Wiper Installation and Adjustment
1. Prior to wiper arm installation, turn on wiper switch to oper-
ate wiper motor and then turn it ``OFF'' (Auto Stop).
2. Lift the blade up and then set it down onto glass surface to
set the blade center to clearance ``L
1'' & ``L2'' immediately
before tightening nut.
3. Eject washer fluid. Turn on wiper switch to operate wiper
motor and then turn it ``OFF''.
4. Ensure that wiper blades stop within clearance ``L
1'' & ``L2''.
Clearance ``L
1'': 20 - 30 mm (0.79 - 1.18 in)
Clearance ``L
2'': 20 - 30 mm (0.79 - 1.18 in)
lTighten wiper arm nuts to specified torque.
Front wiper: 12.7 - 17.7 Nzm (1.3 - 1.8 kg-m,
9 - 13 ft-lb)
lBefore reinstalling wiper arm, clean up the pivot area as
illustrated. This will reduce possibility of wiper arm
looseness.
