PCS (Pre-Collision System)
■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 is high, the system applies greater braking force
in relation to how strongly the brake pedal is depressed.
■ Pre-collision braking
When the system determines that the possibility of a frontal colli-
sion with a vehicle is high, the system warns the driver. If the sys-
tem determines that the possibility of a collision is extremely high,
the brakes are automatically applied to help avoid the collision or
reduce the collision speed.
: If equipped
The pre-collision system uses the front sensor to detect vehicles in
front of your vehicle. When the system determines that the possibil-
ity of a frontal collision with a vehicle is high, warning operates to
urge the driver to take evasive action and the potential brake pres-
sure is increased to help the driver avoid the collision. If the system
determines that the possibility of a frontal collision with a vehicle is
extremely high, the brakes are automatically 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 tim-
ing can be changed. ( P. 272)

When driving
VERSO_EE_OM64517E
• If the wheels are misaligned
• If a wiper blade is blocking the front sensor
• The vehicle is wobbling.
• The vehicle is being driven at extremely high speeds.
• When driving on roads with sharp bends or uneven surfaces
• When a preceding vehicle is a poor reflector of laser
● In some situations such as the following, sufficient braking force 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 extremel y cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are exces-
sively worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery
surface
• If your vehicle is skidding
• When the front part of the vehicle
is raised or lowered
• When the sensor is misaligned
due to a strong impact being
applied to the sensor, etc.

■ If the PCS warning light flashes or illuminates, and a warning message is
displayed on the multi-information display
The pre-collision system may be tem porarily 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 becom e operational when normal operating
conditions return:
• When the area around the front sensor is hot, such as in the sun
• When the windshield is fogged up or covered with condensation or ice
( P. 340, 350)
• When the front sensor or the area ar ound either sensor is cold, such as
in an extremely cold environment
• If the area in front of the front sensor is obstructed, such as when the
hood is open
● If the PCS warning light continues to flash or illuminate, or the warning
message does not disappear, the system may be malfunctioning. Have the
vehicle inspected by any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional immediately.
■ If VSC is disabled
● If TRC and VSC+ are disabled (P. 318), the pre-collision brake assist
and pre-collision braking functions are also disabled. However, the pre-col-
lision warning function will still operate.
● The PCS warning light illuminates and “VSC TURNED OFF PRE-COLLI-
SION BRAKE SYSTEM UNAVAILABLE” is displayed on the multi-informa-
tion display. ( P. 5 5 1 )

2-5. Using other driving systems
VERSO_EE_OM64517E
■ Sensor detection information
● Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicl es, or other loud noises producing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• Towing eyelet is installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• A non-genuine Toyota suspension (lowered suspension etc.) is
installed.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.
● The shape of the obstacle may prevent a sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angles objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle

*2

Indicates that, since
the VSC (Vehicle Sta-
bility Control) system
was turned off, the
pre-collision braking
and pre-collision
brake assist are dis-
abled (The pre-colli-
sion warning function
will be operational)
Turn the VSC on.
( P. 282318)
The system is tempo-
rarily canceled
because the operating
conditions of the front
sensor (temperature,
etc.) are not met.
The following systems
may be suspended:
• PCS (Pre-Collision
System) (if equipped).
• LDA (Lane Departure
Alert) (if equipped);
• Automatic High Beam
(if equipped)
The system can be
operated when the
operating conditions of
the front sensor (tem-
perature, etc.) are met.
Turn the system off,
wait for a while, and
then turn the system
back on.
The area of the wind-
shield 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) (if equipped).
• LDA (Lane Departure
Alert) (if equipped);
• Automatic High Beam
(if equipped)
Turn the system off,
clear the windshield of
dirt, fog, ice, etc. then
turn the system back
on. ( P. 265)
