electrical appliances. If the vehicle is left for a long time, the 12-volt battery may dis-
charge, and the hybrid system may be un able to start. (The 12-volt battery
recharges automatically while the hybrid system is operating.)

not unintentionally in contact with an y other than the intended terminal.●
Do not allow the other end of the jumper cable connected to the “+” terminal to
come into contact with any other parts or metal surfaces in the area, such as
brackets or unpainted metal.●
Do not allow the + and - clamps of the jumper cables to come into contact with
each other.●
Do not smoke, use matches, cigarette lighters or allow open flame near the 12-
volt battery.■
