136Driving and operatingCaution
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.
Starting 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 3 138.
Diesel particle filter 3 144.
Ignition switch positions Turn key:0:ignition off: Some functions
remain active until key is
removed or driver's door is
opened, provided the ignition was
on previously1:accessory power mode: Steering wheel lock released, some
electrical functions are operable,
ignition is off2:ignition is on, diesel engine is
preheating. Control indicators
illuminate and most electrical
functions are operable3:engine start: Release key after

144Driving and operatingEngine exhaust9Danger
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.
Diesel particle filter
The diesel particle filter system filters
soot particles out of the exhaust
gases. The system includes a self-
cleaning function that runs
automatically during driving without
any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
conditions. 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 illumination of control
indicator j 3 99. 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 3 172 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.
Driving and operating173Diesel fuel that meets standard
EN16734 mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 10% Fatty Acid
Methyl Ester).
If travelling in countries outside the
European Union, occasional use of
Euro-Diesel fuel with a sulphur
concentration below 50 ppm is
possible.Caution
Frequent usage of diesel fuel containing more than 15 ppm
sulphur will cause severe engine
damage.
Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your 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. Do not use additives.
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 3 187.
Diesel fuel system bleeding 3 188.
Low temperature operation
At temperatures below 0 °C, some
diesel products with biodiesel blends
may clog, freeze or gel, which may
affect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0 °C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20 °C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor starting or damage to the fuel
injection system.Refuelling9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
A label with symbols at the fuel filler
flap is indicating the allowed fuel
types. In Europe the pump nozzles of
the filling stations are marked with
these symbols. Refuel only the
allowed fuel type.
