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
).
Cover the small hole in the center
of the cap with your f inger and
pull up until the tube is f ully
exposed.
Unf asten the reservoir cap.

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.

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.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
.)
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.
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.

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

Diagnosing why your engine won’t
start f alls into two areas, depending
on what you hear when you turn the
key to START (III):You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run. When you turn the ignition switch to
START (III), you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things:
Check the transmission interlock.
The clutch pedal must be pushed
all the way to the f loor or the
starter will not operate.
Turn the ignition switch to ON (II).
Turn on the headlights and check
their brightness. If the headlights
are very dim or don’t light at all,
the battery is discharged. See
on page .230

Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereisproba-
bly something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. (Seeon page .)
If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the car from
a booster battery (see page ). In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run.
Do you have f uel? Turn the
ignition switch to ON (II) for a
minute and watch the f uel gauge.
The low f uel level warning light
may not be working, so you were
not reminded to f ill the tank.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
Your car has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page ).
A key that is not properly coded
will cause the immobilizer system
indicator in the dash panel to blink
rapidly.
Are you using the proper starting
procedure? Ref er to
on page . If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See

To jump start your car, f ollow these
directions closely:
Open the hood and check the
physical condition of the battery
(see page ). In very cold
weather, check the condition of
the electrolyte. If it seems slushy
or like ice, do not try jump starting
until it thaws.
Turn of f all the electrical acces-
sories: heater, A/C, stereo system,
lights, etc.
Put the transmission in Neutral or
Park, and set the parking brake. Connect one jumper cable to the
positive ( ) terminal on your
Honda’s battery. Connect the
other end to the positive ( )
terminal on the booster battery.
If your car’s battery has run down,
you may be able to start the engine
by using a booster battery. Although
this seems like a simple procedure,
you should take several precautions.

230 A battery can explode if you do
not follow the correct procedure,
seriously injuring anyonenearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
If a battery sits in extreme cold, the
electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

µ
Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the grounding strap
as shown. Do not connect this
jumper cable to any other part of
the engine.The numbers in the illustration show
you the order to connect the jumper
cables. Make sure to disconnect the
cables in the reverse order.
Keep the ends of the jumper cables
away from each other and any metal
on the car until all are disconnected.
Otherwise, you may cause an
electrical short.Once your car is running, discon-
nectthenegativecablefromyour
car, then from the booster battery.
Disconnect the positive cable f rom
your car, then the booster battery.
Start your car. If the starter motor
still operates slowly, check the
jumper cable connections to make
sure they have good metal-to-
metal contact.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle.

If the temperature gauge stays at
the red mark, turn of f the engine.
Wait until you see no more signs
of steam or spray, then open thehood.
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank (see page). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks. If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
If there was no coolant in the
reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes
off.
Start the engine and set the
temperature control dial to
maximum. Add coolant to the
radiator up to the base of the f iller
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.
Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see
on page ). Put the radiator cap back on
tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair. (See
on page .)
