Turn lights
O flashes green.
Flashes if a turn light or the hazard
warning flashers are activated.
Rapid flashing: failure of a turn light or associated fuse.
An audible warning can be heard
when the turn lights are on.
Bulb replacement 3 177.
Fuses 3 183.

98Instruments and controlsTurn lights 3 113.
Seat belt reminder
X illuminates or flashes red.
If the seat belt is unfastened, control
indicator X will flash when vehicle
speed exceeds approx. 16 km/h. A warning chime also sounds for up to
two minutes.
If the seat belt is fastened, the
indicator light extinguishes.
Note
Heavy objects on the front seats
may cause control indicator X to
illuminate. Remove the object from
the seat or fasten the seat belt.9 Warning
Fasten seat belt before each trip.
In the event of an accident, people
not wearing seat belts endanger their fellow occupants and
themselves.
Three-point seat belts 3 56.
Airbag and belt tensioners
v illuminates yellow.
Illuminates briefly when the ignition is switched on.
If it does not illuminate or illuminates
whilst driving, there is a fault in the
belt tensioner or the airbag system.
The airbags and belt tensioners may
fail to trigger in the event of an
accident.
Deployment of the belt tensioners or airbags is indicated by continuous
illumination of v.9 Warning
Have the cause of the fault
remedied immediately by a
workshop.
Belt tensioners 3 55.
Airbag system 3 60.
Airbag deactivation Ó ON illuminates yellow.
The front passenger airbag is
activated.
* OFF illuminates yellow.
The front passenger airbag is
deactivated 3 64.
If both control indicators ÓON and
* OFF are illuminated
simultaneously, there is a system
failure. The status of the system is not discernible, therefore no person is
permitted to occupy the front
passenger seat. Contact a workshop
immediately.
If illuminated in conjunction with v or
j , seek the assistance of a
workshop.9 Danger
Risk of fatal injury for a child using
a child restraint system together
with activated front passenger
airbag.
Risk of fatal injury for an adult
person with deactivated front
passenger airbag.
Airbag system 3 60.
Belt tensioners 3 55.

104Instruments and controlsInfo Display
The Info Display displays
Infotainment system information, the
time and depending on version the
outside temperature.
Press X to switch the Infotainment
system on. Alternatively, it
automatically switches on when the
ignition is switched on.
Depending on system, the
Infotainment system is operated via
buttons and rotary knobs on the
Infotainment system fascia, the
steering column controls, the voice
recognition system (if available) or via
the touchscreen display.
Touchscreen operation
Make the appropriate selection from
the available menus and options by
touching the display screen with the
finger.
For further information, refer to the
Infotainment manual.Vehicle messages
Messages are displayed in the Driver Information Centre and may be
accompanied by illumination of
control indicator j or C in the
instrument cluster.
Information messages Information messages regarding, e.g.
engine starting conditions, stop-start
system, parking brake application,
central locking, steering wheel lock
etc. provide the current status of
certain vehicle functions and
instructions for use.
Fault messages Fault messages regarding, e.g. fuel
filter, airbags, exhaust emissions etc.
are displayed together with control
indicator j. Drive with caution and
seek the assistance of a workshop as
soon as possible.
To remove fault messages, e.g.
" CHECK INJECTION ", from the
display, press button on end of wiper
lever. After a few seconds the
message may disappear

222Customer informationOperating data in the vehicleControl units process data for
operation of the vehicle.
This data includes, e.g.: ● vehicle status information (e.g. speed, movement delay, lateral
acceleration, wheel rotation rate, "seat belts fastened" display)
● ambient conditions (e.g. temperature, rain sensor,
distance sensor)
As a rule such data is transient, not
stored for longer than an operational
cycle, and only processed on board the vehicle itself. Control units often
include data storage (including the
vehicle key). This is used to allow
information to be documented
temporarily or permanently on vehicle
condition, component stress,
maintenance requirements and
technical events and errors.Depending on technical equipment
level, the data stored is as follows:
● system component operating states (e.g. fill level, tyre
pressure, battery status)
● faults and defects in important system components (e.g. lights,
brakes)
● system reactions in special driving situations (e.g. triggering
of an airbag, actuation of the
stability control systems)
● information on events damaging the vehicle
● for electric vehicles the amount of
charge in the high-voltage
battery, estimated range
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used when necessary. Staff working
for the service network ( e.g. garages,
manufacturers) or third parties (e.g.breakdown services) can read the
data from the vehicle. The same
applies to warranty work and quality
assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data which is read out,
documents the technical condition of
the vehicle or individual components
and assists with fault diagnosis,
compliance with warranty obligations
and quality improvement. This data,
in particular information on
component stress, technical events,
operator errors and other faults, is
transmitted to the manufacturer
where appropriate, together with the
vehicle identification number. The
manufacturer is also subject to
product liability. The manufacturer
potentially also uses operating data
from vehicles for product recalls. This
data can also be used to check
customer warranty and guarantee
claims.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs or at
your request.
