The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it’s more
likely that the fetus won’t be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is Wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, see Driver Position on page
1-30,
The right front passenger’s safety belt works the same
way
as the driver’s safety belt-except for one thing.
If you ever pull the shoulder portion of the belt out all the
way, you will engage the child restraint locking feature
which may turn
off the passenger’s frontal air bag. If this
happens unintentionally, just let the belt go back all
the way and start again.
Center Passenger Position
Second Row - Lap-Shoulder Belt
When you sit in the center seat position in the second
row you have a lap-shoulder belt which works the same
way as the rear outside seat positions. To learn how
to wear this belt, see “Lap-Shoulder Belt” under
Rear Seat Passengers on page
1-4 1.
1-39

6. To tighten the belt, feed the shoulder belt back into
the retractor while you push down on the child
restraint. If you are using a forward-facing child
restraint, you may find it helpful to use your knee to
push down on the child restraint as you tighten the
belt. You should not be able to pull more of the belt
out of the retractor once the lock has been set.
7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If your vehicle has the passenger sensing system
and you’re using a rear-facing child restraint in this
seat, check to be sure the right front passenger’s
frontal air bag is off before you begin to drive.
If the
air bag has been turned off the
off indicator will
light and stay lit when the key is turned to RUN or
START.
If the on indicator is lit, the passenger’s frontal air
bag has not been turned
off. If this ever happens,
turn off the vehicle, unbuckle the safety belt
and perform the steps to install the rear-facing
restraint again. After restarting the vehicle,
if the air
bag still doesn’t turn off, install the infant restraint
in
a rear seat position of the vehicle and have your
vehicle serviced as soon as possible.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.

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.
L
Passenger Air Bag Status Indicator - United States Passenger
Air Bag
Status Indicator
- Canada
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
