Radar sensorCamera sensor
Sensors
TSS combines an in-vehicle camera mounted in front of the inside rear vi\
ew mirror and
a radar mounted in the front grill. These sensors support the driver ass\
ist systems.
The Pre-Collision System uses a radar sensor and camera sensor to help d\
etect a
vehicle or pedestrian or bicyclist in front of your vehicle.
As there is a limit to the degree of recognition accuracy and control pe\
rformance 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 n\
ot use PCS
instead of normal braking operations under any circumstances. Do not att\
empt to test
the operation of the Pre-Collision System yourself, as the system may no\
t operate or
engage, possibly leading to an accident. In some situations, such as whe\
n 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 pedes\
trian 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.
Pre-Collision Warning
When the system determines that the possibility of a frontal collision i\
s high, a buzzer
will sound and a warning message will be displayed on the Multi-Informat\
ion 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 addi\
tional 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.

If the driver does not brake in a set time and the system determines tha\
t the possibility
of a frontal collision with a preceding vehicle is extremely high, the s\
ystem may
automatically apply the brakes, reducing speed in order to help the driv\
er reduce the
impact and in certain cases avoid the collision.

As part of the Pre-Collision System, this function is also designed to f\

alert and then automatic braking if needed.
Refer to a Toyota Owner’s Manual for additional limitations and infor\
mation.Under certain conditions, the PCS system included with the TSS-P package\
may
also help to detect a pedestrian in front of your vehicle using the in-v\
ehicle camera
and front-grill mounted millimeter wave radar. The in-vehicle camera of \

TOYOTA SAFETY SENSE™
LDA in TSS uses an in-vehicle camera designed to detect visible white an\
d yellow
lane markers or road edge in front of the vehicle and the vehicle’s p\
osition on the
road. If the system determines that the vehicle is starting to unintenti\
onally deviate
from its lane, the system alerts the driver with an audio and visual ale\
rt. When the
alerts occur, the driver must check the surrounding road situation and c\
arefully
operate the steering wheel to move the vehicle back to the center part o\
f their lane.

function. When enabled, if the system determines that the vehicle is on \
a path to
unintentionally depart from its lane, the system may provide small corrective steering
inputs to the steering wheel for a short period of time to help keep the\
vehicle in its
lane.
If the vehicle repeatedly deviates from the lane, the vehicle drifts wit\
hin the lane due
to inattention, or the driver abruptly operates the steering wheel after\
an inattentive
period, when enabled, the vehicle sway warning function alerts the drive\
r with an
audio and visual alert, urging them to take a break.
