235. Air conditioning
Air conditioning helps control the temperature and humidity inside a vehicle and can improve comfort and visibility. In hot weather it cools the passenger compartment, while in damp conditions it can help remove moisture from the air and clear mist from the windows more quickly. Drivers should use the system in a way that keeps the interior comfortable without creating large temperature differences, and the system should be maintained so that it continues to work effectively.

Is air conditioning mandatory in cars in Belgium?
No. Air conditioning itself is not generally mandatory equipment for passenger cars in Belgium. However, the vehicle must still provide adequate visibility and comply with applicable technical requirements.
Is the demisting system important in Belgium?
Yes. A functioning demisting and defrosting system is important for maintaining clear visibility through the windscreen and forms part of the applicable vehicle safety requirements.
Is the demisting system checked during the Belgian technical inspection?
Yes. European roadworthiness rules used as the basis for Belgian technical inspection include checks of the windscreen demisting system. A system that does not operate correctly can be recorded as a defect.
Does the air-conditioning system itself have to work for the Belgian technical inspection?
The periodic technical inspection focuses on roadworthiness and safety systems. The air-conditioning system itself is not generally treated as a mandatory comfort feature, although related systems such as demisting and ventilation may be relevant to visibility and safety.
Can air conditioning help improve visibility in Belgium?
Yes. Using air conditioning together with the vehicle's ventilation system can remove moisture from the air and help clear misted windows, which is especially useful in damp or cold weather.
