Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Engine compartment Automatic transmission fluid level The transmission has a permanent fill of automatic transmission fluid. Regular automatic transmission fluid level checks and changes are not required. For this reason the dipstick is omitted. If you notice fluid leaks or gear shifting malfunctions, have your authorized Mercedes-Benz Light Truck Center check the transmission fluid level. Engine oil consumption Engine oil consumption checks should only be made after the break-in period. During the break-in period, higher oil consumption may be noticed and is normal. Frequent driving at high engine speeds results in increased consumption. 234 Coolant level P20.30-0241-20 To check the coolant level, the vehicle must be parked on level ground and the engine stopped. Check coolant level only when coolant is cold. The coolant level should reach the COLD LEVEL mark in the reservoir.
