Please turn on the electrics, if not already done.

On the instrument panel the following light are on:

• (1) General error
• (2) Battery used
• (3) Parking brake attached
• (4) ABS
• (5) Pressure for kneeling function too low

The ABS is a technical system that provides better maneuverability and directional stability during braking. It also shortens braking distance on wet roads by controlling the wheel slip.

In addition to the ABS the ASR (traction control) acts by preventing the wheels from spinning. Both systems are installed in that bus.

Start the engine. Once the engine is running, the compressed air tanks are charged and available for further exercises.
