How to Jump Start a Buick Verano

1. Make sure the other vehicle has a 12-volt battery with a negative ground system, and park the two vehicles so they do not touch.
2. Set the parking brake firmly and put the shift lever in P (Park), then turn the ignition to LOCK/OFF and switch off lights and accessories in both vehicles.
3. Connect one end of the red positive (+) cable to the positive (+) post (2) on the discharged battery.
4. Connect the other end of the red positive (+) cable to the positive (+) post (4) of the good battery.
5. Connect one end of the black negative (–) cable to the negative (–) post (3) of the good battery.
6. Connect the other end of the black negative (–) cable to the negative (–) grounding point (1) on the discharged vehicle.
7. Start the engine of the good vehicle and let it idle for at least four minutes, then try starting the dead vehicle.
8. Remove the cables by reversing the connection sequence exactly, then let the started vehicle idle for several minutes.

• The jump start positive post is in the engine compartment on the driver side, under a trim cover; the negative point is the engine block or an engine mounting bolt.
• If the vehicle will not start after a few tries, it probably needs service.
• Connecting or removing cables in the wrong order can cause electrical shorting and damage.
