Stowing and using

Make sure that the luggage compartment lid
and the panoramic glass roof* do not come in-
to contact with objects on the roof when they
are open.
Energy usage will increase because of the in-
creased wind resistance. Remove the roof rack
when you are no longer using it.

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.
104

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

the risk of injury, these individuals should
not use seat heating”.
