PREVENTATIVE MAINTENANCE BEFORE THE WINTER SEASON
Your authorized Service dealer can always give you good advice to prepare
your vehicle for winter.
DIESEL FUEL
If outside temperatures are persistently low, only fill up with winter diesel oil
produced by a reputable oil company.
During the winter months the oil companies often use additives, to prevent
blockages caused by the precipitation of paraffin crystals (wax deposits).
It is not permitted to use your own fuel additives.
NOTE
Additives which are used to prevent precipitation of paraffin crystals have
a purely preventative effect. They can not dissolve the paraffin crystals
once they have been precipitated.
Always carry a spare fuel fine filter in the vehicle so that you can replace
it quickly if it becomes blocked in any way (for example, by paraffin
crystals).
Always preferably fill up in the evenings to prevent condensation
(especially in winter).
