2003 GMC SIERRA DENALI seats

Rear Safety Belt Comfort Guides for
Children and Small Adults
Your vehicle may have this feature already. If it doesn't,
you can get it from any
GM dealer.
Rear seat comfort guides provide added safety belt
comfort for older children who have outgrown booster
seats and for small adults. When installed on a shoulder
belt, the comfort guide better positions the belt away
from the neck and head.
To unlatch the belt, just push the button on the buckle.

Accident statistics show that children are safer if they
are restrained in the rear seat.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown
out of the vehicle. Older children need to use safety
belts properly.
Child Restraints
Older Children
Q:
A:
Older children who have outgrown booster seats should
wear the vehicle’s safety belts. What
is the proper
way to wear safety belts?
If possible, an older child should wear a
lap-shoulder belt and get the additional restraint a
shoulder belt can provide. The shoulder belt
should not cross the face or neck. The lap belt
should
fit snugly below the hips, just touching the
top of the thighs.
It should never be worn over
the abdomen, which could cause severe or even
fatal internal injuries in
a crash.
If you have the choice, a child should sit in a seat that
has a lap-shoulder belt to get the additional restraint
a shoulder belt can provide.

A forward-facing child seat (C-E) provides restraint for
the child’s body with the harness and also sometimes
with surfaces such as T-shaped or shelf-like shields.

A booster seat (F-G) is a child restraint desiqned to
improve the fit of the vehicle’s safety belt system. Some
booster seats have a shoulder belt positioner, and
some high-back booster seats have a five-point harness.
A booster seat can also help a child to see out the
window.

The passenger sensing system is designed to turn off
the right front passenger’s frontal air bag when a
rear facing child restraint is in the right front seat. In
addition to the passenger sensing system, you may use
the AIR BAG
OFF switch located on the instrument
panel to turn the air bag
off. Never put a rear facing child
restraint in the right front passenger seat unless the
air bag is
off. Here’s why:
A child in a rear-facing child 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.
CAUTION: (Continued)
’ 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, 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.
You’ll be using the lap-shoulder belt. See Top Strap on
page
1-40 if the child restraint has one. Be sure to
follow the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s air bag. If
you are using a rear-facing child restraint in this seat,
make sure the air bag is turned
off. See Air Bag Off
Switch on page 1-64 and Passenger Sensing
System
on page 1-68. Always move the seat as far
back as it will
go before securing the child restraint in
this seat. See ‘Seats” in the Index.

When Should an Air Bag Inflate?
An air bag is designed to inflate in a moderate to severe
frontal, or near-frontal crash. The air bag will inflate
only
if the impact speed is above the system’s designed
“threshold level.”
In addition, your vehicle has “dual stage” frontal air
bags, which adjust the amount of restraint according to
crash severity. For moderate frontal impacts, these
air bags inflate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
If the front of your vehicle goes straight into a wall that
doesn’t move or deform, the threshold level for the
reduced deployment is about
10 to 16 mph
(16 to 25 km/h), and the threshold level for a full
deployment is about
20 to 25 mph (32 to 40 km/h). The
threshold level can vary, however, with specific
vehicle design,
so that it can be somewhat above or
below this range.
If your vehicle strikes something that will move or
deform, such as a parked car, the threshold level will be
higher. The air bag is not designed to inflate in
rollovers, rear impacts, or in many side impacts because
inflation would not help the occupant.
In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were. Inflation
is determined by the angle of the impact and
how quickly the vehicle slows down in frontal or
near-frontal impacts.
The air bag system
is designed to work properly under
a wide range
of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain.
As always, wear your safety belt. See “Off-Road
Driving” in the Index for more tips on off-road driving.
Seat Position Sensors
Vehicle’s with dual stage air bags are also equipped
with special sensors which enable the sensing system to
monitor the position of both the driver and passenger
front seats. The seat position sensor provides
information which is used to determine
if the air bags
should deploy at a reduced level or at full depoyment.
What Makes an Air Bag Inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. The
sensing system triggers a release of gas from the
inflator, which inflates the air bag. The inflator, air bag,
and related hardware are all part of the air bag
modules inside the steering wheel and in the instrument
panel in front of the right front passenger.
