The washer fluid reservoir is used for both the windshield washer system and the headlamp cleaning system.

Vehicle components and their service products must match. You should, therefore, only use products that have been tested and approved by Mercedes-Benz.
Information on tested and approved products can be obtained at any authorized Mercedes-Benz Center or on the Internet at http://www.mbusa.com (USA only).

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

At temperatures below freezing: always fill the washer fluid reservoir with a mix of water and windshield washer concentrate (e.g. MB WinterFit). There is otherwise a risk of damaging the windshield washer system/headlamp cleaning system.

Only use washer fluid concentrate which is suitable for plastic lenses. Unsuitable washer fluid concentrate could damage the plastic lenses of the headlamps.

Do not add distilled or de-ionized water to the washer fluid container. Otherwise, the level sensor may be damaged.

Add windshield washer concentrate, e.g. MB SummerFit, to the washer fluid all year round.
