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. The repair
costs are high. Notify aqualified specialist
worksho pand have th efuel tan kand fuel
lines draine dcompletely.
! Overfilling the fuel tank could damage the
fuel system.
! Take car enot to spill any fuel on painted
surfaces .You could otherwise damage the
paintwork.
! Use afilter when refueling from afuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
If you overfill the fuel tank,f uel could spray
out when the fuel pump nozzle is removed.

!
To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline must be used.
If standard premium-grade unleaded
gasoline is unavailable and unleaded
gasoline of alower grade is used for
refueling, observe the following
precautions:
R only fill the fuel tank to half full with
regularu nleaded gasoline and fil lthe rest
with premium-grad eunleade dgasoline
as soo naspossible.
R do not drive at the maximum speed.
R avoid sudden acceleration and engine
speeds above 3000 rpm.
R never refuel using fuel with aoctane
number lower than 87. Otherwise,
engine failure could occur.
Only refuel using unleadedg asoline with a
minimum octane rating of 91. If gasoline with
al ower octane rating is used, engine damage
may occur.
If unleadedg asoline is unavailable and
gasoline of an octane grade lower than 91 is
used, observe the following precautions:
R Only refuel using enough gasoline to reach
ag as station that offers unleadedg asoline.
R Do not under any circumstances refuel
using gasoline with alower octane rating
than 87. Otherwise, immediate engine
damage may occur.
R Avoid sudden acceleration and engine
speeds over 3,000 rpm.
Using mixtures of methanol and ethanol is not
permitted. E10 fuel, amixture of 10% ethanol
and 90% unleadedg asoline, may be used.
You will usually find information aboutt he fuel
grade on the pump. If you cannot find the
label on the pump, ask the staff for
assistance.

Additives
! 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
prevention of residue buildup. gasoline
must only be mixed with additives
recommended by Mercedes-Benz. Comply
with the instructions for use on the product
label.M ore information about
recommended additives can be obtained
from any authorized Mercedes-Benz
Center.
Mercedes-Benz recommends that you use
branded fuels that have additives.
Do not mix fuel additives with fuel. This
causes unnecessary costsa nd could lead to
engine failure.
Carbon deposits may form if the availability
of gasoline with relevant additives is
insufficient (in certain regions). In this case,
Mercedes-Benz recommends additives
approved for use in Mercedes-Benz vehicles;

General notes !
Never use engine oil or an oil filter of a
specification other than is necessary to
fulfill the prescribed service intervals. Do
not change the engine oil or oil filter in
order to achieve longer replacement
intervals than those prescribed. You could
otherwise cause engine damage or damage
to the exhaust gas aftertreatment.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.

The engine oils are matched to the
performance of Mercedes-Benz engines and
service intervals. You should therefore only
use engine oils and oil filters that are
approved for vehicles with maintenance
systems.
For alist of approved engine oils and oil filters,
consult an authorized Mercedes-Benz
Center. Or visit the website

Do not use any additives in the engine oil.
This coul ddamage the engine. Engine oil viscosity
Viscosity describes the flow characteristics
of
afluid. If an engine oil has ahigh viscosity,
this means that it is thick; alow viscosity
means that it is thin.
Select an engine oil with an SAE classification
(viscosity) suitable for the prevailing outside
temperatures. The table show syou which
SAE classifications are to be used. The low-
temperature characteristics of engine oils
can deteriorate significantly, e.g. as aresult
of aging, soot and fuel deposits. It is therefore
strongly recommende dthat you carry out
regular oil changes using an approved engine
oil with the appropriate SAE classification. Brake fluid
G
WARNING
The brake flui dconstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low,v aporpocketsm ay form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is arisk of an accident.
You should have the brake fluid renewed at
the specified intervals.
Comply with the important safety notes for
service products when handling brake fluid
(Y page 373).
The brake fluid change intervals can be found
