During this period:Avoid full-throttle starts and rapid
acceleration. If you are unable to f ind premium
unleaded gasoline, you may substi-
tute an unleaded regular gasoline.
The engine will compensate f or the
lower octane, but you may notice a
slight decrease in power as a result.
We recommend gasolines containing
detergent additives that help prevent
f uel system and engine deposits.

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).
Using gasoline containing lead will
damage your car’s emissions
controls. This contributes to air
pollution.

Refer toon page f or inf ormation
on checking other items in your
Acura. 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, see on page f or
inf ormation on adding the proper
coolant.
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 .

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 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.
The air conditioning puts an extra
load on the engine which makes it
use more f uel. For better f uel
economy, either turn of f the A/C or
switch the A/C to the economy
mode. Use the flow-through
ventilation when the outside air
temperature is moderate.
