General Description Ignition key reminder tone alarm
The ignition key reminder tone alarm will sound under the following condition, and warn the driver to remove the ignition key.
- The driver's door is opened when the ignition switch is at "OFF" or "ACC" position without removing the ignition key.
However, the light reminder torn alarm will take precedence over this function.
Immobilizer system
The immobilizer system consists of the ignition key, the key ring antenna, the immobilizer-ECU, and the PCM. The ignition key has a built-in transponder. The key ring antenna is installed on the steering lock key cylinder. Only the registered ignition key permits the engine to start, therefore, the engine can never be started by means of a forged key or by connecting the ignition wiring directly. The system is significantly safe and reliable against theft. In addition, the driver has only to turn the ignition switch to the ON position to activate the immobilizer system. If the requirements for starting the engine are not satisfied, the engine will be immobilized, and "SECURITY" indicator light will flash for thirty seconds. If the ignition key is lost or another ignition key is added, the encrypted code can be registered or erased by using scan tool MB991502. In addition, if the transponder built-in key is lost, the override function will mobilize the engine temporarily. (For the override function, consult with the service center.)
