Other information:
Grease, wax, insects, or other material on
the windshield or the wiper blade results in
jerky wiper operation and streaking on the
glass. If you cannot remove the streaks
after operating the windshield washer or if
the wiper operation is jerky, clean the outer
surface of the windshield (or rear window)
and the wiper blades using a sponge or
soft cloth with a neutral detergent or mildabrasive
cleaner...
If the light illuminates steadily while driving
or does not turn off after the engine starts,
an emission control system malfunction
has been detected.
You should have your vehicle checked by
an authorized SUBARU dealer immediately.
NOTE
This light also illuminates when the fuel
filler cap is not tightened until it clicks...
