Detailed introduction for running a new car on the highway is as follows: 1. Maintain a reasonable speed: Avoid driving at low speeds or accelerating rapidly with high RPM. It is best to keep the speed within 100km/h, and pay attention to the engine RPM and speedometer during driving. The engine RPM should preferably not exceed 3000. 2. Avoid flooring the accelerator when starting or slamming on the brakes: Emergency braking will impact the braking system and increase the load on the chassis and engine. 3. For manual transmission models, use the gears appropriately and avoid driving in low gear for extended periods: Neither high gear at low speed nor low gear at high speed is the best option. 4. Do not drive with a full load or overload, as this can damage the new car's components: If the new car is used in winter in the north, allow sufficient time for the engine to lubricate before starting, and briefly warm up the vehicle.

I've got experience with taking a new car on the highway - best not to floor the accelerator right away. The engine is still in its break-in period, so maintaining around 100 km/h is advisable. Pushing too hard can easily rev the engine past 3,000 RPM, which isn't ideal for gear break-in. My approach is keeping it between 90-100 km/h for the first 500 km, then gradually increasing to 110 km/h for the next 500 km. Weather conditions matter too - rainy days call for reducing speed to 80 km/h for safety. On highways, don't just focus on speed limits; maintain at least 150 meters following distance. New brake pads also need breaking in - emergency stopping distances are about 20% longer than normal. Keep an eye on the coolant temperature gauge too, as long drives put extra stress on the cooling system. Safety first - no need to rush.

Why don't new cars need to go to the DMV for annual inspection?

Because it can be done online. You can apply online by logging into the DMV website and submitting the relevant materials. Annual inspection regulations: In 2021, the DMV's new regulations state that starting from September 1st, the annual inspection process has been readjusted, and it will no longer be necessary to visit the DMV to collect the inspection certificate. The new regulations indicate that new cars within six years do not require an annual inspection, nor do they need to visit the DMV to collect the inspection certificate. The DMV states that as long as you log into the DMV website, complete the information according to your details, and follow the steps for review to obtain the inspection certificate, the relevant department will mail the required materials or the inspection certificate to the address specified by the vehicle owner. Applicable scope: This only applies to new car owners who need to obtain an inspection certificate from the DMV within six years. However, owners of cars older than six years still need to undergo annual inspections.

Why does the car bounce so much after installing coilover suspension?

It may be due to the damping being set too stiff or too high. Coilover suspension adjustment instructions: The higher the spring seat height, the stiffer the spring performs, and vice versa; When adjusting the spring seat, the vehicle height will also change proportionally (definitely not 1:1); Only when the damping coefficient matches the spring can the highest performance be achieved; Damping is not the bigger the better - excessive damping will cause insufficient spring travel, resulting in severe bouncing of the entire vehicle; Adjusting the shock body height does not affect spring stiffness. Meaning of coilover suspension: Coilover suspension (Height Adjustable Damper) - derived from racing technology, refers to shock absorbers with adjustable (spring) height design; When the vehicle is stationary, the ground clearance at the four corners of the body has a significant impact on the wheel load at that position: Increasing the ground clearance at the left rear corner will increase the load on the left rear wheel and its diagonal wheel (i.e. the right front wheel), while reducing the load on the other diagonal wheels (left front and right rear wheels).

What is the fuel tank capacity of the new M3000?

The fuel tank capacity of the Delong New M3000 is 700L. Types of fuel tanks: Fuel tanks can be divided into open-type and closed-type. Open-type fuel tanks have their liquid surface in contact with the atmosphere, and an air filter is installed on the tank cover. Open-type fuel tanks have a simple structure and are easy to install and maintain, making them commonly used in hydraulic systems. Closed-type fuel tanks are generally used for pressurized tanks, filled with a certain pressure of inert gas, with an inflation pressure of up to 0.05MPa. Fuel tank maintenance: Maintenance of the fuel tank mainly involves, during the first-level vehicle maintenance, draining accumulated water and sediment from the tank, and checking for oil leaks at pipe joints and switches. For fuel tank covers equipped with air valves and steam valves, it is also necessary to check whether the ventilation holes are clear. The filter screen at the fuel filler neck should remain intact to prevent impurities from entering the tank during refueling and clogging the fuel lines. The sealing gasket on the fuel filler cap should also be intact to prevent fuel from spilling out while driving.

Do Charging Voltage and Battery Voltage Require Certification?

Driving an electric vehicle requires a driver's license. Electric vehicles fall under the category of small automatic transmission models, and obtaining a C2 driver's license is sufficient. The C1 driver's license allows driving both small manual and automatic transmission vehicles, while the C2 license is only for small automatic transmission vehicles. When taking the driver's license test, it is important to strictly follow the examination rules, paying attention to details and regulations. Both C1 and C2 require passing the assessments for Subject 1, Subject 2, Subject 3, and Subject 4. Subjects 1 and 4 are written tests, where it is crucial to carefully read and understand the questions (examining the questions) to provide correct answers. The written test portion has no difficult questions; all are multiple-choice questions on laws and regulations. By repeatedly practicing the questions, one can familiarize themselves with the content and correct answers. During the test, it is essential to read the questions carefully and answer attentively. Subjects 2 and 3 involve strict practical operations, requiring adherence to the examination process and planned routes. Pay attention to details: fasten the seatbelt upon entering the vehicle, close the car door, and after the test begins and ends, remember to wait for the system to notify that the test has been passed before unfastening the seatbelt, opening the car door, and exiting the vehicle, among other operations.

What is the black border on the upper part of the car door called?

The border at the lower part of a car door is the bottom of the car, which is part of the body frame and serves to protect passengers in the event of a side collision. Below is a detailed introduction: 1. Basic Introduction: A car's body is divided into cover panels and the frame. Cover panels include doors, front and rear bumpers, the engine hood, front fenders, and the trunk lid. After removing all cover panels, what remains is the body frame. 2. Body Protection: In the event of an accident, it is not the cover panels but the body frame that protects the passengers. The rocker panel (or 'bottom sill') is part of the body frame and, along with the B-pillar, absorbs most of the impact force in a side collision. During regular use, the rocker panel is also prone to scratches. If driving on rough roads, it is very easy for the rocker panel to get scratched by stones. Due to its hardness, dents caused by scratches are difficult to repair. Therefore, drivers should pay attention to protecting the bottom of the car during daily use. 3. Repair Methods: If the rocker panel has been repaired, it must be coated with anti-chip or textured coating; otherwise, it is highly susceptible to rust. The rocker panel is usually coated with a layer of textured coating at the factory, which protects it and prevents rust.
