need to be broken-in by moderate
use f or the f irst 200 miles (300
km). Your Acura is designed to operate on
premium unleaded gasoline with a
pump octane number of 91 or higher.
In Canada, some gasolines contain
an octane-enhancing additive called
MMT. If you use such gasolines,
your emissions control system
perf ormance may deteriorate and
the Malf unction Indicator Lamp on
your instrument panel may turn on.
If this happens, contact your
authorized Acura dealer f or service.
Help assure your car’s f uture
reliability and perf ormance by paying
extra attention to how you drive
during the f irst 600 miles (1,000 km).
Useof aloweroctanegasolinecan
cause occasional metallic knocking
noises in the engine and will result in
decreased engine perf ormance.
We recommend gasolines containing
detergent additives that help prevent
f uel system and engine deposits.
Using gasoline containing lead will
damage your car’s emissions
controls. This contributes to air
pollution.
Do not change the oil until the
recommended time or mileage
intervalshowninthemaintenance
schedule.

Open the f uel f ill door by pulling

driver’s seat.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.
Stop f illing the tank af ter the f uel
nozzle automatically clicks of f . Do
not try to ‘‘top of f ’’ the tank, leave
some room f or the f uel to expand
with temperature changes.
Because the f uel f ill cap is on the
driver’s side of the car, park with
that side closest to the service
station pumps. Your car has an on-board ref ueling
vapor recovery system to help
keep f uel vapors f rom going into
the atmosphere. If the fuel nozzle
keeps clicking of f even though the
tank is not f ull, there may be a
problem with this system. Consult
your dealer.

A cold engine uses more f uel than a
warm engine. It is not necessary to
‘‘warm-up’’ a cold engine by letting it
idle f or a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine
will warm up f aster, and you get
better f uel economy. To cut down on
the number of ‘‘cold starts,’’ try to
combine several short trips into one.
You can improve f uel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more f uel.
Always drive in the highest gear that
allows the engine to run and acceler-
ate smoothly.
An important part of that mainte-
nance is the (see page ). For
example, an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel. It also wears out
f aster, so check the tire pressure at
least monthly. The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Turnoff theA/Cor
set the climate control to a higher
temperature to cut down on air
conditioning use. Use the f low-
through ventilation when the outside
air temperature is moderate.
The condition of your car and your
driving habits are the two most
important things that affect the fuel
mileage you get.
Always maintain your car according
to the maintenance schedule. This
will keep it in top operating condition.
In winter, the build-up of snow on
your car’s underside adds weight and
rolling resistance. Frequent cleaning
helps your f uel mileage and reduces
thechanceof corrosion.
Depending on traf f ic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your car uses extra f uel. Use the
cruise control, when appropriate, to
increase 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. START (III) does not
f unction unless the clutch pedal is
depressed.
Make sure the shif t lever is in
Park. Press on the brake pedal.
Without touching the accelerator
pedal, turn the ignition key to the
START (III) position. If the engine
does not start right away, do not
hold the key in START (III) f or
more than 15 seconds at a time.
Pause f or at least 10 seconds
bef ore trying again.
If the engine does not start within15 seconds, or starts but stalls
right away, repeat step 4 with the
accelerator pedal pressed half-way
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.
If the engine still does not start,
press the accelerator pedal all the
way down and hold it there while
starting in order to clear f looding.
As bef ore, keep the ignition key in
the START (III) position f or no
more than 15 seconds. Return to
step 5 if the engine does not start.
If it starts, lif t your f oot of f the
accelerator pedal so the engine
does not race.
An engine is harder to start in cold
weather. The thinner air f ound at
high altitude above 8,000 f eet (2,400
meters) adds to the problem. Use the f ollowing procedure:
Turn of f all electrical accessories
to reduce the drain on the battery.
Push the accelerator pedal half-
way to the f loor and hold it there
while starting the engine. Do not
hold the ignition key in START
(III) f or more than 15 seconds.
When the engine starts, release
the accelerator pedal gradually as
the engine speeds up and smooths
out.
If the engine fails to start in step 2,
push the accelerator pedal to the
f loor and hold it there while you
try to start the engine for no more
than 15 seconds. If the engine
does not start, return to step 2.

The manual transmission is synchro-
nizedinallforwardgearsforsmooth
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. Come to a full stop before you shift
into Reverse. You can damage the
transmission by trying to shif t into
Reverse with the car 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.’’
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 engine speed will not go
into the tachometer’s red zone in the
lower gear.

Rapid slowing or speeding-up
can cause loss of control on
slippery surfaces. If you crash,
you can be injured.
Use extra care when driving on
slippery surfaces.

Drive in the highest gear that lets
the engine run and accelerate
smoothly. This will give you the best
f uel economy and ef f ective emis-
sions control. The f ollowing shif t
points are recommended:If you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
RPM below the red zone.
