be belted at all times.
Enhanced Seat Belt Use Reminder System
(BeltAlert®)
BeltAlert® is a feature intended to remind the
driver and outboard front passenger (if equipped with
outboard front passenger BeltAlert®) to buckle their
seat belts. The feature is active whenever the ignition
switch is in 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 unoc-
cupied. 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 recom-
mended that pets be restrained in the rear seat (if
equipped) in pet harnesses or pet carriers that are se-
cured by seat belts, and cargo is properly stowed.
BeltAlert® can be activated or deactivated by your au-
thorized dealer. Chrysler Group LLC does not recom-
mend deactivating BeltAlert®.

System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition
OFF.
Air Bag Warning Light
The air bags must be ready to inflate for your protection
in a collision. The Occupant Restraint Control-
ler (ORC) monitors the internal circuits and
interconnecting wiring associated with air bag
system electrical components.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
START or ON/RUN position. If the ignition switch is in
the OFF position or in the ACC position, the air bag
system is not on and the air bags will not inflate.
The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first turned to
the ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a mal-
function in any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continuously. A
single chime will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will illuminate
the instrument panel Air Bag Warning Light if a malfunc-
tion is detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.
While the air bag system is designed to be maintenance

free, if any of the following occurs, have an authorized
dealer service the air bag system immediately.
•The Air Bag Warning Light does not come on during
the four to eight seconds when the ignition switch is
first turned to the ON/RUN position.
•The Air Bag Warning Light remains on after the four to
eight-second interval.
•The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protec-
tion. Have an authorized dealer service the air bag
system immediately.
WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
to protect you in a collision. If the light does not come
on as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
air bag system immediately.
80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag system
could cause it to fail when you need it. You could
be injured if the air bag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or the
upper right side of the instrument panel. Do not
modify the front bumper, vehicle body structure, or
add aftermarket side steps or running boards.
•It is dangerous to try to repair any part of the air
bag system yourself. Be sure to tell anyone who
works on your vehicle that it has an air bag system.
(Continued)
WARNING!(Continued)
•Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made.

The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
13. Fuel Gauge/Fuel Door Reminder
The fuel pump symbol points to the side of the vehicle
where the fuel door is located. The pointer shows the
level of fuel in the fuel tank when the ignition switch is in
the ON/RUN position.
14. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.

Air Suspension Modes
The Air Suspension system has multiple modes to protect
the system in unique situations:
Tire/Jack Mode
To assist with changing a spare tire, the air suspension
system has a feature which allows the automatic leveling
to be disabled. Refer to “Uconnect® Settings” in “Under-
standing Your Instrument Panel” for further information.
NOTE:This mode is intended to be enabled with engine
running.
Transport Mode
To assist with flat bed towing, the air suspension system
has a feature which will put the vehicle into Entry/Exit
height and disable the automatic load leveling system.
Refer to “Uconnect® Settings” in “Understanding Your
Instrument Panel” for further information.
NOTE:This mode is intended to be enabled with engine
running.
Wheel Alignment Mode
Before performing a wheel alignment this mode must be
enabled. Refer to “Uconnect® Settings” in “Understand-
ing Your Instrument Panel” for further information.
NOTE:This mode is intended to be enabled with engine
running.
If equipped with a touch screen radio all enabling/
disabling of air suspension features must be done
through the radio. Refer to “Uconnect® Settings” in
“Understanding Your Instrument Panel” for further in-
formation.
454 STARTING AND OPERATING

WARNING!
Significant over or under-inflation of tires, or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.
The Anti-Lock Brake System conducts a low speed self-
test at about 12 mph (20 km/h). If for any reason your
foot is on the brake when the vehicle reaches 12 mph
(20 km/h), this check will be delayed until 25 mph
(40 km/h).
The Anti-Lock Brake System pump motor runs during
the self-test, and during an ABS stop, to provide the
regulated hydraulic pressure. The motor pump makes a
low humming noise during operation; this is normal.
WARNING!
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
•The Anti-Lock Brake System (ABS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can they increase braking or steering
efficiency beyond that afforded by the condition of
the vehicle brakes and tires or the traction afforded.
•The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
•The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or
the safety of others.
474 STARTING AND OPERATING

Tire Repair
If your tire becomes damaged, it may be repaired if it
meets the following criteria:
•The tire has not been driven on when flat.
•The damage is only on the tread section of your tire
(sidewall damage is not repairable).
•The puncture is no greater than¼#(6 mm).
Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced imme-
diately with another Run Flat tire of identical size and
service description (Load Index and Speed Symbol).
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons (spring,
summer, fall and winter). Traction levels may vary be-
tween different all season tires. All season tires can be
identified by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Summer Or Three Season Tires — If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in snow or
on ice. If your vehicle is equipped with summer tires, be
aware these tires are not designed for winter or cold
driving conditions. Install winter tires on your vehicle
when ambient temperatures are less than 40°F (5°C) or if
roads are covered with ice or snow. For more informa-
tion, contact an authorized dealer.
