Toyota Star Safety System
Toyota Star Safety System comes standard on all new vehicles.
Anti-Lock Brake System (ABS)
ABS helps prevent brakes from locking up by “pulsing” brake pressure to each wheel to help you stay in control in emergency braking situations. When something unexpected appears in your path, you instinctively swerve to avoid it and jam on the brakes. However, without ABS, the brakes can lock up, the vehicle starts to skid, and you struggle to stay in control. Toyota’s ABS sensors detect which wheels are locking up and prevent the lockup by “pulsing” the brakes at each wheel independently. Pulsing releases brake pressure repeatedly for fractions of a second – a reaction time not possible for humans. This means the wheels never stop rotating and that helps the car to avoid going into a skid, helping you stay in control.
Electronic Brake-Force Distribution (EBD)
Toyota’s ABS technology has Electronic Brake-force Distribution (EBD) to help keep the vehicle more stable and balanced when braking. If you have to stop abruptly, momentum causes the vehicle to tilt forward and reduces the brake force of the rear tires. But in a Toyota, EBD responds to sudden stops by redistributing brake force. Wheels with more braking effectiveness receive more brake force; wheels with less effectiveness receive less brake force. This helps prevent brake lockup. EBD is especially helpful when carrying cargo. Sensors recognize the extra load the cargo puts on the rear axle, so brake pressure on the rear wheels is increased because the extra weight improves braking effectiveness.
Brake Assist (BA)
Brake Assist is designed to detect sudden or “panic” braking and adds the full pressure needed to help prevent a collision. If something rolls out into the street in front of a vehicle, there’s only a split second to react. Because the reaction time is so short before the driver hits the brakes, not enough pressure may be applied. As a result, the car may not stop in time. But in a Toyota, if a driver fails to apply enough pressure to the brake, the Brake Assist sensors will detect this sudden or “panic” braking and add pressure. This additional pressure can help the driver avoid hitting the object.
Traction Control (TRAC)
Traction Control helps maintain traction on wet, icy, loose or uneven surfaces by applying brake force to the spinning wheel(s). Let’s say you’re driving and come upon a snowy or icy patch on an uneven road. If your vehicle gets stuck in the snow, wheelspin occurs, and you come to a stop. Toyota’s Traction Control sensors are activated when one of the wheels starts to slip. TRAC limits engine output and applies the brakes to the spinning wheel. (Figure 3) This transfers power to the wheels that still have traction to help you go safely on your way.
Vehicle Stability Control (VSC)
VSC helps prevent wheel slip and loss of traction by reducing engine power and applying brake force to the wheels that need it. Front wheel slip can occur when the front wheels lose traction during cornering and begin to drift toward the outside of the turn. Rear wheel slip can occur when the rear wheels lose traction and cause the vehicle to slide around. Toyota’s VSC monitors your steering angle and the direction your vehicle is actually traveling and senses when your front or rear wheels begin to slip. When it senses this loss of traction or slip, VSC reduces engine power and applies braking to the individual wheels that need it to help correct the slip and keep the vehicle in the intended path.
Smart Stop Technology (SST)
Smart Stop Technology® operates in the event of certain contemporaneous brake and accelerator pedal applications. When engaged, the system will reduce 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 substitute for safe and attentive driving and does not guarantee instant stopping. See Owner’s Manual for more details.
