2004 HONDA CIVIC HYBRID engine

Run the engine until it reaches
normal operating temperature,
then shut it off.
Always change the oil and f ilter
according to the recommendations in
the maintenance schedule. The oil
and f ilter collect contaminants 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.
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. You must
f ollow the oil and f ilter change
intervals given on 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.
Open the hood and remove the
engine oil f ill cap.
Remove the nine holding clips
with a flat-tipped screwdriver, then
pull the under-cover down.

If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.
If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system f or leaks.
Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water.
Never add straight antifreeze or
plain water.
Turn of f the engine, let it sit f or
several minutes, then check the oil
level on the dipstick. If necessary,
add more oil.

NOTICE:
RESERVE TANK
Improper disposal of engine
oil can be harmf ul to the environment.
If you change your own oil, please
dispose of the used oil properly. Put it
in a sealed container and take it to a
recycling center. Do not discard it in a
trash bin or dump it on the ground.

If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.When the radiator and engine are
cool, relieve any pressure in the
cooling system by turning the
radiator cap counterclockwise,
without pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pour the coolant slowly and
caref ully so you do not spill. Clean
up any spill immediately; it could
damage components in the engine
compartment.
Put the radiator cap back on and
tighten it.
Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components.

RADIATOR CAP
Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.

Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.The low washer
level indicator will light when the
level is low.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition them.

NOTICE: Do not use engine antif reeze
or a vinegar/water solution in the
windshield washer reservoir. Antif reeze
can damage your vehicle’s paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer f luid.

Always use Honda ATF-Z1
(Automatic Transmission Fluid). If
it’s not available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can af f ect the shif t quality.
Have the transmission flushed and
ref illed with Honda ATF-Z1 as
soon as it is convenient.
Insert the dipstick all the way back
in the transmission.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule. To thoroughly f lush the
transmission, the technician
should drain and ref ill it with
Honda ATF-Z1, then drive the
vehicle f or a short distance. Do
this three times. Then drain and
ref ill the transmission a f inal time.
Remove the dipstick (yellow loop)
f rom the transmission, and wipe it
with a clean cloth.
Check the f luid level with the engine
at normal operating temperature.
Remove the dipstick and check
the f luid level. It should be
between the upper and lower
marks within the HOT range.
Park the vehicle on level ground.
Shut of f the engine.
Insert the dipstick all the way into
the transmission securely. If the level is below the lower
mark, add f luid into the f iller hole
to bring it to the level between the
upperandlowermarks.

Check the f luid level with the

temperature and the vehicle sitting
on level ground. Remove the under-
cover to access the transmission
housing(seepage ).Removethe
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 Honda Manual Transmis-
sion Fluid (MTF) until it starts torun 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.
