Conditions affecting operation

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 on the instrument panel, floor or in the glove box 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 reception 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. However, only the doors detecting the electronic key can be used to unlock the vehicle.
  • The doors may unlock or lock 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 approximately 60 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 smart key system. (Use the wireless remote control to unlock the doors.)
  • If power slide door is unable to operate due to prohibition by the power sliding door main switch, the door unlock and open operation will not be performed.

Note for locking the doors

  • Touching the door lock sensor while wearing gloves may delay or prevent lock operation. Remove the gloves and touch the lock sensor again.
  • When the lock operation is performed using the lock sensor, recognition signals 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 effective range, the door may lock and unlock repeatedly. Place the key in a position 6 ft. (2 m) or more separate from the vehicle while the vehicle is being washed. (Take care to ensure that the key is not stolen.)
  • If the electronic key is inside the vehicle and a door handle becomes wet during a car wash, a message may be shown on the multi-information display and a buzzer will sound outside the vehicle. To turn off the alarm, lock all the doors.
  • The lock sensor may not work properly if it comes into contact with ice, snow, mud, etc. Clean the lock sensor and attempt to operate it again, or use the lock sensor on the lower part of the door handle.
  • Fingernails may scrape against the door during operation of the door handle.

    Be careful not to injure fingernails or damage the surface of the door.

Notes for the unlocking function

  • Gripping the front door handle when wearing a glove may not unlock or lock the door.
  • A sudden approach to the effective range or door handle operation may prevent the doors from being unlocked. In this case, return the door handle to the original position and check that the doors have unlocked before pulling the door handle.
  • If there is another electronic key in the detection area, it may take slightly longer to unlock the doors after one of the front door handles is gripped or one of sliding door handles is pulled.

When the vehicle is not driven for extended periods

  • To prevent theft of the vehicle, do not leave the electronic key within 6 ft.
(2 m) of the vehicle.
  • The smart key system can be deactivated in advance.

    • 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 vehicle 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 key system does not operate properly

    • Locking and unlocking the doors: Use the mechanical key.
    • Starting the engine

    WARNING

    Caution regarding interference with electronic devices

    • People with implantable cardiac pacemakers, cardiac resynchronization therapy-pacemakers or implantable cardioverter defibrillators should keep away from the smart key system antennas. The radio waves may affect the operation of such devices. If necessary, the entry function can be disabled. Ask your Toyota dealer for details, such as the frequency of radio waves and timing of the emitted radio waves.

      Then, consult your doctor to see if you should disable the entry function.

    • Users of any electrical medical device other than implantable cardiac pacemakers, cardiac resynchronization therapy-pacemakers or implantable cardioverter defibrillators should consult the manufacturer of the device for information about its operation under the influence of radio waves. Radio waves could have unexpected effects on the operation of such medical devices.

    Ask your Toyota dealer for details for disabling the entry function.
