■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 does not indicate a
malfunction.
● The front sensor is misaligned due to a strong impact being applied to the
sensor, etc.
● Dirt, snow, stickers, etc., are on the windshield near the front sensor.
● In inclement weather such as heavy rain, fog, snow or sand storms
● Light from an oncoming vehicle, the sun, etc., enters the front sensor.
● The sign is small, dirty, faded, tilted or bent, and if an electronic sign, the
contrast is poor.
● All or part of the sign is hidden by the leaves of a tree, a pole, etc.
● The sign is only visible to the front sensor for a short amount of time.
● The driving scene (turning, lane change, etc.) is judged incorrectly.
● Even if it is a sign not appropriate for the currently traveled lane, such a sign
exists directly after a freeway branches, or in an adjacent lane just before
merging.
● Stickers are attached to the rear of the preceding vehicle.
● A sign resembling a system compatible sign is recognized.
● The vehicle is driven in a country with a different direction of traffic.
● Side road speed signs may be detected and displayed (if positioned in sight
of the front sensor) while the vehicle is traveling on the main road.
● Roundabout exit road speed signs may be detected and displayed (if posi-
tioned in sight of the front sensor) while traveling on a roundabout.
● The speed information displayed on the meter and that displayed on the
Navigation system (if equipped) may be different due to the Navigation sys-
tem using map data.

Types of sensors
Toyota parking assist-sensor∗
∗: 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”.

■Enabling/disabling the Toyota parking assist-sensor system
This system can be enabled/disabled on the multi-information dis-
play.Display the settings display ( →P. 106), and then press /
on the meter control switches to select .
Press on the meter con-
trol switches to enable/dis-
able the system.
When enabled, the Toyota
parking assist-sensor indica-
tor will illuminate.
When the sensors detect an obstacle, a graphic is shown on the multi
information display depending on the position and distance to the
obstacle. Front center sensor operation

sensors cannot detect obstacles
that are extremely close to the
vehicle.

■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 su rrounding 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.
