⬛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.

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

WARNING
⦁Moving objects (those appearing sudd enly or traveling across the vehicle)
⦁ Sponge-like items or obstacles with soft surfaces such as snow, which are
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
causes

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.

WARNING
⬛The ABS does not operate effectively when
⚫Do not overly rely on the ABS.
The limits of tire gripping performance have been exceeded (such as exces-
sively worn tires on a snow covered road).
⚫The vehicle hydroplanes while driving at high speed on wet or slick roads.
⬛Stopping distance when the ABS is operating may exceed that of normal
conditions
The ABS is not designed to shorten th e vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations:
⚫When driving on dirt, grav el or snow-covered roads
⚫When driving with tire chains
⚫When driving over bumps in the road
⚫When driving over roads with potholes or roads with uneven surfaces
⬛TRC/VSC may not operate effectively when
⚫Do not overly rely on the TRC/VSC.
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/VSC system is operating.
Drive the vehicle carefully in condit ions where stability and power may be
lost.
⚫The VSC and TRC may not function proper ly when tire chains are installed.
⬛Hill-start assist control does not operate effectively when
⚫Do not overly rely on hill-start assist control. Hill-start assist control may not
operate effectively on steep inclines an d dirt, gravel or snow-covered roads.
⚫Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use hill-
start assist control to hold the vehicle on an incline, as doing so may lead to
an accident.
⚫The hill-start assist control may no t become activated depending on the
number of occupants or luggage weight in the vehicle, or if the driver did not
step on the brake pedal strong enough when stopping.
⬛When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
⬛When the ABS warning light or slip indicator is on
The emergency brake signal ( ➞P. 232) may not be activated.

⬛When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions.
As these are the systems to help ensure vehicle stability and driving force, do
not turn the TRC/VSC systems off unless necessary.
⬛Replacing tires
Make sure that all tires are of the spec ified size, brand, tread pattern and total
load capacity. In addition, make sure th at the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRC and VSC systems will not func tion correctly if different tires are
installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
⬛Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the
driving assist systems, and may cause a system to malfunction.
