The back sensor only operates when
the transmission is in “R” (automatic
transmission) or reverse (manual
transmission), it checks the approxi-
mate distance to obstacles close to the
rear of the vehicle, and sounds a warn-
ing depending on the distance. 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 than about 1.1 ft. (35
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 1.1 ft. (35 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 1.1 ft. (35 cm).
CAUTION
When reversing, be sure to visually
confirm a safe distance around your
vehicle to avoid an accident.

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.

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 Lexus parking assist
−sensor may
not work properly in the following
cases:
DWhen the bumper is damaged.
DWhen the part near the sensors is sub-
jected to a strong impact.
DWhen an accessory is installed within
the sensor detection range.
DWhen snowflakes or mud gets on the
sensors.
(If removed, the parking assist− sensor
will work properly.)
DWhen water is splashed from a high
pressure car wash or steam on the
sensors.
DWhen a sensor is covered with your
hand.
DWhen the vehicle is tilted.
DIn extreme hot or cold weather
(In extreme cold weather, the error dis-
play appears and the parking assist −
sensor becomes inoperative.)
DWhen driving on bumpy roads, slopes,
gravelled roads or grass.
DDevices 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.

hicle.
DWhen you are driving towards a tall
curb stone or curb stone having right
angle.
DThe detection range for an object such
as a traffic sign may be shortened.
DAn 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.
DWhen an obstacle is very close to the
sensors.
The Lexus parking assist −sensor may
not detect the following:
DThin objects such as wire or rope
DSound wave absorbing objects such as
cotton or snow
DObjects with a sharp edge
DTall objects with the upper part project-
