If th eve hicle being tow star ted or towed
aw ay is heavier than the permissible gross
we ight of your vehicle, thefo llowing situa‐
tions may arise:
R The towing eyemay become de tach ed.
R The vehicle/trailer combination may even
tip ove r. #
Before tow starting or towing away a
ve hicle, check that it does not exceed
th e permissible gross weight. If a
vehicle must be tow- star ted or towe daw ay,
its permissible gross mass must not exceed the
permissible gross mass of theto wing vehicle. #
