Mercedes-Benz GLC — ASSYST 保养灯

Both GLC generations use ASSYST Plus. City driving in Malaysia triggers Service A every 10,000–13,000 km. Critical reminder: ASSYST does NOT track 9G-Tronic ATF. Always set your own 20,000 km ATF reminder — this is the single most missed service on GLC in Malaysia.

The ASSYST Plus service indicator on modern Mercedes-Benz calculates remaining oil life based on driving conditions — not a fixed mileage. In Malaysian city driving, Service A typically appears every 10,000–13,000 km. The indicator must be reset after every service using a diagnostic tool — a simple trip reset does NOT reset ASSYST. Never ignore ASSYST warnings: a missed Service A means driving with degraded oil and a known-live timing chain tensioner concern. Items ASSYST does NOT remind you about: 9G-Tronic ATF, coolant, and some brake inspections — manage these manually.
