Important safety notes
G
WARNING
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heating
before refuelling. G
WARNING
Avoid contact with fuels.
It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours. G
WARNING
Do not use petrol to refuel adiesel tank.N ever
mix diesel with petrol. Doin gsocould damage
the fuel system and the engine. The vehicle
could also catc hfire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel vehicles with
apetrol engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and the engine.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify
aq ualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely.
! 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 afilter when adding fuel from afuel
can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.

Important safety notes
G
WARNING
If flammable materials such as leaves, grass
or twigs are exposed to prolonged contact to
parts of the exhaust system that heat up, they
could ignite. There is arisk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
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 unsupervised in the vehi-
cle, they could set it in motion by, for example:
R releasing the parking brake
R shifting the automatic transmission out of
the parking position P
R starting the engine.
They could also operate the vehicle's equip-
ment.T here isarisk of an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unsupervised in the vehicle.
! Am oving vehicle can lead to damage to
the vehicle or damage to the drive train.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied.
R the transmission must be in position Pand
the key must be removed from the ignition
lock.
R on uphill or downhill gradients, the front
wheels must be turned towards the kerb. Parking

! Vehicles with adiesel particle filter: if
the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur during the automatic cleaning of the
diesel particle filter. This may lead to fuel
collectin ginthe engin eoil and cause
engin efailure. Therefore, if you frequently
drive short distances, you should tak ea20
minut etriponam otorway or rural road at
least every 500km. Brakes

WARNING
If you shift down on aslippery road surfac ein
an attempt to increase the engine's braking
effect ,the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engin ebrak-
ing on aslippery road surface.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden, you must select

R you lock the vehicle within approximately
60 seconds
When parking, position your vehicle so that
it does not make contact with the kerb as
the vehicle is lowered. Your vehicle could
otherwise be damaged.

cally. All-round level control ensures the best
possible suspension and constant ground
clearance, even with aladen vehicle. When
you drive fast, the vehicle is lowered auto-
matically to improve driving safety and to
reduce fuel consumption. Driving systems
