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

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
