when the electronic key is to not  
be used for long periods of time,  
set the electronic key to the bat-  
tery-saving mode. (P.205)

lowing symptoms indicate that the  
electronic key battery may be  
depleted. Replace the battery  
when necessary.

mended to not stay with the elec-  
tronic key near the vehicle longer
