Fuel specifications
Do not fill the tank with leaded fuel, as this
would cause permanent damage to 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 affect on the engine life.
Minimum octane rating corresponds to the Anti
Knock Index AKI and is determined according
to the so-called (R+M)/2 method.
Do not fill the tank with leaded fuel, as this
would cause permanent damage to the
catalytic converter.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing 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
drivability, starting and stalling problems
especially under certain environmental condi-
tions 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.<
