■Note for locking the doors
●To u c h i n g   t h e   d o o r   l o c k   s e n s o r   w h i l e   w e a r i n g   g l o v e s   m a y   d e l a y   o r   p r e v e n t
lock operation. Remove the gloves and touch the lock sensor again.
●When the lock operation is performed using  the  lock sensor, recognition
signals will be shown up to two consecutive times. After this, no recogni-
tion signals will be given. 
●If  the  door  handle  becomes  wet  while  the  electronic  key  is  within  the
effective  range,  the  door  may  lock  and  unlock  repeatedly.  Place  the  key
in a position 6 ft. (2 m) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
●If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a buzzer will sound outside the vehicle. To turn off the
alarm, lock all the doors.
●The  lock  sensor  may  not  work  properly  if  it  comes  into  contact  with  ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again, or
use the lock sensor on the lower part of the door handle.
●Fingernails  may  scrape  against  the  door  during  operation  of  the  door
handle.  Be  careful  not  to  injure  fingernails  or  damage  the  surface  of  the
door.

■If the smart key system does not operate properly
●Locking and unlocking the doors: Use the mechanical key. ( oP.   5 9 9 )
●Starting the hybri d system:  oP.   6 0 0
■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
hybrid system stops. ( oP.   1 1 8 )
●As  the  electronic  key  always  receives  radio  waves,  the  battery  will
become  depleted  even  if  the  electronic  key  is  not  used.  The  following
symptoms  indicate  that  the  electronic  key  battery  may  be  depleted.
Replace the battery when necessary. ( oP.   4 9 7 )
•The smart key system or the wireless remote control does not operate.
•The detection area becomes smaller.
•The LED indicator on the key surface does not turn on.
