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 3 106.
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 in the Driver
Information Centre.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.

104Driving and operatingUse only floor mats, which fit properly
and are fixed by the retainers on the
driver side.
Driving downhill
Engage a gear when driving downhill to ensure that sufficient brake
pressure is available.
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 70.Caution
Vehicle equipped with electric
power steering:
If the steering wheel is turned until it reaches the end of its travel and
is held against that position for an
extended period of time, power
steering assistance may be
reduced.
If the steering assistance is used
for an extended period of time,
power assistance may be
reduced.
Power steering assistance should
return back to normal when the
system has cooled down.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.
Autostop may be inhibited to allow for
charging of the vehicle battery.
Ignition switch positions
Turn key:

106Driving and operatingBefore 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 control This 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 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.
Stop-start system
The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, itswitches 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.
On vehicles with manual
transmission, the engine is started automatically as soon as the clutch is depressed.
On vehicles with manual transmission
automated, the engine is started
automatically as soon as the brake
pedal is released.
A vehicle battery sensor ensures that
an Autostop is only performed if the
vehicle 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.

Driving and operating107Deactivation
Deactivate the stop-start system
manually by pressing Ï. The
deactivation is indicated when the
LED in the button extinguishes.
Autostop
Vehicles with manual transmission
If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● Depress the clutch pedal.
● Set the lever in neutral.
● Release the clutch pedal.The engine will be switched off while
the ignition stays on.Vehicles with manual transmission
automated
If the vehicle is at a standstill with the brake pedal depressed, Autostop is
activated automatically.
The engine will be switched off while
the ignition stays on.
The stop-start system will be disabled
on inclines of 15% or more.
Indication
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
During an Autostop, the heating and
brake performance 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 climate control system allows an Autostop.

108Driving and operating● The brake vacuum is sufficient.
● 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 further
information 3 97.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 104.
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, e.g., the rear window
heating, are disabled or switched into 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
Depress the clutch pedal to restart the
engine.
If the selector lever is shifted out of
neutral before depressing the clutch
pedal first, control indicator -
illuminates or is shown as a symbol in
the Driver Information Centre.
Control indicator - 3 69.Vehicles with manual transmission
automated
Release the brake pedal or move
selector lever out of D to restart the
engine.
Restart of the engine by the stop-
start system
The selector lever must be in neutral
to enable an automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system:
● The stop-start system is manually deactivated.
● The bonnet is opened.
● The driver's seat belt is unfastened and the driver's door
is opened.
● The engine temperature is too low.
● The charging level of the vehicle battery is below a defined level.
● The brake vacuum is not sufficient.
● The vehicle is driven at least at walking speed.
● The climate control system requests an engine start.
● The air conditioning is manually switched on.
If the bonnet is not fully closed, a warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during restart might be noticeable.
