■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 near the ground or in a high place, or too close to the rear bumper center when the trunk is unlocked.
• The electronic key is on the instrument panel, rear package tray or floor, or in the door pockets or glove box when the hybrid system is started or
“POWER” switch modes are changed.
●As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone.
●Even if the electronic key is not inside th e vehicle, it may be possible to start the
hybrid system if the electronic key is near the window.
●The doors may unlock if a large amount of water splashes on the door handle,
such as in the rain or in a car wash when the electronic key is within the effective
range. (The door will automatically be locked after approximately 60 seconds if
the doors are not opened and closed.)
●Gripping the door handle when wearing a glove may not unlock the door.
●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 re mote control to unlock the doors.)
●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.
■Notes for locking the doors
●Touching the door lock sensor while we aring gloves may delay or prevent lock
operation. Remove the gloves and touch the lock sensor again.
●When the lock operation is performed using the lock sensor, recognition signals
will be shown up to two consecutive times. After this, no recognition signals will
be given.
●If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. Place the key in a position 6 ft.
(2 m) or more separate from the vehicle while the vehicle is being washed. (Take
care to ensure that the key is not stolen.)

depleted even if the electronic key is not used. The following symptoms indicate
that the electronic key battery may be depleted. Replace the battery when nec-
essary. (P. 4 5 3 )
• The smart access system with push-bu tton start or the wireless remote con-
trol does not operate.
