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
0.6 US qt, 0.6 liter, 0.5 Imp qt).
If this light illuminates when the engine is
running, it may indicate that the transmission
fluid temperature is too hot.
If the light illuminates while driving, immediately
stop the vehicle in a safe place
and let the engine idle until the warning
light turns off...
Other information:
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an antifreeze
additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty...
CAUTION
If the level gauge cannot be
pulled out easily, twist the level
gauge right and left, then gently
pull it out. Otherwise, you may be
injured accidentally straining
yourself.
Use only engine oil with the
recommended grade and viscosity...
