WARNING!
Stop the engine and apply the parking
brake when loading or unloading long
objects.
A loose object weighing 20 kg can, in a
frontal collision at a speed of 50 km/h,
carry the impact of an item weighing
1000 kg.
Always secure the load. During heavy
braking the load may otherwise shift,
causing personal injury.
