190 Starting and driving WARNING Charging the battery/Jump starting To avoid damaging the car's electrical system and electronics, the following rules must be followed when charging the battery or jump starting the car. • If the charger 1 or starter unit 1 can be set to different voltages (6V/12V/18V/24V), 12V must be selected. • Follow the manufacturer's instructions supplied with the charger or starter unit. • Nothing that is plugged into an electrical outlet should be connected to the car during charging or jump starting. • The charger or starter unit must under no conditions produce a voltage greater than: • 16V continuous • 18V for 60 min. • If you are unsure about the charge rating of the unit, disconnect the battery clamp from the positive terminal before connecting the unit to the battery. Do not let the other end touch anything until the next step. The other end of the negative cable does not go to the dead battery. It goes to a major metal part with a good ground on the engine of the vehicle with the discharged battery. 9 Attach the cable at least 18 inches (45 cm) away from the discharged battery, but not near engine parts that move. To avoid an arc which could detonate the hydrogen gas around the battery, the final connection must be at least 18" from the battery. 10 Start the vehicle with the good battery and run the engine for a while. 11 Try to start the vehicle with the discharged battery. If it does not start after a few tries, it probably needs service. 12 Remove the cables in reverse order to prevent electrical shorting. Take care that they do not touch each other or any other metal.
