Vehicle care135Engine coolantThe coolant provides freeze
protection down to approx. -28 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be just above the
MIN mark. Top up if the level is low.9Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
Top up with antifreeze. If no
antifreeze is available, use clean tap
water or distilled water. Install the cap
tightly. Have the antifreeze
concentration checked and have the
cause of the coolant loss remedied by a workshop.
If a substantial amount of coolant is
required, it will be necessary to bleed
any trapped air from the cooling
system. Seek the assistance of a
workshop.
If the coolant temperature is too high, control indicator W 3 84 illuminates
red in the instrument cluster, together
with C 3 82. Consult a workshop if
coolant level is sufficient.
Power steering fluidCaution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap or from
entering the reservoir.
The power steering fluid reservoir is located below the front wheel arch,
behind a trim panel.
The fluid level normally does not need
to be checked. If an unusual noise is
heard during steering or if the power
steering reacts conspicuously, seek
the assistance of a workshop.

136Vehicle care
If the fluid level in the reservoir falls
below the MIN mark consult a
workshop.
Washer 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.
Brakes
A squealing noise indicates that the
brake lining is at its minimum
thickness. Continued driving is
possible but have the brake lining
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.
Page 139 of 189

Vehicle care137
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 high-performance brake
fluid approved for your vehicle.
Brake fluid 3 166.
Vehicle battery
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.
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.
Warning label

■ 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.
Charging the vehicle battery9 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 3 159.
Replacing the vehicle battery
Have the vehicle battery replaced by
a workshop.
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
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: ■ Switch on the ignition (key to position M) for 5 seconds at a time.
■ Switch off ignition (key to position A) for 3 seconds.
■ Repeat this process multiple times.
■ Start the engine (key to position D)
then switch off (key to position St).
If the engine fails to start, seek the
assistance of a workshop.
