Driving
■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfu nction in
the system.
● In the following situations, perform the actions specified in t he table. When
the normal operating conditions are detected, the message will disappear
and the system will become operational.
If the message does not disappear, contact your Toyota dealer.
SituationActions
When the area around a camera
is covered with dirt, moisture
(fogged up, covered with con-
densation, ice, etc.), or other for-
eign matter
Using the wiper and A/C function, remove
the dirt and other attached matter
( P. 340, 347).
When the temperature around
the front camera is outside of
the operational range, such as
when the vehicle is in the sun or
in an extremely cold environ-
ment
If the front camera is hot, such as after the
vehicle had been parked in the sun, use
the air conditioning system to decrease
the temperature around the front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the
sunlight reflected from the surface of the
sunshade may cause the temperature of
the front camera to become excessively
high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold
environment, use the air conditioning sys-
tem to increase the temperature around
the front camera.
The area in front of the front
camera is obstructed, such as
when the hood is open or a
sticker is attached to the part of
the windshield in front of the
front camera.
Close the hood, remove the sticker, etc. to
clear the obstruction.
When “Pre-Collision System
Unavailable” is displayedCheck whether there is attached materi-
als on the radar sensor and radar sensor
cover, and if there is, remove it.

Driving
■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 and 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 i t. 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 the 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.

3024-5. Using the driving support systems
●When there are spinning objects near your vehicle such as the f an of an air
conditioning unit
● When water is splashed or sprayed toward the rear bumper, such as from a
sprinkler
● Moving objects (flags, exhaust fumes, large rain droplets or sn owflakes, rain
water on the road surface, etc.)
● When the distance between your vehicle and a guardrail, wall, etc., that
enters the detection area is short
● Gratings and gutters
● When a sensor or the area around a sensor is extremely hot or c old
● If the suspension has been modified or tires of a size other th an specified
are installed
● If the front of the vehicle is raised or lowered due to the car ried load
●
When a detected vehicle turns while
approaching the vehicle
