Electronic key battery depletion

tem stops. (

●

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. (
