Supplemental Restraint System

Your car is equipped with a Supple- mental Restraint System (SRS) to
help protect the head and chest of
the driver and front seat passenger during a severe frontal collision.

This system does not replace your seat

belts. It supplements, or adds to, the
protection offered by seat belts and
other occupant protection features.
SRS Components

Your supplemental restraint system
includes:
One airbag in the steering wheel
for the driver and another in the dashboard for the passenger. Sensors that can detect a severe
frontal collision. A sophisticated electronic system
that continually monitors thesensors, control unit, airbag
activators, and all related wiring
when the ignition is ON (II). An indicator light on the instru-
ment panel to alert you to a possi-
ble problem with the system. Emergency backup power in case
your car's electrical system is disconnected in a crash. What Happens In a Crash
If you ever have a severe frontal
collision, the sensors will detect
rapid deceleration and signal the
control unit to instantly inflate the

airbags.

During a crash, your seat belts will
help to restrain your lower body and
torso. The airbags will provide a cushion to absorb crash energy and
help keep the head and chest of the driver and front passenger from
striking the interior of the car.
After inflating, the airbags will immediately deflate. The entire
process, from detection to deflation,
takes a fraction of a second. This
process occurs so quickly that you may not hear the loud noise created
by the airbag inflators, or realize
what has happened.

Driver and Passenger Safety

Not wearing a seat belt
increases the chance of serious
injury or death in a crash, even
if you have airbags.
Be sure you and your
passengers always wear seat
belts and wear them properly.ProCarManuals.comMain Menu Table of Contents s t

Gasoline

The following are the EPA-approved percentages of oxygenates:
ETHANOL (ethyl or grain alcohol)
You may use gasoline containing up to 10 percent ethanol by volume.Gasoline containing ethanol may be
marketed under the name "Gasohol."
MTBE (Methyl Tertiary Butyl Ether)
You may use gasoline containing up to 15 percent MTBE by volume.
METHANOL (methyl or wood

alcohol)

You may use gasoline containing up to 5 percent methanol by volume as
long as it also contains cosolventsand corrosion inhibitors to protect
the fuel system. Gasoline containing
more than 5 percent methanol by
volume may cause starting and/or performance problems. It may alsodamage metal, rubber and plastic
parts of your fuel system. If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
Fuel system damage or performance
problems resulting from the use of an oxygenated fuel containing more
than the percentages of oxygenates
given above are not covered under
warranty.
Driving in Foreign Countries

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 find 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 affect perfor-
mance and fuel mileage, and damage
its emissions controls. It will no
longer comply with U.S. andCanadian 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
the oxygen sensors and the three
way catalytic converter. These re- placements are not covered under
warranty.

Corrosion Protection

Two factors normally contribute to causing corrosion in your car:
1. Moisture trapped in body cavities. Dirt and road salt that collects in
hollows on the underside of the car stays damp, promoting
corrosion in that area.
2. Removal of paint and protective coatings from the exterior and
underside of the car. Many corrosion-preventive measures
are built into your Honda. You can
help keep your car from corroding
by performing some simple periodic
maintenance:

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 floor coverings for
dampness. Carpeting and floor
mats may remain damp for a long
time, especially in winter. This dampness can eventually cause
the floor panels to corrode. Use a high-pressure spray to clean
the underside of your car. This is
especially important in areas that
use road salt in winter. It is also a
good idea in humid climates and areas subject to salt air. Be careful
of the ABS wheel sensors and
wiring at each wheel.
Have the corrosion-preventivecoatings on the underside of your
car inspected and repaired
periodically.

Emission Controls

Exhaust Emission Controls

The exhaust emission controls include four systems: PGM-FI,
Ignition Timing Control, ExhaustGas Recirculation and Three Way
Catalytic Converter. These four
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
emission control systems are
separate from the crankcase and
evaporative emission control

systems.

PGM-FI System

The PGM-FI System uses sequential multiport fuel injection.It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
The Powertrain Control Module (PCM) uses various sensors to
determine how much air is going
into the engine. It then controls how
much fuel to inject under all operat-
ing conditions. Ignition Timing Control System
This system constantly adjusts the ignition timing, reducing the amountof HC, CO and NOx produced.
Exhaust Gas Recirculation (EGR)
System

The Exhaust Gas Recirculation (EGR) system takes some of the
exhaust gas and routes it back into
the intake manifold. Adding exhaust
gas to the air/fuel mixture reduces
the amount of NOx produced when
the fuel is burned.
Three Way Catalytic Converter
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 2), dinitrogen
(N 2), and water vapor. Replacement Parts

The emission control systems are designed and certified 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 newGenuine Honda replacement parts or
their equivalent for repairs. Using
lower quality parts may increase the emissions from your car.
The emissions control systems are covered by warranties separate from
the rest of your car. Read your
warranty manual for more informa-
tion.
