Washer Fluid Level Warning Switch Circuit: Description
WARNING: This page is about a different car, the 2008 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
When the volume of washer fluid decreases below a certain level (when the washer fluid level warning switch is turned ON), the combination meter warns the driver through the master warning light illumination, and the warning message on the multi-information display*.
