Fuel specifications

Never used leaded gasoline; it will perma-

nently damage the catalytic converter.<

Required fuel

Premium unleaded gasoline

The minimum Octane Rating is 91.

If you use gasoline with this minimum Octane

Rating, the engine may produce knocking

sounds when starting at high outside tempera-

tures. This has no effect on the engine life.

Minimum Octane Rating corresponds to the

Anti Knock Index AKI and is determined accord-

ing to the so-called (R+M)/2 method.

Use high-quality brands

Field experience has demonstrated significant

differences in fuel quality: volatility, composi-

tion, additives, etc., among gasolines offered for

sale in the United States and Canada. Fuels

containing up to and including 10% ethanol or

other oxygenates with up to 2.8% oxygen by

weight, that is, 15% MTBE or 3% methanol

plus an equivalent amount of co-solvent, will

not void the applicable warranties with respect

to defects in materials or workmanship.

The use of poor-quality fuels may result in

problems relating to drivability and start-

ing, and to a tendency to stall, especially under

certain environmental conditions such as high

ambient temperature and high altitude.

Should you encounter drivability problems,

which you suspect could be related to the fuel

you are using, we recommend that you respond

by switching to a recognized high-quality

brand.

Failure to comply with these recommendations

may also result in unscheduled maintenance.<
