This chapter contains information on the following subjects:
→ Notes on tow-starting
→ Notes on towing→ Fitting the front towing eye
→ Fitting the rear towing eye→ Driving notes on towing
Observe any legal requirements when towing or tow-starting.
For technical reasons, vehicles with a discharged battery must not be tow-started.
Vehicles with Keyless Access must only be towed with the ignition switched on.
Towing a vehicle when the engine is switched off and the ignition is switched on discharges the vehicle battery. 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. In vehicles with Keyless Access, the steering wheel can lock .
