It warns that the engine compartment is hazardous and recommends only working on the vehicle outdoors or in a well-ventilated area. It instructs users to turn off the engine and let it cool before working, and to exercise caution around moving parts. The manual also advises supporting the vehicle with safety stands when working under it, as the provided jack is inadequate.
