GWARNING
The Top Tether anchorages cannot secure a
load. If you secure a load with the Top Tether
anchorages, the Top Tether anchorages could be pulled out during braking, abrupt changes
in direction or in the event of an accident. The load could slip, tip over or be flung around and
thereby hit vehicle occupants. There is a risk
of injury.
Only use the cargo tie down rings when secur- ing a load.
Observe the following notes on securing
loads:
R Observe the loading guidelines
(Y page 274).
R Secure the load using the cargo tie-down
rings.
R Distribute the load on the cargo tie-down
rings evenly.
R Do not use elastic straps or nets to secure
a load, as these are only intended as an
anti-slip protection for light loads.
R Do not route tie-downs across sharp edges
or corners.
R Pad sharp edges for protection.
There are four cargo tie-down rings in the
cargo compartment and two in the rear-com- partment footwells 11

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 tie downs, even if you are using the
cargo compartment cover.
! When loading the vehicle, make sure that
you do not stack the load in the cargo com-
partment higher than the lower edge of the side windows. Do not place heavy objects
on top of the cargo compartment cover.
The cargo compartment cover is located
behind the rear bench seat backrest.
