What are the reasons for no sound in the Envision's audio system?

2 Answers

Envision's audio system has no sound due to: 1. Dead battery: If the car battery is dead, the audio system will naturally have no sound. This situation can be resolved by charging the battery; 2. Audio plug disconnected: If the audio plug falls off when the car passes over bumpy roads, it will also cause the audio system to have no sound; 3. Volume not turned up or in mute mode: Simply increase the volume or turn off the mute mode of the audio system; 4. Incompatible aftermarket audio: If the audio system is modified later, it may have no sound due to quality issues or incompatibility. In this case, it is necessary to go to a repair shop for inspection.

Having driven for so many years, I've encountered quite a few instances where the car audio suddenly went silent. First, check if the volume setting is too low or if the mute button was accidentally pressed—this is the most commonly overlooked issue. Next, verify whether the audio source is correctly selected, such as being in Bluetooth mode but forgetting to connect your phone. Additionally, loose plugs or poor wire connections are frequent culprits, especially after the car experiences bumps that disrupt connections. If the system freezes, try turning off the engine for a few minutes and restarting the car—this simple step has resolved the issue many times for me. Moreover, software glitches can cause sound loss, particularly when delayed system updates introduce bugs. For prevention, I regularly clean the interior to keep ports free of dust buildup, a habit that has significantly reduced such problems. If the issue persists, it might be a blown fuse or faulty speakers, in which case I recommend visiting a professional repair shop to avoid disrupting your daily navigation or music enjoyment.

How to reset the tire pressure light on the new Lingpai?

The tire pressure light on the new Lingpai can be reset by locating and holding down the tire pressure reset button. Tire pressure reset is an operation performed on the tire pressure monitoring system after addressing any tire pressure issues. Steps to reset the tire pressure on the new Lingpai: First, turn on the ignition, then press and hold the tire pressure monitoring reset button. Release the button after hearing a "beep" sound. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally turn off the warning light on the dashboard, completing the tire pressure reset. Hazards of low tire pressure: Increased friction with the road surface, leading to higher fuel consumption; Heavier steering wheel, tendency to drift, and other factors detrimental to driving safety; Increased movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduced functionality of the cords and rubber, leading to delamination or cord breakage, excessive friction with the rim causing damage to the bead area, and abnormal wear; Exponentially increased friction between the tire and the ground, rapid rise in tire temperature, softening of the tire, and sharp decline in strength. High-speed driving may lead to tire blowouts; Increased deformation of the tire body, prone to cracks on the sidewalls, along with flexing movements causing excessive heat, accelerating rubber aging, fatigue of the cord layers, cord breakage, and increased contact area with the ground, accelerating wear on the tire shoulders.

Is it harmful to the car if the window is left open and it rains?

Leaving the car sunroof open during rain can indeed be harmful to the vehicle. Here is the relevant information: 1. Interior moisture: This can lead to dampness inside the car, making the interior upholstery prone to mold and mildew, and damaging leather seats. 2. Significant water ingress: If a large amount of water enters, the excessive moisture can cause electrical circuit short circuits. If water enters the engine, it may render the engine unusable. When driving in the rain, ensure all doors, windows, and the sunroof are tightly sealed to prevent rainwater from entering and causing dampness inside the vehicle. 3. Rainy driving precautions: (1) If you forget to close the sunroof and rainwater enters, the first step is to dry the interior. Wipe up any standing water and ventilate the car. Replace seat and floor mats, and dry them in the sun when possible. You can also place a dehumidifier box inside the car to absorb moisture. (2) For leather items that get wet, use towels or paper towels to dry them as much as possible. However, avoid exposing leather items to direct sunlight; let them air dry naturally. Also, wipe away any water near electrical circuits to prevent prolonged exposure to moisture, which could lead to short circuits or even electric shocks. After the car has been exposed to rain, ensure good ventilation inside the vehicle once the weather clears, and check if the drainage channels on the windshield are clear.

Consequences of Not Performing Wheel Alignment?

The consequence of not performing wheel alignment is that the vehicle will continuously pull to one side, which may lead to more serious safety accidents. Generally, wheel alignment is performed when the vehicle starts to pull to one side. After driving for a period of time, it is inevitable that the tire angles will become abnormal due to road bumps and component wear, causing the vehicle to drift. Methods to determine if wheel alignment is problematic: 1. Driving in a straight line: Choose a flat and straight road, ensure that the tire pressure of all four tires is consistent, straighten the steering wheel, then release the steering wheel and press the accelerator. If the vehicle can drive straight, it means the wheel alignment is fine; if the vehicle slightly drifts to the left or right with a minimal angle, it can be ignored; if the drift is severe, it indicates a wheel alignment issue. 2. Check for uneven tire wear: Owners should regularly inspect their tires, as they are the only part of the vehicle in contact with the ground. If the tires show uneven wear—one side is heavily worn while the other remains in good condition, also known as "tire cupping"—it indicates abnormal wheel alignment. Under normal circumstances, tire wear should be relatively even. 3. Lift the vehicle and shake the tires: Use a jack to lift the vehicle, leaving the tires in an unsupported state. Place your hands on the top and bottom or left and right of the tire, then apply slight force to shake the tire up and down or left and right. If the tire wobbles, the bearing may be damaged; bearing damage is also a sign of wheel alignment issues.

How to Rematch the Tire Pressure Monitoring System on the Envision?

The method to rematch the tire pressure monitoring system on the Envision: Start the vehicle, locate and press the SET button on the left side of the multifunction steering wheel, then press the checkmark button on the right side of the multifunction steering wheel to confirm the operation. Once matched successfully, the tire pressure display on the central dashboard will return to normal. There are three commonly used tire pressure monitoring methods: Direct Tire Pressure Monitoring: The direct tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. It transmits the pressure information from inside the tire to a central receiver module via a wireless transmitter, then displays the data for each tire's pressure. The system automatically alerts when the tire pressure is too low or there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. The indirect tire pressure warning system essentially relies on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a four-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of the indirect system, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data of the actual pressure in all four tires as the direct system does.

How many kilometers do brake pads need to be replaced?

Brake pads generally need to be replaced every 30,000 to 50,000 kilometers. The driving conditions of each vehicle and the driving habits of each driver will affect the service life of the brake pads. The thickness of new brake pads is usually about 1.5cm. As they wear down through daily friction, when the thickness of the brake pads is only about 1/3 of the new ones, the frequency of inspection should be increased, and new brake pads should be prepared for replacement at any time. There are small raised indicators on both sides of the brake pads. When the brake pads are level with these indicators (2-3mm), it means they have reached their limit and must be replaced. Method for replacing brake pads: Gather all the necessary tools and parts, loosen the wheel bolts by half a turn, but there is no need to completely remove them. Use a jack to lift one side of the vehicle at the designated lifting point. The vehicle only needs to be lifted until the wheel that requires brake pad replacement is slightly off the ground. Then, all the wheel bolts can be unscrewed and the wheel can be removed. Place the removed wheel under the brake disc to prevent the vehicle from falling in case the hydraulic jack loses pressure, which could cause injuries. To replace the brake pads, only the two bolts securing the brake caliper need to be removed. After loosening these two bolts, the brake caliper can be taken off. Since the brake caliper is connected to flexible hydraulic lines, be careful not to pull too hard; simply rest it on the nearby front axle suspension. Next, grind the brake pads to create a chamfer on the edge that contacts the brake disc. When replacing both the brake pads and the brake disc at the same time, there is no need to grind the chamfer; they can be installed directly.

Which gear should be used to start an automatic transmission car?

To start an automatic transmission car, you need to shift to N gear first, then ignite, and then shift to D gear to start moving forward. Here are the detailed introductions of automatic transmission gears: 1. P gear is the parking gear: When the gear lever is in the P gear position, the transmission is in neutral inside, but the output shaft is mechanically locked. At this time, the car will stop in place even without stepping on the brake. It is generally used for long-term parking of the car. When shifting into P gear, the car must be completely stationary. Do not shift into P gear when the car is not fully stopped, and the handbrake must be engaged. When parking on a slope, you need to engage the handbrake first and then shift into P gear. 2. R gear is the reverse gear: When the gear lever is in the R gear position, the rotation direction of the transmission output shaft is opposite to that of the engine, allowing the car to move backward. When shifting into R gear, the car must be completely stationary. Do not shift into R gear when the car is not fully stopped. 3. N gear is the neutral gear: When the gear lever is in the N gear position, the gears inside the transmission are in idle state, and the clutch is not engaged. At this time, the load on the transmission is the smallest. N gear is generally used for short-term parking, such as waiting for a traffic light, and the transmission should also be in N gear when the car is being towed. 4. D gear is the driving gear: When the gear lever is in the D gear position, the gears inside the transmission automatically switch between the lowest gear and the highest gear according to the set shifting rules based on factors such as vehicle speed and throttle opening. In most cases, you can drive using D gear.
