SAFETY191
To turn ESC on again, momentarily push the ESC
OFF button. This will restore the “ESC On” mode of
operation.
NOTE:The “ESC OFF” message will display and an audible
chime will sound when the gear selector is placed
into the PARK position from any other position, and
then moved out of the PARK position. This will
occur even if the message was previously cleared.
ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator
Light in the instrument cluster will come
on when the ignition is placed in the ON
mode. It should go out with the engine
running. If the ESC Activation/Malfunction
Indicator Light comes on continuously with the
engine running, a malfunction has been detected
in the ESC system. If this light remains on after
several ignition cycles, and the vehicle has been driven several miles (km) at speeds greater than
30 mph (48 km/h), see an authorized dealer as
soon as possible to have the problem diagnosed
and corrected.
The ESC Activation/Malfunction Indicator Light
starts to flash as soon as the tires lose traction and
the ESC system becomes active. The ESC
Activation/Malfunction Indicator Light also flashes
when Traction Control System (TCS) is active. If the
ESC Activation/Malfunction Indicator Light begins
to flash during acceleration, ease up on the
accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the
prevailing road conditions.
The ESC OFF Indicator Light indicates the
customer has elected to have the
Electronic Stability Control (ESC) in a
reduced mode.
NOTE:
The ESC Activation/Malfunction Indicator Light
and the ESC OFF Indicator Light come on
momentarily each time the ignition is placed in
the ON/RUN position.
Each time the ignition is placed in the ON/RUN
position, the ESC system will be on even if it was
turned off previously.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive
following the maneuver that caused the ESC
activation.
Emergency Stop Signal (ESS) —
If Equipped
The ESS activates the hazard lights at a faster than
normal speed when heavy brake pressure is
applied. ESS will only activate when the speed is
above 31 mph (50 km/h). The ESS operates
independently of other lamps, and will turn on and
off automatically. This indicates to others that the
vehicle is stopping quickly.
NOTE:
A warning light will illuminate within the instru -
ment cluster to inform the driver that the ESS
feature has been activated.
When towing a trailer, ESS will also activate the
rear indicator lights of the trailer.
Hill Descent Control (HDC) — If Equipped
Hill Descent Control (HDC) is intended for low
speed off-road driving while in 4WD Low. HDC
maintains vehicle speed while descending hills
during various driving situations. HDC controls
vehicle speed by actively controlling the brakes.
WARNING!
In the "Full Off" mode, the engine torque
reduction and stability features are disabled. In
an emergency evasive maneuver, the ESC
system will not engage to assist in maintaining
stability. “Full Off” mode is intended for
off-highway or off-road use only.

SAFETY193
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a
complete stop while on an incline. If the driver
releases the brake while stopped on an incline,
HSA will continue to hold the brake pressure for a
short period. If the driver does not apply the
throttle before this time expires, the system will
release brake pressure and the vehicle will roll
down the hill as normal.
The following conditions must be met in order for
HSA to activate:
The feature must be enabled.
The vehicle must be stopped.
The parking brake must be off.
The driver’s door must be closed.
The vehicle must be on a sufficient grade.
The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in forward
gear; vehicle backing uphill is in REVERSE gear).
HSA will work in REVERSE gear and all forward
gears. The system will not activate if the trans -
mission is in PARK or NEUTRAL.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:
If disabling HSA using Uconnect settings see
Ú page 77.
Towing With HSA
Hill Start Assist (HSA) will also provide assistance
to mitigate roll back while towing a trailer.
Rain Brake Support (RBS)
RBS 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 interaction is required.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement.
It is always the driver’s responsibility to be
attentive to distance to other vehicles, people,
and objects, and most importantly brake
operation to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle. Failure to
follow these warnings can result in a collision or
serious personal injury.
WARNING!
If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there
may not be enough brake pressure to hold
both the vehicle and the trailer on a hill when
the brake pedal is released. In order to avoid
rolling down an incline while resuming accel -
eration, manually activate the trailer brake or
apply more vehicle brake pressure prior to
releasing the brake pedal.
HSA is not a parking brake. Always apply the
parking brake fully when exiting your vehicle.
Also, be certain to place the transmission
in PARK.
Failure to follow these warnings can result in a
collision or serious personal injury.

194SAFETY
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full
braking during emergency braking situations. It
anticipates when an emergency braking situation
may occur by monitoring how fast the throttle is
released by the driver. The Electronic Brake
Controller (EBC) system will prepare the brake
system for a panic stop.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin for
each of the driven wheels. If wheel spin is
detected, the TCS may apply brake pressure to the
spinning wheel(s) and/or reduce vehicle power to
provide enhanced acceleration and stability. A
feature of the TCS, Brake Limited Differential (BLD)
functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one
wheel on a driven axle is spinning faster than the
other, the system will apply the brake of the
spinning wheel. This will allow more vehicle torque
to be applied to the wheel that is not spinning.
BLD may remain enabled even if TCS and ESC are
in reduced modes.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
TSC will become active automatically once an
excessively swaying trailer is recognized.
NOTE:TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the
trailer tongue weight recommendations
Úpage 154.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced and you may feel the
brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial
Off” or “Full Off” modes.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM) —
I
F EQUIPPED
The BSM system uses two radar sensors, located
inside the rear fascia/bumper, to detect highway
licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light
will momentarily illuminate in both outside
rearview mirrors to let the driver know that the
system is operational. The BSM system sensors
operate when the vehicle is in any forward gear
and enters standby mode when the vehicle is
in PARK.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.

22_MP_OM_EN_USC_t.book Page 194

SAFETY199
If a Forward Collision Warning with Mitigation event
begins at a speed below 39 mph (62 km/h), the
system may provide the maximum braking
possible to mitigate the potential forward collision.
If the Forward Collision Warning with Mitigation
event stops the vehicle completely, the system will
hold the vehicle at standstill for two seconds and
then release the brakes.

FCW Message

When the system determines a collision with the
vehicle in front of you is no longer probable, the
warning message will be deactivated Úpage 328.
NOTE:
The minimum speed for FCW activation is
1 mph (2 km/h).
The FCW alerts may be triggered on objects
other than vehicles such as guardrails or sign
posts based on the course prediction. This is
expected and is a part of normal FCW activation
and functionality.
It is unsafe to test the FCW system. To prevent
such misuse of the system, after four Active
Braking events within a key cycle, the Active
Braking portion of FCW will be deactivated until
the next key cycle.
The FCW system is intended for on-road use
only. If the vehicle is taken off-road, the FCW
system should be deactivated to prevent unnec -
essary warnings to the surroundings.
FCW Settings
The Forward Collision menu setting is located in
the Uconnect Settings Ú page 165.
NOTE:The default status of FCW is “Full On,” this allows
the system to provide warning and autonomous
braking in the event of a potential frontal collision.
Changing the FCW status to “Only Warning”
prevents the system from providing autonomous
braking, or additional brake support if the driver is
not braking adequately in the event of a potential
frontal collision.
Changing the FCW status to “Off” deactivates the
system, so no warning or autonomous braking will
be available in case of a possible collision.
NOTE:The FCW system state is kept in memory from one
ignition cycle to the next. If the system is turned off,
it will remain off when the vehicle is restarted.
Changing FCW Sensitivity And Operating
Status
The FCW Sensitivity and Operation settings are
programmable through the Uconnect system
Úpage 165.
The default status of FCW is the “Medium” setting
and the FCW is in the “Full On” setting. This allows
the system to warn the driver of a possible collision
WARNING!
Forward Collision Warning (FCW) is not intended
to avoid a collision on its own, nor can FCW
detect every type of potential collision. The driver
has the responsibility to avoid a collision by
controlling the vehicle via braking and steering.
Failure to follow this warning could lead to
serious injury or death.

200SAFETY
with the vehicle in front using audible/visual
warnings and it applies autonomous braking.
Changing the FCW status to the “Far” setting
allows the system to warn the driver of a possible
collision with the vehicle in front using audible/
visual warnings when the latter is at a farther
distance than in the "Medium" setting. This
provides the most reaction time to avoid a possible
collision.
Changing the FCW status to the “Near” setting
allows the system to warn the driver of a possible
collision with the vehicle in front when the vehicle
in the front is much closer. This setting provides
less reaction time than the “Far” and “Medium”
settings, which allows for a more dynamic driving
experience.
NOTE:
The system will retain the last setting selected
by the driver after ignition shut down.
FCW may not react to irrelevant objects such as
overhead objects, ground reflections, objects
not in the path of the vehicle, stationary objects
that are far away, oncoming traffic, or leading
vehicles with the same or higher rate of speed.
If FCW is disabled, unavailable screens will be
displayed.
FCW Limited Warning
If the instrument cluster display reads “FCW
Limited Functionality” or “FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that limits
FCW functionality. Although the vehicle is still
driveable under normal conditions, the active
braking may not be fully available. Once the
condition that limited the system performance is
no longer present, the system will return to its full
performance state. If the problem persists, see an
authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster
display reads “FCW Unavailable Service Required”,
there is an internal system fault. Although the
vehicle is still driveable under normal conditions,
have the system checked by an authorized dealer.
Pedestrian Emergency Braking (PEB) —
If Equipped
PEB is a subsystem of the Forward Collision
Warning (FCW) system which provides the driver
with audible warnings and visual warnings, in the
instrument cluster display. It may apply limited
automatic braking when it detects a potential
frontal collision with a pedestrian/cyclist.
PEB Message

If a PEB event begins at a speed below 39 mph
(62 km/h), the system may provide maximum
braking to mitigate the potential collision with a
pedestrian. If the PEB event stops the vehicle
completely, the system will hold the vehicle at a
standstill for two seconds and then release the
brakes. When the system determines a collision
with the pedestrian in front of you is no longer
probable, the warning message will be
deactivated.
The minimum speed for PEB activation is 3 mph
(5 km/h).

EMERGENCY TOW HOOKS —
I
F EQUIPPED
If your vehicle is equipped with tow hooks, there
will be one in the rear and two mounted on the
front of the vehicle. The rear hook will be located
on the driver's side of the vehicle.
NOTE:For off-road recovery, it is recommended to use
both of the front tow hooks to minimize the risk of
damage to the vehicle.

Front Tow Hooks Location Rear Tow Hook Location

Vehicles With Keyless Enter ‘n Go™
Place the ignition in the ON/RUN position, and
subsequently in OFF, without opening the door.
During towing, remember that not having the aid of
the power brakes and the electromechanical
power steering will require greater force when
applying the brakes and steering of the vehicle.ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced
Accident Response System.
This feature is a communication network that
takes effect in the event of an impact Úpage 224.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is to
record data that will assist in understanding how a
vehicle’s systems performed under certain crash
or near crash-like situations, such as an air bag
deployment or hitting a road obstacle Úpage 227.
WARNING!
Do not use a chain for freeing a stuck vehicle.
Chains may break, causing serious injury or
death.
Stand clear of vehicles when pulling with tow
hooks. Tow straps may become disengaged,
causing serious injury.
CAUTION!
Tow hooks are for emergency use only, to rescue
a vehicle stranded off road. Do not use tow
hooks for tow truck hookup or highway towing.
You could damage your vehicle.

282SERVICING AND MAINTENANCE
(Continued)
Do not overfill the coolant expansion bottle.
Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant needs to be added, the contents of the
coolant expansion bottle must also be protected
against freezing.
If frequent engine coolant additions are
required, the cooling system should be pressure
tested for leaks.
Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corro-
sion protection of your engine which contains
aluminum components.
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces -
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically. For the proper maintenance intervals
Ú page 268.
Brake Master Cylinder
The fluid in the master cylinder should be checked
when performing under hood services or
immediately if the Brake Warning Light is
illuminated.
Be sure to clean the top of the master cylinder area
before removing the cap. If necessary, add fluid to
bring the fluid level up to the requirements
described on the brake fluid reservoir. With disc
brakes, fluid level can be expected to fall as the
brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low
fluid level may be caused by a leak and a checkup
may be needed. Use only the manufacturer recommended brake
fluid Ú
page 324.
WARNING!

Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting or
riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear,
and possible brake damage. You would not have
your full braking capacity in an emergency.

WARNING!
Use only the manufacturer recommended
brake fluid Úpage 324. Using the wrong type
of brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in a open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure.
This could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.

316SERVICING AND MAINTENANCE
When cleaning extremely dirty wheels including
excessive brake dust, care must be taken in the
selection of tire and wheel cleaning chemicals and
equipment to prevent damage to the wheels.
Mopar® Wheel Treatment, Mopar® Chrome
Cleaner or their equivalent is recommended, or
select a non-abrasive, non-acidic cleaner for
aluminum or chrome wheels.
NOTE:If you intend parking or storing your vehicle for an
extended period after cleaning the wheels with
wheel cleaner, drive your vehicle and apply the
brakes to remove the water droplets from the
brake components. This activity will remove the
red rust on the brake rotors and prevent vehicle
vibration when braking. Dark Vapor Chrome, Black Satin Chrome, or Low
Gloss Clear Coat Wheels
Cleaning Headlights
Your vehicle is equipped with plastic headlights
and fog lights that are lighter and less susceptible
to stone breakage than glass headlights.
Plastic is not as scratch resistant as glass and
therefore different lens cleaning procedures must
be followed.
To minimize the possibility of scratching the lenses
and reducing light output, avoid wiping with a dry
cloth. To remove road dirt, wash with a mild soap
solution followed by rinsing.
Do not use abrasive cleaning components,
solvents, steel wool or other aggressive material to
clean the lenses.
PRESERVING THE BODYWORK
Washing
Wash your vehicle regularly. Always wash your
vehicle in the shade using Mopar® Car Wash, or
a mild car wash soap, and rinse the panels
completely with water.
If insects, tar, or other similar deposits have
accumulated on your vehicle, use Mopar®
Super Kleen Bug and Tar Remover to remove.
Use a high quality cleaner wax, such as Mopar®
Cleaner Wax to remove road film, stains and to
protect your paint finish. Use precautions to not
scratch the paint.
Avoid using abrasive compounds and power
buffing that may diminish the gloss or thin out
the paint finish.
CAUTION!
Do not use scouring pads, steel wool, a bristle
brush, metal polishes or oven cleaner. These
products may damage the wheel's protective
finish. Such damage is not covered by the New
Vehicle Limited Warranty. Only car wash soap,
Mopar® Wheel Cleaner or equivalent is
recommended.
CAUTION!
If your vehicle is equipped with these specialty
wheels, DO NOT USE wheel cleaners, abrasives,
or polishing compounds. They will permanently
damage this finish and such damage is not
covered by the New Vehicle Limited Warranty.
HAND WASH ONLY USING MILD SOAP AND
WATER WITH A SOFT CLOTH. Used on a regular
basis; this is all that is required to maintain this
finish.
CAUTION!
Do not use abrasive or strong cleaning mate
-
rials such as steel wool or scouring powder
that will scratch metal and painted surfaces.
Use of power washers exceeding 1,200 psi
(8,274 kPa) can result in damage or removal
of paint and decals.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the
windshield and is visible from the outside of the
vehicle.
Vehicle Identification Number

NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with power assisted
brakes as standard equipment. In the event power
assist is lost for any reason (for example, repeated
brake applications with the engine off), the brakes will still function. However, the effort required to
brake the vehicle will be much greater than that
required with the power system operating.
If either of the two hydraulic systems lose normal
capability, the remaining system will still function
with some loss of overall braking effectiveness.
This will be evident by increased pedal travel
during application and greater pedal force
required to slow or stop. In addition, if the
malfunction is caused by an internal leak, as
the brake fluid in the master cylinder drops, the
Brake Warning Light will light.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six-sided (hex) deep wall
socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug
nuts/bolts and clean or remove any dirt or oil
before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
WARNING!
Driving a vehicle with the Brake Warning Light on
is dangerous. A significant decrease in braking
performance or vehicle stability during braking
may occur. It will take you longer to stop the
vehicle or will make your vehicle harder to
control. You could have a collision. Have the
vehicle checked immediately.
