• 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 brig ht lights are shining into the front camera
• Depending on the conditions in the vicinity of the vehicle, the radar may judge the sur-
rounding environment can not be properly re cognized. In that case, “Pre-Collision Sys-
SituationActions
When the area around a camera is covered
with dirt, moisture (fogged up, covered with
condensation, ice, etc. ), or other foreign
matterUsing the wiper and A/C function, remove
the dirt and other attached matter.
(  P.245)
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 Sy stem Radar In Self
Calibration Unavailable See Owner’s Man-
ual” is displayed.Check whether there is attached materials
