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 .Lights Check the operation of
the headlights, parking lights,
taillights, high-mount brake light,
turn signals, brake lights, and
license plate lights monthly. See
page . Tires Check the tire pressure
monthly. Examine the tread f or
wear and foreign objects. See page
.
Automatic transmission Check
the f luid level monthly. See page .
Brakes Check the f luid level
monthly. See page . When adding or replacing f luids
within the engine compartment, such
as oil and coolant, be caref ul of
spillage.
This may lead to damage parts in the
engine compartment.

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.
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.

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.

CONT INUED
Turn the radiator cap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
cooling system. Make sure the engine and radiator
are cool.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.
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.

Remove the reserve tank f rom its
holder by pulling it straight up.
Drain the coolant, then put the
tank back in its holder.
When the coolant stops draining,
tightenthedrainplugatthe
bottom of the radiator.
Turn the ignition ON (II). Turn
the heater temperature control
dial to maximum heat (climate
control to 90°F/32°C). Turn of f
the ignition. Open the hood. Make
sure the engine and radiator are
cool to the touch.
Remove the radiator cap. Loosen the drain plug on the
bottom of the radiator. The
coolant will drain through the
splash guard.
Install a rubber hose on the drain
bolt at the rear of the engine
cylinder block. Loosen the drain
bolt.

Check the coolant level in the
radiator and add coolant if needed. 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 let it run until
the radiator cooling f an comes on
at least twice. Then stop the
engine. 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.
The windshield washer reservoir is
located behind the passenger’s side
headlight.

The pointer of your car’s tempera-
ture gauge should stay in the mid-
range under most conditions. It may
go higher if you are driving up a long
steep hill on a very hot day. If it
climbs to the red mark, you should
determine the reason.Your car can overheat f or several
reasons, such as lack of coolant or a
mechanical problem. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the car or
engine cover. In either case, you
should take immediate action. Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn of f the climate control and all
otheraccessories.Turnonthe
hazard warning indicators.
If you see steam and/or spray
coming f rom under the hood, turn
of f the engine.
If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading
(climbing a long, steep hill on a
hot day with the A/C running, for
example), the engine should start
to cool down almost immediately.
If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving.

T aking Care of t he Unexpect ed299
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
pointer at the red mark can cause
serious damage to your engine.
