Open flap (1), remove sealing cap (2) from filler valve (3).

Note:

Due to variations in how the coupling is operated, the refuelling procedure may differ from filling station to filling station. Observe the general safety precautions on-site at the filling station concerned. Once started, the refuelling process runs and ends automatically. Operation

Note:

Before the refuelling coupling of the filler hose is attached, check filler valve (3) for damage and contamination.

Note:

Once flap (1) is opened, proximity switch (5) inhibits engine starting.

Note:

The current system pressure of the compressed-gas reservoirs can be seen on pressure gauge (4).

Function of the accident data recorder (ADR) (option)

The accident data recorder (ADR) is a system for detecting and recording accidents and driving events, e.g. pulling away against a kerb or sudden braking.

The accident data recorder (ADR) is activated automatically when the ignition is switched on.

Note:

The accident data recorder (ADR) remains active for 3 days after the ignition has been switched off and continues to register all vehicle movements (e.g. parking collisions).

Operation

M54_00-1502-71

As soon as the ignition is switched on, the accident data recorder (ADR) carries out a self-test and provides audible notification of the current operating status or the presence of a hardware fault.

Note:

A brief, one-off audible signal (buzzer in the control panel) (4) indicates that the accident data recorder (ADR) is ready for operation.

Note:

Indicator lamp (2) lighting up and a brief, one-off buzzing sound means that at least one event is stored.

Note:

A sequence of four long buzzes indicates that the accident data recorder (ADR) has detected a parking collision. Check your vehicle for damage.

Note:

Eight short buzzes mean that the memory of the accident data recorder (ADR) is almost full to capacity. Export the events and have the memory cleared.

Note:

Ten short buzzes mean that the accident data recorder (ADR) has malfunctioned. Similarly, a malfunction is present if no signal sounds. Following any critical traffic or accident situation, it is possible to record an entry manually.

Note:

When pushbutton (1) is pressed following an accident, the event (approximately 43 seconds before, during and after the accident) is stored and remains write-protected for an extended period.
