If the key is in close proximity to or touching a key to the security system
(key with a built-in transponder chip) of another vehicle

Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise
When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
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
When carrying 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 computers or personal digital assistants (PDAs)

cle with the engine switch in ACCESSORY or IGNITION ON mode for long
periods of time when the engine is not running.
