Now we have already tried some functions in the off state of the bus and have not yet paid attention to the manometers. Meanwhile, the air pressure decreased so much, that the pressure warning indicator came up. The white pointer indicates a dangerously low pressure.

Please use the brake by pressing [Num 2] once and thereby look at the warning pointer.

The only way to replenish the compressed air is to start the engine. To start and stop engine you can also hold down the [M] button. While the engine is running, the air is continuously replenished automatically in all tanks.

Please start the engine and wait for a sufficient air pressure level.
