For vehicles not equipped with an instrument
cluster display, perform the following steps:
1. Center the steering wheel (front wheels
pointing straight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more
than one-half turn to the left.
6. Push the “ESC Off” button located in the
lower switch bank below the climate con-
trol four times within 20 seconds. The
“ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center
and then an additional slightly more than
one-half turn to the right.
8. Turn the ignition to the OFF mode and
then back to ON. If the sequence was
completed properly, the “ESC Off Indica-
tor Light” will blink several times to con-
firm HSA is disabled.
9. Repeat these steps if you want to return
this feature to its previous setting.Towing With HSA
HSA will also provide assistance to mitigate
roll back while towing a trailer.
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 roll-
ing down an incline while resuming ac-
celeration, manually activate the trailer
brake or apply more vehicle brake pres-
sure 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 re-
sult in a collision or serious personal
injury.
Traction Control System (TCS)
This system 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 re-
duce engine power to provide enhanced ac-
celeration and stability. A feature of the TCS,
Brake Limited Differential (BLD), functions
similar to a limited slip differential and con-
trols 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. BLD may remain en-
abled even if TCS and ESC are in a reduced
mode.
Electronic Stability Control (ESC)
This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the
brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer
condition. Engine power may also be reduced
to help the vehicle maintain the desired path.
83
Page 86 of 368
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.
• 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.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will
start to flash as soon as the ESC system
becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes
when the TCS is active. If the “ESC
Activation/Malfunction Indicator Light” be-
gins 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.WARNING!
• Electronic Stability Control (ESC) can-
not prevent the natural laws of physics
from acting on the vehicle, nor can it
increase the traction afforded by prevail-
ing road conditions. ESC cannot prevent
accidents, including those resulting
from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
ESC also cannot prevent accidents re-
sulting from loss of vehicle control due
to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skill-
ful driver can prevent accidents. The
capabilities of an ESC equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopar-
dize the user’s safety or the safety of
others.
• Vehicle modifications, or failure to prop-
erly maintain your vehicle, may change
the handling characteristics of your ve-
hicle, and may negatively affect the per-
formance of the ESC system. Changes to
the steering system, suspension, brak-
WARNING!
ing system, tire type and size or wheel
size may adversely affect ESC perfor-
mance. Improperly inflated and un-
evenly worn tires may also degrade ESC
performance. Any vehicle modification
or poor vehicle maintenance that re-
duces the effectiveness of the ESC sys-
tem can increase the risk of loss of
vehicle control, vehicle rollover, per-
sonal injury and death.
ESC Operating Modes
NOTE:
Depending upon model and mode of opera-
tion, the ESC system may have multiple op-
erating modes.
ESC On
This is the normal operating mode for the
ESC. Whenever the vehicle is started, the
ESC system will be in this mode. This mode

WARNING!
• With the ESC switched off, the en-
hanced vehicle stability offered by ESC
is unavailable. In an emergency evasive
maneuver, the ESC system will not en-
gage to assist in maintaining stability.
ESC “Full Off” mode is only intended for
off-highway or off-road use.
• The Electronic Stability Control (ESC)
cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it
increase the traction afforded by prevail-
ing road conditions. ESC cannot prevent
all accidents, including those resulting
from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
ESC also cannot prevent collisions.
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 en-
gine running, a malfunction has been de-
tected in the ESC system. If this light re-
mains 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” (located in the instrument cluster)
starts to flash as soon as the tires lose trac-
tion 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 con-
ditions.NOTE:
• The “ESC Activation/Malfunction Indicator
Light” and the “ESC OFF Indicator Light”
come on momentarily each time the igni-
tion is turned ON.
• Each time the ignition is turned ON, the
ESC system will be on even if it was turned
off previously.
• The ESC system will make buzzing or click-
ing sounds when it is active. This is normal;
the sounds will stop when ESC becomes
inactive following the maneuver that
caused the ESC activation.
The “ESC OFF Indicator Light” indi-
cates the customer has elected to
have the Electronic Stability Control
(ESC) in a reduced mode.
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 vehi-
cle’s speed are sufficient to potentially cause
wheel lift, it then applies the appropriate

Rain Brake Support (RBS)
Rain Brake Support may improve braking
performance in wet conditions. It will periodi-
cally apply a small amount of brake pressure
to remove any water buildup on the front
brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When
Rain Brake Support is active, there is no
notification to the driver and no driver inter-
action is required.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the
ESC and Electric Power Steering (EPS) mod-
ules that provides torque at the steering
wheel for certain driving conditions in which
the ESC module is detecting vehicle instabil-
ity. The torque that the steering wheel re-
ceives is only meant to help the driver realize
optimal steering behavior in order to reach/
maintain vehicle stability. The only notifica-
tion the driver receives that the feature is
active is the torque applied to the steering
wheel.NOTE:
The DST feature is only meant to help the
driver realize the correct course of action
through small torques on the steering wheel,
which means the effectiveness of the DST
feature is highly dependent on the driver’s
sensitivity and overall reaction to the applied
torque. It is very important to realize that this
feature will not steer the vehicle, meaning
the driver is still responsible for steering the
vehicle.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off road driv-
ing while in 4WD Low Range. HDC maintains
vehicle speed while descending hills during
various driving situations. HDC controls ve-
hicle 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
activation conditions 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 auto-
matically if driven down a grade of sufficient
magnitude. The set speed for HDC is select-
able by the driver, and can be adjusted by
using the gear shift +/-. The following sum-
marizes 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)

Changing FCW System Status
The Forward Collision Warning settings are
located in the Uconnect display in the con-
trols settings.
NOTE:
• The default sensitivity of FCW is the “Me-
dium” setting and the system status is
“Warning & Braking”. This allows the sys-
tem to warn the driver of a possible colli-
sion with the vehicle in front using audible/
visual warnings and it applies autonomous
braking.
• Changing the FCW status to “Only Warn-
ing” prevents the system from providing
limited active braking, or additional brake
support if the driver is not braking ad-
equately in the event of a potential frontal
collision, but maintains the audible and
visual warnings.
• Changing the FCW status to “Off” 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. If FCW is set
to “Off”, “FCW OFF” will appear in the
instrument cluster display.Changing FCW Sensitivity
The FCW feature has three settings and can
be changed within the Uconnect System
Screen:
• Far
• Medium
• Near
Far
The far setting provides warnings for poten-
tial collisions more distant in front of the
vehicle, allowing the driver to have the most
reaction time to avoid a collision.
More cautious drivers that do not mind fre-
quent warnings may prefer this setting.
NOTE:
This setting gives you the most reaction time.
Medium
The default sensitivity of FCW is the “Me-
dium” setting and the system status is
“Warning & Braking”. This allows the system
to warn the driver of a possible collision with
the vehicle in front using audible/visual warn-
ings and it applies autonomous braking.Near
Changing the FCW sensitivity to the “Near”
setting, allows the system to warn you of a
potential frontal collision when you are much
closer.
This setting provides less reaction time than
the “Far” setting, which allows for a more
dynamic driving experience.
More dynamic or aggressive drivers that want
to avoid frequent warnings may prefer this
setting.
Refer to your Owner's Manual for further
details.
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 ve-
hicle via braking and steering. Failure to
follow this warning could lead to serious
injury or death.

the AHRs have deployed. The head restraint
must be reset into the original position to best
protect the occupant for all types of colli-
sions. An authorized FCA US LLC dealer must
reset the AHRs on the driver’s and front
passenger’s seat before driving. Personally
attempting to reset the AHRs may result in
damage to the AHRs that could impair their
function.
WARNING!
Deployed AHRs are not able to best protect
you in all types of collisions. Have de-
ployed AHRs reset by an authorized dealer
immediately.
Supplemental Restraint Systems (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask your autho-
rized dealer.The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal cir-
cuits and interconnecting wiring associated
with the electrical Air Bag System Compo-
nents. Your vehicle may be equipped with the
following Air Bag System Components:
Air Bag System Components
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system when-
ever the ignition switch is in the START or
ON/RUN position. If the ignition switch is in
the OFF position or in the ACC position, the
air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light
in the instrument panel for approximately
four to eight seconds for a self-check when
the ignition switch is first in the ON/RUN
position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects
a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime
will sound to alert you if the light comes on
again after initial startup.
109
Page 112 of 368
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag
Warning Light if a malfunction is detected
that could affect the air bag system. The
diagnostics also record the nature of the
malfunction. While the air bag system is
designed to be maintenance free, if any of
the following occurs, have an authorized
dealer service the air bag system immedi-
ately.
• The Air Bag Warning Light does not come
on during the four to eight seconds when
the ignition switch is first in the ON/RUN
position.
• The Air Bag Warning Light remains on after
the four to eight-second interval.
• The Air Bag Warning Light comes on inter-
mittently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the Oc-
cupant Restraint Controller (ORC) may also
be disabled. In this condition the air bags
may not be ready to inflate for your protec-
tion. Have an authorized dealer service the
air bag system immediately.WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t
have the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first
turned on, stays on after you start the
vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag
system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the Supplemen-
tal Restraint System (SRS), the Redundant
Air Bag Warning Light will illuminate on the
instrument panel. The Redundant Air Bag
Warning Light will stay on until the fault is
cleared. In addition, a single chime will
sound to alert you that the Redundant Air Bag
Warning Light has come on and a fault has
been detected. If the Redundant Air Bag
Warning Light comes on intermittently or
remains on while driving have an authorized
dealer service the vehicle immediately. Foradditional information regarding the Redun-
dant Air Bag Warning Light refer to “Getting
To Know Your Instrument Panel” section of
this manual.
Front Air Bags
This vehicle has front air bags and lap/
shoulder belts for both the driver and front
passenger. The front air bags are a supple-
ment to the seat belt restraint systems. The
driver front air bag is mounted in the center
of the steering wheel. The passenger front air
bag is mounted in the instrument panel,
above the glove compartment. The words
“SRS AIRBAG” or “AIRBAG” are embossed
on the air bag covers.

WARNING!
• Being too close to the steering wheel or
instrument panel during front air bag
deployment could cause serious injury,
including death. Air bags need room to
inflate. Sit back, comfortably extending

your arms to reach the steering wheel or
instrument panel.
• Never place a rear-facing child restraint
in front of an air bag. A deploying pas-
senger front air bag can cause death or
serious injury to a child 12 years or
younger, including a child in a rear-
facing child restraint.
• Only use a rear-facing child restraint in
the rear seat of a vehicle with a rear seat.
Driver And Passenger Front Air Bag Features
The Advanced Front Air Bag system has mul-
tistage driver and front passenger air bags.
This system provides output appropriate to
the severity and type of collision as deter-
mined by the Occupant Restraint Controller
(ORC), which may receive information from
the front impact sensors (if equipped) or
other system components.
The first stage inflator is triggered immedi-
ately during an impact that requires air bag
deployment. A low energy output is used in
less severe collisions. A higher energy output
is used for more severe collisions.This vehicle may be equipped with a driver
and/or front passenger seat belt buckle
switch that detects whether the driver or front
passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of
the Advanced Front Air Bags.
WARNING!
• No objects should be placed over or near
the air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a
collision severe enough to cause the air
bag to inflate.
• Do not put anything on or around the air
bag covers or attempt to open them
manually. You may damage the air bags
and you could be injured because the air
bags may no longer be functional. The
protective covers for the air bag cushions
are designed to open only when the air
bags are inflating.
• Relying on the air bags alone could lead
to more severe injuries in a collision. The
air bags work with your seat belt to
restrain you properly. In some collisions,

WARNING!
air bags won’t deploy at all. Always wear
your seat belts even though you have air
bags.
Front Air Bag Operation
Front Air Bags are designed to provide addi-
tional protection by supplementing the seat
belts. Front air bags are not expected to
reduce the risk of injury in rear, side, or
rollover collisions. The front air bags will not
deploy in all frontal collisions, including
some that may produce substantial vehicle
damage — for example, some pole collisions,
truck underrides, and angle offset collisions.
On the other hand, depending on the type
and location of impact, front air bags may
deploy in crashes with little vehicle front-end
damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
damage by themselves are not good indica-
tors of whether or not an air bag should have
deployed.Seat belts are necessary for your protection in
all collisions, and also are needed to help
keep you in position, away from an inflating
air bag.
When the ORC detects a collision requiring
the front air bags, it signals the inflator units.
A large quantity of non-toxic gas is generated
to inflate the front air bags.
The steering wheel hub trim cover and the
upper passenger side of the instrument panel
separate and fold out of the way as the air
bags inflate to their full size. The front air
bags fully inflate in less time than it takes to
blink your eyes. The front air bags then
quickly deflate while helping to restrain the
driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the
knees of the driver and front passenger, and
position the front occupants for improved
interaction with the front air bags.
WARNING!
• Do not drill, cut, or tamper with the knee
impact bolsters in any way.
• Do not mount any accessories to the
knee impact bolsters such as alarm
lights, stereos, citizen band radios, etc.
Supplemental Driver Knee Air Bag
This vehicle is equipped with a Supplemental
Driver Knee Air Bag mounted in the instru-
ment panel below the steering column. The
Supplemental Driver Knee Air Bag provides
enhanced protection during a frontal impact
by working together with the seat belts, pre-
tensioners, and front air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags
(SABs) (If Equipped)
Your vehicle may be equipped with Supple-
mental Seat-Mounted Side Air Bags (SABs).
If your vehicle is equipped with Supplemen-
tal Seat-Mounted Side Air Bags (SABs),
please refer to the information below.

WARNING!
inflate, even if they are in an infant or
child restraint.
• Seat belts (and child restraints where
appropriate) are necessary for your pro-
tection in all collisions. They also help
keep you in position, away from an in-
flating Side Air Bag. To get the best
protection from the Side Air Bags, occu-
pants must wear their seat belts properly
and sit upright with their backs against
the seats. Children must be properly
restrained in a child restraint or booster
seat that is appropriate for the size of the
child.
WARNING!
• Side Air Bags need room to inflate. Do
not lean against the door or window. Sit
upright in the center of the seat.
• Being too close to the Side Air Bags
during deployment could cause you to
be severely injured or killed.
• Relying on the Side Air Bags alone could
lead to more severe injuries in a colli-
WARNING!
sion. The Side Air Bags work with your
seat belt to restrain you properly. In
some collisions, Side Air Bags won’t
deploy at all. Always wear your seat belt
even though you have Side Air Bags.
NOTE:
Air bag covers may not be obvious in the
interior trim, but they will open during air bag
deployment.
Rollover Events (If Equipped With Rollover
Sensing)
Side Air Bags are designed to activate in
certain rollover events. The ORC determines
whether the deployment of the Side Air Bags
in a particular rollover event is appropriate,
based on the severity and type of collision.
Vehicle damage by itself is not a good indica-
tor of whether or not Side Air Bags should
have deployed.
The Side Air Bags will not deploy in all
rollover events. The rollover sensing system
determines if a rollover event may be in
progress and whether deployment is appro-priate. In the event the vehicle experiences a
rollover or near rollover event, and deploy-
ment of the Side Air Bags is appropriate, the
rollover sensing system will also deploy the
seat belt pretensioners on both sides of the
vehicle.
The SABICs may help reduce the risk of
partial or complete ejection of vehicle occu-
pants through side windows in certain roll-
over or side impact events.
