Headlights when driving abroad
The asymmetrical headlight beam
extends visibility at the edge of the
road on the passenger side.
However, when driving in countries
where traffic drives on the opposite
side of the road, have the headlights adjusted to prevent dazzling of

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

The settings of certain electronic
systems are adapted to reduce fuel
consumption:
● The engine reacts less quickly to
the accelerator pedal.
● Automatic upshift points occur sooner and downshift points
occur later.
● The transmission locks itself to the engine at cruising speeds, to
improve efficiency and increase
power and torque.
● The fuel supply is automatically cut-off more quickly during
vehicle deceleration. Overrun
cut-off 3 126.
Do not use fuel economy mode whilst towing, e.g. a trailer.Deactivation

Control of the vehicle
Never 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.

130Driving and operatingIf cleaning of the filter is required andprevious driving conditions did not
enable automatic cleaning, it will be
indicated by control indicator %

% illuminates, accompanied by a
warning chime, when diesel particle
filter is full. Start cleaning process as
soon as possible.
% flashes when diesel particle filter
has reached the maximum filling level. Start cleaning process
immediately to avoid damage to the
engine. A warning chime sounds
every 3 minutes until the cleaning
process is complete.
Cleaning process To activate the cleaning process,
continue driving, keeping engine
speed above 2000 revolutions per
minute. Shift down if necessary.
Diesel particle filter cleaning is then
started.
If control indicator Z illuminates
additionally in the instrument cluster
when the engine is running, there
may be a fault in the diesel particlefilter 3 84. Cleaning is not possible,
seek the assistance of a workshop
immediately.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
Do not switch off the engine until the
cleaning process is complete. This is
indicated by the extinguished control
indicator %.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed 3 207 could damage the catalytic
converter or electronic
components.
Unburnt fuel will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
Malfunction indicator light 3 84.
Driving and operating131AdBlue
General information
The selective catalytic reduction
(BlueInjection) is a method to
substantially reduce the nitrogen
oxides in the exhaust emission. This
is achieved by injecting a Diesel
Exhaust Fluid (DEF) into the exhaust
system.
The designation of this fluid is AdBlue Ⓡ. It is a non-toxic, non-flammable,
colourless and odourless fluid which
consists of 32% urea and 68% water.
Note
AdBlue Ⓡ is a registered trademark
of the Verband der
Automobilindustrie e.V. (VDA).9 Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.
Caution
Avoid contact of the paintwork with AdBlue.
In case of contact, rinse off with water.
AdBlue freezes at a temperature of
approx. -11 °C. As the vehicle is
equipped with an AdBlue pre-heater,
the emissions reduction at low
temperatures is ensured. The AdBlue
pre-heater works automatically.
The typical AdBlue consumption is
approx. two litres per 1000 km, but
can also be higher depending on
driving behaviour (e.g. high load or
towing).
Level warnings
If the AdBlue level falls below a
certain value, a level warning (e.g.
"AdBlue Range: 2400 km") will be
shown in the Driver Information
Centre 3 91, located in the centre of
the instrument cluster.
Refill the tank with a volume of at least
10 litres of AdBlue as soon as
possible. Refer to " Refilling AdBlue"
below.
Driving is possible without any
restrictions.

The automatic transmission permits
automatic gearshifting (automatic
mode) or manual gearshifting
(manual mode).
