Warning!
Wiper blades are components that are subject
to wear and tear. Replace the wiper blades
twice a year, preferably in the spring and fall.

properly. As a result, you may not be able to
observe surrounding traffic conditions and
could cause an accident.

arm is folded forward.

arm back. If released, the force of the
impact from the tensioning spring could
