Why is there no sound when playing songs via Bluetooth connection between car and phone?

Vehicle connected to phone via Bluetooth playing songs without sound is due to the car multimedia system volume or phone volume not being turned on. Here are specific details about car Bluetooth usage: 1. Activation method: Generally, car Bluetooth doesn't have physical on/off buttons in the vehicle, so all operations need to be performed through the central control screen. 2. Precautions: When connecting, make sure both devices' Bluetooth are set to discoverable mode. Since Bluetooth transmission has distance limitations, the phone shouldn't be placed too far from the car Bluetooth.

What is the tire pressure after being punctured by a nail?

Tire pressure drops below 1.7bar after being punctured by a nail. Hazards of low tire pressure: Low pressure increases tire body deformation, leading to cracks on the sidewalls and causing flexing movements. This results in excessive heat generation, accelerating rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area with the ground, speeding up shoulder wear. Hazards of high tire pressure: Excessive pressure overextends the tire cords, reducing the tire body's elasticity. This increases the load on the vehicle while driving, and may cause a blowout upon impact. High pressure also accelerates tread wear and reduces puncture resistance.

What Are the Tips When a Car Runs Out of Gas?

Here are some tips when a car runs out of gas: Turn off unnecessary devices: The first thing to do is to turn off devices such as the car charger, air conditioning, radio, navigation, and music in the car. These devices actually consume a significant amount of power, and turning them off can reduce fuel consumption. Reduce braking and avoid driving at low speeds: Braking itself doesn’t consume much fuel, but slowing down and then speeding up again does. Driving at very low speeds is similar to idling, and idling is highly fuel-inefficient. Drive at the most fuel-efficient speed: The so-called fuel-efficient speed refers to maintaining a speed of 90 km/h when driving on highways, and 60 km/h on regular roads while complying with traffic rules. However, there should be some flexibility. For example, cars with smaller engine displacements will have a lower most fuel-efficient speed compared to standard-displacement models, while cars with larger displacements will have a slightly higher most fuel-efficient speed. Keep the windows closed: When driving at the fuel-efficient speed, opening the windows will undoubtedly increase wind resistance. Greater wind resistance means the car is more affected by air resistance, requiring more power and thus consuming more fuel. It’s best to keep the windows closed and use the air conditioning moderately to ensure proper air circulation inside the car.

What Does Tire Noise Sound Like?

Tire noise is generated by the friction between the tires and the road surface when the vehicle is driving at high speeds. The intensity of tire noise depends on road and vehicle conditions—poorer road conditions result in louder tire noise. Additionally, the sound of tire noise differs between asphalt and concrete road surfaces. Below is relevant information about tire noise: 1. When tires cause a resonant humming sound, it indicates certain issues with the vehicle; 2. Possible reasons include the vehicle not having undergone a four-wheel alignment or a poorly performed alignment, leading to uneven wear on the tires and "tire cupping." It could also be due to improper tire replacement, causing bearing problems. Another possibility is engine resonance due to carbon buildup contamination, resulting in abnormal humming sounds from the vehicle.

How to Use the Car Heater?

After starting the car, wait approximately 8-15 minutes for the water temperature to reach normal operating levels. At this point, you can turn on the heating system and adjust the air conditioning circulation mode to internal circulation. Reason why using the heater doesn't consume extra fuel: The car heater doesn't require separate equipment to operate. It utilizes the engine's heated coolant by redirecting its circulation route into the cabin to produce warm air. Essentially, this can be considered waste heat utilization, as this heat would otherwise be expelled outside the vehicle regardless. Correct method for using the car heater: First start the engine for preheating. When the temperature gauge needle reaches the middle position, turn on the heater while setting the air circulation to external mode. Wait for 2-3 minutes until the cold air inside the cabin is expelled, then switch the air circulation to internal mode.

How to Check Vehicle Information When Buying a Used Car?

When buying a used car, you can check the vehicle information through the Traffic Management 12123 app. Here are the precautions for purchasing a used car: 1. Check the vehicle license: Verify whether the patterns on the front and back pages of the license match when combined, and check if the license photo and chassis number match the vehicle. 2. Check the vehicle insurance: Confirm that the chassis number and engine number on the insurance policy match those on the vehicle license, and ensure the insurance is still valid. 3. Check the vehicle registration certificate: Inspect whether the font on the registration certificate matches that on the vehicle license, and verify that the chassis number and engine number are identical to those on the license. Check if the manufacturing date and registration date align with the dealer's description, and review the registration history for frequent transfers within a short period.
