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.
You should also follow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced.

200 miles (300 km).
Do not change the oil until the
scheduled maintenance time.
Your vehicle is designed to operate
on unleaded gasoline with a pump
octane number of 87 or higher. Use
of a lower octane gasoline can cause
a persistent, heavy, metallic rapping
noise that can lead to engine damage.
Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane number of 91 or higher.
Useofaloweroctanegasolinecan
cause occasional metallic knocking
noises in the engine and will result in
decreased engine performance. Use
of a gasoline with a pump octane
number less than 87 can lead to
engine damage.
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.
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.
We recommend using quality
gasolines containing detergent
additives that help prevent fuel
system and engine deposits.
You may hear a knocking noise from
the engine if you drive the vehicle at
low engine speed (below about 1,000
rpm) in a higher gear. To stop this,
raise the engine speed by shifting to
a lower gear.
