1995 Pontiac Bonneville Owner's Manual - Page 182

To Jump Start Your Pontiac 1. Check the other vehicle. It must have a 12-volt battery with a negativeground system. 3. Turn off the ignition on both vehicles. Turn off all lamps that aren't needed, and radios. This will avoid sparks and help save both batteries. And it could save your radio! NOTICE: If the other system isn't a 12-volt system with a negative ground, both vehicles can be damaged. 2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren't touching each other. If they are, it could cause a ground connection you don't want. You wouldn't be able to start your Pontiac, andthe bad grounding could damage the electrical systems. You could be injured if the vehicles roll. Set the parking brake firmly on each vehicle. Put an automatic transaxle in PARK (P) or a manua1 transaxle in NEUTRAL (N). NOTICE: If you leave your radio on, it could badly be damaged. The repairs wouldn't be covered by your warranty. 4. Open the hoods and locate the batteries. 5-3
