You need to charge your battery/boost your car. Turn off the car lights and then do one of the following:1) Call a service truck to give you a boost.2) Find a friend with some booster cables and give it a boost.3) Hook the battery up to a charger and let it charge for a while, and then start it up.Directions for #2 should be in the car's instruction manual.
