The Pre-Collision System uses a radar sensor and camera sensor to help detect a
vehicle or pedestrian in front of your vehicle.
As there is a limit to the degree of recognition accuracy and control performance
that this system can provide, do not overly rely on this system. This system will not
prevent collisions or lessen collision damage or injury in every situation. Do not use
PCS instead of normal braking operations under any circumstances. Do not attempt
to test the operation of the pre-collision system yourself, as the system may not
operate or engage, possibly leading to an accident. In some situations, such as
when driving in inclement weather such as heavy rain, fog, snow or a sandstorm or
while driving on a curve and for a few seconds after driving on a curve, a vehicle
may not be detected by the radar and camera sensors, preventing the system from
operating or engaging properly.
Refer to a Toyota Owner’s Manual for a list of additional situations in which the
system may not operate properly.
Refer to a Toyota Owner’s Manual for additional information on PCS w/PD operation,
settings adjustments, limitations, and precautions before attempting to use it.
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 (MID) to urge the driver to take evasive action.
Pre-Collision Brake Assist
If the driver notices the hazard and brakes, the system may provide additional
braking force using Brake Assist. This system may prime the brakes and may apply
greater braking force in relation to how strongly the brake pedal is depressed.
Pre-Collision Braking
If the driver does not brake in a set time and the system determines that the
possibility of a frontal collision with a preceding vehicle is extremely high, the
system may automatically apply the brakes, reducing speed in order to help the
driver reduce the impact and in certain cases avoid the collision.
Pre-Collision System with Pedestrian
Detection function (PCS w/PD)
TOYOTA SAFETY SENSE ™
CHANGING THE PCS ALERT TIMING
(1) Press “ ” switches and select from the Multi-Information Display (MID).
(2) Press “ ” or “ ” switches and select from the MID and then press
“ ”. The setting screen is displayed.
(3) Press “ ” each time to change the setting. Each time it is pressed, the
response to the PCS alert timing changes as shown above. You can press “ ” to
go back to the menu.
Note: PCS is enabled each time the engine switch is turned to Ignition On.
The system can be disabled/enabled and the alert timing of the system can be
changed. (Alert timing only, brake operation remains the same).
As part of the Pre-Collision System, this function is also designed to first provide an
alert and then automatic braking if needed.
In certain conditions, the PCS system included with the TSS-P package may also
help to detect a pedestrian in front of your vehicle. With Toyota Safety Sense™ P,
PCS uses an in-vehicle camera and front-grill mounted millimeter-wave radar to
help detect a pedestrian in front of your vehicle in certain conditions. The in-vehicle
camera of PCS detects a potential pedestrian based on size, profile, and motion of
the detected pedestrian. However, a pedestrian may not be detected depending
on the conditions, including the surrounding brightness and the motion, posture,
size, and angle of the potential detected pedestrian, preventing the system from
operating or engaging. Refer to a Toyota Owner’s Manual for additional information.
PCS PEDESTRIAN DETECTION FUNCTION
Suspension control (if equipped)
When the system determines that the possibility of a frontal collision is high, the
Adaptive Variable Suspension System will control the damping force of the shock
absorbers to help maintain an appropriate vehicle posture.
