■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

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.
