●
If the key is inside the vehicle while it is being washed, water applied to a
door handle may cause a buzzer to sound. In this event, locking all doors
will cause the buzzer to stop sounding.
● It may not be possible to lock the doors if the sensor area is covered by
mud, ice, snow etc. In this event, try locking again after cleaning the
area, or lock by touching the sensor area on the underside 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.
● Gripping the door handle when wearing a glove may not unlock or lock
the door.
● If the wireless remote control is used to lock the doors when the elec-
tronic 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.)
● 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 unlock before pulling
the door handle again.
● 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.
■ 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.
(2 m) of the vehicle.
● The smart key system can be deactivated in advance. ( P. 587)
