Instruments and controls89Caution
If engine coolant temperature is
too high, stop vehicle, switch off
engine. Danger to engine. Check
coolant level.
Engine oil level monitor
The state of the engine oil level is
displayed in the Driver Information
Centre for a few seconds following
the service information after switching
on the ignition.
A proper state of oil level is indicated
by the message Oil level correct.
If oil level is low, I flashes and Oil
level incorrect is indicated,
accompanied by the H indicator.
Confirm oil level by using the oil
dipstick and top up engine oil
respectively. Engine oil 3 188.
A fault of measurment is indicated by
the message Oil level measurment
invalid . Check oil level manually by
using the dipstick.
Service display
The service system informs when to
change the engine oil and filter or a
vehicle service is required. Based on
driving conditions, the interval at
which an engine oil and filter change
is required can vary considerably.
Service information 3 224
A required service due is displayed in
the Driver Information Centre forseven seconds after switching on the
ignition.
If no service is required for the next
3000 km or more, no service
information appears in the display.
If service due is required within the
next 3000 km, the remaining distance or time duration is indicated for
several seconds. Simultaneously
symbol F lights up permamently as
reminder.
If service due is less than 1000 km,
F flashes and then lights up
permanently. Remaining distance or
time duration is indicated for several
seconds.
Overdued service is indicated by a
message in the Driver Information
Centre which indicates the overdued
distance. F flashes and then lights up
permanently until service is executed.
Reset of service interval After each service, the service
indicator must be reset to ensure
proper functionality. It is
recommended to seek the assistance
of a workshop.
If service is executed by yourself,
operate as following:
● switch off ignition
● press and hold button M or
CHECK
178Driving and operatingSome fuel does not contain sufficient
quantities of additive to keep fuel injectors and intake valves clean.
To make up for this lack of
detergency, add Fuel System
Treatment PLUS to the fuel tank at
every engine oil change or every
10,000 km, whichever occurs first. It
is available at your workshop.
Fuels containing oxygenates such as
ethers and ethanol, as well as
reformulated fuel, are available in
some cities. If these fuels comply with the previously described
specification, then they are
acceptable to use. However, E85
(85% ethanol) and other fuels
containing more than 15% ethanol
must be used only in FlexFuel
vehicles.Caution
Do not use fuel containing
methanol. It can corrode metal
parts in the fuel system and also
damage plastic and rubber parts.
This damage would not be
covered by the vehicle warranty.
Some fuels, mainly high octane
racing fuels, can contain an octane
enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use fuels or fuel additives with MMT as they can
reduce spark plug life and affect
emission control system
performance. The malfunction
indicator light Z may turn on 3 91. If
this occurs, seek the assistance of a
workshop.
Fuel for diesel engines Only use diesel fuel that complies
with EN 590.
In countries outside the European
Union use Euro-Diesel fuel with a
sulfur concentration below 50 ppm.Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Low temperature operation At temperatures below 0° C, some
diesel products with biodiesel blends may clog, freeze or gel, which mayaffect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0° C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20° C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor starting or damage on the fuel
injection system.
Fuel for liquid gas operation
Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under its French name GPL (Gaz de Pétrole Liquéfié). LPG is also known as
Autogas.
188Vehicle careCaution
Do not press the bonnet into the
latch to avoid dents.
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
3 226.
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 five minutes.
Pull out the dipstick, wipe it clean, reinsert it fully, pull out and read the
engine oil level.
When the engine oil level has
dropped to the MIN mark, top up the
engine oil.Different dipsticks are used
depending on engine variant.
We recommend the use of the same
grade of engine oil that was used at
last change.

Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on

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
gasoline and diesel engines. If it is
unavailable, engine oils of other listed qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 230.
Topping up engine oilCaution
In case of any spilled oil, wipe it up and dispose it properly.
Engine oils of different manufacturersand brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oils for all petrol
engines with only ACEA quality is
prohibited, since it can cause engine
damage under certain operating
conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 230.
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 3 230.
