90Instruments and controls
Depending on vehicle, an additional
outlet may be located in the rear of the
vehicle.
Connecting electrical accessories
while the engine is off will discharge
the vehicle battery. Do not exceed the
maximum power consumption of
120 W.
9 Danger
To avoid the risk of fire, if multiple
power outlets are used
simultaneously, the total power
consumption of connected
accessories must not exceed
180 W.
With ignition off the power outlet may
be deactivated.
Additionally, the power outlet may be
deactivated in case of low battery
voltage.
Electrical accessories that are
connected must comply with the
electromagnetic compatibility
requirements laid down in
DIN VDE 40 839.Caution
Do not connect any current- delivering accessories, e.g.
electrical charging devices or
batteries.
Do not damage the outlets by
using unsuitable plugs.
USB socket
In the Infotainment unit (or on the
instrument panel) there is a USB
socket M for the connection of external
audio sources and for charging
devices.
Notice
The sockets must always be kept
clean and dry.

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.

Vehicle care185BrakesIn the event of minimum thickness ofthe brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake linings replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and MAX marks.
When topping up, ensure maximum cleanliness as contamination of the
brake fluid can lead to brake system
malfunctions. Have the cause of the
loss of brake fluid remedied by a
workshop.
Only use brake fluid approved for
your vehicle.

Vehicle battery
The jump start terminal is located in
the engine compartment.
Jump starting 3 217.
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Control indicator p illuminates if
there is a fault with the charging
system. Stop, switch off engine and
seek the assistance of a workshop.
Charging system 3 99.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
186Vehicle care9Danger
Ensure the ignition is switched off
completely (the vehicle must not
be in an Autostop) before
connecting or disconnecting the
vehicle battery.
Stop-start system 3 138.
The anti-theft alarm siren must be
deactivated as follows: Switch the ignition on then off, disconnect the
vehicle's battery within 15 seconds.
Battery discharge protection 3 117.
Battery access
The battery is located behind a panel in the front left-hand door step.
Remove the panel to access the
battery.
Replacing the vehicle battery Ensure that the battery is always
replaced by the same type of battery.
Seek the assistance of a workshop to
have the vehicle battery replaced.
Stop-start system 3 138.
Charging the vehicle battery9 Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed 14.6 V
when using a battery charger.
Otherwise the vehicle battery may be damaged.
9 Danger
Ensure adequate ventilation when
charging the battery. There is a
risk of explosion if gases
generated during charging are
allowed to accumulate!
Jump starting 3 217.
Warning label
188Vehicle careThe filter is drained as soon as dieselfuel 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 will be 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 3 136.
1. Turn ignition key to position 2 and
hold for 5 seconds.
2. Turn key back to position 1 and
wait for 3 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.
