Youshouldcheckthefollowing
items at the specif ied intervals. If
you are unsure of how to perf orm
any check, turn to the page given.
Engine oil level Check every
time you fill the fuel tank. See
page .
Engine coolant level Check the
radiator reserve tank every time
you f ill the f uel tank. See page .
Windshield washer f luid Check
the level in the reservoir monthly.
If weather conditions cause you to
use the washers f requently, check
the reservoir each time you stop
f or f uel. See page .Tires Check the tire pressure
monthly. Examine the tread f or
wear and foreign objects. See page
.
Brakes Check the f luid level
monthly. See page . Automatic transmission Check
the f luid level monthly. See pages and . Lights Check the operation of
the headlights, parking lights,
taillights, high-mount brake light,
turn signals, brake lights, and
license plate light monthly. See

Refill the engine with the recom-
mended oil.
Engine oil change capacity
(including f ilter):Let the engine run f or several
minutes, then check the drain bolt
and oil f ilter f or leaks.
Turn of f the engine, let it sit f or
several minutes, then check the oil
level. If necessary, add oil to bring
the level to the upper mark on the
dipstick. Replace the engine oil f ill cap.
Start the engine. The oil pressure
indicator light should go out within
f ive seconds. If it does not, turn of f
the engine and reinspect your
work.
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.

) 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.

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 incorrosion, 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 reserve tank is completely
empty, you should also check the
coolant level in the radiator.
Make sure the engine and radiator
are cool.
Turn the radiator cap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
cooling system.
Remove the radiator cap by
pushing down and turning
counterclockwise.

4-cylinder modelsRemoving 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.

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
spills immediately. Spilled coolant
could damage components in the
engine compartment. Put the radiator cap back on.
Tighten it f ully. 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 car’s cooling
system. They may not be compatible
with the coolant or engine compo-
nents.

Thecoolingsystemshouldbe
completely drained and ref illed with
new coolant according to the time
and distance recommendations in
the maintenance schedule. Only use
Honda All Season Antif reeze/
Coolant Type 2. Use of any non-
Honda coolant or plain water can
result in corrosion and deposits in
the cooling system.
Draining the coolant requires access
to the underside of the car. Unless
you have the tools and knowledge,
you should have this maintenance
done by a skilled mechanic.Openthehood.Makesurethe
engine and radiator are cool to the

Turn the ignition ON (II). Turn
the temperature control dial all the

The cooling system capacity is:Start the engine and let it run for
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.
Install the radiator cap, and
tighten it to the first stop.
Start the engine and let it run until
the radiator cooling f an comes on
at least twice. Then stop the
engine.
Remove the radiator cap. Pour
coolant into the radiator up to the
base of the f iller neck and into the
reserve tank up to the MAX mark. Start the engine and hold it at
1,500 rpm until the cooling f an
comes on. Turn of f the engine.
Check the coolant level in the
radiator and add coolant if needed.
Install the radiator cap, and
tighten it fully.
If necessary, f ill the reserve tank
to the MAX mark. Install the
reserve tank cap.
