gas type SATURN VUE HYBRID 2009 Owners Manual

is determined by the location and
severity of the side impact. In
a rollover event, roof-rail airbag
deployment is determined by
the direction of the roll.
What Makes an Airbag
Inate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inator. Gas from the inator lls
the airbag causing the bag to break
out of the cover and deploy. The
inator, the airbag, and related
hardware are all part of the airbag
module.
Frontal airbag modules are located
inside the steering wheel and
instrument panel. For vehicles with
seat-mounted side impact airbags,
there are airbag modules in the side
of the front seatbacks closest to
the door. For vehicles with roof-rail
airbags, there are airbag modulesin the ceiling of the vehicle, near the
side windows that have occupant
seating positions.
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 rst and second rows. 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. SeeWhen
Should an Airbag Inflate? on
page 1-45for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.

Fuel
Use of the recommended fuel is an
important part of the proper
maintenance of this vehicle. To help
keep the engine clean and
maintain optimum vehicle
performance, we recommend the
use of gasoline advertised as
TOP TIER Detergent Gasoline.
Gasoline Octane
Use regular unleaded gasoline with
a posted octane rating of 87 or
higher. If the octane rating is less
than 87, you might notice an audible
knocking noise when you drive,
commonly referred to as spark
knock. If this occurs, use a gasoline
rated at 87 octane or higher as
soon as possible. If you are using
gasoline rated at 87 octane or higher
and you hear heavy knocking, the
engine needs service.
Gasoline Specications
At a minimum, gasoline should
meet ASTM specication D 4814 in
the United States or CAN/CGSB-3.5
or 3.511 in Canada. Some
gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeAdditives on
page 5-5for additional information.
California Fuel
If the vehicle is certied to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specications. See
the underhood emission control
label. If this fuel is not available in
states adopting California emissions
standards, the vehicle will operate
satisfactorily on fuels meeting federal
specications, but emission control
system performance might be
affected. The malfunction indicator
lamp could turn on and the vehiclemight fail a smog-check test. See
Malfunction Indicator Lamp on
page 3-30. If this occurs, return to
your authorized dealer/retailer for
diagnosis. If it is determined that the
condition is caused by the type of
fuel used, repairs might not be
covered by the vehicle warranty.
Additives
To provide cleaner air, all gasolines
in the United States are now
required to contain additives that
help prevent engine and fuel system
deposits from forming, allowing
the emission control system to work
properly. In most cases, you
should not have to add anything to
the fuel. However, some gasolines
contain only the minimum amount of
additive required to meet U.S.
Environmental Protection Agency
regulations. To help keep fuel
injectors and intake valves clean, or
if the vehicle experiences problems
due to dirty injectors or valves,
look for gasoline that is advertised
as TOP TIER Detergent Gasoline.
