To reduce key battery depletion when the
●
electronic key is to not be used for long
periods of time, set the electronic key to
the battery-saving mode. (P.113)
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 nec-
essary.
• The smart access system with push-but-
ton start or the wireless remote control
does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface
does not turn on.
To avoid serious deterioration, do not
●
leave the electronic key within 3 ft. (1 m)
of the following electrical appliances that
produce a magnetic field:
• TVs
• Personal computers
• Cellular phones, cordless phones and
battery chargers
• Recharging cellular phones or cordless
phones
• Table lamps
• Induction cookers
■ Replacing the battery

■
tered keys
