Quick overview-Toyota Safety Sense™ 2.0TSS 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.
TOYOTA SAFETY SENSE™
Toyota Safety Sense™ 2.0 (TSS 2.0) is a set of active safety technologies designed
to help mitigate or prevent collisions across a wide range of traffic si\
tuations, in
certain conditions. TSS 2.0 is designed to help support the driver’s \
awareness,
decision making and vehicle operation contributing to a safe driving exp\
erience.
Refer to the Owner’s Manual for operation, setting adjustments, limitations and
more details to understand these functions and complete safety precautions. For
more information, please go to www.toyota.com/safety-sense.
The Pre-Collision System with Pedestrian Detection (PCS w/PD) is desig\
ned 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 radar and camera s\
ensors,
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 situation\
s in which the
system operation may be limited.
Pre-Collision System with Pedestrian Detection (PCS w/PD)
PCS w/PD is designed to provide alert, mitigation, and/or avoidance
support in certain conditions, when the system detects a potential
collision with a preceding vehicle is likely to occur.
The advanced grille-mounted radar system is designed to work with
the forward-facing camera to help recognize a preceding pedestrian or
bicyclist, and provide an alert, mitigation and/or avoidance support in \
certain conditions.
Lane Departure Alert with Steering Assist (LDA w/SA)
LDA w/SA is designed to provide notification when the system detects
an unintended lane departure.
The Steering Assist function is designed to provide small corrective
steering inputs to the steering wheel for a short period of time to help\

keep the vehicle in its lane.
The Sway Warning function is designed to detect vehicle swaying
(based on the vehicle location and steering wheel operation) and alert\

drivers with an audio and visual alert, urging them to take a break.
Automatic High Beams (AHB)
AHB is designed to detect the headlights of oncoming vehicles and
the tail lights of preceding vehicles and switch between high beams
and low beams as appropriate.
Road Sign Assist (RSA)
RSA is designed to recognize specific road signs using the forward-
facing camera to provide information to the driver via the display.
Full-Speed Range Dynamic Radar Cruise Control (DRCC)
Full-Speed Range DRCC is designed to help maintain a pre-set
distance to a preceding vehicle when the preceding vehicle is traveling \
at a lower speed. The minimum set speed is approximately 20 MPH,
but once activated, the operating speed range is 0-110 MPH.
Lane Tracing Assist (LTA)
LTA is designed to help keep the vehicle in the center of a lane by
assisting the driver in steering control when using Full-Speed Range
DRCC.

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\

bicyclist, preventing the system from operating or engaging.
