Closing
Lower the bonnet and let it fall into the latch from a low height (20-25 cm).
Check that the bonnet is engaged.
Caution
Do not press the bonnet into the
latch to avoid dents.
Air intake 3 120.
Engine oil
Check the engine oil level manually
on a regular basis to prevent damage
to the engine.
Ensure that the correct specification
of oil is used. Recommended fluids
and lubricants 3 202.
The maximum engine oil
consumption is 0.6 litres per
1000 km.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 5 minutes.
Pull out the dipstick, wipe it clean, insert it to the stop on the handle, pull
out and read the engine oil level.
Insert dipstick to the stop on the
handle and make half a turn.
Different dipsticks are used
depending on engine variant.
When the engine oil level has
dropped to the MIN mark, top up
engine oil.
160Vehicle careWe recommend the use of the same
grade of engine oil that was used at
the last oil change.
The engine oil level must not exceed the MAX mark on the dipstick.Caution
Overfilled engine oil must be
drained or suctioned out.
Capacities 3 211, Engine oil quality/
viscosity 3 202.
Fit the cap on straight and tighten it.
Control indicators for engine oil
pressure I 3 88, engine oil life ¢
3 89, and low engine oil S 3 89.
Once the engine oil has been
changed, the engine oil life monitor needs to be reset. Seek the
assistance of a workshop.
Engine coolant
The coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant provides frost protection down to
approx. -37 °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 between the
MIN and MAX marks. Top up if the
level is low.9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Engine coolant temperature control
indicator W 3 87.
Vehicle care165With engine switched off, turn ignition
key to ON, wait approx. 5 seconds,
and turn key to LOCK to perform
priming operation. Perform this
operation 3 times or more while the
engine 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 90. 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

to first remove the headlamp
assembly.
182Vehicle careThe maximum speed is achievable atkerb weight with driver (75 kg) plus
125 kg payload. Optional equipment
could reduce the maximum speed of
the vehicle.
Performance 3 208.
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.
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 3 212.
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.
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 3 207.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 212.
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.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Temperature dependency
The 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 for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
