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 shoulder belt comfort guides will 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.
There is one guide available for each outside passenger
position in the rear seat. Here’s how to install a
comfort guide and use the safety belt:
1. For the second row, remove the guide from its
storage clip on the trim panel near the side of
the seatback.
For the third row, remove the guide from its storage
clip on the side of the seatback.2. Place the guide over the belt and insert the
two edges of the belt into the slots of the guide.

Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle’s safety belts.
If you have the choice, a child should sit in a seat that
has a lap-shoulder belt and get the additional restraint a
shoulder belt can provide.
Q:What is the proper way to wear safety belts?
A: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
shouldfit 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.
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.

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 designed to
improve thefit of the vehicle’s safety belt system. Some
booster seats have a shoulder belt positioner, and
some high-back booster seats have afive-point harness.
A booster seat can also help a child to see out the
window.

In Canada, the law requires that forward-facing child
restraints have a top strap, and that the strap be
anchored. In the United States, some child restraints
also have a top strap. If your child restraint has a
top strap, it should be anchored.
Anchor the top strap to one of the following anchor
points. Be sure to use an anchor point located on the
same side of the vehicle as the seating position
where the child restraint will be placed.
If you have an adjustable head restraint, route the top
strap under it.
Once you have the top strap anchored, you’ll be ready
to secure the child restraint itself. Tighten the top
strap when and as the child restraint manufacturer’s
instructions say.Top Strap Anchor Location
Tahoe/Suburban/Yukon/Yukon XL models without
rear seats:Top strap anchor loops are located at
the bottom rear of the front seat cushion for the right
front passenger’s position.
Anchor the top strap to this bracket. Once you have the
top strap anchored, you’ll be ready to secure the
child restraint itself.Suburban/Yukon XL Models without Rear Seats

Tahoe/Suburban/Yukon/Yukon XL models with rear
seats:A child restraint with a top strap should only
be used in the second or third row. Don’t use a
child restraint with a top strap in the front seat because
there’s no place to anchor the top strap.
An anchor loop bracket for a top strap is located at the
bottom rear of the seat cushion for each seating
position in the second row, and for the center seating
position in the third row.

You’ll be using the lap-shoulder belt. SeeTop Strap on
page 1-54if 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. Because your vehicle has a right front passenger
air bag, always move the seat as far back as it will
go before securing a forward-facing child restraint.
SeePower Seats on page 1-4orManual Seats
on page 1-3.
If your vehicle has the passenger sensing system
and you are using a rear-facing child restraint in this
seat, make sure the frontal air bag is off. See
Passenger Sensing System on page 1-81.
When the passenger sensing system has turned off
the right front passenger’s frontal air bag, the off
indicator on the inside rearview mirror will light and
stay lit when you turn the ignition to RUN or
START.
2. Put the restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

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 driver’s and right front passenger’s frontal
air bags are not designed to inflate in rollovers, rear
impacts, or in many side impacts because inflation
would not help the occupant.
Seat Position Sensors
Vehicles 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.
Side Impact Air Bags
Your vehicle may or may not have a side impact air
bag. SeeAir Bag Systems on page 1-70. Side impact air
bags are designed to inflate in moderate to severe
side crashes. A side impact air bag will inflate if
the crash severity is above the system’s designed
“threshold level.”The threshold level can vary with
specific vehicle design. Side impact air bags are
not designed to inflate in frontal or near-frontal impacts,
rollovers or rear impacts, because inflation would not
help the occupant. A side impact air bag will only deploy
on the side of the vehicle that is struck.
Air Bag Systems
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.
For frontal air bags, inflation is determined by the angle
of the impact and how quickly the vehicle slows down
in frontal and near-frontal impacts. For side impact
air bags, inflation is determined by the location
and severity of the impact.
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 with Your Four-Wheel Drive Vehicle in the
Index for tips on off-road driving.
