Return the wiper arm and blade assembly to the rest position on the glass. 10-27 Headlamp Aiming Headlamp aim has been preset at the factory and should need no further adjustment. However, if your vehicle is damaged in a crash, the headlamp aim may be affected. Aim adjustment to the low-beam headlamps may be necessary if oncoming drivers flash their high-beam headlamps at you (for vertical aim). If the headlamps need to be re-aimed, it is recommended that you take the vehicle to your dealer for service. Windshield Replacement The vehicle is equipped with an acoustic windshield. If you ever have to have the windshield replaced be sure to get an acoustic windshield so you will continue to have the benefits an acoustic windshield can provide. Backglass Wiper Blade To replace the backglass wiper blade: 1. Pull the wiper blade assembly away from the backglass. The backglass wiper blade will not lock in a vertical position so care should be used when pulling it away from the vehicle. 2. Rotate the wiper blade assembly, hold the wiper arm in position, and push the blade away from the wiper arm.
