Vehicle Care 10-79 Jump Starting Jump starting is connecting jumper cables between the two vehicles to enable vehicle starting. If the Volt or another vehicle has a run‐down 12‐volt battery, it can be jump started using good condition jumper cables. There are different procedures depending on if the Volt has a run‐down battery or another vehicle has a run‐down battery. Read the appropriate procedures that follow. { WARNING Batteries are dangerous and can cause injury. Batteries contain acid and can explode or ignite. They contain electricity that can burn. Follow the exact steps provided or injuries could occur. Using an open flame near a battery can cause battery gas to explode; you or others could be hurt. Battery acid can cause blindness. Be sure the battery in the other vehicle has enough water. Add water if the level is low. A low water level could cause explosive gas to be present. Battery fluid contains acid that can burn. If battery fluid gets in eyes or on skin; flush with water and get medical help immediately. { WARNING Electric fans can start up even when the engine is not running and can cause injury. Keep hands, clothing, and tools away from any underhood electric fans. Notice: Ignoring these steps could result in costly damage to the vehicle that would not be covered by the warranty. Trying to start the vehicle by pushing or pulling it will not work, and it could damage the vehicle. { WARNING The high voltage battery cannot be jump started either with another vehicle or battery charger. Personal injury, death, or damage to the vehicle could result.
