Operation signals
Doors: The emergency flashers flash to indicate that the doors have been
locked/unlocked. (Locked: Once; Unlocked: Twice)
Windows and moon roof: A buzzer sounds to indicate that the windows and
moon roof are operating.
Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following sit-
uations, the communication between the electronic key and the vehicle may
be affected, preventing the smart entry & start system and wireless remote
control from operating properly:
(Ways of coping: P. 516)
When the electronic key battery is depleted
Near a TV tower, electric power plant, gas station, radio station, large
display, airport or other facility that generates strong radio waves or elec-
trical noise
When carrying a portable radio, cellular phone, cordless phone or other
wireless communication devices
When the electronic key is in contact with, or is covered by the follow-
ing 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 another wireless key (that emits radio waves) is being used nearby
When carrying or using the electronic key together with the following
devices that emit radio waves
• Another vehicle's electronic key or a wireless key that emits radio
waves
• Personal computer or personal digital assistant (PDA)
• Digital audio player
• Portable game system
If window tint with a metallic content or metallic objects are attached to
the rear window

Switching the door unlock function
It is possible to set which doors the entry function unlocks.
Turn the “ENGINE START STOP” switch OFF.
Cancel the intrusion sensor of the alarm system to prevent unin-
tended triggering of the alarm during the setting change. (P. 1 0 2 )
When the indicator on the key surface is turned off, push and
hold or for approximately 5 seconds while pushing
on the key.
The setting changes each time an operation is performed, as shown below.
(When changing the setting continuously, release the buttons, wait for at
least 5 seconds, and repeat step 3.)
To prevent unintended triggering of the alarm, unlock the doors using the
electronic key and open and close a door once after the settings have been
changed. (If a door is not opened within 30 seconds after is pressed, the
doors will be locked again and the alarm will automatically be set.)
In case that the alarm is triggered, immediately stop the alarm. (P. 102)

Battery-saving function
In the following circumstances, the entry function is disabled in order to
prevent the vehicle and electronic key batteries from discharging.
When the entry function has not been used for a month or more
When the electronic key has been left within approximately 1 m (3 ft.) of
the vehicle for 10 minutes or more
The system will resume operation when
The vehicle is locked using the door handle lock switch.
The vehicle is locked/unlocked using the wireless remote control func-
tion.
(P. 55)
The vehicle is locked/unlocked using the mechanical key. (P. 516)
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
engine stops. (P. 481)
The battery becomes depleted even if the electronic key is not used
because the key always receives radio waves. If the smart entry & start
system 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. 431)
To avoid serious deterioration, do not leave the electronic key within 1 m
(3 ft.) 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
• Glass top ranges
• Table lamps

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
function.)
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 glove box when the engine is started or “ENGINE
START STOP” 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 conditions, 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 engine 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. (The doors will automatically
be locked after approximately 30 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 elec-
tronic 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 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.
