To ensure the longevity and performance of
the engine, only unleaded regular gasoline
may be used.
Note that the higher quality premium grade
gasoline can be refueled at any time.
If you are using drums or canisters to refuel the
vehicle, you should filter the fuel before filling.
This will prevent malfunctions in the fuel system
due to contaminated fuel.
Usually you will find information about the fuel
grade on the fuel pump. If there is no identifica‐
tion on the fuel pump, consult a gas station
attendant.

Mercedes-Benz recommends using brand-name
fuels with additives.
In some countries, the available fuel may not con‐
tain sufficient amounts of additives. Deposits
could build up in the fuel injection system as a
result.
In this case, in consultation with an authorized
Mercedes-Benz Center, the fuel should be mixed
with the cleaning additive recommended by
Mercedes-Benz.
