signalslever up=right turn signallever down=left turn signal
If the lever is moved past the
resistance point, the turn signal is
switched on constantly.
When the steering wheel is turned
back, the turn signal is automatically
deactivated. This will not happen
when making a minor steering
manoeuvre such as lane changing.
For three flashes, e.g. when changing
lanes, press the lever until resistance is felt and then release. Move the
lever to the resistance point and hold
for longer indication.
The volume of the turn signal audible
warning is dependent upon vehicle
speed.
Switch the turn signal off manually by moving the lever to its original
position.

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 3 125.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.SteeringCaution
Never leave the steering wheel on
full lock when the vehicle is
stationary, as this may damage
the power steering pump.
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 2 3 87.

124Driving 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 of the
battery.

Deactivation
Deactivate the stop-start system
manually by pressing the eco button.
The deactivation is indicated when
the LED in the button extinguishes.
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 to 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,
power steering and brake
performance will be maintained.
Air conditioning system may or may
not inhibit the stop-start system
according to the cooling performance.
Caution
The steering assist can be
reduced during an Autostop.
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 or low
■ the engine exhaust temperature is not too high, e.g. after driving with
high engine load
■ the ambient temperature is not too low
■ the defrosting function is not activated
■ the climate control system does not
inhibit an engine stop
■ the brake vacuum is sufficient

128Driving and operating■ Switch off the engine and turnthe ignition key to position
LOCK , push key into ignition
switch and remove.
Turn the steering wheel until the steering wheel lock is felt to
engage.
For vehicles with automatic
transmission, depress foot
brake and shift into P before
pushing key into ignition switch
and removing.
■ If the vehicle is on a level surface or uphill slope, engage
first gear or move the selector
lever to P 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 or
move the selector lever to P
before switching off the ignition.
Turn the front wheels towards
the kerb.■ Close windows and sunroof.
■ Lock the vehicle with button p on
the radio remote control 3 21.

3 25.Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Malfunction indicator light 3 85.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification.
