Control of the vehicle Never coast with engine not
running
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.
Stop-start system 3 131.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must
be increased. This will be achieved by
an idle boost which may be audible.
A message appears on the Uplevel
Display.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Driving and operating129Use only floor mats, which fit properly
and are fixed by the retainers on the
driver side.
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.
Control indicator c 3 89.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 exhaust filter may take place more
often.

Retained power off
The following electronic systems can
work until the driver's door is opened
or at the latest for 10 minutes after the
ignition is switched off:
● power windows
● power outlets
● power sunroof
130Driving and operatingStarting the engine
Turn key to position 1 to release the
steering wheel lock.
Manual transmission: operate clutch
and brake pedal.
Manual transmission automated:
operate brake pedal.
Do not operate the accelerator pedal. Turn key briefly to position 3 and
release: an automatic procedure
operates the starter after a brief
delay, until the engine is running. See
'Automatic Starter Control'.
Before restarting or to switch off the
engine, turn the key back to position
0 .
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Starting the vehicle at low
temperatures
The start of the engine without
additional heaters is possible down to -30 °C . Required is an engine oil with
the correct viscosity, the correct fuel,
performed services and a sufficiently
charged vehicle battery.
Automatic starter controlThis function controls the engine
starting procedure. The driver does
not need to hold the key in position 3.
Once applied, the system will go on
starting automatically until the engine
is running. Because of the checking
procedure, the engine starts running after a short delay.Possible reasons for a non-starting
engine:
● clutch pedal is not operated (manual transmission).
● brake pedal not operated (manual transmission
automated).
● timeout occurred.
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 is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.
