The oil’s viscosity or weight is
provided on the container’s label.
Select the oil f or your vehicle
according to this chart.
An oil with a viscosity of 10W-30 is
pref erred f or optimum f uel economy
and year-round protection in your
Honda. You may use a 5W-40 oil if
the temperature in your area goes
below 0°F ( 20°C).
You may use a synthetic motor oil if
it meets the same requirements
given f or a conventional motor oil: it
displays the API Certif ication Seal
and it is the proper weight. You must
f ollow the oil and f ilter change
intervals given on the maintenance
schedule.
Your Honda does not require any oil
additives. Additives may adversely
af f ect your engine’s or transmission’s
perf ormance and durability.
Always change the oil and f ilter
according to the recommendations in
the maintenance schedule. The oil
and f ilter collect contaminants that
can damage your engine if they are
not removed regularly.
Changing the oil and f ilter requires
special tools and access f rom
underneath the vehicle. The vehicle
should be raised on a service station-
type hydraulic lif t f or this service.
Unless you have the knowledge and
proper equipment, you should have
this maintenance done by a skilled
mechanic.
Run the engine until it reaches
normal operating temperature,
then shut it off.

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.Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.
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.
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. Install
the f iller bolt, and tighten it securely.

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.

If you need to park your vehicle f or
an extended period (more than one
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors.Fill the f uel tank.
Change the engine oil and f ilter.
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc., are
completely dry.
Raise the convertible top cover.
Leave the parking brake off. Put
the transmission in Reverse. Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).
Disconnect the battery.
Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month.
If you store your vehicle f or 1 year or
longer, have your Honda dealer
perf orm the inspections called f or in
the 2 years/30,000 miles (48,000 km)
maintenance schedule (Normal
Conditions) as soon as you take it
out of storage (see page ). The
replacements called f or in the
maintenance schedule are not
needed unless the vehicle has
actually reached that time or mileage.
Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and trunk seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and trunk seals.

Drive slowly along the shoulder until
you get to an exit or an area that is

remove the f ront tire on that same

tire on the rear.
Park the vehicle on f irm, level, and
non-slippery ground. Put the

Turn on the hazard warning lights,
and turn the ignition switch to

JACK
The vehicle can easily roll off
the jack, seriously injuring
anyone underneath.
Follow the directions for
changing a tire exactly, and
never get under the vehicle
when it is supported only by the
jack. Use the jack that came with
your vehicle. If you try to raise another
vehicle with this jack or use another
jack to raise your vehicle, the vehicle or
jack can be damaged.

Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you press
the ENGINE START button.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 press the ENGINE
START button, 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.
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 .
Press the ENGINE START button,
then release it. 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 .)
Check these things:
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 ). Check the transmission interlock.
The clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. 52 162

Although this seems like a simple
procedure, you should take several
precautions.
Open the hood, and check the
physical condition of the battery.
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.
Connect one jumper cable to the
positive ( ) terminal on your
battery. Connect the other end to
the positive ( ) terminal on the
booster battery. 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.
Turn of f all the electrical
accessories: heater, A/C, audio
system, lights, etc. Put the
transmission in Neutral, and set
the parking brake.

To Jump Start Your Vehicle:

NOTICE:
A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
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.

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 (seeon page ).
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark. If the temperature gauge stays at
the red mark, 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,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving. If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood. Saf ely pull to the side of the road.
Put the transmission in Neutral,
and set the parking brake. Turn
of f the all accessories, and turn on
the hazard warning indicators.
