WARNING
Fuels are toxic and harmful to health. There is a risk of injury.
You must avoid fuels coming into contact with
skin, eyes and clothes or being swallowed.
Do not inhale the fuel vapors. Keep children
away from fuels.
Keep doors and windows closed during the
refueling process.
If you or others come into contact with fuel,
observe the following points:
R Immediately rinse the fuel off your skin with
soap and water.
R If you get fuel into your eyes, immediately
rinse your eyes throughly with clean water.
Seek medical attention immediately.
R Seek medical attention immediately if fuel
has been swallowed. Do not induce vomit-
ing.

WARNING
Electrostatic charging can lead to the creation
of sparks and ignite fuel vapor. There is a risk of fire and explosion.
Touch the metallic body of the vehicle before
you open the fuel filler cap or handle the pump nozzle. Any possible electrostatic charge
present will in this way be depleted.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
! Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system. Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. 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 adding fuel from a fuel can.
The fuel lines and/or the fuel injection system could otherwise be blocked by particles fromthe fuel can.
Do not get into the vehicle again during the refu-
eling process. Otherwise, electrostatic charge
could build up again.
If you overfill the fuel tank, fuel could spray out
when the fuel pump nozzle is removed.
