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

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.

FUEL FILL CAP
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 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 off’’ the tank, leave
some room f or the f uel to expand
with temperature changes.Shift to Park or Neutral and set
the parking brake. Pull the hood
release handle located under the
lower lef t corner of the dashboard.
The hood will pop up slightly.
Screw the f uel f ill cap back on,
tighten it until it clicks several
times. If you do not properly
tighten the cap, the Malfunction
Indicator Lamp may come on (see
page ).
Push the f uel f ill door closed until
it latches.
Your vehicle 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 full, there

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

This indicator on the instrument
panel shows which position the shif t
lever is in.
Your Acura’s transmission has f ive
f orward speeds, and is electronically
controlled f or smoother shif ting. It
also has a ‘‘lock-up’’ torque converter
forbetterfueleconomy.Youmay
f eel what seems like another shif t
when the converter locks.
The ‘‘D ’’ indicator comes on f or a
f ew seconds when you turn the
ignition switch ON (II). If it f lashes
while driving (in any shif t position),
it indicates a possible problem in the
transmission. Avoid rapid
acceleration and have the
transmission checked by an
authorized Acura dealer as soon as
possible.
The malf unction indicator lamp may
come on along with the ‘‘D ’’
indicator if there is a problem in the
automatic transmission control
system.
