Function to prevent the trunk being locked with the electronic key inside: When all doors are locked, closing the trunk lid with the electronic key left inside the trunk will sound an alarm. In this case, the trunk lid can be opened by pressing the trunk release button on the trunk lid. If the spare electronic key is put in the trunk with all the doors locked, the key confinement prevention function is activated so the trunk can be opened.
In order to prevent theft, take all electronic keys with you when leaving the vehicle. If the electronic key is put in the trunk with all the doors locked, the key may not be detected depending on the location of the key and the surrounding radio wave conditions. In this case, the key confinement prevention function cannot be activated, causing the doors to lock when the trunk is closed.
Make sure to check where the key is before closing the trunk. The key confinement prevention function cannot be activated if any one of the doors is unlocked. In this case, open the trunk using the trunk opener switch.
