■Note for the entry function
●Even when the electronic key is within the effective range (detection areas), the system may not operate properly
in the following cases: • The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.• The electronic key is on the instru-
ment panel, luggage cover or floor, or glove box when the engine is started or engine switch modes are changed.
●Do not leave the electronic key on top of the instrument panel when exiting
the vehicle. Depending on the radio wave reception conditions, it may be detected by the antenna outside the
cabin and the door will become lock- able from the outside, possibly trap-
ping the electronic key inside the
vehicle.

the effective range, the doors may be locked or unlocked by anyone. How-ever, only the doors detecting the
electronic key can be used to unlock the vehicle.

to lock the doors when the electronic key is near the vehicle, there is a pos-sibility that the door may not be
unlocked by the entry function. (Use the wireless remote control to unlock the doors.)
●If the door handle becomes wet while the electronic key is within the effec-
tive 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 2 m (6 ft.) or more away from the vehi-
cle. (Take care to ensure that the key is not stolen.)• Set the electronic key to battery-sav-
ing mode to disable the smart entry & start system. ( P.103)
■Note for the unlocking function
●There are cases when pulling the door handle while pressing the Lock/Unlock button that the door will
not unlock. In those cases, after returning the door handle to the origi-nal position, press the Lock/Unlock
button once again and check that the doors unlock before pulling the door handle.
●If there is another electronic key in the detection area, it may take slightly lon-
ger for the doors to unlock after the Lock/Unlock button is pressed.
