Air-pressure gauge
Gauge1 indicates the pressure in the pressure chamber for
the first axle brake circuit and gauge 2 the pressure in the
pressure chamber for the second axle brake circuit. While
driving, the indicators should be above the red zone.
Articulated buses have a third air-pressure gauge which
shows the pressure in the pressure chamber for the trailer.
This gauge is located in the group of instruments on the
right of the steering wheel.
Low air pressure, footbrake
The warning light is connected to both brake circuits and
comes on if the air-pressure in either of the circuits drops
below 490 kPa (4.9 kp/cm
2
).
Never begin driving as long as the warning light is on.
If the light comes on while driving: stop the engine immedi-
ately and investigate the cause.
