WARNING
Certain vehicle functions may be
affected by interference from high-fre-
quency radio signals. Such signals
originate from various transmitter sys-
tems, for example, from air traffic bea-
cons or relay stations for mobile
telecommunications.
We recommend you consult any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer should you experience any
difficulties in this regard.

WARNING
There is a possibility of reciprocal
interference between the vehicle elec-
tronics and mobile radio devices.
Radiation is generated when mobile
radio devices are transmitting. There
is a danger of injury or damage to
property. If possible, only use mobile
radio devices, for example mobile
telephones, in the interior if they are
connected directly to an external
antenna in order to eliminate recipro-
cal interference and to dissipate the
radiation from vehicle's interior.
