- Only with the braking system.
Show answer and explanation
Correct answer: With both the braking system and the engine.
You use the brakes to slow down, but you can also use the engine. If you take your foot off the accelerator with a gear engaged, the engine slows the car, and the lower the gear, the more it slows it. This engine braking is very useful on long descents, because it keeps you from overheating the brakes.
