The red coolant warn-
ing lamp comes on
while the engine is run-
ning.The coolant level is too low.
If the coolant level is correct, the airflow to the engine radiator may
be blocked or the electric engine radiator fan may be malfunc-
tioning.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
XObserve the additional display messages in the multifunction
display.
XPull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.
XSecure the vehicle against rolling away (Ypage 171).
XLeave the vehicle and keep a safe distance from the vehicle until
the engine has cooled down.
XCheck the coolant level and add coolant, observing the warning
notes (
Ypage 539).
XIf you have to add coolant frequently, have the engine cooling
system checked.
XMake sure that the air supply to the engine radiator is not
blocked, e.g. by snow, slush or ice.
XDo not start the engine again until the coolant temperature is
below 248‡(120 †). Otherwise, the engine could be damaged.
XDrive to the nearest qualified specialist workshop.
XAvoid subjecting the engine to heavy loads, e.g. driving in moun-
tainous terrain, and stop-and-go traffic.

ning. A warning tone
also sounds.The coolant temperature has exceeded 248 ‡ (120 †). The air-
flow to the engine radiator may be blocked or the coolant level may

GWARNING
The engine is not being cooled sufficiently and may be damaged.
Do not drive when your engine is overheated. This can cause some
fluids which may have leaked into the engine compartment to
catch fire.
Steam from the overheated engine can also cause serious burns
which can occur just by opening the hood.
There is a risk of injury.

iPlease note the following: for the opti-
mum audio experience for all passengers
when Logic7
®is switched on, the balance
should be set to the center of the vehicle
interior.
You will achieve the best sound results by
playing video DVD media.
MP3 tracks should have a bit rate of at least
128 kbit/ s.
Surround sound playback does not func-
tion for mono signal sources, such as for
AM radio mode.
If radio reception is poor, e.g. in a tunnel,
you should switch off Logic7
®, since it may
otherwise switch dynamically between
stereo and mono and cause temporary
sound distortions.
On some stereo recordings, the sound
characteristics may differ from conven-
tional stereo playback.
iThe Logic7®Onfunction creates a sur-
round sound experience for every
passenger when playing stereo recordings, for example. It enables optimum playback
of music and films on CD or video DVD with multichannel audio formats, such as MLP,
dts or Dolby Digital. This results in sound
characteristics like those intended by the
sound engineer when the original was
recorded.
iIf you select
Logic7®Off, the sound sys-
tem plays the tracks as stored on the
medium. Due to the design of the
passenger compartment, an optimum
audio experience cannot be guaranteed for
all passengers.

You can optimize the sound in the vehicle with
the Bang & Olufsen sound system and the

Geo fencing
Geo fencing allows you to select areas which
the vehicle should not enter or leave. You will
be informed if the vehicle crosses the boun-
daries of the selected areas. You can select
the way in which you receive this information beforehand. Possible options include text
message, e-mail or an automated call.
The area can be determined as either a circle
or a polygon with a maximum of ten corners.
You can specify up to ten areas simultane-
ously. Different settings are possible for each area.
USA only: these settings can be called up
under "Owners Online" at http://
www.mbusa.com.
Alternatively, you can trigger an MB Info call
and inform the customer service representa-
tive that you wish to activate geo fencing.
