Steering guide symbol
Displays the steering maneuvers required to avoid an obstacle. Move the
steering wheel in the direction shown by the arrow.
Beeps and obstacle distance
A beep sounds when an obstacle with which there is a danger of collision
is detected. As the vehicle moves closer to the obstacle, the interval of
the beep becomes shorter.
● When the following obstacle distances are reached, the beep changes
from intermittent to continuous:
• If the distance to the obstacle detected by the dual sensors or rear corner
sensors is less than 0.8 ft. (25 cm).
• If the distance to the obstacle detected by the back sensors is less than 1.1
ft. (35 cm).
● If obstacles are detected by the dual sensors in 2 places at once, or if
both rear corner sensors detect obstacles at the same time, the system
will sound a warning beep for the closer of the 2 obstacles.
2-4. Using other driving systems
