Control of the vehicle
Never coast with engine not
running (except during Autostop)
Many systems will not function in this
situation (e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there may be a controlled
reduction in power steering assist and
vehicle speed is reduced.
Stop-start system 3 117.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Use only floor mats which fit properly
and are fixed by the retainers on the
driver's side.
Driving downhill
Engage a gear when driving downhill to ensure that sufficient brake
pressure is available.
Driving and operating115SteeringIf power steering assist is lost
because the engine stops or due to a
system malfunction, the vehicle can
be steered but may require increased
effort.Caution
Never leave the steering wheel on
full lock when the vehicle is
stationary, as this may damage
the power steering pump.
Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and engine oil consumption may be
higher.
Additionally, the cleaning process of
the diesel particle filter may take
place more often.

Autostop may be inhibited to allow for
charging of the vehicle battery.

116Driving and operatingSteering wheel lock
Remove key from ignition switch and
turn steering wheel until it engages.
Starting the engine
Turn key to position 1 and move the
steering wheel slightly to release the
steering wheel lock.
Manual transmission: operate clutch
and brake pedal.
Manual transmission automated:
operate brake pedal, the transmission
automatically shifts to N (neutral).
Do not operate the accelerator pedal.
Diesel engine: turn key to position 1
for preheating until control
indicator ! extinguishes.
Turn key briefly to position 2 and
release.
Before restarting or to switch off the
engine, turn key back to position 0.
Autostop During an Autostop, the engine is
restarted automatically by depressing
the clutch pedal.
Vehicles with manual transmission
automated (MTA): Shift to a forward
gear, release brake pedal or move
lever to +, – or R to enable an
automatic restart.
Stop-start system 3 117.Starting the vehicle at low
temperatures
The start of 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.
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.
Vehicle shutdown
Fuel cut-off system In the event of a collision of a certain
severity, the fuel system is cut-off and
the engine is switched off
automatically, for safety reasons.
Driving and operating117Control indicator 9 illuminates if the
fuel cut-off switch is triggered and,
depending on version, a
corresponding warning message may
also appear in the Driver Information
Centre 3 91.
Generic warning control indicator 9
3 82.
Note
In addition, the vehicle is
automatically unlocked and the
hazard warning flashers and interior lights are illuminated.
Turn the ignition key to position 0 to
prevent vehicle battery discharge and
seek the assistance of a workshop
immediately. Have the vehicle
checked for fuel leaks in the engine
compartment, beneath the vehicle
and near the fuel tank.
To reset the fuel cut-off system and
enable the vehicle to be driven:
1. Turn the ignition key to position 1
3 115.
2. Fully actuate the right turn signal light 3 102.
3. Deactivate the right turn signal light.4. Fully actuate the left turn signallight.
5. Deactivate the left turn signal light.
6. Repeat steps 2, 3, 4 and 5.
7. Turn the ignition key to position 0.9 Danger
If you can smell fuel in the vehicle,
or a fuel leak is present, have the
cause of this remedied
immediately by a workshop. Do
not reset the fuel cut-off system, to avoid the risk of fire.
Fuel system messages 3 97.
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 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 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. It
starts the engine automatically as
soon as the clutch is depressed.
A vehicle battery sensor ensures that an Autostop is only performed if thevehicle battery is sufficiently charged
for a restart.
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.
Driving and operating121Engine exhaust9Danger
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
The diesel particle filter system filters
harmful 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 15 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.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If the cleaning of the filter is required
and if previous driving conditions did
not enable automatic cleaning, it will
be indicated by control indicator %.
Depending on version, a warning
message may also appear in the
Driver Information Centre 3 91.
Control indicator % illuminates when
diesel particle filter is full. Start
cleaning process as soon as possible to avoid damage to the engine.
Cleaning process
To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm. Shift down if
necessary. Diesel particle filter
cleaning is then started.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
Control indicator % extinguishes as
soon as the self-cleaning operation is
complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
