2003 Acura MDX octane

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.

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.

The Maintenance Schedule specif ies
how of ten you should have your
vehicle serviced and what things
need attention. It is essential that
you have your vehicle serviced as
scheduled to retain its high level of
saf ety, dependability, and emissions
control perf ormance.Service your vehicle according to the
time and mileage periods on one of
the Maintenance Schedules on the
f ollowing pages. Select the schedule
f or ‘‘Severe Conditions’’ if most of
your driving is done under one or
more of the conditions listed on that
page. Otherwise, f ollow the schedule
f or ‘‘Normal Conditions.’’
The services and time or distance
intervals shown in the maintenance
schedule assume you will use your
vehicle as normal transportation f or
passengers and their possessions.
You should also f ollow these
recommendations:
Avoid exceeding your vehicle’s
load limit. This puts excess stress
on the engine, brakes, and many
other parts of your vehicle. The
load limit is shown on the tire
inf ormation label on the driver’s
doorjamb. Operate your vehicle on
reasonable roads within the legal
speed limit.
Drive your vehicle regularly over a
distance of several miles
(kilometers).
Always use unleaded gasoline with
theproperoctanerating(seepage
).

Some conventional gasolines are
being blended with alcohol or an
ether compound. These gasolines
are collectively ref erred to as
oxygenated f uels. To meet clean air
standards, some areas of the United
States and Canada use oxygenated
f uels to help reduce emissions.
If you use an oxygenated f uel, be
sure it is unleaded and meets the
minimum octane rating requirement.
Bef ore using an oxygenated f uel, try
to conf irm the f uel’s contents. Some
states/provinces require this
informationtobepostedonthe
pump.The f ollowing are the U.S. EPA and
Canadian CGSB approved
percentages of oxygenates:
(Methyl Tertiary Butyl
Ether)
You may use gasoline containing up
to 15 percent MTBE by volume. (ethyl or grain alcohol)
You may use gasoline containing up
to 10 percent ethanol by volume.
Gasoline containing ethanol may be
marketed under the name ‘‘Gasohol.’’
(methyl or wood
alcohol)
Your vehicle was not designed to use
fuel that contains methanol.
Methanol can corrode metal parts in
the fuel system, and also damage
plastic and rubber components. This
damage would not be covered by
your warranties. If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
Fuel system damage or perf ormance
problems resulting f rom the use of
an oxygenated f uel containing more
than the percentages of oxygenates
given above are not covered under
warranty.

If you are planning to take your
Acura outside the U.S., contact the
tourist bureaus in the areas you will
betravelingintofindoutaboutthe
availability of unleaded gasoline with
theproperoctanerating.
If unleaded gasoline is not available,
be aware that using leaded gasoline
in your Acura will af f ect perf or-
mance and fuel mileage, and damage
its emissions controls. It will no
longer comply with U.S. and
Canadian emissions regulations, and
will be illegal to operate in North
America. To bring your vehicle back
into compliance will require the re-
placement of several components,
such as the oxygen sensors and the
three way catalytic converter. These
replacements are not covered under
warranty.
