Check the level in the windshield
washer reservoir at least monthly
duringnormaluse.Inbadweather,
when you use the washers of ten,
check the level every time you stop
f or f uel. This reservoir supplies the
windshield and rear window washers.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 fluid
on a clean cloth. This will help to
condition the blade edges.
The windshield washer reservoir is
located behind the lef t headlight.
Check the windshield washer f luid
level as f ollows:
Check the f luid level in the tube. If
the f luid level is low, f ill the
reservoir with windshield washer
f luid.
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 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.

The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If it is not, add
brake f luid to bring it up to that level.
Use the same fluid specified for the
brake system.
Low f luid level can indicate a leak in
the clutch system. Have this system
inspected as soon as possible.
The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected f or leaks or
worn brake pads.
Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement. However, the use of
any non-Honda brake fluid can cause
corrosion and decrease the lif e of the
system. Have the brake system
f lushed and ref illed with Honda
Heavy Duty Brake Fluid DOT 3 as
soon as possible.
Brake f luid marked DOT 5 is not
compatible with your car’s braking
system and can cause extensive
damage.
