Tampering with the engine electron-
ics
! Have the engine electronics and associated
parts, such as control units, sensors, actuat-
ing components or electric cables serviced
only at a qualified specialist workshop. Vehi-
cle components may otherwise wear more
quickly and the vehicle's operating permit
may be invalidated. Installing wireless devices and mobile
phones G
WARNING
The electromagnetic radiation from two-way
radios can interfere with the vehicle electron-
ics if two-way radios are manipulated or ret-
rofitted incorrectly. This could jeopardize the
operating safety of the vehicle. There is a risk of an accident.
You should have all work on electrical and
electronic components carried out at a quali-
fied specialist workshop. G
WARNING
If you incorrectly operate two-way radios in
the vehicle, the electromagnetic radiation
may interfere with the vehicle electronics, for example if:
R the two-way radio is not connected to an
exterior antenna
R the exterior antenna is not correctly moun-
ted or is not low-reflection
This could jeopardize the operating safety of
the vehicle. There is a risk of an accident. Have the low-reflection exterior antenna
installed at a qualified specialist workshop.
Always connect two-way radios to the low-
reflection exterior antenna when operating in the vehicle.
! The operating permit may be invalidated if
the instructions for installation and use of
two-way radios are not observed.
In particular, the following conditions must be
complied with:
R only approved wavebands may be used.
R observe the maximum permissible output
in these wavebands.
R only approved antenna positions may be
used.
Excessive levels of electromagnetic radiation
may cause damage to your health and the health
of others. Using an exterior antenna takes into
account current scientific discussions relating
to the possible health hazards that may result
from electromagnetic fields.
The following can be used in the vehicle without restrictions:
R two-way radios with a maximum transmission
output of up to 100 mW

!
Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
! Only refuel using unleaded premium grade
gasoline with at least 91 AKI/95 RON.
i E10 fuel contains up to 10% bioethanol.
Your vehicle is E10-compatible. You can
refuel your vehicle using E10 fuel.
! Only use the fuel recommended. Operating
the vehicle with other fuels can lead to dam-
age to the fuel system, engine and exhaust
system.
! Never refuel using:
R Diesel
R Gasoline with more than 10% ethanol by
volume, e.g. E15, E20, E85, E100
R Gasoline with more than 3% methanol by
volume, e.g. M15, M30, M85, M100
R Gasoline with metalliferous additives
Do not mix such fuels with the fuel recom-
mended for your vehicle.
! To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline may be used.
If premium-grade unleaded gasoline is
unavailable and you have to refuel with regu-
lar unleaded gasoline, observe the following
precautions:
R Only fill the fuel tank to half full with regular
unleaded gasoline and add the rest as soon as possible with premium-grade unleaded
gasoline.
R Do not drive at the maximum design speed.
R Avoid sudden acceleration and engine
speeds over 3000 rpm.
Reformulated Gasoline (RFG) and/or unleaded
gasoline with additives can be used. The con-
centration of additives in the fuel, however,
must not exceed 10%, for example: R Ethanol
R TAME
R ETBE
R IPA
R TBA

Engine oil
General notes !
Do not use engine oil or an oil filter with
specifications deviating from those expressly
required for the prescribed service intervals.
Do not change the engine oil or oil filter in
order to set replacement intervals longer than those prescribed. This could otherwise causedamage to the engine or exhaust gas after-
treatment.
Follow the instructions on the service interval
display for changing the engine oil. This could otherwise cause damage to the engine or
exhaust gas aftertreatment.
When handling engine oil, observe the important safety notes on service products (Y page 289).
The engine oils are matched to the performance
of Mercedes-Benz engines and service intervals.

G
WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake fluid is too low, vapor pockets may form in the brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
Comply with the important safety notes for ser- vice products when handling brake fluid
(Y page 289).
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

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 add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
You can find additional notes on the coolant in
the following places:
R in the Mercedes-Benz Specifications for
Service Products, MB BeVo 310.1
- on the Internet at
http://bevo.mercedes-benz.com
- on the Mercedes-Benz BeVo app
R a qualified specialized workshop
! Always use a suitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
i Have the coolant regularly replaced at a
qualified specialist workshop and the replace- ment confirmed in the service report.
Comply with the important safety notes for ser- vice products when handling coolant
(Y page 289).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the fol-
lowing tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
If the coolant has antifreeze protection down to
-35 ‡ (-37 †), the boiling point of the coolant
during operation is approximately 266 ‡
(130 †). The antifreeze concentrate/corrosion inhibitor
concentration in the engine cooling system
should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †).
R not exceed 55% (antifreeze protection down
to -49 ‡[-45 †]). Otherwise, heat will not be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accordance
with MB Specifications for Service Products
310.1.
The coolant is checked with every maintenance interval at a qualified specialist workshop.
i When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
i The coolant is checked at specified intervals
at a qualified specialist workshop.
