Phone issue: The connected phone may have a problem, requiring a restart or factory reset of the phone. 2. System issue: The car's infotainment system may have a problem, requiring a restart or factory reset of the system. Below is an introduction to in-car Bluetooth: 1. Working principle: The in-car Bluetooth player can connect to the car's Bluetooth system, receive Bluetooth signals from the phone, and convert them into FM signals for sound playback. 2. Function: The function of in-car Bluetooth is to automatically recognize mobile phones, enabling connection without cables or phone mounts; the driver can control the phone without touching it, even keeping both hands on the steering wheel, and use voice commands to answer or make calls.

Can a Car Still Be Driven After Being Submerged While Stationary?

It is not recommended to continue driving a car that has been submerged while stationary. When a car is submerged while stationary, after timely repairs at a service station, the engine oil, transmission fluid, gasoline, power steering fluid, and other lubricants will be circulated, cleaned, and replaced. Additionally, dirt and sand on external components will be cleaned. There is generally no significant damage to the mechanical parts, and the car's normal driving functions will not be affected. If water enters the engine during submersion and causes it to stall, issues may arise with the engine. Internal components such as pistons, connecting rods, and valves may require major repairs. The owner must first confirm whether water has entered the engine's intake system by checking if the air filter has been soaked. If the air filter is dry, the engine can be safely restarted. However, if the air filter is completely soaked and there are signs of water in the intake pipe, water may have entered the intake manifold. Although the engine may not necessarily be damaged, it is strictly prohibited to start the engine in this situation. Instead, arrange for towing assistance. After the vehicle is delivered to a 4S shop, a comprehensive water-related fault inspection should be conducted to identify and address all potential issues, ensuring no hidden threats to future driving safety.

Why Do the Tail Lights Stay On After the Car Is Turned Off?

If the tail lights remain on after the car is turned off, it is due to the "Follow Me Home" feature. Under normal circumstances, the lighting delay of this feature does not exceed 5 minutes, and it does not depend on the lighting state before the car was turned off. Instead, it follows a fixed lighting pattern. Regardless of the position of the lighting switch before the car was turned off, the Follow Me Home feature will default to turning off the high beams and daytime running lights, only keeping the low beams on. Depending on the vehicle model, the definition may vary. For most Chinese-market models, the Follow Me Home feature defaults to illuminating both headlights while turning off the tail lights. However, for some Korean-made vehicles, both headlights and tail lights may remain on simultaneously. Apart from the Follow Me Home feature, there is another less common scenario where the headlights turn off normally, but the tail lights stay on persistently or only one tail light remains lit while all other lights are off. This is also a normal phenomenon, known as the parking light. The parking light was originally a mandatory regulation in certain U.S. states, requiring all vehicles to keep their tail lights on after being parked and turned off at night to alert pedestrians or other vehicles in areas without street lighting.

What Causes the Car Window Glass to Tilt to One Side When Rolling Up?

Here are the reasons why the car window glass tilts to one side when rolling up: Window regulator malfunction: A faulty regulator or aging motor may result in insufficient power, causing the window to fail to roll up properly when encountering slight resistance. Damaged rubber guide channel: Prolonged use of the vehicle can cause the rubber guide channel of the window glass to deteriorate due to rubber aging or dust accumulation, leading to slow window movement or stopping at a certain position. Some window glasses may tilt when rolling up. Loose window fixing screws: This is often accompanied by unusual noises when the window is being rolled up.
