Observe the following to ensure the pre-collision system can function effec-
tively.

damage them.

If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by your Toyota dealer.

l Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.

observe your surroundings and checking for any obstacles or other road
hazards.
