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 http://www.toyota.com/safety-sense
Quick overview-Toyota Safety Sense™ 2.0
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
the driver 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.
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 millimeter-wave radar sensor system is designed to work
with the camera sensor to help recognize a preceding pedestrian or
bicyclist, and provide an alert, mitigation and/or avoidance support in \
certain conditions.
Dynamic Radar Cruise Control (DRCC)
DRCC is designed to help maintain a pre-set distance to a preceding
vehicle when the preceding vehicle is traveling at a lower speed.

31
Radar sensorCamera sensor
Sensors
TSS 2.0 combines an in-vehicle camera mounted in front of the inside rea\
r view mirror
and a radar mounted in the front grill. These sensors support the driver\
assist 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 or bicyclist
may not be detected by the radar and camera sensors, preventing the syst\
em from
operating or engaging properly.
Refer to the Toyota Owner’s Manual for a list of additional situation\
s 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.

PRE-COLLISION SYSTEM (CONTINUED)
TOYOTA SAFETY SENSE™
Refer to the Toyota Owner’s Manual for additional information on PCS \
operation,
settings adjustments, limitations, and precautions before attempting to \
use it. 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 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.
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
in-vehicle camera and front grille-mounted radar. The in-vehicle 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 brigh\
tness
and the motion, posture, size, and angle of the potential detected pedestrian
or
bicyclist, preventing the system from operating or engaging.

TOYOTA SAFETY SENSE™
LDA in TSS 2.0 uses an in-vehicle camera designed to detect visible whit\
e and
yellow lane markers or road edge in front of the vehicle and the vehicle\
’s position
on the road. If the system determines that the vehicle is starting to un\
intentionally
deviate from its lane, the system alerts the driver with an audio and vi\
sual alert.
When the alerts occur, the driver must check the surrounding road situat\
ion and
carefully operate the steering wheel to move the vehicle back to the cen\
ter part of
their lane.
LDA is designed to function at speeds of approximately 32 mph (50 km/h) or higher
on relatively straight roadways.
In addition to the alert function, LDA w/SA also features a steering ass\
ist
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.

Note: Operation of the LDA system and setting adjustments continues in the
same condition regardless of Ignition cycle until changed by the driver or the
system is reset.
