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 de-
pending on the shape of the object etc.
DCertain vehicle conditions and the sur-
rounding environment may affect the
ability of a sensor to correctly detect an
obstacle. Particular instances where
this may occur are listed below.
DThere is dirt, snow or ice on a sen-
sor.
DA sensor is frozen.
DA sensor is covered in any way.
DThe vehicle is leaning considerably
to one side.
DOn an extremely bumpy road, on an
incline, on gravel, or on grass
DThe vicinity of the vehicle is noisy
due to vehicle horns, motorcycle
engines, air brakes of large ve-
hicles, or other loud noises produc-
ing ultrasonic waves.
DThere is another vehicle equipped
with parking assist sensors in the vi-
cinity.
DA sensor is coated with a sheet of
spray or heavy rain.
DThe vehicle is equipped with a fend-
er pole or radio antenna.
DTowing eyelets are installed.
DA bumper or sensor receives a
strong impact.
DThe vehicle is approaching a tall or
right− angled curb.
DIn harsh sunlight or intense cold
weather.
DA non− genuine Lexus suspension
(lowered suspension, etc.) is
installed.
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.
