Fuel
Important safety notesGWARNING
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flames or smoking
materials near gasoline.
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to your
health.
Premium-grade unleaded gasoline
! To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline may be used.
If there is no premium-grade unleaded
gasoline available and regular-grade
unleaded gasoline may be used; please
observe the following precautions:
R only fill the fuel tank to half full with
regular-grade unleaded gasoline and fill
the rest with premium-grade unleaded
gasoline as soon as possible.
R do not drive at the maximum speed.
R avoid sudden acceleration.
R if the vehicle is carrying a light load, e.g.
two passengers without luggage, do not
allow the engine to rev above
3,000 rpm.
R if the vehicle is fully loaded or is being
operated in mountainous terrain, do not
depress the accelerator pedal further
than Ô of the pedal travel.
Flexible fuel vehicles
Important safety notes
Flexible fuel vehicles can be recognized by
the sticker on the inside of the filler flap.
Flexible fuel vehicles can be operated with
premium-grade unleaded gasoline and
ethanol (E85) or a mixture of both. Ethanol
fuel (E85) is a mixture of approximately 85%
ethanol and 15% unleaded gasoline.
GWARNING
Ethanol fuel (E85) and its vapors are highly
flammable, poisonous and highly
combustible. Ethanol fuel causes serious
injury if it ignites, if it comes into contact with
your skin or if you inhale the vapors. Avoid
inhaling ethanol vapors and ethanol coming
into contact with your skin. Before refueling,
extinguish all naked flames. Never allow
sparks or smoking materials near ethanol.
Changing the fuel type
For best performance and drivability, it is
recommended that you use either one or the
other fuel. Avoid alternating regularly
between the two different types of fuel.
When changing between the fuel types,
ensure that the following conditions are met:
R the fuel level is below half full.
R the fuel level is above the reserve level. This
is identifiable by the fuel tank reserve
warning lamp not being lit.
R you add more than 5 gallons (20 liters) of
fuel.
R you switch off the engine before refueling.
R the engine is started and runs for at least
five minutes immediately after refueling.
These precautions should prevent the
possibility of engine difficulties arising from
changing to a different fuel type.
If the engine still doesn't run correctly, refuel
with at least 3 US gal (12 l) of premium-grade
unleaded gasoline. This may improve the
running of the engine.
