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.
Do not change the oil until the
scheduled maintenance time.
Avoidhardbrakingforthefirst
200 miles (300 km).
Do not tow a trailer.
You should also f ollow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced. Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane number of 91 or higher.
Useof aloweroctanegasolinecan
cause occasional metallic knocking
noises in the engine and will result in
decreased engine perf ormance. Use
of a gasoline with a pump octane
number less than 87 can lead to
engine damage.
Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane of 91 or higher. If this
octane grade is unavailable, regular
unleaded gasoline with a pump
octane of 87 or higher may be used
temporarily. The use of regular
unleaded gasoline can cause metallic
knocking noises in the engine and
will result in decreased engine
perf ormance. The long-term use of
regular-grade gasoline can lead toengine damage.
We recommend using quality
gasolines containing detergent
additives that help prevent fuel
system and engine deposits.
In addition, in order to maintain good
perf ormance, f uel economy, and
emissions control, we strongly
recommend, in areas where it is
available, the use of gasoline that
does NOT contain manganese-based
f uel additives such as MMT.
Use of gasoline with these additives
may adversely af f ect perf ormance,
and cause the malfunction indicator
lamp on your instrument panel to
come on. If this happens, contact
your authorized dealer f or service.4-cylinder models

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.The vehicle doors and the f uel f ill
door will automatically relock if
the remote transmitter unlock
f unction is used. In this instance,
the security relock f unction can be

You may hear a knocking noise from
the engine if you drive the vehicle at
low engine speed (below about 1,000

raise the engine speed by shif ting to
a lower gear.
