with trees (camping ground) or in

immediate environment that pre-
vent sensors from sufficiently 
detecting the trailer.
■Trailer Length Detection (TLD)
●Once a trailer is detected and if 
the trailer length in the meter is 
selected as “Auto”, the TLD func-
tion will estimate the
 trailer length 
using the Blind Spot Monitor sen-
sors. In order to estimate
 the trailer length 
with TLD function and detection 
area, make at least two 90 degree 
turns.
If the trailer length is entered manu-
ally via multi-information display 
input, the detection area is also 
adjusted to exceed the length of the 
trailer.
●Depending on some trailer types 
and the dimensions of the trailer 
TMW performance may be 
degraded.
■Vehicles that can be detected by the Blind Spot Monitor
The Blind Spot Monitor uses rear side radar sensors to detect the fol-
lowing vehicles traveling in adjacent lanes and advises the dri ver of 
the presence of such vehicles v ia the indicators on the outside rear 
view mirrors.
 When not towing a trailer
Vehicles approaching in adjacen t lanes that may not be visible

The distance from your 
vehicle to objects, such as a 
wall, when parallel parking 
or maneuvering into a 
garage is measured by the 
sensors and communi-
cated via the multi-informa-

WARNING
■Cautions regarding the use of 
the system
There is a limit t o the degree of 
recognition accuracy and control 
performance that this system can 
provide, do not overly 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. 

2764-5. Using the driving support systems
Owners Manual_USA_M0C031_en
■The system can be operated 
when
●The power switch is in ON.
●Intuitive parking assist function is 
on.
●The vehicle speed is less than 
about 6 mph (10 km/h).
●A shift position other than P is 
selected.
■If “Parking Assist Unavailable 
Clean Parking Assist Sensor” is 
displayed on the multi-informa-
tion display
A sensor may be covered with water 
drops, ice, snow, dirt, etc. Remove 
the water drops, ice, snow, dirt, etc., 
from the sensor to return the system 
to normal.
Also, due to ice forming on a sensor 
at low temperatures, a warning 
message may be displayed or the 
sensor may not be able to detect an 
object. Once the ice melts, the sys-
tem will return to normal.
If a warning message is displayed 
even if the sensor i s clean, there 
may be a sensor malfunction. Have 
the vehicle inspected by your Toyota 
dealer.
■If “Parking Assist Unavailable” 
is displayed on the multi-infor-
mation display
Water may be continuously flowing 
WARNING
●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 
removed/installed or replaced, 
contact your Toyota dealer.
●Do not modify, disassemble or 
paint the sensors.
●Do not attach a license plate 
cover.
●Keep your tires properly 
inflated.
■When to disable the function
In the following situations, disable 
the function as  it may operate 
even though there is no possibility 
of a collision.
●Failing to observe the warnings 
above.
●A non-genuine Toyota suspen-
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.

■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 toward a banner, 
flag, low-hanging branch or boom 
barrier (such as those used at rail-
road crossings, toll gates and 
parking lots)
●When there is a ru t or hole in the 
surface of the road
●When driving on a metal cover 
(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.)
●A sensor is coated with a sheet of 
spray or heavy rain
●When driving in inclement weather 
such as fog, snow or a sandstorm
●When strong winds are blowing
●When vehicle horns, vehicle 
detectors, motorcycle engines, air

●A sensor may be covered with 
water drops, ice, snow, dirt, etc. 
Remove the water drops, ice, 
snow, dirt, etc., from the sensor to 
return the system to normal.
Also, due to ice forming on a sen-
sor at low temperatures, a warn-
ing message may be displayed or 
the sensor may not be able to 
detect an object. Once the ice 
melts, the system will return to 
normal.
●If this message continues to be 
displayed even after cleaning the 
sensor, or is displayed even 
though the sensor is clean, have 
the vehicle inspected by your Toy-
ota dealer.
■If a 12-volt batte ry terminal has 
been disconnected and recon-
nected
The system needs to  be initialized. 
To initialize the system, drive the 
vehicle straight ahead for 5 seconds 
or more at a speed of approximately 
22 mph (35 km/h) or more.
This function will operate in situ-
ations such as the following if an 
object is detected in the travel-
ing direction of the vehicle.
Parking Support Brake 
function (static 
objects)
If the sensors detect a static 
object, such as a wall, in the 
traveling direction of the 
vehicle and the system 
determines that a collision 
may occur due to the vehi-
cle suddenly moving for-
ward due to an accidental 
accelerator pedal operation, 
the vehicle moving the 
unintended direction due to 
the wrong shift position 
being selected, or while 
parking or traveling at low 
speeds, the system will 
operate to lessen the impact 
with the detected static 
object and reduce the 
resulting damage.
