Car in summer: beware of heat death






You should observe these tips so that your car does not become a deadly heat trap! After all, you don’t have to drive a Tesla to save animals or small children from heat death in the car.

Years ago, Tesla introduced a literally cool feature for its vehicles like the Model 3: the dog mode. This function is intended to save animals in the Tesla from overheating. A test by the ADAC showed how useful Tesla’s dog mode is. Not only for dogs, but also for small children! Right now before the start of the travel season.

Because in a car standing in the blazing sun, the interior temperature can rise to well over 50 degrees. A car parked in the sun can be life-threatening for children or animals left behind. A driver, on the other hand, who immediately drives off in such a heated car is not able to concentrate – the risk of an accident increases.

The interior of the car heats up very quickly - regardless of whether the windows are closed or open.

The ADAC also refutes two myths related to the heating of cars with its test:

  • It’s almost useless if you leave the side windows of a parked car open a crack. According to the ADAC, an examination of identical vehicles with different window openings at an outside temperature of 28 degrees Celsius produced almost the same picture: “If the windows remained closed, 38 degrees were measured after ten minutes and even 45 degrees after 20 minutes. If two windows were slightly open, the Values ​​are still 36 and 42 degrees Celsius (after ten and 20 minutes respectively). After an hour in the blazing sun, the temperature display climbed well over the 50 degree mark.”

  • The car color has no influence on the heat development in the car: the ADAC experts found no difference in the heat development depending on the paint color. The interior temperature is not only life-threatening in dark vehicles, but also in vehicles with light paintwork.

According to the ADAC, tinted windows (which can also be retrofitted with the appropriate film) or heat-insulating glazing help to lower the interior temperature: “Because the window surfaces have the largest share in the development of heat in the car. Their size, the angle of incidence of the sun and the color of the Indoors have a strong influence on warming. Films on the windows also protect by reflecting the sunlight that provides heat.”

The ADAC warns in this context: Only the windscreen protects against UV-A and UV-B radiation as far as possible – the side windows, however, allow the UV-A radiation to pass.

ADAC tips on how to brave the heat in the car:

  • Open the doors and sunroof of the vehicle that has been heated by the sun and ventilate well

  • Close the windows and sunroof when the air conditioning starts to work

  • Set the ventilation to the highest level at the start of the journey

  • Put a sun protection mat on the windshield when parking

  • Put a towel on leather seats – the cover heats up a lot.

Even better: you do without leather seats entirely. Cloth seats don’t heat up nearly as much as leather. And they don’t get nearly as cold as leather seats in winter either.
