Detection range of the sensors 
Approximately 100 cm (3.2 ft.) 
Approximately 150 cm (4.9 ft.)
Approximately 60 cm (2.0 ft.)
The diagram shows the detection 
range of the sensors. Note that
the sensors cannot detect obsta-
cles that are extremely close to
the vehicle. 
The range of the sensors may 
change depending on the shape
of the object etc.
■ The Toyota parking assist-sensor can be operated when 
The Toyota parking assist-sensor switch is on. 
Vehicles without smart entry & start system: 
The engine switch is in “ON” position. 
Vehicles with smart entry & start system: 
The “ENGINE START STOP” switch is in IGNITION ON mode. 
● Front center sensors: 
• The shift lever is in a position other than “P” (Multidrive) or “R”. 
• The vehicle speed is less than about 10 km/h (6 mph). 
● Front corner sensors: 
• The shift lever is in a position other than “P” (Multidrive). 
• The vehicle speed is less than about 10 km/h (6 mph). 
● Rear corner and rear center sensors: 
• The shift lever is in “R”.

■ Sensor detection information 
● Certain vehicle conditions and the surrounding environment may affect 
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below. 
• There is dirt, snow or ice on a 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 vehicl es, or other loud noises producing 
ultrasonic 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 radio antenna.
• Towing eyelet is installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled 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 shape, signs and other objects may be judged by a sensor to be closer
than they are. 
● The shape of the obstacle may prevent a 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-angles objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle

■ When the sensor acts abnormal or malfunctions 
■ Customization that can be configured at any authorized Toyota dealer 
or repairer, or another duly qualified and equipped professional 
Setting of buzzer volume can be changed. 
(Customizable features P. 640)
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.
●When any of the sensors become dirty 
or frozen, the abnormal sensor indica-
tor comes on and the buzzer sounds for
8 seconds. After sounding, all of the
sensor indicators will come on. 
Clean the sensors with soft cloth. 
● When any of the sensors malfunction, 
the malfunctioning sensor indicator
flashes and the buzzer will sound for 8
seconds. After sounding, all of the sen-
sor indicators will flash. 
Have the vehicle inspected by any 
authorized Toyota dealer or repairer,
or another duly qualified and
equipped professional.

NOTICE
■ 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.

Maintenance and care
VERSO_EE_OM64590E
■ Aluminum wheels (if equipped) 
● Remove any dirt immediately by using a neutral detergent. Do not use 
hard brushes or abrasive cleaners. Do  not use strong or harsh chemical 
cleaners. Use the same mild detergent and wax as used on the paint. 
● Do not use detergent on the wheels when they are hot, for example after 
driving for long distance in the hot weather. 
● Wash detergent from the wheels immediately after use. 
■ Bumpers 
Do not scrub with abrasive cleaners.
WARNING
■ When cleaning the windshield (vehicles with rain-sensing windshield 
wipers) 
● When the upper part of the windshield where the raindrop sensor is 
located is touched by hand 
● When a wet rag or similar is held close to the raindrop sensor 
● If something bumps against the windshield 
● If you directly touch the raindrop sensor body or if something bumps into 
the raindrop sensor 
■ Caution about the exhaust pipe 
Exhaust gasses cause the exhaust pipe to become quite hot. 
When washing the vehicle, be careful not to touch the pipe until it has cooled 
sufficiently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off. 
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in hands
being caught or other serious injuries and
cause damage to the wiper blades.

VERSO_EE_OM64590E
NOTICE
■ Cleaning detergents 
● Do not use organic substances such as benzene or gasoline, acidic or 
alkaline solutions, dye, bleach or other detergent. Doing so may discolor
the vehicle interior or cause streaks or damage to painted surfaces. 
● Do not use polish wax or polish cleaner. The instrument panel’s or other 
interior part’s painted surface may be damaged. 
■ Preventing damage to leather surfaces 
Observe the following precautions to avoid damage to and deterioration of 
leather surfaces. 
● Remove any dust or dirt on leather surfaces immediately. 
● Do not expose the vehicle to direct sunlight for extended periods of time. 
Park the vehicle in the shade, especially during summer. 
● Do not place items made of vinyl, plastic, or that contain wax on the uphol- 
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly. 
■ Water on the floor 
Do not wash the vehicle floor with water. 
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components under the floor of the vehicle, and
may also cause the body to rust. 
■ When cleaning the inside of the windshield (vehicles with front sensor) 
Be careful not to touch the front sensor ( P. 263, 266). If the camera is acci- 
dentally scratched or hit, PCS (Pre-Collision System), LDA (Lane Departure
Alert) and Automatic High Beam may  not operate properly or may cause a 
malfunction. 
■ Cleaning the inside of the rear window 
● Do not use glass cleaner to clean the rear window, as this may cause 
damage to the rear window defogger heater wires. Use a cloth dampened
with lukewarm water to gently wipe the window clean. Wipe the window in
strokes running parallel to the heater wires. 
● Be careful not to scratch or damage the heater wires.
