There are three popular types of
prof essional towing equipment.
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.
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.
The operator
loads your car on the back of a truck.
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 is equipped with a f ront
spoiler, remove it bef ore towing so it
is not damaged.

Improper towing preparation will
damage the transmission. Follow the
above procedure exactly. If you cannot
shif t the transmission or start the
engine, 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.

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 Motor Vehicle
Saf ety Standards (CMVSS) f or
Emissions valid at the time they are
manuf actured.
The 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.
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 fromthe crankcase back to the intake
manif old. They are then drawn into
the engine and burned.
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 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 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 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)
uses various sensors to determine
how much air is going into the
engine. It then controls how much
f uel to inject under all operating
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 ), dinitrogen
(N ), and water vapor. 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.

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.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.Keep the engine tuned-up.
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. Have your car diagnosed and
repaired if it is misf iring, back-
f iring, stalling, or otherwise not
running properly.

Make sure the gas tank is nearly,
but not completely, f ull (around
3/4).
Make sure the ambient
temperature is between 20° and
95°F.Without touching the accelerator
pedal, start the engine and let it
idle f or 20 seconds.
If you take your car for a state
emissions test shortly af ter the
battery has been disconnected or
gone dead, it may not pass the test.
This is because of certain ‘‘readiness
codes’’ that must be set in the on-
board diagnostics f or the emissions
systems. These codes are erased
when the battery is disconnected,
and set again only after several days
of driving under a variety of
conditions. If the testing f acility determines that
the readiness codes are not set, you
will be requested to return at a later
date to complete the test. If you must
get the car re-tested within the next
two or three days, you can condition
the car for re-testing by doing the
f ollowing.
Keep the car on Neutral.
Increase the engine speed to
2,000 rpm and hold it there until
the temperature gauge rises to at
least 1/4 of the scale
(approximately 3 minutes).
Make sure the car has been
parked with the engine of f f or 8
hours or more.
