■ Battery-saving function
In the following circumstances, the entry function is disabled in order to prevent the
vehicle and electronic key batteries from discharging.
● When the entry function has not been used for 2 weeks or more
● 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.
● The vehicle is locked/unlocked using the wireless remote control function
(P. 49) or the mechanical key. (P. 872)
■ 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. 44)
● The battery becomes depleted even if the electronic key is not used because
the key always receives 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. 784)
● 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
• Induction cookers
•Table lamps
