HAC helps prevent rolling backwards on an incline. To engage, push further down
on brake pedal while at a complete stop until a beep sounds and slip indicator
illuminates. HAC holds for approximately two seconds after releasing brake pedal.

Star Safety SystemTM
VSC helps prevent loss of traction during cornering by reducing power from the EV
System and applying brake force to selected wheels.
Toyota’s VSC monitors steering angle and the direction your vehicle is traveling.
When it senses that the front or rear wheels begin to lose traction, VSC reduces
power from the EV System and applies braking to selected wheels. This helps
restore traction and vehicle control.
Vehicle Stability Control (VSC)
Anti-Lock Brake System (ABS)
ABS helps prevent brakes from locking up by “pulsing” brake pressure to each
wheel. This limits brake lockup and helps provide directional control for the
current road conditions.
Toyota’s ABS sensors detect which wheels are locking up and limits wheel lockup
by “pulsing” each wheel’s brakes independently. Pulsing releases brake pressure
repeatedly for fractions of a second. This helps the tires attain the traction that
current road conditions will allow, helping you to stay in directional control.
Brake Assist (BA)
Brake Assist is designed to detect sudden or “panic” braking, and then add braking
pressure to help decrease the vehicle’s stopping distance. When there’s only a
split second to react, Brake Assist can add additional brake pressure more quickly
than just the driver alone can. VSC helps prevent loss of traction during cornering by reducing power from the EV
System, and Traction Control helps maintain traction on loose gravel and wet, icy,
or uneven surfaces by applying brake force to the spinning wheel(s).
Toyota’s TRAC sensors are activated when one of the drive wheels starts to slip.
TRAC limits motor output and applies the brakes to the spinning wheel. This
transfers power to the wheels that still have traction to help keep you on track.
Traction Control (TRAC)
Electronic Brake Force Distribution (EBD)
Toyota’s ABS technology has Electronic Brake-force Distribution (EBD) to help
maintain control and balance when braking. Abrupt stops can cause a vehicle
to tilt forward, reducing the braking power of the rear wheels. EBD responds to
sudden stops by redistributing brake force to enhance the braking effectiveness of
all four wheels.
SAFETY AND EMERGENCY FEATURES
All new Toyota vehicles come standard with the Star Safety SystemTM, which
combines Vehicle Stability Control (VSC), Traction Control (TRAC), Anti-lock Braking
System (ABS), Electronic Brake-force Distribution (EBD), Brake Assist (BA) and Smart
Stop Technology (SST).
