General information
Check filter at shorter intervals in the case
of extreme op erating conditions such as
high humidity (primarily in coastal areas),
extremely high or low outside temp eratures
and substantially v arying daytim e and
night-time tem peratures.
Coolant
During operation the system is pressurised.
The temperature may therefore rise briefly
to over 100 °C.
The glycol-based coolant p rov id es
excellent corrosion protection for the
hea ting and cooling systems as well a s
anti-freeze protection down to approx.
–28 °C. It remains in the cooling system
throug hout the yea r and need not be
changed in vehic les with petrol engine or

requirem ents regarding disposal of
