Engine Start/Stop Switch
Pressing the engine start/stop button changes the vehicle mode from OFF (LOCK), ACCESSORY, ON, or START mode. The engine start/stop switch also includes an LF antenna. When operating the backup function, the engine start/stop switch receives the immobilizer signal from the remote, and sends an immobilizer signal to the body control module.
LF (Low Frequency) Antennas
The front interior, middle interior, rear interior, left/right-front, left/right-rear *, and rear bumper LF antennas send the signals to the remote inside and outside of the vehicle.

Remote
The remote is equipped with a keyless transmitter, and all the 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 body control module. After receiving authentication, the body control module controls the door lock/unlock actuator.
Tailgate Outer Handle Lock Switch
The tailgate outer handle lock switch is built in the tailgate outer handle. To operate the door locks without the built-in key while carrying the remote, press the tailgate outer handle lock switch to lock the doors.
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.

The keyless buzzer located inside the rear bumper sounds when smart entry functions or alarm function.
