extremely close to the vehicle.
The range of the sensors may change
depending on the shape of the object
etc.There is dirt, snow or ice on a sensor.
A sensor is frozen.
A sensor is covered in any way.
The vehicle is leaning considerably to
one side.
On an extremely bumpy road, on an

DETECTION RANGE OF THE
SENSORSSENSOR DETECTION
INFORMATION
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly de-
tect an obstacle. Particular instances
where this may occur are listed be-
low.
In addition to the examples above,
there are instances in which, because
of their shapes, signs and other
objects may be judged by a sensor to
be closer than they are.

The shape of the obstacle may prevent
a sensor from detecting it. Pay particu-
lar attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that
absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections pro-
jecting outwards in the direction of
your vehicle
CAUTION
Caution when using the Lexus park-
ing assist-sensor
Observe the following precautions.
Failing to do so may result in the
vehicle being unable to be driven
safely and possibly cause an accident.
• Do not use the sensor at speeds in
excess of 6 mph (10 km/h).
• Do not attach any accessories within
the sensor range.
Even though sensors which are func-
tioning properly continue to detect
obstacles, never use the Lexus park-
ing assist if one more sensor(s) may
be malfunctioning.
NOTICE
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
malfunctioning.
As the parking assist-sensor might be
malfunctioning in the following
cases, have it checked by any autho-
rized Lexus dealer or repairer, or
another duly qualified and equipped
professional.
• The graphic which indicates that an
obstacle has been detected does not
come on and a beep does not sound
even when the Lexus parking assist-
sensor mode is turned on.
• The graphic which indicates that an
obstacle has been detected comes on
despite no obstacle around the vehi-
cle.
• If your vehicle has been involved in
an accident.
• If the graphic which indicates that
an obstacles has been detected
remains on without a beeping sound.
