THEFT DETERRENT / KEYLESS ENTRY: SMART KEY SYSTEM (for Start Function): SYSTEM DESCRIPTION

1. SYSTEM FUNCTION





2. DETECTION AREA

NOTICE:
* Depending on the vehicle body shape, the electrical key transmitter sub-assembly may not operate in certain locations.
* Even if the electrical key transmitter sub-assembly is in the vehicle exterior key detection area, the electrical key transmitter sub-assembly may not be properly detected if the electrical key transmitter sub-assembly is near a window, a door handle or the center of the rear bumper.
* Even if the electrical key transmitter sub-assembly is in the vehicle interior key detection area, the electrical key transmitter sub-assembly may not be properly detected if the electrical key transmitter sub-assembly is on the instrument panel, in the glove box or on the floor.
* Depending on the way the electrical key transmitter sub-assembly is held, the electrical key transmitter sub-assembly may not operate properly.
* The key detection area may reduce in size or the electrical key transmitter sub-assembly may not be properly detected under the conditions below:
* The transmitter battery is depleted.
* There are TV towers, electric power plants, broadcasting stations, gas stations or other facilities that produce strong electric waves nearby.
* Wireless products such as cell phones, etc. are carried with the electrical key transmitter sub-assembly.
* The electrical key transmitter sub-assembly is covered by or in contact with a metal object.
* Electric wave-type keyless entry systems are being operated nearby.
* The electrical key transmitter sub-assembly is placed near high-voltage equipment or equipment that emits electrical noise.

(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 handles and rear bumper (electrical key antenna [outside luggage]).

(b) When the vehicle is parked (the power 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 electrical key transmitter sub-assembly. 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 electrical key transmitter sub-assembly 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 of the electrical key antenna (outside luggage) is formed when the luggage door opening switch assembly is pressed.

(d) The detection area inside the vehicle is formed and the electrical key transmitter sub-assembly 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 power switch is operated, 4) the conditions required for various warnings are met, or 5) a smart door lock operation is performed.

(e) The detection area inside the vehicle when starting the hybrid control system can be customized through the customize function Smart Key System (for Start Function).
