Tank system malfunction! Please contact workshop
If the indicator lamp lights up and the message appears:
  • there is a malfunction in the tank system, or
  • on vehicles with a diesel engine, water may have collected in the fuel filter.
Drive to a qualified workshop without delay and have the fault rectified.
Caution!
Applies to vehicles with diesel engine: If poor-quality diesel fuel is used, it may be necessary to have the water separator1) on the fuel filter drained more frequently than is specified in the Service Schedule. This helps to prevent potential engine faults.
For the sake of the environment
Never pour fuel down drains or into the ground.
