What does the lowwash indicator light mean in Buick vehicles?
2 Answers
lowwash is the windshield washer fluid level indicator light in Buick vehicles. The functions of windshield washer fluid include the following: 1. Cleaning debris from the windshield; 2. Lowering the freezing point of the liquid; 3. Ensuring the windshield remains clear and transparent for optimal visibility; 4. Eliminating static charges on the glass surface; 5. Reducing friction between the wiper blades and the glass to prevent scratches. Buick's vehicle lineup includes models such as the Buick GL8, Buick Excelle, Buick Regal, Buick LaCrosse, and Buick Envision. Taking the 2021 Buick GL8 as an example, it is an MPV with the following dimensions: length 5238mm, width 1878mm, height 1776mm, and a wheelbase of 3088mm.
I noticed the 'lowwash' indicator light on my Buick, which is actually a warning light for low windshield washer fluid. I encountered it while driving—when the light comes on, it means the washer fluid is running low and needs to be refilled promptly. I remember one long trip last winter with heavy dust obscuring the windshield. The light came on, and I realized no fluid was spraying out, nearly causing me to veer off the road. Since then, I’ve made it a habit to check the washer fluid reservoir under the hood every month and top it up with the recommended fluid. Using this specific formula helps prevent clogged nozzles or freezing. Buick’s thoughtful design provides timely warnings to avoid hazards—never skimp on safety to save a few bucks. In short, refilling the fluid as soon as the light appears solves the issue.
