Mercedes-Benz GLA ASSYST Plus Service Indicator Malaysia — H247
H247 GLA ASSYST Plus adapts to your actual driving. Urban KL driving triggers more frequent service. Service A and B explained — and what to do if the indicator displays 'Workshop Visit Required'.

ASSYST Plus on GLA — same system as A-Class and CLA. Service A = oil change. Service B = oil + filter + brake fluid + spark plugs + full inspection. Cap at 12,000 km in Malaysian conditions. Reset via XENTRY or instrument cluster after service.
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.
