When driving
Intuitive parking assist (if equipped)
Intuitive parking assist uses sensors in the front and rear of the vehicle to
detect the distance between the vehicle and any obstacles, and informs the
driver of this distance using the mult i-information display, the touch screen,
and warning beeps.

The system may be used at speeds less than about 6 mph (10 km/h).
■ Sensor types
Dual sensors
There are 4 sensors installed in the front bumper, two in the center section
to detect obstacles directly ahead, an d one in each corner of the bumper,
to detect obstacles in those areas. 
The dual sensors detect obstacles ahea d of the v
ehicle, and judge whether
avoidance maneuvers are necessary (whether the obstacle will come
within 0.8 ft. (25 cm) of the vehicle), according to the distance between
the obstacle and the vehicle, and the steering wheel position. The screen
display and beeps will change accordingly.
Rear corner sensors
These sensors detect obstacles around the rear corners of the vehicle.
Back sensors
These sensors detect obstacles behind the vehicle.

Multi-information display and touch screen
If the sensors detect an obstacle, it is displayed on the multi-information
display in the instrument cluster. 
You can change the conditions under which informa tion is display
ed on
the touch screen. ( P. 1 5 3 )

Display distance and beeps
When the intuitive parking assist is activated, the approximate distance to
the obstacle is displayed. Also, if an obstacle with which a collision is pos -
sible is detected, a warning beep will sound.

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 checked by your Lexus dealer.
