Immobilizer

The immobilizer is a start inhibitor that helps prevent unauthorized persons from starting the engine.

Each of the keys supplied with your vehicle contains a unique coded transponder. The vehicle code in the key is transmitted to the vehicle's ignition system where it is compared to the code stored in the start inhibitor module.

The following message (which may appear in the instrument panel) is related to the immobilizer:
