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.
The cooling system capacity is:
Start the engine and let it run f or
about 30 seconds. Then turn of f
the engine.
Fill the radiator with coolant up to
the base of the f iller neck.
Fill the reserve tank to the MAX
mark. Install the reserve tank cap.

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.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.
Remove the dipstick (yellow loop)
f rom the transmission and wipe it
with a clean cloth. Park the car on level ground. Shut
of f the engine.
Check the f luid level with the engine
at normal operating temperature.

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 (all models)
Clutch f luid reservoir
(manual transmission only)
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 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.
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.

T urning the steering wheel to f ull lef t
or right lock and holding it there can
damage the power steering pump.
Do not spill the power steering f luid
over the body, auto-tensioner, drive
belt and pulleys.
If spilled accidentally, wipe of f any
f luid completely.

To replace it:Loosen the f ive bolts.
Clean the air cleaner element by
blowing compressed air through it in
the opposite direction to normal air
f low. If you do not have access to
compressed air (such as a service
station), ask your Acura dealer to do
this service. The air cleaner element should be
cleaned or replaced according to the
time and distance recommendations
in the maintenance schedule.
Unsnap the clamp, then remove
the intake air duct f rom the f ront
of the air cleaner housing.
Use a pair of pliers to slide back
the clamp on the breather tube
attached to the side of the housing.
The air cleaner element is inside the
air cleaner housing on the driver’s
side of the engine compartment. Follow the replacement procedure
for removal and reinstallation.

Tighten the spark plugs caref ully. A
spark plug that is too loose can
overheat and damage the engine.
Overtightening can cause damage to
the threads in the cylinder head.

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.
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.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
.)
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.

The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.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.
