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 Lexus parking assist −sensor”
on page 289.

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.
DThe 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 284.
DIt might take time for the sensors to
detect obstacles.
DDepending on the shape of the ob-
stacle, indicators or beeps may not
warn you properly, and the detec-
tion range may also be shortened.
DIt might be difficult to hear beeps
due to the volume of audio or air
flow noise of the air conditioning.

1About 1.1 ft. (37.5 cm) to about
1.5 ft. (50 cm)
2About 0.8 ft. (25 cm) to about
1.1 ft. (37.5 cm)
3Less than about 0.8 ft. (25 cm)
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
(automatic transmissions), or the park-
ing brake is set (manual transmis-
sions). 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 parking as-
sist− sensor warns the driver by continu-
ous 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 parking
assist− sensor 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.
