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 oruntil the key is removed from the
ignition switch, regardless of whether
any door will be opened.
Starting the engine
Operate clutch.
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 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.

122Driving and operating
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.
Parking ■ Do not park the vehicle on an easily
ignitable surface. The high
temperature of the exhaust system
could ignite the surface.
■ Always apply parking brake. Apply manual parking brake without
pressing release button. Apply as
firmly as possible on downhill or
uphill slopes. Depress the foot
brake at the same time to reduce
operating force.
■ Switch off the engine and ignition. Turn the steering wheel until the
steering wheel lock engages.
■ If the vehicle is on a level surface or
uphill slope, engage first gear
before switching off the ignition. On
an uphill slope, turn the front
wheels away from the kerb.
If the vehicle is on a downhill slope, engage reverse gear beforeswitching off the ignition. Turn the
front wheels towards the kerb.
■ Lock the vehicle and activate the anti-theft alarm system.
Notice
In the event of an accident with airbag deployment, the engine is
turned off automatically if the vehicle comes to a standstill within a certain
time.

Stop-start system 3 120.
Deactivation
Press button B; LED in the button
extinguishes and a message pops-up
in the Driver Information Centre.
Each time the engine is started, City
mode is deactivated.
Overload If the steering in City mode is heavily
loaded, e.g. in long parking
manoeuvres or heavy city traffic, the
system is deactivated for overheat
protection. Steering operates in
normal mode until City mode
activates automatically.Fault
In the event of a fault in the system,
c illuminates and a message is
displayed in the Driver Information
Centre.
Vehicle messages 3 92.
System calibration
If control indicators c and a
illuminate simultaneously, a
calibration of the power steering
system is necessary. This can occur
e.g. when turning the steering wheel for one rotation with ignition switched
off. In this case switch on ignition and
turn steering wheel once from lock to
lock.
If control indicators c and a do not
extinguish after calibration, seek the
assistance of a workshop.

138Driving and operating
A brief vibration in the steering wheel
after engaging reverse gear indicates
that the steering is controlled by the
system. Then the vehicle is steered
into the slot automatically by giving
the driver detailed instructions for
braking, accelerating and gear
shifting. The driver must keep hands
away from the steering wheel.
Pay always attention on the sound of
the front-rear parking assist.
Continuous sound means that the
distance to an obstacle is less than approx. 30 cm.
If, for any reason, the driver must take over control of the steering, hold the
steering wheel only at the outer edge. Automatic steering is cancelled in thisevent.Display indication
The instructions in the display show:
■ general hints and warning messages
■ a hint when driving faster than 18 mph during parking slot
searching mode, or 5 mph in
guiding mode,■ the demand to stop the vehicle, when a parking slot is detected,
■ the direction of driving during the parking manoeuvre,
■ the demand to shift rearwards or forwards,
■ the demand to accelerate or brake,
■ for some of the instructions a progress bar is shown in the DriverInformation Centre,
■ the successful parking indicated by
a pop-up symbol and a chime,
■ the cancelling of a parking manoeuvre.Selecting of parallel or perpendicular
parking
When searching for a parking slot,
select parallel or perpendicular
parking slot by pressing SET/CLR
button on the turn signal lever.

Driving and operating139
If the system is equipped with Colour-
Info-Display, select the type of
parking slot by tapping the display
icon 6 or 7.
The display shows the type of parking
slot.
Changing the parking side
The system is configured to detect
parking slots by default on the
passenger side. To detect parking
slots on the driver side, switch on turn
indicator to the driver side for the
durance of the search.
As soon as the turn indicator is
switched off, the system searches for
parking slots on the passenger side
again.
Display priorities
After activating the advanced parking assist, a message appears in the
Driver Information Centre or Colour-
Info-Display. Advanced parking
assist indication in the Driver
Information Centre can be inhibited
by vehicle messages with a higher
priority. After approving the message
by pressing the SET/CLR button on
the turn signal lever, advanced
parking assist instructions appear
again and the parking manoeuvre can
be continued.
Deactivation
The system is deactivated by:
■ long press of button D,
■ parking manoeuvre successfully ended,
■ driving faster than 18 mph during parking slot search,
■ driving faster than 5 mph during parking guidance,
■ driver interference on steering wheel detected,
