| T-SB-0040-08 | 2017-08-14. Service bulletin. STRUCTURE:BODY. TSB: On some vehicles, when Rapgard is removed, the paint may have a stained appearance. These stains appear to be under the clear coat (repainting this area is not necessary). The stain patterns are usually under wrinkles in the Rapgard. These wrinkles sometimes trap water and cause the paint to stain from the trapped moisture, especially on horizontal surfaces, such as the hood, roof, and trunk. Stains can be removed by heating the stained surface to remove the trapped moisture. |
| F0B_LSC_Dealer L | 2017-08-14. Service bulletin. AIR BAGS:FRONTAL:SENSOR/CONTROL MODULE-INACTIVE; AIR BAGS. Dealer Letter: The front passenger seat assembly is equipped with sensors for the occupant classification system which are used to control the operation of supplemental restraint systems (SRS), including the front passenger airbag. The sensors classify the weight of the occupant and activate or deactivate the front passenger airbag accordingly. Additionally, the sensors are used to detect certain vehicle collisions. Due to the current collision detection thresholds, the system may interpret certain occupant seating usages or road conditions as a rear collision and illuminate the Airbag Warning Light and "AIR BAG OFF" indicator, disabling the front passenger air bag. This LSC will be available until December 31, 2017, and will only be available at an authorized Toyota Dealer. |
