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
