correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the “Tire Pressure Monitor-
ing Telltale Light”.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
NOTE: It is particularly important for you to check the
tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure. The TPMS consists of the following components:
•
Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, a “LOW TIRE
PRESSURE” message will display in the instrument
cluster, an Inflate to XX message will be displayed and
a chime will sound when tire pressure is low in one or
more of the four active road tires. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire
to the vehicle’s recommended cold placard pressure
value as shown in the Inflate to XXmessage. Once the
296 SAFETY

system receives the updated tire pressures, the system
will automatically update and the “Tire Pressure Moni-
toring Telltale Light” will turn off.
NOTE:When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
The vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to receive
this information.
Service TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. The system fault will
also sound a chime. If the ignition is cycled, this sequence
will repeat, providing the system fault still exists. The “Tire Pressure Monitoring Telltale Light” will turn off
when the fault condition no longer exists. A system fault
can occur due to any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare
1. The compact spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not moni-
tor the pressure in the compact spare tire.

SAFETY 297

2. If you install the compact or non-matching full sizespare tire in place of a road tire that has a pressure
below the low-pressure warning limit, a chime will
sound and the “TPMS Telltale Light” and “LOW TIRE
PRESSURE” and Inflate to XXmessages will turn on
upon the next ignition cycle.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the “TPMS Telltale Light” will
flash on and off for 75 seconds and then remain on
solid.
4. For each subsequent ignition cycle, a chime will sound and the “TPMS Telltale Light” will flash on and off for
75 seconds and then remain on solid.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare
or non-matching full size spare, the TPMS will update
automatically and the “TPMS Telltale Light” will turn off, as long as no tire pressure is below the low-
pressure warning limit in any of the four active road
tires. The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.

above 15 mph (24 km/h) in order for the TPMS to receive
this information.
Service TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. The system fault will
also sound a chime. In addition, the EVIC/DID will
display aSERVICE SYSTEM message for a minimum of
five seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.
If the ignition is cycled, this sequence will repeat, pro-
viding the system fault still exists. If the system fault no longer exists, the “Tire Pressure Monitoring Telltale
Light” will no longer flash, and the “SERVICE SYSTEM
message will no longer display, and a pressure value will
display in place of the dashes. A system fault can occur
due to any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.

Vehicles With Compact Spare
1. The compact spare tire does not have a tire pressuremonitoring sensor. Therefore, the TPMS will not moni-
tor the pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition cycle, the “TPMS
Telltale Light” will remain on and a chime will sound.
In addition, the graphic in the EVIC/DID will still
display a different color pressure value and an Inflate
to XX message.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the “TPMS Telltale Light” will
flash on and off for 75 seconds and then remain on
solid. In addition, the EVIC/DID will display a “SER-
VICE SYSTEM” message for five seconds and then
display dashes (- -) in place of the pressure value. 4. For each subsequent ignition cycle, a chime will
sound, the “TPMS Telltale Light” will flash on and off
for 75 seconds and then remain on solid, and the
EVIC/DID will display a “SERVICE SYSTEM” mes-
sage for five seconds and then display dashes (- -) in
place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
“TPMS Telltale Light” will turn off and the graphic in
the EVIC/DID will display a new pressure value
instead of dashes (- -), as long as no tire pressure is
below the low-pressure warning limit in any of the
four active road tires. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this information.

position the Seat Belt Reminder Light will turn on and
remain on until both outboard front seat belts are buck-
led. The outboard front passenger seat BeltAlert is not
active when an outboard front passenger seat is unoccu-
pied.
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 un-
buckled (if equipped with outboard front passenger seat
BeltAlert). 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 thedriver and occupied outboard front seat passenger seat
belts are buckled. The driver should instruct all occu-
pants 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.

SAFETY 305

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 and the driver
or outboard front seat passenger (if equipped with out-
board front passenger seat BeltAlert) is unbuckled the
Seat Belt Reminder Light will turn on and remain on until
the driver and outboard front seat passenger seat belts
are buckled.
Lap/Shoulder Belts
All seating positions in your vehicle are equipped with
lap/shoulder belts.
The seat belt webbing retractor will lock only during very
sudden stops or collisions. This feature allows the shoul-
der part of the seat belt to move freely with you under
normal conditions. However, in a collision the seat belt will lock and reduce your risk of striking the inside of the
vehicle or being thrown out of the vehicle.
WARNING!
•
Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work
with your seat belt to restrain you properly. In
some collisions, the air bags won’t deploy at all.
Always wear your seat belt even though you have
air bags.
• In a collision, you and your passengers can suffer
much greater injuries if you are not properly buck-
led up. You can strike the interior of your vehicle or
other passengers, or you can be thrown out of the
vehicle. Always be sure you and others in your
vehicle are buckled up properly.

WARNING!
•The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR) fea-
ture or any other seat belt function is not working
properly when checked according to the proce-
dures in the Service Manual.
• Failure to replace the seat belt assembly could
increase the risk of injury in collisions.
• Do not use the Automatic Locking Mode to restrain
occupants who are wearing the seat belt or children
who are using booster seats. The locked mode is
only used to install rear-facing or forward-facing
child restraints that have a harness for restraining
the child.

located in the front passenger seat
• Air Bag Warning Light
Occupant Classification Module (OCM) and Sensor
The Occupant Classification Module (OCM) is located
underneath the front passenger seat. The Sensor is lo-
cated beneath the passenger seat cushion foam. Any
weight on the seat will be sensed by the Sensor. The OCM
uses input from the Sensor to determine the front pas-
senger ’s most probable classification. The OCM commu-
nicates this information to the ORC. The ORC may
reduce the inflation rate of the Passenger Advanced Front
Air Bag deployment based on occupant classification. In
order for the OCS to operate as designed, it is important
for the front passenger to be seated properly and prop-
erly wearing the seat belt. The OCS will NOT prevent deployment of the Passenger
Advanced Front Air Bag. The OCS may reduce the
inflation rate of the Passenger Advanced Front Air Bag if
the OCS estimates that:
•
The front passenger seat is unoccupied or has very
light objects on it; or
• The front passenger seat is occupied by a small pas-
senger, including a child; or
• The front passenger seat is occupied by a rear-facing
child restraint; or
• The front passenger is not properly seated or his or her
weight is taken off of the seat for a period of time.
