?NThe red coolant warning lamp comes on while the engine is running.
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 malfunctioning.
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 177).
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 333).
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 heavy loads on the engine as you do so, e.g. driving in mountainous terrain
and stop-start traffic.
?N The red coolant warning lamp comes on while the engine is running. A warning
tone also sounds.
The coolant temperature has exceeded 248 ‡(120 †). The airflow to the engine
radiator may be blocked or the coolant level may be too low.
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.

General notes
The multimedia system section in this manual
describes the basic principles for operation.
More information can be found in the Digital
Operator's Manual.
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for the
country in which you are currently driving when
operating the multimedia system.
The multimedia system calculates the route to
the destination without taking the following into
account, for example:
Rtraffic lights
Rstop and yield signs
Rparking or stopping restrictions
Rroad narrowing
Rother road and traffic rules and regulations
The multimedia system may give incorrect nav-
igation recommendations if the actual street/
traffic situation does not correspond with the
digital map's data.
For example:
Ra diverted route
Rthe road layout or the direction of a one-way
street has been changed
For this reason, you must always observe road
and traffic rules and regulations during your
journey. Road and traffic rules and regulations
always have priority over multimedia system
driving recommendations.
Navigation announcements are intended to
direct you while driving without diverting your
attention from the road and driving. Please always use this feature instead of con-
sulting the map display for directions. Looking
at the icons or map display can distract you from
traffic conditions and driving, and increase the
risk of an accident.
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled equip-
ment and meets the FCC radio frequency (RF)
Exposure Guidelines in Supplement C to OET65.
This equipment has very low levels of RF energy
that is deemed to comply without maximum
permissive exposure evaluation (MPE). But it is
desirabl
e tha
t it should be installed and oper-
ated with at least 8inches (20 cm) and more
between the radiator and a person's body
(excluding extremities: hands, wrists, feet and
legs.)
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
Function restrictions
For safety reasons, some functions are restric-
ted or unavailable while the vehicle is in motion.
You will notice this, for example, because either
you will not be able to select certain menu items
or a message will appear to this effect.

Overview
General notes
!Do not use the space in front of the display
for storage. Objects placed here could dam-
age the display or impair its function. Avoid
any direct contact with the display surface.

very sensitive high-gloss surface; there is a
risk of scratching. If you have to clean the
screen, however, use a mild cleaning agent
and a soft, lint-free cloth.
The display must be switched off and have
cooled down before you start cleaning. Do not
apply pressure to the display surface when
cleaning it, as this could cause irreversible dam-
age to the display.
