Cabin Filter — Critical in Malaysia
The cabin filter sits between the blower and the evaporator. A blocked filter restricts airflow, forcing the blower motor harder and reducing cooling efficiency. In Malaysia's haze season, a clean activated-carbon filter also absorbs PM2.5 particles. Replace every 15,000 km — not the European 30,000 km interval.
