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 nec-
essary. ( P.349) • The smart entry & start system or the wireless remote control does not oper-
ate. • The detection area becomes smaller.• The LED indicator on the key surface
does not turn on.
