182Vehicle care
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 3 213.
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 98.
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.
9 Danger
Ensure the ignition is switched off
completely (the vehicle must not
be in an Autostop) before
connecting or disconnecting the
vehicle battery.

Battery discharge protection 3 116.
Battery access
The battery is located behind a panel in the front left-hand door step.
Remove the panel to access the
battery.
Vehicle care183Replacing the vehicle batteryEnsure that the battery is always
replaced by the same type of battery.
Seek the assistance of a workshop to
have the vehicle battery replaced.

Charging the vehicle battery9 Warning
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.
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 3 213.
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.
● See the Owner's Manual for further 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 right-hand front seat.
Note
The additional battery is
automatically connected to the main vehicle battery only when the engine
is running. It does not need to be
184Vehicle caremanually disconnected before
disconnecting the main vehicle
battery or before jump starting the vehicle.
The terminals are designed for
additional electrical consumers up to a maximum of 50 A.

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.
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 3 135.
Vehicle care1851.Turn ignition key to position 2 and
hold for five seconds.
2. Turn key back to position 1 and
wait for three 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.
Wiper blade replacement Wiper blades on the windscreen
If required, use the step located below
the headlights to reach the
windscreen wiper.
Lift wiper arm, press retaining clip
towards wiper arm and detach wiper
blade.
Attach the wiper blade slightly angled
to the wiper arm and push until it engages.
Lower wiper arm carefully.
Bulb replacement
Ensure the ignition is switched off
completely (the vehicle must not be in
an Autostop 3 137) 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.
Bulb check After a bulb replacement, switch on
the ignition, operate and check the
lights.

Vehicle care201Choose a tyre appropriate for the
maximum speed of your vehicle.
The maximum speed is achievable at
kerb weight with driver (75 kg) plus
125 kg payload. Optional equipment
could reduce the maximum speed of
the vehicle.
Directional tyres Fit directional tyres such that they rollin the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
The tyre pressure information label
on the driver's door frame indicates
the original equipment tyres and the
correspondent tyre pressures.
Always inflate tyres to the pressures
shown on the label.
Tyre pressures 3 247.The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 228.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 247.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Temperature dependency
Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
Tyre pressure values provided on the
tyre information label and tyre
pressure chart are valid for cold tyres, which means at 20 °C. The pressure
increases by nearly 10 kPa (0.1 bar)
Vehicle care203approaching a low tyre pressure
condition. Check tyre pressure of all
four tyres.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise w flashes for
several seconds then illuminates
continuously together with control
indicator A 3 98 and a
corresponding message appears in
the Driver Information Centre.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these wheels. For the further three
wheels, the tyre pressure monitoring
system remains operational.
Control indicator w and the
corresponding message appears at
each ignition cycle until the tyres are
inflated to the correct tyre pressure.

Relearn functionAfter a puncture has been repaired
and the driver has inflated the tyres to
the correct tyre pressure, the tyre
pressure monitoring system needs to recalculate.
Tyre pressure 3 247, Tyre repair kit
3 205.
During driving, select the tyre
pressure menu in the Driver
Information Centre by pressing button
on end of wiper lever. Press and hold button for approx. five seconds to
initialise recalculation. A
corresponding message appears in
the Driver Information Centre.
Several minutes of driving at a speed above 40 km/h may be required to
complete the relearn process. The system can only provide limited
information during this time.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is displayed in the Driver Information
Centre.
