Overview

• Experts advise opening all doors or windows before starting to let out built-up heat and then closing them before switching on air conditioning.
• Activating the recirculation function immediately cuts off incoming warm air to speed up the cooling process.
• Drivers should limit cabin temperatures to no more than six degrees Celsius below the outside heat and aim for 22–25 °C to avoid circulatory stress.
• Using air conditioning on trips under 10 minutes increases wear on the compressor and seals and can raise fuel consumption by up to 4 L per 100 km.
• Turning off the cooling function a few minutes before arrival while keeping the fan running helps dry the system and prevents bacterial growth.
