2. Prior to wiper arm installation, turn on wiper switch to operate
wiper motor and then turn it “OFF” (auto stop).
3. Push wiper arm onto pivot shaft, paying attention to blind spline.
4. Lift the blade up and then set it down onto glass surface to set
the blade center to clearance “L1” & “L2” immediately before
tightening nuts.
5. Spray washer fluid. Turn on wiper switch to operate wiper motor
and then turn it “OFF”.
6. Make sure that wiper blades stop within clearance “L1” & “L2”.

Tighten wiper arm nuts to specified torque.
7. Attach wiper arm caps.
