94Instruments and controlsCaution
If engine coolant temperature is
too high, stop vehicle, switch off
engine. Danger to engine. Check
coolant level.
For physical reasons, the coolant temperature gauge shows the coolant temperature only if the coolant level is adequate.
Engine oil level monitor
The engine oil level monitor is correct
only if the vehicle is parked on a level
surface with a cold engine.
If the engine oil level is correct when
the ignition is switched on OIL LEVEL
CORRECT appears briefly in the
Driver Information Centre.
If the engine oil is above the minimum level, press the trip computer button
on the end of the wiper lever within
30 seconds of switching on the
ignition. The message OIL LEVEL is
displayed in combination with the
squares that correspond to the oil
level.
As the oil level diminishes, the
squares in the display are replaced
with dashes.▢▢▢▢▢▢:maximum level▢▢▢- - -:intermediate level- - - - - -:minimum level
If the minimum engine oil level is
reached TOP-UP OIL LEVEL is
displayed in combination with control
indicator j after the ignition is
switched on for 30 seconds. Check
and top up engine oil 3 181.
To exit the oil level monitor display,
press either trip computer button.

Service display When the ignition is switched on, the
remaining 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.
When the remaining distance before
the next service is less than
1800 miles or two months, SERVICE
IN appears in the Driver Information
Centre.
When the distance reaches 0 miles or
the service date is due, control
indicators o and j illuminate in the
instrument cluster and SERVICE
DUE appears in the Driver
Information Centre.
The vehicle needs a service. Seek the assistance of a workshop.
Resetting the service display After a service, the service display
must be reset: if available, select the
distance before service display in the
Driver Information Centre, then press and hold button on end of wiper lever
for approx. ten seconds until the
distance before service is displayed
continuously.

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
● distance before service 3 94
● clock 3 89
● cruise control 3 161
● speed limiter 3 163
● fault and information messages
● odometer 3 92
● trip odometer 3 92
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 on the end of the wiper lever.
Average consumption The value is displayed after driving a
distance of 0.25 miles.
Average consumption is displayed,
taking into consideration the distance
travelled and the fuel used since the
last reset.
The measurement can be restarted at
any time.
236Customer 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.
Customer information237Comfort and infotainment
functions
Comfort settings and custom settings
can be stored in the vehicle and
changed or reset at any time.
Depending on the equipment level in
question, these include
● seat and steering wheel position settings
● chassis and air conditioning settings
● custom settings such as interior lighting
You can input your own data in the
infotainment functions for your
vehicle as part of the selected
features.
Depending on the equipment level in
question, these include
● multimedia data such as music, videos or photos for playback in
an integrated multimedia system
● address book data for use with an
integrated hands-free system or an integrated navigation system● input destinations
● data on the use of online services
This data for comfort and
infotainment functions can be stored
locally in the vehicle or be kept on a
device that you have connected to the
vehicle ( e.g. a smartphone, USB stick
or MP3 player). Data that you have input yourself can be deleted at any
time.
This data can only be transmitted out
of the vehicle at your request,
particularly when using online
services in accordance with the
settings selected by you.
Smartphone integration, e.g.
Android Auto or Apple CarPlay
If your vehicle is equipped
accordingly, you can connect your
smartphone or another mobile device
to the vehicle so that you can control
it via the controls integrated in the
vehicle. The smartphone image and
sound can be output via the
multimedia system in this case. At the same time, specific information is
transmitted to your smartphone.
Depending on the type of integration,this includes data such as position
data, day / night mode and other
general vehicle information. For more
information, please see the operating
instructions for the vehicle /
infotainment system.
Integration allows selected
smartphone apps to be used, such as navigation or music playback. No
further integration is possible
between smartphone and vehicle, in
particular active access to vehicle
data. The nature of further data
processing is determined by the
provider of the app used. Whether
you can define settings, and if so
which ones, is dependent on the app
in question and your smartphone's
operating system.
