Information on low outside temperatures
Refuel your vehicle with as much winter diesel fuel
as possible at the beginning of winter.
Before changing over to winter diesel fuel, the fuel
tank should be empty, if possible. When first refu-
elling with winter diesel fuel, keep the fuel level
low, e.g. to reserve level. The fuel tank can be fil-
led as usual when next refuelling.
Further information on fuel can be obtained at a
filling station or a qualified specialist workshop.
