G WARNING
With tire pressures which are too low, there is a risk of the
following hazards:
R they may burst, especially as the load and vehicle speed
increase.
R they may wear
excessively and/or
unevenly, which may greatly
impair tire traction.
R the driving characteristics, as well as steering and braking, may
be greatly impaired.
There is a risk of an accident.

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment 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-

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,
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. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide.
If the tailgate
is open when the engine is running,
particularly 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
tailgate. Never drive with the tailgate open.
The gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle
occupants and luggage/cargo.
The gross load limit and the gross vehicle
weight rating (GVWR) for your vehicle must
never be exceeded. 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 339).
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 339).
Further information can be found in the
"Loading the vehicle" section ( Y page 339).
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:
R The cargo compartment is the preferred
place to carry objects.
R Position heavy loads as far forwards as
possible and as low down in the cargo
compartment 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 Hook in the cargo net (if installed) when
loading.
R Secure the load with sufficiently strong and
wear-resistant tie-downs. pad sharp edges
for protection.270

WARNING
If objects in the passenger compartment are

R Always stow objects so that
they cannot be
thrown around in such situations.
R Always make sure that objects do not
protrude 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.

WARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold
forwards, e.g. when braking suddenly

Cargo tie-down rings G
WARNING
The Top Tether anchorages cannot secure a
load. If you secure a
load with the Top Tether
anchorages, the Top Tether anchorages could
be pulled out during braking, abrupt changes
in direction or in the event of an accident. The
load could slip, tip over or be flung around and
thereby hit vehicle occupants. There is a risk
of injury. Only use the cargo tie down rings when
securing a load.
Observe the following notes on securing
loads:
R Observe the loading guidelines
(Y page 270).
R Secure the load using the cargo tie-down
rings.
R Distribute the load on the cargo tie down
rings evenly.
R Do not use elastic straps
or nets to secure
a load, as these are only intended as an
anti-slip protection for light loads.
R Do not route tie-downs across sharp edges
or corners.
R Pad sharp edges for protection.

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
compartment higher than the lower edge of
the side windows. Do not place heavy
objects on top of the cargo compartment
cover.
The cargo compartment cover is located
behind the rear bench seat backrest.

Important safety notes G
WARNING
On its own, the cargo net 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 net.
It is important to use a cargo net if you load
the vehicle with small objects
above the seat
backrests. For safety reasons, always use a
cargo net when transporting loads.
Preparing the cargo net The cargo net can be used in two different
positions (behind the B-pillar or the C-pillar).
