FEATURES & OPERATIONSBlind Spot Monitor with Rear Cross Traffic
Alert (BSM w/RCTA)
The Blind Spot Monitor is a system that has two functions:
• The Blind Spot Monitor function (assists the driver in making the decision when to
change lanes)
• The Rear Cross Traffic Alert function (assists the driver when backing up)
The system is designed to use radar sensors to detect vehicles traveling\
in the
Mirai’s blind spot. If a vehicle is detected, the driver will be aler\
ted via the outside
rear view side mirror indicators.
Rear Cross Traffic Alert function:
While in reverse, when a vehicle approaching from the right or left rear\
of the Mirai
is detected, the outside rear view mirror indicators flash.
Refer to the Owner‘s Manual for limitation and more details on this s\
ystem before
attempting to use it.

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.

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.

(1) The system displays solid white lines on the LDA indicator when visible lane
markers on the road are detected. A side flashes orange to alert the dri\
ver when the
vehicle deviates from its lane.
(2) The system displays outlines on the LDA indicator when lane markers on the road
are not detected or the function is temporarily cancelled.
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.
Refer to the Toyota Owner’s Manual for additional information on LDA \
operation,
settings adjustments, limitations, and precautions before attempting to \
use it.

lp prevent
swaying, the system alerts the driver using a buzzer sound and a warning displays
in the MID.
Continuous lane deviations from
