Remove the caps and ensure funnel
is securely located onto the filler pipe.
Ensure the funnel is replaced
securely together with both end caps
fitted.
A stabilization of the engine oil
consumption will not take place until
the vehicle has been driven several
thousand miles. Only then can the
actual degree of consumption be
established.
If consumption exceeds more than 0.5 litres every 600 miles after this
running-in period, consult a
workshop.
Capacities 3 162, Engine oil level
monitor 3 67.
Fit the cap on straight and tighten it.
Engine air filter Engine air flow indicator
On certain models, an indicator is
located in the engine induction
system and indicates if the air-intake
to the engine is restricted.
Clear=No restrictionRed tell-tale=RestrictedIf the red tell-tale is displayed when
the engine is running, consult a
workshop.
Engine coolant
The 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.
Page 122 of 173

120Vehicle care
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 illuminates red in
the instrument cluster, together with
C 3 72. Consult a workshop if
coolant level is sufficient.
Power steering fluidIf 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.
Page 123 of 173

Vehicle care121Caution
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 fluid
9 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 high-performance brake
fluid approved for your vehicle.
Brake and clutch fluid 3 147.
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.

Battery access
The vehicle battery is located beneath the front left hand seat floor
panel 3 139.
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 containssulfuric 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.
Vehicle battery maintenance9 Danger
Ensure adequate ventilation when
charging the battery. There is a
risk of explosion if gases
generated during charging are
allowed to accumulate!
Replacing the vehicle battery
When the vehicle battery is being replaced, please ensure that there
are no open ventilation holes in the
vicinity of the positive terminal. If a
ventilation hole is open in this area, it
must be closed off with a dummy cap,
and the ventilation in the vicinity of the negative terminal must be opened.
We recommend that you have the
vehicle battery replaced by a
workshop.
Additional battery
Depending on the vehicle's auxiliary
equipment certain models may have
an additional battery located next to
the vehicle battery.
Diesel fuel filter
Drain diesel fuel filter of residual
water at every engine oil change.
Page 125 of 173

Vehicle care123
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. Remove the protective cover from
the in-line supply pump.
2. Place a suitable container underneath the fuel filter vent
screw to collect fuel.
3. Loosen the vent screw (arrowed) by one turn.
4. Manually operate the in-line supply pump slowly and steadily
until fuel discharging from the
loosened vent screw is free of air
bubbles.
5. Retighten the vent screw.
6. Refit the protective cover to the in-
line supply pump.Wiper blade replacement
