2. Installing some form of aftermarket window tinting thataffects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
The instrument cluster will also display a SERVICE TPM
SYSTEM message for a minimum of five seconds when a
system fault related to an incorrect sensor location fault is
detected. In this case, the SERVICE TPM SYSTEM mes-
sage is then followed with a graphic display with pressure
values still shown. This indicates that the pressure values
are still being received from the TPM sensors but they may
not be located in the correct vehicle position. The system
still needs to be serviced as long as the SERVICE TPM
SYSTEM message is displayed.
NOTE: Your vehicle is equipped with a compact spare
wheel and tire assembly.
1. The compact spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not moni-
tor the tire 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 warning limit, upon the next ignition key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
will still turn ON due to the low tire. The “LOW TIRE”
text message and the graphic with the low tire pressure
flashing will be displayed.
3. However, after driving the vehicle for up to 10 minutes above 15 mph (24 km/h), the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid. In addition, the instrument cluster
will display a “SERVICE TPM SYSTEM” message for a
minimum of five seconds and then display dashes (- -)
in place of the pressure values.
4. For each subsequent ignition key cycle, a chime will sound and the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on
solid, and the instrument cluster will display a “SER-
VICE TPM SYSTEM” message for a minimum of five
seconds and then display dashes (- -) in place of the
pressure values.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare
tire, the TPMS will update automatically and the Tire
Pressure Monitoring Telltale Light will turn OFF, as long
as no tire pressure is below the low-pressure warning

Resetting Active Head Restraints (AHR)
If the Active Head Restraints are triggered during a colli-
sion, the front half of the head restraint will be extended
forward and separated from the rear half of the head
restraint (See Image). Do not drive your vehicle after the
AHRs have deployed. The head restraint must be reset into
the original position to best protect the occupant for all
types of collisions. An authorized FCA US LLC dealer must
reset the AHRs on the driver ’s and front passenger ’s seat
before driving. Personally attempting to reset the AHRs
may result in damage to the AHRs that could impair their
function.
WARNING!
Deployed AHRs are not able to best protect you in all
types of collisions. Have deployed AHRs reset by an
authorized dealer immediately.
Supplemental Restraint System (SRS)
Some of the safety features described in this section may be
standard equipment on some models, or may be optional
equipment on others. If you are not sure, ask your autho-
rized dealer.The air bag system must be ready to protect you in a
collision. The Occupant Restraint Controller (ORC) moni-
tors the internal circuits and interconnecting wiring asso-
ciated with the electrical Air Bag System Components.
Your vehicle may be equipped with the following Air Bag
System Components:

WARNING!(Continued)
•Never place a rear-facing child restraint in front of an
air bag. 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.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
Driver and Passenger Front Air Bag Features
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as deter-
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors (if
equipped) or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether the driver or front passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of the Ad-
vanced Front Air Bags.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
WARNING!
•
No objects should be placed over or near the air bag
on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.
• Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
the air bags and you could be injured because the air
bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.
• 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

WARNING!(Continued)
collisions, air bags won’t deploy at all. Always wear
your seat belts even though you have air bags.
Front Air Bag Operation
Front Air Bags are designed to provide additional protec-
tion by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions. The front air bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not
good indicators of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in all collisions,
and also are needed to help keep you in position, away
from an inflating air bag. When the ORC detects a collision requiring the front air
bags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air bags.
The steering wheel hub trim cover and the upper right side
of the instrument panel separate and fold out of the way as
the air bags inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your eyes. The
front air bags then quickly deflate while helping to restrain
the driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passenger, and position the front occu-
pants for improved interaction with the front air bags.
WARNING!
•
Do not drill, cut, or tamper with the knee impact
bolsters in any way.
• Do not mount any accessories to the knee impact
bolsters such as alarm lights, stereos, citizen band
radios, etc.

SAFETY 167

Side Air Bags are a supplement to the seat belt restraint
system. Side Air Bags deploy in less time than it takes to
blink your eyes.
WARNING!
•Occupants, including children, who are up against or
very close to SABICs can be seriously injured or
killed. Occupants, including children, should never
lean on or sleep against the door, side windows, or
area where the side air bags inflate, even if they are
in an infant or child restraint.
• Seat belts (and child restraints where appropriate)
are necessary for your protection in all collisions.
They also help keep you in position, away from an
inflating SABIC. To get the best protection from the
SABICs, occupants must wear their seat belts prop-
erly and sit upright with their backs against the seats.
Children must be properly restrained in a child
restraint or booster seat that is appropriate for the
size of the child.
• Side Air Bags need room to inflate. Do not lean
against the door or window. Sit upright in the center
of the seat.
(Continued)
WARNING! (Continued)
•Being too close to the Side Air Bags during deploy-
ment could cause you to be severely injured or
killed.
• Relying on the Side Air Bags alone could lead to
more severe injuries in a collision. The Side Air Bags
work with your seat belt to restrain you properly. In
some collisions, Side Air Bags won’t deploy at all.
Always wear your seat belt even though you have
Side Air Bags.
NOTE: Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Side Impacts
In side impacts, the side impact sensors aid the ORC in
determining the appropriate response to impact events.
The system is calibrated to deploy the Side Air Bags on the
impact side of the vehicle during impacts that require Side
Air Bag occupant protection. In side impacts, the Side Air
Bags deploy independently; a left side impact deploys the
left Side Air Bags only and a right side impact deploys the
right Side Air Bags only.
170 SAFETY

The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during
angled or offset frontal collisions where the front air bags
deploy.
Rollover Events
Side Air Bags are designed to activate in certain rollover
events. The ORC determines whether the deployment of
the Side Air Bags in a particular rollover event is appro-
priate, based on the severity and type of collision. Vehicle
damage by itself is not a good indicator of whether or not
Side Air Bags should have deployed.
The Side Air Bags will not deploy in all rollover events. The
rollover sensing-system determines if a rollover event may
be in progress and whether deployment is appropriate. A
slower-developing event may deploy the seat belt preten-
sioners on both sides of the vehicle. A faster-developing
event may deploy the seat belt pretensioners as well as the
Side Air Bags on both sides of the vehicle. The rollover
sensing-system may also deploy the seat belt pretension-
ers, with or without the Side Air Bags, on both sides of the
vehicle if the vehicle experiences a near rollover event.The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain rollover or side impact events.
