How does the engine immobilizer work?

The engine won’t start on if the key hasn’t been registered with the computer on the vehicle.

Engines without a smart key system

The indicator light is located on the center display and will flash after the key has been taken out of the ignition. The light stops flashing when a programed key is put back into the ignition.

Engines with a smart key system

When the Engine Start Stop switch has been shut off, the indicator light will flash. It stops once the switch is turned back on.

Tip

Don’t leave keys inside a vehicle when you exit.
