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...

you will find a threaded hole for attaching
the towing hook...
