When the ACC detects that the radar is obstructed, the radar malfunctions, or related systems (such as ESC) fail, the cruise status indicator on the dashboard turns orange, and a message appears indicating that the radar is obstructed or the adaptive cruise system has malfunctioned. Information about ACC: 1. How ACC works: When the distance to the vehicle ahead is too small, the ACC control unit can coordinate with the anti-lock braking system and the engine control system to apply appropriate braking to the wheels and reduce the engine's output power, ensuring the vehicle maintains a safe distance from the vehicle in front. 2. When to use ACC: The adaptive cruise control system typically operates when the vehicle speed exceeds 25 km/h. When the speed drops below 25 km/h, the driver needs to take manual control. Through system software upgrades, the adaptive cruise control system can achieve a "stop/start" function to handle frequent stops and starts in urban driving conditions.

Can a Spare Tire Be Used as a Regular Tire?

Spare tires cannot be used as regular tires because they are designed for emergency use only and are not intended for long-term use. After replacing a flat tire with a spare, you should promptly visit a repair shop to replace it with a regular tire. Below is a detailed introduction about car spare tires: 1. Overview: A spare tire refers to a backup tire for a car, and its specifications are usually the same as the original car tires. However, some vehicles use spare tires with special-colored rims, compact spares, folding spares, or run-flat tires to remind the owner to inspect and replace the faulty tire promptly. 2. Function: Compact spares, folding spares, and run-flat tires also help save storage space inside the vehicle. The maximum speed when using a spare tire is lower than that of a standard tire, and it is advisable to replace it with a standard tire as soon as you reach your destination. This is often indicated with prominent multilingual labels.

What are the benefits of applying film to the windshield?

Functions of applying film to the car windshield: 1. Sun protection: Primarily for sun protection and UV resistance. The windshield has a large exposed area and receives the most UV radiation. Applying film can effectively block UV rays, safeguarding the health of the driver and passengers. 2. Heat insulation: Many practical tests have proven that windshield film can indeed block a portion of heat, with relatively noticeable effects. However, this requires the use of high-quality film. 3. Anti-glare: During the day, the glaring sunlight can easily cause dazzle; applying film can slightly improve visibility. At night, the strong lights from oncoming vehicles can also produce blinding glare, especially during rainy nights when the lights become more chaotic. Windshield film can effectively reduce this blinding glare.
