Warm and cold

Warm and cold
Climate control system
One of the following options may be available,
depending on vehicle equipment
— A deluxe automatic climate control system with
3 zones where the temperature, air distribu-
tion, and air supply can be set separately on the
left front side, the right front side, and in the
rear
— A deluxe automatic climate control system with
4 zones to individually adjust the temperature,
air distribution, and amount of ventilation at all
of the seats
The climate control system warms, cools, dehu-
midifies, and filters the air in the vehicle interior.
It is the most effective when the windows and
panoramic glass roof* are closed. If there is a
build-up of heat inside the vehicle, ventilation
can help to speed up the cooling process.
The climate control system automatically main-
tains a temperature once it has been set. In all
heating mode functions except defrost, the blow-
er only switches to a higher speed once the en-
gine coolant has reached a certain temperature.
@ For the sake of the environment
Energy can be saved by switching off the A/C
mode.
@ Tips
— To prevent interference with the heating
and cooling output and to prevent the win-
dows from fogging over, the air intake in
front of the windshield must be free of ice,
snow, and leaves.
— Condensation from the cooling system can
drip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak.
— The energy management system may tem-
porarily switch off certain functions, such as
the seat heating” or rear window defogger.

These systems are available again as soon as
the energy supply has been restored.
— Certain settings are stored automatically in
the active personal profile.
