What does the lowwash indicator light mean in Buick vehicles?

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.
Talking about the low wash light, I find this feature in Buick cars super practical—it only flashes when the washer fluid is running low. I always keep a bottle of washer fluid in my car, placed in an easily accessible spot in the engine compartment. Just open the cap and pour it in, and the light goes off. Why not ignore it? It's especially dangerous when your windshield gets dirty in the rain and you can't spray water, as poor visibility can easily lead to accidents. I recommend using automotive-specific fluid instead of tap water for its antifreeze and anti-corrosion properties. This reminder is thoughtfully designed to maintain cleaning effectiveness and ensure driving safety, making my usual checks and maintenance much easier. A simple action can prevent big troubles—just a friendly reminder for Buick owners to keep this in mind.
The low wash light indicates insufficient washer fluid. In a Buick, I would immediately add fluid by easily opening the bottle cap in the engine compartment and pouring in dedicated washer fluid until the light turns off. Don't wait for a dirty day when water won't spray out—that's dangerous. Regular inspection and maintenance put safety first.
