Solutions
"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.

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".
Switch on ionisation (see the separate operating
instructions).
