Break-in Period, Fuel Recommendation
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 exceed 5,500
rpm for the first 600 miles (1,000
km) of operation.
Do not change the oil until the
scheduled maintenance time.
Avoid hard braking for the first
200 miles (300 km).
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 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 recommend 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% ethanol by
volume and up to 15% 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.
