13.5.1 Checking the fluid level
Switch off the hot-water heater and allow it to cool down.
Check if the fluid level is between the marks "MIN" (Fig. 185,3) and "MAX"
(Fig. 185,2) on the compensator reservoir (Fig. 185).
13.5.2 Topping up heating fluid
Position the vehicle horizontally. This prevents the formation of bubbles.
Switch off the hot-water heater and allow it to cool down.
Unscrew or pull off the panel.
Open the rotary lid (Fig. 185,1) on the compensator reservoir.
Slowly remove cover with circulating pump upwards.
Check anti-freeze with an anti-freeze hydrometer. The frost protection con-
tent must be 40 % or correspond to a frost protection of -25 °C.
Fill water frost protection mixture slowly into the compensator reservoir.
13.5.3 Bleeding the heating system
The bleeding valves are built in nearby the radiators.
Switch off the hot-water heater and allow it to cool down.
Open bleeding valve (Fig. 186,1) and leave open until no more air escapes.
