TSB: All 2016 ? 2018 model year Land Cruiser and 2018 model year Sequoia, Tacoma, and Tundra vehicles are equipped with a Pre-Collision System (PCS), also known as Automatic Emergency Braking (AEB) as part of Toyota Safety Sense. The Pre-Collision System (PCS) defaults its operating mode to ON after each ignition (IG) cycle. In some driving conditions, such as extended off-road use, driving with tire chains in adverse conditions, towing another vehicle, or when your vehicle is being towed, drivers should operate the vehicle with PCS OFF. Drivers may also prefer to maintain this setting after each IG cycle. If this functionality is requested, follow the procedure in this Service Bulletin to disable the PCS mode reset after each IG cycle.
