Brightness of the following lights can
be adjusted in position AUTO when
the light sensor detects night
conditions, or in position 8 or 9.
● instrument panel illumination
● Info-Display
● illuminated switches and operation elements
Turn thumb wheel A and hold until
the desired brightness is obtained.
Interior lights
During entry and exit of the vehicle,
the front and rear courtesy lights
automatically switch on and then off
after a delay.
Notice
In the event of an accident with
airbag deployment the courtesy
lights are turned on automatically.

160Driving and operatingVehicles with power button
Manual transmission: operate clutch
and brake pedal.
Automatic transmission: operate
brake pedal and move selector lever
to P or N.
Manual transmission automated:
operate brake pedal.
Do not operate accelerator pedal.
Press and release Engine Start/Stop:
an automatic procedure operates the
starter with a short delay until the
engine is running, see automatic
starter control.
Before restarting or to switch off the
engine when vehicle is stationary, press Engine Start/Stop once more
briefly.
To start the engine during an
Autostop:
● Manual transmission: during an Autostop, the engine can be
started by depressing the clutch
pedal 3 161.
● Automatic transmission or manual transmission automated:
during an Autostop, the engine
can be started by releasing the
brake pedal 3 161.
Emergency shut off during driving
If the engine needs to be switched off during driving in case of emergency,
press Engine Start/Stop for longer
than two seconds or press twice
briefly within five seconds.9 Danger
Switching off the engine during
driving may cause loss of power
support for brake and steering
systems. Assistance systems and
airbag systems are disabled.
Lighting and brake lights will
extinguish. Therefore power down the engine and ignition while
driving only when required in case of emergency.
Starting the vehicle at low
temperatures
Starting the engine without additional
heaters is possible down to -25 °С for
diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct fuel, performed services and a
sufficiently charged vehicle battery.
With temperatures below -30 °C the
automatic transmission requires a
warming phase of approx.
five minutes. The selector lever must
be in position P.
Automatic starter control
This function controls the engine
starting procedure. The driver does
not need to hold the key in position 3
or to hold Engine Start/Stop pressed.
Once applied, the system will go on
Driving and operating165button. Turn the steering wheeluntil the steering wheel lock is
felt to engage.
For vehicles with automatic
transmission, the key can only
be removed when the selector
lever is in position P.
For vehicles with manual
transmission automated, the key can only be removed from
the ignition switch when the
parking brake is applied.
● Lock the vehicle.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 230.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Notice
In the event of an accident with airbag deployment, the engine is
switched off automatically if the
vehicle comes to a standstill within a
certain time.
Emergency operation under
extreme cold temperatures
9 Warning
This emergency operation may
only be carried out in case of
extremely cold temperatures and if the vehicle is parked on a levelsurface.
In countries with extreme cold
temperatures it may be necessary to
park the vehicle without applied
parking brake.
This is an emergency operation to
avoid freezing of the parking brake.
Vehicles equipped with manual
transmission automated, electric
parking brake and power button
On vehicles with manual transmission
automated the ignition can only be
switched off if the parking brake is
applied. Therefore the following items must be carried out to release the
electric parking brake:
1. Apply electric parking brake and switch off ignition.
2. Switch on ignition by pressing and
holding Engine Start/Stop for six
seconds without operating brake
pedal.
3. Press brake pedal and release electric parking brake.
4. Switch off ignition.
Vehicles equipped with manual
transmission automated, electric
parking brake and ignition switch
On vehicles with manual transmission
automated the ignition can only be
switched off if the parking brake is
applied. Therefore the following items
must be carried out to release the
electric parking brake:

Customer information305Operating data in the vehicleControl units process data for
operation of the vehicle.
This data includes, e.g.: ● 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).
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 the 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 net-work ( 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.
