Please observe national guidelines concerning official approval of extensions.
Any alteration or conversion of the tow bar is prohibited and will result in the cancellation of the type approval.
Remove insulating compound or underseal (if present) from the vehicle's mating surfaces for the tow bar.
The tow bar is designed for towing trailers fitted with ball couplings and for use with load-bearing implements approved for attachment to the tow bar. Any other use is prohibited.
