Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 27). Loading guidelines
G
WARNING
Secure and position the load as described in
the loading guidelines.
Otherwise, vehicle occupants could
be injured by the load being thrown around in
the event of sharp braking, a sudden change
in direction or an accident.
You will find further information in the "Secur-
ing a load" section.
Even if you follow all the loading guidelines,
the load will increase the risk of injury in the
event of an accident. G
WARNING
Keep the tailgate closed when the engine is
running. Otherwise, you could be poisoned by
exhaust fumes entering the vehicle.
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 when transporting a load, never exceed the
maximum permissible gross vehicle weight
or the permissible axle loads for the vehicle
(including occupants).
R position heavy loads as far forwards as pos-
sible and as low down in the load compart-
ment 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 hook in the safety net when loading.
R always place the load behind unoccupied
seats if possible.
R secure the load with sufficiently strong and
wear-resistant lashing material. Pad sharp
edges for protection.
i Load restraints are available at any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre. Stowage areas

WARNING
The stowage compartments must be closed
when items are stored in them. Luggage nets

injured by objects being thrown around if you:
R brake sharply
R change direction suddenly
R are involved in an accident
Please observe the loading guidelines.

Bag hook G
WARNING
Only hang light loads on the bag holders. Do
not use them to transport heavy, sharp-edged
or fragile objects. When braking sharply,
changing direction quickly or in the event of
an accident, the bag hooks will not secure the
items sufficiently. This could result in injury to
yourself or others.
! The bag hook can bear a maximum load
of 5 kg. Do not use it to secure a load.
There is one bag hook on the left side wall in
the luggage compartment and there are two hooks on the right and left of the lower D-pillar
trim.
Luggage compartment cover
Important safety notes G
WARNING
The luggage compartment cover is not a
restraint system. Secure the load under the
luggage compartment cover by suitable
means. Make sure that the luggage compart-
ment cover is engaged securely. If luggage is
not sufficiently secured, it can be thrown over
the backrest into the passenger compart-
ment, for instance during heavy braking, sud-
den changes of direction or in the event of an
accident. You could cause an accident or
cause injury to yourself and others.
! When loading the vehicle, make sure that
you do not stack the load in the luggage
compartment higher than the lower edge of
the side windows. Do not place heavy
objects on top of the luggage compartment
cover.
The luggage compartment cover is located
behind the rear bench seat backrest.
i You can fold up the solid section of the
luggage compartment cover approximately
45° to facilitate loading the luggage com-
partment. 300

denly or are involved in an accident, and could
cause you an injury.
