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 han-
dle 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 dr iven for extended periods
● To prevent theft of the vehicle, do not leave the electronic key within 6 ft.
