Cleaning the Mirror
Do not spray glass cleaner directly
on the mirror. Use a soft towel
dampened with water.
Windows
{WARNING
Leaving children, helpless
adults, or pets in a vehicle
with the windows closed is
dangerous. They can be
overcome by the extreme heat
and suffer permanent injuries
or even death from heat stroke.
Never leave a child, a helpless
adult, or a pet alone in a vehicle,
especially with the windows
closed in warm or hot weather.
The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear
window is down and the front
windows are up. To reduce the
sound, open either a front window
or the sunroof (if equipped).

Seats and Restraints 3-33
To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position.
Before a door is closed, be sure
the safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger positions.
Adjust the height so the shoulder
portion of the belt is on the
shoulder and not falling off of it.
The belt should be close to, but
not contacting, the neck. Improper
shoulder belt height adjustment
could reduce the effectiveness of
the safety belt in a crash. SeeHow
to Wear Safety Belts Properly on
page 3‑25.
Squeeze the buttons (A) on the
sides of the height adjuster and
move the height adjuster to the
desired position.
The adjuster can be moved up just
by pushing up on the shoulder belt
guide.
After the adjuster is set to the
desired position, try to move it
down without squeezing the buttons
to make sure it has locked into
position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for 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, near frontal, or rear crash
if the threshold conditions for
pretensioner activation are met.
And, if the 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,
the pretensioners and probably
other parts of the vehicle's safety
belt system will need to be replaced.
See Replacing Safety Belt System
Parts After a Crash on page 3‑38.

How Does an Airbag
Restrain?
In moderate to severe frontal or
near frontal collisions, even belted
occupants can contact the steering
wheel or the instrument panel. In
moderate to severe side collisions,
even belted occupants can contact
the inside of the vehicle.
Airbags supplement the protection
provided by safety belts. Frontal
airbags distribute the force of the
impact more evenly over the
occupant's upper body, stopping
the occupant more gradually.
Seat‐mounted side impact and
roof-rail airbags distribute the force
of the impact more evenly over the
occupant's upper body.Rollover capable roof-rail airbags
are designed to help contain the
head and chest of occupants in
the outboard seating positions in
the first, second, and third rows,
if equipped with a third row seat.
The rollover capable roof-rail
airbags are designed to help
reduce the risk of full or partial
ejection in rollover events, although
no system can prevent all such
ejections.
But airbags would not help in
many types of collisions, primarily
because the occupant's motion is
not toward those airbags. See
When
Should an Airbag Inflate? on
page 3‑43 for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See After
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated.
Roof-rail airbags may still be at
least partially inflated for some
time after they deploy. Some
components of the airbag module
may be hot for several minutes. For
location of the airbag modules, see
What Makes an Airbag Inflate? on
page 3‑44.
The parts of the airbag that come
into contact with you may be
warm, but not too hot to touch.

A thick layer of additional material,
such as a blanket or cushion,
or aftermarket equipment such as
seat covers, seat heaters, and
seat massagers, can affect how
well the passenger sensing system
operates. We recommend that
you not use seat covers or other
aftermarket equipment except when
approved by GM for your specific
vehicle. SeeAdding Equipment to
the Airbag-Equipped Vehicle on
page 3‑52 for more information
about modifications that can affect
how the system operates.
The on indicator may be lit if
an object, such as a briefcase,
handbag, grocery bag, laptop,
or other electronic device, is put
on an unoccupied seat. If this is
not desired, remove the object from
the seat.{WARNING
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer and the service manual have
information about servicing the
vehicle and the airbag system. To
purchase a service manual, see
Service Publications Ordering
Information on page 13‑12.
{WARNING
For up to 10 seconds after the
ignition is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.

{WARNING
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.
{WARNING
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(Continued)
WARNING (Continued)
of the retractor to set the lock,
if the 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,
before folding the seat.
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.
2. If the child restraint manufacturer recommends that the top tether
be attached, attach and tighten
the top tether to the top tether
anchor, if the vehicle has one.
