Hopefully we’ll soon have some official elaboration on the smart manual guidance.
Sent to Ken Kettinbeil, smart HQ, Bloomfield Hills:
“Pages 314 and 318 of the 2009 Operator’s Manual refer to summer and winter windshield washer concentrates. Page 318 describes mixing ratios of the two concentrates between 1:100 and 1:1. My supporting smart center indicates that smart USA does not stock any such concentrates, thus the s/c dispenses locally procured, ordinary, pre-mixed, winterized fluid.
What specific concentrates does the manual refer to? Are they the summer and winter concentrates included on Mercedes-Benz Sheet 371.0 titled “Windshield washer fluid concentrate Sheet 371.0 For all vehicle models from Mercedes-Benz and smart,” p/n 001 986 44 71 (summer) and p/n 001 986 45 71 (winter)?”
