Important safety notes G
WARNING
On its own, the safety net cannot secure or
restrain heavy objects, items of luggage and
heavy loads. You could be hit by an unsecured load during sudden changes in direction,
braking or in the event of an accident. There is an increased risk of injury or even fatal injury.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping over, e.g. by
using lashing material, even if you are using
the safety net.
It is important to use a safety net if you load
the vehicle with small objects above the seat backrests. For safety reasons, always use a
safety net when transporting a load.
Damaged safety nets can no longer fulfil their
protective function and must be replaced.
Visit a qualified specialist workshop.
Attaching and tightening the safety net You have two options for hooking in the safety
net:
R with luggage compartment enlargement:
the brackets are behind the B‑ pillar and the
lashing eyelets to tension the net are on the sides of the rear-compartment footwell.
R without luggage compartment enlarge-
ment: the brackets are behind the C-pillar
and the lashing eyelets to tension the net
are in the luggage compartment
(Y page 305). The safety net is located in the stowage space
under the luggage compartment floor
(Y page 308).
X Open both Velcro fasteners and remove the
safety net.
