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.
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate
is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open.
G WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow these components to cool down before touch-
ing them.
The handling characteristics of a laden vehi-
cle are dependent on the distribution of the
load within the vehicle. For this reason, you
should observe the following notes when
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
identification 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 com-
partment 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
materials appropriate for the weight and
size of the load. R
The maximum load capacity of the stowage
well under the cargo compartment floor is
55 lbs (25 kg). R
Secure the load 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. Please280
