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.
Do not change the oil until the
scheduled maintenance time.
Avoid hard braking for the first
200 miles (300 km).
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 unleaded gasoline with a pump
octane number of 86 or higher. Use
of a lower octane gasoline can cause
a persistent, heavy metallic rapping
noise that can lead to engine damage.
On EX-V6 with manual transmission
If you drive with the low engine
speed (below than about 1,000 rpm),
you may feel the engine knocking. In
this case, you can use premium
unleaded gasoline with a pump
octane number of 91 or higher to
prevent the engine from knocking.
We recommend using 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 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.
