operation 3 times or more while theengine is switched off, to avoid air
entering the fuel line.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.
If there is water in the diesel fuel filter, control indicator U illuminates in the
instrument cluster 3 89. Drain the
water immediately.
Diesel fuel system
bleeding
If the fuel 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. If the engine will not start, wait at least 10 seconds before trying
again. If the engine fails to start, seek the assistance of a workshop.Wiper blade replacement
Wiper blades on the windscreen

retaining clip 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

Tyre pressureCheck 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.
Use the valve cap key to make
unscrewing the valve caps easier.
The valve cap key is located on the
inside of the tank flap.
Tyre pressure 3 207.
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.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
The tyre pressure tables show all
possible tyre combinations 3 207.
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.
If the tyre pressure shall be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Tyre pressure monitoring
system The tyre pressure monitoring system
checks the pressure of all four wheels
once per minute when vehicle speed
exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure. If
wheels without sensors are mounted,
the tyre pressure monitoring system
is not operational. Retrofitting of
sensors is possible.
Notice
In countries where the tyre pressure monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.

Use unleaded Premium fuel only for the following countries: Armenia, Azerbaijan, Belarus, Moldova.
3) Use of 91 RON fuel reduces power and torque. If no unleaded Premium fuel is available, 91 RON can be used, taking care to avoid high engine load or
full load as well as driving in mountainous terrain with a trailer load or high payload.
