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. (

●

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. (

To operate the system properly

Make sure to carry the electronic key when operating the system. Do not get the

electronic key too close to the vehicle when operating the system from the outside

of the vehicle.

Depending on the position and holding condition of the electronic key, the key may

not be detected correctly and the system may not operate properly. (The alarm may

go off accidentally, or the door lock prevention may not function.)
