To add oil, unscrew and remove the
engine oil f ill cap on top of the valve
cover. Pour in the oil, and install the
engine oil f ill cap. Tighten it securely.
Wait a f ew minutes and recheck the
oil level. Do not f ill above the upper
mark; you could damage the engine.Oil is a major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade 5W-20
detergent oil displaying the API
Certif ication Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute’s latest requirements.
Make sure the API Certif ication Seal
says ‘‘For Gasoline Engines.’’
Pour the oil slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment. Honda Motor Oil is the pref erred
5W-20 lubricant f or your car. It is

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.
The coolant you add should always
be a mixture of 50 percent antif reeze
and 50 percent water. Never add
straight antif reeze or plain water.If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
Make sure the engine and radiator
are cool.
Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water. It
does not require any additional
mixing.
If it is not available, you may use
another major-brand non-silicate
coolant as a temporary replacement.
Make sure it is a high-quality coolant
recommended f or aluminum engines.
However, 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.

Check the level in the windshield
washer reservoir at least monthly
during normal usage. In bad weather,
when you use the washers of ten,
check the level every time you stop
for fuel.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 the blade edges.
The windshield washer reservoir is
located behind the driver’s side
headlight. Check the reservoir’s f luid
level by removing the cap and
looking at the level gauge attached
to the cap. Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
The low washer level indicator will
light when the level is low (see page
).

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

Check the f luid level with the engine
at normal operating temperature.Remove the dipstick (yellow loop)
f rom the transmission and wipe it
with a clean cloth.
Insert the dipstick all the way into
the transmission securely as
shown in the illustration.Remove the dipstick and check
the f luid level. It should be
between the upper and lower
marks.
Park the car on level ground. Shut
of f the engine. For accurate
results, wait at least 60 seconds,
andnomorethan90seconds,

Check the f luid level in the reser-
voirs monthly. There are up to two
reservoirs, depending on the model.
They are:
The brake f luid should be replaced
accordingtothetimeanddistance
recommendations in the mainte-
nance schedule.Brake f luid reservoir (all models)
Clutch f luid reservoir
(manual transmission only)
Check the f luid level with the
transmission at normal operating
temperature and the car 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 Honda Manual Transmis-
sion 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.

A low power steering f luid level can
indicate a leak in the system. Check
the f luid level f requently and have
the system inspected as soon as
possible.
Always use Honda Power Steering
Fluid. If it is not available, you may
use another power steering f luid as
an emergency replacement.
However, continued use can cause
increased wear and poor steering in
cold weather. Have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
You should check the f luid level in
the power steering reservoir at least
once a year. Check the level when
the engine is cold. Look at the side
of the reservoir. The f luid should be
between the UPPER LEVEL and
LOWER LEVEL. If it is below the
LOWER LEVEL, add power steering
f luid to the UPPER LEVEL.
