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 3 157.
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.
Control indicator c 3 107.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
Driving and operating153Starting 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.
Diesel particle filter 3 160.

driving only in case of vehicle
emergency.
Starting the vehicle at low
temperatures
Starting 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.
With temperatures below -30 °C the
automatic transmission requires a
warming phase of approx. 5 minutes.
The selector lever must be in position
P .
Automatic Starter Control
This function controls the engine
starting procedure. The driver does
not need to hold the key in position 3
or to hold Engine Start/Stop pressed.
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 not operated (manual transmission).
■ Brake pedal not operated or selector lever not in P or N
(automatic transmission).
■ 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 pedal is released.
158Driving and operatingCaution
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.
■ The stop-start system is not manually deactivated.
■ The bonnet is fully closed.
■ The driver's door is closed or 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 above -5° C.
■ The climate control system allows an Autostop.
■ The brake vacuum is sufficient.
■ The self-cleaning function of the diesel particle filter is not active.
■ The vehicle was driven at least at walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 138.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 153.
Vehicle battery discharge protection
To ensure reliable engine restarts, several battery discharge protection
features are implemented as part of
the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched to a powersaving mode. The fan speed of the
climate control system is reduced to
save power.
Restart of the engine by the
driver
Depress the clutch pedal to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
