Front passenger sensing system

For airbags to do their job they must inflate with great force, and this
force can pose a potentially deadly risk to occupants that are very close
to the airbag when it begins to inflate. For some occupants, like infants
in rear-facing child seats, this occurs because they are initially sitting
very close to the airbag. For other occupants, this occurs when the
occupant is not properly restrained by safety belts or child safety seats
and they move forward during pre-crash braking. The most effective way
to reduce the risk of unnecessary injuries is to make sure all occupants
are properly restrained. Accident statistics suggest that children are
much safer when properly restrained in the rear seating positions than in
the front.

WARNING: Air bags can kill or injure a child in a child seat.
NEVER place a rear-facing child seat in front of an active air

bag. If you must use a forward-facing child seat in the front seat, move
the seat all the way back.

WARNING: When possible, all children 12 years old and under
should be properly restrained in a rear seating position.

The front passenger sensing system can automatically turn off the front
passenger airbag and passenger seat-mounted side airbag. The system is
designed to help protect small (child size) occupants from frontal airbag
deployments when they are seated or restrained in the front passenger
seat contrary to proper child-seating or restraint usage
recommendations. Even with this technology, parents are STRONGLY
encouraged to always properly restrain children in the rear seat. The
sensor also turns off the passenger front airbag when the passenger seat
is empty. The sensor turns off the passenger seat-mounted side airbag
when the seat is empty and the safety belt is unbuckled or buckled.

When the front passenger seat is occupied and the sensing system has
turned off the passenger’s frontal airbag, the “pass airbag off” indicator
will light and stay lit to remind you that the front passenger frontal
airbag is off. See Front passenger sensing system in the Airbag
supplemental restraints (SRS) section of this chapter.

Front safety belt usage sensors

The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal Safety System to tailor the airbag deployment and
safety belt pretensioner activation depending upon safety belt usage.

Front safety belt pretensioners

The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions and in side collisions. This helps increase the
effectiveness of the safety belts. In frontal collisions, the safety belt
pretensioners can be activated alone or, if the collision is of sufficient
severity, together with the front airbags.

Front safety belt energy management retractors

The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant’s forward momentum. This helps
reduce the risk of force-related injuries to the occupant’s chest by
limiting the load on the occupant. Refer to Energy management feature
section in this chapter.

Determining if the Personal Safety System is operational

The Personal Safety System uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to the Warning light and chimes section in the Instrument Cluster
chapter. Routine maintenance of the Personal Safety System is not
required.

The restraints control module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, front
passenger sensing system, and the driver seat position sensor. In
addition, the RCM also monitors the restraints warning light in the
instrument cluster. A difficulty with the system is indicated by one or
more of the following.
• The warning light will either flash or stay lit.
• The warning light will not illuminate immediately after ignition is

turned on.

• A series of five beeps will be heard. The tone pattern will repeat

periodically until the problem and warning light are repaired.

If any of these things happen, even intermittently, have the Personal
Safety System serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.

Safety restraints precautions

WARNING: Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.

WARNING: To reduce the risk of injury, make sure children sit
in a rear seating position where they can be properly restrained.

WARNING: Never let a passenger hold a child on his or her lap
while the vehicle is moving. The passenger cannot protect the

child from injury in a collision.

WARNING: All occupants of the vehicle, including the driver,
should always properly wear their safety belts, even when an

airbag supplemental restraint system (SRS) is provided.

WARNING: It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, 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 safety belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.

WARNING: In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a safety

belt.

WARNING: Each seating position in your vehicle has a specific
safety belt assembly which is made up of one buckle and one

tongue that are designed to be used as a pair. 1) Use the shoulder belt
on the outside shoulder only. Never wear the shoulder belt under the
arm. 2) Never swing the safety belt around your neck over the inside
shoulder. 3) Never use a single belt for more than one person.

WARNING: When possible, all children 12 years old and under
should be properly restrained in a rear seating position.

WARNING: Safety belts and seats can become hot in a vehicle
that has been closed up in sunny weather; they could burn a

small child. Check seat covers and buckles before you place a child
anywhere near them.

WARNING: Front and rear seat occupants, including pregnant
women, should wear safety belts for optimum protection in an

accident.

Combination lap and shoulder belts

1. Insert the belt tongue into the
proper buckle (the buckle closest to
the direction the tongue is coming
from) until you hear a snap and feel
it latch. Make sure the tongue is
securely fastened in the buckle.

2. To unfasten, press the release
button and remove the tongue from
the buckle.
