Sensors
TSS 2.0 combines a forward-facing camera mounted in front of the inside rear view
mirror and a grille-mounted radar mounted in the front grille. These sensors support
the driver assist systems.
The Pre-Collision System with Pedestrian Detection (PCS w/PD) is designed to
help detect a vehicle, a bicyclist, or a pedestrian in certain situations. Using both
a camera and radar, PCS w/ PD can provide an audio/visual alert to warn you of
a possible collision under certain circumstances. If you don’t react, the system is
designed to automatically brake.
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
or pedestrian or bicyclist may not be detected by the radar and camera sensors,
preventing the system from operating or engaging properly.
See www.toyota.com/safety-sense for more information.
Refer to the Toyota Owner’s Manual for a list of additional situations in which the
system operation may be limited.

As part of the Pre-Collision System, this function is also designed to first provide an
alert and then automatic braking if needed.

PCS PEDESTRIAN DETECTION
Under certain conditions, the PCS w/PD included with the TSS 2.0 package
may also help to detect a pedestrian or bicyclist in front of your vehicle using
the forward-facing camera and the front grille-mounted radar. The forward-
facing camera of PCS detects a potential pedestrian or bicyclist based on size,
profile, and motion of the detected pedestrian or bicyclist. However, a pedestrian
or bicyclist may not be detected depending on the conditions, including the
surrounding brightness and the motion, posture, size, and angle of the potential
detected pedestrian or bicyclist, preventing the system from operating or engaging.
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.
