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, 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.
GWARNING
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.
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 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 gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle occupants
and luggage/cargo.
Do not exceed the load limit or permitted gross
vehicle weight rating (GVWR) for your vehicle.
The gross load limit and the GVWR are specified
on the vehicle identification plate on the B-pillar
of the driver's door (
Ypage 364).
The load must also be distributed so that the
weight on each axle never exceeds the gross
axle weight rating (GAWR) for the front and rear
axles. The specifications for GVWR and GAWR are on the vehicle identification plate on the B-
pillar of the driver's door (
Ypage 364).
Observe the notes on loading the vehicle
(
Ypage 364).
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle. For this reason, you should
observe the following notes when transporting a
load:
RNever exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
RThe cargo compartment is the preferred place 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 upper
edge of the seat backrests.
RAlways place the load against the rear or frontseat backrests. Make sure that the seat
backrests are securely locked into place.
RAlways place the load behind unoccupied
seats if possible.
RUse the cargo tie-down rings and the parcel
nets to transport loads and luggage.
RUse cargo tie-down rings and fastening mate-
rials appropriate for the weight and size of theload.
RSecure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges for
protection.
Stowage spaces
Important safety notes
GWARNING
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.

RAlways stow objects in such a way that they
cannot be tossed about in these or similar
situations.
RAlways make sure that objects do not pro-
trude out of the stowage spaces, luggage
nets or stowage nets.
REnsure that closable stowage spaces are
shut before beginning your journey.
RAlways stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or large objects in
the cargo compartment.
