The front courtesy overhead console and door courtesy
lights will not turn off if the dimmer control is in the
“Dome ON” position (rotate vertical thumb wheel all the
way to the top detent).
The illuminated entry system will not operate if the
dimmer control is in the “Dome OFF” position (rotate
vertical thumb wheel all the way to the bottom detent).
NOTE:If your vehicle is equipped with illuminated ap-
proach lights under the outside mirrors, they can be turned
off by moving the instrument panel dimmer into the
“Dome Defeat” detent position.
WINDSHIELD WIPERS AND WASHERS
Windshield Wipers
The wipers and washers are operated by a switch in the
multifunction lever. Turn the end of the lever to select the
desired wiper speed. 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 upward
to the first detent.
Windshield Wiper/Washer Switch

GETTING TO KNOW YOUR VEHICLE 79

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
80 GETTING TO KNOW YOUR VEHICLE

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 “Multi-
media” 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.
Position 3 should be used for normal rain conditions.
Positions 1 and 2 can be used if the driver desires less
wiper sensitivity. Positions 4 and 5 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 wind-
shield.
• 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).
• Transmission In NEUTRAL Position — When the igni-
tion is ON, and the transmission is in the NEUTRAL
position, the Rain Sensing system will not operate until
the wiper switch is moved, vehicle speed is greater than
5 mph (8 km/h), or the gear selector is moved out of the
NEUTRAL position.
• Remote Start Mode Inhibit — On vehicles equipped
with Remote Starting 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 RUN position, Rain Sensing
wiper operation can resume, if it has been selected, and
no other inhibit conditions (mentioned previously) exist.

If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode.
If the key fob is unavailable or the vehicle’s battery is
discharged, refer to “Gear Selector Override” in this section
for instructions on shifting the automatic transmission out
of PARK for towing.
CAUTION!
•Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheels OFFthe ground using a flatbed.
If flatbed equipment is not available, and the transmission
is operable, the vehicle may be towed (with the rear wheels
on the ground) under the following conditions:
• The transmission must be in NEUTRAL. •
The towing speed must not exceed 30 mph (48 km/h).
• The towing distance must not exceed 15 miles (24 km).
If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than 15
miles (24 km), tow with the rear wheels OFFthe ground.
Acceptable methods are to tow the vehicle on a flatbed, or
with the front wheels raised and the rear wheels on a
towing dolly, or (when using a suitable steering wheel
stabilizer to hold the front wheels in the straight position)
with rear wheels raised and the front wheels on the
ground.
CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe engine and/or transmission
damage. Damage from improper towing is not covered
under the New Vehicle Limited Warranty.
Four-Wheel Drive Models
The manufacturer recommends towing with all wheels
OFF the ground. Acceptable methods are to tow the vehicle
on a flatbed or with one end of vehicle raised and the
opposite end on a towing dolly.

IN CASE OF EMERGENCY 353

•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 applica-
tion 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 ser-
vices, 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 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 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.
