FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION
The Forward Collision Warning (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 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 warn-
ings 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 Forward Collision Warning with Mitigation
event begins at a speed below 26 mph
(42 km/h), the system may provide the
maximum or partial braking 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 a 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
1 mph (2 km/h).
The FCW alerts may be triggered on objects
other than vehicles such as guard rails 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, after four
Active Braking events within an ignition cycle,
the Active Braking portion of FCW will be
deactivated until the next ignition cycle.
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
unnecessary warnings to the surroundings. If
the vehicle enters 4L range, the FCW system
will be automatically deactivated.

(Continued)
This is defined as the tire pressure after the
vehicle has not been driven for at least three
hours, or driven less than 1 mile (1.6 km) after
a three-hour period. Refer to “Tires” in
“Servicing And Maintenance” for information on
how to properly inflate the vehicle’s tires. The
tire pressure will also increase as the vehicle is
driven — this is normal and there should be no
adjustment for this increased pressure.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the low
pressure warning threshold for any reason,
including low temperature effects, or natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists,
and will not turn off until the tire pressure is at
or above recommended cold tire pressure.
Once the low tire pressure warning has been
illuminated, the tire pressure must be increased
to the recommended cold tire pressure in order
for the TPMS Warning Light to be turned off. NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off.
The system will automatically update and the
TPMS Warning Light will extinguish once the
updated tire pressures have been received. The
vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) to receive
this information.
For example, your vehicle has a recommended
cold (parked for more than three hours) tire
pressure of 33 psi (227 kPa). If the ambient
temperature is 68°F (20°C) and the measured
tire pressure is 28 psi (193 kPa), a temperature
drop to 20°F (-7°C) will decrease the tire
pressure to approximately 24 psi (165 kPa).
This tire pressure is sufficiently low enough to
turn on the TPMS Warning Light. Driving the
vehicle may cause the tire pressure to rise to
approximately 28 psi (193 kPa), but the TPMS
Warning Light will still be on. In this situation,
the TPMS Warning Light will turn off only after
the tires have been inflated to the vehicle’s
recommended cold tire pressure value.CAUTION!
The TPMS has been optimized for the orig
-
inal equipment tires and wheels. TPMS
pressures and warnings have been estab -
lished for the tire size equipped on your
vehicle. Undesirable system operation or
sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. The TPM
sensor is not designed for use on after -
market wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
OEM wheels to assure proper TPM feature
operation.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. After
using an aftermarket tire sealant it is
recommended that you take your vehicle to
an authorized dealership to have your
sensor function checked.

140SAFETY
NOTE:
The TPMS is not intended to replace normal
tire care and maintenance, or to provide
warning of a tire failure or condition.
The TPMS should not be used as a tire pres -
sure gauge while adjusting your tire pressure.
Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsi -
bility to maintain correct tire pressure using
an accurate tire gauge, even if under-infla -
tion has not reached the level to trigger illu -
mination of the TPMS Warning Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor the
actual tire pressure in the tire.
The Tire Pressure Monitoring System (TPMS)
uses wireless technology with wheel
rim-mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire
pressure readings to the Receiver Module.

Tire Pressure Monitoring Display

NOTE:
It is particularly important for you to regularly
check the tire pressure in all of your tires and to
maintain the proper pressure. The Tire Pressure Monitoring System (TPMS)
consists of the following components:
Receiver Module
Four Tire Pressure Monitoring sensors
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster, and a graphic displaying tire pres
-
sures
TPMS Warning Light
Tire Pressure Monitoring Low Pressure
Warnings
The TPMS Warning Light will
illuminate in the instrument cluster,
and an audible chime will be
activated, when one or more of the
four active road tire pressures are low. In
addition, the instrument cluster will display an
"Inflate to XX" message and a graphic display of
the pressure value(s) with the low tire(s) in a
different color. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instrument
Panel” for further information.
After inspecting or adjusting the tire pres -
sure, always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could
damage the Tire Pressure Monitoring
sensor.
CAUTION! (Continued)

SAFETY141
NOTE:
Your system can be set to display pressure units
in PSI, BAR or kPa.

Low Tire Pressure Monitoring Display

Should a low tire condition occur on any of the
four active road tire(s), you should stop as soon
as possible, and inflate the low tire(s) that is in
a different color on the graphic display to the
vehicle’s recommended cold tire pressure
displayed in the “Inflate to XX” message.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off. The system will automatically update, the
graphic display of the pressure value(s) will
return to its original color and the TPMS
Warning Light will extinguish once the updated
tire pressure(s) have been received. The vehicle
may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this
information.
Service TPMS Warning
The Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds, and
remain on solid when a system fault is detected.
The system fault will also sound a chime. The
instrument cluster display will display a
“SERVICE TPM SYSTEM” message for a
minimum of five seconds. This message is then
followed by a graphic display, with “--“ in place
of the pressure value(s), indicating which Tire
Pressure Monitoring sensor(s) is not being
received.
If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the Tire
Pressure Monitoring System Warning Light will
no longer flash, the "SERVICE TPM SYSTEM"
message will not be present, and a pressure
value will be displayed instead of dashes. A
system fault can occur by any of the following:
Jamming due to electronic devices or driving
next to facilities emitting the same Radio
Frequencies as the TPM sensors.
Lots of snow or ice around the wheels or
wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPM
sensors.
NOTE:
There is no Tire Pressure Monitoring sensor in
the spare tire. The TPMS will not be able to
monitor the tire pressure. If you install the spare
tire in place of a road tire that has a pressure
below the low-pressure warning limit, upon the
next ignition switch cycle, the Tire Pressure
Monitoring System Warning Light will remain
on, a chime will sound, and the instrument
cluster display will still display a pressure value
in the different color graphic display and an
“Inflate to XX” message will be displayed.

142SAFETY
After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the Tire Pressure
Monitoring System Warning Light will flash on
and off for 75 seconds and then remain on
solid. In addition, the instrument cluster display
will display a “SERVICE TPM SYSTEM" message
for five seconds and then display dashes (--) in
place of the pressure value. For each subse -
quent ignition switch cycle, a chime will sound,
the Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds and
then remain on solid, and the instrument
cluster display will display a "SERVICE TPM
SYSTEM" message for five seconds and then
display dashes (--) in place of the pressure
value. Once you repair or replace the original
road tire, and reinstall it on the vehicle in place
of the spare tire, the TPMS will update automat -
ically.
In addition, the Tire Pressure Monitoring System
Warning Light will turn off and the graphic in the
instrument cluster display will display a new
pressure value instead of dashes (--), as long as
no tire pressure is below the low-pressure
warning limit in any of the four active road tires.
The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order
for the TPMS to receive this information.TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS)
can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and
tire assemblies that do not have TPMS sensors,
such as when installing winter wheel and tire
assemblies on your vehicle.
To deactivate the TPMS, first, replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
(TPM) sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS Warning Light will
flash on and off for 75 seconds and then remain
on. The instrument cluster will display the
“SERVICE TPM SYSTEM” message and then
display dashes (--) in place of the pressure
values.
Beginning with the next ignition cycle, the TPMS
will no longer chime or display the “SERVICE
TPM SYSTEM” message in the instrument
cluster but dashes (--) will remain in place of the
pressure values. To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPM sensors. Then, drive the
vehicle for up to 20 minutes above 15 mph
(24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for
75 seconds and then turn off. The instrument
cluster will display the “SERVICE TPM SYSTEM”
message and then display pressure values in
place of the dashes. On the next ignition cycle
the "SERVICE TPM SYSTEM" message will no
longer be displayed as long as no system fault
exists.

Resetting Active Head Restraints (AHR)

Active Head Restraint (AHR) Deployed

If the Active Head Restraints are triggered
during a collision, the front half of the head
restraint will be extended forward and
separated from the rear half of the head
restraint (See Image). Do not drive your vehicle
after the AHRs have deployed. The head
restraint must be reset into the original position
to best protect the occupant for all types of
collisions. 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.
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 an authorized
dealer.
The air bag system must be ready to protect you
in a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and
interconnecting wiring associated with the
electrical Air Bag System Components. 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
Seat Track Position Sensors
Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever 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.
WARNING!
Deployed AHRs are not able to best protect
you in all types of collisions. Have deployed
AHRs reset by an authorized dealer
immediately.

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.

Front Air Bag/Knee Bolster Locations
Driver And Passenger Front Air Bag
Features
The Advanced Front Air Bag system has
multistage driver and front passenger air bags.
This system provides output appropriate to the
severity and type of collision as determined 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 immediately
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.
This vehicle may be equipped with driver and/or
front passenger seat track position sensors that
may adjust the inflation rate of the Advanced
Front Air Bags based upon seat position.

2 — Passenger Knee Impact Bolster
3 — Driver Knee Impact Bolster/Supplemental
Driver Knee Air Bag
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 passenger
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.
Never install a rear-facing child restraint in
the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat. If
the vehicle does not have a rear seat, do
not transport a rear-facing child restraint in
that vehicle.

Front Air Bag Operation
Front Air Bags are designed to provide
additional 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 indicators
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!
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 colli
-
sion 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 manu -
ally. 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, air bags won’t
deploy at all. Always wear your seat belts
even though you have 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.
