  Summary

  Region Letter: The Pre-Collision System (PCS) uses a radar sensor to determine the possibility of a frontal collision. FCC regulations require the radar sensor to be temporarily inactive while the vehicle is stopped. Due to a program error in the Driving Support ECU, if the radar sensor is inactive for 10 seconds or more, the PCS may not reactivate Pre-Collision Braking on certain 2011-2014 Model Year Sienna vehicles equipped with PCS.

If the operator attempts to ready-on or start the vehicle while there is tension on the steering lock actuator, it will not be able to fully disengage when the "ENGINE START STOP" or "POWER" switch is depressed. This condition will cause the "ENGINE START STOP" or "POWER" switch's LED to flash green and the vehicle will fail to ready-on or start.

  Summary

  Toyota vehicles are equipped with either conventional or run-flat tires. Sometimes punctures may occur as a result of contact with road debris or other hazards. If a puncture occurs, it may be possible to repair the tire and return it to service. With a conventional tire it is not possible to drive for an extended amount of time with the tire at low pressures as damage to the tire may occur. With run-flat tires, due to reinforced sidewalls, it is possible to drive for up to 100 miles (160 km) at speeds less than 55 mph (90 km/h) with little or no damage to the tire.

  Summary

  Beginning in 1998, Toyota introduced side airbags as optional equipment. Toyota does NOT recommend replacement of original seat covers with non-Toyota leather or other seat cover materials on vehicles due to the following: Seat covers NOT recommended by Toyota may affect side airbag performance, in general or in part, during an accident. Modifications that negatively affect side airbag performance can result in severe occupant injuries. Seat covers are an integral part of this safety system. Replacing fabric seat covers with non-Toyota leather or other seat cover materials may compromise the effectiveness of this safety system. The design of the seat is complex, integrating safety and strength with comfort and luxury. Toyota strongly discourages modifying original equipment seats that have optional side airbags. Additionally, Toyota strongly advises against the installation or use of aftermarket seat covers, which could impair the performance of the side airbags in the event of an accident.
