Electronic key battery depletion
■
The standard battery life is 1 to 2 years. (The card key battery life is about a year
●
and a half.)
If the battery becomes low, an alarm will sound in the cabin when the hybrid sys-
●
tem stops. (P. 622)
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. (P. 556)
• The smart access system with push-button start or the wireless remote con-
trol 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
• Glass top ranges
• Table lamps
