The cigarette lighter socket can be used for
accessories with a maximum power consump-
tion of 180 W

(15 A).
If you use the sockets to connect accessories
for long periods when the engine is switched
off, the starter battery may discharge. An
emergency cut-off ensures that the on-board
voltage does not drop too low. If the on-board
voltage is too low, power to the socket is auto-
matically cut. This ensures that there is suffi-
cient power to start the engine. 12 V socket
When the key is turned to position 1 in the
ignition lock, the sockets can be used for accessories with a maximum power consump-
tion of

180 W (15 A).
If you use the sockets for long periods when
the engine is switched off, the starter battery
may discharge. If the on-board voltage is too
low, it might then no longer be possible to
start the engine.
The socket in the center console and the
socket in the side of the cargo compartment
are not automatically deactivated if the on-
board voltage is low. The additional sockets in
the rear compartment are automatically deac-
tivated if the on-board voltage is low.

WARNING
If you operate information and communica-
tion devices while driving, you may be dis-
tracted from the traffic conditions. You
could even lose control of the vehicle. There
is a risk of an accident.
Only operate these devices when the vehicle
is stationary.
Observe the legal requirements for the country
in which you are currently driving when operat-
ing mobile communication equipment.
Please remember, a navigation system does
not supply information on the load-bearing
capacity of bridges or the overhead clearance
of underpasses. The driver remains responsi-
ble for safety at all times.
You and others can suffer health-related dam-
age through electromagnetic radiation. By
using an exterior antenna, a possible health
risk caused by electromagnetic fields, as dis-
cussed in scientific circles, is taken into
account. Only have the exterior antenna instal-
led by a qualified specialist workshop.

G
WARNING
When objects are unsecured or inadequately
secured, they can slip, turn over or be
thrown about, striking vehicle occupants.
This also applies to:
R luggage or loads
R seats which have been removed and are
being transported in the vehicle in an
exceptional case.
There is a risk of injury, particularly in the
event of a braking maneuver or abrupt
change in direction.
Always stow objects in such a way that they
cannot be tossed about. Before traveling,
secure objects, luggage or loads to prevent
them slipping or tipping over. If you remove
a seat, store it preferably outside the vehi-
cle. G
WARNING
As a result of improperly placed or unevenly
distributed loads, the center of gravity of the
load being transported may be too high or
too far back. This can significantly impair
handling as well as steering and braking
characteristics. There is a risk of an acci-
dent. Always make sure that the center of gravity
of the load is:
R between the axles
and
R as low as possible, near the rear axle. G
WARNING
When the permissible wheel loads, axle
loads and/or the maximum permissible
gross vehicle weight are exceeded, driving
safety is compromised. The handling as well
as steering and braking characteristics may
be significantly impaired. Overloaded tires
may overheat, causing them to burst. There
is a risk of an accident.
When transporting a load, always observe
the permissible wheel loads, axle loads and
the maximum permissible gross vehicle
weight for the vehicle (including occupants).
! If you are using a roof carrier, observe the
maximum roof load and maximum roof car-
rier load.
R Do not stack luggage or loads higher than
the backrests.
R Objects to be transported should preferably
be stowed in the cargo compartment.
R When transporting luggage, always use the
cargo tie-down rings for securing loads and
a cargo net, if installed.
R Use cargo tie-down rings and fasteners
which are suitable for the weight and size of
the load.
When using suitable load securing aids and tie
downs, always follow the manufacturer's oper-
ating instructions, in particular the notes on
discard criteria contained therein.
Load securing aids or tie downs must not be
used if:
R identification marks are missing or illegible
R there are yarn breakages, damage to bear-
ing seams or other signs of tearing
R there are signs of shearing, deformation,
pinching or other damage
R there is damage to clamping or connecting
elements
Load securing aids and tie downs in this condi-
tion are ready for discard and must be 242
Loading guidelines
Transporting loads

X
Always transport loads in the cargo com-
partment and with the seat backrests folded
up and properly locked in position.
X Always place the load against the backrests
of the front or rear seats.
X Move large and heavy loads as far towards
the front of the vehicle as possible against
the front or rear seats. Stow the load flush
with the rear or front seats.
X Always additionally secure the load with
suitable load-securing aids or tie downs.
Observe the following notes:
R Do not stack loads higher than the upper
edge of the backrests.
R Transport loads behind seats that are not
occupied.
R If the rear bench seat is not occupied, insert
the seat belts crosswise into the buckle of
the opposite seat belt. Cargo compartment variations
You can vary the cargo compartment accord-
ing to your transportation requirements as fol-
lows:
R by folding the seat backrests forward to the
table position.
R by removing the rear bench seat.
You will find information about rear bench
seats in the "Rear bench seats" section
( Y page
89). Securing loads
Important safety notes
G
WARNING
If you attach the tie-down incorrectly when
securing the load, the following may occur in
the event of abrupt changes in direction,
braking maneuvers or an accident:
R the cargo tie-down rings may become
detached or the tie-down may tear if the
permissible load is exceeded
R the load may not be restrained. This may cause the load to slip, tip over or
be tossed about, striking vehicle occupants.
There is a risk of an accident and injury.
Always tension the tie-downs in the proper
manner and only between the described
cargo tie-down rings. Always use tie-downs
designed specifically for the loads.
! Observe the information on the maximum
loading capacity of the individual cargo tie-
down points.
If you use several cargo tie-down points to
secure a load, you must always take the
maximum loading capacity of the weakest
cargo tie-down point into account.
If you brake hard, for example, the forces
acting could be up to several times the
weight force of the load. Always use multi-
ple cargo tie-down points in order to distrib-
ute the force absorption. Load the ancho-
rages evenly.
As the driver, you are responsible for ensuring
that: R The load is secured against slipping, tipping,
rolling or falling off in normal traffic condi-
tions, should the vehicle swerve to avoid an
obstacle, in the event of maximum full-stop
braking and on poor road surfaces
R The applicable requirements and guidelines
relating to load-securing practices are met
If this is not the case, this may constitute a
punishable offense, depending on local leg-
islation and any ensuing consequences.
Always observe the legal requirements for
the country you are currently in.
Make sure that the load is secure before every
journey and at regular intervals during a long
journey. Correct an incorrectly or inadequately
secured load if necessary.
Always observe the operating instructions or
the notes of the lashing strap manufacturer for
the operation of the lashing strap.
You can obtain information about securing the
load correctly from the manufacturer of the
load securing aids or tie down for securing the
load. Also observe the safety information in
the loading directions ( Y page 242).

G
WARNING
The load protection net alone cannot
restrain or secure heavy objects, luggage or
heavy loads. In the event of abrupt changes
in direction, braking maneuvers or an acci-
dent, you may be struck by unsecured loads.
There is a risk of injury, possibly even fatal.
Always stow objects in such a way that they
cannot be tossed about. Secure objects, lug-
gage and loads to prevent them slipping or
tipping over, e.g. by lashing them down,
even when using the load protection net. G
WARNING
If vehicle occupants are seated behind a
load protection net, they may be squeezed
up against the load protection net. There is
a risk of injury, particularly in the event of
braking maneuvers or abrupt changes in
direction.
Never allow vehicle occupants to sit behind
the load protection net.
The load protection net borders the cargo
compartment. It protects vehicle occupants
from light objects and/or luggage slipping or
tipping over. Always observe the notes on
securing loads
(Y page 244).
You can install the load protection net at an
angle behind the front seats or behind the first

WARNING
When you load the roof, the center of gravity
of the vehicle rises and the usual driving
characteristics, as well as steering and brak-
ing, change. The vehicle tilts more severely
when cornering and may react more slug-
gishly to steering input.
If you exceed the maximum roof load, the
driving characteristics, as well as the steer- ing and braking, will be greatly impaired.
There is a risk of an accident.
Adjust your driving style and never exceed
the maximum roof load.
You will find information about the maximum
roof load under "Cargo tie-down points and
carrier systems"
(Y page 313).
! Make sure that:
R the screws of the roof carrier are tight-
ened to a maximum torque of 7.4 lb-ft
(10 Nm) in the threaded holes provided
and
R there is a minimum bolt penetration of
4 turns.
Only install roof carriers and rear racks that
have been approved or recommended for
Mercedes-Benz vehicles. This will help avoid
damage to the vehicle.
You can install a roof carrier on the roof and,
for example, a rear-mounted cycle rack on the
tailgate.
Install the protective caps on the securing
threads after you have removed the roof car-
rier.
If you have installed a rear rack on the tailgate,
the additional weight reduces the assistance
provided by the gas pressure springs when the
tailgate is opened. You will then need more
force to open the tailgate. At low outside tem-
peratures below freezing you will need to pro-
vide extra support for the tailgate to prevent it
from sinking unintentionally. Carrier systems
