GMC Terrain: Warning Lights, Gauges, and Indicators / Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a driver seat belt reminder light on the instrument cluster.
When the vehicle is started, this light flashes and a chime may come on to remind the driver to fasten their seat belt. Then the light stays on solid until the belt is buckled. This cycle may continue several times if the driver remains or becomes unbuckled while the vehicle is moving.
If the driver seat belt is buckled, neither the light nor the chime comes on.
Passenger Seat Belt Reminder Light
There is a passenger seat belt reminder light near the passenger airbag status indicator. See Passenger Sensing System.
When the vehicle is started, this light flashes and a chime may come on to remind passengers to fasten their seat belt. Then the light stays on solid until the belt is buckled. This cycle continues several times if the passenger remains or becomes unbuckled while the vehicle is moving.
If the passenger seat belt is buckled, neither the chime nor the light comes on.
The front passenger seat belt reminder light and chime may turn on if an object is put on the seat such as a briefcase, handbag, grocery bag, laptop, or other electronic device. To turn off the reminder light and/or chime, remove the object from the seat or buckle the seat belt.
