CAUTION
■Caution regarding interference with electronic devices
●People with implanted pacemakers or cardiac defibrillators should keep away
from the smart access system antennas. (P. 3 0 )
The radio waves may affect the operation of such devices. If necessary, the entry
function can be disabled. Ask your Lexus dealer for details, such as the frequency
of radio waves and timing of emitting the radio waves. Then, consult your doctor
to see if you should disable the entry function.
●User of any electrical medical device other than implanted pacemakers and
implanted cardiac defibrillators should consult the manufacturer of the device for
information about its operation under the influence of radio waves.
Radio waves could have unexpected effects on the operation of such medical
devices.
Ask your Lexus dealer for details for disabling the entry function.

■Sensor detection information
●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.
• The sensor is frozen.
• 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
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 particu-
lar attention to the following obstacles.
• Wires, fences, ropes etc.
• Cotton, snow and other materials that absorb radio waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your
vehicle

3-2. Using the audio system
■When the battery is disconnected
Station presets are erased.
■Reception sensitivity
●Maintaining perfect radio reception at all times is difficult due to the continually
changing position of the antenna, differences in signal strength and surrounding
objects, such as trains, transmitters, etc.
●The radio antenna is mounted inside the rear window. To maintain clear radio
reception, do not attach metallic window tinting or other metallic objects to the
antenna wire mounted inside the rear window.

■Certifications for the radio tuner
This equipment has been tested and found to comply with the limits for a class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installa-
tion. This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful inter-
ference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encour-
aged to try to correct the interference by trying one or more of the following:
●Reorienting or relocate the receiving antenna.
●Increasing the separation between the equipment and receiver.
●Connecting the equipment into an outlet on a circuit different from that to which
the receiver is connected.
●Consulting the dealer or an experienced radio/TV technician for help.
“CH UNAVL”
The channel you selected is no longer available. Wait
for about 2 seconds until the radio returns to the previ-
ous channel or “CH001”. If it does not change auto-
matically, select another channel.

Radio Frequency Radiation Exposure. This equipment complies with FCC radiation
exposure limits set forth for uncontrolled equipment and meets the FCC radio fre-
quency (RF) Exposure Guidelines in Supplement C to OET65. This equipment has
very low levels of RF energy that it deemed to comply without maximum permissive
exposure evaluation (MPE). But it is desirable that it should be installed and oper-
ated with at least 7.9 in. (20 cm) and more between the radiator and person’s body
(excluding extremities: hands, wrists, feet and ankles).
This transmitter must not be co-located or operated in conjunction with any other
antenna or transmitter.
■Caution while driving
Do not connect portable players or operate the controls.
NOTICE
■To prevent damage to portable players
Do not leave portable players in the vehicle. The temperature inside the vehicle
may become high, resulting in damage to the player.
