1Dual sensors
There are four of these steering guidance sensors installed in
the front bumper.
Steering guidance means that when an obstacle is inspected,
not only is the distance estimated, this function judges whether
collision with the obstacle within detection range is avoidable
if the vehicle is steered in a certain direction, and informs the
driver. There will be no warning if it judges that there is no
possibility of collision with the obstacle within detection range.
(See page 369.)
2 Rear corner sensors
There is one of these installed on each corner of the rear
bumper, they inspect obstacles and will sound a warning
depending on the distance to the obstacle. (See page 373.)
3 Back sensors
There are two of these installed near the center of the rear
bumper, they inspect obstacles and will sound a warning
depending on the distance to the obstacle. (See page 374.)

To use the intuitive parking assist, push the main switch
in the switch box with the engine switch in “IG ON” mode.
Pushing the main switch again will turn the intuitive
parking assist off.
When you push the main switch, the indicator light in the
instrument cluster comes on and a beep sounds for one
second, indicating that the intuitive parking assist is turned on.
The intuitive parking assist will remain on even after turning the
engine switch to “OFF” and then to “IG−ON” mode with the
main switch on. However, a beep does not sound at this time.
If an error is detected in the intuitive parking assist while
self−checking, beeps sound and a warning appears in the
multi−information display and on the screen. For details, see
“Intuitive parking assist failure warning” on page 378.

(A) Collision will be unavoidable: Collision with the
detected obstacle cannot be avoided even by changing the
steering.
(B) Collision will be avoided by changing the steering:
Collision with the obstacle can be avoided by changing the
steering.
(C) Collision will be avoide d with the present steering
angle: Even if you continue moving at the present steering
angle, the distance to the obstacle within sensor detection
range will not be less than about 25 cm (0.8 ft.).
The dual sensors detect an obstacle in front of the vehicle
or at an angle to the front of the vehicle, and estimate the
distance to the obstacle and also the steering angle
required. They will evaluate which of the above 3
conditions is applicable. The selector lever must be in any position other than “P” or “R”
for these sensors to operate, however the obstacle at an angle
to the front of the vehicle will also be detected while the selector
lever is in “R”.
CAUTION
With long obstacles such as walls, the decision of the
sensor may change as the obstacle gets closer; from
certain avoidance to avoidance if steering is changed;
from certain avoidance to unavoidable collision; and
there are also times when the
decision will be changed
from avoidance if steering is changed, to certain
collision. When you move your vehicle, be sure to
confirm a safe distance around your vehicle with your
eyes and drive slowly, or an accident or injury may
result.
The steering guidance may not operate properly in the
following conditions:
Tires other than those of Lexus genuine size are
installed.
The steering sensor information cannot be received
properly. (See “Intuitive parking assist failure warning”
on page 378.)

NOTE:
* The detection range can be changed from about 50 cm
(1.5 ft.) for dual sensors and about 60 cm (2 ft.) for back
sensors.
Ask your Lexus dealer for details.
The intuitive parking assist may not work properly in the
following cases:
When the bumper is damaged.
When the part near the sensors is subjected to a strong
impact.
When an accessory is installed within the sensor detection
range.
When snowflakes or mud gets on the sensors.
(If removed, the system will work properly.)
When water is splashed from a high pressure car wash or
steam on the sensors.
When a sensor is covered with your hand.
When the vehicle is tilted.
In extreme hot or cold weather
(In extreme cold weather, the error display appears and the
system becomes inoperative.)
When driving on bumpy roads, slopes, gravelled roads or
grass.
Devices issuing ultrasonic waves are operated around your
vehicle, such as a horn from another vehicle, motorcycle
engine, air braking sound from heavy −duty vehicles.
When another vehicle equipped with ultrasonic sensors
gets close to your vehicle.
When heavy rain or water is splashed over the vehicle.
(Drive carefully as the braking distance may be affected.)
When a radio antenna or fender pole is mounted on your
vehicle.
If towing eyelet is installed on your vehicle.
When you are driving towards a tall curb stone or curb stone
having right angle.
The detection range for an object such as a traffic sign may
be shortened.
An object just under the bumper cannot be detected.
Although an object lower than the location of sensors is
once detected, the detection might be stopped when your
vehicle gets closer to the object.
When an obstacle is very close to the sensors.

Thin objects such as wire or rope
Sound wave absorbing objects such as cotton or snow
Objects with a sharp edge
Tall objects with the upper part projected
Shorter objects
Intuitive parking assist failure warning
If an error is detected when the intuitive parking assist is
turned on, the vehicle symbol comes on or flashes with
beeping sounds.
At this time steering guidance is temporarily stopped.
However, the sensors functioning properly continue their
obstacle detection. For details, see “When the detection range
of the sensors is shorter” on page 381.
The intuitive parking assist failure warning display is not given
in either of the following operations:
Changing to another screen
Turning off the main switch for the intuitive parking assist
