parts are extremely cold, extremely hot,
or wet
• If the vehicle is not properly maintained (brakes or tires are excessively worn,
improper tire inflation pressure, etc.)

pear and the system will become opera-
tional when normal operating conditions
return:
• When the radar sensor or camera sensor or the area around either sensor is hot,
such as in the sun
