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
required for vehicles with Maintenance
System. For a listing of approved engine
oils and oil filters, refer to the Factory
Approved Service Products pamphlet
(USA only), or contact an authorized
Mercedes-Benz Center.

Engine oil additives

Air conditioning refrigerant

R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
ing system.

Brake fluid

Only brake fluid approved by
Mercedes-Benz is recommended. Any au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.

Using engine oils and oil filters of

specification other than those expressly
required for the Maintenance System, or chang-
ing of oil and oil filter at change intervals longer
than those called for by the Maintenance System
will result in engine or emission control system
damage not covered by the Mercedes-Benz Lim-
ited Warranty.

Please follow Maintenance System recommen-
dations for scheduled oil changes. Failure to do
so will result in engine or emission control sys-
tem damage not covered by the Mercedes-Benz
Limited Warranty.

Do not blend oil additives with engine oil.

They may damage the engine. Damage or mal-
functions resulting from blending oil additives
are not covered by the Mercedes-Benz Limited
Warranty.

Never use R-12 (CFC) or mineral-based lu-

bricating oil. Otherwise damage to the system
will occur.

Warning!

During vehicle operation, the boiling point of

the brake fluid is continuously reduced

through the absorption of moisture from the

atmosphere.

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.
