Summer Hazards

Cooling down on hot days

Anyone who has ever been travelling with over 30 degree weather in a car without air conditioning will understand it. The risk of accidents increases in the summer because when the temperature rises to above 30 degrees, the body is stressed by the warming. 

The consequences are lowered concentration, decreased visual accuracy, tiredness and slowed reactivity. 

A pleasant climate in the car is an important prerequisite for a safe journey. Ideal temperatures are between 21 and 23 degrees. 

Maintain the air conditioner properly

Most newly registered cars have air conditioning, but how can you ensure that your system works well and lasts a long time? 

Prevent refigerant loss

By diffusion, the air conditioner loses eight to ten percent of refrigerant per year. You should therefore switch on the air conditioning regularly - even at lower temperatures - once a week for at least ten minutes. This keeps the refrigerant in the cooling circuit and prevents the seals from drying out.

Changing the filter

For the air conditioning system to work properly, the interior filter must be replaced regularly, preferably in a specialist workshop. Workshops recommend a filter change after one year or 15,000 kilometers. A replacement is useful in the spring because dirt and moisture can accumulate in the filter in the winter. As a result, bacteria and mold increase which can lead to additional climate impact in the vehicle.

You can also have your air conditioning system equipped with a conventional filter converted to an activated carbon cabin filter. This way, pollen and fine dust are guaranteed to stay outside!

Tips for driving in high heat

If possible, choose a shady spot or a garage for parking as temperature in the vehicle can rise one degree Celsius per minute in intense light. 

Never leave small children or animals in the car - ten minutes in an overheated vehicle can lead to circulatory collapse and thus become life-threatening. 

Before starting to drive open all doors, windows and, if available, the sun roof so that the accumulated heat can escape from the vehicle. 

Set the air conditioner to the lowest temperature setting, fully open the fan and activate the re-circulation button until a comfortable temperature is reached. When the air has cooled down as much as you want, you should set the air conditioner to the ideal temperature. The difference to the outside temperature should not be more than eight degrees, otherwise you can get a heat shock and circulatory problems when getting out.

Shortly before you reach your destination, you should switch off the air conditioning but let the fan continue to run so that no condensation on the evaporator can form. Otherwise, this could promote germs in the long-term and make it necessary to disinfect the evaporator in the interior. In addition, you can acclimatize and slowly get used to the outside temperature.
