When driving
L/C200_EE (OM60G38E)Buzzer operation and distance to an obstacle
A beep sounds when the corner sensors and rear center sensors
are operating.
The buzzer beeps faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the obsta-
cle, the buzzer sounds continuously:
• Front corner sensors: Approximately 25 cm (0.8 ft.)
• Rear corner sensors: Approximately 30 cm (1.0 ft.)
• Rear center sensors: Approximately 50 cm (1.6 ft.)
When 2 or more obstacles are detected simultaneously, the beep
system responds to the nearest obstacle. If one or both come
within the above distances, the beep will repeat a long tone, fol-
lowed by fast beeps.
You can change the volume of the warning beeps. (P. 243)

Detection range of the sensors
Approximately 60 cm (2.0 ft.)
Approximately 150 cm (4.9 ft.)
Approximately 50 cm (1.6 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.

Sensor detection information
The sensor’s detection areas are limited to the areas around the vehi-
cle’s front corner and rear bumpers.
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 problem.)
In especially cold weather, if a sensor is frozen the screen may show
an abnormal display, or obstacles may not be detected.
• 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, motorcycle
engines, air brakes of large vehicles, or other loud noises producing
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 wireless antenna.
• Towing eyelets are installed.
• 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.
• People may not be detected if they are wearing certain types of cloth-
ing.
In addition to the examples above, there are instances in which, because
of their shape, signs and other objects may be judged by the sensor to be
closer than they are.

L/C200_EE (OM60G38E)
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
The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detec-
tion distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor
• There will be a short delay between obstacle detection and display.
Even at slow speeds, there is a possibility that the obstacle will come
within the sensor’s detection areas before the display is shown and the
warning beep sounds.
• Thin posts or objects lower than the sensor may not be detected for
collision when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or
air flow noise of air conditioning system.

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).
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.
NOTICE
When using Toyota parking assist-sensor
In the following situations, the system may not function correctly due to a
sensor malfunction etc. Have the vehicle checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional,
immediately.
A beep does not sound when you turn the main switch on.
The Toyota parking assist-sensor operation display flashes, and a beep
sounds when no obstacles are detected.
If the area around a sensor collides with something, or is subjected to
strong impact.
If the bumper collides with something.
If the display shows continuously without a beep.
If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
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.

Vehicle height modes
Press “ ” to step up one height mode, and “ ” to step down one
height mode. (Ex. When in the low height mode, press “ ” once to
switch to the normal height mode, and twice to switch to the high
height mode.)
“HI” (high) height mode
Vehicle height is about 50 mm (2.0 in.) higher at the front, and
about 60 mm (2.4 in.) higher at the rear than the normal mode
height.
This mode is suitable when driving on bumpy roads or through
water.
High height mode is only available when the vehicle speed is under
30 km/h (18 mph).
“N” (normal) height mode
The standard vehicle height. This mode is suitable for ordinary
driving.
When driving at high speeds, the vehicle height is automatically
lowered by 20 mm (0.8 in.) in the front and 15 mm (0.6 in.) in the
rear, to ensure excellent aerodynamic characteristics and stability.
If the vehicle speed drops, normal height mode is automatically
resumed.
“LO” (low) height mode
Vehicle height is about 60 mm (2.4 in.) lower at the front, and about
40 mm (1.6 in.) lower at the rear than the normal mode height.
This mode allows easy access to the vehicle.
Low height mode is only available when the vehicle is travelling at
12 km/h or less. When the vehicle speed exceeds 12 km/h (7
mph), normal height mode is automatically selected.
