1. Turn the main switch to “ON” with the code re-registering key.
NOTE:
Check that the immobilizer system indicator light comes on for one second, then goes off. When the
immobilizer system indicator light goes off, the code re-registering key has been registered.
2. Check that the engine can be started.
3. Register the standard key, following the instructions in the section below.
Standby mode:
To enable the immobilizer system, turn the ignition key to “OFF”. 30 seconds later, the indicator light
will start flashing continuously in the standby flashing mode pattern for up to 24 hours. After that
time, the indicator light will stop flashing, but the immobilizer system is still enabled.
