SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
If applicable, refer to the “Hybrid Supplement” for
additional information.
The ABS provides increased vehicle stability and
brake performance under most braking conditions.
The system automatically prevents wheel lock and
enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that
the ABS is working properly each time the vehicle
is started and driven. During this self-check, you
may hear a slight clicking sound as well as some
related motor noises.
The ABS is activated during braking when the
system detects one or more wheels are beginning
to lock. Road conditions such as ice, snow, gravel,
bumps, railroad tracks, loose debris, or panic stops
may increase the likelihood of ABS activation(s).You also may experience the following normal
characteristics when the ABS activates:
ABS motor noise or clicking sounds (you may
continue to hear for a short time after the stop)
Brake pedal pulsations
A slight drop of the brake pedal at the end of the
stop
The ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification
may result in degraded ABS performance.
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to interfer -
ence caused by improperly installed or high
output radio transmitting equipment. This
interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by qual -
ified professionals.
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer.
Just press firmly on your brake pedal when you
need to slow down or stop.
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase braking or steering efficiency beyond
that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The ABS cannot prevent collisions, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro -
planing.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner that could jeopardize the
user’s safety or the safety of others.

Anti-Lock Brake System (ABS)
Warning Light
The yellow ABS Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may
stay on for as long as four seconds.
If the ABS Warning Light remains on or comes on
while driving, it indicates that the anti-lock portion
of the brake system is not functioning and that
service is required. However, the conventional
brake system will continue to operate normally if
the ABS Warning Light is on.
If the ABS Warning Light is on, the brake system
should be serviced as soon as possible to restore
the benefits of anti-lock brakes. If the ABS Warning
Light does not come on when the ignition is placed
in the ON/RUN mode, have the light repaired as
soon as possible.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This system
includes Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Electronic Brake Force
Distribution (EBD), Electronic Roll Mitigation
(ERM), Electronic Stability Control (ESC), Hill Start Assist (HSA), and Traction Control System
(TCS).These systems work together to enhance
both vehicle stability and control in various driving
conditions.
Your vehicle may also be equipped with Dynamic
Steering Torque (DST), Ready Alert Braking (RAB),
Rain Brake Support (RBS) and Trailer Sway Control
(TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application and then applies optimum
pressure to the brakes. This can help reduce
braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes
very quickly results in the best BAS assistance. To
receive the benefit of the system, you must apply
continuous braking pressure during the stopping
sequence (do not “pump” the brakes). Do not
reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released,
the BAS is deactivated.
Brake System Warning Light
The red Brake System Warning Light will turn on
when the ignition is placed in the ON/RUN mode
and may stay on for as long as four seconds.
If the Brake System Warning Light remains on or
comes on while driving, it indicates that the brake
system is not functioning properly and that
immediate service is required. If the Brake System
Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
WARNING!
The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions. BAS cannot
prevent collisions, including those resulting from
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of a
BAS-equipped vehicle must never be exploited in
a reckless or dangerous manner, which could
jeopardize the user's safety or the safety of
others.

Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:
Úpage 188.
Towing With HSA
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 RBS
is active, there is no notification to the driver and
no driver interaction is required.
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
Control (EBC) system will prepare the brake system
for a panic stop.
Rear Seat Reminder Alert (RSRA)
RSRA will consider the presence of an object in the
rear seat when a rear entry/exit door is opened at
the beginning of each key cycle. To activate, the
rear door must be open for more than one second
and the vehicle must be placed in the ON/RUN
position within 10 minutes. When the potential
presence of an object is determined and/or
otherwise inferred, a message will appear in the
instrument cluster display reminding driver to
check the rear seat(s) immediately after key off
accompanied by an alert upon exiting the vehicle.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of
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.
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.

22_RUP_OM_EN_USC_t.book Page 228

SAFETY229
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 the Electronic
Stability Control (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.
Note that TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and follow
the trailer tongue weight recommendations
Ú page 174.
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” mode.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BS M) —
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 (P). The BSM detection zone covers approximately one
lane width on both sides of the vehicle 12 ft
(3.7 m). The zone length starts at the outside
rearview mirror and extends approximately 10 ft
(3 m) beyond the rear fascia/bumper of the
vehicle. The BSM system monitors the detection
zones on both sides of the vehicle when the vehicle
speed reaches approximately 6 mph (10 km/h) or
higher and will alert the driver of vehicles in these
areas.
NOTE:
The BSM system DOES NOT alert the driver
about rapidly approaching vehicles that are
outside the detection zones.
The BSM system detection zone DOES NOT
change if your vehicle is towing a trailer. There
-
fore, visually verify the adjacent lane is clear for
both your vehicle and trailer before making a
lane change. If the trailer or other object
(i.e., bicycle, sports equipment) extends beyond
the side of your vehicle, this may result in false
detections. The BSM Warning Light may even
remain illuminated the entire time the vehicle is
in a forward gear.
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_RUP_OM_EN_USC_t.book Page 229

SAFETY233
When the system is in RCP, the system shall
respond with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio is also muted. Turn/
hazard signal status is ignored; the RCP state
always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off there will be no
visual or audible alerts from either the BSM or RCP
systems.
NOTE:
The BSM system will store the current operating
mode when the vehicle is shut off. Each time the
vehicle is started the previously stored mode
will be recalled and used.
The BSM system can work in conjunction with
the KeySense function of the vehicle
(if equipped) Ú page 115.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
FCW with Mitigation provides the driver with
audible warnings, visual warnings (within the
instrument cluster display), and may apply a brake
jerk to warn the driver when it detects a potential
frontal collision. The warnings and limited braking
are intended to provide the driver with enough time
to react, avoid or mitigate the potential collision.
NOTE:FCW monitors the information from the forward
looking sensors as well as the Electronic Brake
Controller (EBC), to calculate the probability of a
forward collision. When the system determines
that a forward collision is probable, the driver will
be provided with audible and visual warnings and
may provide a brake jerk warning.
If the driver does not take action based upon these
progressive warnings, then the system will provide
a limited level of active braking to help slow the
vehicle and mitigate the potential forward collision.
If the driver reacts to the warnings by braking and
the system determines that the driver intends to
avoid the collision by braking but has not applied
sufficient brake force, the system will compensate
and provide additional brake force as required.
If a FCW with Mitigation event begins at a speed
below 37 mph (60 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. If a pedestrian is encountered in the path
at the same speed threshold, the system will
attempt to bring the vehicle to a stop.
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 370.
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.

SAFETY235
FCW Limited Warning
If the instrument cluster displays “ACC/FCW
Limited Functionality”, “FCW Limited
Functionality”, “ACC/FCW Limited Functionality
Clean Front Windshield”, or “FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that limits
FCW functionality. Although the vehicle is still
drivable 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
displays:
ACC/FCW Unavailable Service Required
FCW Unavailable Service Required
This indicates there is an internal system fault.
Although the vehicle is still drivable under normal
conditions, have the system checked by an
authorized dealer.
Pedestrian Emergency Braking (PEB) —
If Equipped
PEB is a subsystem of the FCW system which
provides the driver with audible and visual
warnings in the instrument cluster display, and
may apply automatic braking when it detects a
potential frontal collision with a pedestrian.

PEB Message

If a PEB event begins at a speed below 37 mph
(60 km/h), the system may provide 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).
Turning PEB On Or Off
NOTE:The default status of PEB is “On.” This allows the
system to warn you of a possible frontal collision
with the pedestrian.
The PEB button is located in the Uconnect display
in the Controls settings Ú
page 188.
To turn the PEB system off, push the Pedestrian
Emergency Braking OFF button.
To turn the PEB system back on, push the Warning
Active Braking button.
WARNING!
Pedestrian Emergency Braking (PEB) is not
intended to avoid a collision on its own, nor can
PEB detect every type of potential collision with
a pedestrian. 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.

(Continued)
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 310.
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 manufacturer recommended brake fluid
Úpage 366.
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 manufacturer recommended brake
fluid Ú page 366. 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 an 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.
Do not allow petroleum-based fluid to contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.

SERVICING AND MAINTENANCE353
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 or 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 WheelsSNOW TRACTION DEVICES
Use of traction devices require sufficient
tire-to-body clearance. Due to limited clearance,
the following snow traction devices are
recommended. Follow these recommendations to
guard against damage:
Snow traction device must be of proper size for
the tire, as recommended by the snow traction
device manufacturer.
No other tire sizes are recommended for use
with the snow traction device.
Please follow the table for the recommended
tire size, axle and snow traction device:
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
