Emergency call
Emergency call function Vehicles featuring the emergency call
function are equipped with a red
SOS button in the overhead console.
The emergency call function will
establish a connection to the nearest
public safety answering point (PSAP).
A minimum set of data including
vehicle and location information will
be sent to the PSAP.
Note
Establishing an emergency call may not be possible in areas without
sufficient network availability or due
to hardware damage during an
accident.
Automatic crash notification
In case of an accident with airbag
deployment, an automatic
emergency call is established and an
automatic crash notification will be
transmitted to the next public safety answering point.
Emergency assistance
In case of an emergency you can also
manually place an emergency call by pressing the red SOS button for more
than two seconds. The LED flashes to confirm that a connection to the
nearest PSAP is being established.
The LED illuminates steadily as long
as the call is active.
Pressing the SOS button immediately
a second time will terminate the call.
The LED switches off.

Press A/C to switch on cooling.
Activation is indicated by the LED in

when the engine is running and
climate control fan is switched on.
150Climate controlMaintenanceAir intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when the
outside temperature is too low.
Service For optimal cooling performance, it is recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check
Driving and operating157Starting the vehicle at lowtemperatures
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.Possible reasons for a non-starting
engine:
● clutch pedal not operated (manual transmission)
● brake pedal not operated or selector lever not in P or N
(automatic transmission)
● timeout occurred
Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time,
especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.
Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but accelerator pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.Stop-start system
The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. The ignition stays on.
The engine switches on automatically
when certain conditions apply or
restart is activated by a driver.
Activation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.
162Driving and operatingAutomatic cleaning process
The exhaust filter system filters soot
particles out of the exhaust gases.
The system includes a self-cleaning
function that runs automatically
during driving without any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
conditions and may take up to
25 minutes. Typically it needs
between 7 and 12 minutes. Autostop
is not available and fuel consumption may be higher during this period. The
emission of smells and smoke during
this process is normal.
System requires cleaning
Under certain conditions, e.g. driving
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and if previous driving conditions did not
enable automatic cleaning, it will be
indicated by a warning message in
the Driver Information Centre.A warning message appears when
exhaust filter is full. Start cleaning
process as soon as possible.
A warning message also appears
when exhaust filter has reached the
maximum filling level. Start cleaning
process immediately to avoid
damage to the engine.
Activate self-cleaning process
Cleaning process is completed more
quickly at high engine speeds and
loads. Therefore, drive in lower gears
than normal, and use manual gear
selection on vehicles with automatic
transmission. Usage of electrical consumers like air conditioning and
heated windows to increase engine
load supports cleaning process.Caution
If possible, do not interrupt
cleaning process. Drive until
cleaning is completed to avoid the
need for service or repair by a
workshop.
Vehicles with petrol engine
To activate cleaning process,
continue driving, keep engine speed
above 2500 rpm. Shift down if
necessary.
Drive dynamically at different engine
speeds. Use engine brake for
deceleration, if possible.
Keep on driving until self-cleaning
operation is complete and the display
message disappears.Vehicles with diesel engine
To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm, ideally and
continuously around 2500 rpm. Shift
down if necessary.
Keep on driving until self-cleaning
operation is complete and the display message disappears.
