78 GETTING TO KNOW YOUR VEHICLE
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 automati-
cally shut off.
NOTE:
The mist feature does not activate the washer pump; there -
fore, 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 automat -
ically activates the wipers for the driver. The feature is espe -
cially 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:
This feature can be programmed through the Uconnect
system. Refer to “Uconnect Settings” in “Multimedia” for
further information. 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 sensitive. Position 3
should be used for normal rain conditions. Positions 1 and 2
can be used if the driver desires less wiper sensitivity. Posi -
tions 4 and 5 can be used if the driver desires more sensi -
tivity. Place the wiper switch in the O (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 windshield.
• Use of Rain-X or products containing wax or silicone may reduce Rain Sensing performance.
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 operate until
the wiper switch is moved, vehicle speed is greater than
0 mph (0 km/h), or the outside temperature is greater than
32°F (0°C).
SERVICING AND MAINTENANCE 505
Checking Oil Level — Gas Engine
To assure proper lubrication of your vehicle's engine, 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. Always main-
tain the oil level within the SAFE zone on the dipstick.
Adding one quart of oil when the reading is at the bottom of
the SAFE zone will result in a reading at the top of the safe
zone on these engines.
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.
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 solu-
tion used with water as directed on the container, aids
cleaning action, reduces the freezing point to avoid line clog
-
ging, and is not harmful to paint or trim.
CAUTION!
Overfilling or underfilling will cause oil aeration or loss
of oil pressure. This could damage your engine.
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.

SERVICING AND MAINTENANCE 517
• Belt broken (note: identify and correct problem before newbelt 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 assure 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 Fall and Spring. Apply a small amount of a
high quality lubricant, such as Mopar Lock Cylinder Lubri
-
cant directly into the lock cylinder.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the wind -
shield 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 petro -
leum products such as engine oil, gasoline, etc.

518 SERVICING AND MAINTENANCE
NOTE:
Life expectancy of wiper blades varies depending on
geographical area and frequency of use. Poor performance 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 peri-
odically, 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. Wiper Blade Removal/Installation
1. Lift the wiper arm to raise the wiper blade off of the glass,
until the wiper arm is in the full up position.
Windshield Wiper ArmCAUTION!
Do not allow the wiper arm to spring back against the
glass without the wiper blade in place or the glass may
be damaged.
