Curtain air bags
Curtain air bags are located along
both sides of the roof rails above the
front and rear doors.They are designed to help protect the
heads of the front seat occupants
and the rear outboard seat occupants
in certain side impact collisions.
The curtain air bags are designed to
deploy only during certain side
impact collisions, depending on the
crash severity, angle, speed and
impact.
The side and curtain air bags on
both sides of the vehicle may deploy
if a rollover or possible rollover is
detected.
The curtain air bags are not designed
to deploy in all side impact or rollover
situations.
To reduce the risk of serious
injury or death from an inflating
curtain air bags, take the follow-
ing precautions:All seat occupants must wear
seat belts at all times to help
keep occupants positioned
properly. (Continued)
(Continued)
Properly secure child restraints
as far away from the door as
possible.
Do not place any objects over
the air bag. Also, do not attach
any objects around the area the
air bag inflates such as the
door, side door glass, front and
rear pillar, roof side rail.
Do not hang other objects
except clothes, especially
hard or breakable objects. In
an accident, it may cause vehi-
cle damage or personal injury.
Do not allow passengers to
lean their heads or bodies
onto doors, put their arms on
the doors, stretch their arms
out of the window, or place
objects between the doors
and seats.
Do not open or repair the side
curtain air bags.

To help provide protection, the airbags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which to
inflate the air bag between the
occupant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries and is thus a
necessary part of air bag design.
However, the rapid air bag inflation
can also cause injuries which can
include facial abrasions, bruises and
broken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
There are even circumstances under which contact with the air
bag can cause fatal injuries, espe-
cially if the occupant is positioned
excessively close to the air bag.
You can take steps to reduce the risk
of being injured by an inflating air
bag. The greatest risk is sitting too
close to the air bag. An air bag needs
about 10 inches (25 cm) of space to
inflate. NHTSA recommends that
drivers allow at least 10 inches
(25 cm) between the center of the
steering wheel and the chest. When the SRSCM detects a suffi-
ciently severe impact to the front of
the vehicle, it will automatically
deploy the front air bags.

dren under age 13 in the rear
seats of the vehicle.
Adjust the front passenger's

trol of the vehicle.
Hold the steering wheel with
hands at the 9 o'clock and 3

Never place anything or any-
one between the air bag and
the seat occupant.
Do not allow the front passen-
ger to place their feet or legs

Safety system of your vehicle
Occupant Classification
System (OCS)
Your vehicle is equipped with an
Occupant Classification System
(OCS) in the front passenger's seat.
Main components of theOccupant Classification System
A detection device located within
the front passenger seat cushion.
Electronic system to determine whether the passenger air bag
systems should be activated or
deactivated.
An indicator light located on the instrument panel which illuminates
the words "PASSENGER AIR BAG
OFF" indicating the front passen-
ger air bag system is deactivated.
The instrument panel air bag indi- cator light is interconnected with
the OCS.
The OCS is designed to help detect
the presence of a properly-seated
front passenger and determine if the
passenger's front air bag should be
enabled (may inflate) or not.
The purpose is to help reduce the
risk of injury or death from an inflat-
ing air bag to certain front passenger
seat occupants, such as children, by
requiring the air bag to be automati-
cally turned OFF. For example, if a child restraint of the
type specified in the regulations is on
the seat, the occupant classification
sensor can detect it and cause the
air bag to turn OFF.
Front passenger seat adult occu-
pants who are properly seated and
wearing the seat belt properly,
should not cause the passenger air
bag to be automatically turned OFF.
For small adults it may be turned
OFF, however, if the occupant does
not sit in the seat properly (for exam-
ple, by not sitting upright, by sitting
on the edge of the seat, or by other-
wise being out of position), this could
cause the sensor to turn the air bag
OFF.
You will find the "PASSENGER AIR
BAG OFF" indicator on the center
facia panel. This system detects the
conditions 1-4 in the following table
and activates or deactivates the front
passenger air bag based on these
conditions.

Always be sure that you and all vehi-
cle occupants are seated properly
and wearing the seat belt properly for
the most effective protection by the
air bag and the seat belt.
The OCS may not function properly if
the passenger takes actions which
can affect the classification system.
These include:
Failing to sit in an upright position.
Leaning against the door or centerconsole.
Sitting towards the sides of the front of the seat.
Putting their legs on the dashboard or resting them on other locations
which reduce the passenger
weight on the front seat.
Wearing the seat belt improperly.
Reclining the seatback.
Wearing a thick cloth like ski wear or hip protection wear.
Putting an additional thick cushion on the seat.
Putting electrical devices (e.g. notebook, satellite radio) on the
seat with inverter charging.Condition and operation in the front passenger Occupant Classification System

Safety system of your vehicle
The "PASSENGER AIR BAG OFF"
indicator illuminates for approxi-
mately 4 seconds after the ignition
switch is in the ON position or
after the engine is started. If the
front passenger seat is occupied,
the OCS will then classify the front
passenger after several more sec-
onds.
Do Not Install a Child Restraint in the Front Passenger's Seat
Even though your vehicle is
equipped with the OCS, never install
a child restraint in the front passen-
ger's seat. An inflating air bag can
forcefully strike a child or child
restraint resulting in serious or fatal
injury.
NOTICE
NEVER place a rear-facing or
front-facing child restraint in
the front passenger's seat of
the vehicle.
An inflating frontal air bag
could forcefully strike a child
resulting in serious injury or
death.
Always properly restrain chil-
dren in an appropriate child
restraint in the rear seat of the
vehicle.
