■Battery-saving function
The battery-saving function will be activated in order to prevent the electronic key
battery and the vehicle battery from being discharged while the vehicle is not in
operation for a long time.
●In the following situations, the smart access system with pu sh-button start may
take some time to unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of the
outside of the vehicle for 10 minutes or longer.
• The smart access system with push-button start has not been used for 5 days
or longer.
●If the smart access system with push-but ton start has not been used for 14 days
or longer, the doors cannot be unlocked at any doors except the driver’s door. 
In this case, take hold of the driver’s door handle, or use the wireless remote
control or the mechanical key, to unlock the doors.
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication betw een electronic key and the vehicle may
be affected, preventing the smart access system with push-button start and wireless
remote control from operating properly. (Way of coping: P. 7 3 8 )
