The brake fluid level must be betweenthe MIN and the MAX marks.
If fluid level is below MIN seek the
assistance of a workshop.
Brake and clutch fluid 3 218.
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
four 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.

Replacing the vehicle battery
Notice
Any deviation from the instructions
given in this section may lead to
temporary deactivation or
disturbance of the stop-start system.
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.
Only use vehicle batteries that allow the fuse box to be mounted above the
vehicle battery.
Ensure that the battery is always replaced by the same type of battery.
We recommend that you have the
vehicle battery replaced by a
workshop.
Stop-start system 3 138.

184Vehicle careCharging the vehicle battery9Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed
14.6 volts when using a battery
charger. Otherwise the vehicle
battery might be damaged.
Jump starting 3 209.
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 sulphuric 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 vehicle battery.
Diesel fuel system bleeding If the tank has been run dry, the diesel
fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of 40 seconds. Repeat this process after
no less than 5 seconds. If the engine fails to start, seek the assistance of a
workshop.Wiper blade replacement
Lift the wiper arm, press button to
disengage the wiper blade and
remove.
Attach the wiper blade slightly angled
to the wiper arm and push until it
engages.
Lower wiper arm carefully.

2. Lift wiper blade.
3. Press slider holder pin.
4. Pull wiper blade out.Bulb replacement
Switch off the ignition and turn off the
relevant switch or close the doors.
Only hold a new bulb at the base. Do not touch the bulb glass with bare
hands.
Use only the same bulb type for
replacement.
Replace headlight bulbs from within
the engine compartment.
Notice
After driving in heavy rain or after
washing, some exterior light lenses
could appear frosty.
This condition is caused by the
temperature difference between the
inside and outside of the light.
This is similar to the condensation
on your windows inside your vehicle
during the rain and doesn't indicate
a problem with your vehicle.
If the water leaks into the light bulb
circuitry, have the vehicle checked
by your authorised workshop.

190Vehicle careElectrical systemFuses
Data on the replacement fuse must
match the data on the defective fuse.
In a box above the positive terminal of
the battery are some main fuses. If
necessary have them changed by a
workshop.
Before replacing a fuse, turn off the respective switch and the ignition.
A blown fuse can be recognised by its melted wire. Do not replace the fuse
until the cause of the fault has been
remedied.
Some functions are protected by
several fuses.
Fuses may also be inserted without existence of a function.
Notice
Not all fuse box descriptions in this
manual may apply to your vehicle.
When inspecting the fuse box, refer
to the fuse box label.Fuse extractor
A fuse extractor may be located in the fuse box in the engine compartment.
Place the fuse extractor on the
various types of use from the top or
side, and withdraw fuse.

198Vehicle careNotice
In countries where the tyre pressure monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle operating permit.
The current tyre pressures can be
shown in the Driver Information
Centre.
Midlevel display:
Select the Tyre pressure page under
the Vehicle Information Menu ? in
the Driver Information Centre 3 97.
Uplevel display:
Select the Tyre pressure page under
the Info Menu in the Driver
Information Centre 3 97.
System status and pressure warnings
are displayed by a message
indicating the corresponding tyre in
the Driver Information Centre.
The system considers the tyre
temperature for the warnings.
Temperature dependency 3 196.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 95.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 232.
If w flashes for 60-90 seconds and
then illuminates continuously, there is
a fault in the system. Consult a
workshop.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after driving, this
could be an indicator for approaching a low tyre pressure condition. Check
tyre pressure.
Vehicle messages 3 103.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
