Keep theta ilpipe and the area around
th eve hicle free from snow when the
engine or thest ationary heater are run‐

Obser vethe no tes on auxiliary heating
(/ page 126).
The hot-water auxiliary hea ter has a heater boos‐
te r,stationary heater and stationary ventilation
function. In addition, the auxiliary heating sy stem
heats the engine coolant toprotect the engine.
The stationary heater automatically adapts its
operating mode tochanges in outside temp era‐
ture and weather conditions. It is therefore possi‐
ble that thest ationary heater may swit chfrom
ve ntilation toheating mode or from heating to
ve ntilation mode.
The stationary heater will automatically swit ch
itself off af ter a maximum of 50 minutes. The
heater boos ter function helps toheat up theve hi‐
cle while the engine is running and at low outside
te mp eratures.
Yo u can set up tothre e departure times for pre-
entry clima tecontrol byremo tecontrol or via the
multimedia sy stem. The switch-on time is then
calculated based on the outside temp erature and
th e activated departure time. This means that
yo ur vehicle is preheated or precooled bythe set
departure time.
If th e departure time is reached and the engine is
not star ted, the auxiliary heating will continue to Climate cont

When the auxiliary heating is heating and the
