Setting the vehicle level
& WARNING Risk of accident because
vehicle level is too high

The vehicle can drift outwards, for example,

Always choose a vehicle level which is
#
suited to the driving style and the road
surface conditions.
& WARNING Risk of entrapment from vehi‐
cle lowering
When lowering the vehicle, other people
could become trapped if their limbs are
between the vehicle body and the tyres or
underneath the vehicle.
Make sure no one is underneath the
#
vehicle or in the immediate vicinity of
