The health of persons with limited temperature
sensitivity or a limited ability to react to high
temperatures may be aMected or they may
even suMer burn-like injuries.Do not touch the windscreen while the

function
&WARNING Danger to life due to exposure
to extreme heat or cold in the vehicle
If people, particularly children, are exposed to
extreme temperatures over an extended
period of time, there is a risk of serious injury
or danger to life.
Never leave persons, children in particu-
lar, unattended in the vehicle.&WARNING Risk of burns due to repeatedly
switching on the seat heating
Repeatedly switching on the seat heating can
cause the seat cushion and seat backrest pad-
ding to become very hot.
In particular, the health of persons with limited
temperature sensitivity or a limited ability to
react to high temperatures may be aMected or
they may even suMer burn-like injuries.
Do not repeatedly switch on the seat
heating.To protect against overheating, the seat heating
may be temporarily deactivated aser it is
switched on repeatedly.%This function is available only in vehicles with a 48 V on-board electrical system (EQ Boost
technology).
The air inside the vehicle can be heated, ventila- ted or cooled to the set temperature when thevehicle is parked.
When the vehicle is connected to power supply equipment, priority is given to charging the 48 V
battery to a speciNed minimum charge.
The running time of pre-entry climate control may be reduced under the following conditions:
= The vehicle is not connected to power supply
equipment.
= The 48 V battery is not fully charged.
With active pre-entry climate control, the charge level of the 48 V battery may be reduced, even if the charging cable connector is connected.

or heating mode automatically switches to
ventilation mode.
The stationary heater and the exhaust gas outlet
are situated behind the right-hand front wheel.
q Switching the stationary heater/ventilation
on/oM via the operating unit&DANGER Risk of fatal injury due to poison-
ous exhaust gases
If the tailpipe is blocked or suPcient ventila-
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter the vehi- cle. This is the case in enclosed spaces or if
the vehicle gets stuck in snow, for example.
Always switch the stationary heater oM in
enclosed spaces without an air extrac-
tion systems, e.g. in garages.Keep the tailpipe and the area around
the vehicle free from snow when the
engine or the stationary heater are run-
ning.Open a window on the windward side of
the vehicle to ensure an adequate supply
of fresh air.&WARNING Risk of Nre due to hot station-
ary heater components and exhaust gases
Flammable materials such as leaves, grass or
twigs may ignite.
When the stationary heater is switched
on, make sure that:
= hot vehicle parts do not come into
contact with Oammable materials.
= the exhaust gas can Oow out of the
stationary heater exhaust pipe unhin-
dered.
= the exhaust gas does not come into
contact with Oammable materials.*NOTE Battery discharge caused by sta-
tionary heater or stationary ventilation operation
Operating the stationary heater or stationary
ventilation drains the battery.
Aser heating or ventilating the vehicle
twice, drive for a longer period of time.156Climate control
