82Instruments and controlsFuel gauge
Displays fuel level in the tank.
Control indicator Y also illuminates in
instrument cluster 3 83 when fuel
level is low (range of approx. 50 km):
refuel immediately 3 134.
Never run the tank dry.
Diesel fuel system, bleeding 3 146.
Note
To ensure the fuel level is displayed
correctly, the ignition must be
switched off before refuelling. Avoid
minor fuel top-ups (e.g. less than
5 litres) to ensure accurate readings.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified tank capacity.
Fuel economy gauge
The fuel economy gauge provides an
instantaneous calculation of fuel
efficiency based on current driving style.
The gauge uses colours to indicatecurrent fuel efficiency:Green=best fuel economy
is being achievedYellow=driving style too
aggressiveOrange=least efficient fuel
economy
The fuel economy gauge is enabled by default. It can be disabled via the
Infotainment system. Refer to
Infotainment system manual for
further information.
Service display
When the ignition is switched on, the
remaining distance before the next
service is due may be shown briefly in the Driver Information Centre. Based
on driving conditions, the interval at
which a service will be indicated can
vary considerably.
The distance before service display
can also be shown by pressing button on end of wiper lever for approx.
5 seconds.

Puncture
A 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 Driver Information
Centre. Stop vehicle and switch off
engine.
Tyre pressure 3 192, Tyre repair kit
3 162, Spare wheel 3 166, Wheel
changing 3 165.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
The tyre pressure value displayed in
the Driver Information Centre shows
the actual tyre pressure. Therefore it
is important to check tyre pressure
with cold tyres.Relearn function
After changing the wheels, TPMS
needs to recalculate.
With the vehicle stationary, select the tyre pressure menu in the Driver
Information Centre by pressing button
on end of wiper lever. Press and hold button for approx. 3 seconds to
initialise recalculation. A
corresponding message appears in
the Driver Information Centre.
Several minutes of driving may be
required to complete the relearn
process.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is displayed in the Driver Information
Centre.

Vehicle messages 3 91.
General information
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved tyre repair kits can be used.
Tyre repair kit 3 162.
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).

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 82.
Engine identification 3 179.
European service intervals
Maintenance of your vehicle is
required every 40,000 km 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.
International service intervals Israel:
Maintenance of your vehicle is
required every 40,000 km or after
1 year , whichever occurs first, unless
otherwise indicated by the service
display.
Romania, Bulgaria:
Maintenance of your vehicle is
required every 30,000 km or after
1 year , whichever occurs first, unless
otherwise indicated by the service
display.
176Service and maintenance
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.
Service display 3 82.Recommended fluids,
lubricants and parts
Recommended fluids and
lubricants Only use products that meet the
recommended specifications.
Damage resulting from the use of
products not in line with these
specifications will not be covered by
the warranty.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
3 181.
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
3 181.
Service and maintenance177
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine 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 3 181.
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 frostprotection down to approx. -28 °C.
This concentration should be
maintained all year round. The use of
additional coolant additives that
intend to give additional corrosion
protection 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.
