ENTRY AND START SYSTEM (for Entry Function) SYSTEM DESCRIPTION

CAUTION:

If using a pacemaker, be sure to read the manual of the pacemaker before using the key, as the radio waves of the key may affect the pacemaker.

ENTRY AND START SYSTEM DESCRIPTION
1. In addition to conventional mechanical key and wireless door lock control functions, the entry and start system enables door locking/unlocking and hybrid control system starting without operating the key. The only requirement is that the key is in the user's possession.
  - This system is controlled by the certification ECU (smart key ECU assembly). When the certification ECU (smart key ECU assembly) detects the presence of the entry and start system in one of the detection areas, it identifies and checks the ID code, and outputs operation signals to the related ECU in accordance with their functions.
  - The detection areas are formed by 6 oscillators (2 door oscillators, 1 outside oscillator and 3 indoor oscillators).

DETECTION AREA

w/ Entry System Back Door Open Function

Actuation Area	Detail
Interior	The interior detection area of the indoor electrical key oscillators (for front, center and rear floor) is formed when the driver door is opened or closed, when the power switch is pushed, when a warning is activated, or when the lock sensor on the door outside handle assembly or lock switch on the back door opener switch assembly is on.
Exterior	The exterior detection area formed by the door electrical key oscillators (for driver side and front passenger side) and outside electrical key oscillator (for rear side) is approximately 0.7 to 1.0 m (2.30 to 3.28 ft.) from the door outside handle assembly of the front doors, or the center of the rear bumper.
Around Front Door	The exterior detection area of the door electrical key oscillator (for driver side or front passenger side) is formed by transmitting a request signal every 0.25 seconds while the power switch is off and each door is locked. In this way it detects the proximity of a key. When locking the door using the lock sensor on the door outside handle assembly, the detection area is formed when the lock sensor is touched.
Around Back Door	The exterior detection area of the outside electrical key oscillator (for rear side) is formed by when the back door opener switch assembly (opener or lock switch) is on.

CONSTRUCTION AND OPERATION

Key

The key consists of a mechanical key, transmitter for wireless door lock control and transceiver for the entry and start system.

The transceiver function for the entry and start system receives the signals from the oscillators and sends the ID code to the tuner.
The transmitter function for the wireless door lock control has a lock switch, unlock switch and remote A/C switch.
The mechanical key works for the driver door and glove box, but cannot start the hybrid control system.

A total of 7 keys can be registered.

*3	Remote A/C Switch	*4	Mechanical Key

Oscillator (door electrical key oscillator (for driver side and front passenger side*), indoor electrical key oscillator (for front, center and rear floors) and outside electrical key oscillator (for rear side)*)

Each oscillator transmits the request signal received from the certification ECU (smart key ECU assembly), and forms a key detection area to detect the presence of a key. The detection area formed by door electrical key oscillator (for driver side and front passenger side*) and outside electrical key oscillator (for rear side*) is approximately 0.7 to 1.0 m (2.30 to 3.28 ft.) from the door outside handle assembly of door (for driver side, front passenger side*) or the center of the rear bumper.
- The detection area of the door electrical key oscillators (for driver side and front passenger side*) is formed by transmitting a request signal periodically while the power switch is off and the doors (for driver side and front passenger side*) are locked. In this way, the oscillator detects the proximity of a key. During entry lock, the detection area is formed with the lock sensor on.
- The detection area of the outside electrical key oscillator (for rear side) is formed when the back door opener switch assembly (opener or lock switch) is on.*
- The detection area of the indoor electrical key oscillators (for front, center and rear floor) is formed when any door is opened or closed, during hybrid control system start, when a warning is activated, or when the lock sensor on the door outside handle assembly or lock switch on the back door opener switch assembly is on.

ENTRY FUNCTION OPERATION

The entry and start system has the following functions:

Function	Outline
Wireless Door Lock Control	This function is a convenient system for locking and unlocking all the doors and back door at a distance. The operation of this function is the same as that in the wireless door lock control system.
Entry Unlock	When a key is in the exterior detection area of any door electrical key oscillator, the door will unlock after the inner side of front door outside handle assembly (for driver side or front passenger side*) is touched.
Entry Lock	When a key is in the exterior detection area of a door electrical key oscillator (driver side or front passenger side) and the power switch is off, all doors can be locked by simply touching the lock sensor on the door outside handle assembly. When a key is in the exterior detection area of the outside electrical key oscillator (for rear side) and the power switch is off, all doors can be locked by simply pressing the lock switch on the back door opener switch assembly.
Entry System Back Door Open Function*	When a key is in the exterior detection area of the outside electrical key oscillator (for rear side), the back door opens manually by simply pressing the back door opener switch assembly (opener switch).
Prevention of Key Confinement	The key confinement prevention function prevents the vehicle from being locked with a key left inside.
Warning	When any of the situations below occurs, the entry and start system causes the each ECU to sound the buzzer in the combination meter assembly and wireless door lock buzzer, and indicate a warning on the multi-information display in order to alert the driver: The hybrid control system is left running and the shift lever is in R, N, D or B when the driver gets out of the vehicle. The key reminder sounds. The hybrid control system is left running and park (P) is selected when the driver gets out of the vehicle. A door is ajar. The hybrid control system is left running when a passenger gets out of the vehicle while holding the key. The key is not in the detection areas. The key is left in the vehicle. The key battery is weak. The power management control ECU is malfunctioning. The hybrid control system cannot be started (driver error). The hybrid control system cannot be started (system error). An attempt is made to turn off the vehicle with the shift lever in R, D or B. Auto power off operation occurs. Immobiliser system certification completion occurs. The vehicle is driven without a key.
Battery Saving	If the key remains within the exterior detection area of any electrical key oscillator (for driver, front passenger or rear side), the system maintains periodic communication with the key. Therefore, if the vehicle remains parked in that state for a long time, the key battery and the vehicle auxiliary battery could be drained.
Key Cancel Click here	The following key functions can be canceled by following certain procedures: Entry Unlock/Lock Entry Hybrid Control System Start Entry System Back Door Open Function* Key Lock-in Prevention Warning
Key Code Registration	A total of 7 keys can be registered. This function enables the registration (writing and storing) of transmitter recognition codes in the EEPROM that is contained in the certification ECU (smart key ECU assembly).
