Radar Ready means that the DRCC (Dynamic Radar Cruise Control) or speed cruise control is activated. The speed cruise control system can be operated using the control buttons on the right side of the steering wheel, with the far-right button being the speed cruise control switch. If you need to turn off the Radar Ready reminder, you can press this button to deactivate it. More related information is as follows: 1. Classification: Radar is divided into military and civilian types, but their common function is to determine the physical position of a target through radio waves. Military radar is used to search, monitor, and identify military targets, while civilian radar is mainly used for meteorological services, aviation, and ship traffic control. 2. Introduction: Radar, also known as 'radio location,' is an electronic device that uses electromagnetic waves to detect targets. Its principle is that the radar emits electromagnetic waves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the radar, the rate of change in distance (radial velocity), azimuth, and height. Radar is divided into military and civilian types, but their common function is to determine the physical position of a target through radio waves.

When the dashboard displays 'Radar Ready', my understanding is that the vehicle's radar system has completed its startup self-check and is now ready for use at any time. It's similar to how a smartphone loads programs upon booting up—after the vehicle is powered on, the radar takes a few seconds to self-test circuits and calibrate probes. This notification means you can normally activate functions like automatic braking or blind spot monitoring while driving. Personally, I always pay extra attention after washing the car or during rain or snow, making sure the radar probes aren't blocked by mud or water, otherwise the system may report errors. I recommend not rushing off immediately after starting the vehicle—wait five or six seconds until this prompt appears before driving. After all, a malfunctioning driver assistance system can be quite dangerous, especially when using adaptive cruise control on the highway.

What is the fuel consumption per 100 kilometers for a 1.5L naturally aspirated engine?

1.5L engine cars typically have a fuel consumption of 6-8 liters per 100 kilometers. When driving on highways at a speed of around 90 km/h, the fuel consumption is approximately 6.5L/100km; for urban and suburban roads, the combined fuel consumption is around 7.5 liters. Specific details are as follows: 1. Large displacement: Generally, a larger displacement means the engine releases more energy per unit time (converting chemical energy from fuel into mechanical energy), which also means better 'power performance.' It's like comparing a teenager to a healthy adult—the adult is naturally more efficient at physical labor. Therefore, SUVs and sports cars usually have relatively larger displacements. 2. Cylinder displacement: The working volume that the piston moves from the top dead center to the bottom dead center is called the cylinder displacement; if the engine has multiple cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is usually expressed in liters (L).

How to Handle Recalled Vehicles?

After a vehicle is recalled, it undergoes a series of inspections and repairs until there are no related safety issues or non-compliant equipment. Here is extended information about the vehicle recall system: 1. Introduction to the vehicle recall system: The vehicle recall system refers to the process where vehicles already on the market are found to have defects due to design or manufacturing issues, which do not comply with relevant regulations and standards and may lead to safety or environmental problems. 2. Manufacturer's actions after a recall: The manufacturer must promptly report to the relevant national authorities about the product issues, the causes of the problems, and the improvement measures, then submit a recall application. Upon approval, modifications are made to the vehicles in use to eliminate potential hazards. Manufacturers are also obligated to keep users informed about the situation, which is crucial for protecting consumers' legal rights. 3. According to the "Regulations on the Recall of Defective Automotive Products": Article 24 states that if a producer violates these regulations under any of the following circumstances, the product quality supervision department shall order corrections and impose a fine ranging from 1% to 10% of the value of the defective automotive products; any illegal gains shall be confiscated; in severe cases, the licensing authority may revoke relevant licenses.

Why Won't the Wiper Return to Its Original Position?

If the wiper does not return to its original position, you should check whether the wiper is stuck or has an open circuit; check if the hardware is sufficiently lubricated; and inspect whether the wiper rubber is aged or if there is dust or other foreign objects trapped between the rubber and the windshield. The inspection methods are as follows: 1. Check if the wiper is stuck or has an open circuit: After confirming that the motor is functioning properly, proceed to check other potential issues besides the motor, such as whether the wiper has an open circuit or is stuck. These are relatively simple checks. 2. Check if the hardware is sufficiently lubricated: If none of the above issues are present, inspect whether the hardware lacks lubrication, causing excessive friction and preventing the spring from automatically returning to its original position. Apply lubricating oil to the surface of the card. 3. Check if the wiper rubber is aged or if there is dust or other foreign objects trapped between the rubber and the windshield: If the wiper's return is obstructed, clean the wiper rubber and windshield with a damp cloth. Replace the wiper or rubber if necessary. 3. Reset method: There are reset contacts inside the wiper motor. After turning off the wiper, the motor continues to operate until it reaches the reset contacts, at which point the wiper stops working. This point is where the wiper blade is at the lowest position on the windshield.

What Chemicals Are Paint Strippers That Car Paint Fears?

Strong acidic or alkaline substances such as toilet cleaners and high-efficiency kitchen cleaners can initially cause the car paint to lose its luster and gradually corrode it. In severe cases, they may even corrode the car's body. Additional information is as follows: 1. Car paint is most afraid of paint strippers: Paint strippers can remove a wide range of coatings, including alkyd, nitrocellulose, polyurea-formaldehyde rubber-based vinyl, epoxy, polyester, polyurethane paints, exterior wall coatings, and powder coatings. They have extremely strong paint removal capabilities, making them the most feared by car paint. 2. The role of car paint: Car paint primarily protects the car body from corrosion and enhances the car's aesthetic appeal. It is also a way for many car owners to express their individuality.

What are the permissible vehicle types for a C2 driver's license?

A C2 driver's license only permits the operation of small and micro automatic transmission passenger vehicles, as well as light and micro automatic transmission cargo vehicles. Similar to the C1 license, it restricts driving to automatic transmission vehicles with no more than 9 seats and a length not exceeding 6 meters. In simple terms, a C2 license holder can only drive small automatic transmission cars and has no other permissible vehicle types. Not all automatic transmission vehicles are allowed under a C2 license. The application age for a C2 license is between 18 and 70 years old, meaning any citizen aged 18 to 70 can apply for a C2 driver's license. The C2 license is one of the more common driver's licenses, allowing only the operation of automatic transmission vehicles with no more than 9 seats and a length not exceeding 6 meters. [1], License code: C2, Application age: 18-70 years old, Permissible vehicle types: Small automatic transmission cars, Permissible vehicles: Small and micro automatic transmission passenger vehicles and light, micro automatic transmission cargo vehicles, Other permissible vehicle types: Only C2, no other permissible vehicle types, Annual physical examination: Not required for those under 60 years old, Requirements for test vehicles: Light automatic transmission ordinary cargo vehicles with a length of no less than 5 meters, or small automatic transmission ordinary passenger vehicles with a length of no less than 4 meters, or automatic transmission cars with a length of no less than 4 meters.

Will leaving a small gap in the window be affected by rain?

If it rains heavily, water may accumulate under the floor on the passenger side. Specific details are as follows: 1. Water accumulation inside the car: It is recommended to check before driving. If there is already water accumulation, use a dry towel to absorb and drain the water. Prolonged water accumulation can cause rust and corrosion on the chassis steel plate. 2. Handling water ingress in the car: If only rain has entered the car, the impact is minimal. Simply open the windows fully on a sunny day to air it out. If water enters the cabin, the repair process mainly involves removing the accumulated water. There are several rubber seals at the bottom of the vehicle chassis. Opening these seals can drain the water from the cabin. However, since the interior floor mats are highly absorbent, they should be removed and placed in a spacious area to facilitate evaporation of the moisture.
