The ambient light on the co-pilot side of the Hongqi H9 not working is caused by the aging of the ballast, which leads to an increase in internal resistance. Below are specific details about the Hongqi H9: 1. Interior: The new car features a 12.3-inch full LCD instrument panel and a similarly sized 12.3-inch central multimedia touch screen, paired with a three-spoke multifunction steering wheel. Additionally, the new car offers both standard 5-seat models and 4-seat versions for consumers to choose from. 2. Powertrain Configuration: The Hongqi H9 is equipped with two engine options: a 2.0T turbocharged + 48V mild hybrid and a 3.0T supercharged engine. The 2.0T engine is a high-power version, delivering a maximum power of 252 horsepower and a maximum torque of 380 Nm. The 3.0T supercharged engine provides 283 horsepower and 400 Nm of torque.

I've driven some luxury cars, including models like the Hongqi H9, and it's quite common for the co-pilot ambient light to not work. Don't worry, it could be due to several factors. The most likely issue is that the LED light strip itself is faulty—prolonged use can cause aging or burnout, especially on the co-pilot side, which is often exposed to direct sunlight and more prone to problems. Wiring is another key point. The H9's ambient lights are controlled by a computer, and if the control module's connector is loose or has poor contact, the signal won't reach the light. Additionally, a blown fuse is a strong possibility. There's a fuse box in the car—locate the fuse corresponding to the co-pilot light and check if it's blown, then replace it to test. The H9 is a domestic high-end car with a more complex ambient lighting system, so voltage instability or the installation of substandard accessories could also trigger malfunctions. I recommend not tampering with it yourself; instead, take it to a proper repair shop to inspect the control system and wiring. Spending a little money ensures safety, as the ambient light affects both mood and visibility during night driving. Fixing it early saves hassle.

How to Obtain the Annual Inspection Sticker for a 9-Year-Old Vehicle Exempt from Inspection?

That means for the 7th and 9th years when the vehicle is exempt from the inspection line, the annual inspection sticker does not need to be replaced either. This is because most annual inspection stickers are now electronic, unless you specifically need a paper sticker. You only need to log in to the Traffic Management 12123 APP and save the annual inspection sticker to your phone; there's no need to deliberately replace the sticker. Below is relevant information about how often the vehicle inspection sticker needs to be replaced: Motor vehicles should undergo safety technical inspections according to the following periods from the date of registration. 1. For passenger vehicles used for commercial operations: once a year within the first 5 years; once every 6 months after exceeding 5 years. 2. For cargo vehicles and large or medium-sized non-commercial passenger vehicles: once a year within the first 10 years; once every 6 months after exceeding 10 years. 3. For small and mini non-commercial passenger vehicles: once every 2 years within the first 6 years; once a year after exceeding 6 years; once every 6 months after exceeding 15 years. 4. For motorcycles: once every 2 years within the first 4 years; once a year after exceeding 4 years. 5. For tractors and other motor vehicles: once a year. 6. For school buses: once every 6 months. If a commercial motor vehicle passes the safety technical inspection within the prescribed inspection cycle, it does not need to undergo the safety technical inspection again.

How to Maintain a 30cm Distance on the Right Side During Parallel Parking?

The method to maintain a 30cm distance on the right side during parallel parking is as follows: 1. Parallel parking at 30cm: Generally, before entering the parking space, keep a distance of about 30–50cm from the side (position the right 1/3 of the car's hood over the parking line to maintain a distance of about 30–50cm between the car body and the parking line.) 2. This distance is for observing the parking position through the right rear mirror: This distance allows for observing the parking position and determining a reasonable reversing distance into the space. If the distance to the right is too wide, it may affect the positioning points for entering the parking space and, when reversing straight and turning the wheel fully to the right, the left wheel might cross the left warning line.

Can body filler be applied directly to car paint?

It's best to let the newly painted car dry indoors for a period of time before driving it out. Generally, avoid contact with water for two days after painting in high temperatures. Relevant paint repair precautions are as follows: 1. Primer: The base must be completely dry before applying clear coat, otherwise the paint surface may lose gloss. 2. Color paint: Quick repairs must use single-component color paint. 3. Clear coat: The spraying pressure should not be too high (2-2.5KPa). Let each coat sit for 1-2 minutes, depending on the surrounding temperature during spraying - lower temperatures require longer sitting times, while higher temperatures require shorter times. The spraying thickness should be 1.5-2 cm and not too thick, otherwise it may not dry easily. After applying clear coat, let it sit for 5 minutes before baking. 4. Baking: The UV lamp should be 20-25 cm away from the part. Too far away will slow curing, while too close will cause fast curing but also fast shrinkage, leading to wrinkles and loss of gloss. For convex, concave, and curved parts, adjust the lamp angle according to the shape without missing any spots. If there's a power outage or the lamp is turned off during UV baking, don't turn it back on immediately - wait a few minutes for the lamp to cool down before restarting. UV rays can harm eyes, so wear specialized protective masks or glasses during operation.
