Preventing Inadvertent Locking Of Passive Entry
Key Fob In Vehicle (FOBIK-Safe)
To minimize the possibility of unintentionally
locking a Passive Entry key fob inside your
vehicle, the Passive Entry system is equipped
with an automatic door unlock feature which
will function if the ignition switch is in the
OFF position.
FOBIK-Safe only executes in vehicles with
passive entry. There are five situations that
trigger a FOBIK-Safe search in any passive
entry vehicle:
• A lock request is made by a valid Passive
Entry key fob while a door is open.
• A lock request is made by the Passive Entry
door handle while a door is open.
• A lock request is made by the door panel
switch while the door is open.
• When the vehicle security alarm is in pre-
arm or armed status and the liftgate transi-
tions from open to closed.
• When the liftgate transitions from opened
to closed and remote start is active.When any of these situations occur, after all
open doors are shut, the FOBIK-Safe search
will be executed. If it finds a Passive Entry
key fob inside the car, the car will unlock and
alert the customer.
NOTE:
The vehicle will only unlock the doors when a
valid Passive Entry key fob is detected inside
the vehicle. The vehicle will not unlock the
doors when any of the following conditions
are true:
• The doors are manually locked using the
door lock knobs.
• Three attempts are made to lock the doors
using the door panel switch and then close
the doors.
• There is a valid Passive Entry key fob out-
side the vehicle within 5 ft. (1.5 m) of a
Passive Entry door handle.
• If the keys are left in the vehicle while the
liftgate is opened, and all four doors are
then locked, closing the liftgate will lock
the keys within the vehicle.To Lock The Vehicle’s Doors And Liftgate
With one of the vehicle’s Passive Entry key
fob within 5 ft (1.5 m) of the driver or
passenger front door handles, pushing the
passive entry lock button will lock the ve-
hicle.
NOTE:
DO NOT grab the door handle, when pushing
the door handle lock button. This could un-
lock the door(s).

Anti-Pinch Safety Device
This feature will detect an obstruction in the
opening of the sunroof during Express Close
operation. If an obstruction in the path of the
sunroof is detected, the sunroof will auto-
matically retract. Remove the obstruction if
this occurs. Next, push the switch forward
and release to Express Close.
NOTE:
If three consecutive sunroof close attempts
result in Pinch Protect reversals, the fourth
close attempt will be a Manual Close move-
ment with Pinch Protect disabled.
WARNING!
• Do not let children play with the sunroof.
Never leave children unattended in a
vehicle, or with access to an unlocked
vehicle. Do not leave the key fob in or
near the vehicle, and do not leave the
ignition of a vehicle equipped with Key-
less Enter-N-Go in the ACC or ON/RUN
mode. Occupants, particularly unat-
tended children, can become entrapped
by the power sunroof while operating the
WARNING!
power sunroof switch. Such entrapment
may result in serious injury or death.
• In a collision, there is a greater risk of
being thrown from a vehicle with an
open sunroof. You could also be severely
injured or killed. Always fasten your seat
belt properly and make sure all passen-
gers are properly secured.
• Do not allow small children to operate
the sunroof. Never allow your fingers,
other body parts, or any object to project
through the sunroof opening. Injury may
result.

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 govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the Malfunction
Indicator Light (MIL). It will also store diag-
nostic 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.
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 dam-
age and power loss will soon occur. Im-
mediate service is required.
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.
WARNING!
• ONLY an authorized service technician
should connect 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 ve-
hicle control could occur that may
result in an accident involving seri-
ous injury or death.
• Access, or allow others to access,
information stored in your vehicle
systems, including personal infor-
mation.
For further information, refer to “Cybersecu-
rity” in “Multimedia”.

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 fur-
ther information) should be secured in therear seat of 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 the
rear seat of 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.
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 deploy-
ment occurs, the side air bags will inflate
forcefully into the space between occu-
pants and the door and occupants could
be injured.9. If the air bag system in this vehicle needs
to be modified to accommodate a dis-
abled person, refer to the “Customer As-
sistance” section for customer service
contact information.
WARNING!
• NEVER use a rearward facing child re-
straint on a seat protected by an ACTIVE
AIRBAG in front of it, DEATH or SERI-
OUS INJURY to the CHILD can occur.
• Only use a rear-facing child restraint in
the rear seat of a vehicle with a rear seat.
• 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.
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.

SAFETY
100

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
Belt Alert feature is active whenever the igni-
tion switch is in the START or ON/RUN posi-
tion.
Initial Indication
If the driver is unbuckled when the ignition
switch is first in the START or ON/RUN posi-
tion, 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 ignitionswitch is first in the START or ON/RUN posi-
tion the Seat Belt Reminder Light will turn on
and remain on until both outboard front seat
belts are buckled. The outboard front passen-
ger seat BeltAlert is not active when an out-
board 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 out-
board 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 passen-
ger 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 authorized dealer. FCA US LLC does not
recommend deactivating BeltAlert.
