Actuation Area	Detail
Interior	The interior actuation area of the indoor electrical key antennas (front, rear) is formed when the driver door is opened or closed, when the power switch is pushed, when a warning is activated, or when an entry lock operation is performed.
Inside Luggage Compartment	The inside luggage compartment actuation area is formed when the luggage compartment door is closed after the doors are locked or before any doors are opened after the doors are unlocked.
Exterior	The exterior actuation area formed by the door electrical key antennas (LH, RH) and outside electrical key antenna is approximately 0.7 to 1.0 m (2.3 to 3.3 ft.) from the flush handle or the center of the rear bumper.
Around Front Doors	The exterior actuation area of the door electrical key antennas 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 presence of an electrical key transmitter sub-assembly. When a door is locked by an entry lock operation, the actuation area is formed.
Around Luggage Compartment Door	The exterior actuation area of the electrical key antenna is formed when all the doors are locked and the luggage electrical key switch is on.

FUNCTION

The entry and start system consists of the following functions:

Function	Outline
Entry Unlock	Allows the door to be unlocked when the depression on the front end of a retracted flush handle is pressed while the electrical key transmitter sub-assembly is carried. When the driver flush handle is operated, only the driver door unlocks. (Driver Door Unlock Mode) When the driver flush handle is operated, all the doors unlock. (All Door Unlock Mode) When the passenger flush handle is operated, all the doors unlock.
Entry Unlock Mode Switching	Allows switching between 2 modes that can be operated with the entry unlock function. Driver Door Unlock Mode All Door Unlock Mode
Entry Lock	Allows all the doors to be locked when the rear end of an extended flush handle is pressed while the electrical key transmitter sub-assembly is carried.
Luggage Compartment Door Open	When an electrical key transmitter sub-assembly is in the exterior actuation area of the outside electrical key antenna (luggage compartment door), the luggage compartment door opens manually by simply pushing the luggage electrical key switch.
Start	Changes the power source or starts the hybrid system.
Answer Back	When the doors are being locked or unlocked by the entry function, the wireless door lock buzzer sounds* and the hazard warning lights blink once while locking and twice while unlocking. Also, the answer back function operates when the doors are locked by the automatic relock function.
Power Switch Lettering Illumination Indication	Indicates the power source change condition and that the hybrid system start conditions are met by flashing and illuminating the power switch lettering.
Door Open Operation Prohibition	Prohibits the use of entry lock operations to lock the door when any door is ajar or open.
Warning	When any of the situations below occur, the entry and start system causes the certification ECU to sound the buzzer in the combination meter and the wireless door lock buzzer, and indicates a warning on the multi-information display in order to alert the driver. An exit warning is activated if the shift position is in any position other than P. An exit warning is activated if the shift position is in P and the power switch is in a mode other than off. A warning is activated if the occupant accidentally leaves with the electrical key transmitter sub-assembly. A warning is activated if the power switch is operated while the electrical key transmitter sub-assembly is outside the actuation area. A warning is activated if the lock switch is operated while the electrical key transmitter sub-assembly is inside the vehicle. A warning is activated if the key battery is weak.
Prevention of Key Confinement	Prevents the vehicle from being locked with an electrical key transmitter sub-assembly left inside it.
Prevention of Key Confinement into Luggage Compartment	Allows the luggage electrical key switch to be pressed and used to open the luggage compartment door when the luggage compartment door is closed with the electrical key transmitter sub-assembly inside the luggage compartment, even though the luggage compartment door cannot normally be opened in that condition.
Battery Saving	Suppresses auxiliary battery level drops when the vehicle is not used for a long period of time by extending the interval between or stopping each periodic transmission of the request signal and restricting the entry function. When the electrical key transmitter sub-assembly is in an exterior actuation area for approximately 10 minutes or more, periodic transmission of the request signal is stopped to suppress electrical key transmitter sub-assembly battery level drops. Puts the electrical key transmitter sub-assembly in the sleep condition to suppress electrical key transmitter sub-assembly battery level drops. When the unlock switch is pressed 2 times while pressing the lock switch of the electrical key transmitter sub-assembly, the electrical key transmitter sub-assembly stops waiting on standby to receive electrical waves, suppressing electrical key transmitter sub-assembly battery level drops.
