The use of poor-quality fuels may result in
stalling, starting and drivability problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems that
you suspect could be related to the fuel you are
using, we recommend that you respond by
switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Fuel tank capacity
Approx. 17.7 US gal/67 liters, including the
reserve capacity of approx. 2 US gal/8 liters.
Never attempt to continue driving until
the tank is completely empty; this can
negatively affect engine function and can dam-
age the vehicle.<
Fuel specifications
Failure to comply with these recommendations
may also result in unscheduled maintenance.<
Never use leaded gasoline. Otherwise,
you will damage the catalytic converter.
Do not use flex fuel or E85, i.e. fuel that is com-
prised of 85% ethanol as these can damage the
engine and fuel supply system.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with a
lower AKI rating. The minimum AKI rating is 87.
If you use gasoline with this minimum AKI rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise, the
engine could be damaged.<
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.
