Heating and air conditioning system
Heating, ventilating, cooling
Introduction
This chapter contains information on the followingsubjects:
⇒ Front controls 
⇒ Air recirculation mode 
⇒ Seat heating 
⇒ Steering wheel heating 
⇒ Troubleshooting 
The following systems may be installed in the vehicle
Both the manual air conditioning system and Climatronic heat, cool and dehumidify the air. It works
most effectively when the windows and the glass roof are closed. If heat has built up in the vehicle
interior, ventilating the vehicle can speed up the cooling process.
Display of activated functions
Lit up LEDs on rotary knobs and buttons indicate that the function is switched on.

WARNING
Poor visibility through the windows increases the risk of collisions and accidents, which can cause
serious injuries.
Keep all windows free from ice, snow and condensation to maintain good visibility.
Adjust the heating, air conditioning system and rear window heating so that condensation does not
form on the windows.
Only set off once all windows are clear.
Use air recirculation mode for a short period only. If the cooling system is switched off, condensation
can form on the windows 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 blower or switch on the air recirculation mode for an extended period as this
prevents fresh air from entering the vehicle interior.

NOTICE
Food, medicine and other items that are sensitive to heat or cold could be either damaged or
rendered useless by the air flowing out of the vents.
Never leave food, medicines or other temperature-sensitive objects in front of the vents.

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.

Some settings can be stored in the user accounts of the personalisation function and therefore
change automatically when the user account changes ⇒ Personalisation .

Water under the vehicle
If the humidity and temperature outside the vehicle are high, condensation can drip off the
evaporator of the cooling system and form a pool underneath the vehicle. This is normal and does
not indicate a leak!
If the outside humidity is high and the outside temperature low, condensation may evaporate when
the auxiliary heater is running ⇒ Auxiliary heater and ventilation . If this is the case, steam may
appear underneath the vehicle. This is not a sign that the vehicle is damaged.

WARNING
Poor visibility through all windows increases the risk of collisions and accidents, which can cause
serious injuries.
