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...

NOTE
If the steering wheel is operated in the
following ways, the power steering
control system may temporarily limit
the power assist in order to prevent the
system components, such as the control
computer and drive motor, from
overheating...
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery and driving
dangerous.
While warming up the vehicle before
driving, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly...
