General notes
Some systems carry out a self-diagnosis when the ignition is switched on. Several warning and
indicator lamps can thereby temporarily light up or flash. This behaviour is non-critical. These
warning and indicator lamps only indicate a malfunction if they light up or flash after the engine is started or during a journey. 246

General notes
The multimedia system section in this manual
describes the basic principles for operation.
More information can be found in the Digital
Owner's Manual. Important safety notes
G
WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the country in which you are currently driving whenoperating the multimedia system.
The multimedia system calculates the route to
the destination without taking the following into
account, for example:
R traffic lights
R stop and give way signs
R parking or stopping restrictions
R road narrowing
R other 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:
R a diverted route
R the 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. 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 polarised 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. If necessary, 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.

pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt cannot protect as intended and
could result in additional injury.
R Objects or loads in the boot cannot be
restrained by the seat backrest.
This poses an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged before every trip.
Observe the loading guidelines (Y page 265).
The left-hand and right-hand rear seat backrests can be folded down separately to increase the
boot capacity.

fold one or both parts of the rear seat back-
rest forwards, the respective front seat
moves forward slightly, when necessary, in
order to avoid contact. X

sary, move the driver's or front-passenger
seat forwards.
