ILLUMINATED ENTRY
The courtesy lights will turn on when you use the
key fob to unlock the doors or open any door.
This feature also turns on the approach lamps
located beneath the outside mirrors (if
equipped).
The lights will fade to off after approximately
30 seconds, or they will immediately fade to off
once the ignition switch is placed in the ON/
RUN position from the OFF position.
The front courtesy overhead console and door
courtesy lights will not turn off if the Dome ON
button on the overhead console is pushed. The
overhead and door courtesy lights will turn off
after 10 minutes to protect the battery. The illuminated entry system will not operate if
the Dome Defeat button on the overhead
console is pushed.
NOTE:
If your vehicle is equipped with Illuminated
Approach lights under the outside mirrors, they
will also be turned off by pushing the Dome
Defeat button.
WINDSHIELD WIPERS AND WASHERS
The windshield wiper/washer controls are
located on the multifunction lever on the left
side of the steering column. The front wipers are
operated by rotating a switch, located on the
end of the lever.

Windshield Wiper/Washer Lever

WINDSHIELD WIPER OPERATION
Intermittent Wipers
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 maximum
delay between cycles, rotate the control knob
upward to the first detent.
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 and hold. Washer fluid will be
sprayed and the wiper will operate for two to
three cycles after the washer knob is released.
If the washer knob pushed 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

21_DT_OM_EN_USC_t.book Page 58

GETTING TO KNOW YOUR VEHICLE59
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.
Mist
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 briefly 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.
For information on wiper care and replacement,
see Ú
page 418.
RAIN SENSING WIPERS — IF EQUIPPED
This feature senses rain or snowfall on the
windshield and automatically activates the
wipers. Rotate the end of the multifunction
lever to one of four detent positions to activate
this feature.
The sensitivity of the system can be adjusted
with the multifunction lever. Wiper delay
position one is the least sensitive, and wiper
delay detent position four is the most sensitive.
Wiper delay position three should be used for
normal rain conditions.
Positions one and two can be used if the driver
desires less wiper sensitivity. Position four can
be used if the driver desires more sensitivity.
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 perfor
-
mance.
The Rain Sensing feature can be turned on
and off using the Uconnect system
Ú page 237.
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 igni-
tion is first placed in the ON position, the Rain
Sensing system will not operate until the
wiper switch is moved, vehicle speed is
greater than 3 mph (5 km/h), or the outside
temperature is greater than 32°F (0°C).
WARNING!
Sudden loss of visibility through the wind -
shield 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.

408SERVICING AND MAINTENANCE
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 cross -
hatch markings on the dipstick. Adding 1 quart (1.0 liter) 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:
It is possible for your oil level to be slightly
higher than a previous check. This would be due
to diesel fuel that may temporarily be in the
crankcase due to operation of the diesel partic
-
ulate filter regeneration strategy (if equipped).
This fuel will evaporate out under normal oper -
ation.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 antifreeze).
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 solution
used with water as directed on the container,
aids cleaning action, reduces the freezing point
to avoid line clogging, and is not harmful to
paint or trim.
CAUTION!
Overfilling or underfilling the crankcase 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.

418SERVICING AND MAINTENANCE

Accessory Belt (Serpentine Belt)

Conditions that would require replacement:
Rib chunking (one or more ribs has sepa -
rated from belt body)
Rib or belt wear
Longitudinal belt cracking (cracks between
two ribs)
Belt slips
“Groove jumping" (belt does not maintain
correct position on pulley)
Belt broken
Noise (objectionable squeal, squeak, or
rumble is heard or felt while drive belt is in
operation) NOTE:
Identify and correct problem before new belt is
installed.
NOTE:
If your vehicle is equipped with a Stop/Start,
belt must be replaced with an OEM grade
Mopar belt.
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. Use 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 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.
