Introduction to the topic
When towing, observe the legal regulations.
A vehicle with a discharged battery must not be
towed for technical reasons.
For technical reasons, the vehicle must not be
started. Instead, use the starting aid

not be towed for technical reasons unless it
can be ensured that the transmission is in the

switched off and the ignition switched on, the
vehicle battery is discharged depending on the
charge of the vehicle battery, after only a few
minutes the voltage drop may be so great that
no electrical consumers inside the vehicle, e.g.
warning lights, will function.
