What Makes an Airbag
Inflate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inflator. Gas from the inflator fills the
airbag causing the bag to break out
of the cover and deploy. The inflator,
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 modules in
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
first 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. See

Should an Airbag Inflate?
on
page 3‑29for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.

9-48 Driving and Operating
VIN is at the top left of the
instrument panel. SeeVehicle
Identification Number (VIN)
on
page 12‑1.
Recommended Fuel
If the vehicle has the 3.6L V6 engine
(VIN Code 7), use regular unleaded
gasoline with a posted octane
rating of 87 or higher. For best
performance or trailer towing, you
could choose to use middle grade
89 octane unleaded gasoline. If the
octane rating is less than 87, an
audible knocking noise, commonly
referred to as spark knock, might be
heard when driving. If this occurs,
use a gasoline rated at 87 octane or
higher as soon as possible. If heavy
knocking is heard when using
gasoline rated at 87 octane or
higher, the engine needs service.
If the vehicle has the 2.4L L4 engine
(VIN Code P) or the 3.5L V6 engine
(VIN Code N), use regular unleaded
gasoline with a posted octane rating
of 87 or higher. If the octane rating is less than 87, an audible knocking
noise, commonly referred to as
spark knock, might be heard when
driving. If this occurs, use a
gasoline rated at 87 octane or
higher as soon as possible. If heavy
knocking is heard when using
gasoline rated at 87 octane or
higher, the engine needs service.
Gasoline Specifications
At a minimum, gasoline should
meet ASTM specification 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. See
Fuel
Additives
on page 9‑49for
additional information.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. 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 specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle might fail a smog‐check test.
See Malfunction Indicator Lamp
on
page 5‑15. 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.

Headlamps
To replace one of the headlamp
bulbs, use the following procedure.
To replace the parking/turn signal
lamp bulb, see Front Turn Signal

page 10‑5for more information.
2. Remove the two screws from the top of the front fascia and grille.
They are inboard of the
headlamp assembly.
3. Remove the three screws retaining the headlamp
assembly. 4. Insert a flat blade tool through
the opening in the top. Make
