The heating and fresh air system cannot be switched on or its function is restricted
The heating and defrost function are more effective when the engine is warm.
1. If the fault persists, consult a suitably qualified workshop.
Condensation on the windows
Condensation forms on the windows if they are colder than the ambient temperature and the air is very humid. Cold
air can absorb less moisture than warm air, which is why condensation frequently forms on windows in cold weather.
1. Keep the air intake in front of the windscreen free from ice, snow and leaves to improve the heating or cooling
output (→ Vehicle care).
2. Do not cover the air vents in the rear of the luggage compartment so that air can flow through the vehicle from
the front to the rear.
3. Switch on the defrost function (→ Heating, ventilation and cooling).
The wrong unit of temperature has been set
1. Change the unit of temperature for all temperature displays in the vehicle using the Infotainment system
(→ Vehicle settings menu).
Water or water vapour under the vehicle
If the humidity and temperature outside the vehicle are high, condensation can drip off the evaporator in 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. If this is the case, steam may appear underneath the vehicle. The vehicle is not damaged.
Touch panels do not react as expected
Moisture, dirt and grease can impede the functioning of the touch panels.
1. Always keep touch panels clean and dry.
