In the following situations, the RSA syst em will notify the driver.
● When the vehicle speed exceeds the speed notification threshold of
the speed limit sign displayed, the sign display will be emphas ized
and a buzzer will sound.
● When the RSA system recognizes a do not enter sign and deter-
mines that your vehicle has ent ered a no-entry area, the displayed
sign will flash and a buzzer will sound.
Depending on the situation, a not ification function may not operate
properly.
■ Setting procedure
P. 151
■ Automatic turn-off of RSA sign display
In the following situations, a displayed speed limit sign and/o r do not enter
sign will stop being displayed automatically:
● No sign has been recognized for a certain distance.
● The road changes due to a left or right turn, etc.
In the following situations, stop and yield signs will stop bei ng displayed auto-
matically:
● The system determines that your vehicle has passed the sign.
● The road changes due to a left or right turn, etc.
■ Conditions in which the function may not operate or detect correctly
In the following situations, RSA does not operate normally and may not rec-
ognize signs, display the incorrect sign, etc. However, this do es not indicate a
malfunction.
● The front camera is misaligned due to a strong impact being applied to the
sensor, etc.

Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate su ffi-
ciently to prevent your vehicle fr om closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pushing the
cruise control lever up or depressing the accelerator pedal (st art-off opera-
tion) will resume follow-up cruising. If the start-off operatio n is not per-
formed, system control continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may b e deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side fr om where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking l ane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane
is to the right but then drives to a region where the overtaking lane is to the
left, the vehicle may accelerate when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The syst em then
returns to constant speed cruising.

WARNING
■To ensure the system can operate properly
● Keep the sensor and its surrounding area on the bumper clean at all times.
● 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 situations, 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 sensor is scratched or dented, or part of them has become disconnected.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor or surrounding area on
the bumper.

WARNING
■Cautions regarding the use of the system
There is a limit to the degree of recognition accuracy and cont rol perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicl e’s surround-
ings and driving safely.
■ To ensure the system can operate properly
Observe the following precautions to avoid an unexpected accident.
● Do not damage the sensors, and always keep them clean.
● Do not attach a sticker or install an electronic component, such as a backlit
license plate (especially fluorescent type), fog lights, fender pole or wire-
less antenna near a radar sensor.
● Do not subject the surrounding area of the sensor to a strong impact. If
subjected to an impact, have the vehicle inspected by your Toyota dealer.
If the front or rear bumper needs to be removed/installed or replaced, con-
tact your Toyota dealer.
● Do not modify, disassemble or paint the sensors.
● Do not attach a license plate cover.
● Keep your tires properly inflated.
■ 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.
● Failing to observe the warnings above.
● A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
■ Side sensors
In the following situations, the intuitive parking assist may n ot operate nor-
mally and may result in an unexpected accident. Drive carefully.
● Obstacles may not be detected in the side areas until the vehicle is driven
for a short time and a scan of the side areas is completed. ( P. 364)
● Even after the scan of the side areas is completed, obstacles s uch as
other vehicles, people or animals that approach from the sides cannot be
detected.
● Even after the scan of the side areas is completed, obstacles may not be
detected depending on the surrounding situation of the vehicle.
At that time, the side sensor operation displays ( P. 359) temporary turn
off.
■ Notes when washing the vehicle
● Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
● When using steam to wash the vehicle, do not direct steam too c lose to
the sensors. The sensors may not function properly if subjected to steam.

Assume an ordinary posture for backing up, rest your hands
lightly on the steering wheel without applying any force, direc tly
confirm the safety of the area t o the rear and around the vehic le,
confirm that there are no obsta cles in the parking space, and
slowly back up while adjusting your speed by depressing the
brake pedal.
● When backing up too quickly, a sharp beeping sound is emit-
ted and assist cont rol is stopped. (P. 386)
● When the vehicle cannot be cleanly entered within the target
parking spot on the first try and multi-turn maneuvering is nec -
essary, proceed to step .
When multi-turn maneuvering is not necessary, proceed to
step .3
