Why does a small car fail the annual inspection due to excessive exhaust emissions?

How to switch back to total mileage from trip km?

Here are the steps to switch back from trip km to total mileage: 1. First, press the vehicle's one-touch start button to start the engine; otherwise, the switch cannot be made. 2. Then, observe the dashboard and notice that it displays the trip mileage. 3. Next, press the cruise control on/off button on the left side of the multifunction steering wheel to turn off cruise control. 4. Finally, press the OK button on the right side of the multifunction steering wheel to switch the trip mileage to total mileage. Here are some related details: 1. The odometer can display both the total accumulated mileage and the single-trip mileage. It becomes operational when the ignition is turned on. The total accumulated mileage display mode can show a maximum distance of 999,999 km, while the single-trip mileage display mode can show up to 9999.9 km. 2. Briefly pressing the reset/adjustment button (set) allows you to toggle between the two mileage display modes. In single-trip mileage display mode, holding the reset/adjustment button (set) for more than two seconds will reset the single-trip mileage display to zero.

How Often Should Standard Spark Plugs Be Replaced?

Standard spark plugs should be replaced every 30,000 kilometers, platinum spark plugs around 60,000 kilometers, and iridium spark plugs around 80,000 kilometers. The replacement cycle varies due to differences in car brands and the types of spark plugs used, so replacement should be based on actual conditions. Below is some relevant information about spark plugs: 1. The gap between the electrodes of a spark plug greatly affects its performance. If the gap is too small, the spark will be weak and prone to carbon buildup and leakage. If the gap is too large, the required breakdown voltage increases, making the engine harder to start and more likely to misfire at high speeds. 2. Spark plugs, commonly known as "fire mouths," mainly include standard spark plugs, insulator projection spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs.

How much longer can brake pads with 5mm thickness be used?

It is best not to continue driving with brake pads that are 5mm thick and to replace them promptly. Regularly check whether the brake pads and discs are thin; you can use a small flashlight for observation. If the black friction material of the brake pads is nearly worn out and the thickness is below 5mm, you should consider replacing them. Below are methods for self-inspecting brake pads: 1. Based on pad thickness: Measure the thickness of the brake pads. A new brake pad is approximately 1.5cm thick, with a wear limit of 0.3cm. When the brake pad thickness approaches or falls below 0.3cm, it must be replaced. 2. Feel the change in braking force: Another very intuitive method is to feel the change in braking force when pressing the brake pedal. If you always feel that it requires more effort to brake, or if the brakes are not as responsive as before, needing more force than usual to achieve the desired braking effect, it may be time to replace the brake pads. 3. Observe the warning light: When the brake pad wear warning light on the dashboard illuminates, it indicates that the brake pads need to be inspected and replaced.

Will Running a Red Light on a Motorcycle Be Captured by Cameras?

Running a red light will be captured by electronic surveillance cameras because motorcycles are classified as motor vehicles. According to Article 2 of the "Scoring Standards for Road Traffic Safety Violations," running a red light results in a 6-point deduction and a fine. Running a red light refers to the act of a motor vehicle violating traffic signal instructions by crossing the stop line and continuing to move when the red light is on, which prohibits passage. Determining a red-light violation requires at least three pieces of photographic evidence: the vehicle has not left the stop line when the red light is on; the vehicle passes through the intersection when the red light is on; the vehicle has crossed the line and continues to move forward when the red light is on. Common scenarios of running a red light: When the red light is on, if the front wheel touches the stop line but the vehicle stops immediately, it is not considered running a red light. However, if the vehicle continues to move, it is counted as running a red light. According to Article 3 of the "Scoring Standards for Road Traffic Safety Violations," if the vehicle completely crosses the stop line and stops on the crosswalk after the red light is on, it is not considered running a red light but is classified as over-the-line parking, which incurs a 2-point deduction. If the vehicle moves noticeably on the crosswalk or obstructs pedestrian passage, it will be judged as running a red light. If the front wheel crosses the stop line and then reverses back behind the stop line when the red light is on, it is considered illegal reversing, which also incurs a fine. If this causes a traffic accident with a rear vehicle, the driver will bear primary responsibility. If the vehicle crosses the stop line and the crosswalk, reaching the opposite intersection after the red light is on, this is considered running a red light. Ways to avoid running a red light: Follow the arrow signal if present; otherwise, follow the circular signal. When the red light is on, the front of the vehicle must not cross the stop line. When the yellow light is on, the front of the vehicle must not cross the stop line. When the green light starts flashing, if the vehicle is close and moving fast, it should proceed, as braking might not stop it in time to avoid crossing the stop line. If the vehicle is far away, moving slowly, or the intersection is congested, it should stop. When driving in the city, develop the habit of looking for traffic lights whenever you see a crosswalk, stop line, or intersection.

How Often Should Rear Brake Pads Be Replaced?

Under normal circumstances, rear brake pads should be replaced every 50,000 to 80,000 kilometers. However, this mileage refers to the theoretical replacement cycle of rear brake pads. The actual replacement interval depends on the frequency of brake usage and the quality of the brake pads. Generally, the wear condition of brake pads should be checked every 30,000 kilometers. Steps for replacing car brake pads: 1. Open the engine compartment and check whether the brake fluid level is at the normal position to avoid overflow during the brake pad replacement process. 2. Use a jack to align with the support points under the car, raise the tire until it completely leaves the ground, and then remove the tire. 3. Use a wrench combined with a socket to remove the bolts of the brake caliper and directly take off the brake pads. 4. Push the brake piston back to its original position and install the new brake pads. 5. After installation, check the brake fluid level. Press the brake pedal firmly several times and then add brake fluid again to ensure the fluid level is at the max mark.

How to Steer Through an S-Curve by Reference Points?

S-Curve steering techniques by reference points are as follows: 1. When the midpoint of the car hood touches the right yellow line, gradually start turning the steering wheel to the left—first half a turn—keeping the left corner of the hood aligned with the yellow line. If the left corner is about to go beyond the yellow line, turn a bit more; if it fails to touch the line, slightly readjust the steering wheel back, continuously making minor corrections. 2. When the car hood is centered at the junction of the curves, quickly straighten the steering wheel, usually by turning it back about one full rotation. 3. When the midpoint of the car hood touches the left yellow line, turn the steering wheel to the right by half a turn initially, then make incremental adjustments, following the curve. Precautions for navigating an S-curve: 1. Use the rearview mirrors appropriately. 2. Adjust your seating position and rearview mirrors. 3. Control the vehicle speed.
