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.
System Operation
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 compo-
nents:
• Receiver module
• Four tire pressure monitoring sensors
• Various tire pressure monitoring system
messages, which display in the instrument
cluster
• Tire pressure monitoring telltale light
Tire Pressure Monitoring Low Pressure Warn-
ings
The TPMS Warning Light will illumi-
nate 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 a "Tire Low" message for a minimum
of five seconds and a graphic showing the
pressure values of each tire with the low tire
pressure values in a different color.
Tire Pressure Monitoring Display
SAFETY
96

Should this occur, you should stop as soon as
possible and inflate the tires with low pres-
sure (those in a different color in the instru-
ment cluster graphic) to the vehicle’s recom-
mended cold placard pressure value. Once
the system receives the updated tire pres-
sures, 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.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 plac-
ard pressure in order to turn the TPMS Warn-
ing Light off. The vehicle may need to be
driven for up to 10 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 TPMS
Warning Light will flash on and off for 75 sec-
onds and then remain on solid. The system
fault will also sound a chime. In addition, the
instrument cluster will display a "SERVICE
TIRE PRESSURE 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, providing the system fault still exists.
If the system fault no longer exists, the TPMS
Warning Light will no longer flash, and the
“SERVICE TIRE PRESSURE SYSTEM” mes-sage 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 driv-
ing 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 or Non-Matching
Full Size Spare
1. The compact spare tire or non-matching
full size does not have a tire pressure
monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the com-
pact spare tire.
2. If you install the compact or non-
matching full size spare tire in place of a
road tire that has a pressure below the
low-pressure warning limit, upon the next
Tire Pressure Monitoring Low Pressure
Warning
97

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 10 min-
utes 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 dis-
play a “Service Tire Pressure 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 instru-
ment cluster will display a “SERVICE
TIRE PRESSURE 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 or non-
matching full size, the TPMS will update
automatically. In addition, the TPMSWarning 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 10 minutes
above 15 mph (24 km/h) in order for the
TPMS to receive this information.
Vehicles With a Full Size Matching Spare
1. If your vehicle is equipped with a match-
ing full-size spare wheel and tire assem-
bly, it has a tire pressure monitoring sen-
sor, and can be monitored by the Tire
Pressure Monitoring System (TPMS)
when swapped with a low pressure road
tire.
2. In the event that the matching full-size
spare tire is swapped with a low pressure
road tire, the next ignition switch cycle
will still show the TPMS Warning Light to
be on, a chime to sound, and the graphic
display will still show the low tire pressure
value in a different color.3. Driving the vehicle for up to 10 minutes
above 15 mph (24 km/h) will turn off the
TPMS Warning Light as long as none of
road tires are below the low pressure
warning threshold.
TPMS Deactivation — If Equipped
The 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 Moni-
toring (TPM) Sensors. Then, drive the vehicle
for 10 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 dis-
play the “SERVICE TIRE PRESSURE SYS-
TEM” message and then display dashes (--)
in place of the pressure values.
SAFETY
98

Beginning with the next ignition cycle, the
TPMS will no longer chime or display the
“SERVICE TIRE PRESSURE SYSTEM” mes-
sage 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 10 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 TIRE
PRESSURE SYSTEM” message and then dis-
play pressure values in place of the dashes.
On the next ignition cycle the "SERVICE TIRE
PRESSURE 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 Features
• 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 (Refer to “Child
Restraints” in this section for further in-
formation) must be secured in the appro-
priate child restraint or belt-positioning
booster seat in a rear seating position.
3. If a child from 2 to 12 years old (not in a
rear-facing child restraint) must ride in
the front passenger seat, move the seat asWarning Label On Front Passenger Sun

How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull down-
ward until the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat
belt retracts, you will hear a clicking
sound. This indicates the seat belt is now
in the Automatic Locking Mode.
How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disen-
gage the Automatic Locking Mode and acti-
vate the vehicle sensitive (emergency) lock-
ing mode.
WARNING!
• The seat belt assembly must be replaced
if the switchable Automatic Locking Re-
tractor (ALR) feature or any other seat
belt function is not working properly
when checked according to the proce-
dures in the Service Manual.
WARNING!
• Failure to replace the seat belt assembly
could increase the risk of injury in colli-
sions.
• 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 har-
ness for restraining the child.
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 cir-
cuits and interconnecting wiring associated
with the electrical Air Bag System Compo-
nents. 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
• Front and Side Impact Sensors
• Seat Belt Pretensioners
Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system when-
ever 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.
SAFETY

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 compart-
ment. The words “SRS AIRBAG” or “AIRBAG”
are embossed on the air bag covers.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 use a rearward facing child re-
straint on a seat protected by an ACTIVE
AIRBAG in front of it, DEATH or SERI-
OUS INJURY to the CHILD can occur.
• It is advisable to always carry children in
a child restraint system on the rear seat,
which is the most protected position in
the event of a collision.
• Should it be necessary to carry a child on
the passenger side front seat in a rear-
facing child restraint system, the pas-
senger side front airbag must be deacti-
vated. Always make sure the airbag
deactivation indicator light is illumi-
nated when using a child restraint sys-
tem. The passenger seat must also be
positioned backward as far as possible
WARNING!
to avoid the child restraint system from
coming into contact with the dashboard.
• 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.
Driver And Passenger Front Air Bag Features
The front air bag system is designed to inflate
based on the severity and type of collision as
determined by the Occupant Restraint Con-
troller (ORC), which may receive information
from the front impact sensors (if equipped) or
other system components. The driver front air
bag system has a single stage air bag. The
passenger front air bag system has a multi-
stage front air bag. The first stage inflator is
triggered immediately during an impact that
requires air bag deployment. For the multi-
stage air bag, 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 passenger multistage Front 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.
Front Air Bag Operation
Front Air Bags are designed to provide addi-
tional 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 de-
celeration over time, vehicle speed and dam-
age by themselves are not good indicators of
whether or not an air bag should have de-
ployed.
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 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.
Passenger Air Bag Disable Feature — If
Equipped
This system allows the driver to DISABLE
(OFF) the Passenger Advanced Front Air Bag
if a child restraintmustbe installed in the
front seat. Only DISABLE (OFF) the Passen-
ger Advanced Front Air Bag if it is absolutely

child restraint.
• Seat belts (and child restraints where
appropriate) are necessary for your pro-
tection in all collisions. They also help
keep you in position, away from an in-
flating 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 colli-
WARNING!
sion. 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.
Air Bag System Components
NOTE:
The Occupant Restraint Controller (ORC)
monitors the internal circuits and intercon-
necting 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
• Driver and Front Passenger Air Bags• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
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 oc-
cupants 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 blis-
tering, see your doctor immediately.
