  1. T1: 20+/- min.
SEAT BELT WARNING TIMER
1. Since the ignition is switched ON, the seat belt warning indicator is illuminated (with period: 0.6 sec., duty rate: 50%) and the chime bell is sounded (with period: 0.9 sec., duty rate: 50%) for total time 6 seconds.
2. If the ignition is switched off during the indicator and the chime bell output, the indicator and the chime bell are switched OFF.
  If the seat belt is sensed as fastened during the indicator and the chime bell output, the chime bell is switched OFF immediately and the seat belt warning indicator is illuminated for the remained time.
3. When the ignition is already switched ON, if the seat belt is removed, the warning indicator and the chime bell are output for total time 6 seconds.

  1. T1: 6+/-1sec., T2: 0.45+/-0.1 sec.,
  2. T3: 0.3+/-0.1 sec.
DECAYED ROOM LAMP & KEYLESS UNLOCK TIMER
1. When the first door (driver's or assist) is opened, the room lamp shall brighten. When the last door is closed, the room lamp will drop to 75% intensity, then fade out over 5-6 seconds.
2. If the door switch is ON for less than 0.1 sec., then no illumination occurs.
3. The fade resolution is over 32 steps.
4. The room lamp must not flicker during fade operation, if the ignition is switched ON.
5. With keyless UNLOCK, when the door is closed, the room lamp is turned ON, then OFF after about 30 seconds. While the room lamp is ON due to keyless UNLOCK, if another UNLOCK is received, the room lamp is again ON for 30 seconds.
  While the room lamp is ON, If the door is opened, the lamp is continued to ON. If the door is closed, the lamp follows as the above step 1.
  
  If keyless LOCK (ARM state) is received during fade out, the room lamp is switched off immediately.

  1. T1: 5.5+/-0.5 sec., T2: 30+/-3 sec.
DOOR OPEN WARNING
1. If the key is in the ignition key cylinder and the driver's door is opened, the chime bell sounds continually (period: 0.9 sec. Duty rate: 50%).
2. If the door is closed or the key is removed, the chime stops immediately.

  1. T1, T2: 0.45+/-0.1 sec.
TAIL LAMP AUTO CUT
1. When the tail lamp is switched ON, if the ignition key switch is OFF and the driver's door is opened, the tail lamp should be automatically OFF.
2. With the ignition key switch ON, if the driver's door is opened and the ignition key switch is OFF, the tail lamp should be automatically OFF.
3. When the tail lamp is cut automatically, if the tail lamp switch is turned OFF and ON, the tail lamp is illuminated and auto cut function is cancelled.

IGNITION KEY HOLE ILLUMINATION
1. Ignition key hole illumination is turned on when door is opened (at ignition switch "OFF").
2. Delaying "ON" state of ignition key hole illumination for 10 sec. when the door is closed in case of No. 1) state.
3. The ignition key hole illumination is turned off if the ignition input is accepted in case of No. 1), 2) state.
4. The ignition key hole illumination is turned OFF if arm state is entered in case of No. 1), 2) state.
