• The transmitter is integrated into the master key.

• There are two buttons on the transmitter; the lock button and the unlock button.

• When either button is pressed, the transmitter emits a radio signal representing a specific ID code.

• An indicator lamp, which illuminates when signals are transmitted, is added on the key grip. This indicator lamp informs you of the signal transmission status and warns you of flat battery.

• A brilliant silver Three-diamond mark is stamped on the back side of the key grip to improve appearance.

• A signal transmission circuit (printed circuit) and a battery are housed in one case. The case is housed in the key grip, thus improving resistance to water ingress.

• A coin type battery, CR1616 is used in the transmitter.

• The transmitter button operation allows the system to operate as follows:

<EXCEPT VEHICLES FOR HONG KONG SPEC>

Operation of keyless entry system	Operation of transmitter
Lock all doors and tailgate	Lock button (pressed once)
Unlocks all doors and tailgate	Unlock button (pressed once)

<VEHICLES FOR HONG KONG SPEC>

The keyless entry system is activated	The transmitter is operated
All doors (including the tailgate) are locked. NOTE: If the retracting function of the electric folding mirrors is added as an adjustment function, it can be retracted in synchronism with a lock operation.	Press the lock button once.
All doors (including the tailgate) are unlocked. NOTE: If the extending function of the electrical folding mirrors is added as an adjustment function, it can be extended in synchronism with an unlock operation.	Press the unlock button once.
Fully close the power windows and sunroof. NOTE: The fully closing operation of the power windows and sunroof can be switched on/off as an adjustment function.	Press the lock button once to lock all doors (including the tailgate), and within 30 seconds press and hold the lock button for 1 second or longer.
Fully open the power windows (only for front windows). NOTE: The fully opening operation of the power windows (only for front windows) can be set as an adjustment function.	Press the unlock button once to unlock all doors (including the tailgate), and within 30 seconds press and hold the unlock button for 1 second or longer.
The door mirrors are retracted.	Press the lock button once to lock all doors (including the tailgate), and within 30 seconds press the lock button twice quickly.
The door mirrors return to the original position.	Press the unlock button once to unlock all doors, and within 30 seconds press the unlock button twice quickly.

The figure at the left shows the codes transmitted from the transmitter. Every time the button is pressed, the data code is transmitted twice. The secret code for user identification is a combination of 0 and 1, and more than 1 million different combinations are available. In addition to the secret code, the data code contains a rolling code which changes at each transmission, protecting transmission codes from theft by coping.

• The ETACS-ECU incorporates a receiver with an antenna. The receiver compares the code sent from the transmitter with the code retained in the receiver through the antenna.

• The ETACS-ECU sends a signal only when those two codes correspond and the rolling code is judged correct.

• All of those output signals are processed internally in the ETACS-ECU.

• A maximum of four cipher code (4 transmitters) can be registered by connecting the diagnosis connector to the MUT-II/III.

When the ETACS-ECU (receiver) sends a signal to the door lock actuators and tailgate lock actuator, the turn-signal lamps and room lamp illuminate, indicating that the keyless entry system is activated.
The turn-signal lamp answerback can be switched between "lock/unlock yes", "lock only yes", "unlock only yes" and "none" with the adjustment function*. This feature is factory preset (default) to "lock/unlock yes".

Item	Operation
	Doors and tailgate locked	Doors and tailgate unlocked
ETACS-ECU (receiver)	Sends lock signal	Sends unlock signal
Room lamp	Flashes twice	Illuminates for 15 seconds
Hazard warning lamp	Flashes twice	Flashes once

• The ETACS-ECU (receiver) sends a door lock signal automatically unless any door is opened within 30 seconds after the doors have been unlocked by the keyless entry system while all doors are closed.

• This function prevents the doors unlocked unintentionally.

If any door (including the tailgate) is not opened or closed within 30 seconds after the doors (including the tailgate) are unlocked by the keyless entry system, ETACS-ECU automatically outputs the door lock signal to lock the doors (including the tailgate). This function prevents the doors (including the tailgate) from being unlocked unexpectedly by operation errors.

• The timer lock time can be changed by 30, 60, 120, or 180 seconds with the adjustment function*. The initial timer lock time at factory is set to 30 seconds <Vehicles for Hong Kong spec>.
NOTE: *: The timer lock time can be changed as an adjustment function (Refer to GROUP 54B, SMART WIRING SYSTEM ).

The operation of the keyless entry system is inhibited in the following conditions.

• When the ignition key is inserted into the ignition switch.

• When either door (including the tailgate) is open (the door switch: ON) (including door ajar).

The security alarm function is premised on the door lock operation by the transmitter of the keyless entry system. The function warns when the doors (including the tailgate) are opened by any operation other than the keyless entry system. The security alarm setting can be changed to "Active: Horn and hazard warning lamp are used for alarm (*1)" "Active: Only hazard warning lamp is used for alarm (*2)" or "Inactive (*3)". The initial setting at factory is "Inactive" (Refer to GROUP 54B, SMART WIRING SYSTEM ).
This adjustment function is described on the instruction manual to help customers adjust.

• The security alarm sticker is stored in the glovebox.

• Advise your customers to affix the security alarm sticker onto the quarter window glasses or similar place from outside the vehicle. Never affix this sticker onto the windshield, front door glasses, or other places where driver's view may be obstructed by the sticker.
NOTE: If it is affixed onto a glass which can be opened or closed, it may be peeled off.

The security indicator lamp is installed on the center panel of the instrument panel.

The bonnet switch is installed in the engine compartment. The bonnet switch detects that the bonnet is opened, and sends the signal to the ETACS-ECU.
