Battery-saving function
In the following circumstances, the entry func tion 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 th e door handle lock switch.●
The vehicle is locked/unlocked using the wireless remote control function
( P. 48) or the mechanical key. ( P. 8 6 7 )■
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. 4 3 )●
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. 7 8 0 )●

the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
