Keyless Entry: Description and Operation

GENERAL INFORMATION

NOTE: In this manual, F.A.S.T.-key (Free-hand Advanced Security Transmitter) is described as Keyless Operation System (KOS).

The Keyless Operation System (KOS) enables the driver to unlock all the doors* and the liftgate by just pulling the front door outside handle or operating the liftgate lock release handle, without taking the key out from his/her pocket or bag when he/she is carrying a Keyless Operation Key which has been registered in the vehicle's KOS-ECU. KOS also allows the driver to lock all the doors and the liftgate by pressing the lock switch on the front door outside handle or on the liftgate lock release handle (door entry function), and start the engine without using the conventional mechanical key (engine start function). KOS has the following features:

- The keyless operation key incorporates the lock and unlock switches on it. Like the conventional keyless entry system, remote control operation can be performed by using these switches. The keyless operation key also incorporates an indicator light that enables the driver to check if the signal is transmitted correctly or if the battery in the key is discharged.
- The keyless operation Key incorporates the immobilizer function that inhibits starting the engine by using an unauthorized key.
- The incorporated TPMS function monitors the air pressure of all the tires.
- Each vehicle is provided with two keyless operation keys. Up to four keyless operation keys can be registered in the vehicle's KOS-ECU.
- The keyless operation key incorporates an emergency key with a transponder to lock/unlock the doors and start the engine in case the battery in the keyless operation key is discharged or the Keyless Operation System is not working normally. The driver can customize KOS; enabling/disabling all the system functions, enabling the door locking/unlocking function only, or enabling the engine starting function only.

NOTE: When the driver's front door outside handle is operated, only the driver's door is unlocked.
