Security System

Immobilizer System

The immobilizer system prevents a key that has not been pre-registered from starting the engine. Each key contains electronic transmitters that use electronic signals to verify the key.

Pay attention to the following when inserting the key into the ignition switch or pressing the ENGINE START/STOP button:

Do not allow objects that emit strong radio waves near the ignition switch or the

ENGINE START/STOP button.

Make sure the key is not covered by or touching a metal object.

Do not bring a key from another vehicle’s immobilizer system near the ignition switch or the ENGINE START/STOP button.

Do not put the key near magnetic items. Electronic devices, such as televisions and audio systems emit strong magnetic fields. Note that even a key chain can become magnetic.

The security system alarm activates when the trunk, hood or doors are forcibly opened. The alarm does not activate if the trunk or doors are opened with the key, remote transmitter or smart entry system*.

However, the alarm activates if a door is opened with the key and then the transmission is taken out of (continuously variable transmission models) or the hood is opened before the ignition switch is turned to ON w*1.

*1: Models with the smart entry system have an ENGINE START/STOP button instead of an ignition switch.

* Not available on all models
