Car AC safety during heatwaves

Overview

Early in July, French automotive technicians cautioned drivers against turning on air‑conditioning immediately in a hot vehicle, noting that doing so could stress the engine and increase the risk of failure.

Later that month, German road safety and consumer groups issued detailed guidance for operating car air‑conditioning safely amid extreme temperatures. They advised keeping cabin temperatures between 22 °C and 25 °C, avoiding excessively cold settings, and briefly using maximum cooling with the recirculation mode before bringing in outside air. After cooling, they recommended opening doors to ventilate and steering clear of directing vents onto the face or body, as this can cause muscle tension, dry mucous membranes, and potential circulatory issues.
