• 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

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 environment

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 tem-
perature around the front camera.
If a sunshade was used when the vehicle 
was parked, depending on its type, the sun-
light reflected from the surface of the sun-
shade 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 envi-
ronment, 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 Radar In Self 
Calibration Unavailable See Owner’s Man-
ual” is displayed.

Check whether there is attached materials 
on the radar sensor and radar sensor cover, 
and if there is, remove it.
