■When riding in an aircraft
When bringing an electronic key onto an
aircraft, make sure you do not press any buttons on the electronic key while inside the aircraft cabin. If you are carry-
ing an electronic key in your bag, etc., ensure that the buttons are not likely to be pressed accidentally. Pressing a but-
ton may cause the electronic key to emit radio waves that could interfere with the operation of the aircraft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
●If the battery becomes low, an alarm will sound in the cabin when the EV
system stops.
●To reduce key battery depletion when the electronic key is to not be used for
long periods of time, set the electronic key to the battery-saving mode. ( P.204)
●As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indicate that the electronic key battery
may be depleted. Replace the battery when necessary. ( P.499) • The smart entry & start system or the
wireless remote control does not oper- ate.• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
You can replace the battery by yourself
( P.499). However, as there is a danger that the electronic key may be dam-aged, it is recommended that replace-
ment be carried out by any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.

ft.) of the following electrical appli- ances that produce a magnetic field:•TVs
