What are the steps to turn on the headlights of a Focus?

The steps to turn on the headlights of a Focus involve twisting the knob located below the left air vent on the steering wheel to switch the headlights on or off. Car headlights, also known as car front headlights or car LED daytime running lights, serve as the 'eyes' of the car, reflecting the owner's external image and being crucial for safe driving at night or in adverse weather conditions. The dimensions of the Focus are: length 4647mm, width 1810mm, height 1468mm, with a wheelbase of 2705mm. It is equipped with a 1.5L naturally aspirated engine, delivering a maximum horsepower of 122PS, a maximum power of 90kW, and a maximum torque of 153Nm, paired with a 6-speed manual transmission.

Where to Find the Car Model Number?

The car model number can be found on the vehicle's identification plate, which is located at the lower part of the front passenger door. This plate contains a unique identifier composed of pinyin letters and Arabic numerals, indicating the car's brand, type, and key specifications. The vehicle identification plate is a label that displays the fundamental characteristics of the car, including the brand, model, engine power, total weight, load capacity or passenger capacity, manufacturing serial number, production date, and manufacturer name. Rules for the vehicle identification number (VIN): 1. Positions 1-3: World Manufacturer Identifier (WMI), indicating the manufacturer of the vehicle; 2. Positions 4-8: Vehicle Descriptor Section (VDS), detailing the vehicle type, body style, etc.; 3. Position 9: Check digit, used to prevent input errors through a specific algorithm; 4. Position 10: Model year, as designated by the manufacturer, with a maximum difference of one year from the actual production year; 5. Position 11: Assembly plant.

How Often Should Engine Carbon Cleaning Be Performed?

During vehicle usage, engine carbon deposits should be cleaned every 20,000 kilometers. Areas requiring carbon cleaning: This includes the engine throttle body, spark plugs, intake manifold, and fuel injectors. Cleaning carbon deposits helps restore vehicle power and reduce fuel consumption. Effects of engine carbon deposits: When carbon deposits adhere to spark plugs, they can affect spark quality or even prevent sparking. When carbon deposits accumulate on oxygen sensors, they prevent accurate exhaust gas detection, leading to incorrect air-fuel ratio adjustments and excessive engine emissions. Carbon buildup in the intake manifold can roughen the surface, affecting the formation and concentration of the combustible mixture. When carbon deposits form between piston rings, they can cause ring sticking, resulting in oil burning and cylinder wall scoring.

What are the regulations for window tinting under the 2021 new traffic rules?

2021 new traffic regulations for window tinting stipulate that the visible light transmittance of the front windshield area in the driver's line of sight and the areas used for observing exterior rearview mirrors while driving must be greater than or equal to 70%. Window glass visible light transmittance exceeding 50%: For highway buses, tourist buses, buses with passenger standing areas, school buses, and passenger vehicles with mid-mounted engines and a width-to-height ratio ≤0.9, the visible light transmittance of all window glass must be ≥50%. No reflective materials allowed: Except for safety signs and information symbols on buses that comply with GB30678 standards, no opaque or mirror-reflective materials (including colored or heat-resistant films) should be applied.

What does the ECON switch in a car mean?

ECON stands for the car's fuel-saving mode switch, which can be used to turn the fuel-saving mode on or off. Modern cars generally offer three driving modes to choose from: fuel-saving mode, comfort mode, and sport mode. Below is information about these three modes: Fuel-saving mode: When the car is in this mode, fuel consumption is relatively low, the throttle pedal sensitivity decreases, and the transmission shifts up more aggressively. Comfort mode: This mode can be considered a normal operating mode for the car. In this mode, the throttle pedal response is more sensitive than in fuel-saving mode. Sport mode: This mode can be used during aggressive driving. When sport mode is activated, the throttle pedal response becomes highly sensitive, and the transmission delays shifting. The transmission will only upshift when the engine speed reaches the redline. After switching to sport mode, the engine speed will remain around 3000 RPM, ensuring better power response during acceleration. Activating ECON mode in a car can reduce fuel consumption and save energy, but it may weaken the car's power. ECON can be understood as an abbreviation for 'economy.' It is generally recommended to keep ECON mode enabled in most situations, except when high torque output is required (e.g., climbing a hill) or when driving at very high speeds, in which case ECON mode should be turned off. Pressing the ECON button puts the car into a low-carbon, eco-friendly driving mode. Subsequently, the ECU, engine, and transmission intelligently execute the driver's intentions in the most fuel-efficient manner, achieving optimal fuel economy through rapid upshifts and smooth acceleration. When the driver presses the throttle pedal deeply, the ECON system effectively controls the opening and closing of the intake valves to ensure smooth engine operation and energy savings. Although ECON mode is simple and effective to operate, it may not function under certain conditions: When the vehicle speed exceeds 120 km/h, priority is given to speed, and the fuel-saving mode automatically deactivates. This means that if the speed exceeds the economical range (typically between 60-90 km/h), the ECON mode will not save fuel. The key to ECON mode is its reliance on computer-controlled operation while driving to be effective. Therefore, it does not function when the car is idling, parked, or in neutral (N), park (P), or manual mode. When the car needs to overcome significant resistance and output higher torque, such as when climbing a hill, the ECU prioritizes ensuring sufficient power to drive the car, and ECON mode will not work in such cases.

What Does a Lens Look Like?

An automotive lens is a circular, completely transparent glass body. The light-gathering function of the lens: Because the lens has strong light-gathering capabilities, it is used for road illumination, making the road surface not only bright but also clear. Since the light dispersion is minimal, the light range is farther and clearer than that of ordinary halogen lamps, allowing drivers to see distant objects in time to avoid missing intersections or targets. The energy-saving function of the lens: The HID bulb inside the lens has a lifespan 8 to 10 times longer than that of ordinary bulbs, eliminating the hassle of frequent replacements. The lens xenon lamp does not require any additional power supply system because a genuine HID gas discharge lamp only needs a voltage stabilizer to convert 12V voltage into normal voltage, providing stable and continuous power to the xenon bulb, thus achieving energy-saving functionality.
