OCCUPANT RESTRAINTS
Some of the most important safety features in your
vehicle are the restraint systems. These include the front
and rear seat belts for the driver and all passengers, front
airbags for both the driver and front passenger, and if
equipped, left and right window bags for the driver and
passengers seated next to a window and a driver inflat-
able knee blocker. If you will be carrying children too
small for adult-size seat belts, your seat belts or the
LATCH feature (refer to the Child Restraint section in this
manual), can be used to hold infant and child restraint
systems.
NOTE:The front airbags have a multi stage inflator
design. This allows the airbag to have different rates of
inflation that are based on collision severity.

WARNING!
Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the lap belt is not long enough when it is worn
low and snug, and in the recommended seating
positions. Remove and store the extender when not
needed.
Driver and Front Passenger Supplemental
Restraint System - Airbag
This vehicle has airbags for both the driver and front
passenger as a supplement to the seat belt restraint
systems. The driver’s front airbag is mounted in the
center of the steering wheel. The passenger’s front airbag
is mounted in the instrument panel, above the glove
compartment. The words SRS AIRBAG are embossed on
the airbag covers.NOTE:The front airbags are certified to the Federal
regulations that allow less forceful deployment in low
speed collisions.
The front airbags have a multi stage inflator design. This
may allow the airbag to have different rates of inflation
that are based on collision severity and occupant size.Front Airbag Components
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

How The Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collision
severity, the front control module determines the
proper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation.
•The ORC may modify the rate of inflation based on the
occupant size provided by the Occupant Classification
Module.
•The ORC will not detect side, roll over, or rear impacts.
•The ORC monitors the readiness of the electronic parts
of the system whenever the ignition switch is in the
START or RUN positions. These include all of the
items listed above except the steering wheel andcolumn, instrument panel and passenger knee bol-
sters. If the key is in the OFF position, in the ACC
position, or not in the ignition, the airbags are not on
and will not inflate.
•Also, the ORC turns on the AIRBAG warn-
ing light and PAD indicator light in the
center of the instrument panel for 6 to 8
seconds for a self-check when the ignition is
first turned on. After the self-check, the AIRBAG
warning light will turn off. The PAD indicator light
will function normally (Refer to “Passenger Airbag
Disable (PAD) Indicator Light” in this section). If the
ORC detects a malfunction in any part of the system, it
turns on the AIRBAG warning light either momen-
tarily or continuously. A single chime will sound if the
light comes on again after initial start up.
56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Ignoring the AIRBAG warning light in your instru-
ment panel could mean you won’t have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC and
impact sensors detects a collision requiring the air-
bags, it signals the inflator units. A large quantity of
nontoxic gas is generated to inflate the front airbags.
Different airbag inflation rates may be possible based
on collision severity and occupant size. The steering
wheel hub trim cover and the upper right side of the
instrument panel separate and fold out of the way asthe airbags inflate to their full size. The airbags fully
inflate in about 50–70 milliseconds. This is about half
of the time it takes to blink your eyes. The airbags then
quickly deflate while helping to restrain the driver and
front passenger.
The driver’s and passenger’s front airbag gas is vented
through the airbag material towards the instrument
panel. In this way the airbags do not interfere with
your control of the vehicle.•TheSide Impact SRS Window Bagsare designed to
activate only in certain side collisions. When the ORC
and the side impact sensors (with side impact option)
detects a collision requiring the window bags to
inflate, it signals the inflators on the crash side of the
vehicle. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
pushes the outside edge of the headliner out of the
way and covers the window. The airbag inflates in

If A Deployment Occurs
The airbag system is designed to deploy the airbags
when the ORC and impact sensors detect a moderate-to-
severe collision, to help restrain the vehicle passengers,
and then immediately deflate.
NOTE:A collision that is not severe enough to need
airbag protection will not activate the system. This does
not mean something is wrong with the airbag system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
•The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
passenger as the airbags 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 airbags deflate you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the nontoxic gas used for airbag
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 instruc-
tions for cleaning.
•It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, the airbags will not be in place to protect you.

21. Tire Pressure Monitoring Telltale Lamp — If
Equipped
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly underinflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the tire tooverheat and can lead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
NOTE:The Tire Pressure Monitoring System (TPMS) is
not a substitute for proper tire maintenance, and it is the
driver ’s responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring System low
tire pressure telltale.
The Tire Pressure Monitoring Telltale Lamp will illumi-
nate in the instrument cluster and an audible chime will
be activated when one or more tire pressures is low. The
Tire Pressure Monitoring Telltale Lamp will flash one and
off for 60 seconds when a system fault is detected. The
flash cycle will repeat every ten minutes or until the fault
conditions is removed and reset.

Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire’s load carrying capacity if you
adhere to the loading conditions, tire size, and cold tire
inflation pressures specified on the “Tire and Loading
Information” placard and in the “Vehicle Loading” sec-
tion of this manual.
NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWR’s) for the front and rear
axles must not be exceeded. For further information on
GAWR’s, vehicle loading, and trailer towing, refer to the
“Vehicle Loading” section of this manual.
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX kg or XXX
lbs.” on the Tire and Loading Information placard. Thecombined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined weight of occu-
pants and cargo should never exceed XXX pounds” on
your vehicle’s placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and pas-
sengers from XXX kilograms or XXX pounds.
4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if “XXX”
amount equals 1400 lbs. and there will be five 150 lb.
passengers in your vehicle, the amount of available cargo
and luggage load capacity is 650 lbs. (since 5 x 150 = 750,
and 1400 – 750 = 650 lbs.)
