Handling the radar sensor
Observe the following to ensure the pre-collision system can function effec-
tively:
●
Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover 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 your Toy-
ota dealer.
●
Do not disassemble the sensor.
●
Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
●
Do not modify or paint the sensor and grille cover.
