R Wash the fuel off any affected areasofs kin
with water and soap immediately.
R If you get fuel in youre yes,rinse them thor-
oughlyw ith clean water immediately.S eek
immediate medica lattention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is arisk of
fire and explosion.
Alwayst ouch the vehicle body before opening
the fuel fillerf lap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up. G
WARNING
Vehicle swithadiese lengine:
If you mix dieself uel with petrol, the flash
point of this fuel mixture is lowert han that of
pure dieself uel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is arisk of fire.
Never refuel with petrol. Never add petrol to
dieself uel.
! Do not use dieseltor
efuel vehicleswith a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong
fuel.O therwise ,the fuel wille nter the fuel
system. Even small amounts of the wrong
fuel can resultind amage to the fuel system
and the engine. Notify aqualified specialist
workshop and have the fuel tank and fuel
lines drained completely.
! Do not use petrol to refuel vehicle
swith a
diesele ngine. Do not switch on the ignition
if you accidentally refuel with the wrong
fuel.O therwise ,fuel can enter the fuel sys-
tem. Even small amounts of the wrong fuel could resultind
amage to the fuel system
and the engine. The repairc osts are high.
Notify aqualified 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 spilla
ny fuel on painted
surfaces .You could otherwis edamage the
paintwork.
! Use
afilter when adding fuel from afuel
can. The fuel lines and/or the dieseli njec-
tion system could otherwis ebeblocked by
particle sfrom the fuel can.
Do not get into the vehicle again during the
refuelling process. Otherwise ,electrostatic
charge could build up again.
If you overfill the fuel tank, some fuel may
spray out when you remove the fuel pump
nozzle.

Important safety notes
G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is arisk of fire.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle
components. In particular, do not park on dry grassland or harvested grain fields. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect.Y ou will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is arisk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle.
! Always secure the vehicle correctly
against rolling away.O therwise, the vehicle
or its drivetrain could be damaged.
To ensure that the vehicle is safeguarded
against rolling away unintentionally:
R the parking brake must be applied
R on vehicles with manual transmission,
engage 1st gear or reverse gear
R on vehicles with automatic transmission,
the transmission must be in position Pand Parking
