■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfunction in the
system.
- In the following situations, perform the actions specified in the 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.
- In the following situations, if the situation has changed (or the vehicle
has been driven for some time) and 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.
- When the temperature around the radar sensor is outside of the operational
range, such as when the vehicle is in the sun or in an extremely cold environment
- When the front camera cannot detect objects in front of the vehicle, such
as when driving in the dark, snow, or fog, or when bright lights are shining
into the front camera
The pre-collision system uses a radar sensor and front camera to detect objects
(®P.206) in front of the vehicle. When the system determines that the possibility
of a frontal collision with an object is high, a warning operates to urge the driver
to take evasive action and the potential brake pressure is increased to help the
driver avoid the collision...

The Blind Spot Monitor is a system that uses rear side radar sensors installed
on the inner side of the rear bumper on the left and right side to assist the driver
in confirming safety when changing lanes.
