What do vehicle systems include?

Vehicle systems encompass various components that work together to ensure the overall functionality and safety of the vehicle. The correct choice identifies essential systems responsible for the vehicle's operation, including the engine, which powers the vehicle, the fuel system that supplies the engine with fuel, the exhaust system which manages emissions and directs exhaust away from the engine, and the steering system that allows the driver to control the vehicle's direction.

These systems are fundamental for a vehicle to operate efficiently and safely on the road. Understanding these components helps drivers appreciate the engineering that goes into vehicle design and the importance of proper maintenance. The other options, while including systems and features relevant to vehicle operation, do not specifically highlight the core mechanical and operational components critical to a vehicle's performance.
