Specifications:
Extensive listing of all relevant technical specifications, including torque values, clearances, fluid capacities, and electrical parameters.
Oil Change:
Typically every 15,000 km or 12 months (refer to manual for specific interval based on driving conditions and oil type).
Major Service:
Scheduled around 60,000 km or 4 years, including spark plugs, transmission fluid change (automatic), coolant replacement, etc. (detailed schedule in manual).
Engine Oil:
MB 229.3 or MB 229.5 compliant synthetic oil, viscosity SAE 0W-30 or 5W-40 (refer to manual for exact recommendation).
Coolant:
MB 325.0 (Antifreeze/Coolant concentrate) mixed with distilled water (typically 50/50 ratio).
