TOYOTA SAFETY SENSE™
Toyota Safety Sense™ 2.5+ (TSS 2.5+) is a set of active safety technologies
designed to help mitigate or prevent collisions across a wide range of t\
raffic
situations, in certain conditions. TSS 2.5+ is designed to help support \
the driver’s
awareness, decision making and vehicle operation contributing to a safe \
driving
experience.
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.
Quick overview-Toyota Safety Sense™ 2.5+
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.
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 sensor 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.
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.

Grille-mounted radarForward-facing camera
Sensors
TSS 2.5+ 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 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 (CONTINUED)
TOYOTA SAFETY SENSE™
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-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 2.5+ pack\
age
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, profil\
e, 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.

ADJUSTING DISTANCE
This mode employs a radar sensor to detect the presence of a preceding v\
ehicle
up to approximately 328 ft (100 m) ahead, determines the current vehic\
le-to-vehicle
following distance and operates to maintain a preset following distance \
from the
vehicle ahead. These distances vary based on vehicle speed.
(1) (2) (3)
(1) Constant speed cruising when there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-\
to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis\
tance
control.
(2) Deceleration cruising and follow-up cruising when a preceding vehicle
driving slower than the set speed appears When a slower vehicle is detected running ahead of you, the system
automatically decelerates your vehicle. When a greater reduction in vehi\
cle
speed is necessary, the system may apply the brakes (the brake lights w\
ill
come on at this time). The system will respond to changes in the speed \
of the
vehicle ahead in order to maintain the vehicle-to-vehicle distance set b\
y the
driver. A warning tone warns you when the system cannot decelerate suffi\
ciently
to prevent your vehicle from closing in on the vehicle ahead.
Note: Vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.
