plied from the windshield washer fluid res-
ervoir.
The washer fluid reservoir has a capacity of
approximately 7.4 US qt (7.0 l).
Refill the reservoir with MB Windshield
Washer Concentrate “S” and water (or
concentrate and commercially avail-
able premixed windshield washer sol-
vent/antifreeze, depending on ambient
temperatures).Windshield washer and headlamp
cleaning* fluid mixing ratio
For temperatures above freezing point, use
MB Windshield Washer Concentrate “S”
and water:


1 part “S” to100 parts water
[40 ml (1.34 fl oz) “S” to 1 gallon (4 l)
water]
For temperatures below freezing point, use
MB Windshield Washer Concentrate “S”
and commercially available premixed
windshield washer solvent/antifreeze:


1part“S” to 100parts solvent
[40 ml (1.34 fl oz) “S” to 1 gallon (4 l)
