2009 BUICK ENCLAVE sensor

Frontal airbags may inate at
different crash speeds. For example:
If the vehicle hits a stationary
object, the airbags could
inate at a different crash
speed than if the vehicle hits a
moving object.
If the vehicle hits an object that
deforms, the airbags could
inate at a different crash speed
than if the vehicle hits an
object that does not deform.
If the vehicle hits a narrow object
(like a pole), the airbags could
inate at a different crash speed
than if the vehicle hits a wide
object (like a wall).
If the vehicle goes into an object
at an angle, the airbags could
inate at a different crash speed
than if the vehicle goes straight
into the object.
Thresholds can also vary with
specic vehicle design.Frontal airbags are not intended to
inate during vehicle rollovers, rear
impacts, or in many side impacts.
In addition, the vehicle has
dual-stage frontal airbags.
Dual-stage airbags adjust the
restraint according to crash severity.
The vehicle has electronic frontal
sensors, which help the sensing
system distinguish between a
moderate frontal impact and a more
severe frontal impact. For moderate
frontal impacts, dual-stage airbags
inate at a level less than full
deployment. For more severe frontal
impacts, full deployment occurs.
The vehicle has seat-mounted side
impact and roof-rail airbags. See
Airbag System on page 1-45.
Seat-mounted side impact and
roof-rail airbags are intended
to inate in moderate to severe side
crashes. In addition, these roof-rail
airbags are intended to inate during
a rollover or in a severe frontal
impact. Seat-mounted side impact
and roof-rail airbags will inate if the
crash severity is above thesystem’s designed threshold level.
The threshold level can vary
with specic vehicle design.
Seat-mounted side impact airbags
are not intended to inate in
frontal impacts, near-frontal impacts,
rollovers, or rear impacts. Roof-rail
airbags are not intended to inate in
rear impacts. A seat-mounted
side impact airbag is intended to
deploy on the side of the vehicle that
is struck. Both roof-rail airbags
will deploy when either side of the
vehicle is struck, or if the sensing
system predicts that the vehicle
is about to roll over, or in a severe
frontal impact.
In any particular crash, no one can
say whether an airbag should
have inated simply because of the
damage to a vehicle or because
of what the repair costs were.
For frontal airbags, ination is
determined by what the vehicle hits,
the angle of the impact, and how
quickly the vehicle slows down. For
seat-mounted side impact and
roof-rail airbags, deployment

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.The words ON and OFF, or the
symbol for on and off, are visible
during the system check. If you are
using remote start, if equipped,
to start the vehicle from a distance,
you may not see the system
check. When the system check is
complete, either the word ON
or OFF, or the symbol for on or off,
will be visible. SeePassenger
Airbag Status Indicator on
page 3-31.
The passenger sensing system
turns off the right front passenger
frontal airbag under certain
conditions. The driver airbag,
seat-mounted side impact airbagsand 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.
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 inate)
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. United States

Adding Equipment to
Your Airbag-Equipped
Vehicle
Q:Is there anything I might add
to or change about the
vehicle that could keep the
airbags from working
properly?
A:Yes. If you add things that
change the vehicle’s frame,
bumper system, height, front end
or side sheet metal, they may
keep the airbag system from
working properly. Changing or
moving any parts of the front
seats, safety belts, the airbag
sensing and diagnostic module,
steering wheel, instrument
panel, roof-rail airbag modules,
ceiling headliner or pillar
garnish trim, front sensors, side
impact sensors, rolloversensor module, or airbag wiring
can affect the operation of
the airbag system.
In addition, the vehicle has a
passenger sensing system
for the right front passenger
position, which includes sensors
that are part of the passenger
seat. The passenger sensing
system may not operate properly
if the original seat trim is
replaced with non-GM covers,
upholstery or trim, or with
GM covers, upholstery or trim
designed for a different vehicle.
Any object, such as an
aftermarket seat heater or a
comfort enhancing pad or device,
installed under or on top of the
seat fabric, could also interfere
with the operation of the
passenger sensing system. This
could either prevent properdeployment of the passenger
airbag(s) or prevent the
passenger sensing system from
properly turning off the
passenger airbag(s). See
Passenger Sensing System on
page 1-52.
