NOTE:
When ignition key warning chime and light warning chime should be performed at the same time, the priorities
for each chime are the following.
1. Light warning chime
2. Ignition key warning chime
IGNITION KEY WARNING CHIME (WITHOUT INTELLIGENT KEY)
With the key inserted into the ignition switch, and the ignition switch OFF or ACC, when driver's door open, the
warning chime will sound.
Power is supplied
