ENTRY AND START SYSTEM SYSTEM DESCRIPTION

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, steering lock releasing, hybrid control system starting and luggage compartment door opening 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. When the certification ECU detects the presence of the key 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 7 oscillators and 1 antenna (4 door oscillators, 1 luggage compartment antenna, 1 luggage compartment oscillator, and 2 indoor oscillators).

COMMUNICATION FREQUENCY BETWEEN KEY AND VEHICLE

DETECTION AREA

1. Precautions for the entire system:

   
   

   • Be sure to carry the key during inspection of the entry and start system.

   • As weak radio waves are used to detect the key, the key detection area may decrease, or the key may not be detected correctly in the following situations:

   
   

   1. The key battery is depleted.

   2. Any facilities that generate strong radio waves, such as a TV tower, power plant, portable media players, broadcast station or gas station, are located near the inspection site.

   3. A wireless device, such as a cellular phone, is carried with the key.

   4. The key is in contact with or covered with metal.

   5. Another wireless door lock control function is operated near the vehicle.

   6. The key is located near a device that generates high voltage or noise.

   
   

   • The key may be difficult to operate for a reason relating to the vehicle body shape.

   • The key may not be detected correctly if it is around the vehicle's windows, the door handle or center of the bumper, even when it is in the detection area outside the vehicle.

   • The key may not be detected correctly if it is on the instrument panel, rear package tray or floor, or in the glove box, even when it is in the detection area inside the vehicle.

   • The hybrid control system cannot be started even when the key is in the detection area inside the luggage compartment.

   • The key may not operate if the key is not held properly.

   • The entry and start system does not operate in the following conditions:

   
   

   1. The entry and start system is canceled.

   2. The key battery is completely depleted (the indicator does not blink when pushing any of the buttons on the key).

WIRELESS DOOR LOCK AND UNLOCK AND LUGGAGE COMPARTMENT OPEN FUNCTION

Push the LOCK/UNLOCK/PANIC*/LUGGAGE COMPARTMENT switch on the key to operate each function.

ENTRY UNLOCK FUNCTION

1. The detection area is formed by communication between a door oscillator and the certification ECU when the door is locked in order to detect the person carrying the key.

2. 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.

3. 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 light blinks twice and the wireless door lock buzzer* sounds twice.

   Tech Tips

   *: except Europe and China

4. If any of the doors are not opened after a door unlock operation, all doors will automatically lock after 30 seconds.

ENTRY LOCK FUNCTION

1. After leaving the vehicle carrying the key, push the lock switch on the outside handle when all the doors are closed.

2. The certification ECU determines whether the key is located inside or outside of the cabin based on the information from a door oscillator and indoor oscillator. Then matching of the ID codes is performed.

3. When the matching result shows that the ID codes of the key and indoor oscillator 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.

   Tech Tips

   *: except Europe and China

4. 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.

BATTERY SAVING

1. Vehicle auxiliary 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 auxiliary battery could be drained if the vehicle remains parked for a long time. For this reason, the controls listed below exist.

   Condition	Control
   Both conditions below are met for 10 days: Key is not in detection area Touch sensor or lock switch operation is not performed	Signal transmission interval is extended from 0.25 to 0.75 seconds
   Both conditions below are met for 15 days: Key is not in detection area Touch sensor or lock switch operation is not performed	Signal transmission interval is extended from 0.75 to 2.25 seconds
   Both conditions below are met for 30 days: Key is not in detection area Touch sensor or lock switch operation is not performed	Automatically deactivates the entry and start system

   Reinstatement Conditions:

   
   

   • A wireless door lock control signal (lock, unlock) is input and the ID matches.

   • A user carries the key and pushes a lock switch on an outside door handle.

   • The driver door is locked or unlocked by the mechanical key.

2. Key battery and vehicle auxiliary 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 auxiliary battery could be drained. For this reason, if this state continues longer than 10 minutes, the entry and start system automatically becomes deactivated.

   Reinstatement Conditions

   
   

   • A wireless door lock control signal (lock, unlock) is input and the ID code matches.

   • A user carries the key and pushes a lock switch on an outside handle.

   • The driver door is locked or unlocked by the mechanical key.
