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
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
NOTE:Vehicles with front passenger seat deleted will not
be equipped with the Seat Belt Buckle Switch, Seat
Belt Pretensioner, Supplemental Seat Mounted
Side Airbag, and Seat Track Position Sensors for
the front passenger.
All passenger occupants within the vehicle must be
in a seat equipped with a Seat Belt System and
Head Restraint for the safety of the passenger.
If the front passenger and/or rear seats have been
removed do not ride in those areas.
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.
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.

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.
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.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.

204SAFETY
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.

SAFETY205
(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 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.

SERVICING AND MAINTENANCE289
Inflation pressures specified on the placard are
always “cold tire inflation pressure”. Cold tire
inflation pressure is defined as the tire pressure
after the vehicle has not been driven for at least 3
hours, or driven less than 1 mile (1.6 km) after
sitting for a minimum of 3 hours. The cold tire
inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
Check tire pressures more often if subject to a
wide range of outdoor temperatures, as tire
pressures vary with temperature changes.
Tire pressures change by approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature change.
Keep this in mind when checking tire pressure
inside a garage, especially in the Winter.
Example: If garage temperature = 68°F (20°C)
and the outside temperature = 32°F (0°C) then
the cold tire inflation pressure should be increased
by 3 psi (21 kPa), which equals 1 psi (7 kPa) for
every 12°F (7°C) for this outside temperature
condition.
Tire pressure may increase from 2 to 6 psi (13 to
40 kPa) during operation. DO NOT reduce this
normal pressure build up or your tire pressure will
be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits. Where
speed limits or conditions are such that the vehicle
can be driven at high speeds, maintaining correct
tire inflation pressure is very important. Increased
tire pressure and reduced vehicle loading may be
required for high-speed vehicle operation. Refer to
an authorized tire dealer or original equipment
vehicle dealer for recommended safe operating
speeds, loading and cold tire inflation pressures.
Radial Ply Tires
Tire Repair
If your tire becomes damaged, it may be repaired if
it meets the following criteria:
The tire has not been driven on when flat.
The damage is only on the tread section of your
tire (sidewall damage is not repairable).
The puncture is no greater than a ¼ of an inch
(6 mm).
Consult an authorized tire dealer for tire repairs
and additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical
size and service description (Load Index and
Speed Symbol). Replace the tire pressure sensor
as well as it is not designed to be reused.
WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added strain
on your tires could cause them to fail. You could
have a serious collision. Do not drive a vehicle
loaded to the maximum capacity at continuous
speeds above 75 mph (120 km/h).
WARNING!

Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause a collision.
Always use radial ply tires in sets of four. Never
combine them with other types of tires.

290SERVICING AND MAINTENANCE
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after a
rapid loss of inflation pressure. This rapid loss of
inflation is referred to as the Run Flat mode. A Run
Flat mode occurs when the tire inflation pressure is
of/or below 14 psi (96 kPa). Once a Run Flat tire
reaches the Run Flat mode it has limited driving
capabilities and needs to be replaced immediately.
A Run Flat tire is not repairable. When a Run Flat
tire is changed after driving with underinflated tire
condition, please replace the TPMS sensor as it is
not designed to be reused when driven under Run
Flat mode 14 psi (96 kPa) condition.
NOTE:TPMS Sensor must be replaced after driving the
vehicle on a flat tire condition.
It is not recommended driving a vehicle loaded at
full capacity or to tow a trailer while a tire is in the
Run Flat mode.
See the Tire Pressure Monitoring System section
for more information.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions,
do not spin your vehicle's wheels above 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping.
For further information Úpage 243.
Tread Wear Indicators
Tread wear indicators are in the original equipment
tires to help you in determining when your tires
should be replaced.

Tire Tread
These indicators are molded into the bottom of the
tread grooves. They will appear as bands when the
tread depth becomes a 1/16 of an inch (1.6 mm).
When the tread is worn to the tread wear
indicators, the tire should be replaced.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
Driving style.
Tire pressure - Improper cold tire inflation pres
-
sures can cause uneven wear patterns to
develop across the tire tread. These abnormal
wear patterns will reduce tread life, resulting in
the need for earlier tire replacement.
Distance driven.
Performance tires, tires with a speed rating of V
or higher, and Summer tires typically have a
reduced tread life. Rotation of these tires per
the vehicle scheduled maintenance is highly
recommended.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin your
vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when
you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.
1 — Worn Tire
2 — New Tire
WARNING!
Tires and the spare tire should be replaced after
six years, regardless of the remaining tread.
Failure to follow this warning can result in
sudden tire failure. You could lose control and
have a collision resulting in serious injury or
death.
