have been locked/unlocked. (Locked: Once; Unlocked: Twice)
Trunk: A buzzer sounds to indicate that the trunk has been unlocked.
Windows and standard moon roof: A buzzer sounds to indicate that the windows

door is made. Fully close the door to stop the buzzer, and lock the vehicle once
more.
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start and
wireless remote control from operating properly:

(Ways of coping: →P. 4 7 7)
●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 electrical noise
●When carrying a portable radio, mobile phone, cordless phone or other wire-
less communication devices
●When the electronic key is in contact with, or is covered by the following metal-
lic 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

■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 2 weeks or more
●When the electronic key has been left within approximately 6 ft. (2 m) 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 function.
(→P. 3 8 )
●The vehicle is locked/unlocked using the mechanical key. (→P. 4 7 7 )
■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
●If the battery becomes low, an alarm will sound in the cabin when the engine
stops. (→P. 4 6 0 )
●The battery becomes depleted even if the electronic key is not used because
the key always transmits radio waves. If the smart access system with push-but-
ton start or the wireless remote control does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary. (→P. 4 0 6 )
●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
• Mobile phones, cordless phones and battery chargers
• Recharging mobile phones or cordless phones
•Glass top ranges

■To operate the system properly

electronic key too close to the vehicle when operating the system from the outside
