Driving and operating133Starting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys and after new
disc brake pads have been fitted.
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.

Never remove the key from
ignition switch during driving as
this will cause steering wheel lock.
Power button
Electronic key must be inside the
vehicle, either in the card reader or
the front passenger compartment.
Driving and operating135These functions stop working when
the driver's door is opened and the vehicle is locked.
Note
Always take the electronic key with
you when exiting the vehicle.
The electronic key being left in the
card reader is indicated by a warning
chime 3 105 and a message in the
Driver Information Centre 3 104
when the driver's door is opened.9 Danger
Never leave an electronic key
inside the vehicle when children or animals are left in the vehicle, to
avoid unintended operation of
windows, doors or engine. Risk of
fatal injury.
Fault
If the engine cannot be started, the
cause may be one of the following:
● Fault in electronic key.
● Electronic key out of reception range.
● Battery voltage too low.
● Overload of the central locking system by operating at frequentintervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.

Starting the engine
Manual transmission: operate clutch.
Do not accelerate.
Diesel engines: turn the key to
position 2 for preheating until control
indicator ! extinguishes in the
instrument cluster 3 101.
Turn key to position 3 and release.
The increased engine speed
automatically returns to normal idling
speed as the engine temperature
rises.
Start attempts should not last longer
than 15 seconds. If engine does not
start, wait 15 seconds before
repeating starting procedure. If
necessary, depress accelerator
before repeating starting procedure.
Before restarting or to switch off the
engine, turn key back to 0.
During an Autostop, the engine can
be started by depressing the clutch
pedal.

Driving and operating137Resetting with electronic key
system
To reset the fuel cut-off system and
enable the vehicle to be driven:
1. Insert the electronic key in the card reader 3 133.
2. Press START/STOP without
depressing any pedals.
3. Wait a few minutes to allow the fuel system to be reset.

Refuelling 3 161.
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. It restarts the engine
automatically as soon as the clutch pedal is depressed.
A vehicle battery sensor ensures that
an Autostop is only performed if the
vehicle battery is sufficiently charged
for a restart.
Switch off engine and ignition before
exiting the vehicle.
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.
If the below conditions are not
fulfilled, an Autostop is prohibited and
control indicator \ illuminates in the
instrument cluster 3 102.Deactivation
Deactivate the stop-start system
manually by pressing Î. LED in the
button illuminates to indicate
deactivation and a corresponding message appears in the Driver
Information Centre 3 103.
If deactivated manually, it is possible to reactivate the stop-start system by
pressing Î again. The LED
extinguishes in the button and a
corresponding message appears in
the Driver Information Centre. The
system is reactivated automatically
the next time the ignition is switched
on.
138Driving and operatingVehicle messages 3 104.
Note
When the fast idle function is
activated, the stop-start system is
automatically deactivated and
cannot be reactivated by pressing
Î . LED in button illuminates to
indicate deactivation and a
corresponding message may
appear in the Driver Information Centre 3 103.
Idle speed control 3 136.
Depending on version, if the driver's door is opened or the driver's seat belt is unfastened, the stop-start system is
deactivated automatically, and the
engine is switched off. Restart engine by pressing START/STOP .
Power button 3 133.
Autostop
If the vehicle is at a low speed or at a standstill, activate an Autostop as
follows:
● depress the clutch pedal
● move the selector lever to neutral
● release the clutch pedalThe engine will be switched off while
the ignition stays on if the required
conditions are met.
An Autostop is indicated when Ï
illuminates in the instrument cluster
3 102.
During an Autostop, heating and brake performance will be
maintained. Brake assist, however, is
not available 3 149.
Caution
The power steering assist may be
reduced during an Autostop.
If you exit the vehicle while the engine is in an Autostop, a warning chime will
sound and a message " IGNITION
OFF " is displayed in the Driver
Information Centre as a reminder that
the engine is on standby and has not
been switched off.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited and control indicator \ will
illuminate in the instrument cluster:
● 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 outside temperature is not too
low or too high (e.g. below 0 °C
or above 35 °C)
Driving and operating139● the defrosting function is notactivated
● the climate control system does not inhibit an Autostop
● the brake vacuum is sufficient
● the self-cleaning function of the diesel particle filter is not active
3 141
● the Antilock brake system (ABS) 3 148, Traction Control system
(TC) 3 150 and Electronic
Stability Program (ESP® Plus
)
3 151 ride control systems are
not actively engaged
● the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control system may also inhibit an Autostop.
See " Climate control " chapter for
further information 3 120.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 133.Vehicle battery discharge protection
To ensure reliable engine restarts,
several battery discharge protection
features are implemented as part of
the stop-start system.
Restart of the engine by the driver
Depress the clutch pedal to restart the
engine.
Note
If any gear is selected, the clutch
pedal must be fully depressed to
restart the engine.
The engine restart may be interrupted
if the clutch pedal is released too
quickly while a gear is engaged.
If the engine does not restart first
time, depress clutch pedal fully again.
Alternatively, press button Î to
restart the engine while in an
Autostop.
Control indicator Ï 3 102
extinguishes in the instrument cluster when the engine is restarted.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 vehicle battery is discharged
● the outside temperature is too low or too high (e.g. below 0 °C
or above 35 °C)
● the defrosting function is activated 3 120
● the brake vacuum is not sufficient
● the brake pedal is operated repeatedly
● the vehicle starts to move
An automatic engine restart may not
be possible if a door or the bonnet is
open.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during engine restart may be
noticeable.
