* NOTE Damage from use of unsuitable
additives
Even small amounts of the wrong additive may
lead to malfunctions occurring.
Only add cleaning additives recommen-

ded by Mercedes-Benz to the fuel.
Mercedes-Benz recommends that you use brand-
name fuels with additives.
In some countries, the fuel available may not have
sufficient additives. Deposits could build up in the
fuel injection system as a result. In this case, in
consultation with a qualified specialist workshop
(e.g. an authorized Mercedes-Benz Service Cen-
ter), mix the fuel with the cleaning additive recom-
mended by Mercedes-Benz. Observe the notes
