1-2. Opening, closing and locking the doors and trunk
■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 a month 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. 44)
●The vehicle is locked/unlocked using the mechanical key. ( P. 5 3 3 )
■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. 5 1 4 )
●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 does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary. (  P. 4 5 6 )
●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

1-2. Opening, closing and locking the doors and trunk
●If the wireless remote control is used to lock the doors when the electronic key
is near the vehicle, there is a possibility that the door may not be unlocked by the
entry function. (Use the wireless re mote 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 handle to the original
position and check that the doors unlock before pulling the door handle again.
■When the vehicle is not driven 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 approx imately 60 seconds after the vehicle is
unlocked, the anti-theft system automatically locks the vehicle again.
■Alarms and warning indicators
A combination of exterior and interior alarms as well as warnings displayed on the
multi-information display are used to prevent theft of the vehicle and unforeseeable
accidents resulting from erroneous operation. Take appropriate measures in
response to any warning indications on the multi-information display. ( P. 5 0 4 )
