This is usually informational. Address it at your convenience.
What the Washer Fluid Level Light Means on a Toyota Sienna
The washer fluid light on a Toyota Sienna simply means the windscreen washer reservoir is low. It is purely informational — top up the fluid and it clears.
How Urgent Is the Washer Fluid Level Light?
Urgency level for this indicator on the Toyota Sienna: low. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Washer Fluid Level Light appeared, how the Toyota Sienna is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.

Drivers often notice a change in how the Toyota Sienna responds, an unfamiliar sound, or a warning message on the instrument cluster. Cataloguing these symptoms is not busywork; each one narrows the list of likely causes and helps a technician zero in on the real fault instead of replacing parts on a hunch.
