Grille-mounted radarForward-facing camera
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 sen\
sors 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 situation\
s. 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 pe\
rformance
that this system can provide, do not overly rely on this system. This sy\
stem will not
prevent collisions or lessen collision damage or injury in every situati\
on. 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 syste\
m 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 san\
dstorm 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 grille-mounted rad\
ar and
forward-facing camera, preventing the system from operating or engaging \
properly.
See Toyota.com/safety-sense for more information.
Refer to the Toyota Owner’s Manual for a list of additional situation\
s in which the
system operation may be limited.

PRE-COLLISION SYSTEM (CONTINUED)
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-I\
nformation
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 m\
ay apply
greater braking force in relation to how strongly the brake pedal is dep\
ressed.
Pre-Collision Braking
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
system may automatically apply the brakes, reducing speed in order to he\
lp the
driver reduce the impact and in certain cases avoid the collision.
Refer to the Toyota Owner’s Manual for additional information on PCS \
operation,
settings adjustments, limitations, and precautions before attempting to \
use it.
Monocular camera sensorMillimeter
wave radar
As part of the Pre-Collision System, this function is also designed to f\
irst provide an
alert and then automatic braking if needed.
Refer to the Toyota Owner’s Manual for additional limitations and inf\
ormation.Under certain conditions, the PCS system included with the TSS 2.0 packa\
ge
may also help to detect a pedestrian or bicyclist in front of your vehic\
le using the
forward-facing camera and 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 bicycl\
ist may not
be detected depending on the conditions, including the surrounding brigh\
tness
and the motion, posture, size, and angle of the potential detected pedes\
trian or
bicyclist, preventing the system from operating or engaging.

By detecting visible white/yellow lane markings or the road’s edge at\
speeds above
32 mph, Lane Departure Alert with Steering Assist (LDA w/SA) is designed to issue
an audio/visual alert if an inadvertent lane departure is detected. If t\
he driver does
not take corrective action, the Steering Assist function is designed to \
provide gentle
corrective steering.*
* See Toyota.com/safety-sense for more information.
