Towing with the front axle raised rigid and articulated buses
Note:
The towing coupling must not be used for towing trailers.
Disconnect connector V 15-pin from the articulation angle control unit in the roof cross duct (22A01).
Caution:
Before you disconnect the power supply from the articulation angle control unit, switch the ignition starter switch to position 0.
Note:
For control unit locations, see legend in the roof cross duct.
Note:
Gear selection switch: press the “N” pushbutton.
Operation
The red warning lamp lights up because power is no longer being supplied to the articulation angle control unit.
Note:
In this condition, the articulation angle control unit cannot activate the bus stop brake automatically.
Caution:
Articulation protection is in emergency damping mode. Articulation protection and vehicle stabilisation functions are extremely limited. Vehicle handling characteristics will differ during the towing procedure. A suitable driving style must therefore be adopted.
Towing with the front axle raised (rigid and articulated buses)
Danger.
Only authorised specialists (recovery services) are permitted to tow away brokendown buses. The rules and regulations in the country concerned must be observed.
Caution:
Special measures are required in order to protect the transmission if the bus is to be towed: For safety reasons the propeller shaft must always be removed. The propeller shaft securing screws at the axle flange must be removed and those at the transmission flange secured against displacement.
Danger.
The ignition starter switch must not be switched to position 1 or 2 while the front axle is raised. The wheels on the driven axle may lock. Disregard for this warning could result in brake intervention
