Loading guidelines
G
WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle.
Observe the following notes on loading and
transporting a load:
R Never exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
The values are specified on the vehicle iden-
tification plate on the B-pillar of the driver's
door.
R The cargo compartment is the preferred place
to carry objects.
R Position heavy loads as far forwards as pos-
sible and as low down in the cargo compart-
ment as possible.
R The load must not protrude above the upper
edge of the seat backrests.
R Always place the load against the rear or front
seat backrests. Make sure that the seat
backrests are securely locked into place.
R Always place the load behind unoccupied
seats if possible.
R Use the cargo tie-down rings and the parcel
nets to transport loads and luggage.
R Use cargo tie-down rings and fastening mate-
rials appropriate for the weight and size of the load.
R Hook in the cargo net when loading.
R The maximum load capacity of the stowage
well under the cargo compartment floor is
55 lbs (25 kg).
R Secure the lo ad with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges for protection. !
Do not position the load on one part of the
folding cargo compartment floor only. The
maximum load capacity of the folding cargo
compartment floor is 220 lbs (100 kg). Dis-
tribute the weight evenly to avoid damaging
the cargo compartment floor. Place a solid
board under the load if necessary. Please
note that the load on the cargo compartment floor will be increased when the load is lashed
down. Stowage areas
Stowage spaces
Important safety notes G
WARNING
If you transport objects in the vehicle interior and these are not adequately secured, they
could slip or be flung around and thereby
strike vehicle occupants. In addition, cup
holders, open stowage spaces and mobile
phone brackets may not always be able to
hold the objects placed in them in the event of an accident. There is a risk of injury, particu-
larly in the event of sharp braking or sudden
changes of direction.
R Always stow objects in such a way that they
cannot be tossed about in these or similar
situations.
R Always make sure that objects do not pro-
trude out of the stowage spaces, luggage
nets or stowage nets.
R Ensure that closable stowage spaces are
shut before beginning your journey.
R Always stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or large objects in
the cargo compartment.

Important safety notes G
WARNING
On its own, the cargo compartment cover
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.
! When removing and installing the cargo
compartment cover, ensure that its end caps do not scrape the light-colored parts of the
vehicle.
