TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The vehicle is equipped with a TPMS that sends
the inflation pressure information of each tire to
the control unit, and will signal the driver in the
event of insufficient tire pressure. The 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.
Tire pressure will vary with temperature by
approximately 1 psi (7 kPa) for every 12°F
(6.5°C). This means that when the outside
temperature decreases, the tire pressure will
also decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is
defined as the tire pressure after the vehicle has
not been driven for at least three hours, or driven
less than 1 mile (1.6 km) after a three hour
period. The cold tire inflation pressure must not
exceed the maximum inflation pressure molded
into the tire sidewall. The tire pressure will also
increase as the vehicle is driven. This is normal,
and there should be no adjustment for this
increased pressure. See

Ú
page 206 for
information on how to properly inflate the
vehicle’s tires.
The TPMS will signal the driver if pressure falls
below the warning limit for any reason, including
the effects of low temperature and normal loss of
pressure from the tire.
The TPMS will stop indicating insufficient tire
pressure when pressure is equal to or greater
than the prescribed cold inflation level.
Therefore, if insufficient tire pressure is indicated
by the ( ) warning light displaying in the
instrument cluster, increase the inflation
pressure up to the prescribed cold inflation value. The system will automatically update, and the
Tire Pressure Monitoring System Warning Light
will turn off once the system receives the updated
tire pressures. 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.

NOTE:
The TPMS cannot indicate sudden tire pressure
drops (e.g. if a tire bursts). In this case, proceed
with caution and avoid abrupt steering.
Operating Example
For example, your vehicle may have a
recommended cold (parked for more than three
hours) placard pressure of 33 psi (227 kPa). If
the ambient temperature is 68°F (20°C), and the
measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn
on the Tire Pressure Monitoring System Warning
Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi
(193 kPa), but the Tire Pressure Monitoring
System Warning Light will still be on. In this
situation, the Tire Pressure Monitoring System
Warning Light will turn off only after the tires are
inflated to the vehicle’s recommended cold
placard pressure value.
WARNING!
The system has not been designed to
prevent impacts and cannot detect possible
conditions leading to an accident in
advance. Failure to take into account this
warning may lead to serious or fatal injuries.
The system may activate, assessing the
trajectory of the vehicle, for the presence of
reflecting metal objects different from other
vehicles, such as safety barriers, road signs,
barriers before parking lots, tollgates, level
crossings, gates, railways, objects near road
constructions sites or higher than the vehicle
(e.g. a fly-over). In the same way, the system
may intervene inside multi-story parking lots
or tunnels, or due to a glare on the road
surface. These possible activations are a
consequence of the real driving scenario
coverage by the system and must not be
regarded as faults.
The system has been designed for road use
only. If the vehicle is driven on a track, the
system must be deactivated to avoid
unnecessary warnings. Automatic deacti
-
vation is signaled by the dedicated warning
light/symbol switching on in the instrument
panel

Insufficient Tire Pressure Indication
If an insufficient pressure value is detected on
one or more tires, the Tire Pressure Monitoring
System Warning Light in the instrument cluster
will display alongside the dedicated messages,
the system will highlight the tire or tires with
insufficient pressure graphically, and an acoustic
signal will be emitted.In this case, stop the vehicle, check the inflation
pressure of each tire, and inflate the necessary
tire or tires to the correct cold inflation pressure
value, shown on the display or in the dedicated
TPMS menu.
TPMS Temporarily Disabled:
TPMS Check Message
When a system fault is detected, the Tire
Pressure Monitoring System Warning 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,
provided that the system fault still exists. The Tire
Pressure Monitoring System Warning Light will
turn off when the fault condition no longer exists.
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.
Packed snow or ice around the wheels or
wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
After the punctured tire has been repaired with
the original tire sealant contained in the tire kit,
the previous condition must be restored so that
the Tire Pressure Monitoring System Warning
Light is off during normal driving.
TPMS Deactivation
The TPMS can be deactivated by 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 sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the Tire Pressure Monitoring System
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 switch cycle, the
TPMS will no longer chime or display the
“SERVICE TPM SYSTEM” message in the
instrument cluster. Instead, 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 Tire
Pressure Monitoring System 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 switch cycle the "SERVICE TPM
SYSTEM" message will no longer be displayed, as
long as no system fault exists.

NOTE:

The TPMS is not intended to replace normal
tire care and maintenance, or to provide
warning of a tire failure or condition.
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 Original Equipment
Manufacturer (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.

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
ignition 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.

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 protection. Have an authorized
dealer service the air bag system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light
is detected, which could affect the
Supplemental Restraint System (SRS),
the Redundant Air Bag Warning Light
will illuminate on the instrument panel. The
Redundant Air Bag Warning Light will stay on until
the fault is cleared. In addition, a single chime will
sound to alert you that the Redundant Air Bag
Warning Light has come on and a fault has been
detected. If the Redundant Air Bag Warning Light
comes on intermittently or remains on while
driving have an authorized dealer service the
vehicle immediately.

Front Air Bags
This vehicle has front air bags and lap/shoulder
belts for both the driver and front passenger. The
front air bags are a supplement to the seat belt
restraint systems. The driver front air bag is
mounted in the center of the steering wheel. The
passenger front air bag is mounted in the
instrument panel, above the glove compartment.
The words “SRS AIRBAG” or “AIRBAG” are
embossed on the air bag covers.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bag system 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

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.1 — Driver And Passenger Front Air Bags
2 — Driver And Passenger Knee Impact
Bolsters/Supplemental Knee Air Bags
WARNING!
Being too close to the steering wheel or
instrument panel during front air bag
deployment could cause serious injury,
including death. Air bags need room to
inflate. Sit back, comfortably 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!

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.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees
of the driver and front passenger, and position
the front occupants for improved interaction with
the front air bags.
Supplemental Driver And Front
Passenger Knee Air Bags
This vehicle is equipped with a Supplemental
Driver Knee Air Bag mounted in the instrument
panel below the steering column and a Supple
-
mental Passenger Knee Air Bag mounted in the
instrument panel below the glove compartment.
The Supplemental Knee Air Bags provide
enhanced protection during a frontal impact by
working together with the seat belts, preten -
sioners, and front air bags.
Driver Knee Air Bag
Front Passenger Knee Air Bag
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.
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.

(Continued)
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.

NOTE:
Air bag covers may not be obvious in the interior
trim, but they will open during air bag deploy
-
ment. 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 preten
-
sioners 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.
Air Bag System Components

NOTE:

tors the internal circuits and interconnecting
wiring associated with electrical Air Bag System
Components listed below:
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
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
appropriate) 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, occupants 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.

If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.

NOTE:
Front and/or side air bags will not deploy in all
collisions. This does not mean something is
wrong with the air bag system.
If you do have a collision which deploys the air
bags, any or all of the following may occur:
The air bag material may sometimes cause
abrasions and/or skin reddening to the
occupants as the air bags deploy and unfold.
The abrasions are similar to friction rope burns
or those you might get sliding along a carpet or
gymnasium floor. They are not caused by
contact with chemicals. They are not
permanent and normally heal quickly.
However, if you haven’t healed significantly
within a few days, or if you have any blistering,
see your doctor immediately.

As the air bags deflate, you may see some
smoke-like particles. The particles are a normal
by-product of the process that generates the
non-toxic gas used for air bag inflation. These
airborne particles may irritate the skin, eyes,
nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues, see your doctor. If these particles
settle on your clothing, follow the garment
manufacturer’s instructions for cleaning.

Do not drive your vehicle after the air bags have
deployed. If you are involved in another collision,
the air bags will not be in place to protect you.

NOTE:

Air bag covers may not be obvious in the
interior trim, but they will open during air bag
deployment.
After any collision, the vehicle should be taken
to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication
network remains intact, and the power remains
intact, depending on the nature of the event, the
Occupant Restraint Controller (ORC) will
determine whether to have the Enhanced
Accident Response System perform the following
functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor (if
equipped)
Flash hazard lights as long as the battery has
power
Turn on the interior lights, which remain on as
long as the battery has power or for
15 minutes from the intervention of the
Enhanced Accident Response System
Unlock the power door locks
Your vehicle may also be designed to perform any
of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC
Circulation Door
Cut off battery power to the: • Engine
• Electric Motor (if equipped)
• Electric power steering
• Brake booster
• Electric park brake
• Automatic transmission gear selector
• Horn
• Front wiper
• Headlamp washer pump (if equipped)

NOTE:
After an accident, remember to cycle the ignition
to the OFF position and remove the key from the
ignition switch to avoid draining the battery. Care -
fully check the vehicle for fuel leaks in the engine
compartment and on the ground near the engine
compartment and fuel tank before resetting the
system and starting the engine. If there are no
fuel leaks or damage to the vehicle electrical
devices (e.g. headlights) after an accident, reset
the system by following the procedure described
below. If you have any doubt, contact an autho -
rized dealer.
WARNING!
Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have
the air bags, seat belt pretensioners, and the
seat belt retractor assemblies replaced by an
authorized dealer immediately. Also, have the
Occupant Restraint Controller System serviced
as well.
