vehicle and electronic key batteries from discharging.

●
When the electronic key has been left within approximately 3 ft. (1 m) of the
●
vehicle for 10 minutes or more
The system will resume operation when...
The vehicle is locked using the door handle lock switch.

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 engine
●
stops. (P. 41)
The battery becomes depleted even if the electronic key is not used because
●
the key always transmits radio waves. If the smart access system with push-but-
ton start or the wireless remote control function does not operate, or the detec-
tion area becomes smaller, the battery may be depleted. Replace the battery
when necessary. (P. 606)
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
