Engine Start/Stop Switch
Pressing the engine start/stop switch changes the vehicle mode to OFF (LOCK), ACCESSORY, ON, or START mode. The engine start/stop switch also includes an LF antenna. When the backup function operating, the engine start/stop switch receives the immobilizer signal from the remote, and sends immobilizer signal to the keyless access/TPMS control unit.
RF (Radio Frequency) Unit
The RF unit is located on the rear shelf. It receives signals from the remote.
LF (Low Frequency) Antennas
The front interior, rear interior, left/right-front, and left/right-rear LF antennas send the signals to the remote inside and outside of the vehicle.

Remote (Without Remote Engine Start System)
The remote is equipped with a keyless transmitter and all doors can be locked and unlocked by a lock/unlock button operation even from a remote distance from the vehicle. When the lock button or unlock button is pressed, the keyless transmitter sends the applicable switch signal to the keyless access/TPMS control unit. After receiving authentication from the keyless access/TPMS control unit, the door lock/unlock signals are sent to the MICU through the B-CAN.
Bi-Directional Remote (With Remote Engine Start System)
The bi-directional remote transmitter uses long range and short range communication with the vehicle. Long range communication is used only for locking the doors and the remote engine start function. The bi-directional remote transmitter contains one coin cell battery and one rechargeable battery. The rechargeable battery is used for long-range operation and is recharged automatically from the coin cell battery. Three LEDs are used to indicate status of bi-directional remote transmitter and remote engine start system operation.
