WINDSHIELD WIPERS AND WASHERS
The windshield wiper/washer lever is located on
the right side of the steering column. The front
wipers are operated by rotating a switch, located
on the end of the lever.

Multifunction Lever

WINDSHIELD WIPER OPERATION
The wipers and washers are operated by a switch
within the wiper lever. Rotate the switch at the end
of the lever upward, to the first detent past the
intermittent settings for low-speed wiper
operation. Rotate the switch at the end of the lever
upward to the second detent past the intermittent
settings for high-speed wiper operation. To turn the
windshield wipers off, rotate the switch within the
lever all the way down to OFF.
Intermittent Wiper System
Use the intermittent wiper when weather
conditions make a single wiping cycle with a
variable pause between cycles desirable. Rotate
the switch at the end of the wiper lever to the first
detent position, and then turn the switch at the end
of the lever to select the desired delay interval.
There are four delay settings, which allow you to
regulate the wipe interval from a minimum of one cycle every second to a maximum of approximately
36 seconds between cycles. The delay intervals
will double in duration when the vehicle speed is
10 mph (16 km/h) or less.
NOTE:If the vehicle is moving less than 10 mph
(16 km/h), delay times will be doubled.
Windshield Washer Operation
To use the washer, pull the lever rearward toward
you and hold. If the lever is pulled while on the
intermittent setting, the wipers will turn on and
operate for several wipe cycles after the lever is
released, and then resume the intermittent
interval previously selected. If the lever is pulled
while the wipers are in the off position, the wipers
will operate several cycles, then turn off.
NOTE:
As a protective measure, the pump will stop if
the switch is held for more than 20 seconds.
Once the switch is released the pump will
resume normal operation.
If the front window washer feature is activated,
all of the front cameras (if equipped) on the
vehicle will be washed as well.
1 — Pull For Front Washer
2 — Rotate For Rear Wiper Operation
3 — Rotate For Front Wiper Operation
4 — Push Forward For Rear Washer
5 — Push Up For Mist
CAUTION!
Always remove any buildup of snow that
prevents the windshield wiper blades from
returning to the parked position. If the
windshield wiper switch is turned off, and the
blades cannot return to the parked position,
damage to the wiper motor may occur.

Mist
Use the Mist feature when weather conditions
make occasional usage of the wipers necessary.
Push the lever upward to the MIST position and
release for a single wiping cycle.
NOTE:The Mist feature does not activate the washer
pump; therefore, no washer fluid will be sprayed on
the windshield. The washer function must be used
in order to spray the windshield with washer fluid.
For information on wiper care and replacement,
see Úpage 343.
RAIN SENSING WIPERS — IF EQUIPPED
This feature senses rain or snowfall on the
windshield and automatically activates the wipers.
Rotate the end of the windshield wiper lever to one
of the four detent positions to activate this feature.
The sensitivity of the system is adjustable from the
windshield wiper lever. Wiper sensitivity position 1
is the least sensitive, and wiper sensitivity position
4 is the most sensitive.
NOTE:
The Rain Sensing feature will not operate when
the wiper switch is in the low, high, or OFF posi -
tion. Only in one of the intermittent positions.
The Rain Sensing feature may not function prop -
erly when ice or dried saltwater is present on the
windshield.
Use of products containing wax or silicone may
reduce rain sensor performance.
The Rain Sensing feature can be turned on and
off through the Uconnect system Ú page 204.The Rain Sensing system has protective features
for the wiper blades and arms. It will not operate
under the following conditions:
Low Temperature Wipe Inhibit
— The Rain
Sensing feature will not operate when the igni -
tion is first placed in the ON/RUN position, when
the vehicle is stationary and the outside
temperature is below 32°F (0°C), unless the
wiper control on the windshield wiper lever is
moved, the vehicle speed becomes greater than
3 mph (5 km/h) or the outside temperature
rises above freezing.
Neutral Wipe Inhibit — The Rain Sensing feature
will not operate when the ignition is placed in
the ON/RUN position, when the transmission
gear selector is in the NEUTRAL position and the
vehicle speed is less than 3 mph (5 km/h),
unless the wiper control on the windshield wiper
lever is moved, the vehicle speed is greater than
3 mph (5 km/h) or the gear selector is moved
out of the NEUTRAL position.
Remote Start Mode Inhibit — On vehicles
equipped with the Remote Start system, Rain
Sensing wipers are not operational when the
vehicle is in the Remote Start mode. Once the
operator is in the vehicle and has placed the
ignition switch in the ON/RUN position, rain
sensing wiper operation can resume, if it has
been selected, and no other inhibit conditions
(mentioned previously) exist.
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.

SERVICING AND MAINTENANCE337
CHECKING OIL LEVEL
To ensure proper engine lubrication, the engine oil
must be maintained at the correct level. Check the
oil level at regular intervals, such as every fuel
stop. The best time to check the engine oil level is
about five minutes after a fully warmed up engine
is shut off.
Checking the oil while the vehicle is on level ground
will improve the accuracy of the oil level readings.
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the low
end of the range and MAX at the high end of the
range.
Crosshatched zone marked with dimples at the
MIN and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 qt (1.0 L) of oil when the reading is at the
low end of the dipstick range will raise the oil level
to the high end of the range marking.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
NOTE:Use care when filling under hood fluids such as
engine oil, washer fluid, antifreeze, etc., to
minimize spillage onto the top of the engine. Any
excess fluid that is spilled onto the top of the
engine should be removed using compressed air
or an absorbent cloth.
ADDING WASHER FLUID
The instrument cluster display will indicate when
the washer fluid level is low. When the sensor
detects a low fluid level, the Low Washer Fluid
Warning Light will illuminate and the “Washer Fluid
Low” message will display.
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.
NOTE:Use care when filling under hood fluids such as
engine oil, washer fluid, antifreeze, etc., to
minimize spillage onto the top of the engine. Any
excess fluid that is spilled onto the top of the
engine should be removed using compressed air
or an absorbent cloth.
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.
CAUTION!
Do not travel with the windshield washer fluid
reservoir empty: the windshield washers are
essential for improving visibility.

SERVICING AND MAINTENANCE343
Belt broken (identify and correct problem before
new belt is installed)
Noise (objectionable squeal, squeak, or rumble
is heard or felt while drive belt is in operation)
Some conditions can be caused by a faulty
component such as a belt pulley. Belt pulleys
should be carefully inspected for damage and
proper alignment.
Belt replacement on some models requires the
use of special tools, we recommend having your
vehicle serviced at an authorized dealer.
BODY LUBRICATION
Locks and all body pivot points, including such
items as seat tracks, door hinge pivot points and
rollers, liftgate, tailgate, decklid, sliding doors and
hood hinges, should be lubricated periodically with
a lithium-based grease, such as Mopar® Spray
White Lube to ensure quiet, easy operation and to
protect against rust and wear. Prior to the
application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit;
after lubricating excess oil and grease should be
removed. Particular attention should also be given
to hood latching components to ensure 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 Autumn and Spring.
Apply a small amount of a high quality lubricant,
such as Mopar® Lock Cylinder Lubricant directly
into the lock cylinder.
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
performance of blades may be present with chat
-
tering, 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 following 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.
Front 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.
