The tire pressure warning light may come on due to insufficient tire pressure or damage. You should immediately get out of the car to check whether the tires are normal or have been punctured, causing air leakage. The tire pressure warning light is used to display the tire pressure status of the vehicle's tires. Under normal circumstances, this indicator light should be off. Tire pressure refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and engine damage will lead to the end of the car's life. Tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the car's performance and power. Nowadays, many tires are not filled with air, and for these tires, the tire pressure requirements are relatively strict. For tires filled with air, the pressure is related to seasonal changes and is closely linked to the car's performance, such as comfort and load capacity, and can also affect the lifespan of the tires.

When the tire pressure warning light comes on, I know there's an issue with the tires—it could be low pressure or too high. More commonly, it's low pressure, like from a nail puncture causing a leak or natural pressure drop due to colder weather. You should immediately find a safe place to stop and check each tire for obvious deflation or damage. If you find any, it's likely a leak, and it's best not to drive further—head to a repair shop for a patch. If nothing's visible, use a simple tire pressure gauge to measure the pressure. There's a label on the car indicating the standard pressure; try inflating to that level. Drive for a while, and if the light goes off, you're fine. If it stays on, the sensor might be faulty or there could be a slow leak. Don't underestimate this—driving with incorrect tire pressure increases fuel consumption, accelerates tire wear, and raises the risk of a blowout at high speeds. I make it a habit to check tire pressure monthly, keeping it at the optimal level to avoid trouble.

Are Chery Engines the Same as BMW Engines?

Chery engines and BMW engines are the same. Introduction to Engines: An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. The term 'engine' can refer to both the power generation device and the entire machine including the power unit. How to Identify Engine Models: Engine models are usually marked on the valve cover. Of course, the specific markings vary depending on the model. The first digit indicates the number of cylinders, followed by digits representing the bore diameter. Letters have three meanings: cylinder arrangement (no symbol means in-line, 'V' means V-type, 'P' means flat), cooling and turbocharging (no symbol means water-cooled, 'F' means air-cooled, 'N' means condensation-cooled, 'Z' means turbocharged), and usage codes ('T' for tractors, 'M' for motorcycles, 'G' for construction machinery, 'Q' for vehicles, 'D' for generator sets).

What Causes the Rear Axle Noise in BMW 5 Series?

BMW 5 Series rear axle noise causes are as follows: Noise due to improper gear backlash: Under normal conditions of main reducer bearing preload, metallic impact sounds occur at the rear axle during initial vehicle movement or gear shifting for a short period. When the vehicle speed stabilizes, the impact sound turns into continuous noise. During sudden throttle changes, irregular "clicking" or "clunking" sounds appear at the rear axle - this generally indicates excessive gear backlash. If there's a siren-like "howling" sound during low-speed driving, accompanied by "clanging" noises during acceleration or deceleration and rear axle overheating, this usually indicates insufficient gear backlash. These abnormal sounds are typically caused by severe gear and spline wear, excessive or insufficient gear backlash, or insufficient lubrication. Noise due to uneven gear backlash: When starting or during rapid speed changes, rhythmic "grinding" sounds occur, accompanied by body rear-end vibrations during turns - these are usually caused by uneven gear backlash. Loose differential housing screws, loose ring gear rivets (or screws in some vehicles), causing gear wobbling and jumping during operation which leads to inconsistent gear backlash, are the direct causes of uneven backlash.

How Much Coolant Should Be Added to a Mercedes-Benz C-Class?

Mercedes-Benz C-Class requires 4 to 4.5L of coolant. It's recommended to prepare 6L and store the excess for top-ups when coolant levels drop. Coolant is a special additive-containing liquid primarily used in liquid-cooled engine cooling systems. It provides excellent performance in winter antifreeze protection, summer anti-boil, year-round anti-scale, and corrosion prevention. How to replace coolant: Before a complete coolant replacement, conduct a thorough inspection for leaks or cracks in all pipes, with particular attention to the five-way hose. Coolant flows through this hose before being distributed to different parts of the vehicle. If leaks are found in this area, replace the hose or resecure connections as needed. Drain the old coolant, then flush the channels with clean water. Add water to the coolant reservoir and let it circulate continuously through the engine cooling system. Idle the engine for 3-5 minutes to circulate the water. Initially, the discharged water may appear slightly pinkish. Continue flushing until the water runs clear. Remember to remove the heater hose and drain the heater core completely. About one hour after draining, add new coolant through the radiator hose. Then pour another container of coolant into the reservoir until nearly full. Run the engine for about 10 minutes - as air escapes from the system, the coolant level will drop. Top up to the "MAXT" mark on the reservoir.

Does the vehicle body touching the line result in point deduction in Subject 2 reverse parking?

Touching the line during reverse parking results in a 100-point deduction, making the test unsuccessful. Other actions that lead to a 100-point deduction include the vehicle body crossing the line, failing to park properly, stopping midway, not following the prescribed route or sequence, and exceeding the time limit. The total score for both subjects is 100 points, with evaluation criteria set for failure, 20-point deduction, 10-point deduction, and 5-point deduction. The rules for the Subject 2 driving test state that stopping midway, rolling back, or not following voice prompts result in failure. Wheel or body touching the line also leads to test failure. Many learners encounter the issue of touching the line during Subject 2 training, with "touching the line" being the most common reason for failure. The main cause of this issue is learners not mastering the correct timing for steering. Besides missing the right moment to steer, another reason could be the steering speed not matching the vehicle's speed. Subject 2 point deduction standards: Not wearing a seatbelt: 100-point deduction. Starting the engine without the gear in neutral: 100-point deduction. Not using turn signals (including starting, lane changing, overtaking, turning, and parking); using turn signals for less than three seconds (this is easily overlooked!); forgetting to turn off turn signals or incorrect use: 10-point deduction. Stalling once: 10-point deduction. Reverse parking: Not following the prescribed route sequence: 100-point deduction. Vehicle body crossing the line: 100-point deduction. Failing to park properly: 100-point deduction. Before reversing, not having both front wheels pass the control line: 100-point deduction. Exceeding 210 seconds to complete the task: 100-point deduction. Stopping for more than 2 seconds midway: 5-point deduction each time. Slope parking and starting: After stopping, if the front bumper is not aligned with the pole line and exceeds 50 cm front or back: 100-point deduction. After stopping, if the front bumper is not aligned with the pole line but does not exceed 50 cm front or back: 10-point deduction. After stopping, exceeding 30 seconds to start: 100-point deduction. Wheels touching the road edge line while driving: 100-point deduction. Rolling back more than 30 cm when starting: 100-point deduction. After stopping, if the vehicle body is more than 50 cm from the road edge line: 100-point deduction. Not tightening the parking brake after stopping: 10-point deduction each time. After stopping, if the vehicle body is more than 30 cm but not exceeding 50 cm from the road edge line: 10-point deduction each time. Rolling back more than 10 cm but less than 30 cm when starting: 5-point deduction each time. Parallel parking: After parking, if the vehicle body crosses the line: 100-point deduction. Not using or incorrectly using turn signals when parking: 10-point deduction. Exceeding 90 seconds to complete the task: 100-point deduction. Touching the parking space edge line with the vehicle body while driving: 10-point deduction each time. Wheels touching the lane edge line while driving: 10-point deduction each time. Stopping for more than 2 seconds midway: 5-point deduction each time. Right-angle turning: Wheels touching the road edge line: 100-point deduction. Not using or incorrectly using turn signals when turning, or not turning off turn signals after turning: 10-point deduction. Stopping for more than 2 seconds midway: 5-point deduction each time. Curve driving: Wheels touching the road edge line: 100-point deduction. Stopping for more than 2 seconds midway: 100-point deduction. Not driving in second gear or higher: 5-point deduction.

What does ETC on highways mean?

Highway ETC (Electronic Toll Collection) translates to electronic toll collection, which is a non-stop toll collection system. On highways, there will be one or more ETC lanes. The ETC toll collection method: Through dedicated short-range microwave communication between the on-board RFID tag installed on the vehicle's windshield and the microwave antenna on the ETC lane at the toll station, using software networking technology to conduct background settlement processing with the bank, thereby achieving the purpose of vehicles passing through bridge toll stations without stopping to pay tolls. Banks install this type of ETC express card with a post-payment system. ETC application conditions are as follows: Provide the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate. The photocopy of the driver's license should include the page with the most recent annual inspection stamp; Postal credit card application form. This credit card is used to bind the ETC card. After obtaining the credit card, swipe it twice and use the POS slip to collect the ETC on-board device for free at the designated postal outlet. No fees are charged during this process; Be between 18 and 60 years old; Own a vehicle under personal name. Below are precautions for installing ETC: Do not obstruct the view. It is best to install it behind the rearview mirror: Many car models have a large inclination angle of the windshield, resulting in a smaller driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spots. Install it behind the rearview mirror on the right side to avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power, but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and do not install it in a position where the solar panel can be easily blocked. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal lever in. If it is removed arbitrarily, the anti-removal lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. When using ETC, note: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front; The speed limit for ETC lane recognition is 20 kilometers per hour. Driving too fast may result in failure to read the vehicle's device information and failed toll deduction; When using a debit card to bind ETC, insufficient balance may also cause toll deduction failure.
