side, the tail lamps may be blocked from view.
Other road users may then fail to see you and
crash into your vehicle. Additionally, secure
your vehicle using a warning lamp or a warn-
ing triangle.
Do not drive with the spare wheel bracket fol-
ded out.
Make sure that the spare wheel bracket is
closed correctly.
Otherwise, the freely moving spare wheel
bracket could injure people or cause an acci-
dent.
