Anti-lock brakes
(option)
This indicator light is connected if the bus has anti-lock
brakes, ABS.
The ABS-system is not at fault when the indicator light
comes on when the starter key is turned to drive position.
The indicator light will go out after a couple of seconds
when the system has finished performing its tests.
If the light does not come on when the starter key is turned to
the ignition position, then there is something wrong with the
indicator light or its power supply.
If the light does not go out, or if it comes on again during
driving, then a fault has occurred in the ABS-system. See
also below under ASR.
The bus can be driven even if the ABS-light comes on while
driving. The systems circuits are diagonally connected to
the wheels. This means if a fault should occur on the ABS-
system, the operation of the diagonal circuit at fault will be
disconnected. The normal braking function on the faulty cir-
cuit is however fully functional and works like a normal
brake circuit when applied.
Anti-spin regulation
(option)
Anti-spin regulation, ASR, prevents the drive wheels from
spinning when starting and when driving in slippery condi-
tions. If wheel spin occurs, the spinning drive wheel is
brought to a halt and/or the throttle speed is reduced, all
depending on the driving conditions. ASR is a fully automat-
ic system integrated with ABS-brakes and the engine con-
trol system.
There are no warning lights, controls or switches for the
ASR-system but due to the fact that the ASR- and ABS-sys-
tems are integrated, the indicator light for the ABS also indi-
cates electrical faults in the ASR-system.
Instruments and controls

driving:
