[GabriellaFitz]

The causes of engine shaking in a new car are: 1. Improper air-fuel mixture ratio in the engine compartment; 2. Poor fuel quality; 3. Faulty electronic control system. Precautions for driving a new car include: 1. Maintain smooth starts, avoid sudden acceleration, and do not let the engine RPM run too high; 2. Before starting, ensure the coolant temperature reaches at least 50°C, start in a low gear, and shift to a higher gear after 1 kilometer; 3. Shift gears promptly while driving, avoid prolonged use of a single gear, and refrain from using high gears at low speeds or low gears at high speeds; 4. Choose good road surfaces to avoid excessive vibration and impact, and disengage the clutch before braking; 5. Use high-quality fuel and engine oil, and avoid using engine wear-resistant additives.
