The reversing light comes on when
the ignition is on and reverse gear is
selected.
Misted light covers
The inside of the light housing may
mist up briefly in poor, wet and cold weather conditions, in heavy rain or
after washing. The mist disappears
quickly by itself; to help switch on the
headlights.Interior lighting
Instrument panelillumination control
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.

Driving and operating161Automatic transmission: operate
brake pedal and move selector lever
to P or N.
Do not operate accelerator pedal.
Press Engine Start/Stop briefly: an
automatic procedure operates the
starter with a short delay until the engine is running, see automatic
starter control.
To switch off the engine when vehicle
is stationary, press
Engine Start/Stop briefly. Automatic
transmission: apply the parking brake
and engage P.
To start the engine during an
Autostop:
● Manual transmission: during an Autostop, the engine can be
started by depressing the clutch
pedal 3 162.
● Automatic transmission: during an Autostop, the engine can be
started by releasing the brake
pedal 3 162.Emergency engine shut off during
driving
If the engine needs to be switched offduring driving in case of emergency,
press Engine Start/Stop for longer
than 2 seconds or press twice briefly
within 5 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. 5 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
starting automatically until the engine
is running. Because of the checking
procedure, the engine starts running after a short delay.

166Driving and operatingFor vehicles with automatic
transmission, the key can only
be removed when the selector
lever is in position P.
● Lock the vehicle by pressing the
button on the door handle or the
button e on the remote control.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 228.
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 temperatures9 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.
Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Exhaust filter
The exhaust filter is a particle filter for diesel and petrol engines.

300Customer informationOperating 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 allowinformation 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. triggeringof 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.
