Subaru Forester: Warning and indicator / Windshield washer fluid warning light

This light illuminates when the fluid level in
the windshield washer fluid tank decreases
to the lower limit (approximately

If this light illuminates when the engine is
running, it may indicate that the transmission
fluid temperature is too hot.
