The hot-water auxiliary heater has a heater boos-
te r,stationary heater and stationary ventilation
function.
The stationary hea ter automatically adapts its
operating mode tochanges in outside temp erature
and weather conditions. It is therefore possible
th at the stationary heater may switch from ventila-
tion toheating mode or from heating toventilation
mode.
The stationary hea ter will automatically switch
itself o. aTer a maximum of 50 minutes. The
heater booster 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 climate control byremo tecont rol or via the
multimedia system. The switch-on time is then cal-
culated based on the outside temp erature and the
activated departure time. This means that your
ve hicle is preheated or precooled bythe set depar-
ture time.
If th e departure time is reached and theve hicle is
not star ted, the auxiliary heating will continue to
ru nfo r appr oximately /ve more minutes. It will
th en switch o. automaticall y.
When the auxiliary heating is heating and theve hi-
cle is star ted, the heater booster function of the
auxiliary heating will be activated.
When the auxiliary heating is ventilating and the
ve hicle is star ted, the auxiliary heating will be auto-
matically switched o.. 130 130
