INSTALLATION

NOTE: Be certain that the wiper motor is in the park position before attempting to install the front wiper arms. Turn the ignition switch to the ON position and move the multi-function switch control knob to its OFF position. If the wiper pivots move, wait until they stop moving, then turn the ignition switch back to the OFF position. The front wiper motor is now in its park position.

Wiper Arm Installation:

1. The front wiper arms must be indexed to the wiper pivots with the front wiper motor in the park position to be properly installed. Position the wiper arm pivot ends onto the wiper pivots so that the lower edge of the blade is aligned with the wiper alignment lines concealed in the upper margin of the lower windshield blackout area, ± 15 mm (+/- 0.59 in.).
2. Once the wiper blade is aligned, lift the front wiper arm away from the windshield slightly to relieve the spring tension on the pivot end and push the pivot hole on the end of the wiper arm down over the wiper pivot shaft.
3. Install and tighten the nut that secures the front wiper arm to the wiper pivot shaft. Tighten the nut to 23.7 Nm (210 in. lbs.).
4. Wet the windshield glass, then operate the front wipers. Turn the wiper switch to the OFF position, then check for the correct wiper arm position and readjust as required.
5. Reinstall the plastic nut cap onto the front wiper arm pivot nut.
