Stowage areas
Loading guidelines
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid is open when 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 trunk lid. Never drive with the trunk lid
open.
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
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 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
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 iden- tification plate on the B-pillar of the driver's
door. R
The trunk is the preferred place to carry
objects. R
Position heavy loads as far forwards as pos-
sible and as low down in the trunk as possible. R
The load must not protrude above the upper
edge of the seat backrests. R
Always place the load behind unoccupied
seats if possible. 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. In
addition, cupholders, open stowage spaces
and mobile phone brackets cannot always
retain all objects they contain. 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 before
starting a journey. R
Always stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or bulky objects in
the trunk.
Observe the loading guidelines ( Y
