Battery voltage
Midlevel-DisplayWhen the vehicle battery voltage is
running low, a warning code 174 will
appear in the Driver Information
Centre.

When the vehicle battery voltage is running low, a warning message will
appear in the Driver Information
Centre.
1. Switch off immediately any electrical consumers which are
not required for a safe drive, e.g.
seat heating, heated rear window or other main consumers.
2. Charge the vehicle battery by driving continuously for a while or
by using a charging device.
The warning message or warning
code will disappear after the engine
has been started twice consecutively
without a voltage drop.
If the vehicle battery cannot be
recharged, have the cause of the fault
remedied by a workshop.Vehicle personalisation

To prevent discharge of the vehicle
battery when driving, following
systems are reduced automatically in two stages and finally switched off:
● auxiliary heater
● heated rear window
● heated mirrors
● heated seats
● fan
In the second stage a message which
confirms the activation of the vehicle
battery discharge protection will be
displayed in the Driver Information
Centre.Switching off electric lights

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 3 126.
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 on the Uplevel-
Display.
Pedals To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
124Driving and operatingUse only floor mats, which fit properly
and are fixed by the retainers on the
driver side.
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 85.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 the vehicle battery.Ignition switch positions0:ignition off1:steering wheel lock released,
ignition off2:ignition on3:starting
Retained power off
The following electronic systems can
work until the driver's door is opened
or at the latest for ten minutes after
the ignition is switched off:
● power windows
● power outlets
● power sunroof
Driving and operating125Power to the Infotainment system will
continue to operate for 30 minutes or until the key is removed from theignition switch, regardless of whether any door is opened.
Starting the engine
Turn key to position 1
to release the
steering wheel lock.
Manual transmission: operate clutch
and brake pedal.
Manual transmission automated:
operate brake pedal.
Do not operate the accelerator pedal.
Turn key briefly to position 3 and
release: an automatic procedure operates the starter after a brief
delay, until 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 -30 °C . Required is an engine oil with
the correct viscosity, the correct fuel,
performed services and a sufficiently
charged vehicle battery.
Automatic starter controlThis 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 engineis running. Because of the checking
procedure, the engine starts running after a short delay.
Possible reasons for a non-starting engine:
● clutch pedal is 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.
126Driving 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.
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.Deactivation
Deactivate the stop-start system
manually by pressing eco. 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
depressed brake pedal, 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.
Driving and operating127During 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.● 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 more
details 3 116.
Immediately after motorway driving,
an Autostop may be inhibited.
New vehicle running-in 3 124.
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.
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 84.Vehicles with manual transmission
automated:
Release the brake pedal or move
selector lever out of D to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
Restart of the engine by the stop-
start system
The selector lever must be in neutral
to enable an automatic restart.
