When the vehicle is not used for a long time, this function extends the interval between each periodic transmission of the request signal, or stops transmission of the request signal to save vehicle battery power.
When the electrical key transmitter sub-assembly is left in a detection area for 10 minutes or more, the smart key system automatically deactivates the exterior detection area the key is in. |

2. DETECTION AREA
NOTICE:
(a) The request signal sent from the certification ECU (smart key ECU assembly) is transmitted from each electrical key antenna (outside) to form the smart key detection area. The detection area formed by each electrical key antenna (outside) has a detection range of 0.7 to 1 m (2.30 to 3.28 ft.) from the door handle.
(b) When the vehicle is parked (the power source mode is off and the doors are locked*), the detection area of each electrical key antenna (outside) is formed by emitting a periodic request signal every 0.25 seconds in order to detect the key. Also, when the doors are locked and a lock sensor is touched, a request signal is emitted, the detection area outside the vehicle is formed and the key is detected.
HINT:
*: The smart key system controls each door individually. After a door is locked with the door lock switch or wireless remote control function, a detection area is formed at the locked door even if all the doors are not locked.
(c) The detection area inside the vehicle is formed and the key is detected when any of the following conditions are met: 1) The driver door is opened and closed, 2) the brake pedal is depressed, 3) the engine switch is operated, 4) the conditions required for various warnings are met, or 5) a entry door lock operation is performed.
(d) The detection area inside the vehicle when starting the engine can be customized through the customize function.
