sensor Acura RSX 2003 Owner's Manual

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.’’ 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).
Sensors that can detect a
moderate to severe frontal
collision. Automatic seat belt tensioners
(see page ). 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.
If you ever have a moderate to
severe f rontal collision, the sensors
will detect the vehicle’s rapid
deceleration. If the rate of
deceleration is high enough, the
control unit will instantly inf late the
f ront airbags. Your vehicle is equipped with dual-
stage, dual-threshold airbags to help
reduce the chance of airbag-caused
injuries.

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. 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.Af ter inf lating, the f ront airbags
immediately def late, so they won’t
interf ere with the driver’s visibility,
or the ability to steer or operate
other controls.
During a f rontal crash, your seat
belts help restrain your lower body
and torso. Your airbag provides a
cushion to help restrain and protect
your head and chest.
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
mayexperiencesometemporary
discomf ort. If this occurs, get out of
the car as soon as it is safe to do so.

To get the best protection f rom the
side airbags, front seat occupants
should wear their seat belts and sit
upright and well back in their seats. If you ever have a moderate to
severe side impact, the sensors will
detect rapid deceleration and signal
the control unit to instantly inf late
either the driver’s or the passenger’s
side airbag.
Only one airbag will deploy during a
side impact. If the impact is on the
passenger’s side, the passenger’s
side airbag will deploy even if there
is no passenger.
U.S. Owners:
For additional information on how
your airbags work, see the booklet
titled
that came with your
owner’s manual.
Canadian Owners:
For additional information on how
your airbags work, ask your dealer
f or a copy of the booklet titled
Your car is equipped with side
airbags f or the driver and a front
seat passenger. The airbags are
stored in the outer edges of the f ront
seat-backs, and both are marked
‘‘SIDE AIRBAG.’’

Repair chips and scratches in the
paint as soon as you discover them.
Inspect and clean out the drain
holes in the bottom of the doors
and body.
Check the f loor coverings f or
dampness. Carpeting and f loor
mats may remain damp f or a long
time, especially in winter. This
dampness can eventually cause
the f loor panels to corrode.
Two f actors normally contribute to
causing corrosion in your car:
Moisture trapped in body cavities.
Dirtandroadsaltthatcollectsin
hollows on the underside of the
car stays damp, promoting
corrosion in that area.
Removal of paint and protective
coatings f rom the exterior and
underside of the car. Many corrosion-preventive measures
are built into your Acura. You can
help keep your car f rom corroding
by perf orming some simple periodic
maintenance:
Use a high-pressure spray to clean
the underside of your car. This is
especially important in areas that
useroadsaltinwinter.Itisalsoa
good idea in humid climates and
areas subject to salt air. Cars
equipped with ABS have a sensor
and wiring at each wheel. Be
caref ul not to damage them.
Have the corrosion-preventive
coatings on the underside of your
car inspected and repaired
periodically.

If you are planning to take your
Acura 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 Acura 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 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 Acura replacement parts or
their equivalent f or repairs. Using
lowerqualitypartsmayincreasethe
emissions f rom your car.
The emissions control systems are
covered by warranties separate from
the rest of your car. Read your
warranty manual f or more informa-
tion.
The Onboard Ref ueling Vapor
Recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .
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 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.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO and NOx produced.
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 ), nitrogen
(N ), and water vapor.
