When to Use Hazard Warning Lights in a Car?

The following situations require the use of hazard warning lights in a car: 1. Vehicle breakdown: If your vehicle breaks down while driving, try to move it to the roadside or the emergency stopping lane on a highway. Turn on the hazard warning lights, place a triangular warning sign 150 meters behind the vehicle, call the police or request assistance, and ensure that the driver and passengers stay away from the faulty vehicle to avoid secondary collisions from passing vehicles. 2. Driving in the rain: Rain reduces visibility, making it harder to see other vehicles. In such conditions, turn on the hazard lights to alert other drivers of your presence. 3. Emergency malfunctions while driving: If an emergency occurs while driving, such as brake failure, turn on the hazard lights and headlights, and use the horn to warn pedestrians and other vehicles to move aside. Then, try to stop the vehicle safely. 4. Temporary parking: When temporarily parking on the road, especially in non-motorized lanes or borrowed lanes, turn on the hazard lights to alert passing vehicles and pedestrians for safety. The driver should not leave the vehicle casually, as this could lead to more severe consequences in case of an accident. 5. Traffic accidents: After a traffic accident, immediately turn on the hazard lights to warn passersby, then exit the vehicle to call the police or handle the situation. 6. Towing a faulty vehicle: When towing a faulty vehicle, both the towing vehicle and the towed vehicle should have their hazard lights on to alert other drivers and pedestrians, especially those behind, to avoid sudden lane changes or insufficient safety distances, which could lead to dangerous situations. 7. Performing emergency tasks: For urgent situations, such as transporting critically ill patients or handling emergency official duties, accelerate with caution and turn on the hazard lights to alert other vehicles and pedestrians for safety.

Should You Engage the Handbrake or Neutral First When Parking?

The correct parking procedure for an automatic transmission vehicle should be: press the brake → shift into gear → engage the handbrake → turn off the engine → shift into parking gear. In other words, after stopping, engage the handbrake first before shifting into neutral. Below is relevant information: 1. Auxiliary Brake: The professional term for the handbrake is the auxiliary brake. Unlike the main braking system, it uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, long-term use will reduce its effectiveness and increase the handbrake's travel distance. 2. Neutral Gear: Neutral gear typically refers to the state where the vehicle's gear lever is not engaged in any forward or reverse gear, completely disconnecting the transmission from the drive wheels. For manual transmissions, the neutral position is in the middle, while for automatic transmissions, it is marked with an "N".

What are the types of car engines?

Types of car engines are as follows: 1. According to the working method of the intake system: They can be divided into four types: naturally aspirated, turbocharged, mechanically supercharged, and twin-charged. 2. According to the piston movement method: They can be divided into reciprocating piston internal combustion engines and rotary piston engines. 3. According to the cylinder arrangement: They include inline engines, V-type engines, W-type engines, and horizontally opposed engines, etc. 4. According to the number of cylinders: They can be divided into single-cylinder engines and multi-cylinder engines. Modern cars mostly use three-cylinder, four-cylinder, six-cylinder, and eight-cylinder engines. 5. According to the cooling method: They can be divided into water-cooled engines and air-cooled engines. Water-cooled engines have uniform cooling, reliable operation, and good cooling effect, and are widely used in modern automotive engines. 6. According to the number of strokes: They can be divided into four-stroke internal combustion engines and two-stroke internal combustion engines. Four-stroke internal combustion engines are widely used in car engines. 7. According to the fuel supply method: They include carburetor engines, electronic fuel injection engines, and direct injection engines.

What Are the Reasons for Windshield Washer Not Spraying Water?

Common causes for windshield washer not spraying water include: insufficient washer fluid level; incorrect washer fluid selection leading to freezing in cold weather, which may crack the washer fluid reservoir; malfunction of the washer pump causing it to stop working; or faults in the washer tubing and nozzles preventing water spray. When the windshield washer fails to spray, consider the following aspects: 1. Washer pump burnout: The washer pump might be burnt out. To check this, keep the vehicle stationary, turn on the washer switch, and listen for the pump's sound in a quiet environment. If the pump doesn't operate, it certainly won't spray water to clean the windshield. 2. Empty washer reservoir: Pay attention to simple maintenance or operations. In fact, car manufacturers have detailed in the user manual some basic "issues" that owners can maintain themselves. If individuals learn and master these, such "unnecessary" "mistakes" can be avoided. 3. Wiring issues: Possible causes include wiring faults, blown fuses, or other circuit-related problems preventing the washer pump from functioning, hence no water spray. 4. Nozzle blockage: Nozzles may get clogged due to dust ingress, poor water quality, among other reasons. Of course, poor nozzle quality can also lead to no water spray.

What brand is CENTARA tires?

CENTARA is the Speedline tire brand of Shandong Zhongyi Rubber Co., Ltd. Shandong Zhongyi Rubber is a research and manufacturing enterprise specializing in the production of high-performance semi-steel radial tires, all-steel radial tires, steel wire rope core and fabric core rubber conveyor belts. It owns tire brands such as Leluchi, Speedline, JOYROAD, CENTARA, and ARDENT. The company's radial tires cover more than 500 models across 18 series, with SUV, UHP, and snow tires as the main products. The products are characterized by high cost performance, low carbon and environmental protection, quietness and comfort, and safety and reliability. The company possesses run-flat tire production technology and patented puncture-proof and leak-proof safety tire production technology. The products are sold throughout China and exported to more than 130 countries and regions, including Europe, America, Africa, Southeast Asia, the Middle East, the United States, Japan, Australia, and India. When using CENTARA tires in daily life, pay attention to the following points: Regularly check the tire surface for cracks, deformations, and other defects. Due to driving wear, the tread pattern grooves gradually become shallow. If the pattern is worn flat, it will lose its drainage and anti-slip functions, and the car's performance will be greatly reduced. Small cracks may seem insignificant, but they can be a hidden danger for tire blowouts at high speeds. In addition, immediately remove pebbles from the grooves. Try to park on flat ground. Avoid parking the car on roads with thick, sharp, or pointed stones. The car should not be parked near or in contact with petroleum products, acids, or other materials related to rubber deterioration. After parking, the driver should not turn the steering wheel, as this will accelerate tire wear. Do not splash water for cooling. In hot weather or during high-speed driving, tires are prone to overheating, and the air pressure will increase. At this time, you should stop to dissipate heat. It is strictly forbidden to deflate for pressure reduction or to splash water for cooling, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent use of brakes and sudden braking to prevent accelerated tread wear caused by dragging between the tires and the ground.
