Your Supplemental Restraint System
(SRS) includes:Two f ront airbags. The driver’s
airbag is stored in the center of
the steering wheel; the f ront
passenger’sairbagisstoredinthe
dashboard. Both are marked ‘‘SRS
AIRBAG.’’
Automatic seat belt tensioners
that tighten the front seat belts
during a moderate to severe
f rontal collision. If you ever have a moderate to
severe f rontal collision, the sensors
will detect rapid deceleration and
signal the control unit to instantly
inflate the airbags and activate the
automatic seat belt tensioners.
Sensors that can detect a
moderate to severe frontal
collision.
A sophisticated electronic system
that continually monitors and
records inf ormation about the
sensors, the control unit, the
airbag activators, and driver and
passenger seat belt use when the ignition is ON (II).
An indicator light on the
instrument panel that alerts you to
a possible problem with the
system (see page ).
Emergency backup power in case
your car’s electrical system is
disconnected in a crash.

Af ter inf lating, the airbags
immediately def late, so they won’t
interf ere with the driver’s visibility,
or the ability to steer or operate
other controls.
The total time for inflation and
def lation is approximately one-tenth
of a second, so f ast that most
occupants are not aware that the
airbags deployed until they see them
lying in their laps.After a crash, you may see what
looks like smoke. This is actually
powder f rom the airbag’s surf ace.
Although the powder is not harmf ul,
people with respiratory problems
may experience some temporary
discomf ort. If this occurs, get out of
the car as soon as it is safe to do so.
For additional information on how
your airbags work, see the booklet
titled
that came with your
owner’s manual.
During a crash, your seat belt helps
restrain your lower body and torso,
while the tensioner tightens and
locks the seat belt to help keep you
in place. Your airbag provides a
cushion to help restrain and protect
your head and chest.
Since both airbags use the same
sensors, both airbags normally
inf late at the same time. However, it
is possible f or only one airbag to
inf late.
This can occur when the severity of
a collision is at the margin, or
threshold, that determines whether
or not the airbags will deploy. In
such cases, the seat belt will provide
suf f icient protection, and the
supplemental protection of f ered by
the airbag would be minimal.
For additional information on how
your airbags work, ask your dealer

If you are planning to take your
Honda outside the U.S. or Canada,
contact the tourist bureaus in the
areas you will be traveling in to f ind
out about the availability of unleaded
gasoline with the proper octane
rating.
If unleaded gasoline is not available,
be aware that using leaded gasoline
in your Honda will af f ect perf or-
mance and fuel mileage, and damage
its emissions controls. It will no
longer comply with U.S. and
Canadian emissions regulations, and
will be illegal to operate in North
America. To bring your car back into
compliance will require the replace-
ment of several components, such as
theoxygensensorsandthethree
way catalytic converter. These re-
placements are not covered under
warranty.

The exhaust emissions controls
include three systems: PGM-FI,
Ignition Timing Control and Three
Way Catalytic Converter. These
three systems work together to
control the engine’s combustion and
minimize the amount of HC, CO, and
NOx that comes out the tailpipe. The
exhaust emissions control systems
are separate from the crankcase and
evaporative emissions control
systems.The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), dinitrogen
(N ), and water vapor.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO and NOx produced.
The PGM-FI System uses sequential
multiport f uel injection.
It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
The Engine Control Module (ECM)
or the Powertrain Control Module
(PCM) uses various sensors to
determine how much air is going
into the engine. It then controls how
much f uel to inject under all operat-
ing conditions.
The emissions control systems are
covered by warranties separate f rom
the rest of your car. Read your
warranty manual f or more inf orma-
tion.
The emissions control systems are
designed and certif ied to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Genuine Honda replacement parts or
their equivalent f or repairs. Using
lower quality parts may increase the
emissions f rom your car.
