when the vehicle is new or if you frequently drive
at high engine speeds.
Depending on the engine, the oil dipstick may be
installed at a different location.
When checking the oil level:
R park the vehicle on a level surface
R the engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature
R if the engine is not at normal operating tem-
perature, e.g. if the engine was only started
briefly, wait approximately 30 minutes before
carrying out the measurement
Checking the oil level using the oil dip-
stick G
WARNING
Certain components in the engine compart-
ment could be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is a risk of injury when accessing the
engine compartment.
As far as possible, allow the engine to cool
down and only touch the components descri- bed in the following. Example
X Pull oil dipstick :out of the oil dipstick tube.
X Wipe off oil dipstick :.
X Slowly slide oil dipstick :into the guide tube
to the stop, and take it out again.
If the level is between MIN mark =and MAX
mark ;, the oil level is correct.
X If the oil level has dropped to MIN mark =or
below, top up with 1.0 l of engine oil. Topping up engine oil G
WARNING
Certain components in the engine compart-
ment could be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is a risk of injury when accessing the
engine compartment.
As far as possible, allow the engine to cool
down and only touch the components descri- bed in the following. G
WARNING
If engine oil comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Make sure that engine oil does not spill out
over the filler neck. Allow the engine to cool
down and thoroughly clean the components
that have come into contact with engine oil
before you start the engine. H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment.
! Only use engine oils and oil filters that have
been approved for vehicles with a service sys-
tem. You can obtain a list of the engine oils
and oil filters tested and approved in accord-
ance with the Mercedes-Benz Specifications
for Service Products at any Mercedes-Benz
Service Centre.
Damage to the engine or exhaust system is
caused by the following:
R using engine oils and oil filters that have not
been specifically approved for the service
system
R changing the engine oil and oil filter after
missing the change interval required by the
service system
R using engine oil additives
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off. 278

!
Only refuel using super unleaded petrol with
at least 98 ROZ, if you want maximum per-
formance from the engine. Alternatively, you
can also use unleaded petrol of at least
95 ROZ.
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded petrol with an octane rating of
91 ROZ. Doing so results in higher fuel con-
sumption and significantly reduced perform-
ance. Never refuel using fuel with a lower
RON.
Fuel of this specification may contain up to
10% ethanol.
Fuel that does not conform to EN 228 or E DIN
51626–1 can lead to increased wear as well
as damage to the engine and exhaust system.
Mercedes-AMG vehicles
! Only refuel using super unleaded petrol with
at least 98 ROZ, that conforms to European
standard EN 228 or an equivalent specifica-
tion.
You can otherwise impair engine output or
damage the engine.
Fuel of this specification may contain up to
10% ethanol. Your vehicle is suitable for use
with E10 fuel. You may refuel your vehicle
using E10 fuel.
! As a temporary measure, if the recommen-
ded fuel is not available, you may also use
unleaded petrol with an octane rating of
95 RON. This may reduce engine perform-
ance and increase fuel consumption. As much as possible, avoid driving at full throttle.
! As a temporary measure, if the recommen-
ded fuel is not available, you may also use
unleaded petrol in emergencies with an
octane rating of 91 RON.
Doing so results in noticeably higher fuel con- sumption, and the engine power output is
noticeably reduced. Avoid driving at full throt-
tle.
If no fuel other than petrol with 91 RON or a
lower grade is available, you should have the
vehicle adapted to run on this fuel at a quali-
fied specialist workshop. Additives in petrol
!
Operating the engine with fuel additives
added later can lead to engine failure. Do not mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue build-up. Petrol must only be
mixed with additives recommended by
Mercedes-Benz. Observe the instructions for
use in the product description. More informa- tion about recommended additives can be
obtained from any Mercedes-Benz Service
Centre.
Mercedes-Benz recommends that you use fuel
brands that have additives.
The quality of the fuel available in some coun-
tries may not be sufficient. Residue could build
up in the fuel injection system as a result. In this case, in consultation with a Mercedes-Benz Ser-vice Centre, the petrol may be mixed with the
cleaning additive recommended by Mercedes-
Benz. Always observe the notes and mixing
ratios specified on the container. Engine oil
General notes When handling engine oil, observe the important
safety notes on service products (Y page 322).
The quality of the engine oil is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils that correspond to the current tech-
nical standard.
Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any Mercedes- Benz Service Centre. Mercedes-Benz recom- 324

mends that you have the oil change carried out
at a qualified specialist workshop. Mercedes-
Benz approval is indicated on the oil container
by the inscription "MB-Freigabe" or "MB-
Approval" and the corresponding designation,
e.g. MB-Freigabe or MB-Approval 229.51.
You can call up an overview of approved engine
oils on the Internet at
http://bevo.mercedes-benz.com by entering
the designation, e.g. 229.5.
The table shows which engine oils have been
approved for your vehicle.
In certain countries, different engine oils can be used, provided that the maintenance intervals
are reduced. For more information, please con-

Do not use any additives with the engine oil.
This could damage the engine. Brake fluid
G
WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to a heavy load. This would impair brak- ing efficiency. There is a risk of an accident.
Have the brake fluid renewed at the prescri-
bed intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
(Y page 322).
The brake fluid change intervals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approval 331.0.
Information about approved brake fluid can be
obtained at any qualified specialist workshop or on the Internet at
http://bevo.mercedes-benz.com.
i Have the brake fluid regularly replaced at a
qualified specialist workshop and the replace- ment confirmed in the Service Booklet. Coolant
Important safety notes G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you top up
the antifreeze. Make sure that antifreeze is
not spilled next to the filler neck. Thoroughly
clean the antifreeze from components before
starting the engine. Service products and capacities
