■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.

SituationActions
When the area around a cam-
era is covered with dirt, mois-
ture (fogged up, covered with
condensation, ice, etc.), or
other foreign matter
Using the wiper and A/C function,
remove the dirt and other attached mat-
ter. (P. 527)
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 vehi-
cle was parked, depending on its type,
the sunlight reflected from the surface
of the sunshade may cause the tem-
perature 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
system 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 displayed.Check whether there is attached materi-
als on the radar sensor and radar sensor
cover, and if there is, remove it.

Driving
●In the following situations, if the situation has changed (or the vehicle has

detected, the message will disappear and the system will become opera-
tional.
If the message does not disappear, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
• When the temperature around the radar sensor is outside of the opera-
tional 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
• Depending on the conditions in the vicinity of the vehicle, the radar may
judge the surrounding environment can not be properly recognized. In
that case, “Pre-Collision System Unavailable” is displayed.

PCS (Pre-Collision System)
The system can detect the following:
●Ve hi cl e s
●Bicyclists
●Pedestrians
The pre-collision system uses a radar sensor and front camera
to detect objects (P. 368) in front of the vehicle. When the sys-
tem determines that the possibility of a frontal collision with an
object is high, a warning operates to urge the driver to take eva-
sive action and the potential brake pressure is increased to help
the driver avoid the collision. If the system determines that the
possibility of a frontal collision with an object is extremely high,
the brakes are automatically applied to help avoid the collision
or help reduce the impact of the collision.
The pre-collision system can be disabled/enabled and the warning
timing can be changed. (P. 372)
