Quick overview-Toyota Safety Sense™ P (TSS-P)
Sensors
TSS-P combines an in-vehicle camera mounted in front of the inside rear \
view mirror
and a millimeter-wave radar mounted in the front grill. These sensors su\
pport the
driver assist systems.
Camera sensor
The Pre-Collision System uses a radar sensor and camera sensor to help d\
etect
vehicles and pedestrians 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 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
may not be detected by the radar and camera sensors, preventing the syst\
em 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.
Refer to a Toyota Owner’s Manual for additional information on PCS w/\
PD operation,
settings adjustments, limitations, and precautions before attempting to \
use it. 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.
Pre-Collision System with Pedestrian
Detection function (PCS w/PD)
Toyota Safety Sense™ P (TSS-P) is a set of active safety technologies designed
to help mitigate or prevent collisions across a wide range of traffic situations, in
certain conditions. TSS-P is designed to help support the driver’s aw\
areness,
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
Lane Departure Alert with Steering Assist function (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.
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. Pre-Collision System with Pedestrian Detection function (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.
Advanced millimeter-wave radar sensor system is designed
to work with the camera sensor to help recognize a preceding
pedestrian, and provide an alert, mitigation and/or avoidance
support in certain conditions.
Full-Speed Range 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.

ADJUSTING DISTANCE
To change the vehicle-to-vehicle distance

Push the “
” button to cycle
through the settings, which will
change progressively.
This mode employs a radar sensor to detect the presence of a preceding v\
ehicle
up to approximately 328 ft (100m) ahead, determines the current vehicl\
e-to-vehicle
following distance and operates to maintain a suitable following distanc\
e from the
vehicle ahead. These distances vary based on vehicle speed.

(default setting) MIDDLE SHORT
(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 vehicle is detected running ahead of you, the system automaticall\
y
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on \
at this
time). The system will respond to changes in the speed of the vehicle a\
head
in order to maintain the vehicle-to-vehicle distance set by the driver. \
A warning
tone warns you when the system cannot decelerate sufficiently to prevent your
vehicle from closing in on the vehicle ahead.
Note: Vehicle-to-vehicle distance will close in when traveling on long d\
ownhill
slopes.
TOYOTA SAFETY SENSE™
SWITCHING TO CONSTANT SPEED CONTROL MODE
Note: When your vehicle is too close to a vehicle ahead, and sufcien\
t
automatic deceleration via the cruise control is not possible, the displ\
ay will
ash and the buzzer will sound to alert the driver. An example of thi\
s would be
if another driver cuts in front of you while you are following a vehicle\
. Depress
the brake pedal to ensure an appropriate vehicle-to-vehicle distance.
If you are already using DRCC “
”, push ON-OFF button to turn the system off
first, then push and hold ON-OFF button for at least 1.5 seconds to switch.
Note: When the engine is turned off, it will automatically default to DR\
CC.
Refer to a Toyota Owner’s Manual for additional information on DRCC o\
peration,
settings adjustments, limitations, and precautions before attempting to \
use it.
(3) Acceleration when there are no longer any preceding vehicles driving
slower than the set speed The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
