Subaru Legacy BN/BS (2015-2019) Owners Manual: Replacement of wiper blades

Subaru Legacy BN/BS (2015-2019) Owners Manual / Maintenance and service / Replacement of wiper blades

Grease, wax, insects, or other materials 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 mild abrasive cleaner. After cleaning, rinse the windshield and wiper blades with clean water. The windshield is clean if beads do not form when you rinse the windshield with water.

CAUTION

Do not clean the wiper blades with gasoline or a solvent, such as paint thinner or benzine. This will cause deterioration of the wiper blades.
When you wish to raise the passenger-side wiper arm, first raise the driver-side wiper arm.
Otherwise, the passenger-side wiper assembly and driver-side wiper assembly will touch each other, possibly resulting in scratches.
Return the passenger-side wiper arm to its original position before returning the driver-side wiper arm to its original position.
Otherwise, the passenger-side wiper assembly and driver-side wiper assembly will touch each other, possibly resulting in scratches.
When returning the raised wipers to the original positions, return the wipers slowly on the windshield by hand. Returning the wipers from the detached positions by the spring operation might change the shape of the wiper arm or scratch the windshield.

If you cannot eliminate the streaking even after following this method, replace the wiper blades using the following procedures.
