The Intuitive parking assist is a warning
system used when parking the vehicle
at low speed (e.g. into a garage). It uses
an ultrasonic sensor, which checks the
approximate distance to an obstacle. It
will inform you of the approximate dis-
tance to an obstacle by displaying in-
formation on the multi−information dis-
play and the screen, and with beeping
sounds.
1Front corner sensors
There is one of these installed on each cor-
ner of the front bumper, they inspect ob-
stacles and will sound a warning depend-
ing on the distance to the obstacle. (See
“ — Front corner sensors” on page 284.)
2Rear corner sensors
There is one of these installed on each cor-
ner of the rear bumper, they inspect ob-
stacles and will sound a warning depend-
ing on the distance to the obstacle. (See
“ — Rear corner sensors” on page 285.)
3Back sensors
There are two of these installed near the
center of the rear bumper, they inspect ob-
stacles and will sound a warning depend-
ing on the distance to the obstacle. (See
“ — Back sensors” on page 286.)
To use the Intuitive parking assist, with
the “ENGINE START STOP” switch in
IGNITION ON mode, push the Intuitive
parking assist button. Pushing the In-
tuitive parking assist button again will
turn the Intuitive parking assist off.
When ON, an indicator on the switch
comes on to inform the driver that the func-
tion is operational.
The Intuitive parking assist will remain on
even after turning the “ENGINE START
STOP” switch to “OFF” and then to IGNI-
TION ON mode with the main switch on.
However, a beep does not sound at this
time.
If an error is detected in the Intuitive park-
ing 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 fail-
ure warning” on page 289.

(See “ — Rear view monitor dis-
play” on page 291.)
When an obstacle is detected, the indi-
cator bars will come on or flash, accom-
panied by beeping. How many bars are
lit or flashing depends on the distance
to the obstacle.
When the obstacle is not detected any lon-
ger, beeps will stop sounding and the mul-
ti−information display and the screen will
return to the previous display.
The volume of the beeps and the display
on the screen can be changed. See “ —
Setting the Intuitive parking assist” on
page 293.
1Detection by front corner sen-
sors
2Detection by rear corner sensors
3Detection by back sensors
The approximate distance to the obstacle
is shown with up to 4 bars on the rear of the
vehicle and up to 3 bars on the front cor-
ners and the rear corners of the vehicle.
CAUTION
To avoid an accident or injury, ob-
serve the following instructions, and
then drive slowly using the brakes
while visually confirming a safe dis-
tance around your vehicle.
The sensor detection range is limit-
ed around the bumper. Be sure to
visually confirm safety outside the
sensor detection. For the sensor
detection range, see “ — Detection
range of sensors” on page 288.
It might take time for the sensors to
detect obstacles.
Depending on the shape of the ob-
stacle, indicators or beeps may not
warn you properly, and the detec-
tion range may also be shortened.
It might be difficult to hear beeps
due to the volume of audio or air
flow noise of the air conditioning.

The front corner sensor only operates
when the vehicle speed is less than
about 6 mph (10 km/h). It checks the
approximate distance to obstacles at
an angle to the front of the vehicle, and
sounds a warning depending on the
distance. This sensor does not operate
if the transmission is in “P” position.Multi−information display:
The indicator bars come on depending on
the distance to the obstacle and flash
when the distance between the vehicle
and the obstacle is less than about 0.8 ft.
(25 cm).
Touch screen:
When an obstacle is detected, indicator
bars illuminate in yellow. The number of
the indicator bars reduces as the vehicle
gets closer to the obstacle, and turn red
when the distance between the vehicle
and obstacle is less than 0.8 ft. (25 cm).
Beeps:
As distance to the obstacle gets closer, the
interval of the intermittent sound gets
shorter, and then finally changes to a con-
tinuous sound when the distance between
the vehicle and the obstacle is less than
about 0.8 ft. (25 cm).
CAUTION
When you move your vehicle, be sure
to visually confirm a safe distance
around your vehicle and drive slowly,
or an accident or injury may result.

When obstacles are detected on the
front and rear of the vehicle at the same
time; the multi−information display and
screen illuminate their relevant indica-
tor 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 illustra-
tion 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.
2The 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 ob-
stacle is high as shown, the Intuitive park-
ing assist warns the driver by continuous
beeping (repeating 7 intermittent beeps
and one longer beep as one cycle).
3Both 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 ob-
stacles is very high as shown, the Intuitive
parking assist warns the driver by continu-
ous beeping (repeating 3 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 the air conditioning. To
avoid an accident or injury, drive
slowly using the brakes while visual-
ly confirming a safe distance around
your vehicle.

The sensor detection range is limited
around the bumper. Be sure to confirm
a safe distance around your vehicle and
drive slowly.
The range of the sensors may change de-
pending on the shape of the object etc..The Intuitive parking assist may not
work properly in the following cases:
When the bumper is damaged.
When the part near the sensors is sub-
jected 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 Intuitive parking assist
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 dis-
play appears and the Intuitive parking
assist 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, motor-
cycle engine, air braking sound from
heavy−duty vehicles.

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 ve-
hicle.
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 de-
tected, 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 de-
tect 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 project-
ed
Shorter objects
CAUTION
Do not install accessories within the
sensors’ detection areas, as this may
cause the Lexus parking assist−sen-
sor to function incorrectly, possibly
leading to an accident.
If an error is detected when the Intuitive
parking assist is turned on, the vehicle
symbol comes on or flashes with beep-
ing sounds.
However, the sensors functioning properly
continue their obstacle detection.
