Problems with the rear window heating
Problem
Possible causes/consequences and
M
MSolutions The rear window heating
has switched off prema-
turely or cannot be
switched on. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading lamps,
interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window heating
can be switched on again. Switching air-recirculation mode
on/off
General notes You can deactivate the flow of fresh air tempo-
rarily if unpleasant odours are entering the vehi-
cle from outside. The air already inside the vehi- cle will then be recirculated.
If you switch on air-recirculation mode, the win-
dows can mist up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from mist- ing up.

Ionisation can only be operated when the auto-
matic climate control is switched on. The side air vent on the driver's side must be open. Pre-entry climate control via key
General notes The "Pre-entry climate control via key" function
is only available n PLUG-IN HYBRID vehicles.
Before getting in, the vehicle interior can be
briefly warmed or ventilated in advance and the
air from the air vents can be pre-cooled.
The high-voltage battery must be sufficiently
charged before "Pre-entry climate control via
key" can be activated.
When the vehicle is pre-cooled, the following
functions are activated as needed:
R Automatic climate control
R Blower
R Seat ventilation
When the vehicle is pre-heated, the following
functions are activated as needed:
R Automatic climate control
R Blower
R Seat heating
If you have activated ionisation via the multime- dia system, it is activated together with pre-
entry climate control.
Switch on ionisation (see the separate operating instructions).
Activating/deactivating "Pre-entry cli-
mate control via key" Before "Pre-entry climate control via key" can be
activated, you must activate the function using
the on-board computer.
X To activate "Pre-entry climate control via
key": unlock the vehicle with the key or KEY-
LESS-GO.
The climate control functions are activated for
up to 5 minutes for pre-heating and pre-cooling.
To deactivate "Pre-entry climate control via
key": "Pre-entry climate control via key" deac-
tivates automatically when the engine is started. The following functions remain active after the
engine is started:
R Seat heating (heating)
R Seat ventilation (ventilation)

Setting the departure time
You can set the departure time using the on-
board computer or via the Mercedes connect
me web App. The activation of the "Pre-entry
climate control at departure time" function can
be linked to this departure time. Your vehicle will then be cooled or heated until the desired tem-perature is reached in time for the set departure
time. "Pre-entry climate control at departure
time" will be activated a maximum of 55 minutes before departure. If the departure is delayed,
the vehicle will be heated or cooled for a further five minutes.
X To set the departure time: set the departure
time using the on-board computer
(Y page 292). Set the departure time using
the Mercedes connect me web App: http://
www.mercedes.me.
X To activate or deactivate "Pre-entry cli-
mate control at departure time": activate
or deactivate "Pre-entry climate control at
departure time" using the on-board com-
puter. Activate or deactivate "Pre-entry cli-
mate control at departure time" using the
Mercedes connect me web App: http://
www.mercedes.me.
The "Pre-entry climate control at departure
time" function is automatically deactivated
when the vehicle is started. The following func-
tions remain active:
R Seat heating
R Seat ventilation
R Ionisation
To deactivate "Pre-entry climate control at
departure time": the activated "Pre-entry cli-
mate control at departure time" can be deacti-
vated using the button (Y page 149).
Activating/deactivating "Immediate
pre-entry climate control" via the but-
ton You can activate "Immediate pre-entry climate
control" even if the vehicle interior is already at
the desired temperature. This means, for exam- ple, that the vehicle interior continues to be
cooled or heated if the journey is interrupted for
up to 50 minutes and the interior temperature is kept constant. X
To activate or deactivate "Immediate pre-
entry climate control": press button:.
The blue or red indicator lamp in the button
lights up or goes out.
The colours of the indicator lamps on button :
have the following meanings:
R blue: cooling activated
R red: heating activated
R yellow: departure time is preselected Auxiliary heating
Important safety notes G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac- tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot. Operating the climate control system
