WARNING
■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-

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 your Toyota
dealer. If the fr ont or rear
bumper needs to be
emoved/installed or replaced,
contact your Toyota dealer.
●Do not modify, disassemble or
paint the sensors.

■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.

or lowered due to the carried load.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning.
●When a tire chains, compact
spare tire or an emergency tire
puncture repair kit is used.
■Situations in which the system
may operate even if there is no
possibility of a collision
In some situations, such as the fol-
lowing, the system may operate
even though there is no possibility of
a collision.
●When driving on a narrow road.
●When driving towa rd a banner,
flag, low-hanging branch or boom
barrier (such as those used at rail-

(grating), such as those used for
drainage ditches.
●When driving up or down a steep
slope.
●If a sensor is hit by a large amount
of water, such as when driving on
a flooded road.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
