Jump Starting If you cannot start your vehicle and you are unable to remove your key from the ignition, see "Shift Lock Release" in the Index. If your battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Please follow the steps below to do it safely. CAUTION: Batteries can hurt you. They can be dangerous because: D They contain acid that can burn you. D They contain gas that can explode or ignite. D They contain enough electricity to burn you. If you don't follow these steps exactly, some or all of these things can hurt you. NOTICE: If the other system isn't a 12-volt system with a negative ground, both vehicles can be damaged. 5-3
