Additional Notes
- The Mercedes-Benz G-Class W463B (EU) transfer case holds 2.8 liters of fluid across all four variants covered in the specifications: the G 350 d, G 400 d, G 500, and G 63 AMG.
- A 2.8-liter transfer case fill is a moderately sized capacity, consistent with a two-speed transfer case unit of the type typically found in full-size body-on-frame or ladder-frame SUVs designed for off-road use.
- The G 350 d (463.349) and G 400 d (463.350) are diesel-powered variants, yet both share the identical 2.8-liter transfer case capacity and 120,000 km change interval as the petrol-powered G 500 and G 63 AMG.
- The 120,000 km fluid change interval applies under normal use conditions for all four variants, meaning the interval is not intended for severe-duty or off-road-intensive driving cycles.
- The G 63 AMG (463.277), despite carrying AMG performance designation and a higher-output engine, carries no differentiation in transfer case fluid capacity or service interval relative to the standard G 500 (463.260).
- A 120,000 km change interval for transfer case fluid is relatively extended, reflecting a sealed or semi-sealed unit design where fluid degradation under normal conditions is considered gradual enough to support long drain periods.
