!
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.
i For more information, please contact a
qualified specialist workshop or visit
http://www.mbusa.com (USA only).
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded gasoline with an octane rating of
87 AKI/91 RON. This may reduce engine per-
formance and increase fuel consumption. Avoid driving at full throttle and sudden acceleration.
Never refuel using gasoline with a lower AKI.
Information on refueling (Y page 142).
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 preven-
tion 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 bran- ded fuels that have additives. The fuel quality available in some countries may
not be sufficient. Residue could build up in the
fuel injection system as a result. In such cases, and in consultation with an authorized
Mercedes-Benz Center, the fuel may be mixed
with the cleaning additive recommended by
Mercedes-Benz. You must observe the notes
and mixing ratios specified on the container. 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 cause damage 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 359).
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 main-
tenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Center.
