Pre-Collision System (PCS)
The Pre-Collision System uses a radar sensor and camera sensor to help d\
etect
vehicles and pedestrians in front of your vehicle. If the system determi\
nes that
the possibility of a frontal collision with a vehicle or pedestrian is h\
igh, the system
warns the driver to take evasive action while the potential brake pressu\
re is
increased to help the driver avoid collision or reduce the impact to the\
vehicle and
it’s occupants.
Note: PCS is enabled each time the engine switch is turned to Ignition On. Th\
e
system can be disabled/enabled and the warning timing of the system can \
be
changed.
Pre-collision warning
When the system determines that the possibility of a frontal collision i\
s high,
a buzzer will sound and a warning message will be displayed on the Multi\
-
Information Display (MID) to urge the driver to take evasive action.
Pre-collision brake assist
When the system determines that the possibility of a frontal collision i\
s high, the
system applies greater braking force in relation to how strongly the bra\
ke pedal is
depressed.
Pre-collision braking
When the system determines that the possibility of a frontal collision i\
s high, the
system warns the driver. If the system determines that the possibility o\
f a collision
is extremely high, the brakes are automatically applied to help avoid th\
e collision
or reduce the collision speed.

Preceding
vehicle mark
(1) (2) (3)
This mode employs a radar sensor to detect the presence of vehicles up t\
o
approximately 400ft (120m) ahead, determines the current vehicle-to-ve\
hicle
following distance and operates to maintain a suitable following distanc\
e from the
vehicle ahead.
(1)
Constant speed cruising when there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-\
to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis\
tance
control.
(2) Deceleration cruising and follow-up cruising when a preceding vehicle
driving slower than the set speed appears When a vehicle is detected running ahead of you, the system automaticall\
y
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on \
at this
time). The system will respond to changes in the speed of the vehicle a\
head in
order to maintain the vehicle-to-vehicle distance set by the driver. A w\
arning
tone warns you when the system cannot decelerate sufficiently to prevent\
your
vehicle from closing in on the vehicle ahead.
Note:
Vehicle-to-vehicle distance will close in when traveling on long downhi\
ll
slopes.

Smart Stop Technology automatically reduces engine power when the accele\
rator
and brake pedals are pressed simultaneously under certain conditions.
SST engages when the accelerator is depressed first and the brakes are a\
pplied
firmly for longer than one-half second at speeds greater than five miles\
per hour.
SST doesn’t engage if the brake pedal is depressed before the acceler\
ator pedal,
allowing vehicles to start on a steep hill and safely accelerate without\
rolling
backward.
Smart Stop Technology (SST)
Star Safety SystemTM
VSC helps prevent loss of traction during cornering by reducing engine p\
ower and
applying brake force to selected wheels.
Toyota’s VSC monitors steering angle and the direction your vehicle i\
s traveling.
When it senses that the front or rear wheels begin to lose traction, VSC\
reduces
engine power and applies braking to selected wheels. This helps restore \
traction
and vehicle control.
Vehicle Stability Control (VSC)
Multi Terrain Anti-lock Brake System (ABS)
Brake Assist (BA)
Helps to prevent wheel lock when the brakes are applied suddenly, or if \
the brakes
are applied while driving on a slippery road surface, or in off-road con\
ditions (such
as rough roads, sand and mud).
Brake Assist is designed to detect sudden or “panic” braking, and \
then add braking
pressure to 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. Helps to maintain drive power and prevent the 4 wheels from spinning whe\
n
starting the vehicle or accelerating on slippery roads.
Active Traction Control (A-TRAC)
Electronic Brake Force Distribution (EBD)
Toyota’s ABS technology has Electronic Brake-force Distribution (EBD\
) to help
maintain stability and balance when braking. Abrupt stops cause the vehi\
cle to tilt
forward, reducing the braking power of the rear wheels. EBD responds to \
sudden
stops by redistributing brake force to maximize the braking effectivenes\
s 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), A\
nti-lock
Braking System (ABS), Electronic Brake-force Distribution (EBD), Bra\
ke Assist (BA)
and Smart Stop Technology (SST).
