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 will be a controlled reduction in power steering assist and vehicle
speed is reduced.
Stop-start system 3 110.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Steering
If 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.
108Driving and operatingCaution
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 and the cleaning process of the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging the
battery.

automated (MTA): Shift to a forward
gear, release brake pedal or move
lever to +, – or R to enable an
automatic restart.
Stop-start system 3 110.
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 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.
Control 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 (DIC) 3 85.
Generic warning control indicator 9
3 76.
Notice
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 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.
110Driving and operatingTo reset the fuel cut-off system and
enable the vehicle to be driven:
1. Turn the ignition key to position 1 3 108.
2. Fully actuate the right turn signal light 3 96.
3. Deactivate the right turn signal light.
4. Fully actuate the left turn signal light.
5. Deactivate the left turn signal light.
6. Repeat steps 2, 3, 4 and 5.
7. Turn the ignition key to position 0.9Danger
If you can smell fuel in the vehicle,
or a fuel leak is present, have thecause 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 91.
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.
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 battery sensor ensures that an
Autostop is only performed if the
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.Deactivation
Deactivate the stop-start system
manually by pressing ^ in the centre
console. LED in the button illuminates
to confirm deactivation.
Depending on version, a
corresponding message may also
appear in the Driver Information
Centre (DIC) 3 85.
Driving and operating113Notice
In the event of an accident with
airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain
time.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
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 (DIC) 3 85.
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.
114Driving and operatingCaution
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.
Caution
Fuel grades other than those listed on pages 3 125, 3 173 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of
the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
Manual transmission
To engage reverse, with the vehicle
stationary, wait 3 seconds after
depressing the clutch pedal, pull up
the collar on the selector lever and
engage the gear.
If the gear does not engage, set the
lever to neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.
Driving and operating115Caution
It is not advisable to drive with thehand resting on the selector lever.
When gearshifting is recommended
to improve fuel economy, control
indicator [ or Ò illuminates in the
Driver Information Centre (DIC) 3 80.
