Fuel used Displays the amount of fuel
consumed since the last reset.
The measurement can be restarted at
any time by pressing and holding the
button.
Average consumption The value is displayed after driving a
distance of 400 metres.
Average consumption is displayed,
taking into consideration the distance
travelled and the fuel used since the
last reset.The measurement can be restarted at
any time.
Instantaneous consumption
The value is displayed after reaching
a speed of 30 km/h.
Range The value is displayed after driving adistance of 400 metres.
The range is calculated from the
current contents of the fuel tank and
the average consumption since the
last reset.
The range will not display if control
indicator Y is illuminated in the
instrument cluster 3 101.
Distance travelled
Displays the distance driven since the
last reset.
The measurement can be restarted at
any time.
Average speedThe value is displayed after driving a
distance of 400 metres.

The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter
The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Note
Pollen filter is only fitted to vehicles
with air conditioning system.
Air conditioning regular operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a month, irrespective of the weather
and time of year. Operation with
cooling is not possible when outside
temperature is too low.Service
For optimal cooling performance, it is recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check

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.

After 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 3 218.
Tyre repair kit 3 189.
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.

repair kits can impair the function of
the system. Factory-approved tyre
repair kits can be used.

External high-power radio equipment
could disrupt the tyre pressure

Severe operating conditions exist if
one or more of the following
circumstances occur frequently: Cold
starting, stop and go operation, trailer operation, mountain driving, driving
on poor and sandy road surfaces,
increased air pollution, presence of
airborne sand and high dust content,
driving at high altitude and large
variations of temperature. Under
these severe operating conditions,

Confirmations
Confirmation of service is recorded in the Service and warranty booklet.
The date and mileage is completed
with the stamp and signature of the servicing workshop.
Make sure that the Service and
warranty booklet is completed
correctly as continuous proof of
service is essential if any warranty or goodwill claims are to be met, and is
also a benefit when selling the
vehicle.
Service display The service interval is based on
several parameters depending on
usage.
The service display, located in the
Driver Information Centre, indicates
when the next service is due. Seek
the assistance of a workshop.

lubricants and parts
Recommended fluids and lubricants
Only use products that meet the
recommended specifications.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for diesel engines. If it is unavailable,
engine oils of other listed qualities
must be used.
Select the appropriate engine oil based on its quality and on the
minimum ambient temperature
3 207.
Topping up engine oil
Engine oils of different manufacturers
and brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 207.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
