REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
•The vehicle must be equipped with an automatic
transmission to be equipped with Remote Start.
•Obstructions between the vehicle and RKE transmitter
may reduce this range.

OCCUPANT RESTRAINTS
Some of the most important safety features in your
vehicle are the restraint systems:
•Three-point lap and shoulder belts for the driver and
all passengers
•Advanced Front Air Bags for driver and front passen-
ger
•Supplemental Seat-Mounted Side Air Bags (SAB) — if
equipped
•An energy-absorbing steering column and steering
wheel
•Knee bolsters/blockers for front seat occupants
•Front seat belts incorporate pretensioners that may
enhance occupant protection by managing occupant
energy during an impact event
•All seat belt systems (except the driver’s) include
Automatic Locking Retractors (ALRs), which lock the
seat belt webbing into position by extending the belt
all the way out and then adjusting the belt to the
desired length to restrain a child seat or secure a large
item in a seat — if equipped
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.
If you will be carrying children too small for adult-sized
seat belts, the seat belts or the Lower Anchors and Tether
for CHildren (LATCH) feature also can be used to hold
infant and child restraint systems. For more information
on LATCH, refer to Lower Anchors and Tether for
CHildren (LATCH).

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 43

NOTE:The Advanced Front Air Bags have a multistage
inflator design. This allows the air bag to have different
rates of inflation based on several factors, including the
severity and type of collision.
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 rear seat.
WARNING!
Infants in rear facing child restraints should never
ride in the front seat of a vehicle with a passenger
Advanced Front Air Bag. An air bag deployment can
cause severe injury or death to infants in that posi-
tion.
Children that are not big enough to wear the vehicle seat
belt properly (see section on Child Restraints) should be secured in the 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. Never allow
children to slide the shoulder belt behind them or under
their arm.
If a child from 1 to 12 years old (not in a rear facing child
seat) 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”)
You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2.
All occupants should always wear their lap and
shoulder belts properly.
3. The driver and front passenger seats should be
moved back as far as practical to allow the Advanced
Front Air Bags room to inflate.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Seat Belts In Passenger Seating Positions
The seat belts in the passenger seating positions are
equipped with Automatic Locking Retractors (ALR)
which are used to secure a child restraint system. For
additional information, refer to “Installing Child Re-
straints Using The Vehicle Seat Belt” under the “Child
Restraints” section. The chart below defines the type of
feature for each seating position.
Driver Center Passenger
First Row N/A N/A ALR
Second Row ALR ALR ALR
•N/A — Not Applicable
•ALR — Automatic Locking Retractor
If the passenger seating position is equipped with an
ALR and is being used for normal usage:
Only pull the 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
ratcheting sound as the belt retracts. Allow the webbing
to retract completely in this case and then carefully pull
out only the amount of webbing necessary to comfort-
ably wrap around the occupant’s mid-section. Slide the
latch plate into the buckle until you hear a
click.
Automatic Locking Retractor Mode (ALR) — If
Equipped
In this mode, the shoulder belt is automatically pre-
locked. The belt will still retract to remove any slack in
the shoulder belt. The Automatic Locking Mode is avail-
able on all passenger-seating positions with a combina-
tion lap/shoulder belt. Use the Automatic Locking Mode
anytime a child safety seat is installed in a seating
position that has a belt with this feature. Children
12 years old and under should always be properly
restrained in the rear seat.
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The BeltAlertwarning sequence begins after the vehicle
speed is over 5 mph (8 km/h), by blinking the Seat Belt
Reminder Light and sounding an intermittent chime.
Once the sequence starts, it will continue for the entire
duration or until the respective seatbelts are fastened.
After the sequence completes, the Seat Belt Reminder
Light remains illuminated until the respective seat belts
are fastened. The driver should instruct all other occu-
pants to fasten their seat belts. If a front seat belt is
unbuckled while traveling at speeds greater than 5 mph
(8 km/h), BeltAlert will provide both audio and visual
notification.
The front passenger seat BeltAlert is not active when the
front passenger seat is unoccupied. BeltAlert may be
triggered when an animal or heavy object is on the front
passenger seat or when the seat is folded flat (if
equipped). It is recommended that pets be restrained in
the rear seat in pet harnesses or pet carriers that are
secured by seat belts, and cargo is properly stowed. BeltAlert
can be enabled or disabled by your authorized
dealer. Chrysler Group LLC does not recommend deac-
tivating BeltAlert.
NOTE: Although BeltAlert has been deactivated, the
Seat Belt Reminder Light will continue to illuminate
while the driver ’s or front passenger (if equipped with
BeltAlert) seat belt remains unfastened.
Seat Belts And Pregnant Women
We recommend that pregnant women use seat belts
throughout their pregnancy. Keeping the mother safe is
the best way to keep the baby safe.
Pregnant women should wear the lap part of the belt
across the thighs and as snug across the hips as possible.
Keep the belt low so that it does not come across the
abdomen. That way the strong bones of the hips will take
the force if there is a collision.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 57

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 equip-
ment, 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 all Canadian provinces require that
small children ride in proper restraint systems. This is the
law, and you can be prosecuted for ignoring it.
Children 12 years or under 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.
There are different sizes and types of restraints for
children from newborn size to the child almost largeenough for an adult safety belt. Always check the child
seat owner’s manual to ensure you have the correct seat
for your child. Use the restraint that is correct for your
child.
WARNING!
In a collision, an unrestrained child, even a tiny baby,
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. Any child riding in your
vehicle should be in a proper restraint for the child’s
size.
Infants And Child Restraints
Safety experts recommend that children ride rearward-
facing in the vehicle until they are two years old or until
they reach either the height or weight limit of their rear
