Sensor detection information ●
Certain vehicle conditions and the su rrounding 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 sensor s 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 (low ered 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 judg ed 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 materi als that absorb sound waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projec ting outwards in the direction of your
vehicle

Flicker effect
When the camera is used under fluorescent light, sodium lights, or mercury lights
etc., the lights and the illuminated areas may appear to flicker.
CAUTION■
When using the rear view monitor system, observe the following precautions to
avoid an accident that could result in death or serious injuries: ●
Never depend solely on the monitor system when reversing.●
Always check visually and with the mirrors to confirm your intended path is clear.●
Use your own eyes to confirm the vehicle’s surroundings, as the displayed image
may become faint or dark, and moving imag es will be distorted, or not entirely
visible when the outside temperature is low. When backing up, be sure to check
behind and all around the vehicle visually and with the mirrors before proceeding.●
Always check the vehicle surrounding area, because the guide lines are ancillary
lines.●
The guide lines are ancillary lines and do not change even if the steering wheel is
turned.●
Depicted distances between objects and flat surfaces differ from actual dis-
tances.●
Do not use the system if the back door is open.
