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

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 even tofsharp 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 boot lid/tailgate closed while the
vehicle is in operation. Otherwise, exhaust
fumes could enter the vehicle interior and poi-
son you.
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 boot/luggage
compartmenta s 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 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 compartments
Important safety notes G
WARNING
The stowage compartments must be closed
when items are stored in them. Luggage nets
are not designed to secure heavy items of
luggage.
You or other vehicle occupants could be
injured by objects being thrown around if you:
R brake sharply
R change direction suddenly
R are involved in an accident
Sharp-edged and fragile objects must not be
placed in the luggage net.
Do not place hard objects in the map pockets.
Objects must not protrude from the map
pockets. 310

Important safety notes G
WARNING
Observe the legal requirements of the country
in which you are currently driving regarding
operating mobile communications equipment
in a vehicle.
If it is permitted by law to operate communi-
cations equipment while the vehicle is in
motion, you must only do so if the traffic sit-
uatio npermits .Otherwise, you could be dis-
tracted from the traffic conditions, cause an
accident and injure yourself and others.
Two-way radios and fa xequipment used with-
out low-reflection exterior aerials can inter-
fere with the vehicle's electronics and thereby
jeopardise the operating safety of the vehicle
and your safety. Therefore, you must only use
this equipment if it is correctly connected to
a separate reflection-free exterior aerial. G
WARNING
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior aerial takes
into account current scientific discussions
relating to the possible health risk posed by
electromagnetic fields. Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R
optimal mobile phone reception quality in
the vehicle
R mutual influences between the vehicle
electronics and mobile phones are mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by a wireless device to the exterior.
R the field strength in the vehicle interior is
lower than in a vehicle that does not have
an exterior aerial.

that may be fitted in your vehicle; in some
cases, these are country-specific.
i You can connect a Bluetooth ®

face. This also applies if your vehicle is
