Driving◆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 is high, the system applies gr eater braking force in relation to
how strongly the brake pedal is depressed.
◆Pre-collision braking
When the system determ ines that the possibility of a frontal colli-
sion is high, the system warns th e driver. If the system determines
that the possibility of a frontal collision is extremely high, the brakes
are automatically applied to help avoid the collision or reduce the
collision speed.
PCS (Pre-Collision System)
The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedest rians in front of your vehicle.
When the system determines that the possibility of a frontal col-
lision with a vehicle or pedestrian is high, a warning operates to
urge the driver to take evasive action and the potential brake
pressure is increased to help the dr iver avoid the collision. If the
system determines that the possibi lity of a frontal collision with
a vehicle or pedestrian is extremely high, the brakes are auto-
matically applied to help avoid the collision or help reduce the
impact of the collision.
The pre-collision system can be disabled/enabled and the warning
timing can be changed. ( →P. 252)

2524-5. Using the driving support systems
■Enabling/disabling th e pre-collision system
The pre-collision system can be enabled/disabled on (4.2-inch
display) or (7-inch display) ( →P. 105, 119) of the multi-informa-
tion display.
The system is automatically enabled each time the power switch is
turned to ON mode.
If the system is disabled, the
PCS warning light will turn on
and a message will be dis-
played on the multi-information
display.
■Changing the pre-colli sion warning timing
The pre-collision warning timing can be changed on (4.2-inch
display) or (7-inch display) ( →P. 105, 119) of the multi-informa-
tion display.
The operation timing setting is retained when the power switch is turned
off.

■ If the PCS warning light flashes or illuminates and a warning message is
displayed on the mult i-information display
The pre-collision system may be tempor arily unavailable or there may be a
malfunction in the system.
● In the following situations, the warning light will turn off, the message will
disappear and the system will become operational when normal operating
conditions return:
• When the radar sensor or camera sensor or the area around either sen-
sor is hot, such as in the sun
• When the radar sensor or camera sensor or the area around either sen- sor is cold, such as in an extremely cold environment
• When the radar sensor or front grille emblem is dirty or covered with
snow, etc.
• When the part of the windshield in front of the camera sensor is fogged up or covered with condensation or ice
(Defogging the windshield:
→P. 348)
• If the camera sensor is obstructed, such as when the hood is open or a sticker is attached to the windshield near the camera sensor
● If the PCS warning light continues to flash or illuminate or the warning mes-
sage does not disappear, the system may be malfunctioning. Have the vehi-
cle inspected by your Toyota dealer immediately.

from its lane, a warning is dis-
played on the multi-information
display and the warning buzzer
sounds to alert the driver.
When the warning buzzer
sounds, check the surrounding
road situation and carefully
operate the steering wheel to
move the vehicle back to the
center of the lane.
◆Steering control function
When the system determines
that the vehicle might depart
from its lane, the system pro-
vides assistance as necessary
by operating the steering wheel
