What lights should be turned on when driving straight at night?

When driving straight at night, low beam headlights should be used. If the road ahead is completely dark with no road lighting facilities, high beam headlights should be turned on. If you encounter an oncoming vehicle, switch to low beam headlights in advance, and after passing the vehicle, decide whether to turn on the high beam headlights again based on the situation. When driving straight through an intersection at night, low beam headlights should be used. There is also a suggestion to alternately use high and low beam headlights as a signal. When passing through an uncontrolled intersection without traffic signals, you should slow down and alternately use high and low beam headlights as a signal. When overtaking at night, turn on the turn signal in advance and observe the vehicles behind. If the following vehicle is too close, it is not recommended to use the turn signal for overtaking, as this may easily catch the following vehicle off guard. In case of rainy or foggy weather with low visibility, the correct approach is to turn on the width marker lights, front and rear fog lights, and hazard warning lights. Note that fog lights are very bright and have a strong warning effect, so they should not be turned on during clear nights.

What are the precautions for car sound insulation?

Precautions for car sound insulation: 1. Install vibration-damping pads and moisture-proof sound blankets inside the cabin to reduce resonance caused by chassis components during high-speed driving and minimize road noise transmission from tire rotation. 2. Apply velvet sound-absorbing blankets on door trims and install door sealing strips to enhance airtightness, thereby reducing resonance and wind noise at high speeds. 3. Spray sound insulation materials on the front and rear wheel fenders to decrease abnormal sounds from shock absorbers during driving and suppress impact noises between tires, road surfaces, and metal panels. 4. Attach fireproof sound insulation blankets on the engine hood to absorb engine operation noise. Reinforce the stiffness below A, B, and C pillars and strengthen the rear seat side panels to improve the structural rigidity of the body and effectively reduce noise. 5. Adhere a layer of heat-insulating and soundproof cotton on the cabin ceiling to effectively block intense sunlight, prevent rapid temperature rise inside the cabin, and reduce resonance from roof panel vibrations.

What Causes the Abnormal Noise from the Chassis After a New Car Shuts Off?

Here are the specific reasons for the abnormal noise from the chassis after a new car shuts off: 1. Disc Brake Malfunction: When the vehicle is driven at low speed on a flat road, irregular intermittent noises occur at the wheel hub area. The noise slightly intensifies as the speed increases but remains unchanged during uphill, downhill, or turning. The noise worsens when driving on uneven roads and reduces or disappears when the brake pedal is pressed. During a stationary inspection, rotating the wheel back and forth can reproduce the noise. This is caused by damage, deformation, or detachment of the brake shoe support plate, damping spring plate, or guide plate of the disc brake, which increases the gap between the brake shoe and the caliper support frame, leading to collisions and noise. Visit a repair station to fix deformed parts or replace detached ones. 2. Front Suspension Ball Joint Malfunction: When driving at low gear on bumpy roads, continuous noise is heard from the front axle area. The worse the road condition, the louder the noise, which intensifies with speed. After stopping, forcefully shaking the front of the vehicle will produce noise. On flat roads, irregular intermittent noises resembling the sound of metal breaking may occur from the front axle. This is due to excessive clearance between the ball joint and its socket, causing severe looseness. Since the ball joint socket is a sealed structure and cannot be disassembled, replacement at a repair station is the only solution. 3. Front Wheel Shock Absorber Malfunction: On flat roads, slight noise from the front of the vehicle can be heard, intensifying during sharp turns. During a stationary inspection, pressing down on the front of the vehicle to make it rebound up and down will produce noise, which becomes louder with more force. The vehicle also feels less elastic and not as smooth. This usually happens when the vehicle is frequently driven on rough roads with poor maintenance, leading to shock absorber oil leakage and damage. Depending on the severity of the damage, repair or replacement at a repair station is necessary.

What Do You Need to Prepare for Riding a Motorcycle on the Highway?

To ride a motorcycle on the highway, you need to prepare a driver's license and a helmet, and the speed must not exceed 80 kilometers per hour. Wearing a Helmet: When riding on the highway, you must wear a helmet. This is a mandatory requirement under traffic safety laws. If you are caught riding without a helmet, you will be stopped and fined by traffic police. Additionally, carrying passengers on the highway is strictly prohibited. Speed Must Not Exceed 80 km/h: The speed of the motorcycle must not exceed 80 kilometers per hour, and you must ride on the right side of the road, maintaining a speed between 70 and 80 kilometers per hour. Exceeding this limit will result in penalties from traffic police. Possessing a Motorcycle Driver's License: You must have a valid motorcycle driver's license to ride on the highway. Although many people may not choose to obtain a motorcycle license, it is mandatory for highway riding. Using other types of motor vehicle licenses is not permitted. If caught driving without the proper license, you will face penalties, and in severe cases, may even have 12 points deducted from your license.

Do I Need to Drive the Car for New Vehicle Annual Inspection?

New vehicles need to be driven for annual inspection. Vehicle annual inspection refers to a mandatory test for every vehicle that has obtained an official license plate and registration certificate, equivalent to an annual physical examination for the vehicle according to the "Technical Conditions for Motor Vehicle Operation Safety." Inspection time requirements: Small and micro non-operational passenger vehicles are exempt from inspection for the first 6 years. After 6 years but less than 10 years, they must be inspected every two years; after 10 years but less than 15 years, they must be inspected annually; after 15 years, they must be inspected every 6 months. Operational passenger vehicles must be inspected annually within the first 5 years; after 5 years, they must be inspected every 6 months. Trucks and large and medium-sized non-operational passenger vehicles must be inspected annually within the first 10 years; after 10 years, they must be inspected every 6 months. Imported vehicles, like other vehicle types, can undergo regular inspections at any inspection station. Inspection precautions: Vehicles that fail the inspection must be repaired within a specified period. If they still fail after the deadline, the vehicle management office will confiscate their license plates and registration certificates, prohibiting further use. Vehicles that do not undergo inspection without reason or fail the inspection are not allowed to drive on the road or transfer ownership. Vehicles that meet the scrapping conditions or exceed the prescribed service life will not be inspected, and their license plates and registration certificates will be revoked, with their files canceled and the vehicles scrapped.

How to Display the Tire Pressure Monitoring in Nissan Qashqai?

Nissan Qashqai's tire pressure monitoring display requires a period of normal driving before it appears. Press the menu button on the left side of the steering wheel to switch to the tire pressure page, and it will be displayed on the trip computer. There are three common methods of tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. When the tire pressure is too low or there is a leak, the system will automatically alert. Indirect Tire Pressure Monitoring: When the air pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor air pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a 4-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the defect of indirect systems not being able to detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires like a direct system.
