X Consult a qualified specialist workshop. Setting climate control to automatic
mode
General notes In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature of the dispensed air, the airflow and the air dis- tribution.
The "Cooling with air dehumidification" function
is activated automatically in automatic mode.
In the rear compartment, you can also switch
climate control for the rear seats to automatic
mode using the Ãbutton.

draw. You should therefore switch it off as soon
as the window is clear. It otherwise switches off automatically after several minutes.
If the battery voltage is too low, the rear window
heating may switch off.

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.

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.

General notes It is possible to make use of the residual heat of
the engine to continue heating the stationary
vehicle for up to 30 minutesafter the engine has been switched off. The heating time depends on
the set interior temperature.
Switching on/off X
To switch on: press theÌorÁ button.
The indicator lamp in the ÌorÁ button
lights up.
i The blower will run at a low speed regardless
of the airflow setting.
i If you activate the residual heat function at
high temperatures, only the ventilation will be
activated. The blower runs at medium speed.
X To switch off: press theÌorÁ but-
ton.
The indicator lamp in the ÌorÁ button
goes out.
Residual heat is deactivated automatically:
R after approximately 30 minutes
R when the ignition is switched on
R if the battery voltage drops
R when the auxiliary heating is switched on Ionisation
Ionisation is used to purify and freshen the air in
the vehicle interior, which is conducive to a
pleasant climate.
The ionisation of the interior air is odourless and cannot, directly, be perceived in the vehicle inte-
rior.
You can switch ionisation on and off via the mul- timedia system (see the separate operating
instructions). 146
Operating the climate control systemClimate control

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)
R Ionisation

MSolutions "Pre-entry climate con-
trol via key" cannot be
activated or has been
deactivated. The charge status of the high-voltage battery is under the specified
minimum charge status.
X Start the engine when the vehicle is at a standstill.
The internal combustion engine drives the electric motor. The elec-
tric motor is operating as an alternator. The high-voltage battery is
charging.
Further information on charging the high-voltage battery via: R a mains socket (Y page 185)
R a charging station (Y page 189)
R a wallbox (Y page 188) "Pre-entry climate control via key" has been started more than twice
with the engine switched off.
X Switch on the engine and let it run for more than ten seconds.
X Try again to activate "Pre-entry climate control via key". Pre-entry climate control at time of
departure
Important safety notes G
WARNING
If persons (particularly children) are exposed
to heat or cold for a prolonged period, there is a risk of serious or even fatal injuries. Never
leave persons (particularly children) unatten-
ded in the vehicle.
General notes The "Pre-entry climate control at departure
time" function is only available in PLUG-IN
HYBRID vehicles.
You can use the "Pre-entry climate control at
departure time" function to cool or heat the
vehicle interior if the engine is not running.
The "Pre-entry climate control at departure
time" function can be activated regardless of
whether or not the vehicle is connected to an
electric power supply. However, the charge sta- tus of the high-voltage battery must be higher
than the specified minimum charge status.
When the vehicle is connected to an electric
power supply, priority is given to charging the
high-voltage battery to the specified minimum charge. "Pre-entry climate control at departure
time" is only activated subsequently.
The running time of the "Pre-entry climate con-
trol at departure time" function may be reduced if:
R the vehicle is not connected to an electric
power supply and
R the high-voltage battery is not fully charged
With active "Pre-entry climate control at depar-
ture time" the charge status of the high-voltage
battery can be reduced, even if the charge cable
connector is connected.
When the vehicle is cooled, the following func-
tions are activated as needed:
R Automatic climate control
R Blower
R Seat ventilation
When the vehicle is heated, the following func-
tions 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".
