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 switch is
turned to the MAR (ON/RUN) position for
four seconds. 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 (km) 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 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
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
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.
Electronic Roll Mitigation (ERM)
ERM 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 can only reduce the chance of wheel lift
occurring 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.Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and size
or wheel size may adversely affect ESC perfor -
mance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any
vehicle modification or poor vehicle mainte -
nance that reduces the effectiveness of the
ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
WARNING!
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 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.

Hill Start Assist (HSA)
HSA 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 5% (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.
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
system, 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 TCS and ESC are in the “Partial Off”
mode Ú page 132.
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
Úpage 68.
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!
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.
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.

SAFETY135
AUXILIARY DRIVING SYSTEMS
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure.
The tire pressure will vary with temperature by
about 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. 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. The cold tire
inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
The tire pressure will also increase as the vehicle
is driven — this is normal and there should be no
adjustment for this increased pressure.
See Ú page 217 on how to properly inflate the
vehicle’s tires.
The TPMS will warn the driver of a low tire pressure
if the tire pressure falls below the low-pressure
warning limit for any reason, including low
temperature effects and 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
the recommended cold placard pressure. Once the
low tire pressure warning (TPMS Warning Light)
illuminates, you must increase the tire pressure to
the recommended cold placard pressure in order
for the TPMS Warning Light to turn off. The system
will automatically update and the TPMS Warning
Light will turn off once the system receives the
updated tire pressures. 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.
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.
For example, your vehicle may have a
recommended cold (parked for more than three
hours) placard pressure of 30 psi (207 kPa). If the
ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a
temperature drop to 20°F (-7°C) will decrease the
tire pressure to approximately 23 psi (158 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 27 psi (186 kPa), but the TPMS
Warning Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the tires
are inflated to the vehicle’s recommended cold
placard pressure value.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established 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.
Aftermarket wheels can cause sensor
damage.
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.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.
6

22_VM_OM_EN_USC_t.book Page 135

136SAFETY
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 pressure
gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi -
ciency 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 responsibility
to maintain correct tire pressure using an accu -
rate tire pressure gauge, even if underinflation
has not reached the level to trigger illumination
of the TPMS Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire Ú page 245.
Base System
This is the TPMS Warning Light located
in the instrument cluster.
The 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.
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module
Four TPMS sensors
Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System Warning Light
will illuminate in the instrument cluster, an audible
chime will be activated, and the “Check tire
pressure” text message will display when one or
more of the four active road tire pressures are low.
Should this occur, you should stop as soon as
possible, check the inflation pressure of each tire
on your vehicle, and inflate each tire to the
vehicle’s recommended cold placard pressure
value. 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.
Check TPMS Warnings
The TPMS Warning Light will flash on and off for 75
seconds and remain on solid when a system fault
is detected, an audible chime will be activated and
a proper text message will be displayed. If the
ignition key is cycled, this sequence will repeat
providing the system fault still exists. The TPMS
Warning Light will turn off when the fault condition
no longer exists. A system fault can occur with any
of the following scenarios:

1. Jamming due to electronic devices or driving next to facilities emitting the same radio
frequencies as the TPMS sensors.

2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
NOTE:Your vehicle can be equipped with either a Tire
Service Kit, a compact spare tire or a regular size
spare tire (with or without original TPMS sensor).

22_VM_OM_EN_USC_t.book Page 136

SAFETY137

1. Tire Service Kit (original tire sealant – if equipped): After fixing the punctured tire with
original tire sealant, the original situation will
be restored, so system will turn off the
warning light during the normal drive.

2. Compact Spare Tire (if equipped): The compact spare wheel is not equipped with a
TPMS sensor. So when mounted, during the
normal drive the system will turn on the
warning light (flashes for approximately 75
seconds then remains solid). This condition
persists until a wheel equipped with original
TPMS sensor has been mounted on the
vehicle.
3. Regular size spare tire (not equipped with TPMS sensor): When mounted, during the
normal drive the system will turn on the telltale
(flashes for approximately 75 seconds then
remains solid). This condition persists until a
wheel equipped with original TPMS sensor has
been mounted on the vehicle. Then the system
will be restored and the warning light will turn
off during the normal drive.
4. Regular size spare tire (equipped with TPMS sensor): When mounted, the warning light will
turn off during the normal drive.
5. In all the above cases, please check the replacement tire inflation pressure before
driving your vehicle. 6. In case of tire replacement, if the vehicle is
driven for short periods of time, then the
system can take a while to be restored.
NOTE:For a correct Tire Pressure Monitoring System
behavior, please wait for about 20 minutes in
key-off during each tire substitution.
OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your
vehicle are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air Bags
Child Restraints
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.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your passengers
as safe as possible. Here are some simple steps you can take to
minimize the risk of harm from a deploying air bag:

1. Children 12 years old and under should
always ride buckled up in the rear seat of a
vehicle with a rear seat.

2. A child who is not big enough to wear the vehicle seat belt properly must be secured in
the appropriate child restraint or
belt-positioning booster seat in a rear seating
position Ú page 166.
3. If a child from 2 to 12 years old (not in a rear-facing child restraint) must ride in the
front passenger seat, move the seat as far
back as possible and use the proper child
restraint Ú page 166.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make sure that you are
using it properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical to allow the
front air bags room to inflate.
6

22_VM_OM_EN_USC_t.book Page 137

138SAFETY
8. Do not lean against the door or window. If your vehicle has side air bags, and deployment
occurs, the side air bags will inflate forcefully
into the space between occupants and the
door and occupants could be injured.
9. If the air bag system in this vehicle needs to be modified to accommodate a disabled person,
see Úpage 242 for customer service contact
information.
SEAT BELT SYSTEMS
Buckle up even though you are an excellent driver,
even on short trips. Someone on the road may be
a poor driver and could cause a collision that
includes you. This can happen far away from home
or on your own street.
Research has shown that seat belts save lives, and
they can reduce the seriousness of injuries in a
collision. Some of the worst injuries happen when
people are thrown from the vehicle. Seat belts reduce
the possibility of ejection and the risk of injury caused
by striking the inside of the vehicle. Everyone in a
motor vehicle should be belted at all times.

Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver And Passenger BeltAlert — If Equipped
BeltAlert is a feature intended to remind
the driver and outboard front seat
passenger (if equipped with outboard
front passenger seat BeltAlert) to buckle
their seat belts. The BeltAlert feature is active
whenever the ignition switch is in the AVV/START
or MAR/RUN position.
Initial Indication

If the driver is unbuckled when the ignition switch is
first in the AVV/START or MAR/RUN position, a
chime will signal for a few seconds. If the driver or
outboard front seat passenger (if equipped with
outboard front passenger seat BeltAlert) is
unbuckled when the ignition switch is first in the
AVV/START or MAR/RUN position the Seat Belt
Reminder Light will turn on and remain on until both
outboard front seat belts are buckled. The outboard
front passenger seat BeltAlert is not active when an
outboard front passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when
the vehicle is moving above a specified vehicle
speed range and the driver or outboard front seat
passenger is unbuckled (if equipped with outboard
front passenger seat BeltAlert) (the outboard front
passenger seat BeltAlert is not active when the
outboard front passenger seat is unoccupied). The
BeltAlert warning sequence starts by blinking the
Seat Belt Reminder Light and sounding an
intermittent chime. Once the BeltAlert warning
sequence has completed, the Seat Belt Reminder
Light will remain on until the seat belts are
buckled. The BeltAlert warning sequence may
repeat based on vehicle speed until the driver and
occupied outboard front seat passenger seat belts
are buckled. The driver should instruct all
occupants to buckle their seat belts.
Change Of Status
If the driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) unbuckles their seat belt while the
vehicle is traveling, the BeltAlert warning sequence
will begin until the seat belts are buckled again.WARNING!
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.

22_VM_OM_EN_USC_t.book Page 138

SAFETY139
(Continued)
The outboard front passenger seat BeltAlert is not
active when the outboard front passenger seat is
unoccupied. BeltAlert may be triggered when an
animal or other items are placed on the outboard
front passenger seat or when the seat is folded flat
(if equipped). It is recommended that pets be
restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by seat
belts, and cargo is properly stowed.
BeltAlert can be activated or deactivated by an
authorized dealer. FCA US LLC does not
recommend deactivating BeltAlert.
NOTE:If BeltAlert has been deactivated and the driver or
outboard front seat passenger (if equipped with
outboard front passenger seat BeltAlert) is
unbuckled the Seat Belt Reminder Light will turn
on and remain on until the driver and outboard
front seat passenger seat belts are buckled.
Lap/Shoulder Belts
All seating positions in your vehicle are equipped
with lap/shoulder belts.
The seat belt webbing retractor will lock only during
very sudden stops or collisions. This feature allows
the shoulder part of the seat belt to move freely
with you under normal conditions. However, in a
collision the seat belt will lock and reduce your risk
of striking the inside of the vehicle or being thrown
out of the vehicle.
WARNING!
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, the air bags won’t
deploy at all. Always wear your seat belt even
though you have air bags.
In a collision, you and your passengers can
suffer much greater injuries if you are not
properly buckled up. You can strike the inte
-
rior of your vehicle or other passengers, or you
can be thrown out of the vehicle. Always be
sure you and others in your vehicle are
buckled up properly.
It is dangerous to ride in a cargo area, inside
or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seri -
ously injured or killed.
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and
seat belts.
Be sure everyone in your vehicle is in a seat
and using a seat belt properly. Occupants,
including the driver, should always wear their
seat belts whether or not an air bag is also
provided at their seating position to minimize
the risk of severe injury or death in the event
of a crash.
Wearing your seat belt incorrectly could make
your injuries in a collision much worse. You
might suffer internal injuries, or you could
even slide out of the seat belt. Follow these
instructions to wear your seat belt safely and
to keep your passengers safe, too.
Two people should never be belted into a
single seat belt. People belted together can
crash into one another in a collision, hurting
one another badly. Never use a lap/shoulder
belt or a lap belt for more than one person, no
matter what their size.

How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and
allow it to retract completely to disengage the
Automatic Locking Mode and activate the vehicle
sensitive (emergency) locking mode.
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
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 AVV/START or
MAR/ACC/ON/RUN position. If the ignition switch
is in the STOP/OFF/LOCK 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
in the MAR/ACC/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.
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 immediately.The Air Bag Warning Light does not come on
during the four to eight seconds when the igni
-
tion switch is first in the MAR/ACC/ON/RUN
position.
The Air Bag Warning Light remains on after the
four to eight-second interval.
The Air Bag Warning Light comes on intermit -
tently or remains on while driving.
WARNING!
The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR)
feature or any other seat belt function is not
working properly when checked according to
the procedures in the Service Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in collisions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the seat
belt or children who are using booster seats.
The locked mode is only used to install
rear-facing or forward-facing child restraints
that have a harness for restraining the child.
