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
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.Quick overview-Toyota Safety Sense™ 2.0
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.
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.
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.

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.

TURNING THE LDA SYSTEM ON/OFF
Press the LDA switch to turn the LDA system on. Depress again to turn it\
 off.
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.
Refer to the Toyota Owner’s Manual for additional information on LDA \
operation, 
settings adjustments, limitations, and precautions before attempting to \
use it.

Note: When operation conditions are no longer met, a function may be 
temporarily canceled. However, when the operation conditions are met again, 
operation of the function is automatically restored. For example, LDA may not 
function on the side(s) where white/yellow lines are not detectable.
