them.
The automatic climate control
system in your Acura picks the
proper combination of air condi-
tioning, heating, and ventilation to
maintain the interior temperature
you select. The system also adjusts
the fan speed and air flow levels.
The direction of air f low f rom the
vents in the center and each side of
the dashboard is adjustable.
The climate control system draws air
through the exterior vents at the
bottom of the windshield. Keep
these vents clear of leaves and other
debris.
For the climate control system to
provide heating and cooling, the
engine must be running.
To adjust the air f low f rom a vent,
move the tab up-and-down and side-
to-side.

During this period:Avoid full-throttle starts and rapid
acceleration. We recommend gasolines containing
detergent additives that help prevent
f uel system and engine deposits.

km).
Open the f uel f ill door by pushing

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).
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.
Using gasoline containing lead will
damage your car’s emissions
controls. This contributes to air
pollution.
Youshouldfollowthesesamere-
commendations with an overhauled
or exchanged engine, or when the
brakes are relined. Do not change the oil until the
recommended time or mileage
intervalshowninthemaintenance
schedule. Your Acura is designed to operate on
premium unleaded gasoline with a
pump octane number of 91 or higher.
Useof aloweroctanegasolinecan
cause a persistent, heavy metallic
rapping noise in the engine that can
lead to mechanical damage.
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.

Push the f uel f ill door closed until
it latches.
Remove the f uel f ill cap slowly.
You may hear a hissing sound as
pressure inside the tank escapes.
The fuel fill cap is attached to the
f uel f iller with a tether. Put the
attachment on the f uel f ill cap into
the slit on the f uel f ill door.
Stop f illing the tank af ter the f uel
nozzle automatically clicks of f . Do
not try to ‘‘top off’’ the tank, leave
some room f or the f uel to expand
with temperature changes.
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. Screw the f uel f ill cap back on,
tighten it until it clicks at least
three times. If you do not properly
tighten the cap, the Malfunction

radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, seeon page f or
inf ormation on adding the proper
coolant. Refer to

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.
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.
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.
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.
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.
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. 242 Driving Habits
