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

Conditions which may affect the rear view monitor system
If the back of the vehicle has been hit, the camera’s position and mounting
angle may have been changed. Have the vehicle inspected by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
Rapid temperature changes, such as when hot water is poured on the vehi-
cle in cold weather, may cause the system to function abnormally.
If the camera lens is dirty, it cannot transmit a clear image. Rinse with
water and wipe with a soft cloth. If the camera lens is extremely dirty,
wash with a mild cleanser and rinse.

distorted when the system is cold.
When washing the vehicle, do not apply intensive bursts of water to the
camera or camera area. Doing so may result in the camera malfunctioning.
Do not allow organic solvent, car wax, window cleaner or glass coat to
adhere to the camera. If this happens, wipe it off as soon as possible.
As the camera has a water proof construction, do not detach, disassemble
or modify it. This may cause incorrect operation.
Do not hit the camera or subject it to strong impacts as this may cause its
position and mounting angle to change.
Do not scrub the camera lens roughly or clean it with a hard brush or abra-
sive cleaner. Doing so may damage the lens and adversely affect the
