Put the vehicle with the dead battery in neutral, shut it off, and take the key out of the ignition. Expose the battery. Park the vehicle with the working battery several feet away, put it in neutral, and turn it off. Expose the working battery.
Connect one end of the red jump lead to the positive terminal of the working battery, and connect the other end to the positive terminal of the dead battery. Connect the black jump lead to the negative terminal of the working battery, and then clip the other end to a metal object not connected to the dead battery.
Start the working vehicle, wait 60 seconds, and then start the vehicle with the dead battery. If it does not start, wait another minute, and try again. Leave both vehicles running for several minutes.
Disconnect the jump leads, and close the vehicle hoods. Drive the jumped vehicle for at least 30 minutes.
