56Seats, restraints
The front passenger airbag system
can be deactivated via a key-
operated switch on the passenger side of the instrument panel.
Use the ignition key to choose the position:
* OFF:front passenger airbag is
deactivated and will not
inflate in the event of a
collision. Control indicator
* OFF illuminates
continuously in the centre
consoleÓ ON:front passenger airbag is
active9 Danger
Deactivate passenger airbag only
in combination with the use of a
child restraint system, subject to
the instructions and restrictions in
the table 3 60.
Otherwise, there is a risk of fatal
injury for a person occupying a
seat with a deactivated front
passenger airbag.
If the control indicator ÓON
illuminates for approx. 60 seconds
after the ignition is switched on, the
front passenger airbag system will
inflate in the event of a collision.
If the control indicator *OFF
illuminates after the ignition is
switched on, the front passenger
airbag system is deactivated. It stays
on while the airbag is deactivated.
If both control indicators are
illuminated at the same time, there is
a system failure. The status of the
system is not discernible, therefore
no person is allowed to occupy the
front passenger seat. Contact a
workshop immediately.
Consult a workshop immediately if
neither of the two control indicators
are illuminated.
Change status only when the vehicle is stopped with the ignition off.
Status remains until the next change.

General services
If you need any information e.g.
opening hours, points of interest and
destinations or if you need any
support e.g. in the case of a vehiclebreakdown, a flat tyre and empty fuel
tank, press Z to establish a
connection to an advisor.
Emergency services
In the case of an emergency situation,
press [ and talk to an advisor. The
advisor then contacts emergency or
assistance service providers and
directs them to your vehicle.
In the case of an accident with
activation of airbags or belt
tensioners, an automatic emergency
call is established. The advisor is
immediately connected to your
vehicle to see whether help is
needed.
Notice
Establishing an emergency call may
not be possible in areas without
sufficient network availability or due
to hardware damage during an
accident.
Wi-Fi hotspot
The Wi-Fi hotspot of the vehicle
provides internet connectivity with a
maximum speed of 4G/LTE.
112LightingInterior 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 operating131Automatic transmission: operate
brake pedal and move selector lever
to P or N.
Do not operate accelerator pedal.
Press and release Start/Stop: an
automatic procedure operates the
starter with a short delay until the engine is running.
Before restarting or to switch off the
engine when vehicle is stationary, press Start/Stop once more briefly.
Manual transmission: during an
Autostop, the engine can be started
by depressing the clutch pedal
3 131.
Automatic transmission: during an
Autostop, the engine can be started
by releasing the brake pedal 3 131.
Emergency shut off during driving If the engine needs to be switched offduring driving in case of emergency,
press Start/Stop for five seconds.9Danger
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.
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.
Driving and operating135load 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.
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.
Diesel particle filter
Automatic cleaning process
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases.
The start of saturation of the particle
filter is indicated by the temporary illumination of % or H ,
accompanied by a message in the
Driver Information Centre.
As soon as the traffic conditions
permit, regenerate the filter by driving at a vehicle speed of at least 40 mph
until the control indicator
extinguishes.
Notice
On a new vehicle, the first particle
filter regeneration operations may
be accompanied by a burning smell,
which is normal. Following
prolonged operation of the vehicle at very low speed or at idle, you may,
in exceptional circumstances, notice
the emission of water vapour at the
exhaust on acceleration. This does
not affect the behaviour of the
vehicle or the environment.
Cleaning process not possible
If % or H stays on, accompanied
by an audible signal and a message,
this indicates that the particle filter
additive level is too low.
The reservoir must be topped-up
without delay. Seek the assistance of
a workshop.
