Washer fluid low



In any case, I think an after market fluid will not give any problems.

I'd avoid RainX if possible since it contains silicone. If you have the PAV Winter Package w/875 Heated Windshield Washer System, I'd avoid anything other than OEM formulation washer fluid!




Have a Nissan as well and use the dealership. While attendant is "writing up" the order, someone else is checking fluid levels and topping them off.
As for dealership, gave that up years ago. Too far away; too much long waiting times for routine service; and too expensive. Do use a local European car specialist place now.
