How do yoiu jump start a 1995 Buick Riviera?

Their is a "jump start" connector under the hood. Near pass shock tower, near belts. You have to open the plastic cover labeled "jumpstart". Hook negative up to bolt on motor mount.

Start "live" vehicle

Connect + cable from "live" vehicle to + battery terminal on "dead" vehicle

Connect - cable from "live" vehicle to good engine ground on "dead" vehile

Let vehicles sit for about 5 minutes allowing "live" to charge "dead"

Try to start "dead" vehicle

If yours is like my 98, and the battery is under the backseat, there is a little black box on the top of the wheel well inside the engine compartment on the left side. It has a + sign on it. Flip up the plastic lid. This is the positive terminal. Hook up the negative to the engine or frame for a ground. This is how you jump it, or put a boost pack on it to start the car. I have been told, never to boost another car with this method. It will damage the battery and/or car. Only boost another car with a Riviera by hooking up directly to the battery. You will need long cables. LOL
