Permobil K300 PS Junior User Manual page 32

Remove all non-crash-tested accessories and other loose objects from your
wheelchair and store them safely before you transport your wheelchair in a
motor vehicle. If you transport a wheelchair in a motor vehicle with non-
crash-tested accessories attached or with loose objects, the vehicle's occupants
could suffer bodily injury.
This is how you secure the wheelchair at its four tie-down points. Make sure
that the wheelchair is properly secured and that the wheelchair is not in
freewheel mode. Secure the wheelchair with straps at the tie-down points
at the front and rear. The tie-down points are marked with yellow labels .
