Stowage and features

Useful information
i This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops ( Y
page 29).
Stowage areas
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 gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle occu-
pants 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
( Y
page 416).
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
( Y
page 416).
Observe the notes on loading the vehicle
( Y
page 416).
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). 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.340
Stowage areas
Stowage and features

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
Secure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges
for protection.
Stowage spaces
Important safety notes
G WARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants.
There is a risk of injury, particularly in the
event of sudden braking or a sudden change
in direction. R
Always stow objects so that they cannot be
thrown around in such situations. R
Always make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets. R
Close the lockable stowage spaces while
driving. R
Stow and secure objects that are heavy,
hard, pointy, sharp-edged, fragile or too
large in the cargo compartment.
Observe the loading guidelines ( Y
page 340).

G WARNING
Vehicles with the Occupant Classification
System (OCS):
If the gross weight of the objects in the stow-
age net on the back of the front-passenger
seat is greater than 4.4 lb (2 kg), OCS cannot
correctly assess the occupant's weight cate-
gory. The front-passenger front air bag could
deploy without cause, or may fail to deploy in
the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always observe the permissible gross weight
of 4.4 lb (2 kg). Stow and secure heavy
objects in the cargo compartment.

spaces ( Y
page 341).
Through-loading facility in the rear If objects or loads are not secured when being
transported in the through-loading facility,
they could slip or be thrown around and
thereby hit vehicle occupants.
Observe the loading guidelines ( Y
page 340)
and the safety notes regarding stowage
spaces ( Y
page 341).
The through-loading facility is opened from
the cargo compartment. X
Release the seat backrests in the second
row of seats and tilt them in the cargo/load
position ( Y
