2003 HONDA CIVIC HATCHBACK maintenance schedule

You may use a synthetic motor oil if
it meets the same requirements
given f or a conventional motor oil: it
displays the API Certif ication Seal,
and it is the proper weight as shown
on the chart. When using synthetic
oil, you must f ollow the oil and f ilter
change intervals given in the
maintenance schedule.Your Honda does not require any oil
additives. Additives may adversely
af f ect your engine’s or transmission’s
perf ormance and durability.
The oil’s viscosity or weight is
provided on the container’s label.
Select the oil f or your car according
to this chart.
5W-20 oil is f ormulated f or year-

Remove the oil f ilter and let the
remaining oil drain. A special
wrench (available from your
Honda dealer) is required to
remove the f ilter.
Install a new oil f ilter according to
instructions that come with it.
Open the hood and remove the
engine oil f ill cap. Remove the oil
drain bolt and washer f rom the
bottom of the engine. Drain the oil
into an appropriate container.
Run the engine until it reaches
normal operating temperature,
then shut it off.
Always change the oil and f ilter
accordingtothetimeanddistance
(miles/kilometers) recommenda-
tions in the maintenance schedule.
The oil and f ilter collect contami-
nants that can damage your engine if
they are not removed regularly.

Changing the oil and f ilter requires
special tools and access f rom
underneath the vehicle. The vehicle
should be raised on a service station-
type hydraulic lif t f or this service.
Unless you have the knowledge and
proper equipment, you should have
this maintenance done by a skilled
mechanic.

Turn the ignition ON (II). Turn
the temperature control dial to
maximum heat. Turn of f the
ignition. Open the hood. Make
sure the engine and radiator are
cool to the touch.

the maintenance schedule. Only use
Honda All Season Antif reeze/
Coolant Type 2.
Bef ore draining the coolant,
remove the cover under the
radiator.
Use a Phillips-head screwdriver to
remove the two bolts, and remove
the nine holding clips f rom the
cover (5 clips on the bottom and 4
clips on the side) with a f lat-tipped
screwdriver. Then pull the cover
away.
Draining the coolant requires access
to the underside of the vehicle.

Check the f luid level in the reser-
voirs monthly. There are up to two
reservoirs, depending on the model.
They are:Brake f luid reservoir
Clutch f luid reservoir
The brake f luid should be replaced
according to the time recommenda-
tion in the maintenance schedule.
Check the f luid level with the
transmission at normal operating
temperature and the vehicle sitting
on level ground. Remove the
transmission f iller bolt and caref ully
f eel inside the bolt hole with your
f inger. The f luid level should be up
to the edge of the bolt hole. If it is
not, add genuine Honda Manual
Transmission Fluid (MTF) until it
starts to run out of the hole. Reinstall
the f iller bolt and tighten it securely. If Honda MTF is not available, you
may use an SAE 10W-30 or 10W-40
viscosity motor oil with the API
Certif ication seal that says ‘‘FOR
GASOLINE ENGINES’’ as a
temporary replacement. However,
motor oil does not contain the proper
additives and continued use can
cause stiffer shifting. Replace as
soon as it is convenient.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule.

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.
Support the f ront and rear wiper
blade arms with a f olded towel or
ragsotheydonottouchthe

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.
Leave the parking brake off. Put
the transmission in Reverse. 158

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 .
