Control of the vehicleNever 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 3 105.
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.Caution
Never leave the steering wheel on
full lock when the vehicle is
stationary, as this may damage
the power steering pump.
Driving and operating103Starting 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.

-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.

The steering assist can 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 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.
