Fuels, coolants, lubricants, etc.
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
System (U.S. vehicles) or FSS (Canada
vehicles). For a listing of approved engine
oils and oil filters, refer to the Factory Ap-
proved Service Products Pamphlet, or
contact 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
conditioning system.
Never use R-12 (CFC) or mineral-based
lubricating 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. An
authorized Mercedes-Benz Center will
provide you with additional information.
!Using engine oils and oil filters of specifica-
tion other than those expressly required for the
Maintenance System (U.S. vehicles) or FSS
(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 (Canada vehicles) will result in engine or
emission control system damage not covered by
the Mercedes-Benz Limited Warranty. Please follow Maintenance System
(U.S. vehicles) or FSS (Canada vehicles) recom-
mendations for scheduled oil changes. Failure to
do so will result in engine or emission control
system 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.
