GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
!If the coolant temperature is too high, a dis-
play message is shown.
If the coolant temperature display is in the
area marked in red, do not continue driving.
Otherwise, the engine will be damaged.
The coolant temperature gauge is in the instru-
ment cluster on the right-hand side (
Ypage 37).
Under normal operating conditions and with the
specified coolant level, the coolant temperature gauge may rise to the red marking.

General notes
The multimedia system section in this Opera-
tor's Manual describes the basic principles for
operation. More information can be found in theDigital Operator's Manual.
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle when driving, you may be distracted from
the traffic situation. You could also lose con-
trol of the vehicle. There is a risk of an acci-
dent.
Only operate this 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). How-
ever, it is
recommended to insta

ll it at a distance
of at least 8 inches (approx. 20 cm) between the
radiation source and a person's body (not
including limbs such as 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.
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.

Operating system
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.
Pressure on the display surface may result in
impairments to the display, which could be
irreversible.
Wearing polarized sunglasses may impair your
ability to read the display.
The display has an automatic temperature-con-
trolled switch-off feature. The brightness is
automatically reduced if the temperature is too
high. The display may temporarily switch off
completely.
Cleaning instructions
!Do not touch the display. The display has a
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.
