Calling are available on most
vehicles. Not all OnStar services
are available on all vehicles.
For more information see the
OnStar Owner's Guide or visit
www.onstar.com (U.S.) or
www.onstar.ca (Canada), contact
OnStar at 1-888-4-ONSTAR
(1‐888‐466‐7827) or
TTY 1‐877‐248‐2080, or
press
Qto speak with an
OnStar advisor 24 hours a day,
7 days a week.
For a full description of OnStar
services and system limitations,
see the OnStar Owner's Guide in
the glove box. OnStar service is subject to the
OnStar terms and conditions
included in the OnStar Subscriber
Information.
OnStar service cannot work unless
the vehicle is in a place where
OnStar has an agreement with a
wireless service provider for service
in that area. OnStar service also
cannot work unless the vehicle is
in a place where the wireless
service provider OnStar has hired
for that area has coverage, network
capacity and reception when the
service is needed, and technology
that is compatible with the OnStar
service. Not all services are
available everywhere, particularly
in remote or enclosed areas, or at
all times.
The OnStar system can record and
transmit vehicle information. This
information is automatically sent to
an OnStar call center when
Qis
pressed,
]is pressed, or if the
airbags or ACR system deploy.
This information usually includes
the vehicle's GPS location and, in
the event of a crash, additional
information regarding the crash that
the vehicle was involved in (e.g. the
direction from which the vehicle was
hit). When the virtual advisor feature
of OnStar hands-free calling is
used, the vehicle also sends OnStar
the vehicle's GPS location so they
can provide services where it is
located.
Location information about the
vehicle is only available if the GPS
satellite signals are unobstructed
and available.

Seats and Restraints 3-23
To move it down, press the release
button (A) and move the height
adjuster to the desired position.
You can move the height adjuster
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 pushing the button to make
sure it has locked into position.
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, near
frontal, or rear crash if the threshold
conditions for pretensioner
activation are met. And, for vehicles
with 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. See
Replacing Safety Belt System Parts
After a Crash on page 3‑27.
Rear Safety Belt Comfort
Guides
This vehicle may have rear shoulder
belt comfort guides. If not, they are
available through your dealer. The
guides may provide added safety
belt comfort for older children who
have outgrown booster seats and
for some adults. When installed and
properly adjusted, the comfort guide
positions the shoulder belt away
from the neck and head.

Seats and Restraints 3-35
Passenger Sensing
System
The vehicle has a passenger
sensing system for the right front
passenger position. The passenger
airbag status indicator will be visible
on the instrument panel when the
vehicle is started.
United States
Canada
The words ON and OFF, or the
symbol for on and off, are visible
during the system check. When the
system check is complete, the word ON or OFF, or the symbol for on or
off, will be visible. See
Passenger
Airbag Status Indicator
on
page 5‑11.
The passenger sensing system will
turn off the right front passenger
frontal airbag under certain
conditions. The driver airbags and
the roof-rail airbags are not affected
by the passenger sensing system.
The passenger sensing system
works with sensors that are part
of the right front passenger seat
and safety belt. The sensors are
designed to detect the presence
of a properly-seated occupant
and determine if the right front
passenger frontal airbag should
be enabled (may inflate) or not. According to accident statistics,
children are safer when properly
secured in a rear seat in the correct
child restraint for their weight
and size.
We recommend that children be
secured in a rear seat, including:
an infant or a child riding in a
rear-facing child restraint; a child
riding in a forward-facing child seat;
an older child riding in a booster
seat; and children, who are large
enough, using safety belts.

3-62 Seats and Restraints
Securing Child Restraints
(Right Front Seat
Position)
The vehicle has airbags. A rear
seat is a safer place to secure
a forward-facing child restraint.
SeeWhere to Put the Restraint
on
page 3‑49.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the right front
passenger frontal airbag under
certain conditions. See Passenger
Sensing System
on page 3‑35and Passenger Airbag Status
Indicatoron page 5‑11for more
information, including important
safety information.
A label on the sun visor says,
“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 right
front passenger 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 right front
passenger airbag inflates and the
passenger seat is in a forward
position.
Even if the passenger sensing
system has turned off the right
front 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.
(Continued)
WARNING (Continued)
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 right 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 3‑35for additional
information.
If the child restraint has the LATCH
system, see Lower Anchors and
Tethers for Children (LATCH
System)
on page 3‑51for how and
where to install the child restraint
using LATCH. If a child restraint is
secured using a safety belt and it
uses a top tether, see Lower
Anchors and Tethers for Children
(LATCH System)
on page 3‑51for
top tether anchor locations.

Instruments and Controls 5-9
Engine Coolant
Temperature Gauge
United StatesCanada
This gauge shows the engine
coolant temperature.
If the gauge pointer is in the shaded
area of the gauge, the engine is
too hot. It means that the engine
coolant has overheated. If the
vehicle has been operating under
normal driving conditions, pull off
the road, stop your vehicle and turn
off the engine as soon as possible.
See Engine Overheating
on
page 10‑22for more information.
