■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year and
a half.)
●If the battery is low, an alarm will sound in the cabin when the engine is started or
stopped. ( P. 158)
●The battery becomes depleted even if the electronic key is not used because the
key always receives radio waves. If the smart entry & start system or the wireless
remote control does not operate, or the detection area becomes smaller, the bat-
tery may be depleted. Replace the battery when necessary. ( P. 575)
