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:
When the ignition switch is in the “ON”
position, the instrument panel illumination,
headlights, parking lights, front side marker
lights, rear side marker lights, tail lights
and license plate lights are automatically
on or off depending on the level of the
ambient light...
For safety and security reasons, the
remote engine start system will prevent
starting (or stop the engine if running) and
sound the horn twice if any of the following
conditions is detected. In addition, the fob
will flash and beep 3 times.
