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.

Vehicle care159Washer fluid
Fill with clean water mixed with a
suitable quantity of windscreen
washer fluid which contains
antifreeze.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Use of washer fluid containing
isopropanol can damage exterior
lamps.
Brakes
In 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.
Brake and clutch fluid 3 196.
Vehicle battery
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the

160Vehicle carebattery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
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
4 weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
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 access
The battery is located behind a panel in the front left-hand door step.
Remove the panel to access the
battery.
Charging the vehicle battery
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 3 188.
Warning label
Meaning 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.

Vehicle care161● See the Owner's Manual forfurther 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 front seat.
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.
The 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 bleedingIf 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.
If the engine cannot be started after
several attempts to bleed the diesel
fuel system, seek the assistance of a
workshop.
