Front corner sensors✽/Reverse sensors✽
The front corner sensors and reverse sensors are the system that
uses the sonar to recognize the approximate distance between the
vehicle and the obstacle, and that notifies the driver of its presence
by the buzzer and display indica tors when the vehicle speed is
approx. 10 km/h (6 mph) or less.
Sonar positions and types
a Front sonar
The front corner sensors are used to
recognize necessary information.
bRear sonar
The reverse sensors are used to recog-
nize necessary information.
Switching front corner sensors and reverse sensors
(For vehicles with front corner sensors)
Press the switch
Pressing the switch turns on the front
corner sensors or reverse sensors and
lights up the switch-on indicator.
To turn it off, press the switch again.
How to display the front corner sensors or reverse sensors
Once an obstacle is recognized, they
are displayed automatically.

How to read the distance display
When an obstacle is recognized while all the activation conditions are sat-
isfied, the driver is notified of its presence by the buzzer and display indi-
cators.
⚫The buzzer will sound when the parking brake is not applied.
⚫When the distance to the obstacle becomes shorter, the buzzer and dis-
play indicators will change, as shown in the figure below.
▶Vehicles with multi-information display
▶Vehicles with TFT color multi-information display
⚫When sonar has recognized more than one obstacle simultaneously, the
buzzer for the closest obstacle will sound.

Sonar’s obstacle recognition range
The recognition areas are shown in
the right figure.
However, if the obstacle is too close
to the sonar, the recognition fails.
Depending on the obstacles’ shape
and conditions, the recognition
range may become shorter, or the
recognition may fail.
⬛Operating conditions
⚫Front corner sensors:
⦁When the engine switch is “ON”
⦁ When the front corner sensors/reverse sensors switch is ON
⦁ When the shift lever is set in other than P, and the vehicle speed is approx.
10 km/h or less
⚫Reverse sensors:
⦁When the engine switch is “ON”
⦁ Vehicles with front corner sensors:
When the front corner sensors/reverse sensors switch is ON
⦁ When the shift lever is set in R, and the vehicle speed is approx. 10 km/h or
less
⚫When an obstacle is recognized with all the activation conditions satisfied
and the parking brake not being applied, the buzzer will sound.
⬛Sonar recognition capabilities
⚫The sonar recognition range is limited to the area around the sonar on the
front side of the vehicle and th e rear bumper of the vehicle.
⚫It takes some time from when the sonar recognizes an obstacle until the
front corner sensors or reverse sensors become activated. If the vehicle gets
too close to the obstacle before the buzzers sounds, the buzzer may not
sound even when the vehicle is traveling at a slow speed.
⚫While the audio or air conditioning system is turned on, the music or fan
noise makes the buzzer sound difficult to hear.

WARNING
⬛Before using the front corner sensors or reverse sensors
Make sure to observe the following precautions.
Failure to do so is dangerous, as it may lead to an unforeseen accident.
⚫Do not let the vehicle speed exceed approx. 10 km/h (6 mph).
⚫There is a limit to the sonar’s recognition range and activation speed. When
you move your vehicle forward or backward, make sure to check the safety
around the vehicle, which is outside the sonar’s recognition range (especially
the sides of the vehicle), use the brak e pedal to control the speed adequately
and drive slowly.
⚫Do not paste stickers or install accesso ries on the sonar sensors or their sur-
rounding areas.
⚫Vehicles with TFT color multi-informa tion display: If the warning message
“Sonar Sensor Function Stop” appears, check the sonar conditions. If the
warning message appears even when the sonar is not covered with rain,
snow, ice, or dirt, it could be due to a malfunction of the front corner sensors
or reverse sensors. Have the vehicl e inspected at your Toyota dealer.
⬛Front corner sensors and reverse sensors
In the following situations, the front corner sensors or reverse sensors may
not work normally and could lead to an unforeseen accident. Make sure to
drive carefully.
⚫Road conditions (slopes, unevenness, etc.)
⚫Vehicle’s maintenance conditions (brake-r elated issues, worn out tires, infla-
tion pressure, driving on a spare tire, etc.)
⚫Bad weather (heavy rain, snowstorm, fog, etc.)
⚫When the vehicle is signif icantly tilted by carrying a heavy load or being on
the surface with different height, or when the vehicle height has significantly
changed
⚫Distance from the obstacle, orientatio n or position (the obstacle is located
near the center of the vehicle)
⚫When driving on a steep slope
⚫When the sonar system cannot recognize the obstacle correctly (the follow-
ing cases in particular)
⦁ When an obstacle is extremely clos e to the sonar (when approaching too
close to the obstacle, the buzzer may change from continuous sound to
intermittent sound)
⦁ When an obstacle is located at a high position from the ground
⦁ Short obstacles
⦁ Small obstacles (such as small animals and infants), narrow obstacles
