VEHICLE STABILITY CONTROL (VSC)1
VSC helps prevent two factors that can cause drivers
to lose control during cornering: front wheelslip and
rear wheelslip. VSC monitors your steering angle and
compares it to the direction in which your vehicle is
actually traveling. If VSC detects a loss of traction,
two things happen to help correct the problem: First,
engine output is reduced; then, brake force is applied
to individual wheels as needed.
TRACTION CONTROL (TRAC)
TRAC helps maintain traction on wet, icy, loose or
uneven surfaces. Like VSC, TRAC applies braking
individually and reduces engine output to help assist
the driver with control of the vehicle.
Possible Scenario
WITHOUT TRAC WITH TRAC
4-WHEEL ANTI-LOCK BRAKE SYSTEM (ABS)
ABS helps ensure that you’re able to continue
steering during emergency braking. By “pulsing”
the brake of each wheel more rapidly than would
be humanly possible, ABS helps keep the brakes
from locking up. Since the system repeatedly
releases the brakes for fractions of a second, the
wheels never stop rotating, which helps keep the
vehicle from going into a skid.
ELECTRONIC BRAKE-FORCE DISTRIBUTION (EBD)
EBD helps keep the vehicle balanced when braking.
During sudden stops, forward momentum causes the
vehicle to tilt forward, reducing the brake effectiveness
of the rear wheels. EBD responds by redistributing brake
force from wheels with less braking effectiveness
to wheels with more effectiveness. This helps prevent
brake lockup. EBD is especially helpful when carrying
cargo. When sensors detect extra load on the rear
axle, brake pressure on the rear wheels is increased,
exploiting the improved braking effectiveness extra
weight can provide.
BRAKE ASSIST (BA)2
In emergency braking situations, a driver could fail
to apply enough pressure to the brake pedal. BA
can detect sudden or “panic” braking and apply
additional brake pressure, taking full advantage
of ABS and helping prevent a collision.
SMART STOP TECHNOLOGY (SST)3
At speeds greater than five miles per hour, when the
accelerator is depressed first and the brakes are
then applied firmly for longer than one-half second,
SST is designed to help the driver bring the vehicle to
a complete stop.

Toyota’s Star Safety System™ is a suite of six safety features offered
standard on every new Toyota. The system includes Vehicle Stability
Control (VSC),
1 Traction Control (TRAC), Anti-lock Brake System (ABS),
Electronic Brake-force Distribution (EBD), Brake Assist (BA)2 and
Smart Stop Technology (SST).
3 Termed “active” safety features, they’re
designed to operate in certain situations to help prevent accidents from
occurring in the first place.
