22GETTING TO KNOW YOUR VEHICLE
Additional features, such as windshield
wipers, will also not be available while the
vehicle is in the Remote Start mode.
The engine can be started two consecutive
times (two 15 minute cycles) with the key
fob. However, the ignition switch must be
placed in the ON/RUN position before you
can repeat the start sequence for a third
cycle.
To Exit Remote Start Mode Without Driving
The Vehicle
Push and release the Remote Start button one
time or allow the engine to run for the entire
15 minute cycle.
NOTE:
To avoid unintentional shut downs, the system
will disable for two seconds after receiving a
valid Remote Start request.
To Exit Remote Start Mode And Drive The
Vehicle
To exit Remote Start Mode and drive the vehicle
before the end of the 15 minute cycle, push and
release the unlock button on the key fob to
unlock the door and disarm the vehicle security alarm System (if equipped). Then, prior to the
end of the 15 minute cycle, place the ignition in
the ON/RUN position.
NOTE:
The ignition switch must be in the ON/RUN posi
-
tion in order to drive the vehicle.
Remote Start Comfort Systems — If
Equipped
When remote start is activated, the heated
steering wheel, and driver heated seat features
will automatically turn on in cold weather. In
warm weather, the driver vented seat feature
will automatically turn on when the remote start
is activated. These features will stay on through
the duration of remote start or until the ignition
switch is placed in the ON/RUN position.
NOTE:
The Remote Start Comfort System can be acti -
vated and deactivated through the Uconnect
System. Refer to “Uconnect Settings” in “Multi -
media” for further information on Remote Start
Comfort System operation.
SENTRY KEY
The Sentry Key Immobilizer system prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed
or activated. Operation is automatic, regardless
of whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button
ignition and a Radio Frequency (RF) receiver to
prevent unauthorized vehicle operation. There -
fore, only key fobs that are programmed to the
vehicle can be used to start and operate the
vehicle. The system cannot reprogram a key fob
obtained from another vehicle.
After placing the ignition switch in the ON/RUN
position, the vehicle security light will turn on for
three seconds for a bulb check. If the light
remains on after the bulb check, it indicates
that there is a problem with the electronics. In
addition, if the light begins to flash after the
bulb check, it indicates that someone
attempted to start the engine with an invalid key
fob. In the event that a valid key fob is used to
start the engine but there is an issue with the
vehicle electronics, the engine will start and
shut off after two seconds.

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.

Windshield Wiper/Washer Switch

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 oper -
ation.
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 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 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 previ
-
ously 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.
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.
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.

GETTING TO KNOW YOUR VEHICLE51
Rain Sensing Wipers — If Equipped
This feature senses moisture on the windshield
and automatically 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:
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 multifunction lever. Wiper delay posi -
tion 1 is the least sensitive, and wiper delay
position 5 is the most sensitive. Position 3
should be used for normal rain conditions. Posi -
tions 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 windshield.
Use of Rain-X or products containing wax or
silicone may reduce Rain Sensing perfor
-
mance.
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 0 mph (0 km/h), or the outside
temperature is greater than 32°F (0°C).
Transmission In NEUTRAL Position — When
the ignition 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 condi -
tions (mentioned previously) exist.
CLIMATE CONTROLS
The Climate Control system allows you to regu -
late the temperature, air flow, and direction of
air circulating throughout the vehicle. The
controls are located on the touchscreen (if
equipped), on the sides of the touchscreen, or
on the instrument panel below the radio.

SERVICING AND MAINTENANCE345
Checking Oil Level — Gas Engine
To ensure 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 maintain 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.
Checking Oil Level — Diesel Engine
To ensure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. Check the oil level at regular
intervals. The best time to check the oil level is
before starting the engine after it has been parked overnight. When checking oil after oper
-
ating the engine, first ensure the engine is at full
operating temperature, then wait for
30 minutes after engine shutdown to check the
oil.

Engine Oil Dipstick

Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Add oil only when the level on the
dipstick is below the “ADD” mark. The total
capacity from the ADD mark to the Full mark is
2 Quarts (1.9Liters). Never operate the engine with oil level below
the “ADD” mark or above the upper “SAFE”
mark.
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.
CAUTION!
Overfilling or underfilling will cause oil
aeration or loss of oil pressure. This could
damage your engine.
1 — ADD Range
2 — Full Mark
3 — SAFE Range
CAUTION!
Overfilling or underfilling the crankcase will
cause oil aeration or loss of oil pressure. This
could damage your engine.

360SERVICING AND MAINTENANCE
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 Lubri -
cant 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 wind -
shield.
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 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 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.
