ASSYST Service Schedule — Malaysia Notes
Modern Mercedes-Benz models use ASSYST Plus — an adaptive service indicator that calculates intervals based on driving style, engine load, and temperature. In Malaysian city driving, Service A typically appears every 10,000–13,000 km. Critical items not triggered by ASSYST: 9G-Tronic ATF (do every 40,000–60,000 km manually), brake fluid (every 2 years regardless), and coolant (every 3 years or 60,000 km). Never ignore the ASSYST indicator — a missed service can trigger a cascading failure on the timing chain tensioner.
