FEATURES & OPERATIONS
Pre-Collision System (PCS)
When a high possibility of a frontal collision is detected by the radar \
sensor, a
buzzer sounds and a message urging the driver to take evasive action app\
ears on
the multi-information display. If the driver then applies brakes, the s\
ystem applies
greater brake force in relation to how strongly the brake pedal is depre\
ssed. If
the system determines that a collision is unavoidable, the brakes are au\
tomatically
applied to reduce the collision speed. The system is enabled each time t\
he power
switch is turned to ON mode.
Refer to the Owner‘s Manual for more details on this system before at\
tempting to
use it.Each time the Pre-Collision System switch is pressed, the response to th\
e distance
changes as follows:
Press the PCS switch for 3 seconds or more.

SAFETY & EMERGENCY FEATURES
Star Safety System™
Enhanced Vehicle Stability Control provides cooperative control of the A\
BS, TRAC,
VSC and EPS.
Enhanced VSC helps to maintain directional stability when loss of tracti\
on occurs
during a turn.
VSC helps prevent loss of traction during cornering by reducing Motor po\
wer
output, 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 star\
ts to slip.
TRAC limits Motor power output and applies the brakes to the spinning wh\
eel. This
transfers power to the wheels that still have traction to help keep you \
on track.
Toyota’s ABS sensors detect which wheels are locking up and limits wh\
eel lockup
by “pulsing” each wheel’s brakes independently. Pulsing release\
s brake pressure
repeatedly for fractions of a second. This helps the tires attain the tr\
action that
current road conditions will allow, helping you to stay in directional c\
ontrol.
Toyota’s ABS technology has Electronic Brake-force Distribution (EBD\
) to help
maintain control and balance when braking. Abrupt stops can cause a vehi\
cle 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. All new Toyota vehicles come standard with the Star Safety System
TM, which
combines Vehicle Stability Control (VSC), Traction Control (TRAC), Anti-lock Braking
System (ABS), Electronic Brake-force Distribution (EBD), Brake Assis\
t (BA) and
Smart Stop Technology (SST).
Refer to the Owner’s Manual for more details and important information on limitations
to these systems.
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 qui\
ckly than
just the driver alone can.
Smart Stop Technology automatically reduces driving torque when the acce\
lerator
and brake pedals are pressed simultaneously under certain conditions.
