Inner circuit of the cooling system
Make sure that the inner cooling system contains suf-
cient anti-freeze, in order to avoid corrosion. Check with
the aid of a volume gauge. See page 43 for the relevant
specications. If it appears that there is not enough anti-
freeze in the coolant, replace the liquid, as described on
page 22.

Disconnect the battery cables and charge the batteries
from time to time, during the winter period.
Filters
Drain the water from the fuel lter/water separator in
