92Instruments and controlsThe fuel economy gauge is enabled
by default.
Depending on version, the fuel
economy gauge (or 'driving style
indicator') can be disabled via the
Infotainment system. Refer to
Infotainment manual for further
information.
Service display When the ignition is switched on, theremaining distance before the next
service is due may be shown briefly in
the Driver Information Centre. Based
on driving conditions, the interval at
which a service will be indicated can
vary considerably.
The 'distance before service' display
can also be shown by pressing button on end of wiper lever for approx.
5 seconds.
When the remaining distance before
the next service is less than
1000 miles or one month , a message
appears in the Driver Information
Centre.When the distance reaches 0 miles or
the service date is due, control
indicator j illuminates in the
instrument cluster and the Driver
Information Centre respectively, and
a corresponding message appears in the Driver Information Centre.
The vehicle needs a service. Seek the
assistance of a workshop.
Resetting the service displayAfter a service, the service display
must be reset:
Select the 'distance before service'
display in the Driver Information
Centre by pressing button repeatedly
on the end of the wiper lever, then
press and hold button for approx.
10 seconds until the 'distance before
service' is displayed continuously, i.e. the display no longer flashes.
On some vehicles, it may be
necessary to press and hold the
button twice. In this event, proceed as
follows:
After selecting the 'distance before
service' display, press and hold
button for approx. 10 seconds until
the 'distance before service' flashes inthe display. Then press and hold
button again for approx. 10 seconds
to reset the service interval.
If control indicator j does not
extinguish from the instrument
cluster, drive a minimum of 10 miles
then switch off ignition for at least
1 minute before repeating procedure.

Control indicators The control indicators described are
not present in all vehicles. The
description applies to all instrument
versions.
Depending on the equipment the
position of the control indicators may
vary.
When the ignition is switched on,
most control indicators will illuminate
briefly as a functionality test.

104Instruments and controlsEngine oil levelIf the minimum engine oil level is
reached, a message is displayed in
the Driver Information Centre 3 101
for 30 seconds after the engine is
started.
Check oil level 3 166.Trip computer
The trip computer provides
information on driving data, which is
continually recorded and evaluated
electronically.
Depending on vehicle, the following
functions can be selected by pressing button repeatedly on end of wiper
lever:
● fuel used
● average consumption
● instantaneous consumption
● range
● distance travelled
● average speed
● AdBlue percentage remaining 3 140
● distance before service 3 92
● clock 3 86
● outside temperature 3 85
● cruise control and speed limiter stored speed 3 151
● fuel economy rating (ecoScoring)
● fault and information messages
● odometer 3 90
● trip odometer 3 90
Fuel used Displays the amount of fuel
consumed since the last reset.
The measurement can be restarted at
any time by pressing and holding the
button.
Average consumption The value is displayed after driving a
distance of 0.25 miles.
226Customer informationThis data includes, for example:● Vehicle status information (e.g. wheel rotation rate, speed,
movement delay, lateral
acceleration, "seatbelts
fastened" display),
● Ambient conditions (e.g. temperature, rain sensor,
distance sensor).
Most of this data is volatile and is
processed only in the vehicle itself, and not beyond the operating time.
Moreover, many control units include
data storage device (amongst others 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.
The following information, for
example, is stored:
● System component operating states (e.g. fill level, tyre
pressure, battery status),
● State of charge of the high voltage battery, estimated range
(in the case of electric vehicles),● Faults and defects in important system components (e.g. lights,
brakes),
● System reactions in special driving situations (e.g. triggeringof an airbag, actuation of the
stability control systems),
● Information on events damaging the vehicle.
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, the operating
data saved can be read together with the vehicle identification number andused if necessary. Staff working for
the service net-work (e.g. garages, manufacturers) or third parties (e.g.
breakdown services) can read the
data from the vehicle. Services
include repair services, maintenance
processes, warranty cases 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 has been read
out documents the technical conditionof 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 needs operating data
from vehicles for product recalls.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs.
Comfort and infotainment
functions
Comfort settings and custom settings
can be stored in the vehicle and
changed at any time.
