2009 GMC ENVOY Owner's Manual

Safety Belt Pretensioners
This vehicle has safety belt pretensioners for the
front outboard occupants. Although the safety belt
pretensioners cannot be seen, they are part of the safety
belt assembly. They can help tighten the safety belts
during the early stages of a moderate to severe frontal
or near frontal crash if the threshold conditions for
pretensioner activation are met. And, if your vehicle has
side impact airbags, safety belt pretensioners can help
tighten the safety belts in a side crash or a rollover event.
Pretensioners work only once. If the pretensioners
activate in a crash, they will need to be replaced, and
probably other new parts for the vehicle’s safety
belt system. SeeReplacing Restraint System Parts
After a Crash on page 1-71.
Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide added
safety belt comfort for older children who have outgrown
booster seats and for some adults. When installed on
a shoulder belt, the comfort guide positions the belt
away from the neck and head.There is one guide for each outside passenger position
in the rear seat. Here is how to install the comfort
guide to the shoulder belt:
1. Slide the guide off of its storage clip located
between the interior body and the seatback or from
the storage pocket on the side of the seat.
2. Place the guide over the belt and insert the two
edges of the belt into the slots of the guide.

3. Be sure that the belt is not twisted and it lies at.
The elastic cord must be under the belt and the
guide on top.
{CAUTION:
A safety belt that is not properly worn may not
provide the protection needed in a crash. The
person wearing the belt could be seriously injured.
The shoulder belt should go over the shoulder and
across the chest. These parts of the body are best
able to take belt restraining forces.
1-30

4. Buckle, position, and release the safety belt as
described previously in this section. Make sure
that the shoulder belt crosses the shoulder.
To remove and store the comfort guide, squeeze the
belt edges together so that the safety belt can be
removed from the guide. Slide the guide back onto its
storage clip located between the interior body and
the seatback or into the storage pocket on the side of
the seat.
Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely to be
seriously injured if they do not wear safety belts.
A pregnant woman should wear a lap-shoulder belt, and
the lap portion should be worn as low as possible,
below the rounding, throughout the pregnancy.
The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it is more
likely that the fetus will not be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.

Safety Belt Extender
If the safety belt will fasten around you, you should
use it.
But if a safety belt is not long enough, your dealer/
retailer will order you an extender. When you go in to
order it, take the heaviest coat you will wear, so
the extender will be long enough for you. To help avoid
personal injury, do not let someone else use it, and
use it only for the seat it is made to t. The extender has
been designed for adults. Never use it for securing
child seats. To wear it, attach it to the regular safety belt.
For more information, see the instruction sheet that
comes with the extender.
Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle’s safety belts.
1-32

The manufacturer’s instructions that come with the
booster seat state the weight and height limitations for
that booster. Use a booster seat with a lap-shoulder belt
until the child passes the below t test:
Sit all the way back on the seat. Do the knees bend
at the seat edge? If yes, continue. If no, return to
the booster seat.
Buckle the lap-shoulder belt. Does the shoulder belt
rest on the shoulder? If yes, continue. If no, try
using the rear safety belt comfort guide. See “Rear
Safety Belt Comfort Guides” underLap-Shoulder
Belt on page 1-27for more information. If the
shoulder belt still does not rest on the shoulder,
then return to the booster seat.
Does the lap belt t low and snug on the hips,
touching the thighs? If yes, continue. If no, return to
the booster seat.
Can proper safety belt t be maintained for the
length of the trip? If yes, continue. If no, return
to the booster seat.
If you have the choice, a child should sit in a
position with 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: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 t snugly below the
hips, just touching the top of the thighs. This applies
belt force to the child’s pelvic bones in a crash. It
should never be worn over the abdomen, which
could cause severe or even fatal internal injuries in
a crash.
Also see “Rear Safety Belt Comfort Guides” under
Lap-Shoulder Belt on page 1-27.
According to accident statistics, children and infants are
safer when properly restrained in a child restraint
system or infant restraint system secured in a rear
seating position.
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.
1-33

{CAUTION:
Never do this.
Never allow two children to wear the same safety
belt. The safety belt can not properly spread the
impact forces. In a crash, the two children can be
crushed together and seriously injured. A safety
belt must be used by only one person at a time.
{CAUTION:
Never do this.
Never allow a child to wear the safety belt with the
shoulder belt behind their back. A child can be
seriously injured by not wearing the lap-shoulder
belt properly. In a crash, the child would not be
restrained by the shoulder belt. The child could
move too far forward increasing the chance of
head and neck injury. The child might also slide
under the lap belt. The belt force would then be
applied right on the abdomen. That could cause
serious or fatal injuries. The shoulder belt should
go over the shoulder and across the chest.
1-34

Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.
{CAUTION:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Never leave
children unattended in a vehicle and never allow
children to play with the safety belts.
Airbags plus lap-shoulder belts offer protection for
adults and older children, but not for young children and
infants. Neither the vehicle’s safety belt system nor
its airbag system is designed for them. Every time
infants and young children ride in vehicles, they should
have the protection provided by appropriate child
restraints.
Children who are not restrained properly can strike
other people, or can be thrown out of the vehicle.
1-35

{CAUTION:
Never do this.
Never hold an infant or a child while riding in a
vehicle. Due to crash forces, an infant or a child
will become so heavy it is not possible to hold it
during a crash. For example, in a crash at only
25 mph (40 km/h), a 12 lb (5.5 kg) infant will
suddenly become a 240 lb (110 kg) force on a
person’s arms. An infant should be secured in an
appropriate restraint.
