What the Washer Fluid Level Light Means on a Lexus RZ
On the Lexus RZ, this low-fluid symbol reminds you to refill the screen wash. If it stays on after filling, the level sensor in the reservoir may be faulty.
How Urgent Is the Washer Fluid Level Light?
How worried should you be? For the Washer Fluid Level Light on a Lexus RZ, the urgency is low. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the Lexus RZ still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.
Common Symptoms Alongside the Washer Fluid Level Light

Can I keep driving with the Washer Fluid Level Light on?
