Is it good to drive a brand-new car on the highway immediately?

It is not advisable to drive a brand-new car on the highway immediately because new cars have a break-in period, which is crucial for the vehicle. The break-in period of a new car is like an athlete's warm-up before a competition. The quality of the break-in directly affects the car's lifespan, safety, and fuel efficiency. To properly break in your new car, follow these five dos and don'ts: 1. Five Dos: a. Use the correct oil, b. Perform the initial maintenance, c. Start in first gear, d. Shift gears promptly, e. Control your speed. 2. Five Don'ts: a. Do not drive at high speeds, b. Do not operate at full load, c. Do not take long trips, d. Do not engage in emergency braking, e. Do not use it as a training vehicle. Additional information: The break-in period for a new car is generally between 2,500 to 3,000 kilometers. During this period, keep the engine speed around 2,500 RPM to ensure proper contact, friction, and adaptation of all components.

Can dishwashing detergent be used to wash a car, and will it damage the car paint?

Dishwashing detergent should not be used to wash a car as it may damage the car paint. Below is a relevant introduction about the functions of car paint: 1. Protective function: As an outdoor means of transportation, cars are constantly exposed to various corrosive agents in the atmosphere, such as moisture, oxygen, industrial atmosphere, sulfur dioxide, carbon dioxide, and nitrogen dioxide. Car paint forms a firmly adhered continuous film on the car, preventing chemical or electrochemical reactions between the surface and surrounding media, thereby stopping or delaying the occurrence and development of damage to the car. 2. Decorative function: Applying various bright-colored paints to the car's surface makes it appear beautiful, elegant, lively, and pleasant, giving people a sense of beauty and showcasing the vehicle's personality. A full and glossy paint film can also enhance the car's grade. 3. Identification function: The color of car paint can serve as a marker for the type and purpose of the vehicle, such as green for postal vehicles and white for ambulances. Some car paints can improve the comfort and sealing of the car, preventing noise caused by vibrations.

How to Turn on the Fog Lights of Ford Focus?

Focus fog lights are located on the knob at the lower left position of the steering wheel. To turn them on, rotate the knob to the second level (right rotation) in the low beam position, then pull the knob outward to activate the fog lights. Additional information: 1. The purpose of fog lights is to make your vehicle visible to others in foggy or rainy conditions where visibility is significantly affected by weather. Therefore, fog light sources need strong penetration capability. Most vehicles use halogen fog lights, while LED fog lights are a more advanced option. 2. Fog lights must be installed below the bumper, at the position closest to the ground, to ensure their effectiveness. If mounted too high, the light cannot penetrate rain or fog to illuminate the road surface (fog is generally thinner below 1 meter), which may cause hazards. 3. Fog light switches typically have three positions: position 0 is off, position 1 controls the front fog lights, and position 2 controls the rear fog lights. When set to position 1, only the front fog lights work; when set to position 2, both front and rear fog lights operate simultaneously. Therefore, when turning on fog lights, it is recommended to know which switch position corresponds to which lights to ensure driving safety.
