■Security feature
If a door is not opened within approximately 60 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again. 
■ Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle battery from discharging and the electronic key battery from
depleting.
● When the entry function has not been used for 5 days or more
● When the electronic key has been left within approximately 6 ft. (2 m) of
the vehicle for 10 minutes or more
● If the entry function has not been used for 14 days or more, the vehicle
cannot be unlocked by a door other than the driver's door. To unlock the
vehicle, grip the driver's door handle or use the wireless remote control
or the mechanical key.
The system will resume operation when
● The vehicle is locked using the door handle lock switch when carrying the

■Electronic key battery depletion
● The standard battery life is 1 to 2 years.
● As the electronic key always transmits 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 necessary. ( P. 528)
• The smart key system or the wireless remote control 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
■ Precautions when disc onnecting the battery
● In some cases, it may not be possible to unlock the doors using the smart
key system immediately after the battery has been disconnected. Use
the wireless remote control or the mechanical key to lock or unlock the
doors.
● The engine may not start on the first attempt after reconnecting the bat-
tery but will start normally after the second attempt. This is not a malfunc-
tion.
● The “ENGINE START STOP” switch mode is memorized by the vehicle.
When the battery is reconnected, the system will return to the mode it
was in before the battery was disconnected. Before disconnecting the
battery, turn the “ENGINE START STOP” switch off.
If you are unsure what mode the “ENGINE START STOP” switch was in
when the battery was disconnected, be especially careful when reconnect-
ing the battery.
