tronic key battery and the vehicle battery from being discharged while the
vehicle is not in operation for a long time.
In the following situations, the smart entry & start system may take some
time to unlock the doors.
• The electronic key has been left in an area of approximately 2 m (6 ft.)
of the outside of the vehicle for 10 minutes or longer.

Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situ-
ations, the communication between the electronic key and the vehicle may
be affected, preventing the smart entry & start system, wireless remote con-
trol and engine immobilizer system from operating properly.
(Way of coping: P. 619)
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

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

munication device
• Another vehicle’s electronic key or a wireless key that emits radio
waves
