Driving and operating133Caution
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 3 135.
Diesel particle filter 3 141.

Driving and operating141Engine 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
harmful 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 A 3 96. 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 3 167, 3 225 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.

168Driving and operatingdiesel, 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 3 182, diesel fuel
system bleeding 3 183.
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 on 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.
Caution
In case of misfuelling, do not
switch on ignition.
The fuel tank filler neck with bayonet
cap is located on the left front side of
the vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked and the door is opened. Open the fuel filler flap by
hand.9 Danger
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.

182Vehicle careMeaning of symbols:● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulfuric acid which could cause
blindness or serious burn
injuries.
● See the Owner's Manual for further information.
● 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 mounted under
the right-hand front seat.
Notice
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.
The terminals are designed for
additional electrical consumers up to
a maximum of 50 A.
Jump starting 3 212.
Diesel fuel filter
Drain diesel fuel filter of residual
water at every engine oil change.
Place a container underneath the
filter housing. Loosen the knurled
screws on the filter cover and on the
lower part of the filter by approx. one
turn, to drain off the water.

Vehicle care183The filter is drained as soon as diesel
fuel emerges from the knurled screw
at the bottom. Retighten the two
screws.
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 willbe necessary to air vent or bleed the
diesel fuel system.
Fill the tank with fuel and proceed as
follows:
1. Place a suitable container underneath the fuel filter vent
screw to collect fuel.
2. Loosen the vent screw (arrowed) by one turn.
3. Manually operate the in-line supply pump slowly and steadily
until fuel discharging from the
loosened vent screw is free of air
bubbles.
4. Retighten the vent screw.
In vehicles without an in-line supply
pump, fill the tank with fuel and
proceed as follows:Caution
Do not turn ignition key to position 3 before beginning the bleeding
procedure.
Ignition switch positions 3 133.
1. Turn ignition key to position 2 and
hold for five seconds.
2. Turn key back to position 1 and
wait for three seconds.
3. Repeat Step 1 and 2 multiple times.
4. Turn key to position 3, then return
to 0.
If the engine cannot be started after
several attempts to bleed the diesel
fuel system, seek the assistance of a
workshop.
Wiper blade replacement
Wiper blades on the windscreen If required, use the step located below
the headlights to reach the
windscreen wiper.
