3-1. Key information
■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press
any buttons on the electronic key while inside the aircraft cab in. If you are
carrying an electronic key in your bag etc., ensure that the bu ttons are not
likely to be pressed accidentally. Pressing a button may cause the electronic
key to emit radio waves that could interfere with the operation of the aircraft.
■ 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 wh en the engine
stops.
● As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. ( P. 499)
• The smart key system or the wireless remote control does not o perate.
• 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 magnet ic field:
•TVs
• Personal computers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
■ Replacing the key battery

■Battery-saving function
The battery-saving function will be activated in order to preve nt the electronic
key battery and the battery from being discharged while the veh icle is not in
operation for a long time.
● In the following situations, the smart key system may take some time to
unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of
the outside of the vehicle for 10 minutes or longer.
• The smart key system has not been used for 5 days or longer.

cannot be unlocked at any doors except the driver’s door. In th is case, take
hold of the driver’s door handle, or use the wireless remote co ntrol or the
mechanical key, to unlock the doors.
■ Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping
the electronic key from receiving radio waves.
■ Conditions affecting operation
The smart key system uses weak radio waves. In the following si tuations, the
communication between the electronic key and the vehicle may be affected,
preventing the smart key system, wireless remote control and en gine immobi-
lizer system from operating properly.
(Ways of coping:  P. 560)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio stati on, large dis-
play, airport or other facility that generates strong radio wav es or electrical
noise
● 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 other wireless keys (that emit radio waves) are being used nearby
Press twice while pressing and hold-
ing . Confirm that the electronic key
indicator flashes 4 times.
