■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.
●If the door handle becomes wet while the electronic key is within the effective
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 6 ft. (2 m) 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 access sys-
tem with push-button start. (P. 1 1 3 )
●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.
■Note for the unlocking function
●A sudden approach to the effective range or door handle 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.
●Gripping the door handle when wearing a glove may not unlock the door.
●If the door handle becomes wet while the electronic key is within the effective
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 6 ft. (2 m) 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 access sys-
tem with push-button start. (P. 1 1 3 )
●If there is another electronic key in the detection area, it may take slightly longer to
unlock the doors after the door handle is gripped.

Operation of each component
■Trunk easy closer (vehicles with power trunk opener and closer)
In the event that the trunk lid is left slightly open, the trunk easy closer will automati-
cally close it to the fully closed position.
■Function to prevent the trunk being locked with the electronic key inside
●When all doors are being 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 pressing the trunk release button on the
trunk lid.
●Even when the spare electronic key is put in the trunk with all the doors locked, the
key confinement prevention function can be activated so the trunk can be opened.
In order to prevent theft, take all electronic keys with you when leaving the vehicle.
●Even when the electronic key is put in the trunk with all the doors are locked, the
key may not be detected depending on the places and the surrounding radio wave
conditions. In this case, the key confinement prevention function cannot be acti-
vated, causing the doors to lock when the trunk is closed. Make sure to check
where the key is before closing the trunk.

doors is unlocked. In this case, open the trunk using the trunk opener.
