There are three popular types of
prof essional towing equipment.
The operator
loads your car on the back of a truck.
The tow
truck uses two pivoting arms that go
under the tires (f ront or rear) and lif t
them of f the ground. The other two
tires remain on the ground. The tow
truck uses metal cables with hooks
on the ends. These hooks go around
parts of the f rame or suspension and
the cables lif t that end of the car of f
the ground. Your car’s suspension
and body can be seriously damaged.
If your Honda cannot be transported
by f lat-bed, it should be towed by
wheel-lif t equipment with the f ront
wheels of f the ground. If due to
damage, your car must be towed
with the f ront wheels on the ground,
do the f ollowing:
Release the parking brake.
Shif t the transmission to Neutral. With the f ront wheels on the ground,
it is best to tow the car no farther
than 50 miles (80 km), and keep the
speedbelow35mph(55km/h).
If your car needs to be towed, call a
prof essional towing service or, if you
belong to one, an organization that
provides roadside assistance. Never
tow your car behind another vehicle
with just a rope or chain. It is very
dangerous.
Release the parking brake.
Start the engine.

Improper towing preparation will
damage the transmission. Follow the
above procedure exactly. If you cannot
shif t the transmission or start the
engine (automatic transmission), your
car must be transported with the f ront
wheels of f the ground.

Your car has several identif ying
numbers located in various places.
The Vehicle Identif ication Number
(VIN) is the 17-digit number your
Honda dealer uses to register your
car f or warranty purposes. It is also
necessary f or licensing and insuring
your car. The easiest place to find
the VIN is on a plate fastened to the
top of the dashboard. You can see it
by looking through the windshield
on the driver’s side. It is also on the
Certification label attached to the
driver’s doorjamb, and is stamped on
the engine compartment bulkhead.
The VIN is also provided in bar code
on the Certification label.

ÎThe burning of gasoline in your car’s
engine produces several byproducts.
Some of these are carbon monoxide
(CO), oxides of nitrogen (NOx) and
hydrocarbons (HC). Gasoline
evaporating from the tank also
produces hydrocarbons. Controlling
the production of NOx, CO, and HC
is important to the environment.
Under certain conditions of sunlight
and climate, NOx and HC react to
f orm photochemical ‘‘smog.’’ Carbon
monoxide does not contribute to
smog creation, but it is a poisonous
gas. The United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
Scheduled maintenance is on page
.
In Canada, Honda vehicles comply
with the Canadian emission
requirements, as specif ied in an
agreement with Environment
Canada, at the time they are
manuf actured.
Your car has a Positive Crankcase
Ventilation System. This keeps
gasses that build up in the engine’s
crankcase from going into the
atmosphere. The Positive Crankcase Ventilation valve routes them from
the crankcase back to the intake
manif old. They are then drawn into
the engine and burned.
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 .
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.

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
lowerqualitypartsmayincreasethe
emissions f rom your car.
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 exhaust emissions controls
include f our systems: PGM-FI,
Ignition Timing Control, Exhaust
Gas 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
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems. The Exhaust Gas Recirculation
(EGR) system takes some of the
exhaust gas and routes it back into
the intake manif old. Adding exhaust
gas to the air/f uel mixture reduces
the amount of NOx produced when
the f uel is burned.
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.

Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the three
way catalytic converter inef f ective.
The three way catalytic converter
contains precious metals that serve
as catalysts, promoting chemical
reactions to convert the exhaust
gasses without af f ecting the metals.
The catalytic converter is ref erred to
as a three-way catalyst, since it acts
on HC, CO, and NOx. A replacement
unit must be an original Honda part
or its equivalent.
The three way catalytic converter
must operate at a high temperature
for the chemical reactions to take
place. It can set on f ire any com-
bustible materials that come near it.
Park your car away f rom high grass,
dry leaves, or other f lammables.
A defective three way catalytic
converter contributes to air pollution,
and can impair your engine’s per-
f ormance. Follow these guidelines to
protect your car’s three way catalytic
converter. Keep the engine tuned-up.
Have your car diagnosed and
repaired if it is misf iring, back-
f iring, stalling, or otherwise not
running properly.
