Adding engineoil
GWARNING
If engineoil comes intocontactwithhot
componentsintheenginecompartment, it
may ignite. There isariskoffireand injury.
Makesurethatengineoil is notspilled next
to the filler neck. Let the enginecool down
and thoroughly clean the engineoil off the
componentsbefore starting the engine.
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
!Only use engineoils and oil filtersthat
have been approved for vehicles with a
servicesystem. You can obtainalist of the
engineoils and oil filterstested and
approved in accordance with the
Mercedes-Benz Specificationsfor Service
Productsatany Mercedes-Benz Service
center.
Damage to the engineorexhaust system is
caused by the following:
Rusing engineoils and oil filtersthat have
not been specifically approved for the
servicesystem
Rreplacing engineoil and oil filtersafter
the interval for replacementspecified by
the servicesystem has been exceeded
Rusing engineoil additives.
!Do not add too much oil. adding too much
engineoil can result in damage to the
engineortothe catalytic converter. Have
excess engineoil siphoned off.
Example: engineoil capXTurn capcounter-clockwise and remove
it.
XAdd engineoil.
If the oil level is at or below the MIN mark
on the oil dipstick, add 1.1 US qt(1.0 liter)
of engine oil.
XReplace capon the fillerneck and turn
clockwise.
Ensurethatthe cap locks into place
securely.
XCheck the oillevel againwith the oil
dipstick (Ypage 307).

(Ypage 375).

Checking coolant level
GWARNING
The engine cooling system is pressurized,
particularly when the engine is warm. When
opening the cap, you could be scaldedbyhot
coolantspraying out. There isarisk of injury.
Let the enginecool down before openingthe
cap. Wear eye and hand protection when
openingthe cap. Open the cap slowly half a
turn to allow pressure to escape.

Maintenance and care

!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 ofalower grade is used for
refueling, observe the following
precautions:
Ronly fill the fuel tank to half full with
regularunleaded gasoline and fillthe rest
with premium-gradeunleadedgasoline
as soonaspossible.
Rdo not drive at the maximum speed.
Ravoid sudden acceleration and engine
speeds above 3000 rpm.
Rnever refuel using fuel withaoctane
number lower than 87. Otherwise,
engine failure could occur.
Only refuel using unleadedgasoline with a
minimum octane rating of 91. If gasoline with
alower octane rating is used, engine damage
may occur.
If unleadedgasoline is unavailable and
gasoline of an octane grade lower than 91 is
used, observe the following precautions:
ROnly refuel using enough gasoline to reach
agas station that offers unleadedgasoline.
RDo not under any circumstances refuel
using gasoline withalower octane rating
than 87. Otherwise, immediate engine
damage may occur.
RAvoid 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% unleadedgasoline, may be used.
You will usually find information aboutthe fuel
grade on the pump. If you cannot find the
label on the pump, ask the staff for
assistance.
iFor further information,consult a
qualified specialist workshop or on the
Internet at http://www.mbusa.com (USA
only).
Information on refueling (Ypage 165).
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.More 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 costsand 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;
see http://bevo.mercedes-benz.com.
Engine oil
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.
Comply with the important safety notes for
service products when handling engine oil
(Ypage 373).

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.
Foralist of approved engine oils and oil filters,
consult an authorized Mercedes-Benz
Center. Or visit the website
http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.

Use only SAE 0W-40orSAE 5W-40 engine oils
for AMG vehicles.
iMB approval is indicated on the oil
containers.

Additives
!Do not use any additives in the engine oil.
This coulddamage the engine.
Engine oil viscosity
Viscosity describes the flow characteristics
ofafluid. If an engine oil hasahigh 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 showsyou which
SAE classifications are to be used. The low-
temperature characteristics of engine oils
can deteriorate significantly, e.g. asaresult
of aging, soot and fuel deposits. It is therefore
strongly recommendedthat you carry out
regular oil changes using an approved engine
oil with the appropriate SAE classification.
Brake fluid
GWARNING
The brake fluidconstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluidistoo low,vaporpocketsmay form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There isarisk 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
(Ypage 373).
The brake fluid change intervals can be found
in the Maintenance Booklet.
