■Vehicles that can be detected
by the Blind Spot Monitor
The BSM function uses radar sen-
sors to detect the following vehicles
traveling in adjacent lanes and
advises the driver of the presence
of such vehicles via the indicators
WARNING
■Handling the radar sensor
Blind Spot Monitor sensors are
installed inside the left and right sides of the rear bumper respectively.
Observe the following to ensure the
Blind Spot Monitor can function cor - rectly.
●Keep the sensor s 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.394) will be displayed. In this s ituation, clear off
the dirt or snow a nd drive the vehi-
cle with the operation conditions of the BSM function ( →P.410) satis-
fied for approximately 10 minutes. If
the warning message does not dis - appear, have the v ehicle inspected
by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
●Do not subject a sensor or its sur - rounding area on the rear bumper
to a strong impact.
If a sensor is moved even slightly off position, the system may mal-
function and vehicles may not be
detected correctly. In the following situations, have
your vehicle inspected by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor
is scratched or dented, or part of them has become disconnected.
●Do not disassemble the sensor.
●Do not attach acce ssories, stickers
(including transparent stickers), alu - minum tape, etc. to a sensor or its
surrounding area on the rear
bumper.
●Do not modify the sensor or sur -
rounding area on the rear bumper.
●If a sensor or the rear bumper
needs to be removed/installed or replaced, contact any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
●Do not paint the rear bumper any
color other than an official Toyota color.

WARNING
■Toyota parking assist-sensor
precautions
Observe the following precautions. Failing to do so may result in the vehi -
cle being unable to be driven safely
and possibly cause an accident.
●Do not use the sensor at speeds in
excess of 10 km/h (6 mph).
●The sensors’ detection areas and
reaction times are limited. When moving forward or reversing, check
the areas surrounding 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 acce ssories near the
bumpers as those areas are within the sensors’ detection areas.

4165-5. Using the driving support systems
■The system can be operated when
●The power switch is in ON.
●Toyota parking assist-sensor function is on.
●The vehicle speed is less than about 10 km/h (6 mph).
●The shift lever is in other than P.
■If “Clean Parking Assist Sensor” is
displayed on the multi-information display
A sensor may be covered with ice,
snow, dirt, etc. Rem ove 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 system will return to normal.
If a warning message is displayed even
if the sensor is cle an, there may be a sensor malfunction. Have the vehicle
inspected by any a uthorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
●The area directly under the bum -
pers 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 colli -
sion.
●The vehicle is equipped with a com - mercial fender pole, wireless
antenna or fog lights.
●The front or rear bumper or a sen -
sor receives a strong impact.
●A non-genuine Toyota suspension
(lowered suspension, etc.) is
installed.
●Towing eyelets are installed.
●A backlit license plate is installed.
●When using an automatic car wash
■When using the Toyota parking
assist-sensor
In the following situations, the system
may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
●The Toyota parki ng assist-sensor
operation display flashes or shows continuously, a nd a beep sounds
when no objects are detected.
●If the area around a sensor collides
with something, or is subjected to
strong impact.
●If the bumper or grille collides with
something.
●If the display flashes or is displayed continuously and a buzzer does not
sound, except when the mute func -
tion has been turned on.
■Notes when washing the vehicle
Do not apply intensiv e 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 malfunc -
tion.
●When using steam to clean the
vehicle, do not direct steam too close to the sensors as doing so
may cause a sensor to malfunction.
