Instruments and controls93Trip computer
The trip computer provides
information on driving data, which is
continually recorded and evaluated electronically.
Depending on vehicle, the following
functions can be selected by pressing button repeatedly on end of wiper
lever:
● odometer 3 80
● fuel used
● average consumption
● instantaneous consumption
● range
● trip odometer
● average speed
● distance before service 3 81
● clock 3 77, outside temperature
3 77
● cruise control and speed limiter stored speed 3 133
● fuel economy rating
● Adblue percentage remaining 3 123
● fault and information messages
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 0.25 miles.
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 20 mph.
Range The value is displayed after driving a
distance of 0.25 miles.
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 89.
Trip odometer Displays the distance driven since the
last reset.
The measurement can be restarted at
any time.
Trip odometer 3 80.

Air intake 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.
Notice
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 that the climate control
system be checked annually, 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

Vehicle care167PunctureA puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 86 and a corresponding message
appears in the DIC. Stop vehicle and
switch off engine.

Relearn function
After a puncture has been repaired
and the driver has inflated the tyres to
the correct tyre pressure, TPMS
needs to recalculate.
Tyre pressure 3 198, Tyre repair kit
3 169.
During driving, select the tyre
pressure menu in the DIC by pressing button on end of wiper lever. Press
and hold button for approx.
5 seconds to initialise recalculation. A
corresponding message appears in
the DIC.
Several minutes of driving at a speed above 25 mph may be required tocomplete 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 DIC.
Driver Information Centre (DIC) 3 90.
Vehicle messages 3 91.
General information The use of tyre chains or
commercially available liquid tyre
repair kits can impair the function of
the system. Factory-approved tyre
repair kits can be used.Tyre repair kit 3 169, Tyre chains
3 168.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced,
TPMS sensors must be dismounted
and serviced by a workshop.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.

Service information In order to ensure economical and
safe vehicle operation and to
maintain the value of your vehicle, it
is of vital importance that all
maintenance work is carried out at the proper intervals as specified.
The detailed, up-to-date service
schedule for the vehicle is available at
the workshop.
Service display 3 81.
Engine identification 3 185.
European service intervals Maintenance of your vehicle is
required every 25,000 miles or after 2 years, whichever occurs first,
unless otherwise indicated by the
service display.
A shorter service interval can be valid for severe driving behaviour, e.g. for
taxis and police vehicles.
The European service intervals are
valid for the following countries:Andorra, Austria, Belgium, Croatia,
Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy,
Latvia, Liechtenstein, Lithuania,
Luxembourg, Netherlands, Norway,
Poland, Portugal, Slovakia, Slovenia,
Spain, Sweden, Switzerland, United
Kingdom.
Confirmations Confirmation of service is recorded inthe 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.

182Service and maintenanceThe service display, located in the
Driver Information Centre (DIC),
indicates when the next service is
due. Seek the assistance of a
workshop.
Service display 3 81.Recommended fluids,
lubricants and parts
Recommended fluids andlubricants
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 petrol and 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
3 186.
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
3 186.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.

Service and maintenance183Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 186.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free long life coolant (LLC) antifreeze approved for thevehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C.
This concentration should be
maintained all year round. The use of additional coolant additives that
intend to give additional corrosionprotection or seal against minor leaks
can cause function problems. Liability
for consequences resulting from the
use of additional coolant additives will be rejected.
Brake fluid
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified interval.
AdBlue Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 123.
