When the engine is off,
considerably more force is needed
to brake and steer. During an
Autostop the brake servo unit will still be operational.
Do not remove ignition key until
vehicle is stationary, otherwise the steering wheel lock could engage
unexpectedly.
Check oil level before seeking the
assistance of a workshop 3 143.

the fuel cut-off switch is triggered and,
depending on version, a
corresponding warning message may also appear in the Driver InformationCentre 3 90.
To reset the fuel cut-off system and
enable the vehicle to be driven, refer
to " Vehicle shutdown " 3 115.Trip computer

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 3 116.
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.
114Driving and operatingSteeringIf 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. Diesel particle filter
3 120.
Autostop may be inhibited to allow for charging of the vehicle battery. Stop-start system 3 116.

Driving and operating115Steering wheel lockRemove 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 3 116.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 operating117Deactivation
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, e.g.
Start&Stop disconnected , may also
be displayed in the Driver Information
Centre 3 90.
Autostop
If the vehicle is at a low speed or at a standstill, activate an Autostop as
follows:
● depress the clutch pedal
● set the lever to neutral
● release the clutch pedal
The engine will be switched off while the ignition stays on.
An Autostop is indicated when control
indicator ^ flashes in the Driver
Information Centre 3 90.
During an Autostop, the heating,
power steering and brake
performance will be maintained.
Caution
The power steering assist may be
reduced during an Autostop.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
Otherwise an Autostop will be
inhibited.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
● the driver's door is closed and the
driver's seat belt is fastened
● the vehicle battery is sufficiently charged and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high
● the engine exhaust temperature is not too high, e.g. after driving
with high engine load
● the ambient temperature is not too low
● the climate control system allows
an Autostop
