Coo lant
The glycol-ba sed coolant provides
exc ellent corrosion protection for the
heating and cooling systems as well
as anti-freeze protection down to ap prox .
-28 °C . It remains in the cooling system
illuminates
throughout the year and need not b e
cha ng ed.
Use of certain a nti-freezes ca n lead to
engine dam age. We therefore rec om mend
that you use only approved anti-freezes.
Anti-freeze is a danger to health; it m ust
therefore be k ept in the original conta iner
and out of the reach of children.

Warning
Anti -freeze a nd corrosion prot ect ion
Before the start of winter, have a work shop
check the anti-freeze protection. The anti-
freeze level must guarantee protection
down to a pprox. -28 °C. Insufficient anti-
freeze will reduce the frost p rotection level
and the corrosion protection. If necessary
add anti-freeze.
If c oolant loss is topped up with wa ter,
have concentration checked and a dd anti-
freeze if necessary.
