Quality grades can be f ound where
applicable on the tire sidewall
between the tread shoulder and the
maximum section width. For
example:
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades. The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices, and dif f erences in
road characteristics and climate.
The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.

The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled
conditions on a specif ied indoor
laboratory test wheel. Sustained high
temperature can cause the material
of the tire to degenerate and reduce
tire life, and excessive temperature
can lead to sudden tire f ailure. The
grade C corresponds to a level of
perf ormance which all passenger car
tires must meet under the Federal
Motor Vehicle Saf ety Standard No.
109. Grades B and A represent
higher levels of perf ormance on the
laboratory test wheel than the
minimum required by law. Warning: The temperature grade f or
this tire is established f or a tire that
is properly inf lated and not over-
loaded. Excessive speed, underinf la-
tion, or excessive loading, either
separately or in combination, can
cause heat buildup and possible tire
f ailure.

The burning of gasoline in your
vehicle’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx), and hydrocarbons (HC).
Gasoline evaporating f rom 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.
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 vehicle has a positive
crankcase ventilation system. This
keeps gasses that build up in the
engine’s crankcase f rom 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.
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 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
.
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 f our systems: PGM-FI,
ignition timing control, secondary air
injection system, 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 PGM-FI System uses sequential
multiport f uel injection.
It has three subsystems: air intake,
engine control, and f uel 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.During engine warm-up, air is
pumped into the exhaust to reduce
emissions when the engine is cold.
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.
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
Honda replacement parts or their
equivalent f or repairs. Using lower
quality parts may increase the
emissions f rom your vehicle.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more inf orma-
tion.
