1-2. Opening, closing and locking the doors and trunk
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.)
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 unlock before pulling the door handle again.

If a door is not opened within approximately 60 seconds after the vehicle is
