- interior lamp
- panic alarm
- hazard reminder

OPERATED PROCEDURE
Power Door Lock Operation
When the following input signals are both supplied:
- key switch OFF (when ignition key is not inserted in key cylinder)
- door switch CLOSED (when all the doors are closed)
The two above signals are already input into smart entrance control unit. At this point, smart entrance control unit receives a LOCK signal from remote controller. Smart entrance control unit locks all doors with input of LOCK signal from remote controller.
When an UNLOCK signal is sent from remote controller once, driver's door will be unlocked.
Then, if an UNLOCK signal is sent from remote controller again within 5 seconds, all other door will be unlocked.

Hazard Reminder
Power is supplied at all times
- to multi-remote control relay terminal 1
- through 15 A fuse [No. 20, located in the fuse block (J/B)].
When smart entrance control unit receives a LOCK signal from remote controller, ground is supplied
- to multi-remote control relay terminal 2
- through smart entrance control unit terminal 7.
Multi-remote control relays are now energized, and hazard warning lamp flash twice as a reminder. For detailed description, refer to "TURN SIGNAL AND HAZARD WARNING LAMPS"

Interior Lamp Operation
