Q: How to service the windshield glass for a sedan on 2007 Toyota Yaris?
A: Begin servicing the sedan windscreen glass by disconnecting the battery cable from the negative terminal and waiting 90 seconds to avoid Air Bag engagement. Remove the front wiper arm head cap, followed by the front wiper arm and blade assemblies for both the left and right sides, then take out the cowl side ventilator sub-assemblies, cowl top ventilator louver sub-assembly, front door scuff plates, instrument panel under covers, cowl side trim boards, front door opening trim Weather Strips, front pillar garnishes, assist grip cover and sub-assembly, visor assemblies and holders, room light assembly, map light assembly, and the roof headlining assembly, which can be slightly lowered rather than completely removed. Use piano wires cut through adhesive while taping the windshield glass and insert wires through protective tape to shield the safety pad with plastic. Use suction cups to take out the windshield glass but keep as much adhesive on the vehicle body. Rinse both windshield glass and vehicle body areas to create a good joining surface without causing damage. Place new stoppers on the vehicle body and windscreen after Primer G coating dries for 3 minutes. Put Toyota Genuine Windshield Glass Adhesive with Primer G onto both the glass edges where it meets the contact surface before applying the product within its limited lifetime. Access the windshield with suction cups then place it while you match the marks and softly push down while viewing stopper attachment and windscreen body spacing. Use a scraper to clean off extra adhesive from the windscreen surface before installing the outside moulding while the sealant stays in its liquid form. Test your sealed surface after the adhesive is dry and apply auto glass sealer to fix any detected leaks. Finally, reinstall the roof headlining assembly, inner rear view mirror, map light assembly, room light assembly, visor holders and assemblies, assist grip sub-assembly and cover, front pillar garnishes, front door opening trim Weather Strips, cowl side trim boards, instrument panel under covers, front door scuff plates, cowl top ventilator louver sub-assembly, cowl side ventilator sub-assemblies, front wiper arm and blade assemblies, front wiper arm head cap, and reconnect the cable to the negative battery terminal with a torque of 5.4 N.m (55 kgf.cm, 48 in.lbf), followed by inspecting the SRS warning light.
