2003 HONDA CIVIC HATCHBACK maintenance

Periodically check the engine’s
radiator and air conditioning
condenser f or leaves, insects, and
dirt stuck to the f ront surf ace. These
block the air f low and reduce cooling
ef f iciency. Use a light spray f rom a
hose or a sof t brush to remove them.If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Ref rigerant HFC-134a
(R-134a). (See Specif ications on page
.)
Run the air conditioning at least once
a week during the cold weather
months. Run it f or 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 ref rigerant.
Your car’s air conditioning is a sealed
system. Any major maintenance,
such as recharging, should be done
by a qualif ied mechanic. You can do
a couple of things to make sure the
air conditioning works ef f iciently.

AIR CONDITIONING

Whenever you have the air conditioning
system serviced, make sure the service
f acility uses a ref rigerant recycling
system. This system captures the
ref rigerant f or reuse. Releasing
ref rigerant into the atmosphere can
damage the environment.
The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.

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.
To saf ely operate your car, your tires
must be the proper type and size, in
good condition with adequate tread,
and correctly inf lated. The f ollowing
pages give more detailed inf ormation
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.
Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort. Underinf lated tires wear
unevenly, adversely af f ect handling
and f uel economy, and are more
likely to f ail f rom being overheated.
Overinf lated tires can make your car
ride more harshly, are more prone to
damage f rom road hazards, and wear
unevenly.Check the pressure in the tires when
they are cold. This means the car
has been parked f or at least three
hours. If you have to drive the car
bef ore 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 /cm ) higher than the cold
reading. This is normal. Do not let
air out to match the specified cold
pressure. The tire will be
underinf lated.
Use a gauge to measure the air
pressure at least once a month. Even
tires that are in good condition may
lose 1 to 2 psi (10 to 20 kPa, 0.1 to 0.2
kgf /cm ) per month. Remember to
checkthesparetireatthesametime
you check all the other tires.

Using tires that are excessively
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.

Every time you check inf lation, you
should also examine the tires f or
damage, f oreign objects, and wear.
Youshouldlookfor:Bumps or bulges in the tread or
side of the tire. Replace the tire if
youfindeitherof theseconditions.
Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see f abric or cord.
Excessive tread wear. In addition to proper inf lation,
correct wheel alignment helps to
decrease tire wear. If you f ind a tire
is worn unevenly, have your dealer
check the wheel alignment.
The tires were properly balanced by
the factory. They may need to be
rebalanced at some time bef ore they
are worn out. Have your dealer
check the tires if you f eel a consis-
tent vibration while driving. A tire
should always be rebalanced if it is
removed f rom the wheel f or repair.
Your car’s tires have wear indicators
molded into the tread. When the
tread wears down to that point, you
will see a 1/2 inch (12.7 mm) wide
band running across the tread. This
shows there is less than 1/16 inch
(1.6 mm) of tread lef t on the tire. A
tire that is this worn gives very little
traction on wet roads. You should
replace the tire if you can see the
tread wear indicator in three or more
places around the tire. Make sure the installer balances the
wheels when you have new tires
installed. This increases riding
comf ort and tire lif e. Your car’s
original tires were dynamic or ‘‘spin’’
balanced at the f actory. For best
results, have the installer perf orm a
dynamic balance.

If you need to park your car f or an
extended period (more than one
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your car back on the road. If
possible, store your car indoors.
If the car is to be stored for a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the car is being stored indoors).Coverthecarwitha‘‘breathable’’
cover, one made f rom a porous
material such as cotton.
Nonporous materials, such as
plastic sheeting, trap moisture,
which can damage the paint.
Disconnect the battery.

To minimize sticking, apply a
silicone spray lubricant to all door
and hatch seals. Also, apply a body
wax to the painted surf aces that
mate with the door and hatch seals. If possible, run the engine f or a
while periodically (pref erably once
amonth).
If you store your car f or 12 months
or longer, have your Honda dealer
perf orm the inspections called f or in
the 24 months/30,000 miles (48,000
km) maintenance schedule (Normal
Conditions) as soon as you take it
out of storage (see page ). The
replacements called f or in the
maintenance schedule are not
needed unless the car has actually
reached that time or mileage.

If you want to use an air f reshener/
deodorizer in the interior of your car,
it is best to use a solid type. Some
liquid air f resheners contain chemi-
cals that may cause parts of the
interior trim and f abric to crack or
discolor.
If you use a liquid air f reshener,
make sure you f asten it securely so it
does not spill as you drive.Two f actors normally contribute to
causing corrosion in your car:
Moisture trapped in body cavities.
Dirtandroadsaltthatcollectsin
hollows on the underside of the
car stays damp, promoting
corrosion in that area.
Removal of paint and protective
coatings f rom the exterior and
underside of the car.
Many corrosion-preventive measures
are built into your Honda. You can
help keep your car f rom corroding
by perf orming 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 f loor coverings f or
dampness. Carpeting and f loor
mats may remain damp f or a long
time, especially in winter. This
dampness can eventually cause
the f loor panels to corrode.
Use a high-pressure spray to clean
the underside of your car. This is
especially important in areas that
useroadsaltinwinter.Itisalsoa
good idea in humid climates and
areas subject to salt air.
Have the corrosion-preventive
coatings on the underside of your
car inspected and repaired
periodically.

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.

Saf ety Standards (CMVSS) f or

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 .
