SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)

The ABS is designed to aid the driver in maintaining
vehicle control under adverse braking conditions. The
system operates with a separate computer to modulate
hydraulic pressure, to prevent wheel lock-up and to
help avoid skidding on slippery surfaces.

The system's pump motor runs during an ABS stop
to provide regulated hydraulic pressure. The pump
motor makes a low humming noise during
operation, which is normal.
The ABS includes an amber ABS Warning Light.
When the light is illuminated, the ABS is not
functioning. The system reverts to standard
non-anti-lock brakes. Placing the ignition in the
OFF mode and to the ON mode again may reset the
ABS if the fault detected was only momentary.When you are in a severe braking condition
involving the use of the ABS, you will experience
some pedal drop as the vehicle comes to a stop.
This is the result of the system reverting to the
base brake system.
Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking
noise. These occurrences are normal and indicate
that the system is functioning properly.
WARNING!

The ABS contains sophisticated electronic equip
-
ment that may be susceptible to interference
caused by improperly installed or high output
radio transmitting equipment. This interference
can cause possible loss of anti-lock braking capa -
bility. Installation of such equipment should be
performed by qualified 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.

ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system that
includes the Brake Assist System (BAS), Crosswind
Assist (CWA), Electronic Stability Control (ESC), Hill
Start Assist (HSA), Traction Control System (TCS),
and Trailer Sway Control (TSC). These systems
complement the Anti-Lock Brake System (ABS) by
optimizing the vehicle braking capability during
emergency braking maneuvers.
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.Crosswind Assist (CWA)

CWA helps keep your vehicle from drifting out of its lane
due to unexpected crosswinds by means of targeted
braking of individual wheels. The system will provide
automatic stability assistance to counteract the effect
of strong side wind. If a strong lateral wind is detected,
front and rear brakes on the affected side are applied,
creating a steering effect that mitigates the crosswind
influence. During system intervention, the driver should
perceive the natural stable handling feel of the vehicle.
Crosswind Assist will activate automatically when
the vehicle reaches speeds above approximately
43 mph (70 km/h). When the system is activated,
the ESC Warning Light in the instrument cluster will
blink to warn the driver.
Electronic Stability Control (ESC)
ESC enhances directional control and stability of
the vehicle under various driving conditions. ESC
corrects for over/under steering of the vehicle by
applying the brake of the appropriate wheel(s) to
counteract the above conditions. Engine power
may also be reduced to help the vehicle maintain
the desired path.
Oversteer – when the vehicle is turning more
than appropriate for the steering wheel position.
Understeer – when the vehicle is turning less
than appropriate for the steering wheel position.

ESC uses sensors in the vehicle to determine the
vehicle path intended by the driver and compares it to
the actual path of the vehicle. When the actual path
does not match the intended path, ESC applies the
brake of the appropriate wheel to assist in
counteracting the oversteer or understeer condition.

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.

140SAFETY
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 turned to 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 (kilometers) 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 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
that the Electronic Stability Control (ESC)
is in a reduced mode.
NOTE:
The ESC Activation/Malfunction Indicator Light
and the ESC OFF Indicator Light come on
momentarily each time the ignition switch is
placed in the ON position.
Each time the ignition is placed in the ON posi -
tion, 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.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver
when starting a vehicle from a stop on a hill. HSA
will maintain the level of brake pressure the driver
applied for a short period of time after the driver
takes their foot off of the brake pedal. If the driver
does not apply the throttle during this short period
of time, the system will release brake pressure and
the vehicle will roll down the hill. The system will
release brake pressure in proportion to the
amount of throttle applied as the vehicle starts
to move in the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA
to activate:
The vehicle must be stopped.
The vehicle must be on a 6% (approximate)
grade or greater hill.
Gear selection matches vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear;
vehicle backing uphill is in REVERSE gear).
HSA will work in REVERSE and all forward gears
when the activation criteria have been met.
The system will not activate if the vehicle is placed
in NEUTRAL or PARK.
WARNING!
There may be situations on minor hills with a
loaded vehicle, or while pulling a trailer, when
the system will not activate and slight rolling may
occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.

22_VF_OM_EN_USC_t.book Page 140

SAFETY141
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Traction Control System (TCS)
TCS monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and
engine power is reduced, 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 engine torque to be applied to the
wheel that is not spinning. This feature remains
active even if the ESC is in the “Partial Off” mode.
The ESC Activation/Malfunction Indicator Light (in
the instrument cluster) will start to flash as soon as
the tires lose traction and the wheels begin to spin.
This indicates that the TCS is active. If the indicator
light flashes 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, and do not switch off
the ESC or TCS.
Trailer Sway Control (TSC) — If Equipped
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
The system may reduce engine power and apply
the brake of the appropriate wheel(s) to counteract
the sway of the trailer.
NOTE:TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the
trailer tongue weight recommendations
Ú
page 110.
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.
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.
WARNING!
The TCS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase the traction afforded.
The TCS cannot prevent collisions, including
those resulting from excessive speed in turns,
or hydroplaning.
The capabilities of a TCS-equipped vehicle
must never be exploited in a reckless or
dangerous manner, which could jeopardize
the user's safety or the safety of others.
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.

148SAFETY
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
The FCW with Mitigation system 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 camera 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 as
well as a possible 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 26 mph (42 km/h), the system may provide
the maximum braking possible to mitigate the
potential forward collision. Vehicles With Automatic
Transmission: After the end of the intervention of
automatic braking, the transmission may remain in
last gear stored — therefore the vehicle could lurch
forward, once the brakes release a few seconds
later. 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.
NOTE:
The minimum speed for FCW activation is
3 mph (5 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 the Active Braking
portion of FCW will be deactivated for the first
20 seconds from braking actuation.
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 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.
FCW will be disabled with the unavailable
screens Ú page 256.

SAFETY149
Turning FCW On Or Off
The FCW button is located in the Uconnect display
in the control settings Ú page 120.
To turn the FCW system on, press the forward
collision button once.
To turn the FCW system off, press the forward
collision button once.
NOTE:
Changing the FCW status to “Off” deactivates
the system, so no warning or active braking will
be available in case of a possible collision.
Changing the FCW status to “Only Warning”
prevents the system from providing limited
active braking, or additional brake support if the
driver is not braking adequately in the event of
a potential frontal collision, but maintains the
audible and visual warnings.
When FCW status is set to “Warning and
Braking”, this allows the system to warn the
driver of a possible collision with the vehicle in
front using audible/visual warnings and it
applies autonomous braking.
The FCW system state is kept in memory from
one ignition position to the next. If the system is
turned off, it will maintain its status in the next
key cycle.
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status are
programmable through the Uconnect system
Úpage 120.
Far
When the sensitivity of FCW is set to the
“Far” setting and the system status is “Only
Warning”, this allows the system to warn the
driver of a possible more distant collision
with the vehicle in front using audible/
visual warnings.
More cautious drivers that do not mind
frequent warnings may prefer this setting.
NOTE:The “Far” setting may result in a greater
number of FCW possible collision warnings
experienced.
Medium
When the sensitivity of FCW is set to the
“Medium” setting and the system status is
“Only Warning”, this allows the system to
warn the driver of a possible collision with
the vehicle in front using audible/visual
warnings.
Near
When the sensitivity of FCW is set to the
“Near” setting and the system status is
“Only Warning”, this allows the system to
warn the driver of a possible closer collision
with the vehicle in front using audible/
visual warnings.
This setting provides less reaction time than
the “Far” and “Medium” settings, which
allows for a more dynamic driving experi -
ence.
More dynamic or aggressive drivers that
want to avoid frequent warnings may prefer
this setting.
NOTE:The “Near” setting may result in a lesser number of
FCW possible collision warnings experienced.
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.

for a short period of time, typically 30 seconds or
less. The EDR in this vehicle is designed to record
such data as:

How various systems in your vehicle were oper -
ating;
Whether or not the driver and passenger safety
belts were buckled/fastened;
How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in which
crashes and injuries occur.
NOTE:EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are
recorded by the EDR under normal driving condi -
tions and no personal data (e.g., name, gender,
age, and crash location) are recorded. However,
other parties, such as law enforcement, could
combine the EDR data with the type of personally
identifying data routinely acquired during a crash
investigation.
To read data recorded by an EDR, special equipment
is required, and access to the vehicle or the EDR is
needed. In addition to the vehicle manufacturer,
other parties, such as law enforcement, that have
the special equipment, can read the information if
they have access to the vehicle or the EDR.

CHILD RESTRAINTS
Everyone in your vehicle needs to be buckled up at
all times, including babies and children. Every
state in the United States, and every Canadian
province, requires that small children ride in
proper restraint systems. This is the law, and you
can be prosecuted for ignoring it.
Children 12 years or younger should ride properly
buckled up in a rear seat, if available. According to
crash statistics, children are safer when properly
restrained in the rear seats rather than in the front.
There are different sizes and types of restraints for
children from newborn size to the child almost
large enough for an adult safety belt. Always check
the child seat Owner’s Manual to make sure you
have the correct seat for your child. Carefully read
and follow all the instructions and warnings in the
child restraint Owner’s Manual and on all the
labels attached to the child restraint.
Before buying any restraint system, make sure that
it has a label certifying that it meets all applicable
Safety Standards. You should also make sure that
you can install it in the vehicle where you will use it.
NOTE:
For additional information, refer to http://
www.nhtsa.gov/parents-and-caregivers or

Canadian residents should refer to Transport
Canada’s website for additional information:
http://www.tc.gc.ca/en/services/road/
child-car-seat-safety.htmlWARNING!
In a collision, an unrestrained child can become
a projectile inside the vehicle. The force required
to hold even an infant on your lap could become
so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured or killed. Any child riding
in your vehicle should be in a proper restraint for
the child’s size.

TRANSPORTING PETS
Air Bags deploying in the front seat could harm
your pet. An unrestrained pet will be thrown about
and possibly injured, or injure a passenger during
panic braking or in a collision.

Pets should be restrained in the rear seat (if equipped)
in pet harnesses or pet carriers that are secured by
seat belts.

SAFETY CHECKS YOU SHOULD MAKE
I
NSIDE THE VEHICLE
Seat Belts
Inspect the seat belt system periodically, checking
for cuts, frays, and loose parts. Damaged parts
must be replaced immediately. Do not
disassemble or modify the system.
If your vehicle is involved in a collision, or if you
have questions regarding the seat belt or retractor
conditions, take your vehicle to an authorized FCA
dealer or authorized FCA Certified Collision Care
Program facility for inspection.
Air Bag Warning Light
The Air Bag Warning Light will turn on for
four to eight seconds as a bulb check
when the ignition switch is first placed in
the MAR (ACC/ON/RUN) position. If the
light is either not on during starting, stays on, or
turns on while driving, have the system inspected
at an authorized dealer as soon as possible. After
the bulb check, this light will illuminate with a
single chime when a fault with the Air Bag System
has been detected. It will stay on until the fault is
removed. If the light comes on intermittently or
remains on while driving, have an authorized
dealer service the vehicle immediately
Ú page 154.
Defroster
Check operation by selecting the defrost mode and
place the blower control on high speed. You should
be able to feel the air directed against the
windshield. See an authorized dealer for service if
your defroster is inoperable.
Floor Mat Safety Information

Always use floor mats designed to fit your vehicle.
Only use a floor mat that does not interfere with the
operation of the accelerator, brake or clutch pedals.
Only use a floor mat that is securely attached using the
floor mat fasteners so it cannot slip out of position and
interfere with the accelerator, brake or clutch pedals or
impair safe operation of your vehicle in other ways.

WARNING!
It is not possible to know or to predict all of the
possible outcomes if your vehicle’s systems are
breached. It may be possible that vehicle
systems, including safety related systems, could
be impaired or a loss of vehicle control could
occur that may result in an accident involving
serious injury or death.
WARNING!
An improperly attached, damaged, folded,
or stacked floor mat, or damaged floor mat
fasteners may cause your floor mat to interfere
with the accelerator, brake, or clutch pedals and
cause a loss of vehicle control. To prevent
SERIOUS INJURY or DEATH:
 ALWAYS securely attach your floor
mat using the floor mat fasteners.
DO NOT install your floor mat upside
down or turn your floor mat over.
Lightly pull to confirm mat is secured using the
floor mat fasteners on a regular basis.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nut/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
 ALWAYS REMOVE THE EXISTING
FLOOR MAT FROM THE VEHICLE
before installing any other floor mat.
NEVER install or stack an additional
floor mat on top of an existing floor mat.

ONLY install floor mats designed to fit your vehicle.
NEVER install a floor mat that cannot be properly
attached and secured to your vehicle. If a floor mat
needs to be replaced, only use a FCA approved
floor mat for the specific make, model, and year of
your vehicle.
ONLY use the driver’s side floor mat on the driver’s
side floor area. To check for interference, with the
vehicle properly parked with the engine off, fully
depress the accelerator, the brake, and the clutch
pedal (if present) to check for interference. If your
floor mat interferes with the operation of any
pedal, or is not secure to the floor, remove the
floor mat from the vehicle and place the floor mat
in your trunk.

ONLY use the passenger’s side floor mat on
the passenger’s side floor area.
WARNING!

ALWAYS make sure objects cannot fall or slide into
the driver’s side floor area when the vehicle is
moving. Objects can become trapped under accel -
erator, brake, or clutch pedals and could cause a
loss of vehicle control.

NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully depress
each pedal to check for interference with the
accelerator, brake, or clutch pedals then
re-install the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been properly
installed and is secured to your vehicle using
the floor mat fasteners by lightly pulling mat.
