activated for all electric windows.
Electric window roll-back function
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The roll-back function for the electric windows can reduce the risk of crush injuries when the 
windows are closing.
If the window is not able to close because it is stiff or because of an obstruction, the window will 
immediately open again ⇒.
•Check to see why the window has not closed.
•Try to close the window again.
•If the window closing process is interrupted again, the roll-back function will be disabled for a 
few seconds.
•If the window still cannot be closed, it will stop at the corresponding position. To close the 
window without the roll-back function, press the button again within a few seconds ⇒.
Careless or unsupervised use of the electric windows can cause serious injuries.
•The electric windows should be opened or closed only when you are sure that nobody 
is in their operating area.
•Never leave children or people requiring assistance alone in the vehicle when the 
vehicle is locked. The windows can no longer be opened in an emergency.
•Always take all vehicle keys with you every time you leave the vehicle. The windows 
can still be operated using the buttons in the doors for a short time after the ignition 
has been switched off, provided that the driver door and front passenger door are not 
opened.
•When transporting children on the rear bench seat, the rear electric windows should 
always be deactivated using the safety button so that they cannot be opened or closed.

WARNING 

Fig. 108 In the headliner: button for controlling the sun blind.
The electric sun blind works when the ignition is switched on.
When the glass roof is fully tilted, the sun blind is automatically moved to a ventilation position. The 
sun blind remains in the ventilation position even after the glass roof has closed.
Opening and closing the sun blind
The buttons ⇒ Fig. 108① or ② have two positions. In the first position the sun blind can be 
completely or partially opened or closed.
In the second position, the sun blind automatically moves to the final position when the button is 
pressed briefly. Press the button again to stop the one-touch function.
•Opening the sun blind: push button ① to position one. One-touch function: push button ①
briefly to position two.
•Closing the sun blind: push button ② to position one. One-touch function: push button ②

glass roof or sun blind will open again immediately if the sun blind is unable to close because it is 
stiff or obstructed.
•Check to see why the sun blind has not closed.
•Try to close the sun blind again.
•The sun blind will open again immediately if it is still unable to close because it is stiff or 
obstructed. After opening, the sun blind can be closed again within a short period of time

 Introduction
This chapter contains information on the followingsubjects:
⇒ Front controls
⇒ Operating the Climatronic system via the Infotainment system
⇒ Rear controls
⇒ Air recirculation mode
⇒ Seat heating

Closing the sun blind without the roll-back function can cause serious injuries.
•Always close the sun blind carefully.
•Ensure that nobody obstructs the path of the sun blind, especially if the roll-back 
function is not active.
•The roll-back function does not prevent fingers or other body parts from being pressed 
against the roof frame and sustaining injury.
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.

Air recirculation mode
First read and observe the introductoryinformation and safety warnings⇒
Introduction
In air recirculation mode, no outside air enters the vehicle interior.
Manual air recirculation mode
•Press the  button on the control panel to switch manual air recirculation mode on 
and off.
Automatic air recirculation mode (Climatronicyf
In automatic air recirculation mode, fresh air will enter the vehicle interior. The air recirculation 
mode will switch on automatically if the system detects an increase in the concentration of noxious 
substances in the outside air. The air recirculation mode will switch off as soon as the level of 
noxious substances has returned to normal. The system cannot detect unpleasant odours.
•Press the  button on the control panel.
•Touch function button .
•Touch the Automatic air recirculation function button.
Air recirculation mode with Air Care Climatronic
The vehicle is fitted with an allergen filter. When Air Care is activated ⇒ Air Care Climatronic, the 
air recirculation mode of the air conditioning system is maximised as far as is permitted by the risk 
of window fogging depending on the interior humidity and outside temperature. The air recirculation 
mode is automatically regulated and features continuous adjustment in order to prevent fatigue of 
the vehicle occupants.
When is the air recirculation mode deactivated?
Air recirculation mode is deactivated in the following situations ⇒:
•If the  button on the Climatronic control panel is pressed.
•If the air distribution regulator of the manual air conditioning system is turned to  position.
•If the sensor detects that the vehicle's windows might mist up.
When reversing the vehicle or when the wash and wipe system is being used, the air 
recirculation mode will switch on to prevent odours from entering the vehicle interior.
•m/k/a999MK Climatronic
If the outside temperature is very high, brief activation of manual air recirculation mode helps 
to cool the vehicle interior more quickly.
Seat heating
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Stale air can quickly make the driver tired and affect their concentration, which in turn can 
cause collisions, accidents and serious injuries.
•Never use the air recirculation mode for an extended period as no fresh air will enter 
the vehicle interior.
•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
In vehicles with an air conditioning system, do not smoke when the air recirculation mode 
is switched on. The smoke can leave a residue on the evaporator and the dust and pollen 
filter with pollution filter insert, producing a lasting unpleasant odour.
