driving only when required in case of 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.
five 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

Driving and operating161starting 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).
● 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 pedal 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 the 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. The ignition stays on.
The engine switches on automatically
when certain conditions apply or
restart is activated by a driver.
Activation The stop-start system is available assoon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.Deactivation
Deactivate the stop-start system
manually by pressing D. The
deactivation is indicated when the
LED in the button illuminates.
Autostop
Vehicles with manual transmission
Depending on the engine, two
versions of an Autostop are available. See engine data to identify the engine
identifier code for your vehicle
3 286.
Conventional Autostop
All engines except B16DTU have only
the conventional Autostop.

162Driving and operatingAn Autostop can be activated at a
standstill or at a speed lower than
3 mph.
Activate a conventional Autostop as
follows:
● Depress the clutch pedal.
● Set the lever in neutral.
● Release the clutch pedal.
Early Autostop
Only the engine B16DTU has early
Autostop in addition to conventional
Autostop.
An Autostop, both conventional and
early, can be activated at a speed
lower than 9 mph.
Early Autostop is inhibited if the
incline is greater than 5%.
Activate an early Autostop as follows: ● Depress the brake pedal sufficiently.
● Depress the clutch pedal.
The engine will be switched off while
the ignition stays on.Early Autostop is inhibited when the
turn signal is on, trailer hitch is
connected, the steering wheel is
moved beyond a certain point or the
inclines is greater than 5%.Vehicles with automatic transmission
or manual transmission automated
If the vehicle is at a standstill with
depressed brake pedal, Autostop is
activated automatically.
Indication
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
After restart, the idle speed is
indicated.
During an Autostop the performance
of the vehicle will be maintained.
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 brake vacuum is sufficient.
● Between the last Restart and a new Autostop must be about
10 s.

Driving and operating163● The self-cleaning function of theexhaust filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
The stop-start system will be
deactivated on inclines of 12% or
more.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 146.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 156.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle 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 aredisabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to save power.
Restart of the engine by the driverVehicles with manual transmission
Depending on the engine, two
versions of a restart are available.
