2584-5. Using the driving support systems
■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. 342, 349).
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.

WARNING
●The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of
your vehicle
● The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sen sor.
• There will be a short delay between obstacle detection and dis play.
Even at slow speeds, there is a possibility that the obstacle w ill come
within the sensor’s detection areas before the display is shown and the
warning beep sounds.
• Thin posts or objects lower than the sensor may not be detecte d for col-
lision when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or
air flow noise of air conditioning system.
