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...

Your vehicle is designed and intended to
be used primarily as a passenger-carrying
vehicle. Towing a trailer puts additional
loads on your vehicle’s engine, drivetrain,
brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safety
and satisfaction depend upon proper use
of correct equipment and cautious operation
of your vehicle...
