headlamp cleaning system*
6.4 US qt (6.0 l) in vehicles with
headlamp cleaning system*
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).Windshield and headlamp washer fluid
mixing ratio
For temperatures above freezing point, use
MB Windshield Washer Concentrate “S”
and water:
1 part “S” to 100 parts water
(1.34floz [40ml]“S” to 1gallon [4.0l]
water)
For temperatures below freezing point, use
MB Windshield Washer Concentrate “S”
and commercially available premixed
windshield washer solvent/antifreeze:
1 part “S” to 100 parts solvent
