THE STAR SAFETY SYSTEM IS STANDARD ON EVERY NEW MODELClick each section to learn more about Scion's Star Safety System
Vehicle Stability Control
Can help prevent slips and loss of traction. By reducing the engine power and applying brake force to the wheels that need it most, your Scion helps keep you on the road.
Anti-lock brake system
Helps to prevent brakes from locking up by "pulsing" brake pressure to each wheel to help you stay in control in emergency braking situations.
Sometimes we all need a little help. Brake Assist detects sudden or "panic" braking and adds the full pressure needed to help prevent a collision.
The name says it all. Traction Control helps maintain traction on wet, icy, loose or uneven surfaces by applying brake force to the spinning wheels.
Electronic brake-force distribution
Redistributes brake force to help keep the rear wheels from locking up during sudden braking situations.
smart stop technology ™
Is a braking system that automatically reduces engine power when both pedals are pressed at the same time under certain conditions.
Vehicle Stability Control [VSC]
Don't slip up.
VSC helps prevent two things that can cause you to lose control: front wheelslip and rear wheelslip.
VSC helps prevent wheelslip and loss of traction by reducing engine power and applying brake force to the wheels that need it. (Figure 1)
Front wheelslip can occur when the front wheels lose traction during cornering and begin to drift toward the outside of the turn. (Figure 2) Rear wheelslip can occur when the rear wheels lose traction and cause the vehicle to slide around. (Figure 3)
Scion's VSC monitors your steering angle and the direction your vehicle is being steered 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 on the path in which the vehicle was being steered.
Traction Control [TRAC]
Don't get stuck in a rut.
Traction Control helps maintain traction on wet, icy, loose and uneven surfaces.
Traction Control helps maintain traction on wet, icy, loose or uneven surfaces by applying brake force to the spinning wheel(s). (Figure 1)
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. (Figure 2)
Scion'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 on your way.
ANTI-LOCK BRAKE SYSTEM [ABS]
Don't get locked up.
ABS helps you stay in control during emergency braking situations.
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. (Figure 1)
Scion's ABS sensors detect which wheels are locking up and helps 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. (Figure 2)
This helps the wheels from locking up and that helps the car to avoid going into a skid, helping you stay in control. (Figure 3)
ELECTRONIC BRAKE-FORCE DISTRIBUTION [EBD]
Don't force it.
From amps to moving boxes, Scion's ABS technology has Electronic Brake-Force Distribution (EBD) to help keep the vehicle balanced when braking-especially if cargo is in the back.
The EBD control utilizes ABS, achieving proper brake force distribution between the front and rear wheels in accordance with the driving conditions.
If you have to stop abruptly, momentum causes the vehicle to tilt forward and reduces the brake force of the rear tires. (Figure 1)
But in a Scion, 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. (Figure 2) This helps prevent brake lockup.
BRAKE ASSIST [BA]
You've never been predictable. Neither has the road.
Brake Assist applies additional pressure to the anti-lock brakes during sudden braking.
Brake Assist is designed to detect sudden or "panic" braking and adds the full pressure needed to help prevent a collision. (Figure 1)
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.
But in a Scion, if a driver fails to apply enough pressure to the brake, the Scion Brake Assist sensors are designed to detect this sudden or "panic" braking and add pressure. (Figure 2) This additional pressure can help the driver avoid hitting the object.
SMART STOP TECHNOLOGY™ [SST]
True street smarts.
SST is included in every new Scion to help reduce engine power when both brake and gas are pressed at the same time under certain conditions.
Scion added the braking system enhancement known as Smart Stop Technology. This advanced technology automatically reduces engine power when both pedals are pressed at the same time under certain conditions.
Smart Stop Technology intervenes when the accelerator is depressed first (Figure 1) and the brakes are applied firmly for longer than one-half second at speeds greater than five miles per hour. (Figure 2)
In normal driving conditions, you won't notice Smart Stop Technology, as it is imperceptible. The feature doesn't engage if the brake pedal is depressed before the accelerator pedal.
This allows time for the driver to move from brake to acceleration when starting on a steep hill to accelerate, helping to avoid rolling backward.
Scion installed Smart Stop Technology in all models starting in 2011, making it one of the first brands to add this braking technology as standard equipment.
