■Battery-saving function
In the following circumstances, the entry function is disabled in order to prevent the
12-volt battery from discharging and the electronic key battery from depleting.
●When the entry function has not been used for 30 days or more
●When the electronic key has been left within approximately 6 ft. (2 m) of the vehi-
cle for 10 minutes or more
The system will resume operation when
●The vehicle is locked using the door handle lock switch when carrying the elec-
tronic key on your person.
●The vehicle is locked/unlocked using the wireless remote control function.
( P. 141)
●The vehicle is locked/unlocked using the mechanical key. ( P. 5 2 4 )

■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the follow-
ing situations, the communication between the electronic key and the vehicle may be
affected, preventing the smar t access system with push-button start, wireless remote
control and immobilizer system from operating properly. (Ways of coping: P. 5 2 4 )
●When the electronic ke y battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, air-
port or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wireless
communication device
●When the electronic key is in contact with, or is covered by the following metallic
objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When multiple electronic keys are in the vicinity
●When other wireless keys (that emit radio waves) are being used nearby
●When carrying the electronic key togeth er with the following devices that emit
radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or person al digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or metallic objects are attached to the rear
window

■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 opened.
• The electronic key is on the instrument pa nel, 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 condi-
tions, it may be detected by the ante nna 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. However, only th e doors detecting the electronic key can
be used to unlock the vehicle.
●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 doors 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 rang e 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 befo re pulling the door handle again.

■When the vehicle is not driven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2 m) of the
vehicle.
■Alarm
Using the smart access system with push-but ton start to lock the doors will set the
alarm system. ( P. 9 0 )
■To operate the system properly
●Make sure to carry the electronic key wh en operating the system. Do not get the
electronic key too close to the vehicle wh en operating the system from the outside
of the vehicle.
Depending on the position and holding co ndition 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 function may not oper-
ate.)
●Do not leave the electronic key inside the trunk.
The key confinement prevention function may not operate, depending on the loca-
tion of the key (close to a spare tire, the in side edge of the trunk), conditions (inside
a metal bag, close to metallic objects) and the radio waves in the surrounding area.
( P. 151)
■If the smart access system with push-button start does not operate properly
●Locking and unlocking the doors and trunk: Use the mechanical key. ( P. 5 2 4 )
●Starting the hybrid system: P. 5 2 6

■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 is low, an alarm will sound in the cabin when the hybrid system is
started or stopped. ( P. 1 3 0 )
●The battery becomes depleted even if the electronic key is not used because the
key always receives radio waves. If the smart access system with push-button start
or the wireless remote control does not operate, or the detection area becomes
smaller, the battery may be depleted. Replace the battery when necessary.
( P. 4 7 2 )
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of
the following electrical appliances that produce a magnetic field:
•TVs
•Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
•Table lamps
• Induction cookers
■When the electronic key battery is fully depleted

■Customization
Settings (e. g. smart access system with push-button start) can be changed.
