: If equipped
Vehicles without a navigation/multimedia system:
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 multi-information display
and a buzzer. Always check the surrounding area when using
this system.
Vehicles with a navigation/multimedia system:
Refer to the “Navigation and multimedia system Owner’s man-
ual”.

■The Toyota parking assist-sensor can be operated when
The power switch is in ON mode.
● Front sensors:
• The shift position is shifted to a position other than P.
• The vehicle speed is less than about 10 km/h (6 mph).
(At any speed when the shift position is in R)
● Rear sensors:
The shift position is in R.
■ Sensor detection information
● 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.
• A sensor is frozen.
• A 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, motorcycle
engines, air brakes of large vehicles, or other loud noises producing ultra-
sonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelet is installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by the sensor to be
closer than they are.
● The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of
your vehicle

■ If “Clean sonar.” is displayed on the multi-information display
A sensor may be dirty or covered with snow or ice. In this case, clean the
sensor and the system should return to normal.
If a sensor is frozen due to low temperatures, a warning message may be dis-
played or an obstacle may not be detected. When the sensor thaws out, the
system should return to normal.
■ If “Check sonar system.” is displayed on the multi-information display
The system may not operate due to the malfunction of a sensor.
Have the vehicle inspected by any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
WARNING
■ Caution when using the Toyota parking assist-sensor
Observe the following precautions.
Failing 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 10 km/h (6 mph).
● Do not attach any accessories within the sensor range.
NOTICE
■Notes on the Toyota parking assist-sensor
● Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
● If your vehicle is involved in an accident, it will affect the sensors and may
result in a system failure.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional.

Simple-IPA (Simple- Intelligent Parking
Assist)
: If equipped
Simple-IPA is a system that ass ists parallel parking operations.
When parking between two parked vehicles or in the space
behind one parked vehicle, the sensors installed on the sides of
the front bumper are utilized a nd a space which the vehicle can
be parked in is detected. Park ing operations are then assisted
by automatic operation of the steering wheel.

While the steering wheel is turning, keep the vehicle at a complete stop.
When the steering wheel stops turning, move the vehicle forward slowly
while checking the safety of the area in front of the vehicle.
When the front Toyota parking
assist-sensor’s warning buzzer

■ Toyota parking assist-sensor operation during Simple-IPA operation
Even if the Toyota parking assist-sensor is turned off while Simple-IPA is acti-
vated, the Toyota parking assist-sensor will keep operating. In this case,
when Simple-IPA operation is complete or canceled, the Toyota parking
assist-sensor will be deactivated.
■ When the cabin temperature is high
The sensors may not work properly when the cabin temperature is high due
to parking the vehicle in the sun. Use Simple-IPA after the cabin cools down.
■ Sensors used by Simple-IPA
 P. 284
■ Initializing Simple-IPA
Within 15 seconds of turning the Simple-IPA switch on, turn the steering
wheel all the way to the left or right and then to the opposite side.
When the parking space detection screen is displayed, the initialization is
complete.
If pressing the Simple-IPA switch again still shows “IPA not available, stop the
vehicle, turn wheel from left end to ri ght end.” on the multi-information display,
the initialization has failed. Have the vehicle inspected at any authorized
Toyota dealer or repairer, or another duly qualified and equipped professional.
WARNING
■ Cautions regarding the use of Simple-IPA
● Never depend on the Simple-IPA entirely when parking. The driver is
responsible for safety. Use caution, just as you would when parking any
vehicle.
● Back up slowly, using the brake pedal to control the vehicle's speed.
● If it seems likely to hit nearby vehicles, obstacles, or people, depress the
brake pedal to stop the vehicle, and the disable the system.
