3. Push the latch plate into thebuckle until it clicks.
If the latch plate will not go fully
into the buckle, check to see if
the correct buckle is
being used.
Position the release button on
the buckle so that the safety
belt could be quickly unbuckled
if necessary.
4. Pull the shoulder belt all theway out of the retractor to set
the lock. When the retractor
lock is set, the belt can be
tightened but not pulled out of
the retractor.
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. When
installing a forward-facing child
restraint, it may be helpful to
use your knee to push down on
the child restraint as you
tighten the belt.
Try to pull the belt out of the
retractor to make sure the
retractor is locked. If the
retractor is not locked, repeat
Steps 4 and 5. 6. If the child restraint has a top
tether, follow the child restraint
manufacturer ’s instructions
regarding the use of the top
tether. Refer to the instructions
that came with the child
restraint and see Lower
Anchors and Tethers for
Children (LATCH
System) 0105.
7. Before placing a child in the child restraint, make sure it is
securely held in place. To
check, grasp the child restraint
at the safety belt path and
attempt to move it side to side
and back and forth. When the
child restraint is properly
installed, there should be no
more than 2.5 cm (1 in) of
movement.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.
If the head restraint was removed
for a third row outboard seating
position, reinstall it before the

seating position is used. See“Head
Restraint Removal and
Reinstallation” underLower Anchors
and Tethers for Children (LATCH
System) 0105 for additional
information on reinstalling the head
restraint properly.
Securing Child Restraints
(Front Passenger Seat)
This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint 0104.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the front
outboard passenger frontal airbag
under certain conditions. See
Passenger Sensing System 092
and Passenger Airbag Status
Indicator 0141 for more information,
including important safety
information.
Never put a rear-facing child seat in
the front. This is because the risk to
the rear-facing child is so great if the
airbag deploys.
{Warning
A child in a rear-facing child
restraint can be seriously injured
or killed if the front outboard
passenger frontal airbag inflates.
This is because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the front
outboard passenger frontal airbag
inflates and the passenger seat is
in a forward position.
Even if the passenger sensing
system has turned off the front
outboard passenger frontal
airbag, no system is fail-safe. No
one can guarantee that an airbag
will not deploy under some
unusual circumstance, even
though it is turned off.
Secure rear-facing child restraints
in a rear seat, even if the airbag
is off. If you secure a
(Continued)
Warning (Continued)
forward-facing child restraint in
the front seat, always move the
front passenger seat as far back
as it will go. It is better to secure
the child restraint in a rear seat.
SeePassenger Sensing System
0 92 for additional information.
If the child restraint uses a top
tether, see Lower Anchors and
Tethers for Children (LATCH
System) 0105 for top tether anchor
locations.
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.

When using the lap-shoulder belt to
secure the child restraint in this
position, follow the instructions that
came with the child restraint and the
following instructions: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 front
outboard passenger frontal
airbag, the off indicator on the
passenger airbag status
indicator should light and stay
lit when you start the vehicle.
See Passenger Airbag Status
Indicator 0141.
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.
Tilt the latch plate to adjust the
belt, if needed.
4. Push the latch plate into thebuckle until it clicks. Position the release button on
the buckle so that the safety
belt could be quickly unbuckled
if necessary.
5. Pull the shoulder belt all the
way out of the retractor to set
the lock. When the retractor
lock is set, the belt can be
tightened but not pulled out of
the retractor.

Roof Rack System
{Warning
If something is carried on top of
the vehicle that is longer or wider
than the roof rack—like paneling,
plywood, or a mattress —the
wind can catch it while the vehicle
is being driven. The item being
carried could be violently torn off,
and this could cause a collision
and damage the vehicle. Never
carry something longer or wider
than the roof rack on top of the
vehicle unless using a GM
certified accessory carrier.
If equipped, the roof rack can be
used to load items. For roof racks
that do not have crossrails included,
GM Certified crossrails can be
purchased as an accessory. See
your dealer for additional
information.
Caution
Loading cargo on the roof rack
that weighs more than 100 kg
(220 lb) or hangs over the rear or
sides of the vehicle may damage
the vehicle. Load cargo so that it
rests evenly between the
crossrails, making sure to fasten
cargo securely.
To prevent damage or loss of cargo
when driving, check to make sure
crossrails and cargo are securely
fastened. Loading cargo on the roof
rack will make the vehicle’ s center
of gravity higher. Avoid high speeds,
sudden starts, sharp turns, sudden
braking, or abrupt maneuvers,
otherwise it may result in loss of
control. If driving for a long distance,
on rough roads, or at high speeds,
occasionally stop the vehicle to
make sure the cargo remains in its
place. Do not exceed the maximum vehicle
capacity when loading the vehicle.
For more information on vehicle
capacity and loading, see
Vehicle
Load Limits 0205.
A Center High-Mounted Stoplamp
(CHMSL) is located above the rear
window glass. Make sure items
loaded on the roof of the vehicle do
not block or damage the CHMSL.
