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:Avoid full-throttle starts and rapid
acceleration. Youshouldfollowthesesamere-
commendations with an overhauled
or exchanged engine, or when the
brakes are replaced.
Do not change the oil until the
recommended time or mileage
intervalshowninthemaintenance
schedule.
Avoidhardbraking.Newbrakes
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.
Use of a lower octane gasoline can
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 vehicle’s emissions
controls. This contributes to air
pollution.
We also recommend that you do not
tow a trailer during the f irst 500
miles (800 km).

Because the f uel f ill cap is on the
driver’s side of the vehicle, park
with that side closest to the
service station pumps.
Open the f uel f ill door by pulling
onthehandletotheleftof the
driver’s seat.
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.

Remove the dipstick again and
check the level. It should be
between the upper and lower

radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see
on page f or

The condition of your vehicle and
your driving habits are the two most
important things that affect the fuel
mileage you get.
Always maintain your vehicle accord-
ing to the maintenance schedule.
This will keep it in top operating
condition.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.
Depending on traf f ic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your vehicle uses extra f uel. Use the
cruise control, when appropriate, to
increase f uel economy.
The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Turnoff theA/Cto
cut down on air conditioning use.
Use the f low-through ventilation
when the outside air temperature is
moderate.
In winter, the build-up of snow on
your vehicle’s underside adds weight
and rolling resistance. Frequent
cleaning helps your f uel mileage and
reduces the chance of corrosion. 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. 305

Apply the parking brake.
In cold weather, turn of f all
electrical accessories to reduce
the drain on the battery.
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 within
15 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.
