and parking time).
• The vehicle should have service performed if the mes-
sage is still present during consecutive trips and the
evaluation of the vehicle and driving pattern did not
help to identify the cause.
WARNING LIGHTS AND MESSAGES
Red Warning Lights
— Seat Belt Reminder Warning Light
This light indicates when the driver or passenger seat belt
is unbuckled. When the ignition is first placed in the
ON/RUN or ACC/ON/RUN position and if the driver ’s
seat belt is unbuckled, a chime will sound and the light will
turn on. When driving, if the driver or front passenger seat
belt remains unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime will sound.
Refer to “Occupant Restraints Systems” in “Safety” for
further information.
— Air Bag Warning Light
This light indicates a fault with the air bag, and will turn on
for four to eight seconds as a bulb check when the ignition
is placed in the ON/RUN or ACC/ON/RUN position. This light will illuminate with a single chime when a fault
with the air bag has been detected, it will stay on until the
fault is cleared. If the light is either not on during startup,
stays on, or turns on while driving, have the system
inspected at an authorized dealer as soon as possible.
— Brake Warning Light
This light monitors various brake functions, including
brake fluid level and parking brake application. If the
brake light turns on it may indicate that the parking brake
is applied, that the brake fluid level is low, or that there is
a problem with the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition has
been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake,
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity
in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is

indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level conditions.
The vehicle should have service performed, and the brake
fluid level checked.
If brake failure is indicated, immediate repair is necessary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by your authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.
— Vehicle Security Warning Light — If Equipped
This light will flash at a fast rate for approximately 15
seconds when the vehicle security alarm is arming, and
then will flash slowly until the vehicle is disarmed.
— Engine Coolant Temperature Warning Light
This light warns of an overheated engine condition. If the
engine coolant temperature is too high, this indicator will
illuminate and a single chime will sound. If the tempera-
ture reaches the upper limit, a continuous chime will be
sound for four minutes or until the engine is able to cool:
whichever comes first.
If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift

Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
•ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
For further information, refer to “Cybersecurity” in “Mul-
timedia”.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration. For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not on
when the engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not ready
for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle’s OBD II system is ready, you must do the follow-
ing:
1. Cycle the ignition switch to the ON position, but do not crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.

OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your vehicle
are the restraint systems:
Occupant Restraint Systems Features
• 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 your autho-
rized 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 a vehicle with a rear seat.
2. 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 (refer to “Child Restraints” in this section for
further information).
3. Children that are not big enough to wear the vehicle seat belt properly (refer to “Child Restraints” in this section
for further information) should be secured in a vehicle
with a rear seat in child restraints or belt-positioning
booster seats. Older children who do not use child
restraints or belt-positioning booster seats should ride
properly buckled up in a vehicle with a rear seat.
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.

a few seconds. If the driver or outboard front seat passen-
ger (if equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition switch is first in
the START or ON/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 unbuck-
led (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 buck-
led again.
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 your autho-
rized dealer. FCA US LLC does not recommend deactivat-
ing 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.

Switchable Automatic Locking Retractors (ALR)
The seat belts in the passenger seating positions are
equipped with a Switchable Automatic Locking Retractor
(ALR) which is used to secure a child restraint system. For
additional information, refer to “Installing Child Restraints
Using The Vehicle Seat Belt” under the “Child Restraints”
section of this manual. The figure below illustrates the
locking feature for each seating position.If the passenger seating position is equipped with an ALR
and is being used for normal usage, only pull the seat belt
webbing out far enough to comfortably wrap around the
occupant’s mid-section so as to not activate the ALR. If the
ALR is activated, you will hear a clicking sound as the seat
belt retracts. Allow the webbing to retract completely in
this case and then carefully pull out only the amount of
webbing necessary to comfortably wrap around the occu-
pant’s mid-section. Slide the latch plate into the buckle
until you hear aclick.

dealer. Only manufacturer approved seat accessories
may be used. If it is necessary to modify the air bag
system for persons with disabilities, contact 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.
204 SAFETY

Older Children And Child Restraints
Children who are two years old or who have outgrown
their rear-facing convertible child seat can ride forward-
facing in the vehicle. Forward-facing child seats and con-
vertible child seats used in the forward-facing direction are
for children who are over two years old or who have
outgrown the rear-facing weight or height limit of their
rear-facing convertible child seat. Children should remain
in a forward-facing child seat with a harness for as long as
possible, up to the highest weight or height allowed by the
child seat.
All children whose weight or height is above the forward-
facing limit for the child seat should use a belt-positioning
booster seat until the vehicle’s seat belts fit properly. If the
child cannot sit with knees bent over the vehicle’s seat
cushion while the child’s back is against the seatback, they
should use a belt-positioning booster seat. The child and
belt-positioning booster seat are held in the vehicle by the
seat belt.
WARNING!
•Improper installation can lead to failure of an infant
or child restraint. It could come loose in a collision.
The child could be badly injured or killed. Follow
the child restraint manufacturer ’s directions exactly
when installing an infant or child restraint.
• After a child restraint is installed in the vehicle, do
not move the vehicle seat forward or rearward be-
cause it can loosen the child restraint attachments.
Remove the child restraint before adjusting the ve-
hicle seat position. When the vehicle seat has been
adjusted, reinstall the child restraint.
• When your child restraint is not in use, secure it in
the vehicle with the seat belt or LATCH anchorages,
or remove it from the vehicle. Do not leave it loose in
the vehicle. In a sudden stop or accident, it could
strike the occupants or seatbacks and cause serious
personal injury.
