if the engine is running and the tailgate is
open. This could poison you. Therefore, you
should make sure that the tailgate is always
closed when the engine is running.

when opened. Therefore, make sure that
there is sufficient clearance above and
behind the tailgate.

R opened and closed* automatically from
inside (Y page 62) Spare wheel bracket*

Risk of accident
While the spare wheel bracket is folded to the
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.

spare wheel bracket in an automatic car
wash.
