LEXUS PARKING ASSIST−SENSOR
278
The Lexus parking assist−sensor 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 distance to an obstacle by
displaying information on the multi −in-
formation display 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 280.)
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 281.)
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 282.)
To use the parking assist −sensor, with
the “ENGINE START STOP” switch in
IGNITION ON mode, push “
”or“”
of the satellite switch to select the park-
ing assist− sensor and then push the
ON/OFF button. Selecting the parking
assist− sensor and pushing the ON/OFF
button of the satellite switch again will
turn the parking assist −sensor off.
When you turn on the parking assist −sen-
sor, the indicator light in the instrument
cluster comes on and a beep sounds for
one second, indicating that the parking as-
sist− sensor is turned on.
The parking assist −sensor 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 Lexus parking
assist− sensor while self −checking, beeps
sound and a warning appears in the multi −
information display and on the screen. For
details, see “ — Lexus parking assist −sen-
sor failure warning” on page 285.

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.
"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.
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.

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−

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

As distance to the obstacle gets closer, the

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.
