Break-in Period
Help assure your vehicle's future
reliability and performance by paying
extra attention to how you drive
during the first 600 miles (1,000 km).
During this period:
Avoid full-throttle starts and rapid
acceleration.
Avoid hard braking for the first
200 miles (300 km).
Do not change the oil until the
scheduled maintenance time.
Do not tow a trailer.
You should also follow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced.

Fuel Recommendation
Your vehicle 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 performance.
Use of a gasoline with a pump octane
less than 87 can lead to engine
damage.
We recommended using a quality
gasoline containing detergent
additives that help prevent fuel
system and engine deposits.
In addition, in order to maintain good
performance, fuel economy, and
emissions control, we strongly
recommend, in areas where it is
available, the use of gasoline that
does NOT contain manganese-based
fuel additives such as MMT.
Use of gasoline with these additives
may adversely affect performance,
and cause the Malfunction Indicator
Lamp on your instrument panel to
come on. If this happens, contact
your authorized Acura dealer for
service.
Some gasoline today is blended with
oxygenates such as ethanol or
MTBE. Your vehicle is designed to
operate on oxygenated gasoline
containing up to 10 percent ethanol
by volume and up to 15 percent
MTBE by volume. Do not use
gasoline containing methanol.
If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
