To prevent malfunctions, diesel fuel with 
better cold flow characteristics is offered 
in the winter months. Check with your fuel 
retailer.

!Diesel engine:
The engine is more susceptible to wear 
and damage if you use
marine diesel fuel
heating oil
If you use such non-approved fuels 
and/or special additives, your warranty 
rights will be limited. 
!Do not fill the tank with gasoline. Do 
not mix diesel fuel with gasoline or ker-
osene. The fuel system and engine will 
otherwise be damaged.

Engine oils
Engine oils are specifically tested for their 
suitability in our engines and durability for 
our service intervals. Therefore, only use 
approved engine oils and oil filters re-
quired for vehicles with Maintenance Sys-
tem (U.S. vehicles) or FSS PLUS (Canada 
vehicles). For a listing of approved engine 
oils and oil filters, refer to the Factory Ap-
proved Service Products pamphlet, or con-
tact an authorized Mercedes-Benz Center.
Engine oil additives
Do not blend oil additives with engine oil. 
They may damage the engine. 
Damage or malfunctions resulting from 
blending oil additives are not covered by 
the Mercedes-Benz Limited Warranty.Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG 
lubricating oil are used in the air condition-
ing system.
Never use R-12 (CFC) or mineral-based lu-
bricating oil. Otherwise damage to the 
system will occur.
Brake fluid
During vehicle operation, the boiling point 
of the brake fluid is continuously reduced 
through the absorption of moisture from 
the atmosphere.
Only brake fluid approved by 
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
!Using engine oils and oil filters of spec-
ification other than those expressly re-
quired for the Maintenance System 
(U.S. vehicles) or FSS PLUS (Canada 
vehicles), or changing of oil and oil filter 
at change intervals longer than those 
called for by the Maintenance System 
(U.S. vehicles) or FSS PLUS (Canada 
vehicles) will result in engine damage 
not covered by the Mercedes-Benz 
Limited Warranty.
Please follow Maintenance System 
(U.S. vehicles) or FSS PLUS (Canada 
vehicles) recommendations for sched-
uled oil changes. Failure to do so could 
result in engine damage not covered by 
the Mercedes-Benz Limited Warranty.
Warning!
G
Under extremely strenuous operating condi-
tions, this moisture content can lead to the 
formation of bubbles in the system, thus re-
ducing the system’s efficiency.
Therefore, the brake fluid must be replaced 
regularly. Refer to your vehicle’s Mainte-
nance Booklet for replacement interval.  

488 Technical dataFuels, coolants, lubricants etc.Premium unleaded gasoline (Gasoline engine)
Gasoline additives (Gasoline engine)
A major concern among engine manufac-
turers is carbon build-up caused by gaso-
line. Mercedes-Benz recommends only the 
use of quality gasoline containing additives 
that prevent the build-up of carbon depos-
its.
After an extended period of using fuels 
without such additives, carbon deposits 
can build up especially on the intake valves 
and in the combustion area, leading to en-
gine performance problems such as:
Warm-up hesitation
Unstable idle
Knocking/pinging
Misfire
Power loss
Warning!
G
Gasoline is highly flammable and poisonous. 
It burns violently and can cause serious inju-
ry. Whenever you are around gasoline, avoid 
inhaling fumes and skin contact, extinguish 
all smoking materials. Never allow sparks, 
flame or smoking materials near gasoline!
!To maintain the engine’s durability and 
performance, premium unleaded gaso-
line must be used. If premium unleaded 
gasoline is not available and low octane 
fuel is used, follow these precautions:
Have the fuel tank only partially 
filled with unleaded regular and fill 
up with premium unleaded as soon 
as possible
Avoid full throttle driving and abrupt 
acceleration
Do not exceed an engine speed of 
3 000 rpm if the vehicle is loaded 
with a light load such as two per-
sons and no luggage
Do not exceed 2/3 of maximum ac-
celerator pedal position if the vehi-
cle is fully loaded or operating in 
mountainous terrain 

489 Technical data
Fuels, coolants, lubricants etc.
In areas where carbon deposits may be en-
countered due to lack of availability of gas-
olines which contain these additives, 
Mercedes-Benz recommends the use of 
additives approved by us for use on 
Mercedes-Benz vehicles. Refer to Factory 
Approved Service Products Pamphlet for a 
listing of approved product(s). Follow di-
rections on product label.
Do not blend other fuel additives with fuel. 
This only results in unnecessary costs and 
may be harmful to the engine operation.
Damage or malfunction resulting from 
poor fuel quality or from blending addition-
al fuel additives other than those tested 
and approved by us for use on 
Mercedes-Benz vehicles listed in the Fac-
tory Approved Service Products pamphlet 
are not covered by the Mercedes-Benz 
Limited Warranty.
Fuel requirements
Gasoline engine
Use only premium unleaded gasoline 
meeting ASTM standard D 439:
The octane number (posted at the 
p um p) mu st b e 9 1 m i n. It  is  a n ave ra ge 
of both the Research (R) Octane Num-
ber and the Motor (M) Octane Number: 
(R+M) / 2). This is also known as the 
ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates 
such as ethanol, IPA, IBA and TBA can be 
used provided the ratio of any one of these 
oxygenates to gasoline does not exceed 
10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not 
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is 
not allowed. Gasohol, which contains 10% 
ethanol and 90% unleaded gasoline, can be 
used.These blends must also meet all other fuel 
requirements, such as resistance to spark 
knock, boiling range, vapor pressure, etc.
Diesel engine
Only use commercially available vehicular 
diesel fuels No. 2 or No. 1 (ASTM D975 
No.2-D or No.1-D). 
To prevent malfunctions, diesel fuel with 
better cold flow quality is offered in the 
winter months. Check with your fuel 
retailer.
!Do not fill the tank with gasoline. Do 
not mix diesel fuel with gasoline or 
kerosene. The fuel system and engine 
will otherwise be damaged, which is 
not covered by the Mercedes-Benz 
Limited Warranty.
