3. When the child restraint isremoved, reinstall the head
restraint before the seating
position is used.
{Warning
With head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly.
4. Route the top tether of the child restraint under the head
restraint.
5. With the head restraint facingrearward, insert the head
restraint posts into the holes in
the top of the seatback.
6. Push the head restraint down.
7. Try to move the head restraint to make sure that it is locked in
place.
Replacing LATCH System
Parts After a Crash
{Warning
A crash can damage the LATCH
system in the vehicle. A damaged
LATCH system may not properly
secure the child restraint,
resulting in serious injury or even
death in a crash. To help make
sure the LATCH system is
working properly after a crash,
see your dealer to have the
system inspected and any
necessary replacements made as
soon as possible.
If the vehicle has the LATCH system
and it was being used during a
crash, new LATCH system parts
may be needed.
New parts and repairs may be
necessary even if the LATCH
system was not being used at the
time of the crash.

3-58 Seats and Restraints
6. If the child restraint has a toptether, 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) on page 3-47.
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) on page 3-47 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 on
page 3-46.
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 on
page 3-33 andPassenger Airbag
Status Indicator on page 5-19 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

Warning (Continued)
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
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
on page 3-33 for additional
information.
If the child restraint uses a top
tether, see Lower Anchors and
Tethers for Children (LATCH
System) on page 3-47 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 on page 5-19.
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.

the full retracted position.
To remove the cover:
1. Let the cover go all the way into the holder.
2. Then, grasping the driver side cover end cap, push the cover
end cap toward the passenger
side of the vehicle.
3. Swing the cover rearward and take it out of the vehicle.
To put the cover in the vehicle:
1. Make sure the cover slot in the holder faces rearward with the
round surface facing down.
2. Then, hold the cover at an angle and place the cover end cap into
the slot in the passenger side
trim panel.
3. Move the other end of the cover forward and hold it next to the
driver side trim panel slot.
4. Press the end caps in, to allow the cover to fit into the trim slot. 5. Pull lightly on the cover holder to
make sure it is secure.
On long wheelbase models there
are two cover positions. The slots
furthest forward allow the cover to
be used if the third seat is removed
or folded down. The cover can be
installed and removed from
either side.
Cargo Tie-Downs
If equipped with cargo tie-downs in
the rear cargo area, these can be
used to strap cargo down and keep
it from moving inside the vehicle.
Convenience Net
Use the convenience net, located in
the rear, to store small loads as far
forward as possible. The net should
not be used to store heavy loads.

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 on page 9-15.
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.

Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working.
Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Waiting to do repairs can be
costly and even dangerous.
