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 approximately 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 an 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 warning 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 temperature
reaches the upper limit, a continuous chime will
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 Air Conditioning (A/
C) system is on, turn it off. Also, shift the
transmission into NEUTRAL and idle the vehicle.
If the temperature reading does not return to
normal, turn the engine off immediately and call
for service.
Refer to “If Your Engine Overheats” in “In Case
Of Emergency” for further information.
Battery Charge Warning Light
This warning light will illuminate when
the battery is not charging properly. If
it stays on while the engine is running,
there may be a malfunction with the
charging system. Contact an authorized dealer
as soon as possible.
This indicates a possible problem with the
electrical system or a related component.
Oil Pressure Warning Light
This warning light will illuminate to
indicate low engine oil pressure. If the
light turns on while driving, stop the
vehicle, shut off the engine as soon as
possible, and contact an authorized dealer. A
chime will sound when this light turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.

BLUE INDICATOR LIGHTS
High Beam Indicator Light
This indicator light will illuminate to
indicate that the high beam
headlights are on. With the low beams
activated, push the multifunction
lever forward (toward the front of the vehicle) to
turn on the high beams.
Pull the multifunction lever rearward (toward
the rear of the vehicle) to turn off the high
beams. If the high beams are off, pull the lever

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II. This
system monitors the performance of the
emissions, engine, and transmission control
systems. When these systems are operating
properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current
government regulations. If any of these systems require service, the
OBD II system will turn on the Malfunction
Indicator Light (MIL). It will also store diagnostic
codes and other information to assist your
service technician in making repairs. Although
your vehicle will usually be drivable and not
need towing, see an authorized dealer for
service as soon as possible.
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
access this information to assist with the
diagnosis and service of your vehicle and
emissions system.
For further information, refer to “Cybersecurity”
in “Multimedia”.
CAUTION!
Prolonged driving with the MIL on could
cause further damage to the emission
control system. It could also affect fuel
economy and driveability. The vehicle must
be serviced before any emissions tests can
be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
WARNING!
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
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 acci
-
dent involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
including personal information.

2. A child who is not big enough to wear the
vehicle seat belt properly (refer to “Child
Restraints” in this section for further
information) must be secured in the
appropriate child restraint or
belt-positioning booster seat in a rear
seating position.
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. (Refer to “Child Restraints” in this
section for further information).
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. 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, refer to the “Customer Assistance”
section 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.
Vehicles Without Passenger Seating
Installed
If your vehicle does not have a factory installed
front passenger seat and/or rear passenger
seats, the features described in this section
may not be available in your vehicle.
This vehicle has been designed to maximize
total performance. The passenger seats may be
deleted, which may affect the NVH (Noise,
Vibration, and Harshness) characteristics. As a
result, the vehicle may be louder overall.
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.

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 START or ON/RUN position.
Initial Indication
If the driver is unbuckled when the ignition
switch is first in the START or ON/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 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 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.
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.
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 positions to
minimize the risk of severe injury or death
in the event of a crash.
All occupants, including the driver, should
not operate a vehicle or sit in a vehicle’s
seat if the head restraints are not in place
of their proper positions in order to mini
-
mize the risk of neck injury in the event of a
crash.
Head restraints should never be adjusted
while the vehicle is in motion. Driving a
vehicle with the head restraints improperly
adjusted or removed could cause serious
injury or death in the event of a collision.

Energy Management Feature
The front outboard seat belt system is equipped
with an Energy Management feature that may
help further reduce the risk of injury in the event
of a collision. The seat belt system has a
retractor assembly that is designed to release
webbing in a controlled manner.
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.

Retractor (ALR) Locations

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
occupant’s mid-section. Slide the latch plate
into the buckle until you hear a "click."ALR — Switchable Automatic Locking Retractor

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.
Children 12 years or younger should ride
properly buckled up in a rear seat, if available.
According to crash statistics, children are safer
when properly restrained in the rear seats
rather than in the front.
If your vehicle is not equipped with a rear seat,
FCA US LLC recommends that you do not allow
children 12 years old and under to ride in your
vehicle. If the rear seats are not present in your
vehicle, NEVER install a child restraint in these
positions. There are different sizes and types of restraints
for children from newborn size to the child
almost large enough for an adult safety belt.
Always check the child seat Owner’s Manual to
make sure you have the correct seat for your
child. Carefully read and follow all the
instructions and warnings in the child restraint
Owner’s Manual and on all the labels attached
to the child restraint.Before buying any restraint system, make sure
that it has a label certifying that it meets all
applicable Safety Standards. You should also
make sure that you can install it in the vehicle
where you will use it.

WARNING!
In a collision, an unrestrained child can
become a projectile inside the vehicle. The
force required to hold even an infant on your
lap could become so great that you could not
hold the child, no matter how strong you are.
The child and others could be badly injured or
killed. Any child riding in your vehicle should
be in a proper restraint for the child’s size.

Summary Of Recommendations For Restraining Children In Vehicles
NOTE:
If your vehicle is not equipped with a rear seat, FCA US LLC recommends that you do not allow children 12 years old and under to ride in your vehicle.
If the rear seats are not present in your vehicle, NEVER install a child restraint in these positions. If you must install a forward facing child restraint in
the front passenger seat, then you must use the seat belt system to secure the restraint. A top tether strap extension may be needed to reach the tether
anchor on the rear shelf directly behind the passenger seat.
Child Size, Height, Weight Or Age Recommended Type Of Child Restraint
Infants and Toddlers Children who are two years old or younger and
who have not reached the height or weight limits
