Many drivers use the air conditioning in their vehicle incorrectly.
Find out how to do it better here.
Without air conditioning, driving in the summer can be torture.
However, the interior cooling should be used correctly.
Proper maintenance is also important.
Five tips for the hot season.
Ventilate the car before driving
Anyone who has parked the car in the blazing sun should make it as easy as possible for the air conditioning to start driving.
Ideally, when the vehicle is stationary, you should open all the doors and flaps
to get rid of the accumulated heat.
If necessary, this can also be done while driving with the windows open.
If the inside and outside temperature have equalized but are still too high, the air conditioning is
first set to recirculation
in order to reach the set values quickly and efficiently.
Only then is hot air to be cooled from the outside used again.
Avoid getting cold
If the system is switched on, the air outlet nozzles should
only be directed towards clothed parts of the body
If the air, which can be up to four degrees cold, hits bare skin directly, there is a risk of
colds and muscle strains
In general, the difference to the outside temperature should not be too great.
Otherwise there is a risk of heat shock when getting out.
a maximum difference of six degrees
Drive to the workshop
Many car workshops offer air conditioning checks at the beginning of the warm season.
In newer cars with a perfectly functioning system, you can usually save yourself that.
The vehicle manufacturers themselves usually only recommend a check in the maintenance specifications when the cooling capacity decreases.
But there is another case in which it is worth consulting an expert: if the air vents smell stinky, this can be due to a build-up of bacteria.
The evaporator and lines must then be
cleaned and disinfected
Turn off the air conditioner early
The correct handling of the air conditioning in the car needs to be learned.

Musty bacteria are also caused by condensation.
In order to avoid this as far as possible, you should
switch off the cooling function using the A/C button shortly before the end of the journey
However, the blower remains on.
In general, you should always pay attention to the air conditioning system: It is therefore advisable to use it occasionally in autumn and winter.
On the one hand, it removes moisture from the air and thus prevents the windows from fogging up, on the other hand, the lubrication of the moving parts remains in good condition.
Expect additional consumption
According to ADAC measurements, an air conditioning system consumes an
extra 0.5 to 1.0 liters per 100 kilometers on
an annual average .
During the cooling phase in summer use, it can sometimes
be up to 4 liters
So having the air conditioning on full power and the windows open at the same time is not a good idea.
At the same time, you shouldn't switch off the cooling completely out of false frugality.
Because a pleasant temperature in the interior is not only a feel-good factor, but also a safety factor.
Studies have shown that the driver's reaction speed decreases by 20 percent when the vehicle is very hot.
