Conditions aff ecting operation
The smart key system uses weak radio waves. In the following situations,
the communication between the electronic key and the vehicle may be
affected, preventing the smart key system and wireless remote control from
operating properly. (Ways of coping P. 400)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electri-
cal noise
● When carrying a portable radio, ce llular phone, cordless phone or other
wireless communication device
● When the electronic key is in contact with, or is covered by the following
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
• A wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)

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. 38)
● 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 necessary. ( P. 326)
• The smart key system or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
● 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
• Recharging cellular phones or cordless phones
• Cellular phones, cordless phones and battery chargers

long periods of time when the engine is not running.
Vehicles with a manual transmission
If the vehicle is left in ACCESSORY or IGNITION ON mode (the engine is
not running) for more than an hour, the “ENGINE START STOP” switch will
automatically turn off. However, this function cannot entirely prevent battery

in ACCESSORY or IGNITION ON mode for long periods of time when the
engine is not running.
■ Operation of the “ENG INE START STOP” switch
When operating the “ENGINE START STOP” switch, one short, firm press is
