SEATS
Seats are a part of the Occupant Restraint
System of the vehicle.
WARNING!
It is dangerous to ride in a cargo area,
inside or outside of a vehicle. In a colli
-
sion, people riding in these areas are
more likely to be seriously injured or
killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts. In a collision,
people riding in these areas are more
likely to be seriously injured or killed.
Be sure everyone in your vehicle is in a
seat and using a seat belt properly.

Seat Belts And Pregnant Women
Seat Belts And Pregnant Women
Seat belts must be worn by all occupants
including pregnant women: the risk of injury
in the event of an accident is reduced for the
mother and the unborn child if they are
wearing a seat belt.

Position the lap belt snug and low below the
abdomen and across the strong bones of the hips.
Place the shoulder belt across the chest and away
from the neck. Never place the shoulder belt
behind the back or under the arm.

Seat Belt Pretensioner

The front outboard seat belt system is equipped
with pretensioning devices that are designed to
remove slack from the seat belt in the event of
a collision. These devices may improve the performance of the seat belt by removing slack
from the seat belt early in a collision. Preten
-
sioners work for all size occupants, including
those in child restraints.

NOTE:
These devices are not a substitute for proper
seat belt placement by the occupant. The
seat belt still must be worn snugly and posi -
tioned properly.
The pretensioners are triggered by the Occu -
pant Restraint Controller (ORC). Like the air
bags, the pretensioners are single use items.
A deployed pretensioner or a deployed air
bag must be replaced immediately.
Energy Management Feature

The front outboard seat belt system is equipped
with an Energy Management feature that may
help further reduce the risk of injury in the event
of a collision. The seat belt system has a retractor
assembly that is designed to release webbing in a
controlled manner.

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:

NOTE:
Air bag covers may not be obvious in the inte-

deployment.

NOTE:
The Occupant Restraint Controller (ORC)
monitors the internal circuits and intercon -
necting wiring associated with electrical Air
Bag System Components listed below:

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 fric-
tion rope burns or those you might get
sliding along a carpet or gymnasium floor.
They are not caused by contact with chem -
icals. 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.
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 -
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.

(Continued)
NOTE:
After an accident, remember to cycle the
ignition to the STOP (OFF/LOCK) position
and remove the key from the ignition switch
to avoid draining the battery. Carefully check
the vehicle for fuel leaks in the engine
compartment and on the ground near the
engine compartment and fuel tank before
resetting the system and starting the engine.
If there are no fuel leaks or damage to the
vehicle electrical devices (e.g. headlights)
after an accident, reset the system by
following the procedure described below. If
you have any doubt, contact an authorized
dealer.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident
Response System functions after an event,
the ignition switch must be changed from
ignition START or ON/RUN to ignition OFF.
Carefully check the vehicle for fuel leaks in
the engine compartment and on the ground
near the engine compartment and fuel tank
before resetting the system and starting the
engine.
Maintaining Your Air Bag System
WARNING!

Modifications to any part of the air bag
system could cause it to fail when you need
it. You could be injured if the air bag
system is not there to protect you. Do not
modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
cover or the upper passenger side of the
instrument panel. Do not modify the front
bumper, vehicle body structure, or add
aftermarket side steps or running boards.

It is dangerous to try to repair any part of
the air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.
Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function properly
if modifications are made. Take your
vehicle to an authorized dealer for any air
bag system service. If your seat,
including your trim cover and cushion,
needs to be serviced in any way
(including removal or loosening/
tightening of seat attachment bolts),
take the vehicle to an authorized dealer.
Only manufacturer approved seat
accessories may be used. If it is
necessary to modify the air bag system
for persons with disabilities, contact an
authorized dealer.
