WARNING
■When to disable the pre-collision system
In the following situations, disable the system, as it may not operate prop-
erly, possibly leading to an accident resulting in death or serious injury:
● When the vehicle is being towed
● When your vehicle is towing another vehicle
● When transporting the vehicle via truck, boat, train or similar means of
transportation
● When the vehicle is raised on a lift with the engine running and the tires
are allowed to rotate freely
● When inspecting the vehicle using a drum tester such as a chass is dyna-
mometer or speedometer tester, or when using an on vehicle whee l bal-
ancer
● When a strong impact is applied to the front bumper or front gr ille, due to
an accident or other reasons
● If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning
● When the vehicle is driven in a sporty manner or off-road
● When the tires are not properly inflated
● When the tires are very worn
● When tires of a size other than specified are installed

sandstorm
• When the vehicle is hit by water, snow, dust, etc., from a vehicle ahead
• When driving through steam or smoke
• When driving in a place where the surrounding brightness changes sud- denly, such as at the entrance or exit of a tunnel
• When a very bright light, such as the sun or the headlights of oncoming
traffic, shines directly into the front camera
• When the surrounding area is dim, such as at dawn or dusk, or while at
night or in a tunnel
• After the engine has started the vehicle has not been driven for a certain amount of time
• While making a left/right turn and for a few seconds after mak ing a left/
right turn
• While driving on a curve and for a few seconds after driving o n a curve

• If the wheels are misaligned
• If a wiper blade is blocking the front camera
• The vehicle is wobbling.
• The vehicle is being driven at extremely high speeds.
• When driving on a hill
• If the radar sensor or front camera is misaligned • If the front of the vehicle is raised or
lowered

Press the LDA switch to turn the
LDA system on.
The LDA indicator illuminates and
a message is displayed on the
multi-information display.
Press the LDA switch again to turn
the LDA system off.
When the LDA system is turned on
or off, operation of the LDA system
continues in the same condition
the next time the engine is started.
WARNING
■Preventing LDA system malfunctions and operations performed by
mistake
● Do not modify the headlights or place stickers, etc., on the su rface of the
lights.
● Do not modify the suspension, etc. If the suspension, etc., needs to be
replaced, contact your Toyota dealer.
● Do not install or place anything on the hood or grille. Also, d o not install a
grille guard (bull bars, kangaroo bar, etc.).
● If your windshield needs repairs, contact your Toyota dealer.

The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.
■The system can be operated when
●The engine switch is in ON mode.
● Intuitive parking assist function is on.
● The vehicle speed is less than about 6 mph (10 km/h).
● A shift position other than P is selected.
■ Sensor detection information
●The sensor’s detection areas are limited to the areas around th e vehicle’
front and rear bumpers.
● The following situations may occur during use.
• Depending on the shape of the object and other factors, the de tection dis-
tance may shorten, or detection may be impossible.
• Detection may be impossible if static objects draw too close to the sen- sor.
• There will be a short delay between static object detection an d display
(warning buzzer sounds). Even at low speeds, there is a possibi lity that
the object will come within 11.9 in. (30 cm) before the display is shown
and the warning buzzer sounds.
• It might be difficult to hear the buzzer due to the volume of the audio sys- tem or air flow noise of the air conditioning system.
• It may be difficult to hear the sound of this system due to the buzzers of
other systems.

Objects which the system may not be properly detected
The shape of the object may prevent the sensor from detecting it. Pay partic-
ular attention to the following objects:
●Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low objects
● Tall objects with upper sections projecting outwards in the dir ection of your
vehicle
■ Situations in which the syst em may not operate properly
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect objects. Particular instances where this
may occur are listed below.
● There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
● A sensor is frozen. (Thawing t he area will resolve this problem .)
In especially cold weather, if a sensor is frozen the sensor di splay may be
displayed abnormally, or objects, such as a wall, may not be detected.
● On an extremely bumpy road, on an incline, on gravel, or on grass.
● When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
● A sensor is coated with a sheet of spray or heavy rain.
● If objects draw too close to the sensor.
● When a pedestrian is wearing clothing that does not reflect ult rasonic waves
(ex. skirts with gathers or frills).
● When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the d etection range.
● Strong wind is blowing
● When driving in inclement weather such as fog, snow or a sandst orm
● When an object that cannot be detected is between the vehicle a nd a
detected object
● If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front
of the vehicle or runs out from the side of the vehicle
●
When a sensor or the area around a
sensor is extremely hot or cold.
