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 is low, an alarm will sound in the cabin when the engine is started or
●
stopped. (P. 158)
The battery becomes depleted even if the electronic key is not used because the
●
key always receives radio waves. If the smart entry & start system or the wireless
remote control does not operate, or the detection area becomes smaller, the bat-
tery may be depleted. Replace the battery when necessary. (P. 575)
To avoid serious deterioration, do not leave the electronic key within 1 m (3 ft.) 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
