WARNING
■When using the intuitive parking
assist
Observe the following precautions.
Failing to do so may result in the vehicle
being unable to be driven safely and pos-
sibly cause an accident.
●Do not use the sensor at speeds in
excess of 6 mph (10 km/h).
●The sensors’ detection areas and reac-
tion times are limited. When moving
forward or reversing, check the areas
surrounding the vehicle (especially the
sides of the vehicle) for safety, and
drive slowly, using the brake to control
the vehicle’s speed.
●Do not install accessories within the
sensors’ detection areas.
NOTICE
■When using intuitive parking assist
In the following situations, the system
may not function correctly due to a sen-
sor malfunction etc. Have the vehicle
checked by your Lexus dealer.
●The intuitive parking assist operation
display flashes or shows continuously,
and a beep sounds when no obstacles
are detected.
●If the area around a sensor collides
with something, or is subjected to
strong impact.
●If the bumper or grille collides with
something.

■Detection range of the sensorsApproximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 2.0 ft. (60 cm)
The diagram shows the detection range of
the sensors. Note that the sensors cannot
detect obstacles that are extremely close
to the vehicle.
The range of the sensors may change depending on the shape of the object etc.
■Multi-information display, head-up
display and Center Display
Sensors that detect an obstacle will illu-
minate continuously or blink.
NOTICE
●If the display flashes or shows continu-
ously without beeping, except when
the mute function has been turned on.
●If a display error occurs, first check the
sensor.
If the error occurs even when there is
no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or
steam to the sensor area.
Doing so may result in the sensor mal-
functioning.

■Buzzer operation and distance to
an obstacle
A buzzer sounds when the sensors are
operating.
 The buzzer beeps faster as the vehi-
cle approaches an obstacle. When
the vehicle comes within the follow-
ing distance of the obstacle, the
buzzer sounds continuously:
• Front center sensors: Approximately 1.0
ft. (30 cm)
• Corner sensors: Approximately 1.0 ft. (30 cm)
• Rear center sensors: Approximately 1.1 ft. (35 cm)
 When 2 or more obstacles are
detected simultaneously, the buzzer
system responds to the nearest
obstacle. If one or both come within
the above distances, the beep will
repeat a long tone, followed by fast
beeps.

WARNING
■Handling the radar sensor
Blind Spot Monitor se nsors are installed
behind the left and right sides of the rear
bumper respectively. Observe the fol-
lowing to ensure the Blind Spot Monitor
can function correctly.
●Keep the sensors and the surrounding
areas on the rear bumper clean at all
times.
If a sensor or its surrounding area on
the rear bumper is dirty or covered
with snow, the Blind Spot Monitor may
not operate and a warning message
(  P.221) will be displayed. In this situ-
ation, clear off the dirt or snow and
drive the vehicle with the operation
conditions of the BSM function
(  P.224) satisfied for approximately
10 minutes. If the warning message
does not disappear, have the vehicle
inspected by your Lexus dealer.

■Operation of the BSM function
The BSM function uses radar sensors to de tect the following vehicles traveling in
adjacent lanes and advises the driver of th e presence of such vehicles via the indi-
cators on the outside rear view mirrors.
Vehicles that are traveling in areas that are not visible using the outside rear
view mirrors (the blind spots)
WARNING
●Do not subject a sensor or its sur-
rounding area on the rear bumper to a
strong impact.
If a sensor is moved even slightly off
position, the system may malfunction
and vehicles may not be detected cor-
rectly.
In the following situations, have your
vehicle inspected by your Lexus
dealer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor is scratched or dented, or part of them
has become disconnected.
●Do not disassemb le the sensor.
●Do not attach stickers to the sensor or
surrounding area on the rear bumper.
