Notice
If the settings for demisting and
defrosting are selected, an Autostop will be inhibited.
If the settings for demisting and
defrosting are selected while the
engine is in an Autostop, the engine will restart automatically.
Stop-start system 3 138.
Air conditioning systemIn addition to the heating and
ventilation system, the air
conditioning system has controls for:n=cooling4=air recirculation

Cooling n
Press n to switch on cooling.
Activation is indicated by the LED in
the button. Cooling is only functional
when the engine is running and
climate control fan is switched on.
Press n again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
might inhibit Autostops.
Air recirculation system 4
Press 4 to activate air recirculation
mode. Activation is indicated by the
LED in the button.

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.

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.

140Driving and operating
■ The stop-start system is manuallydeactivated.
■ 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.Parking9 Warning
■ 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. Pull switch m for approx.
one second.
The electric parking brake is
applied when control indicator
m illuminates 3 96.
■ Switch off the engine.
■ If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector lever to position P before removing
the ignition key. On an uphill
slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position
P before removing the ignition
key. Turn the front wheels
towards the kerb.
■ Remove the ignition key. Turn the steering wheel until the
steering wheel lock is felt to
engage.
For vehicles with automatic
transmission, the key can only
be removed when the selector
lever is in position P.
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.
