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.
Never add straight antifreeze or
plain water.
If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
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.If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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.

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.

Check the f luid level in the
windshield washer reservoir at least
monthly during normal use. This
reservoir supplies the windshield and
rear window washers.
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 them.
Windshield Washers
Maint enance139
NOTICE:LEVEL GAUGEDo not use engine antif reeze
or a vinegar/water solution in the
windshield washer reservoir. Antif reeze
can damage your vehicle’s paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer f luid.

Park the vehicle on level ground.
With the A/C of f , let the engine
run until the radiator cooling f an
cycles on and of f twice. Then turn
of f the engine.
NOTE: For accurate results, wait at
least 60 seconds, and no more than
90 seconds, af ter turning of f the
engine to check the f luid level. Remove the dipstick (yellow loop)
f rom the transmission, and wipe it
with a clean cloth.
Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
Remove the dipstick and check
the f luid level. It should be
between the upper and lower
marks within the HOT range.
If the level is below the lower
mark, add f luid into the f iller hole
to bring it to the upper mark.
Pour the f luid slowly and caref ully
so you do not spill. Clean up any
spills immediately; it could damage
components in the engine
compartment.
Always use Honda ATF-Z1
(Automatic Transmission Fluid). If
it’s not available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can af f ect the shif t quality.
Have the transmission flushed and
ref illed with Honda ATF-Z1 as
soon as it is convenient.

To thoroughly f lush the transmission,
the technician should drain and ref ill
it with Honda ATF-Z1, then drive the
vehicle f or a short distance. Do this
three times. Then drain and ref ill the
transmission a f inal time.Insert the dipstick all the way back
into the transmission securely as
shown in the illustration. If you
added f luid, return to step 1 to
recheck the f luid level.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule.
If you are not sure how to add f luid,
contact your Honda dealer. Check the f luid level with the
transmission at normal operating
temperature and the vehicle sitting
on the level ground.
Remove the black cover under the

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.
Using any non-Honda brake f luid 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.
Pour the f luid slowly and caref ully so
you do not spill. Clean up any spills
immediately; it could damage
components in the engine
compartment.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage.
Check the f luid level in the
reservoirs 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)
Replace the brake f luid according to
the recommendation in the
maintenance schedule.
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.
If you are not sure how to check and
add f luid, contact your Honda dealer.

Diagnosing why the 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.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. With an
automatic transmission, it must be
in Park or Neutral.
Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page ). 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 .
Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
the f uses are OK, there is
probably something wrong with
the electrical circuit f or the
ignition switch or starter motor.
You will need a qualif ied
technician to determine the
problem (see
on page ).
