TPMS Temporarily Disabled:
TPMS Check Message
When a system fault is detected, the Tire Pres-
sure 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 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 Moni
-
toring System 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 pres -
sure 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 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 igni
-
tion 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.

The TPMS should not be used as a tire pres -
sure gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire will
cause 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 responsi -
bility to maintain correct tire pressure using
an accurate tire pressure gauge, even if
underinflation has not reached the level to
trigger illumination of the Tire Pressure
Monitoring System Warning Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor the
actual tire pressure in the tire

How To Disengage The Automatic Locking
Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disengage
the Automatic Locking Mode and activate the
vehicle sensitive (emergency) locking mode.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
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 posi -
tion, 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 illu -
minate 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 mainte - WARNING!
The seat belt assembly must be replaced
if the switchable Automatic Locking
Retractor (ALR) feature or any other seat
belt function is not working properly when
checked according to the procedures in
the Service Manual.
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 harness for
restraining the child.

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 roll -
over 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
Supplemental 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, pretensioners, and front air bags.
Driver Knee Air Bag
Front Passenger Knee Air Bag
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.

The Side Air Bags and seat belt pretensioners
will not deploy in all rollover events. The roll-
over sensing system determines if a rollover
event may be in progress and whether deploy -
ment 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.

NOTE:

The Occupant Restraint Controller (ORC) moni -
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

Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
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 irri -
tate 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 manufac -
turer’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.
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.
