2006 Lexus GS 300 Owners Manual - Page 804

OCCUPANT RESTRAINT SYSTEMS CAUTION D After inserting the tab, make sure the tab and buckle are locked and that the lap and shoulder portions of the belt and the seat belt extender are not twisted. D Do not insert coins, clips, etc. in the buckle as this may prevent you from properly latching the tab and buckle. D If the seat belt does not function normally, immediately contact your Lexus dealer. Do not use the seat until the seat belt is fixed, because it cannot protect an adult occupant or your child from death or serious injury. G16014 To connect the extender to the seat belt, insert the tab into the seat belt buckle so that the "PRESS" signs on the buckle release buttons of the extender and the seat belt are both facing outward as shown. You will hear a click when the tab locks into the buckle. When releasing the seat belt, press on the buckle release button on the extender, not on the seat belt. This helps prevent damage to the vehicle interior and extender itself. When not in use, remove the extender and store in the vehicle for future use. 158
