What Materials Are Needed for Vehicle Maintenance?

Is Crystal Coating Necessary?

Automobile crystal coating is necessary. The benefits of automobile crystal coating are as follows: 1. High brightness: The transparent and clear crystal layer provides an ultimate mirror effect, being 2-3 times thicker than ordinary coatings, without diminishing the brilliant luster. 2. Oxidation resistance: The silicone in the crystal coating material is rich in blemish removal cream, and titanium dioxide is the main component of sunscreen, both of which are extremely stable in nature, forming a protective layer on the car paint surface for up to three years. 3. Memory molecules: The highly resilient elastic crystal layer tightly adheres to the paint surface, perfectly solving the cracking and peeling caused by thermal expansion and contraction. The unique memory molecular structure has a certain repair effect on minor scratches on the crystal-coated surface. 4. High hardness: The perfect inorganic crystal coating layer not only has high toughness but also a hardness of up to 7H, providing excellent protection against sand and dust impacts during driving. 5. Water repellency: It causes rainwater to quickly flow away in sheets, without staying on the paint surface or leaving water stains, avoiding acid rain corrosion and preventing paint damage at the source.

What's the reason for the reversing camera screen going black with only auxiliary lines displayed?

Reversing camera screen going black with only auxiliary lines displayed may be due to aging of the video power cable. Precautions when reversing are as follows: 1. Front of the car: When reversing, the area swept by the front of the car is much larger than the area occupied by the body. Therefore, while paying attention to the rear, do not neglect observing the left and right ends of the front of the car, especially pedestrians passing in front of the car at this time. 2. Areas close to the sides of the car: Areas very close to both sides of the car are not visible, and when turning the steering wheel, the trajectory of the front wheels is an arc, with a difference from the rear wheels. Therefore, scraping may occur when reversing. 3. Area below the rear windshield: Without auxiliary equipment, this area is completely invisible when reversing; on the contrary, even with a reversing radar, it cannot guarantee completely accurate judgment when encountering some low obstacles. 4. The rear right side of the car body: This is the area farthest from the driver and the most difficult to observe, as it is often blocked by the C-pillar. Being at the rear of the vehicle, any slight carelessness can lead to a collision.

What does Subject 3 of the driving test include?

Subject 3 consists of the road driving skills test and the safe and civilized driving knowledge test, which are part of the motor vehicle driver's license assessment. The road driving skills test includes 16 items: vehicle preparation, starting, straight-line driving, gear shifting operations, left turns at intersections, right turns at intersections, lane changes, passing through intersections, pulling over, crossing pedestrian crosswalks, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and nighttime driving. The safe and civilized driving knowledge test covers: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge.

What Causes the Sound of Grinding Brake Discs When the Car Moves?

When the car starts, the sound of grinding brake discs is due to the excessively hard friction material in the brake pads. Here is a related introduction about brake pads: 1. Concept: A brake disc, simply put, is a round disc that rotates as the car moves. The brake caliper clamps the brake disc to generate braking force. When the brake is pressed, it clamps the brake disc to slow down or stop the car. Brake discs provide effective braking and are easier to maintain than drum brakes. 2. Function: Brake discs certainly serve a braking function, with their braking force coming from the brake caliper. Typically, the brake caliper has a fixed inner part where the piston pump is located, while the outer part is a clamp-like structure. The inner brake pad is fixed on the piston pump, and the outer brake pad is fixed on the outer part of the caliper. The piston is pushed by the pressure from the brake fluid line, moving the inner brake pad. At the same time, through reaction force, it pulls the caliper, causing the outer brake pad to move inward. Both pads then press against the brake disc, generating braking force through friction between the disc and the inner and outer brake pads. In this process, the piston is pushed by brake fluid, which is hydraulic oil used to assist the engine. For the handbrake, a cable is used through a lever mechanism to forcibly pull the brake pads, pressing them against the brake disc to generate braking force.

What is the Three Guarantees for Tires?

Tire three guarantees refer to the warranty, replacement, and refund policies. The specific criteria for implementing these guarantees on tires with quality issues may vary among different tire manufacturers, and the final regulations are based on the manufacturer's standards in conjunction with national regulations. The precondition for the three guarantees is that the tire tread must be more than half intact, and the tire must be a genuine product within three years from the production date. Tires are a crucial component of a vehicle, being the only part that comes into direct contact with the ground, and they play a significant role in the vehicle's driving stability and safety. As rubber products, tires are prone to aging over time, hence requiring regular replacement.

What are the length, width, and height of the Southeast DX5?

The length, width, and height of the Southeast DX5 are 4406mm, 1840mm, and 1680mm respectively, with a wheelbase of 2615mm. This vehicle is a compact SUV, equipped with two engines: a 1.5L naturally aspirated engine and a 1.5L turbocharged engine. The 1.5L naturally aspirated engine is paired with a 5-speed manual transmission, while the 1.5L turbocharged engine is matched with either a 6-speed manual transmission or a CVT transmission. The front suspension of the Southeast DX5 is a MacPherson independent suspension, and the rear suspension is a multi-link independent suspension.
