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.
Additional 12 V sockets may be located in the
rear corner trim next to the tailgate and in the
side trim on the left and right-hand sides.
X Lift up the cover of socket :. Mobile communications equipment
G
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.
Failure to observe the Mercedes-Benz installa-
tion specifications can result in the invalida-
tion of your vehicle's operating permit.

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

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).
