CAUTION■
Caution regarding interference with electronic devices ●
People with implantable cardiac pacemakers, cardiac resynchronization therapy-
pacemakers or implantable cardioverter de fibrillators should keep away from the
smart access system antennas. (  P. 5 9 )
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 the emitte d radio waves. Then, consult your doctor
to see if you should disable the entry function.●
User of any electrical medical device other than implantable cardiac pacemak-
ers, cardiac resynchronization therapy-pacemakers or implantable cardioverter
defibrillators should consult the manufacturer of the device for information about
its operation under the influence of radio waves.
Radio waves could have unexpected effe cts on the operation of such medical
devices.
Ask your Lexus dealer for disabling the entry function.

Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice and plas-
tic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canc eled if an obstruction is detected.
■
Warning lights, messages and buzzer s for dynamic radar cruise control
Warning lights, messages and buzzers are us ed to indicate a system malfunction or
to inform the driver of the need for caution while driving. (  P. 74 8 )■

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

Reception sensitivity ●
Cargo loaded on the roof luggage carrier, especially metal objects, may
adversely affect the reception of XM ®
Satellite Radio.●
It is difficult to maintain perfect radio re ception at all times due to the continually
changing position of the an tenna, differences in signal strength and surrounding
objects, such as trains and transmitters.●
The radio antenna is mounted inside th e rear spoiler and 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.■

CAUTION■
FCC WARNING
Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
This equipment complies with FCC/IC radiation exposure limits set forth for an
uncontrolled environment and meets the FCC radio frequency (RF) Exposure
Guidelines in Supplement C to OET65 and RSS-102 of the IC radio frequency
(RF) Exposure rules. 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 operated keeping the radiator at least 20
cm or more away from person’s body (excluding extremities: hands, wrists, feet and
ankles).
Cet équipement est conforme aux limites d’exposition aux rayonnements énon-
cées pour un environnement non contrôlé et respecte les règles les radioélec-
triques (RF) de la FCC lignes directrice s d’exposition dans le Supplément C à
OET65 et d’exposition aux fréquences ra dioélectriques (RF) CNR-102 de l’IC.
Cet équipement émet une énergie RF très faible qui est considérée conforme sans
évaluation de l’exposition maximale autorisée.
Cependant, cet équipement doit être insta llé et utilisé en gardant une distance de
20 cm ou plus entre le dispositif rayonnan t et le corps (à l’exception des extrémités
: mains, poignets, pieds et chevilles).
This transmitter must not be co-located or operated in conjunction with any other
antenna or transmitter.
Under Industry Canada regulations, this radio transmitter may only operate using
an antenna of a type and maximum (or lesser) gain approved for the transmitter by
Industry Canada. To reduce potential radio interference to other users, the antenna
type and its gain should be so chosen that the equivalent isotropically radiated
power (e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d’Indu strie Canada, le présent émetteur radio
peut fonctionner avec une an tenne d’un type et d’un gain maximal (ou inférieur)
approuvé pour l’émetteur par Industrie Ca nada. Dans le but de réduire les risques
de brouillage radioélectrique à l’intention des autres utilisateurs, il faut choisir le
type d’antenne et son gain de sorte que la puissance isotrope rayonnée équivalente
(p.i.r.e.) ne dépasse pas l’intensité nécessaire à l’établissement d’une communica-
tion satisfaisante.

Caution regarding interference with electronic devices ●
Your audio unit is fi tted with Bluetooth ®
antennas. People with implantable car-
diac pacemakers, cardiac resynchronization therapy-pacemakers or implantable
cardioverter defibrillators should maintain a reasonable distance between them-
selves and the Bluetooth ®
antennas. The radio waves may affect the operation of
such devices.●
Before using Bluetooth ®
devices, users of any electrical medical device other
than implantable cardiac pacemakers, cardiac resynchronization therapy-pace-
makers or implantable cardioverter defibrillators should consult the manufac-
turer 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.
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.
