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
vehicle. You may use 5W-40 oil if the
temperature in your area goes below
0°F ( 20°C).
Your vehicle does not require any oil
additives. Additives may adversely
af f ect the engine or transmission
perf ormance and durability. 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 shown on the information
display.
Always change the oil and f ilter
according to the maintenance
messages shown on the inf ormation
display. The oil and f ilter collect
contaminants that can damage your
engine if they are not removed
regularly.
Run the engine until it reaches
normal operating temperature,
then shut it off.
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.

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,
causingthecoolingsystemto
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 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 and let it sit
f or several minutes, then check
the oil level on the dipstick. If
necessary, add more oil. Let the engine run f or several
minutes, then check the drain bolt
and oil f ilter f or leaks.
Always use Honda Long-Lif e
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 %
antif reeze and 50 % water. Never add
straight antif reeze or plain water.

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 the reserve tank is completely
empty, you should also check the
coolant level in the radiator.When the radiator and engine are
cool, relieve any pressure in the
cooling system by turning the
radiator cap counterclockwise,
without pressing down.
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.
Pourthecoolantslowlyand
caref ully so you do not spill any.
Clean up any spill immediately; it
could damage components in the
engine compartment.
Put the radiator cap on, and
tighten it fully.
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 vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components.

RADIATOR CAP
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 by looking at
the level gauge attached to the cap. 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.

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
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.If you are not sure how to check and
add f luid, contact your dealer. The transmission should be drained
and ref illed with new f luid according
to the intervals shown on the
inf ormation display. 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. Put a new washer on the f iller bolt,
then reinstall the f iller bolt and
tighten it securely.

In addition to proper inflation,
correct wheel alignment helps to
decrease tire wear. If you find a tire
is wo rn unevenly, have your dealer
check the wheel alignment.
Have your dealer check the tires if
you feel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed from the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comfort and tire life. For best results,
have the insta ller perform a dynamic
balance. You
should not rotate your vehicle’s
tires. The front and rear tires are
different sizes, so they cannot be
rotated front-to-rear. The original-
equipment tires on your vehicle have
a unidirectional tread pattern, so
th ey cannot be rotated side-to-side.
The tires that came on your vehicle
were designed and constructed to
provide superior grip during
acceleration, braking, and cornering.
As a trade-off, they will wear more
rapidly than tires used on ordinary
passenger vehicles. Because of the
vehicl e’s weight distribution, and the
fact that the rear wheels are the
driving wheels, you can expect them
to wear more rapidly than the front
tires. The
mileage you can expect from
yourvehicletiresisthesameas
comparable mid-and rear-engine
sports cars, and it will vary greatly
wi th your driving habits.
If you drive moderately, the rear
tires could last more than 10,000
miles (16,000 km). However, the
mileage will be substantially less if
you tend to drive your vehicle at the
upper limits of its capabilities.
You should caref ully inspect your
vehicle’s tires f or wear, damage, and
proper inf lation every 7,500 miles
(12,000 km) or when tire inspection
is indicated on the inf ormation
display (see page ). 142

If you need to park your vehicle f or
an extended period (more than 1
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.
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. If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f an cycles on and of f
twice). Pref erably, do this once a
month.
