GETTING TO KNOW YOUR VEHICLE 17

If your vehicle is equipped with a “Rain Sensitive Wiper
System” and it is activated, the headlights will automati-
cally turn on after the wipers complete five wipe cycles
within approximately one minute, and they will turn off
approximately four minutes after the wipers completely
stop. Refer to “Windshield Wipers And Washers” in this
section for further information.
NOTE:When your headlights come on during the day-
time, the instrument panel lights will automatically dim to
the lower nighttime intensity.
Headlight Delay
To aid in your exit, your vehicle is equipped with a
headlight delay that will leave the headlights on for
approximately up to 90 seconds. This delay is initiated
when the ignition is turned OFF while the headlight switch
is on, and then the headlight switch is cycled off. Headlight
delay can be cancelled by either turning the headlight
switch on then off, or by turning the ignition ON.
NOTE: This feature can be programmed through the
Uconnect system. Refer to “Uconnect Settings” in “Multi-
media” for further information.
Lights-On Reminder
If the headlights, parking lights or cargo lights are left on
after the ignition is turned OFF, a chime will sound when
the driver ’s door is opened.
Daytime Running Lights — If Equipped
The Daytime Running Lights (low intensity) come on
whenever the engine is running, and the transmission is
not in the PARK position. The lights will remain on until
the ignition is switched to the OFF or ACC position or the
parking brake is engaged.
NOTE:
• If a turn signal is activated, the DRL lamp on the same
side of the vehicle will turn off for the duration of the
turn signal activation. Once the turn signal is no longer
active, the DRL lamp will illuminate.
• The DRL function may be disabled through the
Uconnect system. Refer to “Uconnect Settings” in “Mul-
timedia” for further information.
The headlight switch must be used for normal nighttime
driving.

Ambient Light — If Equipped
The overhead console is equipped with an ambient light
feature. This light casts illumination for improved visibility
of the floor and center console area.
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. For information on the rear
wiper/washer, refer to “Rear Window Wiper/Washer” in
this section.

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, push on the end of the lever (toward the
steering wheel) and hold while spray is desired. If the lever
is pushed while in the intermittent setting, the wipers will
turn on and operate for several wipe cycles after the end of
the lever is released, and then resume the intermittent
interval previously selected. If the end of the lever is pushed while the wipers are in the
off position, the wipers will operate for several wipe cycles,
then turn off.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
Use the Mist feature when weather conditions make occa-
sional usage of the wipers necessary. Rotate the end of the
lever downward 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 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
windshield washers of the vehicle ahead. Rotate the end of
the multifunction lever to one of four settings 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 position four is the most sensi-
tive. Setting three should be used for normal rain condi-
tions. Settings one and two can be used if the driver desires
less wiper sensitivity. Setting four can be used if the driver
desires more sensitivity. Place the wiper switch in the 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.

switch, the wipers will resume the continuous rear wiper
operation. When this rotary control is in the OFF position,
rotating it downward will activate the rear washer pump
which will continue to operate as long as the switch is held.
Once the switch is released it will return to the OFF
position and the wipers will cycle several times before
returning to the parked position.
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 rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the “park”
position.HEADLIGHT WASHERS — IF EQUIPPED
The multifunction lever operates the headlight washers
when the ignition switch is in the ON position and the
headlights are turned on. The multifunction lever is located
on the left side of the steering column.
To use the headlight washers, push the multifunction lever
inward (toward the steering column) and release it. The
headlight washers will spray a timed high-pressure spray
of washer fluid onto each headlight lens. In addition, the
windshield washers will spray the windshield and the
windshield wipers will cycle.
NOTE: After turning the ignition switch and headlights
ON, the headlight washers will operate on the first spray of
the windshield washer and then every eleventh spray after
that.

Rain Brake Support (RBS)
Rain Brake Support may improve braking performance in
wet conditions. It will periodically apply a small amount of
brake pressure to remove any water buildup on the front
brake rotors. It functions when the windshield wipers are
in LO or HI speed. When Rain Brake Support is active,
there is no notification to the driver and no driver interac-
tion is required.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the ESC and
Electric Power Steering (EPS) modules that provides
torque at the steering wheel for certain driving conditions
in which the ESC module is detecting vehicle instability.
The torque that the steering wheel receives is only meant to
help the driver realize optimal steering behavior in order to
reach/maintain vehicle stability. The only notification the
driver receives that the feature is active is the torque
applied to the steering wheel.NOTE:
The DST feature is only meant to help the driver
realize the correct course of action through small torques
on the steering wheel, which means the effectiveness of the
DST feature is highly dependent on the drivers sensitivity
and overall reaction to the applied torque. It is very
important to realize that this feature will not steer the
vehicle, meaning the driver is still responsible for steering
the vehicle.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off road driving while in
4WD Low Range. HDC maintains vehicle speed while
descending hills during various driving situations. HDC
controls vehicle speed by actively controlling the brakes.
HDC has three states:
1. Off (feature is not enabled and will not activate).
2. Enabled (feature is enabled and ready but activation conditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling ve- hicle speed).
190 SAFETY

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.
The wiper blades and wiper arms should be inspected
periodically, not just when wiper performance problems
are experienced. This inspection should include the follow-
ing 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.
