lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start and
wireless remote control from operating properly:

■Battery-saving function
In the following circumstances, the entry function is disabled in order to prevent the
vehicle and electronic key batteries from discharging.
●When the entry function has not been used for 2 weeks or more
●When the electronic key has been left within approximately 6 ft. (2 m) of the
vehicle for 10 minutes or more
The system will resume operation when...
●The vehicle is locked using the door handle lock switch.

■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
●If the battery becomes low, an alarm will sound in the cabin when the engine
stops. (→P. 4 6 0 )
●The battery becomes depleted even if the electronic key is not used because
the key always transmits 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. (→P. 4 0 6 )
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of
the following electrical appliances that produce a magnetic field.
•TVs
