How should I connect the battery when installing the Trailblazer 325?

Always stop the engine before connecting or disconnecting battery cables. Observe correct polarity (+ and −), and always disconnect the negative (−) cable first and connect it last to avoid sparks or accidental starting. (Pages 7, 23)
