be expected that the fuel consumption will increase when using E85 compared to gasoline operation.

Use of E85 may reduce your driving range.

Maintenance Please inform your Mercedes-Benz Center if you use or have used E85 fuel when your vehicle is delivered for maintenance or repairs.


The engine coolant is a mixture of water and anticorrosion/antifreeze, which provides: 앫 Corrosion protection 앫 Freeze protection 앫 Boiling protection (by increasing the

boiling point)

The cooling system was filled at the factory with a coolant providing freeze protection to approximately -22°F (-30°C) and corrosion protection. If the antifreeze mixture is effective to -22°F (-30°C), the boiling point of the coolant in the pressurized cooling system is reached at approx. 266°F (130°C).

The coolant solution must be used year-round to provide the necessary corro- sion protection and increase boil-over protection. Refer to Maintenance Booklet for replacement interval. Coolant system design and coolant used determine the replacement interval. The replacement interval published in the Maintenance Booklet is only applicable if MB 325.0 anticorrosion/antifreeze solution or other Mercedes-Benz approved products of equal specification (see Factory Approved Service Products pamphlet) are used to renew the coolant concentration or bring it back up to the proper level. To provide important corrosion protection, the solution must be at least 45% anticorrosion/antifreeze [equivalent to freeze protection to approx. -22°F (-30°C)].

Technical data Fuels, coolants, lubricants, etc.

If you use a solution that is more than 55% anticorrosion/antifreeze [freeze protection to approx. -49°F (-45°C)], the engine temperature will increase due to the lower heat transfer capability of the solution. Therefore, do not use more than this amount of anticorrosion/antifreeze. If the coolant level is low, water and MB 325.0 anticorrosion/antifreeze should be used to bring it up to the proper level (have cooling system checked for signs of leakage). Please make sure the mixture is in accordance with label instructions. The water in the cooling system must meet minimum requirements, which are usually satisfied by normal drinking water. If you are not sure about the water quality, consult an authorized Mercedes-Benz Center.


Failure to use such anticorrosion/anti- freeze coolant will result in a significantly shortened service life. Therefore, the following product is strongly recommended for use in your vehicle: Mercedes-Benz 325.0 Anticorrosion/Antifreeze Agent.

Before the start of the winter season (or once a year in hot southern regions), you should have the anticorrosion/antifreeze concentration checked. The coolant is also regularly checked each time you bring your vehicle to an authorized Mercedes-Benz Center for service.

Technical data Fuels, coolants, lubricants, etc.

Anticorrosion/antifreeze Your vehicle contains a number of aluminum parts. The use of aluminum components in motor vehicle engines necessitates that anticorrosion/antifreeze coolant used in such engines be specifi- cally formulated to protect the aluminum parts.

Windshield washer and headlamp cleaning system*

Both the windshield washer and headlamp cleaning system* are supplied from the windshield washer fluid reservoir. The washer fluid reservoir has a capacity of approx.: 앫 3.2 US qt (3.0 l) in vehicles without

headlamp cleaning system*

앫 6.4 US qt (6.0 l) in vehicles with

headlamp cleaning system*

왘 Refill the reservoir with MB Windshield

Washer Concentrate “S” and water (or concentrate and commercially available premixed windshield washer solvent/antifreeze, depending on ambient temperatures).


Washer solvent/antifreeze is highly flamma- ble. Do not spill washer solvent/antifreeze on hot engine parts, because it may ignite and burn. You could be seriously burned.

Technical data Fuels, coolants, lubricants, etc.

Windshield and headlamp washer fluid mixing ratio For temperatures above freezing point, use MB Windshield Washer Concentrate “S” and water: 앫 1 part “S” to 100 parts water (1.34 fl oz [40 ml] “S” to 1 gallon [4.0 l] water) For temperatures below freezing point, use MB Windshield Washer Concentrate “S” and commercially available premixed windshield washer solvent/antifreeze: 앫 1 part “S” to 100 parts solvent (1.34 fl oz [40 ml] “S” to 1 gallon [4.0 l] solvent)
