tower, airport transmitter, and some mobile or CB
radios.
REMOTE STARTING SYSTEM — IF EQUIPPED

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 the RKE trans-
mitter may reduce this range.

•Supplemental Restraint Systems (SRS) Air Bags
•Supplemental Active Head Restraints
•Child Restraints
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”)3. Children that are not big enough to wear the vehicle
seat belt properly (Refer toChild Restraints) should
be secured in a vehicle with a rear seat in child
restraints or belt-positioning booster seats. Older chil-
dren 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.
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 Advanced Front
Air Bags room to inflate.

the START or ON/RUN position. If the driver or
outboard front seat passenger is unbelted, the Seat Belt
Reminder Light will turn on and remain on until both
outboard front seat belts are buckled.
The BeltAlert warning 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 seat belts are buckled.
After the sequence completes, the Seat Belt Reminder
Light remains illuminated until the respective seat belts
are buckled. The driver should instruct all other occu-
pants to buckle their seat belts. If an outboard 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 outboard front passenger seat BeltAlert is not active
when the outboard front passenger seat is unoccupied.BeltAlert may be triggered when an animal or heavy
object is 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 deacti-
vating BeltAlert.
NOTE:If BeltAlert has been deactivated, the Seat Belt
Reminder Light will continue to illuminate while the
driver ’s or outboard front passenger ’s (if equipped with
BeltAlert) seat belt remains unbuckled.
Lap/Shoulder Belts
All seating positions in your vehicle are equipped with
lap/shoulder belts.
