warning light TOYOTA 86 2022 Workshop Manual

1864-5. EyeSight
When there is an obstacle in front of you during driving, the system
activates in the following sequence in order to warn the driver and to
activate braking control and the stop lights.
Following distance warning:
When the system determines that t here is a risk of collision, an alert sounds
repeated short beeps and the indicators on the meter display il luminate to
warn the driver.
The Following Distance Warning ope rates when Adaptive Cruise Control is
not activated.
When the driver depresses the bra ke pedal to decelerate and achieves a
suitable following distanc e, the warning is canceled.
First braking and warning:
When the system determines that there is a high risk of collisi on with an
obstacle in front, an alert sounds repeated short beeps and the indicators
on the meter display illuminate to warn the driver. Braking control may be
activated and in some situations, engine output may also be controlled. If
the system determines that the amount of evasive action (brakin g, steering,
etc.) taken by the driver has reduced the risk of collision, br aking activation
is canceled.
Secondary braking and warning:
WARNING
The EyeSight system’s Pre-Colli-
sion Braking function also identi-
fies pedestrians as obstacles.
However, depending on the con-
ditions, there may be cases when
the system cannot detect a
pedestrian. In the following condi-
tions, the possibility that the sys-
tem may not be able to detect a
pedestrian as an object is particu-
larly high.
●Pedestrians are walking in a
group.
●A pedestrian is next to a wall or
other obstacle.
●A pedestrian is using an
umbrella.
●A pedestrian is wearing clothes
that are a similar color to the
surrounding environment.
●A pedestrian is carrying bulky
luggage.
●A pedestrian is bent over,
crouching down o r lying down.
●A pedestrian is in a dark loca-
tion.
●A pedestrian suddenly crosses
in front of you from the side or
suddenly runs in front of you.

Adaptive Cruise Control is
designed for use on expressways,
freeways, toll roads, interstate
highways and similar limited
access roads. It is not intended to
be used in city traffic. In the fol-
lowing conditions, do not use
Adaptive Cruise Control. Doing so
may result in an accident.
●Ordinary roads (roads other
than those mentioned above)
• Depending on the driving envi- ronment (complexity of roads
and other factors), the system
may not be able to perform as
the traffic conditions require,
and that may result in an acci-
dent.
●Sharp curves or winding roads

WARNING
●The windshield has become
fogged, scratched or smeared,
or snow, dirt, dust or frost has
adhered to it, or it is otherwise
affected. These will reduce the
stereo camera’s field of view.
Also, light is reflecting off the
dirt, etc.
●Water droplets from rain or the
window washer, or dirt has not
been fully wiped off the wind-
shield.
• It may not be po ssible to detect
the vehicle in front, making cor-
rect control impossible.
●The stereo camera’s field of
view is obstructed.
The stereo camera may have diffi-
culty detectin g the following
objects or conditions. Operate the
brake pedal and take other
actions as necessary.
●Vehicles at significantly different
speeds (vehicles driving slowly,
stopped or oncoming vehicles,
etc.)
●Vehicles cutting into your lane
●Motorcycles, bicycles, pedestri-
ans and animals, etc.
●Light is poor in the evening or
early morning.
●At night or in a tunnel without
the headlights on
●At night or in a tunnel when
there is a vehicle in front that
does not have its tail lights on
●Strong light is coming from the
front (sunlight or headlight high
beams, etc.).
●Vehicles in front that have a rear
aspect that is low, small or irreg-
ular (the system may recognize
another part of the vehicle and
will determine operation from
that)
• An empty truck or trailer that has no tailgate or longbed
• Vehicles that have cargo pro- truding from their back ends
• Non-standard shaped vehicles (vehicle transporters or vehi-
cles with a sideca r fitted, etc.)
• Vehicles that are low
●Objects that are located close to
the bumper of your vehicle
■Detection of the vehicle in
front by the EyeSight stereo
camera
*
●Under the following road condi-
tions or conditions of your vehi-
cle, detection of the vehicle in
front may not be possible. Vehi-
cles in neighboring traffic lanes
or roadside objects may also be
incorrectly detected. Under con-
ditions such as these, do not
use Adaptive Cruise Control. If
cruise control is currently in use,
operate the brake pedal and
take other actions as necessary.

optimal following distance.
Vehicles in front in the same traffic
lane are detected by the stereo
camera within a distance of approxi-
mately 360 ft (110 m) in the forward
direction. However the detection
distance may be reduced depending
on the traffic environment, driving
conditions, and conditions of the
vehicle in front.
WARNING
●If the alert/notification sounds
frequently, do not use Adaptive
Cruise Control.
●The “Obstacle Detected” warn-
ing will not activate in the follow-
ing situations.
• The accelerator pedal is depressed.
• The brake pedal is depressed.
●Even when the following dis-
tance is short, the “Obstacle
Detected” warning may not acti-
vate in the following situations.
• The difference in speed with the vehicle in front is small. The two
vehicles are traveling at almost
the same speed.
• The vehicle in fr ont is traveling
faster than your vehicle. The fol-
lowing distance is gradually
increasing.
• Another vehicle cuts into your lane very close to your vehicle.
• The vehicle in fr ont decelerates
suddenly.
• There are rep eated uphill and
downhill grades.
●The “Obstacle Detected” warn-
ing may not activ ate in time in
the case of a v ehicle that is
stopped at the end of a line at a
toll gate, at a stop light or inter-
section or in traf fic congestion,
or a vehicle that is moving much
slower than your vehicle. Eye-
Sight requires a speed differen-
tial in order to recognize a
potential obstacle and react to
it.

2164-5. EyeSight
WARNING
●If your vehicle is trapped on a
railroad crossing and you are
trying to escape by driving
through the crossing gate, the
stereo camera may recognize
the crossing gate as an obstacle
and Pre-Collision Throttle Man-
agement system may activate.
In this case, remain calm and
either continue to depress the
accelerator pedal or turn off the
Pre-Collision Throttle Manage-
ment system. (
P.218)
Pre-Collision Throttle Manage-
ment may not activate depending
on the following conditions:
●The distance between your
vehicle and the obstacle, speed
difference, and horizontal offset
●Recognition status of the stereo
camera
In particular, the function may not
activate in the following cases:
• Bad weather (for example heavy rain, a blizzard or thick
fog)
• Visibility is poor due to sand or smoke in the air.
• Light is poor in the evening, early morning, or at night.
• In a dark area (indoor parking area, etc.)
• There is an obstacle outside the area illuminated by the head-
lights.
• Strong light is coming from the front (for example sunlight at
sunrise or sunset headlight
beams, etc.).
• The windshield has become fogged, scratched or smeared,
or snow, dirt, dust or frost has
adhered to it, or it is otherwise
affected. These will reduce the
stereo camera’s field of view.
Also, light is reflecting off the
dirt, etc.
• Fluid has not been fully wiped off the windshield during or after
use of the window washer.
• Obstacles cannot be correctly recognized due to water drop-
lets from rain or the washer, or
the wiper blades obstructing the
stereo camera’s field of view.
• The stereo came ra’s field of
view is obstructed.
• With low obstacles (low wall, crash barrier, low vehicle, etc.)
• The size and height of an obsta- cle is smaller than the limita-
tions of the stereo camera’s
recognition capability. (Small
animals, children, pedestrians
who are sitting or lying down,
etc.)
• The rear portion nearest your vehicle is too small or too close
(such as a trailer or oncoming
vehicle). The system may not
recognize the part of that vehi-
cle which is closest to you.
• There is a fence or wall, etc., with a uniform pattern (striped
pattern, brick, etc.) or with no
pattern in front.

ment is required. Have the sensor
adjusted at a Toyota dealer.)
• When a large amount of snow or ice sticks to the rear bumper sur-
face around the radar sensors
• When the vehicle is driven on a snow-covered road or in an envi-
ronment in which there are no
objects around (such as in a des-
ert) for a prolonged period of time
• When the temperature around the
radar sensors increases exces-
sively due to long driving on uphill
grades in the summer, etc.
• When the temperature around the radar sensors becomes extremely
low
• When the vehicle battery voltage lowers
• When the vehicle voltage exceeds
the battery voltage rating
●The BSD/RCTA will resume oper-
ation once these conditions are
corrected, and the BSD/RCTA
OFF indicator will disappear. How-
ever, if the BSD/RCTA OFF indi- cator appears for a prolonged
period of time, have the system
inspected at a Toyota dealer as
soon as possible.
●The detectability o
f the radar sen-
sors is restricted. The BSD/RCTA
detection may be impaired and
the system may not operate prop-
erly under the following condi-
tions.
• When the rear bumper around the
radar sensors is distorted
• When ice, snow or mud adheres to the rear bumper surface around
the radar sensors
• When stickers, etc . are affixed on
the areas of the radar sensors on
the rear bumper
• During adverse weather condi- tions such as ra in, snow or fog
• When driving on wet roads such as snow-covered roads and
through puddles
●The radar sensors may not detect
or may have difficulty detecting
the following vehicles and objects.
• Small motorcycles, bicycles, pedestrians, stationary objects on
the road or ro ad side, etc.
• Vehicles with body shapes that the radar may not reflect (vehicles
with lower body height such as a
trailer with no cargo and sports
cars)
• Vehicles that are not approaching
your vehicle even though they are
in the detection area (either on a
neighboring lane to the rear or
beside your vehicle when revers-
ing) (The system determines the
presence of approaching vehicles
based on data detected by the
radar sensors.)
• Vehicles traveling at significantly
different speeds
• Vehicles driving in parallel at almost the same speed as your
vehicle for a prolonged time
• Oncoming vehicles
• Vehicles in a lane beyond the neighboring lane
• Vehicles travelling at a signifi- cantly lower speed that you are
