SAFETY 205
wheel lift occurring during severe or evasive driving maneu-
vers; 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 (if
equipped). Refer to “Electronic Stability Control (ESC)” in
this section for a complete explanation of the available ESC
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 automati
-
cally 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. Refer to “Trailer Towing” in
“Starting And Operating” for further information.
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.
WARNING!
Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or roll overs, 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.
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.

206 SAFETY
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 activationconditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling vehicle 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 5 mph (8 km/h).
• Parking brake is released.
• Driver door is closed. Activating HDC
Once HDC is enabled it will activate automatically if driven
down a grade of sufficient magnitude. The set speed for
HDC is selectable by the driver, and can be adjusted by using
the gear shift +/-. The following summarizes the HDC set
speeds:
HDC Target Set Speeds

• P = No set speed. HDC may be enabled but will not activate.

• R = 0.6 mph (1 km/h)
• N = 1.2 mph (2 km/h)
• D = 0.6 mph (1 km/h)
• 1st = 0.6 mph (1 km/h)
• 2nd = 1.2 mph (2 km/h)
• 3rd = 1.8 mph (3 km/h)
• 4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
• 6th = 3.7 mph (6 km/h)
• 7th = 4.3 mph (7 km/h)
• 8th = 5.0 mph (8 km/h)
• 9th = 5.6 mph (9 km/h) – If Equipped

SAFETY 207
NOTE:
During HDC the +/- shifter input is used for HDC target
speed selection, but will not affect the gear chosen by the
transmission. When actively controlling HDC the transmis-
sion will shift appropriately for the driver-selected set speed
and corresponding driving conditions.
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 20 mph (32 km/h) but remains below 40 mph (64 km/h).
• Vehicle is on a downhill grade of insufficient magnitude, 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.
• The parking brake is applied.
• Driver door opens.
• The vehicle is driven greater than 20 mph (32 km/h) for
greater than 70 seconds.
• The vehicle is driven greater than 40 mph (64 km/h) (HDC exits immediately).
• HDC detects excessive brake temperature.

208 SAFETY
Feedback To The Driver
The instrument cluster has an HDC icon and the HDC switch
has an LED icon, which offers feedback to the driver about
the state HDC is in.
• The cluster icon and switch lamp will illuminate andremain on solid when HDC is enabled or activated. This is
the normal operating condition for HDC.
• The cluster icon and switch lamp will flash for several seconds then extinguish when the driver pushes the HDC
switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several seconds then extinguish when HDC disables due to excess
speed.
• The cluster icon and switch lamp will flash when HDC deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.AUXILIARY DRIVING SYSTEMS
Blind Spot Monitoring (BSM) — If Equipped
The Blind Spot Monitoring (BSM) system uses two
radar-based sensors, located inside the taillights, to detect
highway licensable vehicles (automobiles, trucks, motorcy -
cles, etc.) that enter the blind spot zones from the rear/front/
side of the vehicle.
Rear Detection Zones
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed.

216 SAFETY
Forward Collision Warning (FCW) With Mitigation — If
Equipped
The Forward Collision Warning (FCW) system provides the
driver with audible, visual warnings (within the instrument
cluster display), and may apply a haptic warning in the form
of a brake jerk, to warn the driver when it detects a potential
frontal collision. The warnings 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 Electronic Brake Controller (EBC), to calcu-
late 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 haptic warning in the form of a brake jerk.
If the driver does not take action based upon these progres-
sive 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 warn -
ings 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
32 mph (52 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.

218 SAFETY
• When FCW status is set to “Only Warning” prevents thesystem from providing limited active braking, or addi -
tional brake support if the driver is not braking adequately
in the event of a potential frontal collision.
• 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 system will retain the last setting selected by the driver after ignition shutdown.
FCW Braking Status And Sensitivity
The FCW sensitivity and Active Braking status are program -
mable through the Uconnect System. Refer to “Uconnect
Settings” in “Multimedia” in the Owner's Manual for further
information.
• Far
•When the sensitivity of FCW is set to the “Far” settingand the system status is “Warning and Braking”, this
allows the system to warn the driver of a possible more
distant collisions with the vehicle in front using
audible/visual warnings. • More cautious drivers that do not mind frequent warn
-
ings may prefer this setting.
• Medium •When the sensitivity of FCW is set to the “Medium”setting and the system status is “Warning and
Braking”, 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” settingand the system status is “Warning and Braking”, this
allows the system to warn the driver of a possible closer
collisions 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 experience.
•More dynamic or aggressive drivers that want to avoid frequent warnings may prefer this setting.

NOTE:
After an accident, remember to cycle the ignition to the STOP
(OFF/LOCK) position and remove the key from the ignition
switch to avoid draining the battery. Carefully check the
vehicle for fuel leaks in the engine compartment and on the
ground near the engine compartment and fuel tank before
resetting the system and starting the engine. If there are no
fuel leaks or damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the system by following
the procedure described below. If you have any doubt,
contact an authorized dealer. Enhanced Accident Response System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be changed
from ignition START or ON/RUN to ignition OFF. Carefully
check the vehicle for fuel leaks in the engine compartment
and on the ground near the engine compartment and fuel
tank before resetting the system and starting the engine.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag system could cause it to fail when you need it. You could be injured
if the air bag system is not there to protect you. Do not
modify the components or wiring, including adding
any kind of badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the instru -
ment panel. Do not modify the front bumper, vehicle
body structure, or add aftermarket side steps or
running boards.
• It is dangerous to try to repair any part of the air bag system yourself. Be sure to tell anyone who works on
your vehicle that it has an air bag system.

SAFETY 257
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 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 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 identi -
fying 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.
• Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may not
function properly if modifications are made. Take your
vehicle to an authorized dealer for any air bag system
service. If your seat, including your trim cover and
cushion, needs to be serviced in any way (including
removal or loosening/tightening of seat attachment
bolts), take the vehicle to an authorized dealer. Only
manufacturer approved seat accessories may be used. If
it is necessary to modify the air bag system for persons
with disabilities, contact an authorized dealer.

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!
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 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.

Periodic Safety Checks You Should Make 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 wheel bolts 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 make sure objects cannot fall or slide into the
driver’s side floor area when the vehicle is moving.
Objects can become trapped under accelerator, 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 posi -
tion 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.
