Loading guidelines
GWARNING
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,
particularly in the event of sudden braking
or a sudden 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.
GDANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Exhaust gases can enter the vehicle interior
if the tailgate is open while the engine is
running, especially if the vehicle is in
motion. There is a risk of poisoning.
Always switch off the engine before opening
the tailgate. Never drive with the tailgate
open.
GWARNING
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 burns.
Always be particularly careful and supervise
children closely around the exhaust pipe and
the exhaust pipe trims. Allow these compo-
nents to cool down before touching them.
The handling characteristics of a laden vehicleare dependent on the distribution of the loadwithin the vehicle.
Observe the following notes when loading andtransporting a load:
RNever exceed the maximum permissiblegross vehicle mass or the gross axle weightrating for the vehicle (including occupants).The values are specified on the vehicle iden-
tification plate on the B-pillar of the driver'sdoor.
RThe cargo compartment is the preferredplace to carry objects.
RPosition heavy loads as far forward as possi-ble and as low down in the cargo compart-ment as possible.
RThe load must not protrude above the upperedge of the seat backrests.
RAlways place the load against the rear orfront seat backrests. Make sure that theseat backrests are securely locked intoplace.
RAlways place the load behind unoccupiedseats if possible.
RUse the cargo tie-down rings and the parcelnets to transport loads and luggage.
RUse cargo tie-down rings and fasteningmaterials appropriate for the weight andsize of the load.
RThe maximum load capacity of the stowagewell under the cargo compartment floor is55 lbs(25 kg).
RSecure the load with sufficiently strong andwear-resistant tie-downs. Pad sharp edgesfor protection.
!Do not position the load on one part of thefolding cargo compartment floor only. Themaximum load capacity of the folding cargocompartment floor is 220 lbs(100 kg). Dis-tribute theweight evenly to avoid damagingthe cargo compartment floor. Place a solidboard under the load if necessary. Pleasenote that the load on the cargo compart-ment floor will be increased when the loadis lashed down.

If you transport objects in the vehicle inte-
rior and these are not adequately secured,
they could slip or be flung around and
thereby strike vehicle occupants. In addi-
tion, 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, particularly in the event of sharp
braking or sudden changes of direction.
RAlways stow objects in such a way that
they cannot be tossed about in these or
similar situations.
