Seat Belt Reminder Lamp: Description and Operation
SYSTEM OUTLINE
1. SEAT BELT WARNING SYSTEM
When the ignition SW is ON and the driver's seat belt is not used, the warning light on the combination meter blinks and the buzzer sounds at the
same time to warn the driver. As for the front passenger's seat, only when the built-in occupant detection sensor in the buckle SW RH detects that
the front passenger is seated, the system warns the passenger by the warning light (w/o LEXUS navigation system) or the multi-display (w/
LEXUS navigation system).
2. KEY REMINDER SYSTEM
If the front door on the driver's side is opened with the ignition key inserted in the cylinder and the ignition SW is OFF or ACC, the buzzer sounds
to prevent the driver from forgetting to pull out the ignition key.
