Driving economically
ECO mode ECO mode is a function that
optimises fuel consumption. It affects
engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
Activation
Press ECO. Control indicator ECO
illuminates in the instrument cluster when activated.
Driving and operating131Starting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys and after new
disc brake pads have been fitted.
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.
Stop-start system 3 135.
Diesel particle filter 3 138.
Ignition switch positions

remain active until key is
removed or driver's door is
opened, provided the ignition was on previously1:accessory power mode: Steeringwheel lock released, some
electrical functions are operable,

Remove key from ignition switch and
turn steering wheel until it engages.9 Danger
Never remove the key from
ignition switch during driving as
this will cause steering wheel lock.
Power button
Electronic key must be inside the
vehicle, either in the card reader or
the front passenger compartment.
Driving and operating139conditions. Autostop is not available
and fuel consumption may be higher
during this period. The emission of
smells and smoke during this process
is normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and if previous driving conditions did not
enable automatic cleaning, it will be
indicated by the illumination of control
indicators F 3 98 and Z 3 98 in the
instrument cluster. 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.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on page 3 158, 3 208 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.
If control indicator Z flashes, the
permitted emission limits may be
exceeded. Lift your foot off the
accelerator until Z stops flashing and
is steadily illuminated. Contact a
workshop immediately.
Malfunction indicator light 3 98.
AdBlue
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.
158Driving and operating● ice, snow, mud, or anything elsecovers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth
● the rear doors/tailgate are not closed correctly
● the vehicle had a rear-end accident
● there are extreme temperature changesFuel
Fuel for diesel engines
Only use diesel fuel that complies
with EN 590. The fuel must have low
sulphur content (max. 10 ppm).
Equivalent standardised fuels with a
biodiesel (= FAME according to
EN14214) content of max. 7% by
volume (like DIN 51628 or equivalent
standards) may be used.
In countries outside the European
Union, use Euro-Diesel fuel with a
sulphur concentration below 50 ppm.Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and loss of
warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
The flow and filterability of diesel fuels are temperature-dependent. When
temperatures are low, refuel with
diesel fuel with guaranteed winter
properties.
Diesel fuel filter 3 171, diesel fuel
system bleeding 3 171.
Refuelling9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers.
Vehicles with stop-start system:
The engine must be switched off
and the ignition key removed, to avoid risk of engine being
restarted automatically by the
system.
Switch off any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.

● Explosive gas may be present in the vicinity of the battery.
Additional battery
Depending on the vehicle's auxiliary
equipment, certain models may have
an additional battery located under
the front passenger seat.
Note
The additional battery is
automatically connected to the main vehicle battery only when the engine
is running. It does not need to be manually disconnected before
disconnecting the main vehicle
battery or before jump starting the vehicle.
Jump starting 3 195.
Diesel fuel filter
The diesel fuel filter is accessible from the underside of the vehicle.
Drain filter of residual water at every
engine oil change.
Place a container underneath the
filter housing. Loosen the knurled
screw on the lower part of the filter by
approx. one turn, to drain off the
water.
The filter is drained as soon as water- free diesel fuel emerges. Retighten
the screw.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.
Diesel fuel system bleeding
If the fuel tank has been run dry, it will be necessary to air vent or bleed the
diesel fuel system.
Refuel then proceed as follows:
With ignition key
● Switch on the ignition (key to position 2) for five seconds at a
time.
● Switch off ignition (key to position
1 ) for three seconds.
