Operation of each component
YARIS_F_OM_Europe_OM52A54E●If window tint with a metallic content or metallic objects are attached to the
rear window
●When the electronic key is placed near a battery charger or electronic
devices
■Notes 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 near the ground or in a high place, or too close to
the rear bumper center when the back door is opened.
• The electronic key is on the instrument panel, luggage cover (if equipped)
or floor, or in the door pockets, glove box, accessory box of the instru-
ment panel, or in/near the front cup holder when the engine is started or
engine 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 electronic
key inside the vehicle.
●As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone.
●Even if the electronic key is not inside the vehicle, it may be possible to start
the engine if the electronic key is near the window.
●The doors may unlock if a large amount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the
effective range. (The door will automatically be locked after approximately
30 seconds if the doors are not opened and closed.)
●If the wireless remote control is used to lock the doors when the electronic
key is near the vehicle, there is a possibility that the door may not be
unlocked by the entry function. (Use the wireless remote control to unlock
the doors.)
●Touching the door lock or unlock sensor while wearing gloves may prevent
lock or unlock operation.
●When the lock operation is performed using the lock sensor, recognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
●If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 2 m (6 ft.) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry &
start system. (→P. 170)

■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:
● If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
● Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.
■ After recharging/reconnecting the battery (vehicles with a smart entry &
start system)
● Unlocking the doors using the smart entry & start system may not be possi-
ble immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.
● Start the engine with the engine switch in ACCESSORY mode. The engine
may not start with the engine switch turned off. However, the engine will
operate normally from the second attempt.
● The engine switch mode is recorded by the vehicle. If the battery is recon-
nected, the vehicle will return the engine switch mode to the status it was in
before the battery was disconnected. Make sure to turn off the engine
before disconnect the battery. Take extra care when connecting the battery
if the engine switch mode prior to discharge is unknown.
If the engine will not start even after multiple attempts, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
