What are the precautions for new drivers taking a new car on the highway?

Can a car with modified body kit pass the annual inspection?

If the modified body kit has been registered with the vehicle management office, it can pass the annual inspection. If not registered, it cannot pass the inspection. Changes to the vehicle's body color, model, performance, purpose, and structure, as well as replacement of the frame, body, or engine, all require applying for modification registration with the vehicle management office. Body kits are divided into small and large kits, and modifying them is considered an alteration to the car's appearance, thus requiring registration with the vehicle management office. Otherwise, it is easy to be penalized by traffic police or fail the annual inspection. Vehicles with any of the following conditions must undergo the necessary procedures before they can be inspected: discrepancies between the vehicle's condition and the records in the driving license or archives; damaged, incomplete, or illegible license plates or driving licenses, or self-made license plates; vehicles with modifications, model changes, or technical transformations that have not undergone approval and modification procedures; failure to display the unit name and enlarged license plate number as required; failure to install alarms or indicator lights as required; failure to pay road maintenance fees and insurance as required.

What to Do About Abnormal Noises During Cold Start?

Abnormal noises during cold start may be caused by faulty hydraulic lifters or improper use of engine oil. Below are the specific reasons for abnormal noises during cold start: 1. This could be due to improper use of engine oil, low oil pressure, or wear in the hydraulic lifters themselves, allowing air to enter the hydraulic lifters, resulting in a ticking sound. 2. Wear in the valve rocker arms causing excessive valve clearance, preventing the formation of an oil film in time during cold start. 3. The sound of the carbon canister solenoid valve operating, which is normal. 4. A clicking sound within the first half minute that disappears afterward is usually caused by the expansion of the catalytic converter as it heats up, which is normal. 5. A loud clicking sound during cold start is mostly related to the engine's timing system, such as wear, elongation, or loosening of the timing belt/chain.

Where is the windshield washer fluid?

Location of the windshield washer fluid: Inside the blue cap on the left side under the hood. Below are the functions of the windshield washer fluid: 1. Cleaning performance: Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving cleaning and stain removal. 2. Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze effects and quickly dissolving frost. 3. Anti-fog performance: A single-molecule protective layer forms on the glass surface, preventing the formation of fog droplets and ensuring clear visibility through the windshield. 4. Anti-static performance: After cleaning with windshield washer fluid, substances adsorbed on the glass surface eliminate static charges, providing anti-static properties. 5. Lubrication performance: The ethylene glycol in the fluid has high viscosity, offering lubrication to reduce friction between the wiper and the glass, preventing scratches. 6. Anti-corrosion performance: The fluid contains various corrosion inhibitors, ensuring no corrosion on any metal and absolute safety for car paint and rubber.

Can D Gear Be Switched to S Gear?

D gear can be switched to S gear, and there is no need to press the brake pedal during the switch because both D gear and S gear are forward gears. However, after switching to S gear, the car's power will be stronger, and the throttle pedal's sensitivity will also increase. S gear is the car's sport mode (S stands for sport). How to use S gear: 1. To switch to manual mode, you must shift the gear to D gear and then push the gear lever to the right. At this point, the transmission first enters sport mode; 2. Then, you can shift gears by pushing the gear lever forward or backward. In Volkswagen cars, pushing forward is for upshifting, and pushing backward is for downshifting. You can see the current gear from the upper right corner of the central screen on the dashboard; 3. If you want to switch back to automatic mode, simply push the gear lever to the left to the D gear position to complete the switch. At this point, the gear will be controlled by the computer.

Is Higher or Lower Engine Oil Viscosity Better?

Introduction to engine oil viscosity is as follows: 1. Low viscosity: The lower the engine oil viscosity, the thinner the oil film, the better the fluidity, and the relatively smaller resistance to engine operation; however, its ability to resist shear under high temperature and pressure is weaker. The smaller the number before W, the lower the viscosity at low temperatures, the better the low-temperature fluidity, and the lower the applicable minimum temperature. It is easier to start at low temperatures, and the oil can quickly reach the friction surface after starting, helping to reduce engine wear at low temperatures. 2. High viscosity: The higher the engine oil viscosity, the thicker the oil film, the weaker the fluidity, and the relatively greater resistance to engine operation, but its ability to resist shear under high temperature and pressure is better, helping the friction pair resist wear under greater pressure. The larger the number before W, the higher the viscosity at low temperatures, the worse the low-temperature fluidity, and if used at temperatures beyond its capability, it may result in failure to start. Users should choose engine oil viscosity based on their vehicle's requirements.

What to Do When a Truck Consumes Excessive Urea?

The situation where a truck consumes excessive urea is as follows: 1. Vehicle urea plays a critical role in vehicle power, fuel consumption, etc. If diesel engine exhaust fluid is loaded or urea solutions of insufficient purity and poor quality are used, it can cause the vehicle's engine to automatically decelerate. At the same time, poor-quality diesel engine exhaust fluid can pollute the catalyst in the SCR catalytic reaction tank, leading to damage to the components of the after-treatment system. 2. Urea is added for diesel engine vehicles because diesel engines emit harmful nitrogen oxide gases, causing environmental pollution. Inhaling these exhaust gases can harm human health. To reduce this hazard, urea is added to diesel engine vehicles. It has a catalytic function, reacting chemically with nitrogen oxides to convert them into nitrogen and water, which are then expelled. Moreover, urea is consumed whenever the vehicle is in motion, so it needs to be replenished regularly. 3. Qualified urea solution is synthesized from NOX with 32.5% ultra-pure urea and pure water. Vehicle urea solution, through selective catalytic reduction with NOX products, converts them into nitrogen, oxygen, and water, thereby reducing nitrogen oxide emissions. It is suitable for all Euro IV and Euro V emission diesel engine SCR systems.
