Cigarette lighter in the front com-
partment
X
To use the cigarette lighter: turn the key
to position 1 in the ignition lock
(Y page
127).
X Press in cigarette lighter :.
The cigarette lighter will pop out automati-
cally when the heating element is red-hot.
X Pull the cigarette lighter out of the socket by
its handle.
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

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.
You will find information on retrofitting electri-
cal or electronic equipment under “Vehicle
electronics” (Y page

304). Mobile communications equipment
