Important safety notes
G
WARNING
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. G
WARNING
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gasoline
to spray back out when removing the fuel
pump nozzle, which could cause personal
injury. G
WARNING
E85 fuel (ethanol) and its vapours are
poisonous, highly flammable and highly
combustible. E85 fuel can cause serious
injury
if ignited, if you come into contact with
it you or if you inhale fuel vapors. Avoid
inhaling E85 fuel vapors and avoid skin
contact with E85 fuel. Extinguish any open
flames before refueling. Keep sparks away
from E85 fuel, and do not smoke. !
Do
not use diesel to refuel vehicles with a
gasoline engine. Even small amounts of the
wrong fuel result in damage to the fuel
system and engine.
! Do not switch on the ignition if you
accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel lines.
Notify a qualified specialist workshop and
have the fuel tank and fuel lines drained
completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
Further information on fuel and on fuel grades
can be found in the "Fuel" section
(Y page 362). Refueling
