Mercedes-Benz GL-Class: Windshield washer system andheadlamp cleaning system
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.
