■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.
●Do not leave the electronic key on top of the instrument panel or near the door
pockets when exiting the vehicle. Depending on the radio wave reception con-
ditions, it may be detected by the antenna outside the cabin and the door will
become lockable from the outside, possibly trapping the electronic key inside
the vehicle.
●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 the 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 remote 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.

■To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get the
electronic key too close to the vehicle when operating the system from the outside
of the vehicle.
Depending on the position and holding condition of the electronic key, the key may
not be detected correctly and the system may not operate properly. (The alarm may
go off accidentally, or the door lock prevention may not operate.)

■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year
and a half.)
●If the battery becomes low, an alarm will sound in the cabin when the hybrid sys-
tem stops. ( →P. 5 2 4 )
●As the electronic key always receives radio waves, the battery will become
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 6 7 )
• The smart access system with push-button start or the wireless remote con- trol does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
