Passenger Sensing System
If your rearview mirror has one of the indicators pictured
in the following illustrations, your vehicle has a passenger
sensing system. The indicator will be visible when you
turn your ignition key
to START or RUN. The words ON
and OFF or the symbol for on and off, will be visible on
the rearview mirror during the system check. When the
system check
is complete, either the word ON or the word
OFF, or the symbol for on or the symbol for off will be
visible. See Passenger
Air Bag Status Indicator on
page 3-32. If your rearview mirror doesn’t have either of
the indicators pictured, then your vehicle doesn’t have the
passenger sensing system.

The passenger sensing system will turn off the right
front passenger’s frontal air bag under certain
conditions. The driver’s air bag and the side air bags
are not part
of the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety
belt. The sensors are designed to detect the presence of
a properly-seated occupant and determine
if the
passenger’s frontal air bag should be enabled
(may inflate) or not.
Accident statistics show that children are safer
if they
are restrained in the rear rather than the front seat.
General Motors, therefore, recommends that child
restraints be secured in a rear seat including an infant
riding in a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding in a
booster seat. Never put a child in rear facing child

restraint in the right front passenger seat unless your
vehicle has the passenger sensing system and the

off. Never put

seat
I Inless the air bag is off.

A l-..jld in a rear-facing -..ild restraint can be
seriously injured or killed
if the right front
passenger’s air bag inflates. This is because
the back of the rear facing child restraint
would be very close to the inflating air bag. Be
sure the air bag is
off before using a
rear-facing child restraint in the right front seat
position.
Even though the passenger sensing system
is
designed to turn off the passenger’s frontal air
bag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one
can guarantee that an air bag will not deploy
under some unusual circumstance,
CAUTION: (Continued) even though
it is
turned off. General Motors
therefore recommends that rear-facing child restraints be secured in the rear seat whenever
possible, even if the air bag is
off.
The passenger sensing system is designed to turn off
the right front passenger’s frontal air bag if:
the right front passenger seat is unoccupied,
the system determines that an infant is present in a
rear-facing infant seat,
the system determines that a small child is present
in
a forward-facing child restraint,
the system determines that a small child is present
in a booster seat,

smaller person, such as a child who has outgrown
child restraints.

system or the passenger sensing system.

When the passenger sensing system has turned off the
passenger’s frontal air bag, the
off indicator will light
and stay lit to remind you that the air bag is
off.
The passenger sensing system is designed to turn off
the passenger’s frontal air bag when a rear facing infant
seat, a forward-facing child restraint or a booster seat
is detected. If the child restraint has been installed
and the on indicator is lit, turn the vehicle
off, remove
the child restraint from the vehicle and reinstall the
restraint following the child restraint manufacturer’s
directions and refer to Securing
a Child Restraint in the
Right Front Seat Position
on page 7-68 of this manual.
If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, secure the child in
the child restraint in a rear seat position in the vehicle
and check with your dealer.
The passenger sensing system is designed to enable
(may inflate) the right front passenger’s frontal air
bag anytime the system senses that a person of adult
size is sitting properly in the right front passenger’s seat.
When the passenger sensing system has allowed the
air bag to be enabled, the on indicator will light and stay
lit to remind you that the air bag is active. For
some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn
off the right front passenger’s
frontal air bag, depending upon the person’s seating
posture and body build. Everyone in your vehicle
who has outgrown child restraints should wear a safety
belt properly
- - whether or not there is an air bag
for that person.
If a person of adult-size is sitting in the right front
passenger’s seat, but the
off indicator is lit, it could be
because that person isn’t sitting properly in the seat. If
this happens, turn the vehicle
off and ask the person to
place the seatback in the full upright position, then sit
upright in the seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the vehicle
and have the person remain in this position for about two
minutes. This will allow the system to detect that person
and then enable the passenger’s air bag.
