■Cautions regarding the use of
the system
There is a limit to the degree of
recognition accuracy and control
performance that this system can
provide, do not ov erly rely on this
system. The driver is always
responsible for paying attention to
the vehicle’ surroundings and
driving safely.
■To ensure the system can
operate properly
Observe the following precau-
tions.
Failing to do so may result in the
vehicle being unable to be driven
safely and possibly cause an acci-
dent.
●Do not damage the sensors,
and always keep them clean.
●Do not attach a sticker or install
an electronic component, such
as a backlit license plate (espe-
cially fluorescent type), fog
lights, fender pole or wireless
antenna near a radar sensor.
●Do not subject the surrounding
area of the sensor to a strong
impact. If subjected to an
impact, have the vehicle
inspected by Toyota dealer. If
the front or rear bumper needs
to be removed/installed or
replaced, contact your Toyota
dealer.

sion (lowered suspension, etc.)
is installed.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area.
Doing so may result in the sensor
malfunctioning.
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sensor to malfunc-
tion.

the vehicle approaches an
object. When the vehicle
comes within approximately
1.0 ft. (30 cm) of the object,
the buzzer sounds continu-
ously.
 When 2 or more sensors
simultaneously detect a static
object, the buzzer sounds for
the nearest object.
 Even when the sensors are
operating, the buzzer will be
muted in some situations.
