Pontiac 2004 Vibe - Manual (Page 135)

Your vehicle also has a safety belt reminder light for the
right front passenger position.
This light is located on the
center of the instrument
panel, above the audio
system.
When the key is turned to ON or START, this light will
come on as a reminder for the right front passenger
to fasten the safety belt. The safety belt light will flash
until the right front passenger’s safety belt is buckled.
The passenger’s safety belt reminder light will not
illuminate if the right front passenger’s belt is already
buckled or if a sensor does not detect the weight
of a passenger in that seat.
If something is placed on the right front passenger’s
seat, the sensors in the seat may detect that object and
cause the right front passenger’s safety belt reminder
light to come on. If this ever happens, move the object to
the rear seat or place it in a rear storage area, if at all
possible.
