■Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent 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. 39) or the mechanical key. ( P. 531)
■ Electronic key battery depletion
● The standard battery life is 1 to 2 years. (The battery becomes depleted
even if the electronic key is not used.) If the smart key system or the
wireless remote control function does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when
necessary. ( P. 461)
● 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
• Recharging cellular phones or cordless phones
• Table lamps
■ To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
the outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or  the door lock prevention may not func-
tion.)

Note for the smart key system
● Even when the electronic key is within the effective range (detection
areas), the system may not operate properly in the following cases.
• The electronic key is too close to the window or outside door handle,
near the ground, or in a high place when the doors are locked or
unlocked.
• The electronic key is near the ground or in a high place, or too close to the rear bumper center when the back door is locked or unlocked.
• The electronic key is on the instrument panel, floor or in the glove box when the engine is started or “ENGINE START STOP” switch modes
are changed.
● As long as the electronic key is within the effective range, the doors may
be locked or unlocked by anyone.
● Even if the electronic key is not inside the vehicle, it may be possible to
start the engine if the electronic key is near the window.
● The doors may unlock if a large amount of water splashes on the door
handle, such as in the rain or in a car wash. (The doors will automatically
be locked after approximately 60 seconds if the doors are not opened
and closed.)
● Gripping the door handle when wearing a glove may not unlock the door.
● If the wireless remote control is used to lock the doors when the elec-
tronic key is near the vehicle, there is a possibility that the door may not
be unlocked by the smart key system. (Use the wireless remote control to
unlock the doors.)
● A sudden approach to the effective range or door handle operation may
prevent the doors from being unlocked.  In this case, return the door han-
dle to the original position and check that the doors unlock before pulling
the door handle.
■ When the vehicle is not dr iven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2
m) of the vehicle.
■ 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.
