WARNING
■When using the intuitive parking assist
Observe the following precautions.
Failure to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
● Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● The sensors’ detection areas and reaction times are limited. Wh en revers-
ing, check the areas surrounding the vehicle (especially the sides of the
vehicle) for safety, and drive sl owly, using the brake to control the vehicle’s
speed.
● Do not install accessories within the sensors’ detection areas.

WARNING
■Sensor detection information
Pay particular attention to the following instances in where th is may occur.
Failing to do so way result in the vehicle being unable to be d riven or parked
safety and possibly cause an accident.
● The sensor’s detection areas are limited to the areas around the vehicle’s
rear bumper.
● Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)
• The sensor is frozen. (Thawing the area will resolve this prob lem.)
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, mot orcycle
engines, air brakes of large vehicles, or other loud noises pro ducing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
• A backlit license plate, license plate holder, etc., are insta lled.
• People may not be detected if they are wearing certain types a nd color-
ing of clothing.
• People, animals, and moving objects may not be able to be detected.
In addition to the examples above, there are instances in which , because of
their shape, signs and other objects may be judged by the senso r to be
closer than they are.

When trouble arises
*3: Driver’s seat belt buzzer:The driver’s seat belt warning buzzer sounds to alert the drive r that his or
her seat belt is not fastened. Once the engine switch is turned to the “ON”
position (vehicles without smart entry & start system) or IGNIT ION ON
mode (vehicles with smart entry & start system), the buzzer sou nds. If the
seat belt is still unfastened, the buzzer sounds intermittently for a certain
period of time after the vehicle reaches a certain speed.
Front passenger’s seat belt buzzer:
The front passenger's seat belt warning buzzer sounds to alert the front
passenger that his or her seat belt is not fastened. If the sea t belt is unfas-
tened, the buzzer sounds intermittently for a certain period of time after the
vehicle reaches a certain speed.
*4: Parking brake engaged warning buzzer:
A buzzer will sound if the vehicle is driven at a speed of approximately
3 mph (5 km/h) or more.
*5: If equipped
■ SRS warning light
This warning light system monitors the airbag sensor assembly, front impact
sensors, side impact sensors (front), side impact sensors (rear ), driver’s seat
position sensor, driver’s seat belt buckle switch, front passen ger occupant
classification system (ECU and sensors), “AIR BAG ON” indicator light, “AIR
BAG OFF” indicator light, front passenger’s seat belt buckle switch, seat belt
pretensioners assemblies, airbags, interconnecting wiring and power
sources. ( P. 38)
■ Front passenger detection sensor, seat belt reminder and warnin g
buzzer
● If luggage is placed on the front passenger seat, the front pas senger detec-
tion sensor may cause the warning light to flash and the warnin g buzzer to
sound even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passenger,
and the warning light may not operate properly.
