FUEL RECOMMENDATION
Fuel recommendation
EXAMPLE
E20
To avoid damaging catalytic converter, you
must use unleaded gasoline with an
octane number (RON) of 91 or higher. This
is identified by a label attached on fuel lid
that states: "UNLEADED FUEL ONLY",
"NUR UNVERBLEITES BENZIN",
"ENDAST BLYFRI BENSIN" or "SOLO
GASOLINA SIN PLOMO".
1-1
Gasoline-ethanol blends
Blends of unleaded gasoline and ethanol
(grain alcohol), also known as gasohol, are
commercially available in certain areas.
Blends of this type may be used in your
vehicle if they are no more than 20% etha-
nol. Check that this gasoline-ethanol blend
has octane ratings no lower than those
recommended for the gasoline.
Gasoline containing MTBE
Unleaded gasoline containing
(methyl tertiary butyl ether) may be used in
your vehicle if the MTBE content is not
greater than 15%. This oxygenated fuel
does not contain alcohol.
NOTICE
57RK109
The fuel tank has an air space to
allow for fuel expansion in hot
weather. If you continue to add fuel
after the filler nozzle has automati-
cally shut off or an initial blowback
occurs, the air chamber will become
full. Exposure to heat when fully
fuelled in this manner will result in
leakage due to fuel expansion. To
prevent such fuel leakage, stop filling
after the filler nozzle has automati-
cally shut off, or when initial vent
blowback occurs, if using an alterna-
tive non-automatic system.
NOTICE
Be careful not to spill fuel containing
alcohol while refueling. If fuel is
spilled on the vehicle body, wipe it up
immediately. Fuels containing alco-
hol can cause paint damage, which is
not covered under the New Vehicle
Limited Warranty.
