. 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.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around the
washer solution.
After the engine has warmed up, operate the defroster for
a few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. Windshield
washer solution used with water as directed on the con-
tainer, aids cleaning action, reduces the freezing point to
avoid line clogging, and is not harmful to paint or trim.
Exhaust System
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
