In the vehicle Operator's Manual, information and recommendations can be found on:
Rusing automatic climate control
Rusing the rear control panel
Rthe individual functions
Observe these notes for optimal use of the automatic climate control.
The "Cooling with air dehumidification" function is even available when the engine is not running
(
Ypage 17).
Use the residual heat function if you want to heat or ventilate the vehicle interior when the ignition is switched off. The residual heat function can only be activated or deactivated with the ignition
switched off. When the ignition is switched on, the residual heat function is switched off
(
Ypage 17).
Operating the climate control sys-
tems
Switching cooling with air dehumidi-
fication on/off
If you deactivate the "Cooling with air-dehumid-ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly.
The "Cooling with air dehumidification" function
is available even when the engine is not running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.
XTo activate: press the¿orÁ button.
The indicator lamp in the ¿orÁ button
lights up.
XTo deactivate: press the¿orÁ but-
ton.
The indicator lamp in the ¿orÁ button
goes out. The "Cooling with air dehumidifica-
tion" function has a delayed switch-off fea-
ture.
Switching the residual heat on or off
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.
XTo activate: press theÌorÁ button.
The indicator lamp in the ÌorÁ button
lights up.
XTo deactivate: press theÌorÁ but-
ton.
The indicator lamp in the ÌorÁ button
goes out.
The blower will run at a low speed regardless of
the airflow setting.
If you activate the residual heat function at high
temperatures, only the ventilation will be acti-
vated. The blower runs at medium speed.
Residual heat is deactivated automatically:
Rafter approximately 30 minutes

Key
General notes
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
SmartKey" can be activated.
When the vehicle is pre-cooled, the following
functions are activated if required:
RClimate control system
RBlower
RSeat ventilation
Operating the climate control systems17
Climate control
When the vehicle is pre-heated, the following
functions are activated if required:
RClimate control system
RBlower
RSeat heating
If you have activated ionization via the multime-
dia system, it is activated together with pre-
entry climate control.
Activating/deactivating
Before "Pre-entry climate control via SmartKey"
can be activated, you must activate the function
using the on-board computer.
XTo activate: unlock the vehicle with the
SmartKey or KEYLESS-GO.
The climate control functions are activated
for up to 5 minutes for pre-heating and pre-
cooling.
XTo deactivate: "Pre-entry climate control via
SmartKey" deactivates automatically when
the engine is started.
The following functions remain active after the
engine is started:
RSeat heating (heating)
RSeat ventilation (ventilation)

Problems with "Pre-entry climate control via SmartKey"
ProblemPossible causes/consequences and MSolutions
"Pre-entry climate con-
trol via SmartKey" can-
not be switched on or
has switched itself off.The condition of charge of the high-voltage battery is under the speci-
fied minimum condition of charge.
XStart the engine when the vehicle is at a standstill.
The engine powers the electric motor. The electric motor operates
as a generator. The high-voltage battery is being charged.
Further information on charging the high-voltage battery via:
Ra mains socket (Ypage 31)
Ra charging station (Ypage 35)
Ra wallbox (Ypage 34)
"Pre-entry climate control via SmartKey" has been started more than
twice with the engine switched off.
XSwitch on the engine and let it run for more than ten seconds.
XTry again to switch on "Pre-entry climate control via SmartKey".
Pre-entry climate control at time of
departure
Important safety notes
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
General notes
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. The condition of charge of
the high-voltage battery must be higher than the
specified minimum condition of charge, how-
ever.
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.
