Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
Here is how to wear a lap-shoulder
belt properly.
1. Adjust the seat so you can sit up
straight. To see how, see “Seats”
in the Index.
2. Pick up the latch plate and pull
the belt across you. Do not let
it get twisted.The lap-shoulder belt may lock if
you pull the belt across you
very quickly. If this happens,
let the belt go back slightly
to unlock it. Then pull the belt
across you more slowly.
If you ever pull the shoulder
portion of a passenger belt out all
the way, you may engage the
child restraint locking feature. If
this happens, just let the belt go
back all the way and start again.
3. Push the latch plate into the
buckle until it clicks.Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, seeSafety
Belt Extender on page 1-17.
Make sure the release button on
the buckle is positioned so
you would be able to unbuckle
the safety belt quickly if
necessary.
4. To make the lap part tight, pull
up on the shoulder belt.
It may be necessary to pull
stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.
1-14 Seats and Restraints
2008 - Pontiac G8 Owner Manual
{CAUTION
Do not attach more than one
child restraint to a single
anchor. Attaching more than
one child restraint to a single
anchor could cause the anchor
or attachment to come loose or
even break during a crash. A
child or others could be
injured. To reduce the risk of
serious or fatal injuries during
a crash, attach only one child
restraint per anchor.
{CAUTION
Children can be seriously
injured or strangled if a
shoulder belt is wrapped
around their neck and the
safety belt continues to tighten.
Buckle any unused safety belts
behind the child restraint so
children cannot reach them.
Pull the shoulder belt all the
way out of the retractor to set
the lock, if your vehicle has
one, after the child restraint has
been installed.
Notice:Do not let the LATCH
attachments rub against the
vehicle’s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to
avoid rubbing the LATCH
attachments.Do not fold the empty rear seat
with a safety belt buckled.
This could damage the safety belt
or the seat. Unbuckle and
return the safety belt to its stowed
position.
1. Attach and tighten the lower
attachments to the lower
anchors. If the child restraint
does not have lower attachments
or the desired seating position
does not have lower anchors,
secure the child restraint with the
top tether and the safety belts.
Refer to your child restraint
manufacturer instructions and the
instructions in this manual.
1.1. Find the lower anchors for
the desired seating position.
1.2. Put the child restraint on
the seat.
1.3. Attach and tighten the lower
attachments on the child
restraint to the lower
anchors.

Make sure the release button is
positioned so you would be
able to unbuckle the safety belt
quickly if necessary.
4. Pull the rest of the shoulder belt
all the way out of the retractor to
set the lock.5. To tighten the belt, push down
on the child restraint, pull the
shoulder portion of the belt
to tighten the lap portion of the
belt, and feed the shoulder
belt back into the retractor. If you
are using a forward-facing
child restraint, you may nd it
helpful to use your knee to push
down on the child restraint as
you tighten the belt.6. If your child restraint has a top
tether, follow the child restraint
manufacturer’s instructions
regarding the use of the top
tether. SeeLower Anchors and
Tethers for Children (LATCH)
on page 1-40for more
information.
7. Push and pull the child restraint
in different directions to be sure
it is secure.
To remove the child restraint,
unbuckle the vehicle’s safety belt
and let it go back all the way. If the
top tether is attached to a top
tether anchor, disconnect it.
Seats and Restraints 1-47
2008 - Pontiac G8 Owner Manual
Do not secure a child seat in a
position without a top tether anchor
if a national or local law requires
that the top tether be anchored, or if
the instructions that come with
the child restraint say that the top
strap must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether
be attached.
You will be using the lap-shoulder
belt to secure the child restraint in
this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back as it
will go before securing the
forward-facing child restraint.
When the passenger sensing
system has turned off the
right front passenger frontal
airbag, the off indicator on the
passenger airbag status indicator
should light and stay lit when
the vehicle is started. See
Passenger Airbag Status
Indicator on page 4-14.2. Put the child 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. Push the latch plate into the
buckle until it clicks.
Make sure the release button is
positioned so you would be
able to unbuckle the safety belt
quickly if necessary.5. Pull the rest of the shoulder belt
all the way out of the retractor to
set the lock.

Doors and Locks
Door Locks
{CAUTION
Unlocked doors can be
dangerous.
Passengers, especially
children, can easily open
the doors and fall out of a
moving vehicle. When a door
is locked, the handle will not
open it. You increase the
chance of being thrown out
of the vehicle in a crash if
the doors are not locked. So,
wear safety belts properly
and lock the doors whenever
you drive.
(Continued)
CAUTION (Continued)
Young children who get into
unlocked vehicles may be
unable to get out. A child can
be overcome by extreme heat
and can suffer permanent
injuries or even death from
heat stroke. Always lock your
vehicle whenever you leave it.
Outsiders can easily enter
through an unlocked door
when you slow down or stop
your vehicle. Locking your
doors can help prevent this
from happening.
Manual Door Locks

from the outside using the key. Turn
the key counter-clockwise once to
unlock the driver door, and twice to
unlock all doors.
Lock all doors manually from the
outside by turning the key clockwise.
Lock and unlock the doors
manually from inside the vehicle
using the knob on the door. Do not
use the manual door lock knob
when the door is open.
