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.
Turn of f the engine, let it sit f or
several minutes, then check the oil
level on the dipstick. If necessary,
add more oil.

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.

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.Make sure the engine and radiator
are cool.
Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
pressing down.

Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.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.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather. The low washer
level indicator comes on when the
level is low (see page ).
Check the f luid level by removing
the cap and looking at the level
gauge. 61

Do 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.

Check the f luid level with the engine
at normal operating temperature.Park the vehicle on level ground.
Shut of f the engine.
Remove the dipstick (yellow loop)
f rom the transmission, and wipe it
with a clean cloth. Insert the dipstick all the way into
the transmission securely as
shown in the illustration.If the level is below the lower
mark, add f luid into the dipstick
hole to bring it to the upper mark.
Pour the f luid slowly and caref ully
so you do not spill any. Clean up
any spill immediately; it could
damage components in the engine
compartment.
Always use Honda ATF-Z1
(automatic transmission f luid). If
it’s not available, you may use a
DEXRONIII automatic
transmission f luid as a temporary
replacement. However, continued
use can af f ect the shif t quality.
Have the transmission f lushed and
ref illed with Honda ATF-Z1 by
your dealer as soon as it is
convenient.
Remove the dipstick, and check
the f luid level. It should be
between the upper and lower
marks.

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 stif f er shif ting. Replace as
soon as it is convenient.
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 Honda Manual
Transmission Fluid (MTF) until it
starts to run out of the hole. Reinstall
the f iller bolt, and tighten it securely.
Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
The automatic transmission should
be drained and ref illed with new f luid
when this service is indicated by a
maintenance message on the
inf ormation display.
If you are not sure how to add f luid,
contact your dealer. 6.

Check the level on the side of the
reservoir when the engine is cold.
The f luid should be between the
UPPER LEVEL and LOWER LEVEL.
If not add power steering f luid to the
UPPER LEVEL mark.
Pour the f luid slowly and caref ully so
you do not spill any. Clean up any
spill immediately; it could damage
components in the enginecompartment.
Always use Honda Power Steering
Fluid. You may use another power
steering f luid as an emergency
replacement, but have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
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.
The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If it is not, add
brake f luid to bring it up to that level.
Use the same fluid specified for the
brake system.
A low f luid level can indicate a leak
in the clutch system. Have this
system inspected as soon as possible.

When you turn the ignition switch to
the START (III) position, 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.
Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:
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.
Store the jack and tools in the tool
kit case. Place the tool kit case in
the center of the flat tire.
Store the wheel cover or center
cap in the trunk. Make sure it does
not get scratched or damaged.
Lower the trunk f loor, then close
the trunk lid.
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
on page .259

Do you have f uel? Check the f uel
gauge; the low f uel indicator may
not be working.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See on page .
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 ).
Are you using the proper starting
procedure? Ref er to
on page .
In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to the START (III)
position, but the engine does not run.
Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the f uses. If the f uses
areOK,thereisprobably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem (see
on 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 vehicle
f rom a booster battery (see page ). 272
