■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.
●To avoid serious deterioration, do not leave the electronic key within 1 m (3
ft.) of the following electrical appli- ances that produce a magnetic field:•TVs
• Personal computers • Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cord- less phones• Table lamps
• Induction cookers

■Note for the entry function
●Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the
window or outside door handle, near the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is on the instru- ment panel, luggage room, floor, or in the door pockets or glove box when
the EV system is started or power switch modes are changed.
●Do not leave the electronic key on top of the instrument panel or near the door pockets when exiting the vehicle.
Depending on the radio wave recep- tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the elec-tronic key inside the vehicle.
●As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. How- ever, only the doors detecting the electronic key can be used to unlock
the vehicle.
●Even if the electronic key is not inside
the vehicle, it may be possible to start the EV system if the electronic key is near the window.

handle, such as in the rain or in a car wash when the electronic key is within the effective range. (The doors will
automatically be locked after approxi- mately 30 seconds if the doors are not opened and closed.)

nals will be shown up to two consecu- tive times. After this, no recognition signals will be given.
●If the wireless remote control is used to lock the doors when the electronic
key is near the vehicle, there is a pos- sibility that the door may not be unlocked by the entry function. (Use
the wireless remote control to unlock the doors.)
