Refuelling

G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heat-
ing* before refuelling.
G
Risk of injury
Do not allow fuel to come into contact with
skin or clothing. Direct skin contact with fu-
els and the inhalation of fuel vapours are
damaging to health.
G
Risk of fire
Do not use petrol to refuel vehicles with a
diesel engine. Do not mix diesel with petrol.
This would result in damage to the fuel sys-
tem and engine, which could lead to a vehi-
cle fire.
!
Damage which occurs as a result of adding
petrol to diesel is not covered by the warranty.
