Refrigerant cannot be added to a car's air conditioning system without vacuuming. If the vacuum is not properly performed, the air conditioning system will not function effectively. Moisture in the air can freeze and block the expansion valve during cooling, and the high-pressure gauge needle will continuously (violently) fluctuate. Below are specific details about car air conditioning systems: 1. Introduction: The car air conditioning device (air-conditioning-device), commonly referred to as car air conditioning. 2. Function: It is used to regulate and control the temperature, humidity, air cleanliness, and airflow within the car cabin to optimal conditions, providing a comfortable environment for passengers and reducing travel fatigue; it also creates favorable working conditions for the driver and plays a crucial role in ensuring safe driving as a ventilation device.

Where is the location to add windshield washer fluid for the 2019 Nissan Sylphy Classic?

2019 Nissan Sylphy windshield washer fluid refill location: 1. Near the right headlight in the front engine compartment, lift the blue or black cap marked with a windshield washer symbol to add fluid. 2. In northern regions, choose antifreeze-type washer fluid to prevent pipe freezing in winter; in southern areas, use washer fluid with insect-cleaning additives. 3. Dilution: Most purchased washer fluids require dilution - follow the instructions. The vehicle's washer tank capacity is approximately 1.5L, so use a 1.25L-1.5L container for mixing. 4. Refilling: Locate the washer fluid reservoir (marked with a windshield spray symbol) on the left side of the engine bay. Pour the diluted fluid until the liquid becomes visible below the MAX line, without overfilling.

What to Do If the Verna's Brake Discs Are Small?

Verna's small brake discs can be replaced. Here is relevant information about Verna's brakes: 1. Disc brakes have better heat dissipation than drum brakes, making them less prone to brake fade and failure during continuous braking. The thermal expansion of brake discs along the thickness direction is minimal, so heat-induced size changes do not increase the brake pedal travel. 2. Disc brake systems respond quickly and can perform high-frequency braking actions, making them more suitable for ABS system requirements. Disc brakes lack the self-energizing effect of drum brakes, resulting in more balanced braking force between the left and right wheels. 3. The superior drainage of disc brakes helps reduce poor braking performance caused by water or mud.

Will speeding on a ramp be captured by cameras?

Speeding on highway ramps can be captured by cameras, and it will result in a 12-point deduction. On roads with speed limit signs, you must control your speed within the designated range to avoid being photographed for speeding. The maximum speed limit on highways is 120 km/h. On sections with this limit, driving over 132 km/h is considered speeding. After entering the highway lanes, drivers must strictly adhere to the principles of 'lane discipline and separate lanes' and speed regulations. Choose the correct lane based on your speed, avoid crossing lines, driving on dividers, or occupying emergency lanes. Highways are equipped with special markings to indicate the distance between vehicles. These can be used to gauge the following distance from the vehicle ahead. Under normal conditions, the longitudinal spacing on highways should be slightly greater than the speed value in kilometers per hour.

Do I need to go in person to handle traffic violations?

All drivers' licenses subject to penalties require the holder to be present to accept the penalty. Relevant information: Article 50 of the "Procedures for Handling Road Traffic Safety Violations" stipulates that for violations recorded by traffic monitoring equipment, the party involved should promptly report to the traffic management department of the public security authority to accept the penalty. A warning or a fine of less than 200 yuan may be handled under a simplified procedure; fines of more than 200 yuan (not including) or revocation of the motor vehicle driver's license should be handled under the general procedure. Handling violations requires an ID card, as well as the driver's license and vehicle registration certificate. As for whether the vehicle owner needs to go in person, it can be determined based on the actual situation. Since 2019, the traffic management department has tightened the review process for handling violations, aiming to crack down on the illegal practice of trading driver's license points, so it is best for the vehicle owner to handle it in person.
