What is the reason for the hard and ineffective braking of the Hyundai ix35?

How often should a new car be serviced?

Generally, a new car should be serviced every 3 to 5 months or after driving 3,000 to 5,000 kilometers. Car maintenance items include replacing engine oil, oil filters, transmission oil, spark plugs, air conditioning filters, air filters, brake fluid, etc. In addition to these, maintenance also involves the inspection and maintenance of dozens of items across multiple systems such as the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires. Precautions before servicing a new car include: 1. When driving downhill for a long distance, pay attention to controlling the speed and do not suddenly use engine resistance to decelerate; 2. Do not overload, and also pay attention to checking tire pressure, coolant, and brake fluid.

How to Lower the Rear Seat Headrest in Mercedes-Benz GLC?

The function of a car headrest is to effectively protect the head and neck of occupants in the event of a collision, reducing injuries to the neck area. In addition to enhancing driving safety, car headrests also serve a decorative purpose. The method to lower the rear seat headrest in a Mercedes-Benz GLC is as follows: 1. In the backrest seat, the headrest can be separated from the backrest to adjust the height and angle of the headrest. 2. Manual adjustable headrests can only be adjusted in height, while automatic adjustable headrests can be adjusted in two dimensions automatically. The correct way to use a car headrest is as follows: 1. Adjust the angle between your body and the seat correctly, keeping your back as upright as possible. A gentle angle between the neck and the body can reduce the severity of injuries in a rear-end collision. 2. The distance between the head and the car headrest should be as small as possible, with a maximum limit of 4 centimeters, to provide cushioning for the neck during a rear-end collision. 3. Adjust the height of the car headrest correctly. The car headrest should be installed at least parallel to the top of the ears or approximately 8.89 centimeters below the occupant's head. After adjusting the car headrest, secure it firmly to prevent it from shaking.

How many kilometers should the spark plugs of a Corolla be replaced?

The spark plugs of a Corolla should be replaced every 80,000 kilometers. Methods to determine if spark plugs are damaged: Remove the spark plugs and observe them. The condition of the spark plugs can be judged based on their appearance and color. Normal spark plugs have insulator skirts and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm, and no signs of electrode burn. If the spark plugs are covered with oil or deposits but are not damaged, they can continue to be used after cleaning off the oil and deposits. If the spark plugs are severely damaged, with signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plugs with new ones. Additionally, if the spark plugs appear black as if smoked, it indicates that the wrong heat range was selected or the air-fuel mixture is too rich, with oil rising up.

What is the method for removing and installing the spark plugs in a Skoda Octavia?

Skoda Octavia spark plug removal and installation method is: 1. Wait for the engine to completely cool down, open the hood and unplug the high-voltage coil connector; 2. Use a 10mm socket to remove the fixing bolts, then take off the high-voltage coil to expose the spark plugs; 3. Select an appropriate socket size according to the spark plug nut, turn counterclockwise to loosen, then use a magnetic rod to extract the spark plug. Spark plugs, commonly known as ignition plugs, function by discharging the pulsed high-voltage electricity sent through the high-voltage wire, breaking down the air between the two electrodes to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. The Skoda Octavia measures 4675mm in length, 1814mm in width, and 1460mm in height, with a wheelbase of 2686mm. It is equipped with a 5-speed manual transmission and has a top speed of 185 kilometers per hour.

How to Cool Down the Air Conditioner in the New Passat?

Passat's air conditioning cooling method is as follows: You can choose to press the auto button or the AC button. When the light is on, it indicates that the air conditioner has been activated. Then, use the temperature adjustment rotary knob to set the desired temperature. Car air conditioning refers to the air conditioning device installed in a vehicle, capable of cooling, heating, ventilating, and purifying the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and enhancing driving safety. The four cyclic processes of car air conditioning are as follows: 1. Compression process: The compressor inhales low-temperature and low-pressure refrigerant gas from the evaporator outlet, then compresses it into high-temperature and high-pressure gas, which is discharged from the compressor. 2. Heat dissipation process: The high-temperature and high-pressure superheated refrigerant gas enters the condenser. Due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid, releasing a large amount of heat. 3. Throttling process: The refrigerant liquid with higher temperature and pressure passes through the expansion device, causing its volume to increase, and its pressure and temperature to drop sharply, discharging from the expansion device in a mist form (fine droplets). 4. Heat absorption process: The mist-like refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into a gas.

What engine does Haval use?

Haval adopts the GW4G15 series engine independently developed by Great Wall, which is a domestic engine. All models under the Haval brand use this series of engines. For example: the Haval F7x engine model is GW4C20B, a 1.5T version engine with a maximum power of 124KW, maximum torque of 285Nm, and maximum horsepower of 169. The 2.0T version engine has a maximum power of 165KW, maximum torque of 385Nm, and maximum horsepower of 224. For daily maintenance of Haval engines, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected according to the additional devices of the intake and exhaust system and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid failures, change the oil regularly according to usage conditions and keep the oil volume moderate. When engine oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, it may burst the filter element or open the safety valve, allowing oil to pass through the bypass valve and bring dirt back to the lubrication parts, accelerating engine wear and internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder wall, mixing with metal powder from part wear to form sludge. When the amount is small, it suspends in the oil; when large, it precipitates from the oil, clogging the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.
