Key battery depletion
Vehicles with a smart key system
● 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. 443)
• 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
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
Vehicles without a smart key system
If the wireless remote control function does not operate, the b attery may be
depleted. Replace the battery when necessary. ( P. 443)
■ Precautions when disconnecting the battery (vehicles with a sma rt key
system)
● In some cases, it may not be possible to unlock the doors using the smart
key system immediately after the battery has been disconnected. Use the
wireless remote control or the mechanical key to lock or unlock the doors.
● The engine may not start on the first attempt after reconnectin g the battery
but will start normally after the second attempt. This is not a malfunction.
● The engine switch mode is memorized by the vehicle. When the ba ttery is
reconnected, the system will return to the mode it was in befor e the battery
