Battery-saving function
The battery-saving function will be activated in order to prevent the electronic key bat-
tery and the battery from being discharged wh ile the vehicle is not in operation for a long
time. ●
In the following situations, the smart access system with push-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-butto n start has not been used for 5 days or
longer. ●

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 us e the wireless remote control or the mechan-
ical key, to unlock the doors. ■
Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
The smart access system with push-button start uses weak radio waves. In the following
situations, the communication between th e electronic key and the vehicle may be
affected, preventing the smart access system with push-button start, wireless remote
control and engine immobilizer system from operating properly.
(Ways of coping:  P. 5 5 0 )●
