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.

⬛When the high-pitch short beeps sound 3 times repeatedly and the front
corner sensor or reverse sensor ON indicator appears at 2 front locations
or 2 rear locations (or all 4 locations) simultaneously
⚫The front corner sensor or reverse se nsor functionality has been degraded.
When the front corner sensor or re verse sensor functionality temporarily
turns off, check if the sonar is not cove red with rain, snow, ice, or dirt. Remove
those attached to it, then wait for the f unctionality to be restored to normal.
⚫If the master warning light turns on at this time, it may indicate a malfunc-
tion of the system. Have the vehicle inspected at your Toyota dealer.
⚫Vehicles with TFT color multi-informati on display: Depending on the condi-
tions, the warning messages as “Son ar Sensor Function Stop” and “Sonar
Sensor Malfunction Visit Your Dealer” will be displayed.
⬛Front corner sensors and reverse sensors
In the following cases, the system ma y become activated even when there is
no obstacle within the operating range.
⚫When driving an area where the road slopes suddenly change
⚫When passing through plastic curtains or driving under flags
⚫When water splashes or drifting snow whirls up
⚫When passing an obstacle at close range
⚫When using an elevator for automobiles or using a mechanical parking lot
⚫When driving over a bump with an obstacle near the vehicle
⚫When there is an obstacle near the side of the vehicle
⚫When the road surface has large bumps, curbstones or protrusions, or when
the ground surface has tire tracks and holes
⚫When entering into a tight space
⚫During pouring rain or when water splashes over the vehicle
⚫Bad weather (heavy rain, snowstorm, fog, etc.)
⚫When the following is present near the vehicle: the sound of other vehicles’
horns, motorcycle engines, and air brakes of large vehicles, the devices emitting
ultrasonic waves, such as vehicle detect ors, or sonar systems of other vehicles
⚫When commercially available electrical components (such as an internally illu-
minated number plate, radio antenna) are installed near the sonar sensors
⚫When the vehicle body has been considerably tilted
⚫When the vehicle height has significantly changed by the load conditions, etc.
⚫When the direction of the sonar sensors is deviated by a collision or other
causes
⚫When the sonar sensors are covere d with rain, snow, ice or dirt

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

likely to absorb sound waves
⦁ When the obstacle’s surface is diagonal to the vehicle
⦁ A wall that is not perpendicular to the ground
⦁ Non-planar walls, such as those with uneven or wavy surface
⦁ Thin obstacles such as wires, wire mesh , ropes, road signs, utility poles and
other poles
⦁ When pillars or pipes are sticking out from the wall
⦁ When an unrecognizable obstacle is located between a recognizable
obstacle and the vehicle
⦁ Obstacles located outside of the sonar’s recognition range
⦁ When the sonar sensor areas are extremely hot under the blazing sun or
extremely cold during winter
⦁ When the sonar sensors are covere d with rain, snow, ice or dirt
⦁ During pouring rain or when water splashes over the vehicle, or strong
wind blowing
⦁ When there is a loud noise around, or there are devices emitting ultra-
sonic waves (the sound of other vehicles’ horns, motorcycle engines, and
air brakes of large vehicles, vehicle detectors, or sonar systems of other
vehicles)
⦁ When commercially availa ble electrical components (such as an internally
illuminated number plate, radio anten na) are installed near the sonar sen-
sors
⦁ When the direction of the sonar sensors is deviated by a collision or other

: If equipped
Rear-view camera✽
The rear-view camera is a device designed to assist driving when the
vehicle backs up, such as during pa rking, by displaying the vehicle’s
rear-view image on the display audio screen.
The operation may differ depending on the display audio your vehi-
cle has. For details, refer to the included instruction manual.
The screen illustration used in this document is an example. The actual
image displayed will be different from this illustration in terms of how the
vehicle appears. Rear-view camera screen display
When the shift lever is set to R with the engine switch turned “ON”, the dis-
play audio screen shows the vehicle’s rear-view image.
Setting the shift lever to other than R will restore the previous screen.
The rear-view camera image takes prec edence over any other screen dis-
play.

⚫The projection range may be different depending on the vehicle and
road conditions.
⚫The projection range of the rear-view camera is limited. The camera
does not capture items located near both edges of the bumper or those
located under the bumper.
⚫Since the rear-view camera uses a special lens, the distance in the cam-
era view is different from the actual distance.
⚫The colors of the rear-view camera image may appear different from the
actual colors.
⚫Anything placed above the rear-view camera may not appear on the
monitor.
⬛Camera
The rear-view camera is installed at
the following location.
⚫Camera maintenance and care
If foreign objects, such as water dr oplets, snow, or dirt, are attached to
the camera, you cannot see a clear image. In this case, wash out dirt
from the camera with water, and wipe it off with a soft cloth dampened
with water. For persistent stains, wash it off with neutral detergent.
⚫The following situations may make it diff icult to view the screen, but they are
not the sign of malfunction.
⦁ Dark places (such as at night)
⦁ When the temperature near the lens is high or low
⦁ When water droplets are attached to th e rear-view camera or the humidity is
high (such as during rain)
⦁ When foreign objects (including dirt) are attached near the rear-view camera
⦁ When the sunlight or the headlight be am has directly shined on the lens of
the rear-view camera

WARNING
⬛Rear-view camera
Failure to observe the following may cause death or serious injury.
⚫Do not overly rely on the rear-view camera. Just as when you drive a vehicle
without the rear-view camera, make su re to check the safety around and
behind your vehicle and drive carefully. Be particularly careful not to collide
with the parked vehicles nearby, obstacles, or people.
⚫When you back up, make sure to check the safety around and behind your
vehicle and drive carefully.
⚫Never drive the vehicle while looking at the screen only.
The image displayed on the screen ma y be different from the actual situa-
tion. Note that the projection range of the camera is limited. Never back up
while looking at the screen only. Doing so could get your vehicle hit or lead
to an unforeseen accident. Be sure to confirm the safety around by visually
checking the surroundings with your ey es or using the inside rear view mir-
ror and the outside rear view mirrors before driving.
⚫Never use it in the situations listed below.
⦁ Frozen, slippery or snowy roads
⦁ When tire chains or spare tires are used
⦁ When the back door is not closed fully
⦁ On a non-flat road surface such as slopes
⚫If the outside temperature is low, the screen may be come dark and the
image may become blurry. Especially since the moving objects may appear
blurred or disappear from the screen, always check the safety around you
directly with your eyes while driving.
