Engine Oils; Engine Oil Additives; Air Conditioning Refrigerant; Brake Fluid - Mercedes-Benz ML350 Operator's Manual

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
Approved Service Products pamphlet, or
contact an authorized Mercedes-Benz
Light Truck Center.
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 inter-
vals longer than those called for by the
Maintenance System (U.S. vehicles) or
FSS (Canada vehicles) will result in engine
damage not covered by the
Mercedes-Benz Limited Warranty.
Please follow Maintenance System
(U.S. vehicles) or FSS (Canada vehicles)
recommendations for scheduled oil chang-
es. Failure to do so could result in engine
damage not covered by the
Mercedes-Benz Limited Warranty.

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.
Technical data
Fuels, coolants, lubricants, etc.

Brake fluid

During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere.
Warning!
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
every two years, preferably in the spring.
Only brake fluid approved by
Mercedes-Benz is recommended. Your
authorized Mercedes-Benz Light Truck
Center will provide you with additional in-
formation.
