What are the reasons why the Tiggo 5 key detection does not show a successful start?

Tiggo 5 key detection does not show a successful start for three reasons: dead battery, interference, or issues with the receiver. Below are the explanations and solutions for these causes: 1. Dead battery: If the remote control battery has been used for a long time, it may run out of power. Solution: In this case, you can only use the emergency start method first. Place the remote control close to the one-button start button to allow the car to start normally, then replace the battery as soon as possible. 2. Interference: If the remote key is too close to a mobile phone, it may sometimes be affected by the phone's signal, causing the dashboard to display that the key is not detected. Solution: Simply move the phone away to keep it at a distance from the key. 3. Receiver issues: When components such as circuits or sensors are damaged, the key may not be detected. Solution: Take the car for repairs.

How long does it take to pick up the 2021 Model 3?

It takes about two weeks to pick up the 2021 Model 3. Here are some precautions when picking up and inspecting the car: 1. Check the appearance: Inspect the exterior thoroughly. Walk around the car to check for any scratches, dents, or signs of rust on the chassis. 2. Check the production date: The vehicle also has a production date, usually marked on the nameplate outside the car. It's best to get a new car within three months or up to six months. Beyond this time, it is likely a test drive or exhibition car. 3. Check the engine compartment: Open the hood. The engine compartment of a new car is very clean and can be easily identified. Then start the engine to see if there are any abnormal noises or noticeable vibrations. 4. Check the interior: Enter the car to inspect the interior. Ensure it is clean, check the seats for scratches, and look for any dirt in the gaps. 5. Check the mileage and tires: The mileage of a new car usually does not exceed 50 kilometers. However, some dealers may tamper with the mileage. In that case, check the tires. New tires generally have deep tread patterns and may still have tread hairs on them.

What is the difference between Liuzhou Wuling and SAIC-GM-Wuling?

The difference between Liuzhou Wuling and SAIC-GM-Wuling lies in the fact that Liuzhou Wuling is a state-owned enterprise, while SAIC Wuling is a joint venture. Liuzhou Wuling Automobile Co., Ltd. (referred to as Wuling Group) was established in 1996. It is a large state-owned sole proprietorship enterprise authorized by the Guangxi government. Wuling is the registered trademark and brand of Liuzhou Wuling Automobile Co., Ltd., and this logo has been fully authorized to SAIC-GM-Wuling. SAIC Wuling is a large Sino-foreign joint venture automobile company jointly established by Shanghai Automotive Industry Corporation (Group), General Motors (China) Investment Co., Ltd., and Liuzhou Wuling Automobile Co., Ltd. The purpose of the joint venture between Liuzhou Wuling Automobile and SAIC-GM is to obtain the qualification license for selling cars, but the trademarks of Wuling Motors and Baojun Motors belong to Liuzhou Wuling and are assets of the Guangxi Zhuang Autonomous Region. Although SAIC-GM-Wuling is a joint venture, it only sells the two Chinese-made car brands "Wuling" and "Baojun," and does not sell joint venture foreign brand cars, which is also different from other joint ventures. The cars it produces use Wuling's brand, SAIC's technology, and General Motors' engines, but when they are finally launched, they still bear the original factory logo of Liuzhou Wuling, so SAIC-GM-Wuling is actually a domestic independent brand.
