 Handling the radar sensor
Observe the following to ensure the pre-crash safety system can function
effectively:
 Keep the sensor and front grille clean at all times.
Clean the sensor and front grille with a soft cloth so you do not mark or
damage them.
 Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may become
inaccurate or malfunction. If the sensor or surrounding area is subject to a
strong impact, always have the area inspected and adjusted by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
 Do not disassemble the sensor.
 Do not attach accessories or stickers to the sensor, grille or surrounding
area.
 Do not modify or paint the sensor and grille cover.
