Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the speed
of the vehicle. When ERM determines that the rate of
change of the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM will only
intervene during very severe or evasive driving maneu-
vers. ERM can only reduce the chance of wheel lift occur-
ring during severe or evasive driving maneuvers. It cannot
prevent wheel lift due to other factors, such as road
conditions, leaving the roadway, or striking objects or other
vehicles.
NOTE:ERM is disabled anytime the ESC is in “Full Off”
mode. Refer to Electronic Stability Control (ESC) in this
section for a complete explanation of the available ESC
modes.
WARNING!
Many factors, such as vehicle loading, road conditions,
and driving conditions, influence the chance that
(Continued)
WARNING! (Continued)
wheel lift or rollover may occur. Electronic Roll Miti-
gation (ERM) cannot prevent all wheel lift or rollovers,
especially those that involve leaving the roadway or
striking objects or other vehicles. The capabilities of an
ERM-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopardize
the user’s safety or the safety of others.
Traction Control System (TCS)
This system 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 system, Brake Limited Differential
(BLD), functions similar 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 TCS
and ESC are in the “Partial Off” mode or the “Full Off”
mode. Refer to “Electronic Stability Control (ESC)” in this
section for further information.

Dynamic Steering Torque (DST)
The DST function uses the integration of the ESC system
with the electric power steering to increase the safety level
of the whole car. In critical situations (understeering,
oversteering, braking with different grip conditions),
through the DST function the ESC system controls the
steering to implement an additional torque contribution on
the steering wheel, to suggest the most correct maneuver to
the driver. The coordinated action of brakes and steering
increases the safety and car control feeling.
NOTE:The DST is a driving aid system and does not
replace the driver ’s actions while driving the car.
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).
Hill Descent Control (Trailhawk)
178 SAFETY
2. Enabled (feature is enabled and ready but activationconditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling ve- hicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, but the
following conditions must also be met to enable HDC:
• Driveline is in 4WD Low Range.
• Vehicle speed is below 7.5 mph (12 km/h).
• Electric Park Brake (EPB) is released.
• Driver ’s door is closed.
Activating HDC
Once HDC is enabled, it will activate automatically if
driven down a grade of sufficient magnitude (greater than
approximately 8%). The set speed for HDC is selectable by
the driver and can be adjusted using brake and throttle
input. Driver Override:
The driver may override HDC activation with throttle or
brake application at anytime.
Deactivating HDC
HDC will be deactivated but remain available if any of the
following conditions occur:
•
Driver overrides HDC set speed with throttle or brake
application.
• Vehicle speed exceeds 7.5 mph (12 km/h) but remains
below 25 mph (40 km/h).
• Vehicle is on a downhill grade of insufficient magnitude
(less than approximately 8%), is on level ground, or is on
an uphill grade.
• Vehicle is shifted to PARK.
Disabling HDC
HDC will be deactivated and disabled if any of the
following conditions occur:
• The driver pushes the HDC switch.
• The driveline is shifted out of 4WD Low Range.
• Driver ’s door opens.

1. The device may not cause harmful interference. 2. The device must accept any interference received, in-
cluding interference that may cause undesired operation
of the device.
Changes or modifications to any of these systems by other
than an authorized service facility could void authorization
to use this equipment.
Forward Collision Warning (FCW) With Mitigation
Operation — If Equipped
The Forward Collision Warning (FCW) System with Miti-
gation 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 brak-
ing are intended to provide the driver with enough time to
react, avoid or mitigate the potential collision.
188 SAFETY
NOTE:
•FCW monitors the information from the forward look-
ing 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.
Vehicles With A Manual Transmission: After the end of
the intervention of automatic braking, the engine could
stall, unless the driver can depress the clutch pedal.
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.
If a Forward Collision Warning with Mitigation event
begins at a speed below 20 mph (32 km/h), the system may
provide the maximum braking possible to mitigate the
potential forward collision. If the Forward Collision Warn-
ing 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
5
SAFETY 189
•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.
Changing the status of the system is only possible with the
vehicle at a complete stop.
NOTE: The FCW system state is not kept in memory from
one ignition position to the next. If the system is turned off,
it will turn on when the vehicle is restarted.
Changing FCW Sensitivity
By changing the settings on the menu of the Uconnect
system, you can change the sensitivity of the system by
choosing one of the following three options: Near,Me-
dium orFar. Refer to “Uconnect Settings” in “Multime-
dia” for further information.
The default option is Medium. This setting provides that
the system notify the driver of a possible accident with the
vehicle ahead of it when the latter is at a standard distance,
intermediate between the other two possible settings.
By setting the sensitivity of the system to Far, the system
will warn the driver of a possible accident with the vehicle
in front when the latter is at a greater distance, giving you the chance to act on the brakes in a more limited and
gradual. This setting gives the driver the maximum pos-
sible time of reaction to prevent a possible accident.
By changing the option to
Near, the system will warn the
driver of a possible accident with the vehicle ahead of it
when the latter is a reduced distance. This setting offers a
reaction time to the driver lower than the settings Me-
dium andFar, in the case of a potential accident, while a
more dynamic driving of the vehicle.
The setting of the sensitivity of the system is maintained in
memory when the engine is switched off.FCW Limited Warning
If the instrument cluster display reads “FCW Limited
Functionality” or “FCW Limited Functionality Wipe 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 your authorized dealer.

Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in certain
crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems performed. The
EDR is designed to record data related to vehicle dynamics
and safety systems 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 operating;
• Whether or not the driver and passenger safety belts
were buckled/fastened;
• How far (if at all) the driver was depressing the accel-
erator 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 conditions 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 investi-
gation.
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.

Air Bag Warning Light
The Air Bag warning lightwill turn on for four to
eight seconds as a bulb check when the ignition switch
is first turned to ON/RUN. 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. This light will illuminate with a single
chime when a fault with the Air Bag Warning Light has
been detected, it will stay on until the fault is cleared. If
the light comes on intermittently or remains on while
driving, have an authorized dealer service the vehicle
immediately. Refer to “Occupant Restraints” in “Safety”
for further information.
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 your
authorized dealer for service if your defroster is inoper-
able.
Floor Mat Safety Information
Always use floor mats designed to fit the footwell of your
vehicle. Use only floor mats that leave the pedal area
unobstructed and that are firmly secured so that they cannot slip out of position and interfere with the pedals or
impair safe operation of your vehicle in other ways.
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.
• ALWAYS REMOVE THE EXISTING FLOOR MAT
FROM THE VEHICLE
before installing any
other floor mat. NEVER install or stack an addi-
tional 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.
