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 follo
wing obstacle distan ces 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 f
t. (35 cm).
●If obstacles are detected by the dual sensors in 2 places at once, or if
both rear corner sensors detect obst acles at the same time, the system
will sound a warning beep for the closer of the 2 obstacles.
● If multiple obstacles ar
e detected in front and behind th e vehicle at the
same time, the warning beep will change in the following manner:
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected near a different area of th e vehicle, the warning beep will sound
6 beeps then one continuous beep.
• If an obstacle has been detected within 0
.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected within 0.8 ft. (25 cm) of a different area of the vehicle, the warn -
ing beeps will sound 2 beeps then one continuous beep
.
●You can change the volume of the warning beeps. ( P. 1 5 0 )

The detection area of the sensors is
shown to the left.
If obstacles move too close to the
sensors, they
will not be detected. 
If the malfunction screen is dis -
played, the dual sensor detection

If there is snow or mud on a sensor
Multi-information display
Touch screen
The same symbol will appear on the insert display.
The location of the affected sensor is displayed. Wipe off whatever is
stuck to the sensor. (The above illustration shows something on the left
front sensor.) 
If the “CLEAN SONAR” message is di splay
ed even though the sensor is
not dirty or you have already cleaned it, there is most likely a sensor mal -
function. Have the vehicle ch eck
ed by your Lexus dealer.

If the steering neutral position is unknown
After the battery has been reconnected, the steering sensor will need to
be initialized. At this time, if the dual sensors detect an obstacle, the steer -
ing guide symbol and both arr
ows will be displayed.
Multi-information display
Touch screen
Use one of the following methods to initialize the steering sensor.
• With the vehicle stopped, turn the s teering wheel all the w
ay to the left,
then the right. (The order is not important.)
• Drive for more than 5 minutes on an un-cr
owded road with as few
curves and corners as possible.
If the steering guide symbol disappe ars, the steering sensor has been ini-
tialized. If the steering guide symbol does not disappear
, have the vehicle
checked by your Lexus dealer.
