Ai
r Cleane r Elemen t

The air cleaner element should be cleaned or replaced according to the
time and distance recommendations in the maintenance schedule.
Cleanin g (Sever e Conditions )
Clean the air cleaner element by
blowing compressed air through it in
the opposite direction to normal air
flow. If you do not have access to compressed air (such as a servicestation), ask your Honda dealer to do
this service.
Follow the replacement procedure
for removal and reinstallation. Replacemen
t
The air cleaner element is inside the air cleaner housing on the passenger's
side of the engine compartment.
To replace it:
1. Unsnap the four hold-down clamps and remove the air cleaner
housing cover.
2. Remove the old air cleaner element. Carefully clean the inside of the
air cleaner housing with a damp
rag.
3. Place the new air cleaner element in the air cleaner housing.
4. Reinstall the air cleaner housing cover, snap the four hold-down
clamps back into place.

4. Examine the new wiper blades. If they have no plastic or metal rein-
forcement along the back edge,
remove the metal reinforcement strips from the old wiper blade and
install them in the slots along the edge of the new blade. 5. Slide the new wiper blade into the
holder until the tabs lock.
6. Slide the wiper blade assembly onto the wiper arm. Make sure it
locks in place.
7. Lower the wiper arm down against the windshield.Lower the passenger's side first,

r Conditionin g Syste m
Your car's air conditioning is a sealed system. Any major maintenance,
such as recharging, should be done
by a qualified mechanic. You can do a couple of things to make sure theair conditioning works efficiently.

Ai
r Conditionin g System , Ai r Conditionin g Filte r

Periodically check the engine's
radiator and air conditioning condenser for leaves, insects, and
dirt stuck to the front surface. These
block the air flow and reduce cooling efficiency. Use a light spray from a
hose or a soft brush to remove them.
The. condenser and radiator fins bend
easily. Only use a low-pressure spray
or soft-bristle brush to clean them.
Run the air conditioning at least once
a week during the cold weather
months. Run it for at least ten
minutes while you are driving at a steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the refrigerant. If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the

system with Refrigerant HFC-134a

(R-134a). (See Specifications on page
265.)

Whenever you have the air conditioning

system serviced, make sure the service

facility uses a refrigerant recycling
system. This system captures the
refrigerant for reuse. Releasing
refrigerant into the atmosphere can

damage the environment.
Ai
r Conditionin g Filte r
The air conditioning filter removes pollen and dust from the outside air
the climate control system brings
into the interior.
This filter should be replaced every 30,000 miles (48,000 km) under
normal conditions. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban areas that have high concentrations
of soot in the air from industry and
diesel-powered vehicles. Replace it
more often if air flow from the
heating and cooling system becomes
less than usual. Have the air conditioning filter replaced by your
Honda dealer.

Tire
s

To safely operate your car, your tires must be the proper type and size, in
good condition with adequate tread, and correctly inflated. The following
pages give more detailed information on how and when to check air
pressure, how to inspect your tires
for damage and wear, and what to do
when your tires need to be replaced. Inflatio
n
Keeping the tires properly inflated
provides the best combination of
handling, tread life and riding
comfort. Underinflated tires wear
unevenly, adversely affect handling
and fuel economy, and are more
likely to fail from being overheated. Overinflated tires can make your car
ride more harshly, are more prone to damage from road hazards, and wear

unevenly.

We recommend that you visually check your tires every day. If you
think a tire might be low, check it immediately with a tire gauge.
Use a gauge to measure the air
pressure at least once a month. Even
tires that are in good condition may
lose one to two psi (10 to 20 kPa, 0.1
to 0.2 kgf/cm2) per month. Remember to check the spare tire at
the same time you check all the other tires. Check the pressure in the tires when
they are cold. This means the car
has been parked for at least three
hours. If you have to drive the car
before checking the tire pressure,
the tires can still be considered "cold" if you drive less than 1 mile (1.6 km).
If you check the pressure when the
tires are hot (the car has been driven several miles), you will see readings
4 to 6 psi (30 to 40 kPa, 0.3 to 0.4
kgf/cm2) higher than the cold reading. This is normal. Do not letair out to match the specified cold
pressure. The tire will be underinflated.
You should get your own tire pressure gauge and use it whenever
you check your tire pressures. This
will make it easier for you to tell if a pressure loss is due to a tire problemand not due to a variation between

gauges.

Maintenance
CONTINUED

Using tires that are excessivel
y
worn or improperly inflated can
cause a crash in which you can be seriously hurt or killed.
Follow all instructions in this
owner's manual regarding tire inflation and maintenance.

Brak
e Syste m Indicato r

The Brake System indicator light comes on when you turn the ignitionON (II). If the parking brake is not
set, it goes off after you start the
engine. If the parking brake is set, it
goes off when you fully release the
parking brake with the engine running.
If it comes on at any other time, it
indicates a problem with the car's
brake system. In most cases, the
problem is a low fluid level in the brake fluid reservoir. Press lightly on
the brake pedal to see if it feels
normal. If it does, check the brake
fluid level the next time you stop at a service station (see page 193 ). If the
fluid level is low, take the car to your dealer and have the brake system
inspected for leaks or worn brake

pads.

However, if the brake pedal does not
feel normal, you should take
immediate action. Because of the
brake system's dual-circuit design, a
problem in one part of the system
will still give you braking at two wheels. You will feel the brake pedal
go down much farther before the car
begins to slow down, and you will
have to press harder on the pedal.
The distance needed to stop will be much longer.
Slow down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the longer distance needed to stop, it is
hazardous to drive the car. Youshould have it towed, and repaired as
soon as possible. (See Emergenc y
Towin g on page 258.)
If you must drive the car a short distance in this condition, drive
slowly and cautiously.

Emission
s Control s

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
form photochemical "smog." Carbon monoxide does not contribute tosmog creation, but it is a poisonous

gas.
Th
e Clea n Ai r Ac t
The United States Clean Air Act* sets standards for automobile
emissions. It also requires that
automobile manufacturers explain to owners how their emissions controls
work and what to do to maintain
them. This section summarizes how
the emissions controls work.
Scheduled maintenance is on page 172.
* In Canada, Honda vehicles comply
with the Canadian Motor Vehicle Safety Standards (CMVSS) for
Emissions valid at the time they are
manufactured.
Crankcas e Emission s Contro l
Syste m
Your car has a Positive Crankcase
Ventilation System. This keeps gasses that build up in the engine'scrankcase from going into the
atmosphere. The Positive Crankcase
Ventilation valve routes them from the crankcase back to the intake
manifold. They are then drawn into
the engine and burned.
Evaporativ e Emission s Contro l
Syste m
As gasoline evaporates in the fuel tank, an evaporative emissionscontrol canister filled with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is off. After
the engine is started and warmed up,
the vapor is drawn into the engineand burned during driving.
Onboar d Refuelin g Vapo r
Recover y
The Onboard Refueling Vapor Recovery (ORVR) system captures
the fuel vapors during refueling. The
vapors are adsorbed in a canister filled with activated carbon. While driving, the fuel vapors are drawn
into the engine and burned off.

Emission
s Control s

Exhaus t Emission s Control s
The exhaust emissions controls include four systems: PGM-FI,
Ignition Timing Control, Exhaust
Gas Recirculation and Three WayCatalytic 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 exhaustemissions control systems are
separate from the crankcase and
evaporative emissions 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 Engine Control Module (ECM) uses various sensors to determine
how much air is going into the engine. It then controls how much
fuel to inject under all operating conditions. Ignition Timing Control System
This system constantly adjusts the ignition timing, reducing the amount
of 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. Throughchemical reactions, it converts HC,
CO, and NOx in the engine's exhaust
to carbon dioxide (CO 2), dinitrogen
(N 2), and water vapor. Replacemen
t Part s
The emissions 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.
