1Multiinformation display:
The indicator bars will come on depending on the
distance to the obstacle and will flash when the distance
between the vehicle and the obstacle is less than about
25 cm (0.8 ft.).
2 Screen:
The indicator bars will come on in yellow according to the
distance to the obstacle. When the distance between the
vehicle and the obstacle is less than about 25 cm (0.8 ft.),
the yellow indicator bars will turn red. In addition, the
current direction of the tires is also indicated in 3 stages.
Beeps:
As distance to the obstacle gets closer, the interval of the
intermittent sound gets shorter, and then finally to a continuous
sound when the distance between the vehicle and the obstacle
is less than about 25 cm (0.8 ft.). (B) Collision will be avoided by changing the steering

5About 25 cm (0.8 ft.) to about 37.5 cm (1.1 ft.)
The steering guide symbol and the arrow indicating which
direction should be steered appear along with the bar
indicators and beeps.

STARTING AND DRIVING
378The above illustration indicates that the collision will be
avoided by turning the steering wheel clockwise.
When
the possibility that the distance between the vehicle and
the obstacle is less than about 25 cm (0.8 ft.) is eliminated by
turning the steering wheel more, the steering guide symbol will
go out and the beeps will stop sounding.
The steering guide symbol and arrow are not instructions
you must observe. They are just a guide to avoid a
collision.
1 Multiinformation display:
The indicator bars will come on depending on the
distance to the obstacle . The steering guide symbol and
arrow will also come on.
2Screen:
The indicator bars will come on in yellow depending on
the distance to the obstacle. The steering guide symbol
and arrow will also come on. In addition, the current
direction of the tires is also indicated in 3 stages.
Beeps:
As distance to the obstacle gets closer, the interval of the
intermittent sound gets shorter, and then finally to a continuous
sound when the distance between the vehicle and the obstacle
is less than about 25 cm (0.8 ft.).
CAUTION
When an obstacle is detected within about 25 cm (0.8 ft.)
from the vehicle, the dual sensors will change the
determination to an unavoidable collision. To avoid an
accident or injury, be sure to confirm a safe distance
around your vehicle with your eyes and drive slowly.

The indicator bars will come on in green depending on the
distance to the obstacle. In addition, the current direction
of the tires is also indicated in 3 stages.
Beeps:
Beeps will not sound.
CAUTION
To avoid an accident or injury, observe the following.
When you move your vehicle, be sure to confirm a safe
distance around your vehicle with your eyes and drive
slowly.
 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 an obstacle is detected within about 25 cm (0.8
ft.) from the vehicle, the dual sensors will change the
determination to an unavoidable collision.

Rear corner sensors

4About 25 cm (0.8 ft.) to about 37.5 cm (1.1 ft.)
5Less than about 25 cm (0.8 ft.) The rear corner sensor only operates when the
transmission is in “R”, it checks the approximate distance
to obstacles at an angle to the rear of the vehicle, and
sounds a warning depending on the distance.

in “R”, it checks the approximate distance to obstacles
close to the rear of the vehicle, and sounds a warning
depending on the distance.

Numerous obstacles are detected on the front
and rear of the vehicle simultaneously
G31060
When obstacles are detected on the front and rear of the
vehicle at the same time; the multiinformation display
and screen illuminate their relevant indicator bars. And
beeps are as follows:
1Obstacles detected on the front and rear of the
vehicle are not in areas where continuous beeping
should sound: The warning for the obstacle closer to the vehicle will be
issued.
The above illustration indicates the obstacle detected
by the back sensors is closer to the vehicle. So, the warning for
the obstacle detected by the back sensors will be given.
2 The obstacle detected on the front or rear of the
vehicle is in an area where continuous beeping
should sound:
If the possibility of collision with the obstacle is high as shown,
the system warns the driver by continuous beeping (repeating
6 intermittent beeps and one longer beep as one cycle).
3 Both obstacles detected on the front and rear of the
vehicle are in areas where continuous beeping
should sound:
If the possibility of collision with the obstacles is very high as
shown, the system warns the driver by continuous beeping
(repeating 2 quick beeps and one longer beep as one cycle).
CAUTION
It might be difficult to hear beeps due to the volume of
audio or air flow noise of air conditioning. To avoid an
accident or injury, drive slowly using the brakes while
confirming a safe distance around your vehicle with
your eyes.

Detection range of sensors*
G31061
 1About 3 m (10 ft.) 2About 1 m (3 ft.)
3About 1m 50 cm (5 ft.) 4About 50 cm (1.5 ft.)
The sensor detection range is limited around the bumper.
Be sure to confirm a safe distance around your vehicle
and drive slowly. 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.

STARTING AND DRIVING

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. The intuitive parking assist may not detect the following:

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
