depending on version, a
corresponding warning message may also appear in the Driver InformationCentre 3 88.
To reset the fuel cut-off system and
enable the vehicle to be driven, refer
to " Vehicle shutdown " 3 112.Trip computer
The trip computer provides
information on driving data, which is
continually recorded and evaluated electronically.

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 3 113.
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.
Driving and operating111Caution
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
vehicle battery.

Starting the engine
Manual transmission: operate clutch
and brake.
Manual transmission automated: operate brake, the transmission
automatically shifts to N (neutral)
Do not operate the accelerator pedal.
112Driving and operatingDiesel engine: turn the key to position1 for preheating until control
indicator ! extinguishes.
Turn the key briefly to position 2 and
release.
Before restarting or to switch off the
engine, turn the 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 3 113.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.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 InformationCentre 3 88.
Generic warning control indicator 9
3 79.
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 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 3 111.
2. Fully actuate the right turn signal light 3 99.
3. Deactivate the right turn signal light.
114Driving and operatingAutostop
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 88.
During an Autostop, the heating,
power steering and brake
performance will be maintained.
Caution
The 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
● the self-cleaning function of the diesel particle filter is not active
● the vehicle has moved since the last Autostop
● the brake vacuum is sufficient ● the windscreen wipers are not operating at fast speed
● reverse gear is not selected
● heated rear window is not operating
Ambient temperature near to the
freezing point can inhibit an
Autostop.
For manual transmission automated
vehicles, an Autostop may be
inhibited until a speed of approx.
6 mph is reached.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 111.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
