For safety and security
●The vehicle is inside an automatic or high-pressure car wash.
● The vehicle experiences impacts, such as hail, lightning strikes, and other
kinds of repeated impacts or vibrations.
● The vehicle is parked in a place where
extreme vibrations or noises occur, such
as in a parking garage.
● Ice or snow is removed from the vehicle,
causing the vehicle to receive repeated
impacts or vibrations.
NOTICE
■ To ensure the intrusion sensor functions correctly
● Installing accessories other than genuine Toyota parts or leaving objects
between the driver’s seat and front passenger’s seat may reduce the
detection performance.

● To ensure that the sensors operate
properly, do not touch or cover them.
● Do not spray air fresheners or other
products directly into the sensor holes.

■ Conditions under which the Rear Crossing Traffic Alert function will not
detect a vehicle
The Rear Crossing Traffic Alert function is not designed to detect the follow-
ing types of vehicles and/or objects:
● Vehicles approaching from directly behind
● Vehicles backing up in a parking space next to your vehicle
● Guardrails, walls, signs, parked vehicles and similar stationary objects*
●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles moving away from your vehicle
● Vehicles approaching from the parking spaces next to your vehicle*
*: Depending on the conditions, detection of a vehicle and/or object may
occur.
● Vehicles that the sensors cannot detect
due to obstructions

● Instances of the Rear Crossing Traffic Alert function unnecessarily detecting
a vehicle and/or object may increase in the following situations:
• When a vehicle passes by the side of your vehicle
• When the distance between your vehicle and metal objects, such as a
guardrail, wall, sign, or parked vehicle, which may reflect electrical waves
toward the rear of the vehicle, is short
• When the sensors cannot detect a
vehicle due to obstructions
• When the parking space faces a
street and vehicles are being driven
on the street

The Toyota parking assist-sensor
can be enabled/disabled on the
screen ( P. 250) of the
multi-information display.
When on is selected, Toyota park-
ing assist-sensor indicator will
come on.
Once off is selected, the Toyota parking assist-sensor will not return to on
until it is turned to on by the screen of multi-information display again.
(The system does not automatically return to on even when the hybrid sys-
tem is restarted.)
: If equipped
The distance from your vehicle to nearby obstacles when paral-
lel parking or maneuvering into a garage is measured by the
sensors and communicated via the displays and a buzzer.
Always check the surrounding area when using this system.

• The detection range is shown in
the illustration to the right. How-
ever, the sensor will not detect
the obstacle if it is too close.
• For details regarding obstacle
detection in the side areas.
( P. 465)
• The distance at which an obsta-
cle can be detected and whether
it can be detected depends on
the shape and condition of the
obstacle.
The obstacle detection range can be changed. ( P. 738)

■ If “Clean Parking Assist Sensor” is displayed on the multi-information
display
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an obstacle may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction” is displayed on the multi-information dis-
play
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
■ Customization
Setting of buzzer volume can be changed.
(Customizable features: P. 738)
WARNING
■When using Toyota parking assist-sensor
Observe the following precautions to avoid an unexpected accident.
● Do not exceed the speed limit 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 accessories within the sensors’ detection areas.
