VSC helps prevent wheelslip and loss of traction by reducing engine power and applying brake force to the wheels that need it. (Figure 1) Rear wheelslip can occur when the rear wheels lose traction and cause the vehicle to slide around.(Figure 2) Front wheelslip can occur when the front wheels lose traction during cornering and begin to drift toward the outside of the turn. 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.

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. (Figure 2) If your vehicle gets stuck in the snow, wheelspin occurs, and you come to a stop. (Figure 1) 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. This transfers power to the wheels that still have traction to help you go safely on your way.

ANTI-LOCK BRAKES (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 may 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.

1. Inexperienced or panicking driver applies brakes quickly but without enough pressure. 2. Driver sometimes eases up on the brake pedal too soon. 3. The Brake Assist system increases braking force, even when the brake pedal isn?t pushed hard enough. 4. When the driver intentionally eases up on the brake pedal, the Brake Assist system reduces the amount of assistance applied. Note: To activate the Brake Assist system, keep pressing the brake pedal. When braking assistance is no longer required, ease up on the brake pedal.

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.
