Mercedes-Benz CLS — ASSYST 保养灯
CLS ASSYST Plus Reset
- ASSYST Plus adaptive interval — oil, ATF, brake fluid counters independent
- Reset via XENTRY or instrument cluster after each service — Malaysia interval typically 15,000–20,000 km
Mercedes ASSYST Service Indicator — 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.
