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 becomes low, an alarm will sound in the cabin when the engine
stops. (

P. 483)
●
The battery becomes depleted even if the electronic key is not used because
the key always receives radio waves. If the smart access system with push-but-
ton start or the wireless remote control does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary. (
