WARNING
■Front camera installation area on the windshield
If the system determines that the windshield may be fogged up, it will automatically operate the heater to
defog the part of the windshield around the front camera. When clean-ing, etc., be careful not to touch the
area around the front camera until the windshield has cooled sufficiently, as touching it may cause burns.
■Precautions for the driver moni-tor camera (if equipped)
Observe the following precautions. Failure to do so may lead to malfunc-tion of the driver monitor camera and
the systems not operating properly, possibly leading to an accident result-ing in death or serious injury.
●Do not subject the driver monitor camera or its surrounding area to
strong impact.
If subjected to a strong impact, the
driver monitor camera may move out
of alignment and the driver may no
longer be detected correctly. In this
case, have the vehicle inspected by
any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
●Do not disassemble or modify the driver monitor camera.
●Do not attach accessories, stickers (including transparent stickers), etc. to the driver monitor camera or its
surrounding area.

■Detection of detectable objects
Objects are detected based on their size, shape, and movement.Depending
on the ambient brightness, movement, posture and direction of a detectable object, it may not be detected and the
system may not operate properly. The system detects shapes, such as the fol-lowing, as detectable objects.

Driving
Constant speed cruising:
When there are no vehicles ahead
The vehicle drives at the speed set by the driver.
If the set vehicle speed is exceeded while driving down a hill, the set vehicle speed
display will blink and a buzzer will sound.
Deceleration and follow-up cruising
When a preceding vehicle driving slower than the set vehicle sp eed is
detected
When a vehicle is detected driving ahead of your vehicle, the v ehicle automatically
decelerates and if a greater reduction in vehicle speed is nece ssary, the brakes are
applied (the stop lights will come on at this time). The vehicl e is controlled to main-
tain the vehicle-to-vehicle distance set by the driver, in acco rdance with changes in
the speed of the preceding vehicle. If vehicle deceleration is not sufficient and the
vehicle approaches the vehicle ahead, the approach warning will sound.
Acceleration
When there are no longer any preceding vehicles driving slower than the
set vehicle speed
The vehicle accelerates until the set vehicle speed is reached and then resumes
constant speed cruising.
Starting off: If a preceding vehicle stops, the vehicle will al so stop (con-
trolled stop). After the preceding vehicle starts off, pressing the “RES”
switch or depressing the accelerator pedal will resume follow-u p cruising
(start off operation). If a start off operation is not performe d, the con-

functions of the system cannot oper-
ate: P. 2 8 1
■LTA control when operation is can- celed
When emergency driving stop system
operation is canceled, LTA control may also be canceled.
If driving operations are not
detected after the hands off steer-
ing wheel warning operates, a
buzzer will sound intermittently and
a message will be displayed to
warn the driver, and the system will
judge if the driver is responsive or
not. If driving operations, such as
holding the steering wheel, are not
performed within a certain amount
of time, the system will enter warn-
ing phase 2.
Vehicles with a driver monitor cam-
era: Depending on the type of
detection of the driver’s unrespon-
siveness, the system may skip
warning phase 1 and start the con-
trol of warning phase 2.
After entering warning phase 2, a
buzzer will sound in short intervals
and a message will be displayed to
warn the driver, and the vehicle will
slowly decelerate. If driving opera-
tions, such as holding the steering
wheel, are not performed within a
certain amount of time, the system
will determine that the driver is not
responsive and enter the decelera-
tion stop phase.
The audio system will be muted until
the driver becomes responsive.
When the vehicle is decelerating, the
brake lights may illuminate, depending
on the road conditions, etc.
After the vehicle has decelerated a cer-
tain amount, the emergency flashers
(hazard lights) will flash.
After the driver is judged as being
not responsive, a buzzer will sound
continuously and a message will be
displayed to warn the driver, and
the vehicle will slowly decelerate
and stop. While the vehicle is
decelerating, the emergency flash-
ers (hazard lights) will flash to warn
other drivers of the emergency.
After the vehicle is stopped, the
parking brake will be applied auto-
matically. After entering the stop
and hold phase, the buzzer will
continue sounding continuously, the
emergency flashers (hazard lights)
will flash to warn other drivers of
the emergency, and the doors will
unlock.

WARNING
■Cautions regarding the use of
the system
There is a limit to the degree of recog- nition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The driver is always responsible for paying
attention to the vehicle’s surroundings and driving safely.
■To ensure the system can oper-ate properly
Observe the following precautions.
Failing to do so may result in the vehi- cle being unable to be driven safely and possibly cause an accident.
●Do not damage the sensors, and always keep them clean.
●Do not attach a sticker or install an electronic component, such as a backlit license plate (especially fluo-
rescent type), fog lights, fender pole or wireless antenna near a radar sensor.
●Do not subject the surrounding area of the sensor to a strong impact. If
subjected to an impact, have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer. If the front or rear bumper needs to be removed/installed or replaced,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do n ot m od i fy, d is a sse mb l e o r p ai n t the sensors.
●Do not attach a license plate cover.
●Keep your tires properly inflated.
■When to disable the function
In the following situations, disable the function as it may operate even though there is no possibility of a colli-
sion.
●Failing to observe the warnings
above.
●A non-genuine Toyota suspension
(lowered suspension, etc.) is installed.
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
●When using a high pressure washer to wash the vehicle, do not spray the sensors directly, as doing
so may cause a sensor to malfunc- tion.

umbrella • Pedestrians which are obscured by darkness, such as at night
●In some situations, such as the follow-ing, pedestrians may not be detected
by the rear camera detection function, preventing the function from operating properly:
• When backing up in inclement weather (rain, snow, fog, etc.)• When the rear camera is obscured
(dirt, snow, ice, etc., are attached) or scratched• When a very bright light, such as the
sun, or the headlights of another vehi- cle, shines directly into the rear cam-era
• When backing up in a place where the surrounding brightness changes sud-denly, such as at the entrance or exit

• If an electronic component, such as a backlit license plate or rear fog light, is installed near the rear camera
• If a bumper protector, such as an additional trim strip, is installed to the rear bumper
■Situations in which the system may
operate unexpectedly
●Even though there are no pedestrians
in the detection area, some objects,
such as the following, may be detected, possibly causing the rear camera detection function to operate.
• Three dimensional objects, such as a pole, traffic cone, fence, or parked vehicle
• Moving objects, such as a car or motorcycle• Objects moving toward your vehicle
when backing up, such as flags or puddles (or airborne matter, such as smoke, steam, rain, or snow)
• Cobblestone or gravel roads, tram rails, road repairs, white lines, pedes-trian crossings or fallen leaves on the
road • Metal covers (gratings), such as those used for drainage ditches
• Objects reflected in a puddle or on a wet road surface• Shadows on the road
●In some situations, such as the follow-ing, the rear camera detection func-
tion may operate even though there are no pedestrians in the detection area.
• When backing up toward the roadside or a bump on the road• When backing up toward an
incline/decline • If the rear of the vehicle is raised or lowered due to the carried load
• If a bumper protector, such as an additional trim strip, is installed to the rear bumper
• If the orientation of the rear camera has been changed• If a towing eyelet is installed to the
rear of the vehicle • When water is flowing over the rear camera lens
