Lack of maintenance in the braking system, with excessive impurities in the brake master cylinder. Vehicle overload leading to brake failure. Improper operation causing mechanical failure, such as prolonged downhill braking. Excessive free travel of the brake pedal or excessive clearance in the brake, poor contact of the brake shoe friction lining, severe wear, or oil contamination. Symptoms of automotive brake failure include: 1. Excessive travel of the brake pedal, resulting in delayed braking response. 2. Very low or complete loss of braking efficiency, leading to increased stopping distance. 3. When stepping on the brake pedal, it feels neither soft nor hard, but the braking performance is still poor.

How to Press the Clutch Steadily?

Clutch pressing method: First, press the clutch pedal down with the ball of your foot. When it reaches the semi-engaged state, keep your heel on the ground. If the vehicle speed increases, press the clutch slightly; if the speed decreases, lift the clutch slightly. At the semi-engaged state, keep your heel on the ground, stabilize, and then use the brake to control the speed by lifting or pressing. Avoid pressing the clutch unless the vehicle is at low speed. The clutch is located in the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. During driving, the driver can press or release the clutch pedal as needed to temporarily disconnect or gradually engage the engine and transmission, thereby cutting off or transmitting the engine's power to the transmission.

What are the signs before an engine blowout?

Signs before an engine blowout include: excessively high engine block temperature, with surface temperature exceeding 90 degrees Celsius; reduced driving power; abnormal noises from piston-cylinder friction, with the frequency of the noise increasing as the engine speed rises. Engine blowout occurs when the temperature is too high, causing the piston to expand and get stuck in the cylinder, leading to engine failure. In severe cases, due to excessive pressure and the piston being unable to move, flames may erupt. Solutions for engine blowout: Ensure the engine is in a cooled state and turned off. Remove the radiator cap to confirm the engine is cool. Open the drain plug at the bottom of the radiator to let the coolant flow into a bucket. Close the drain plug and fill the radiator with water. Start the engine and turn on the heater control system. Add cooling system cleaner and let the engine idle for 30 minutes. Turn off the engine and let it cool for 5 minutes. Drain the liquid from the radiator, close the drain plug, fill the radiator with water, and let the engine idle for 5 minutes.

Where is the air filter located in the Lavida?

The Lavida's air filter is located on the right side of the engine compartment. It is generally recommended to inspect or clean it every 5,000 kilometers, and consider replacement every 10,000 to 20,000 kilometers depending on its condition. If owners wish to replace the air filter themselves, they must purchase the exact model specified for the vehicle and preferably choose an air filter with tightly arranged filtration material. The air filter is a device that captures dust from gas-solid two-phase flow through the action of porous filtration materials, thereby purifying the gas. The Lavida's body dimensions are 4670mm in length, 1806mm in width, and 1474mm in height, with a wheelbase of 2688mm.
