See and be seen. That is a big part of the safety philosophy – and its why Limited models feature the advanced functionality of Automatic Headlamps that automatically turn on Sienna\'s headlamps in response to waning daylight.

Anti-lock Brakes with Electronic Brake-force Distribution (EBD) are standard on all models. Sensors monitor speed, traction, vehicle load and the driver\'s applied brake-force to aid in delivering maximum braking power - especially in emergency braking situations.

3-point Lap and Shoulder Belts help protect all passengers, while driver and front passenger are further protected by Seatbelt Pretensioners and Force-limiters. Standard Dual Stage Front Airbags, Front Seat Mounted Side Airbags and Front and Rear Head / Side Curtain help to provide maximum safety for all three rows of passengers.

Imagine a Cruise Control System that uses a Laser Radar Beam to measure the distance from the car ahead, automatically adjusting vehicle speed to help maintain a safe distance. Science fiction? Of course not, it\'s Sienna Limited All Wheel Drive!

Both Front Wheel and All Wheel Drive models offer available Vehicle Stability Control (VSC) with Traction Control (TRAC). The system helps to control both brake-force and the torque going to each wheel. Under- and oversteering are corrected, while wheel spin is minimized. Just one more example of Toyota\'s continuous improvement philosophy in action.
