How often should the air recirculation mode be switched?

Switch between air recirculation and fresh air modes every half hour. Below is relevant information about vehicle air circulation: 1. Usage methods: Use recirculation mode in traffic jams and fresh air mode on highways. The application of these modes should be coordinated with air conditioning and heating systems. The fresh air mode allows you to breathe outside air. During prolonged highway driving when the cabin air feels stale and uncomfortable with windows closed, activate fresh air mode to introduce ventilation. If winter heating feels too intense, turn off the blower and engage fresh air mode to maintain cabin temperature while getting fresh air for improved comfort. 2. Working principle: Recirculation mode closes the airflow passage between cabin and exterior. Without the blower, no air circulates. When the blower operates in this mode, it only draws air from inside the cabin, creating internal air circulation.

What grade of engine oil is suitable for the 1.5T Ford Kuga?

According to Ford's official recommendation, the Kuga 1.5T requires 5W-20 engine oil. The original factory oil is a light green oil produced by Castrol. You can refer to the vehicle's user manual, which provides detailed instructions. Follow the manual's guidelines when adding engine oil. Precautions for using engine oil are as follows: 1. First and foremost, ensure the oil is genuine. 2. Using counterfeit or substandard oil not only fails to protect the engine but can also damage it. 3. Since the Kuga 1.5T is equipped with a turbocharged engine, and the turbo operates under high temperature and high-speed conditions, failing to use fully synthetic oil will prevent effective engine protection, potentially causing damage and reducing the engine's lifespan.

What are the correct steps for hill starting?

The correct steps for hill starting: 1. On the slope, pull up the handbrake, press the clutch with your left foot, and shift the car into first gear; 2. Slowly and gently lift your left foot to release the clutch while pressing the accelerator with your right foot, feeling the car's forward momentum; 3. Press the handbrake button and push it downward to release the handbrake; 4. The car climbs upward, completing the hill start. The correct starting procedure is: when the car body shakes after releasing the clutch with your left foot, slowly release the brake with your right foot. Avoid releasing the brake too quickly, and keep the clutch steady. If the car shows signs of rolling backward after completing these steps, quickly press the brake and clutch to stop the car, then start again. Stalling usually occurs when the clutch is not held steadily at the semi-engaged point, requiring repeated practice to improve clutch control.

What are the effects of not changing brake fluid?

Not changing the brake fluid will reduce braking force, causing air resistance in the brake lines, thereby affecting braking performance. It may also corrode the brake lines, leading to damage to the internal valves of the anti-lock braking hydraulic assembly, severely impacting the transmission response of the brake system. Prolonged use of brake fluid can also cause wear to the rubber cups and pistons in the brake pump, resulting in contaminated brake fluid. Brake fluid is a solution that easily mixes with water. Over time, some moisture or impurities may enter through the holes in the fluid reservoir, and mixing with water can significantly lower the boiling point of the brake fluid. Once it reaches a certain level, when the driver uses the braking system, many air resistances due to high-temperature evaporation may appear in the pipelines. At this point, the braking force will noticeably decrease or even fail, increasing the risk of driving.
