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 3 138.
Idle boost
If charging of the vehicle battery is
required due to vehicle battery
condition, the power output of the
generator must be increased. This will be achieved by an idle boost which
may be audible.
On vehicles with Uplevel-Display or
Uplevel-Combi-Display, 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.
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 a higher
or lower steering effort.
Control indicator c 3 97.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.
136Driving and operatingStarting 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
vehicle battery.

Retained power off
The following electronic systems can
work until the driver's door is opened
or at the latest for 10 minutes after the
ignition is switched off:
■ power windows
■ power outlets
Power to the Infotainment system will continue to operate for 30 minutes or
until the key is removed from the
ignition, regardless of whether any
door is opened.
Starting the engine
Manual transmission: operate clutch.
Automatic transmission: operate
brake and move the selector lever to
P or N.
Do not operate accelerator pedal.
Driving and operating137
Diesel engine: turn the key to position2 for preheating until control
indicator ! extinguishes.
Turn the key briefly to position 3 and
release: an automatic procedure operates the starter with a short delay
as long as the engine is running, see
Automatic Starter Control.
Before 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 -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
needs 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 have 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 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 is released.
138Driving and operatingStop-start systemThe 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. It starts the engine
automatically as soon as the clutch is depressed. 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.Deactivation
Deactivate the stop-start system
manually by pressing eco. The
deactivation is indicated by the LED
in the button extinguishing.
Autostop 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.
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.
Caution
The steering assist will be reduced during an Autostop.
Driving and operating139
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 defrost selection does not inhibit an Autostop.
■ 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.
An Autostop may become less
available as the ambient temperature
approaches the freezing point.
Certain settings of the climate control
system may inhibit an Autostop. See
" Climate control " chapter for further
information 3 128.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 136.
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 into a power
saving 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.
If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates
or is shown as a symbol in the Driver Information Centre.
Control indicator - 3 96.
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.
