248SAFETY
NOTE:
The TPMS is not intended to replace normal tire
care and maintenance, or to provide warning of
a tire failure or condition.
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi -
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate tire pressure gauge, even if underinflation
has not reached the level to trigger illumination
of the TPMS Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
Premium System
The Tire Pressure Monitoring 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 System sensors
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster
Tire Pressure Monitoring System Warning Light
SERVICE TPMS WARNING
When a system fault is detected, the Tire Pressure
Monitoring System (TPMS) Warning 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 instrument cluster will display a
"SERVICE TPM 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.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may
result when using replacement equipment
that is not of the same size, type, and/or style.
The TPMS sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
OEM wheels to ensure proper TPMS feature
operation.
Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.

21_RUP_OM_EN_USC_t.book Page 248

SAFETY249
If the ignition is cycled, this sequence will repeat,
providing the system fault still exists. If the system
fault no longer exists, the TPMS Warning Light will
no longer flash, and the “SERVICE TPM 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:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors
Installing some form of aftermarket window
tinting that affects radio wave signals
Lots of snow or ice around the wheels or wheel
housings
Using tire chains on the vehicle
Using wheels/tires not equipped with TPMS
sensors
Vehicles With Compact Spare — If Equipped

1. The compact spare tire does not have a Tire Pressure Monitoring System sensor.
Therefore, the TPMS will not monitor 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 warning limit, upon the next
ignition cycle, the TPMS Warning Light will
remain on and a chime will sound. In addition,
the graphic in the instrument cluster will still
display a different color pressure value. 3. After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the TPMS Warning
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 five seconds and then
display dashes (--) in place of the pressure
value.
4. For each subsequent ignition cycle, a chime will sound, the TPMS Warning Light will flash
on and off for 75 seconds and then remain on
solid, and the instrument cluster will display a
“SERVICE TPM SYSTEM” message 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 automat -
ically. In addition, the TPMS Warning Light will
turn off and the graphic in the instrument
cluster 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.
TIRE PRESSURE MONITORING SYSTEM LOW
PRESSURE WARNINGS
The TPMS Warning Light will illuminate in
the instrument cluster and a chime will
sound when tire pressure is low in one or
more of the four active road tires. In
addition, the instrument cluster will display an
"Inflate to XX" message and a graphic showing the
pressure values of each tire with the low tire
pressure values in a different color.

Tire Pressure Monitoring System

Should this occur, you should stop as soon as
possible and inflate the tires with low pressure
(those in a different color in the instrument cluster
graphic) to the vehicle’s recommended cold
placard pressure value as shown in the
"Inflate to XX" message.

21_RUP_OM_EN_USC_t.book Page 249

250SAFETY
Once the system receives the updated tire
pressures, the system will automatically update,
the pressure values in the graphic display in the
instrument cluster will return to their original color,
and the TPMS Warning Light will turn 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.
TPMS DEACTIVATION — IF EQUIPPED
The Tire Pressure Monitoring System (TPMS) can
be deactivated if replacing all four wheel and tire
assemblies (road tires) with wheel and tire
assemblies that do not have TPMS sensors, such
as when installing winter wheel and tire
assemblies on your vehicle.
To deactivate the TPMS, first, replace all four wheel
and tire assemblies (road tires) with tires not
equipped with Tire Pressure Monitoring System
(TPMS) sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the TPMS Warning Light will flash on
and off for 75 seconds and then remain on. The
instrument cluster will display the “SERVICE TPM
SYSTEM” message and then display dashes (--) in
place of the pressure values. Beginning with the next ignition cycle, the TPMS
will no longer chime or display the “SERVICE TPM
SYSTEM” message in the instrument cluster but
dashes (--) will remain in place of the pressure
values.
To reactivate the TPMS, replace all four wheel and
tire assemblies (road tires) with tires equipped with
TPMS sensors. Then, drive the vehicle for up to
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the TPMS Warning Light will flash on
and off for 75 seconds and then turn off. The
instrument cluster will display the “SERVICE TPM
SYSTEM” message and then display pressure
values in place of the dashes. On the next ignition
cycle the "SERVICE TPM SYSTEM" message will no
longer be displayed as long as no system fault
exists.
OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your
vehicle are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air Bags
Child Restraints
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 an authorized dealer.
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 the rear seat of a
vehicle with a rear seat.

2. A child who is not big enough to wear the vehicle seat belt properly must be secured in
the appropriate child restraint or
belt-positioning booster seat in a rear seating
position Ú page 275.

21_RUP_OM_EN_USC_t.book Page 250

SAFETY261
SUPPLEMENTAL RESTRAINT SYSTEMS
(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 an authorized dealer.
The air bag system must be ready to protect you in
a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and
interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air Bag
System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Occupant Classification System
Air Bag Warning Light
The Occupant Restraint Controller (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 bag system 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 in the ON/RUN position. After the self-check,
the Air Bag Warning Light will turn off. If the ORC
detects a malfunction 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 malfunction 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 igni
-
tion switch is first in 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 intermit -
tently or remains on while driving.

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 determined 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 Advanced 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.
This vehicle is equipped with a right front
passenger Occupant Classification System (OCS)
that is designed to provide Passenger Advanced
Front Air Bag output appropriate to the occupant’s
seated weight input, as determined by the OCS.
WARNING!
Being too close to the steering wheel or instru
-
ment panel during front air bag deployment
could cause serious injury, including death. Air
bags need room to inflate. Sit back, comfort -
ably extending your arms to reach the steering
wheel or instrument panel.
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.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.
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 collisions, air bags won’t
deploy at all. Always wear your seat belts even
though you have air bags.6

21_RUP_OM_EN_USC_t.book Page 263

264SAFETY
Front Air Bag Operation
Front Air Bags are designed to provide additional
protection 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 substantial
vehicle damage — for example, some pole
collisions, 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 Occupant Restraint Controller (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
passenger 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.
Occupant Classification System (OCS) —
Front Passenger Seat
The Occupant Classification System (OCS) is part
of a Federally regulated safety system for this
vehicle. It is designed to provide Passenger
Advanced Front Air Bag output appropriate to the
occupant’s seated weight, as determined by the
OCS.The Occupant Classification System (OCS) consists
of the following:
Occupant Restraint Controller (ORC)
Occupant Classification Module (OCM) and
Sensor 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 located 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 passenger’s
most probable classification. The OCM
communicates 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 properly
wearing the seat belt.

Supplemental Side Air Bag Inflatable Curtains
(SABICs)
This vehicle is equipped with Supplemental Side
Air Bag Inflatable Curtains (SABICs).
Supplemental Side Air Bag Inflatable Curtains
(SABICs) are located above the side windows. The
trim covering the SABICs is labeled “SRS AIRBAG”
or “AIRBAG.”

Supplemental Side Air Bag Inflatable Curtain (SABIC) Label Location

SABICs may help reduce the risk of head and other
injuries to front and rear seat outboard occupants
in certain side impacts, in addition to the injury
reduction potential provided by the seat belts and
body structure. The SABIC deploys downward, covering the side
windows. An inflating SABIC pushes the outside
edge of the headliner out of the way and covers the
window. The SABICs inflate with enough force to
injure occupants if they are not belted and seated
properly, or if items are positioned in the area
where the SABICs inflate. Children are at an even
greater risk of injury from a deploying air bag.
The SABICs may help reduce the risk of partial or
complete ejection of vehicle occupants through
side windows in certain side impact events.
Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the
deployment of the Side Air Bags in a particular
impact event is appropriate, based on the severity
and type of collision. 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. 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 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.
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!
Do not mount equipment, or stack luggage or
other cargo up high enough to block the
deployment of the SABICs. The trim covering
above the side windows where the SABIC and
its deployment path are located should
remain free from any obstructions.
In order for the SABICs to work as intended, do
not install any accessory items in your vehicle
which could alter the roof. Do not add an after
-
market sunroof to your vehicle. Do not add
roof racks that require permanent attach -
ments (bolts or screws) for installation on the
vehicle roof. Do not drill into the roof of the
vehicle for any reason.

SAFETY271
(Continued)
NOTE:Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Rollover Events
Side Air Bags and seat belt pretensioners are
designed to activate in certain rollover events. The
Occupant Restraint Controller (ORC) determines
whether deployment in a particular rollover event
is appropriate, based on the severity and type of
collision. Vehicle damage by itself is not a good
indicator of whether or not Side Air Bags and seat
belt pretensioners should have deployed.
The Side Air Bags and seat belt pretensioners 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. In the event the vehicle experiences a
rollover or near rollover event, and deployment is
appropriate, the rollover sensing system will deploy
the side air bags and seat belt pretensioners on
both sides of the vehicle. 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.

WARNING!
Occupants, including children, who are up
against or very close to Side Air Bags 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 appro -
priate) are necessary for your protection in all
collisions. They also help keep you in position,
away from an inflating Side Air Bag. To get the
best protection from the Side Air Bags, occu -
pants must wear their seat belts properly 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.
WARNING!
Side Air Bags need room to inflate. Do not lean
against the door or window. Sit upright in the
center of the seat.
Being too close to the Side Air Bags during
deployment 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.
