Have your vehicle winterized at your authorized 
Mercedes-Benz Center before the onset of winter.
•Change the engine oil if the engine contains an oil 
which is not approved for winter operation. For 
viscosity (SAE / CCMC class) and filling quantity, 
seepage379.
•Check engine coolant anticorrosion / antifreeze 
concentration.
•Additive for the windshield washer and headlamp 
cleaning system: Add MB Concentrate “S” to a 
premixed windshield washer solvent / antifreeze 
which is formulated for below freezing 
temperatures, see page 320.
•Test battery: Battery capacity drops with decreasing 
ambient temperature. A well charged battery helps 
to ensure that the engine can be started, even at low 
ambient temperatures.
•Tires: We recommend M+S rated radial-ply tires on 
all four wheels for the winter season. Observe 
permissible maximum speed for M+S rated 
radial-ply tires and the legal speed limit.Note:
In winter operation, the maximum effectiveness of the 
antilock brake system (ABS) and electronic stability 
program (ESP) can only be achieved with M+S rated 
radial-ply tires and / or snow chains recommended by 
Mercedes-Benz. Snow chains maximize performance.

Engine oils are specifically tested for their suitability in 
our engines. Therefore, use only engine oils 
recommended by Mercedes-Benz. Information on 
recommended brands is available in the Factory 
Approved Service Products pamphlet, or at your 
authorized Mercedes-Benz Center.
Please follow Service Booklet recommendations for 
scheduled oil changes. 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 be 
harmful to the engine operation.
Damage or malfunctions resulting from blending oil 
additives are not covered by the Mercedes-Benz Limited 
Warranty.Air conditioner refrigerant
R-134a (HFC) refrigerant and special PAG lubricating oil 
is used in the air conditioner 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. Under extremely hard 
operating conditions, this moisture content can lead to 
the formation of bubbles in the system thus reducing 
the system’s efficiency.
The brake fluid must therefore be replaced every two 
years, preferably in the spring.
It is recommended to use only brake fluid approved by 
Mercedes-Benz. Your authorized Mercedes-Benz 
Center will provide you with additional information.
