engine HONDA S2000 2009 2.G Owner's Manual

Help assure your vehicle’s f uture
reliability and perf ormance by paying
extra attention to how you drive
during the f irst 600 miles (1,000 km).
During this period:Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane number of 91 or higher.
Useof aloweroctanegasolinecan
cause occasional metallic knocking
noises in the engine and will result in
decreased engine perf ormance. Use
of a gasoline with a pump octane
number less than 87 can lead to
engine damage.
You should also f ollow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced. Avoidhardbrakingforthefirst
200 miles (300 km).
Do not change the oil until the
scheduled maintenance time.
Avoid full-throttle starts and rapid
acceleration. Do not exceed 5,500
rpm f or the f irst 600 miles (1,000
km) of operation.
For f urther important f uel-related
inf ormation, please ref er to your.
If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
Some gasoline today is blended with
oxygenates such as ethanol or
MTBE. Your vehicle is designed to
operate on oxygenated gasoline
containing up to 10% ethanol by
volume and up to 15% MTBE by
volume. Do not use gasoline
containing methanol.
Use of gasoline with these additives
may adversely af f ect perf ormance,
and cause the malfunction indicator
lamp on your instrument panel to
come on. If this happens, contact
your authorized dealer f or service.
In addition, in order to maintain good
perf ormance, f uel economy, and
emissions control, we strongly
recommend, in areas where it is
available, the use of gasoline that
does NOT contain manganese-based
f uel additives such as MMT.
We recommend quality gasoline
containing detergent additives that
help prevent f uel system and engine
deposits.

Open the f uel f ill door by pulling
on the knob on the driver’s door
jamb.
Park with the driver’s side closest
to the service station pump.even though the tank is not f ull,
there may be a problem with your
vehicle’s fuel vapor recovery
system. The system helps keep
f uel vapor f rom going into the
atmosphere. Try f illing at another
pump. If this does not f ix the
problem, consult your dealer.
Remove the f uel f ill cap slowly.
You may hear a hissing sound as
pressure inside the tank escapes.
Place the cap in the holder on the
fuel fill door.

Gasoline is highly flammable
and explosive. You can be
burned or seriously injured
when handling fuel.Stop the engine, and keep
heat, sparks, and flame away.
Handle fuel only outdoors.
Wipe up spills immediately.

Remove the dipstick again, and
check the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
see on page .
Wait a f ew minutes af ter turning the
engine of f bef ore you check the oil.
Remove the dipstick (black
handle).
Insert the dipstick all the way back
into its hole. Wipe of f the dipstick with a clean
cloth or paper towel.
To close the hood, lif t it up slightly to
remove the support rod f rom the
hole. Put the support rod back into
its holding clip. Lower the hood to
about a f oot (30 cm) above the
f ender, then let it drop. Make sure it
is securely latched. Holding the grip, pull the support
rod out of its clip. Insert the end
into the designated hole in the
hood.

Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, seeon page f or

The f ollowing f actors can lower your
vehicle’s f uel economy:
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
inf ormation display (see
on page ).
For example: Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.
Aerodynamic drag has a big ef f ect
on f uel mileage at speeds above 45
mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Idling
results in 0 miles per gallon.
An underinf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
It puts a heavier
load on the engine, increasing f uel
consumption.
In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy.

Fill the f uel tank until the nozzle automatically clicks of f .
Reset trip counter to zero.
Record the total gallons (liters) needed to ref ill.
Follow one of the simple calculations above.
The A/C
puts an extra load on the engine
which makes it use more f uel. Use
the f resh-air ventilation when
possible.
Combine several short trips into
one. A warmed-up engine is more
f uel ef f icient than a cold one.
Direct calculation is the
recommended source of inf ormation
about your actual f uel economy.
Using f requency of f ill-ups or taking
f uel gauge readings are NOT
accurate measures of f uel economy.

Apply the parking brake.
In cold weather, turn of f all
electrical accessories to reduce
the drain on the battery.
Push the clutch pedal down all the
way. The ENGINE START button
has no ef f ect unless the clutch
pedal is pressed.
Turn the ignition key to the ON
(II) position.
Without touching the accelerator
pedal, push the ENGINE START
button. Do not hold the ENGINE
START button for more than 15
seconds at a time. If the engine
does not start right away, pause
f or at least 10 seconds bef ore
trying again.If the engine fails to start, press
the accelerator pedal all the way
downandholdittherewhile
starting to clear flooding. If the
engine still does not start, return
to step 6.
If theenginedoesnotstartwithin

The engine is harder to start in cold
weather. Also, the thinner air f ound at
altitudes above 8,000 f eet (2,400
meters) adds to this problem.
T he immobilizer system protects your
vehicle f rom thef t. If an improperly-
coded key (or other device) is used, the
engine’s f uel system is disabled. For
more inf ormation, see page .

The manual transmission is
synchronized in all f orward gears f or
smooth operation. It has a lockout so
you cannot shift directly from fifth to
reverse instead of sixth (see page). When shif ting up or down,
make sure you push the clutch pedal
down all the way, shift to the next
gear, and let the pedal up gradually.
When you are not shif ting, do not
rest your f oot on the clutch pedal.
This can cause your clutch to wear
out f aster. When slowing down, you can get
extra braking f rom the engine by
shifting to a lower gear. This extra
braking can help you maintain a safe
speed and prevent your brakes f rom
overheating while going down a
steep hill. Bef ore downshif ting,
make sure the engine speed will not
go into the tachometer’s red zone in
the lower gear.
Your vehicle is equipped with an
aluminum shif t lever. If you leave the
vehicle parked outside f or a long
time on a hot day, be caref ul bef ore
moving the shift lever. Because of
the heat, the shift lever may be
extremely hot. If the outside
temperature is low, the shif t lever
f eels cold.
Come to a full stop before you shift
into reverse. You can damage the
transmission by trying to shift into
reverse with the vehicle moving.
Push down the clutch pedal, and
pause f or a f ew seconds bef ore
shif ting into reverse, or shif t into one
of the f orward gears f or a moment.
This stops the gears so they won’t
‘‘grind.’’

slippery surfaces. If you crash,
you can be injured.
Use extra care when driving on
