The system can detect the following:
P. 2 3 2
● Vehicles
● Pedestrians
■Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
■Pre-collision brake assist
When the system determines that the possibility of a frontal colli-
sion with a vehicle or pedestrian is high, the system applies greater
braking force in relation to how strongly the brake pedal is
depressed.
PCS (Pre-Collision System)
The pre-collision system uses the front sensor to detect objects
(  P. 229) in front of the vehicle. When the system determines
that the possibility of a front al collision with an object is h igh, a
warning operates to urge the driver to take evasive action and
the potential brake pressure is increased to help the driver av oid
the collision. If the system determines that the possibility of a
frontal collision with an object i s extremely high, the brakes are
automatically applied to help av oid the collision or help reduce
the impact of the collision.
The pre-collision system can b e disabled/enabled and the warnin g
timing can be changed. ( P. 2 3 2 )

PRIUS c_U• If the wheels are misaligned
• If a wiper blade is blocking the camera sensor
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• When there is a laser reflecting object (manhole cover, reflec
tive plate,
etc.), steps, or a protrusion in front of your vehicle
• If the radar sensor or camera sensor is misaligned
● In some situations such as the following, sufficient braking fo rce may not be
obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other sli ppery sur-
face
■ If VSC is disabled
●If VSC is disabled ( P. 265), the pre-collision brake assist and pre-collision
braking functions are also disabled.
● The PCS warning light will turn on and “VSC TURNED OFF PRE-COLL I-
SION BRAKE SYSTEM UNAVAILABLE” will be displayed on the multi-i nfor-
mation display. • If the front of the vehicle is raised or
lowered

PRIUS c_U
Indicates that the accelerator and brake pedals
are being depressed simultaneously, and the
Brake Override System is operating. (P. 171)
 Release the accelerator pedal and depress
the brake pedal.
Indicates that, as the shift lever was shifted while
the accelerator pedal was depressed, Drive-Start
Control was activated. ( P. 171)
A buzzer also sounds.
 Release the accelerator pedal immediately.
Indicates that the accelerator pedal is depressed
with the shift lever in P
 Release the accelerator pedal.
The system is temporarily canceled because the
operating conditions of the front sensor (tempera-
ture, etc.) are not met.
The following systems may be suspended:
• PCS (Pre-Collision system)
• LDA (Lane Departure Alert)
• Automatic High Beam
The system can be operated when the
operating conditions of the front sensor
(temperature, etc.) ar e met. Turn the system
off, wait for a while, and then turn the sys-
tem back on.
The area of the windshield in front of the front
sensor is fogged up or covered with dirt, rain, ice,
snow, etc.
The following systems may be suspended:
• PCS (Pre-Collision system)
• LDA (Lane Departure Alert)
• Automatic High Beam
 Turn the system off, clear the windshield of
dirt, fog, ice, etc. then turn the system back
on. ( P. 226)
