Towing
Vehicles involved in an accident:
왘 Before raising the vehicle, check the connections between the frame sections and between the frame and
the axle.
왘 On air-sprung vehicles: Set air suspension (on the raised axle) to "Lower".
왘 If the air spring bellows on a rolling axle are defective, ensure adequate clearance and tow at a maximum of
10 km/h.
왘 Fold up or detach the underride guard if necessary.
Additionally for semitrailer tractors with semitrailer:
왘 Make sure there is sufficient clearance between the semitrailer tractor and the semitrailer, particularly when
cornering and when starting to drive up steep slopes.
왘 Deactivate acceleration skid control (ASR), see page 103.
왘 Remove the propeller shaft to the rolling axles.
왘 When towing entire combinations, route an ABS cable from the towing vehicle to the trailer or semitrailer
(5-pin).
Overview of towing options
Risk of accident G
Trailer/semitrailer with ABS/EAB:
When towing entire truck/trailer combinations with braked trailer and electronic trailer brake, there is a
danger of uncontrolled braking of the trailer/semitrailer.
This can cause the trailer/semitrailer to lose lateral stability and break away.
Connect the towing vehicle and the trailer/semitrailer with an ABS cable (5-pin).
Retrofit an ABS socket on the towing vehicle if necessary.
