ENTRY AND START SYSTEM > SYSTEM DESCRIPTION |
| ENTRY AND START SYSTEM |
In addition to conventional mechanical key and wireless door lock control functions, the entry and start system enables door locking/unlocking, steering lock releasing, engine starting and luggage compartment door opening without operating the key. The only requirement is that the key is in the user's possession.

|
| CONSTRUCTION AND OPERATION |
Key
The key consists of a mechanical key, a transmitter function for the wireless door lock control and a transceiver for the entry and start system.


Oscillator (each door oscillator, front and rear indoor antenna, luggage compartment inner antenna, luggage compartment outer antenna)
Each oscillator transmits the request signal received from the certification ECU, and forms a key detection area to detect the presence of a key. The detection area formed by each door oscillator and luggage compartment outer antenna is approximately 0.7 to 1.0 m (2.3 to 3.3 ft.) from the outside handle of each door or the center of the rear bumper.
| ENTRY FUNCTION OPERATION |
The entry and start system has the following functions.
| Function | Outline |
| Mechanical Key | Operation is same as conventional mechanical key |
| Wireless Door Lock Control | This function remotely locks and unlocks all doors or luggage compartment. Operation is same as wireless door lock control system. However, the receiver in certification ECU uses entry door control receiver to control locking and unlocking. |
| Entry Illumination | When person carrying key enters detection area, door will enter unlock standby mode and front map light and door mirror foot light will illuminate. |
| Entry Unlock | When key is located in detection area of door oscillator, door will unlock by touching inside of outside door handle. |
| Entry Unlock Mode Switching (Click here ) | Changes doors that can be unlocked with entry unlock function between 4 modes.
|
| Entry Lock | When key is located in detection area of door oscillator and engine switch is off, door can be locked by pressing lock switch on outside door handle. |
| Entry Luggage Compartment Open | When key is in detection area of luggage compartment outer oscillator, luggage compartment opens by pressing luggage compartment open switch. |
| Memory Call | This function operates driving position memory system in accordance with key ID code. |
| Key Lock-in Prevention |
|
| Warning | When any of situations below occur, entry and start system causes certification ECU to sound buzzer in combination meter and wireless door lock buzzer, and illuminate the key warning light in order to alert driver.
|
| Battery Saving | If key is constantly located within detection area of door oscillator, system maintains periodic communication with key. Therefore, if vehicle remains parked in that state for long time, key battery and vehicle battery could be drained. |
| Key Cancel (Click here) | Following key functions can be canceled by following certain operations.
|
| WIRELESS DOOR LOCK AND UNLOCK AND LUGGAGE COMPARTMENT OPEN FUNCTION |
| ENTRY UNLOCK FUNCTION |
The detection area is formed by communication between a door oscillator and tuner when the door is locked in order to detect access of the person carrying the key.
When the person carrying the key enters the detection area around the vehicle, the matching of the ID codes for a door oscillator and key will automatically be performed. After the matching is completed, the door will enter unlock standby mode.
In unlock standby mode, the antenna built into the outside handle starts sensing. If the outside handle is held (the back side of the handle is touched), the door unlock operation will be performed. At this time, the hazard warning lights blink twice and the wireless door lock buzzer sounds twice.
If any of the doors are not opened after a door unlock operation, all doors will automatically lock after 30 seconds.
| ENTRY LOCK FUNCTION |
After leaving the vehicle carrying the key, push the lock switch on the outside handle when all the doors are closed.
The certification ECU determines whether the key is located inside or outside of the cabin based on the information from a door oscillator and room oscillator. Then matching of the ID codes is performed.
When the matching result shows that the ID codes of the key and indoor antenna do not match and the ID codes of the key and door oscillator match, the door lock function will operate. At this time, the hazard warning lights blink once and the wireless door lock buzzer sounds once.
If the key is located inside of the cabin, the door lock function will not operate and the alarm buzzer (beep sound) will sound for 2 seconds.
| ENTRY LUGGAGE COMPARTMENT OPEN FUNCTION |
| PREVENTION OF KEY CONFINEMENT FUNCTION |
If you attempt to lock the door through keyless operation (move the lock knob to the lock position and then close the door) with the key in the cabin, the system determines that the key is located in the cabin and unlocks the door.
If the luggage compartment is closed with the key in it, the alarm will sound and the luggage compartment can be opened only when all the doors are locked in order to prevent key confinement in the vehicle.
| ENTRY ILLUMINATION FUNCTION |
| MEMORY CALL FUNCTION |
| WARNING FUNCTION |

| BATTERY SAVING |
Vehicle Battery Saving Function
In the entry and start system, signals are emitted outside of the vehicle at a prescribed interval (0.25 seconds) when the doors are locked. Therefore, the vehicle battery could be drained if the vehicle remains parked for a long time. For this reason, the controls listed below are affected.
| Condition | Control |
Both conditions below are met for 5 days:
| Signal transmission interval is extended from 0.25 to 0.75 seconds |
Both conditions below are met for 14 days:
| Automatically deactivates the entry and start system |
Key Battery and Vehicle Battery Saving Function
In the entry and start system, if the key is constantly located within the vehicle exterior detection area of the doors, 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 battery could be drained. For this reason, if this state continues longer than 10 minutes, the entry and start system automatically becomes deactivated.
