The distance display and buzzer
When a sensor detects an obstacle, the direction of and the approx-
imate distance to the obstacle are displayed and the buzzer sounds.
Distance display
Corner sensors
The system operates when the vehicle approaches within
approximately 50 cm (1.6 ft.) of an obstacle.
Approximately 37.5 cm (1.2
ft.) to 50 cm (1.6 ft.) from the
obstacle
Approximately 25 cm (0.8
ft.) to 37.5 cm (1.2 ft.) from
the obstacle
Flashing: Within 25 cm (0.8
ft.) of the obstacle
Rear center sensors
The system operates when the vehicle approaches within
approximately 150 cm (4.9 ft.) of an obstacle.
Approximately 60 cm (2.0
ft.) to 150 cm (4.9 ft.) from
the obstacle
Approximately 45 cm (1.5
ft.) to 60 cm (2.0 ft.) from the
obstacle
Approximately 35 cm (1.1
ft.) to 45 cm (1.5 ft.) from the
obstacle

CT200h_EE (OM76041E)Buzzer operation and distance to an obstacle
A buzzer sounds when the corner sensors and rear center sensor
are operating.
The buzzer beeps faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the
obstacle, the buzzer sounds continuously:
• Corner sensors:Approximately 25 cm (0.8 ft.)
•
Rear sensors: Approximately 35 cm (1.1 ft.)
When 2 or more obstacles are detected simultaneously, the
buzzer system responds to the nearest obstacle.
Detection range of the sensors
Approximately 50 cm (1.6
ft.)
Approximately 150 cm (4.9
ft.)
Approximately 50 cm (1.6
ft.)
The diagram shows the detec-
tion range of the sensors. Note
that the sensors cannot detect
obstacles 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
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 vehicles, 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 eyelets are 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 Lexus 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-angled objects
•Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle

CAUTION
Caution when using the Lexus parking assist-sensor
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 10 km/h (6 mph).
Do not attach any accessories within the sensor range.
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.

Rear view monitor system
: If equipped
The rear view monitor system assists the driver by displaying an
image of the view behind the vehicle while reversing. The image is
displayed in reverse on the screen. This allows the image to appear in
the same manner as that of the rear view mirror.
The rear view image is dis-
played when the shift posi-
tion is in R and the
“POWER” switch is in ON
mode.
This reversed image is a sim-
ilar image to the one on the
inside rear view mirror.
If you shift the shift position
to any positions other than R,

Driving precautions
When the grade behind the vehicle slopes
up sharply, objects appear to be farther
away than they actually are.
When the grade behind the vehicle slopes
down sharply, objects appear to be closer
than they actually are.

The distance that appears on the screen
between three-dimensional objects (such
as vehicles) and flat surfaces (such as the
road) and the actual distance differ as fol-
lows.
In reality, C = A < B (C and A are equally
far away; B is farther than C and A).
However, on the screen, the situation
appears to be A < B < C.
On the screen, it appears that a truck is
parking about 0.5 m (1.5 ft.) away. How-
ever, in reality if you back up to point A,
you will hit the truck.Approx. 0.5 m (1.5 ft.)
