What Do You Know the High Low Temperatures Inside Your Car

The driver must rely on the air conditioning – or heating – to always be alert at the wheel.

In these days of extreme temperatures, in which the thermometer can fall to zero at dawn, and at noon rise to 25 ° C, several studies have been able to determine that the temperature conditions inside the interior of a vehicle directly influence the capacity and behavior of the driver.

It shows that when the temperature inside the interior of the vehicle is greater than 24 ° C, driving errors and accidents increased, and more than 35 ° C the driver has symptoms similar to those he would have with a breathalyzer of 0.5 milligrams in blood. Also, too cold produces limb seizure and slow reactions.

Driving temperature

The heat that a driver supports defined as that which depends on the outside temperature. The surface of the car exposed to solar radiation, the heat that the occupants give off, as well as the type and color of the clothes it carries.

This cabin temperature can control by heating and air conditioning. Both went from being considered a luxury to becoming an important active safety system because together it is an integrated system that provides cooling, heating, defrosting, elimination of fogging, air filtration and humidity control for the comfort of the occupants.

Driving a vehicle with elevated temperature in the passenger compartment induces fatigue because by having to regulate the body temperature, the brain slows down, that is, some reactions considerably reduced.

Besides, heat is a potentiating factor, and this means that it increases any alteration or symptom that the driver may have. For example, if he is sleepy, he will have more heat.

Additionally, driving attention, information assimilation, and visual acuity reduced, reaction time, and aggressiveness are increased, especially if the heat maintained for a long time.

Research has shown that 30 ° C driving failures increased by 20%, and the time the driver was slow to react increased by 22% to pass 21 ° C to 27 ° C. At the same time, at 90 km / h and exposed to high temperature. An average driver reaches a distance of 41 meters before operating the brake pedal while driving with an optimum passenger compartment temperature. I would perform this action after having traveled 25 meters.

When there is a lot of humidity (rain product or very low temperatures), there are also visibility problems, due to fogging of the vehicle’s glass, this is corrected using the air conditioning system since it dehumidifies the interior of the cabin.

Another important point is that of temperature control management

A vehicle equipped with an air conditioning system equips with a panel from which all heating, air conditioning, defrosting, and ventilation functions can control.

Likewise, the vehicle has a series of ducts that enter or extract air from the passenger compartment, which end up in grilles located in such a way that they meet all the needs of the passenger compartment.

So the easiest way to remove the heat from the cabin is to turn on the air conditioner and with the recirculation button activated until the thermal sensation is pleasant.


Some complain that the air conditioning dries the air too much and affects health. For those people sensitive to the natural dryness that the A / C leaves, tell them that the system can shut down at any time.

On the contrary, when the temperature is too cold, it is convenient to turn on the heating by turning the temperature knob to red and direct the air jets at the feet so that they do not seize. Hot air, as it tends to rise, will heat the rest of the vehicle.

Finally, when there is heavy rain, shallow temperature, or the environment is very humid, the fogging of the glass is presented. To quickly eliminate this phenomenon, you must turn on the air conditioner to the maximum, verify that it is in “recirculation” mode and blow it to the panoramic.
