Comply with any legal requirements when towing and tow starting.
For technical reasons, vehicles with a discharged battery must not be tow-started.

Depending on the vehicle battery charge level, the drop in voltage can be large enough after just a few minutes that electrical consumers in the vehicle will no longer function, e.g. the hazard warning lights.
