⇒ Rear controls
⇒ Air recirculation mode
⇒ Seat heating
⇒ Steering wheel heating
⇒ Windscreen heating
⇒ Tips and usage notes
Closing the sun blind without the roll-back function can cause serious injuries.
•Always close the sun blind carefully.

WARNING
The following systems may be installed in the vehicle
The heating and fresh air system warms up and supplies fresh air to the vehicle interior. The
heating and fresh air system does not cool down the vehicle interior.
The manual air conditioning system or Climatronic cools down and dehumidifies the air. It
works most effectively when the windows and the glass roof are closed. If heat has built up in the
vehicle interior, opening the doors and windows can speed up the cooling process.
How the vehicle displays active functions
Lit up LEDs on rotary knobs and buttons indicate that a function has been switched on.
Some settings can be stored in the user accounts of the personalisation function and
therefore change when the user account changes ⇒ Personalisation.
Front controls
Fig. 109 In the upper section of the centre console: controls for the manual air conditioning system.
Poor visibility through the windows increases the risk of collisions and accidents, which
can cause serious injuries.
•Keep all windows free of ice, snow and misting to ensure good visibility.
•Set the heating, air conditioning and rear window heating controls to prevent the
windows from misting up.
•Only set off once all door windows, the windscreen and the rear window are clear.
•Use air recirculation mode only for short periods. If the cooling system is switched off,
the windows can mist up very quickly in air recirculation mode and reduce visibility
considerably.
•Switch off the air recirculation mode when it is no longer required.
WARNING
Stale air can quickly make the driver tired and affect their concentration, which in turn can
cause collisions, accidents and serious injuries.
•Never switch off the blowers or switch on the air recirculation mode for longer periods
as this prevents fresh air from entering the vehicle interior.
WARNING
Do not place any food, medicine or any other temperature-sensitive items in front of the
vents. Heat-sensitive food, medicine and other items could be either damaged or rendered
useless.
NOTICE
If the air conditioning system is not working, switch the air conditioning system off
immediately and have it checked by a qualified workshop. This can help to prevent
secondary damage.
