WARNING
■Handling the rear side radar
sensor
Blind Spot Monitor sensors are
installed behind the left and right
sides of the rear bumper respec-
tively. Observe the following to
ensure the Blind Spot Monitor can
operate correctly.
●Keep the sensors and the sur-
rounding areas on the rear
bumper clean at all times.
If a sensor or its surrounding area
on the rear bumper is dirty or cov-
ered with snow, the Blind Spot
Monitor may not operate and a
warning message (
P.286) will
be displayed. In this situation,
clear off the dirt or snow and drive
the vehicle with the operation con-
ditions of the BSM function
(
P.290) satisfied for approxi-
mately 10 minutes. If the warning
message does not disappear,
have the vehicle inspected by
your Toyota dealer.
●Do not attach stickers to the
sensor or surrounding area on
the rear bumper.

■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 driver of
the presence of such vehicles via the indicators on the outside rear
view mirrors.
WARNING
●Do not subject a sensor or its
surrounding area on the rear
bumper to a strong impact.
If a sensor is moved even
slightly off position, the system
may malfunction and vehicles
may not be detected correctly.
In the following si tuations, have
your vehicle inspected by your
Toyota dealer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sen- sor is scratched or dented, or
part of them has become dis-
connected.
●Do not disassemble the sensor.
●Do not modify the sensor or sur-
rounding area on the rear
bumper.
●If a sensor or th e rear bumper
needs to be removed/installed
or replaced, contact your Toyota
dealer.
●Do not paint the rear bumper
any color other than an official
Toyota color.

takes your vehicle.
●You overtake a vehicle in an adja-
cent lane slowly.

WARNING
■When using the intuitive park-
ing assist
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 use the sensor at
speeds in excess of 6 mph (10
km/h).
●The sensors’ detection areas
and reaction times are limited.
When moving forward or revers-
ing, check the areas surround-
ing the vehicle (especially the
sides of the vehicle) for safety,
and drive slowly, using the
brake to control the vehicle’s
speed.
●Do not install accessories within
the sensors’ d etection areas.
●The area directly under the
bumpers is not detected.
Thin posts or objects lower than
the sensor may not be detected
when approached, even if they
have been detected once.
■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.
●The vehicle is equipped with a
fender pole, wireless antenna or
fog lights.
●The front or rear bumper or a
sensor receives a strong
impact.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)
is installed.
●Towing eyelets are installed.
●A backlit licence plate is
installed.
■When using intuitive parking
assist
In the following situations, the
system may not function correctly
due to a sensor malfunction, etc.
Have the vehicle checked by your
Toyota dealer.
●The intuitive parking assist
operation display flashes or
shows continuously, and a
buzzer sounds when no objects
are detected.
●If the area around a sensor col-
lides with something, or is sub-
jected to strong impact.
●If the bumper or grille collides
with something.
●If the display flashes or is dis-
played continuously and a
buzzer does not sound, except
when the mute function has
been turned on.
●If a display error occurs, first
check the sensor.
If the error occurs even when
there is no ice, snow or mud on
the sensor, it is likely that the
sensor is malfunctioning.
■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.

■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 lever other than P.
■If “Parking Assist Unavailable”
is displayed on the multi-infor-
mation display
●Water may be continuously flow-
ing over the sensor surface, such
as in a heavy rain. When the sys-
tem determines that it is normal,
the system will return to normal.
●Initialization may not have been
performed after a battery terminal
was disconnected and recon-
nected. Initialize the system.
(  P.295) If this message contin-
ues to be displayed even after ini-
tialization, have the vehicle
inspected by you r Toyota dealer.
■If “Parking Assist Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion display
A sensor may be covered with ice,
snow, dirt, etc. Remove the 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 12-volt battery 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.
■Sensor detection information
●The following situations may occur
during use.
• The sensor's detec tion areas are
limited to the areas around the
vehicle front and rear bumpers.
• Depending on the shape of the object and other factors, the
detection distance may shorten, or
detection may be impossible.
• If an object is extremely close to a sensor, it may not be detected.
• There will be a short delay between object detection and dis-
play. Even at low speeds, there is
a possibility that the object will
come within the sensor’s detec-
tion areas before the display is
shown and the warning beep
sounds.
• It might be diffic ult to hear the
buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
• It may be diffi cult to hear the
buzzer if buzzers for other sys-
tems are sounding.
■Conditions under which the
function may not function cor-
rectly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly
detect objects. Part icular instances
where this may occur are listed
below.
●There is dirt, snow or ice on a sen-
sor. (Cleaning the sensors will
resolve this problem.)
●A sensor is froz en. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
WARNING
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sens or to malfunc-
tion.

2964-5. Using the driving support systems
HIGHLANDER HV_Uplay may be displayed abnormally,
or objects, such as a wall, may not
be detected.
●A sensor is covered in any way.
●When a sensor or the area around
a sensor is extremely hot or cold.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●The vicinity of the vehicle is noisy
due to vehicle horns, motorcycle
engines, air brakes of large vehi-
cles, or other l
oud noises produc-
ing ultrasonic waves.
●There is another vehicle equipped
with parking assist sensors in the
vicinity.
●A sensor is coated with a sheet of
spray or heavy rain.
●If a sensor is hit by a large amount
of water, such as when driving on
a flooded road.
●If the vehicle is sig nificantly tilted.
●The vehicle is approaching a tall
or curved curb.
●If objects draw too close to the
sensor.
■Objects which may not be prop-
erly detected
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the follow-
ing objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
People may not be detected if they
are wearing certain types of cloth-
ing.
■Adjusting the buzzer vol-
ume
The buzzer volume can be
adjusted on the multi-informa-
tion display.

■Muting a buzzer temporarily
A mute button will be displayed
on the multi-information display
when an object is detected. To
mute the buzzer, press .
Mute will be canceled automati-
cally in the following situations:
 When the shift lever is
changed.
 When the vehicle speed
exceeds a certain speed.
