Go to the front of the vehicle and locate the secondary release lever under the front center of the hood. Push the secondary hood release lever to the right to disengage
Yes, in the very center of the hood; I was in the same boat last week, fumbling for the latch when needing to perform the required professional periodic maintenance on the Bolt: Adding windshield wiper fluid.the hood latch is there. just a little different as you really got to fish with your fingers. and it will flex such that it will be bending instead of releasing. without running to the garage, if I recall correctly, it's a side movement. one way being correct. don't force it.
edit: manual has a picture with the side direction being to the right for release.
