■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

rear window
●When the electronic key is placed
near a battery charger or electronic devices
●When the vehicle is parked in a pay parking spot where radio waves are emitted
■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.
●The doors may unlock if a large amount of water splashes on the door
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.)
●When the lock operation is performed using the lock sensor, recognition sig-
nals will be shown up to two consecu- tive times. After this, no recognition signals will be given.

during a car wash, a message may be shown on the multi-information dis-play and a buzzer will sound outside
the vehicle. To turn off the alarm, lock all the doors.
●The lock sensor may not work prop-erly if it comes into contact with ice, snow, mud, etc. Clean the lock sensor
and attempt to operate it again.
●A sudden approach to the effective
range or door handle may prevent the doors from being unlocked. In this case, return the door handle to the
original position and check that the doors unlock before pulling the door handle again.
●If there is another electronic key in the detection area, it may take slightly lon-
ger to unlock the doors after the door handle is gripped.
■When the vehicle is not driven for extended periods
●To prevent theft of the vehicle, do not leave the electronic key within 2 m (6
ft.) of the vehicle.
●The smart entry & start system can be
deactivated in advance.
●Setting the electronic key to battery-
saving mode helps to reduce key bat- tery depletion. ( P.204)
■To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get the electronic key too close to the vehi-
cle when operating the system from the outside of the vehicle.
Depending on the position and holding
condition of the electronic key, the key may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the door lock prevention may not operate.)
■If the smart entry & start system does not operate properly
