The "res" and "set" buttons on the car steering wheel are mainly used for the cruise control function. Here are the meanings of res and set on a car: res: res stands for reset. It has two functions: the first is to restore the set speed after temporarily canceling cruise control, and the second is to accelerate to the set speed after setting the cruise control speed. set: set stands for set. It also has two functions: the first is to decelerate to the set speed after setting the cruise control speed, and the second is to set the current speed as the cruising speed. Here are some related explanations about "res" and "set": 1. How to use the Res button: When using cruise control on the highway to maintain a speed of 120, and then stepping on the brake to temporarily cancel cruise control, causing the speed to drop to 100, pressing the res button will automatically accelerate the car back to 120. Alternatively, after setting the desired speed in advance, pressing the res button will automatically accelerate the car to the set speed. 2. How to use the Set button: When using cruise control on the highway to maintain a speed of 120, and you want to reduce the speed to 100, you can release the accelerator until the speed drops to 100 and then press the set button, and the car will continue to drive at 100. If you are originally at 120 and have set the speed to 100, pressing the set button will automatically decelerate the car to 100.

How to Repair a Broken Air Conditioning Compressor?

Methods for repairing a broken air conditioning compressor include: 1. Adding an appropriate amount of Freon; 2. Replacing the power supply line clamp and using sandpaper to clean the surface of the compressor's wiring terminals; 3. Reorganizing the connecting pipes between the indoor and outdoor units to reduce the compressor's workload; 4. Timely replacement of aged air conditioning power lines. Causes of air conditioning compressor damage include: 1. Electromagnetic clutch failure or internal wear of the compressor; 2. Refrigerant leakage; 3. Compressor capacitor damage or other circuit faults. Working principle of the air conditioning compressor: 1. Extracting refrigerant from the low-pressure area, compressing it, and then sending it to the high-pressure area for cooling and condensation; 2. Dissipating heat into the air through the heat sink; 3. Transforming the refrigerant from a gaseous state to a liquid state, thereby increasing the pressure.

What does a mid-term facelift for a car mean?

Car mid-term facelift refers to making some minor changes to the exterior. Vehicle facelifts are generally divided into 3 stages: 1. Initial stage: Mainly addresses issues after the new car launch. These modifications are usually very necessary, so purchasing the initial version of the model is relatively cost-effective, as many problems are resolved after accumulating practical experience. 2. Mid-term: Mid-term facelifts typically involve retuning the car's engine performance, such as increasing horsepower, enlarging wheels, or even adding some equipment. 3. Final stage: When a car model is in its last 1 to 2 years before replacement, there will be a major facelift. Usually at this time, the highest trim version of this model will appear, with considerable exterior changes (but not fundamental ones), such as reshaping of headlights, taillights, front and rear fenders, and significant optimization of interior trim, etc.

Why Are Both the High and Low Pressure Pipes of the Car Air Conditioning Hot?

Car air conditioning low pressure pipe being hot is generally caused by a dirty or clogged expansion valve. Here is the relevant information: 1. Cause of the fault: The low pressure pipe of the car air conditioning is connected to the refrigerant radiator, which exchanges the heat generated by the air conditioning operation. If the expansion valve is blocked, the air conditioning will not work, and the heat generated by the air conditioning operation cannot be removed, leading to the low pressure pipe heating up. It is recommended to go to a repair shop for timely maintenance and resolution. 2. Air conditioning compressor: The air conditioning compressor is usually installed on the engine and driven by a belt (some are directly driven). After being cooled by the condenser heat dissipation pipe, it turns into a high-pressure, low-temperature liquid. Then, after being dehumidified and buffered by the liquid storage dryer, it flows to the expansion valve with relatively stable pressure and flow rate. After throttling and pressure reduction, it finally flows to the evaporator to achieve cooling.

How to Transfer Insurance When Buying a Used Car?

When purchasing a used car, you can choose to either change the policyholder or apply for cancellation and transfer of insurance. Below are the relevant details regarding used car insurance transfer: 1. Changing the policyholder: First, prepare the necessary documents including ID cards of both parties involved in the transfer, the new vehicle license, the motor vehicle registration certificate, and the original insurance policy. Then, visit the previous insurance company to fill out a 'Vehicle Transfer Application Form' to complete the transfer process. 2. Applying for cancellation: If the new owner is dissatisfied with the previous owner's insurance company or finds the transfer procedure too cumbersome, they can directly apply for cancellation to terminate the original insurance policy. When applying for cancellation, only the premium from the start of the insurance period to the cancellation date needs to be paid, and the insurance company will refund the remaining amount. After cancellation, the new owner can select a new insurance company and purchase a new policy for the vehicle.

What is the model number of the Wuling Rongguang alternator belt?

Wuling Rongguang B12 engine alternator belt model is 4PK850, where PK represents the tooth pitch=3.5mm, 4 indicates the belt has 4 wedge teeth, and 850 means the effective belt length is 850mm. Engine principle is explained below: 1. Explanation 1: The operating resistance of a car alternator relates to the rotor's excitation voltage and current. Greater excitation current results in higher power generation, correspondingly increasing the alternator's operating resistance. For common AC or DC alternators, when there's no output current, the winding essentially behaves like an iron block with bearings. 2. Explanation 2: Besides bearing friction, there's no other resistance. When the output is loaded, the rotor generates strong magnetic fields that interact with the stator coil poles, creating attraction. Greater magnetic field intensity leads to higher operating resistance, and heavier loads increase magnetic flux cutting resistance, meaning greater operational resistance.

Is the photo for driver's license medical examination the same as the one on the driver's license?

Is the photo for driver's license medical examination the same as the one on the driver's license? The answer is yes. Specific requirements are as follows: According to the "Road Traffic Safety Law of the People's Republic of China", the photo standard for applicants of motor vehicle driver's licenses should be: a 1-inch bareheaded photo of the license holder. Requirements for motor vehicle driver photos: The applicant must provide a straight-edged, front-facing, bareheaded color ID photo (half-body portrait) taken within 6 months prior to applying for a motor vehicle driver's license. The background must be white; red clothing is not allowed (as it affects stamping), women cannot wear earrings, photos with shawls are not permitted, men's hair cannot be too long, the facial image must be clear with rich layers and natural expression. The photo size should be 32mm×22mm, with head width between 14mm-16mm and head length between 19mm-22mm.
