Star Safety System™
The 2012 Sienna comes standard with the Star Safety System™. This integration of active safety features is designed to protect occupants by helping drivers avoid accidents in the first place. The Star Safety System™ includes Vehicle Stability Control (VSC),1 Traction Control (TRAC), Anti-lock Brake System (ABS), Electronic Brake-force Distribution (EBD), Brake Assist (BA)2 and Smart Stop Technology (SST).3
1 Vehicle Stability Control (VSC) is an electronic system designed to help the driver maintain vehicle control under adverse conditions. It is not a substitute for safe driving practices. Factors including speed, road conditions and driver steering input can all affect whether VSC will be effective in preventing a loss of control.
2 Brake Assist is (BA) designed to help the driver take full advantage of the benefits of Anti-Lock Brake System (ABS). It is not a substitute for safe driving practices. Braking effectiveness also depends on proper brake-system maintenance and tire and road conditions.
3 Smart Stop Technology (SST) operates only in the event of certain simultaneous brake and gas pedal applications. When engaged, the system will reduce engine power to help the brakes bring the vehicle to a stop. Factors including speed, road conditions and driver input can all impact stopping distance. Smart Stop Technology is not a substitute for safe and attentive driving and does not guarantee instant stopping.
