General notes
Some systems carry out a self-diagnosis when the ignition is switched on. Several warning and
indicator lamps can thereby temporarily light up or flash. This behaviour is non-critical. These
warning and indicator lamps only indicate a malfunction if they light up or flash after the engine is started or during a journey. Wa

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, especially when braking or abruptly changing directions.
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. Exhaust
gases can enter the vehicle interior if the boot
lid is open when the engine is running, espe-
cially if the vehicle is in motion. There is a risk of poisoning.
Always switch off the engine before opening
the boot lid. Never drive with the boot lid
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 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 weight or the permissible axle loads
for the vehicle (including occupants).
R the boot is the preferred place to store
objects.
R position heavy loads as far forwards as pos-
sible and as low down in the boot 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 lashing eyelets and the luggage nets
to transport loads and luggage.
R only use lashing eyelets and fastening com-
ponents that are suitable for the weight and
size of the load.
R secure the load with sufficiently strong and
wear-resistant lashing material. Pad sharp
edges for protection.
i Load restraints are available at any qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. Stowage compartments
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 boot.
Observe the loading guidelines (Y page 272).272

WARNING
If you exceed the maximum permitted load of the stowage compartment, the cover is
unable to restrain the objects. Objects may be
thrown out of the stowage compartment and
hit vehicle occupants as a result. There is a
risk of injury, particularly in the event of sud-
den braking or a sudden change in direction.
Always observe the maximum load of the
stowage compartment. Stow and secure
heavy objects in the boot.
The maximum permissible load of the stowage
compartment is 1.5 kg. X
To open: pull handle :up and fold cover ;
forwards.
i On vehicles with a fire extinguisher instead
of a stowage compartment, the fire extin-
guisher is installed under the driver's seat. Stowage nets
Stowage nets are located in the front-passenger footwell and on the left- and right-hand sides of
the boot.
Observe the loading guidelines (Y page 272)
