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.
Stop-start system 3 121.
Idle boost If charging of the vehicle battery is
required due to battery condition, the
power output of the generator has to
be increased. This will be achieved by
an idle boost which may be audible.
On vehicles with Uplevel-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.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.

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.

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.

128Driving and operating
ESC is operational after each engine
start as soon as the control indicator
b extinguishes.
When ESC operates b flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Fault
If there is a fault in the system the
control indicator b lights up
continuously and a message or a
warning code appears in the Driver
Information Centre. The system is not
operational.
Have the cause of the fault remedied
by a workshop.
City mode City mode is a feature which enables
increased steering assistance during
lower speed conditions, e.g. city
traffic or parking. Steering assistance
is increased for greater convenience.Activation
Press button B when engine is
running. The system works from
standstill up to 22 mph, and in reverse gear. Above this speed the system
changes to normal mode. When
activated, City mode engages
automatically below 22 mph.
An illuminated LED in the City mode
button indicates that the system is
active and a message pops-up in the
Driver Information Centre.
City mode remains active during an
Autostop, but is only operational
when the engine is running.

Stop-start system 3 121.
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 93.
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.

136Driving and operating
In the Driver Information Centre, the
distance to a front and rear obstacle
is displayed by changing distance
lines.
In the Colour-Info-Display, distance is displayed by coloured zones in front
of or behind the vehicle.
The distance 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, distance
indication appears again.
Fault
In the event of a fault or if the system
does not work temporarily, e.g.
because of high external noise level
or other interference factors, the LED in the button flashes for 3 seconds
and then extinguishes. Control
indicator r illuminates in the
instrument cluster 3 85 and a
message pops-up in the Driver
Information Centre.
Vehicle messages 3 93.Advanced parking assist9 Warning
It is the driver who bears full
responsibility for accepting the
parking slot suggested by the
system and the parking
manoeuvre.
Always check the sourrounding
area in all directions when using
advanced parking assist.
The advanced parking assist
measures a suitable parking slot
while passing, calculates the
trajectory and automatically steers
the vehicle into a parallel or
perpendicular parking slot.
Instructions are given by the Driver
Information Centre or the Colour-Info-
Display supported by acoustic
signals. The driver must control
acceleration, braking and gear
shifting, while steering is done
automatically.
Advanced parking assist can only be
activated when driving forwards.
