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.

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.
118Driving and operating● the self-cleaning function of thediesel 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.
