[When the engine was started using the key] If the driver’s door is opened when the key is in the “LOCK” or “ACC” position or removed from the ignition switch while the lamps are on, a buzzer will sound to remind the driver to turn off the lamps.

[When the engine was started using the keyless operation function] If, while the lamps are illuminated, the ignition switch is set to the “LOCK” or “ACC” position, or the driver’s door is opened with the ignition switch set to the “LOCK” position, a buzzer will sound to remind the driver to turn off the lamps.

In both cases, the buzzer will automatically stop if the auto-cutoff function is activated, the lamp switch is turned off, or the door is closed.
