■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 any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
SituationActions
When the area around a sensor
is covered with dirt, moisture
(fogged up, covered with con-
densation, ice, etc.), or other
foreign matterTo clean the part of the windshield in front
of the front camera, use the windshield
wipers or the windshield defogger of the
air conditioning system (P. 577).
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.
