continuously
■Battery-saving function
The battery-saving function will be
activated in order to prevent the

12-volt battery from being dis-
charged while the vehicle is not
operated for a long time.
●In the following situations, the
smart key system may take some
time to unlock the doors.
• The electronic key has been left in
an area of approximately 6 ft. (2
