What items should a new car be equipped with?

After purchasing a new car, you can add items such as a dash cam, parking sensors, fire extinguisher, odor-absorbing charcoal bags, and child safety seats, which are all quite necessary and useful. You can also install seat covers, paint sealant, or mud flaps according to your needs. If it's a training vehicle, please attach a "Student Driver" label. The following are precautions for driving a new car: 1. Avoid using the same speed and gear for extended periods; instead, use different gears appropriately to allow each gear to undergo proper break-in. 2. Avoid sudden braking, as it can strain the engine and affect the braking system's performance. Also, refrain from long-distance driving. 3. If time permits, warm up the engine before starting to ensure full lubrication. Wait until the engine idle sound stabilizes and the coolant temperature reaches normal levels before driving. 4. It's best not to overload the car initially; keep the load below 80% of the maximum capacity to reduce the engine's burden.

Is it still necessary to display the vehicle environmental protection label?

The vehicle environmental protection label is not mandatory. The reasons are as follows: 1. According to relevant laws and regulations, traffic police currently only penalize vehicles that fail to correctly display the annual inspection label and insurance label, both of which must be affixed to the upper right corner of the vehicle as required. There are no laws or regulations stipulating that the environmental protection label must be displayed, and traffic police will not penalize vehicles without it. 2. The vehicle environmental protection label is a classification label issued by the state for vehicle emission standards, divided into yellow and green categories. It is issued after reviewing the vehicle type and emission standards, aiming to facilitate energy-saving and emission-reduction inspections and periodic environmental checks for vehicles. Functions of the environmental protection label: 1. Serves as proof of compliance with vehicle emission standards. 2. Acts as a basis for determining the periodic environmental inspection cycle for vehicles. 3. Under high-emission vehicle traffic control measures, it serves as a pass for vehicles to travel in restricted areas.

What are the reasons for insufficient starting power of the Baojun 510?

The reasons for insufficient starting power of the Baojun 510 are as follows: 1. It may be caused by problems with the engine or transmission, which is a fault-related issue leading to weak starting power and requires timely troubleshooting; 2. It could also be due to the vehicle's small displacement and heavy load, where the starting speed may not reach the boost level, resulting in a feeling of weak starting power, which is a normal phenomenon. The specific reasons for insufficient starting power are as follows: 1. Engine: Carbon buildup is a major culprit causing insufficient engine power and weak starting. Carbon buildup on the throttle valve affects the intake volume; buildup on the spark plugs affects ignition; buildup on the fuel injectors affects fuel injection, and overheated carbon buildup can cause detonation, leading to weak starting power. Therefore, it is advisable to clean the engine's carbon buildup first before looking for other possible causes of weak starting power. 2. Transmission: Clutch failure in the transmission can lead to weak starting power. The clutch's role is to transmit and cut off the engine's power. Manual transmissions, dual-clutch transmissions, etc., use friction plate clutches. Over time, the friction plates wear out severely, causing slippage, which in turn leads to weak starting power.

What is the appropriate light transmittance for car window films?

According to the industry standard "CB/31849-2015 Automotive Film Glass", the front windshield requires a light transmittance of 70%, which meets national regulations for base materials. High-quality explosion-proof films should feature eco-friendly materials, high clarity, excellent explosion-proof performance, strong heat insulation, and effective UV blocking. Premium films can achieve up to 90% light transmittance and heat insulation rates, with UV blocking rates no less than 98%. Below is extended information about car window film light transmittance: 1. The front windshield is the main area exposed to sunlight, and proper films can effectively prevent tanning and interior fading. Always choose certified films. 2. Car window film light transmittance refers to the phenomenon where light is blocked by the glass and reflected at certain angles, known as "reflection", measured by reflectance. When light passes through the glass, part of its energy is lost, known as "absorption", measured by absorption rate.

How to Transfer the Old Car ETC to a New Car?

The method to transfer the old car ETC to a new car is as follows: the car owner should bring the vehicle license and ID card, fill out a change form, remove the ETC device, then go to the purchase location for re-matching, visit an ETC service point to process data changes, install the old ETC on the new car, and reactivate it. The ETC activation process is: Insert and remove the ETC card twice in succession until the electronic tag screen displays "Bluetooth is on". If inserting and removing twice without attaching the electronic tag shows "Tag invalid", it is a normal phenomenon and does not affect activation. Alternatively, you can directly press the button on the top of the electronic tag to enable the Bluetooth function. Turn on the phone's Bluetooth, open the corresponding mobile app (usually there is a download QR code on the electronic tag), and enter the device activation interface. Click on device connection and wait patiently for the "Connection successful" prompt. After successful connection, upload a photo of the vehicle's front to complete the activation.

How to Cancel the Low Tire Pressure Warning Light?

Adjust the tire pressure to the standard level, then drive for a while, and the low tire pressure warning light will usually cancel automatically. Hazards of Low Tire Pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and tendencies to drift, which are factors detrimental to driving safety; Increases movement in various parts of the tire, leading to excessive rolling and abnormal heat generation; Reduces the functionality of the cord and rubber, causing delamination or cord breakage, excessive friction with the rim, resulting in damage to the bead area and abnormal wear; Multiplies the friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a blowout; Increases tire body deformation, making the tire side prone to cracking, while generating flexing motion, leading to excessive heat, accelerating rubber aging, fatigue of the cord layer, cord breakage, and also increases the tire's contact area with the ground, accelerating shoulder wear.
