When the Mercedes-Benz Run-Flat Indicator stops working, it indicates that the pressure in at least one tire deviates from the pressure recorded during the last reset. It is necessary to check the tire pressure and perform a reset. If the tire pressure is insufficient, the dashboard will reactivate the Run-Flat Indicator. The vehicle owner should first check the pressure in all four tires. If the indicator persists after adjustments, the tire pressure needs to be restored and reset. If one or more tires have low pressure, first identify which tire(s) are affected. The recommended pressure is 2.4 bar for the front tires and 2.6 bar for the rear tires. After addressing any leaks, turn the ignition to position 2. Use the buttons on the steering wheel to access the maintenance menu on the dashboard, select 'Tire Pressure Normal,' and confirm to stop the warning. Reset method: Turn the key to position 2, use the left menu button on the steering wheel to display the odometer interface on the dashboard, then press the up button on the left side of the steering wheel; The dashboard will display 'Run-Flat Indicator Reactivated,' press the R button on the dashboard; The dashboard will show whether the tire pressure is normal; Press the plus button on the right side of the steering wheel, wait for 10 seconds, then turn off the key and restart the vehicle.

What is the working principle of BYD's DM-i Super Hybrid?

DM-i Super Hybrid is based on a high-capacity battery and a high-power motor, with the vehicle being driven by the high-power motor during operation. The core component of BYD's DM-i Super Hybrid technology is the newly developed Xiaoyun plug-in hybrid-specific engine by BYD, which comes in two different versions—the 1.5L engine is mainly used in the Qin PLUS and Song PLUS, while the 1.5T turbocharged engine is used in the larger Tang DM-i model. The DM-i Super Hybrid is introduced as follows: 1. DM-i Super Hybrid models also include two key components: the EHS dual motor and the DM-i Super Hybrid-specific Blade Battery, along with a series of vehicle control systems, engine control systems, motor control systems, and battery management systems, collectively forming the Super Hybrid system. Most importantly, these core components and key technologies are entirely independently developed by BYD. 2. Power: The high-capacity, high-power battery can also support the efficient power system, keeping it operating in the high-efficiency zone for extended periods. Speaking of the world's most efficient power system equipped in the DM-i Super Hybrid, it features the Xiaoyun plug-in hybrid-specific 1.5L high-efficiency engine with a thermal efficiency of 43.04%, and the Xiaoyun plug-in hybrid-specific turbocharged 1.5Ti high-efficiency engine with a thermal efficiency of up to 40%.

What maintenance items are included for the Mercedes-Benz B7?

Mercedes-Benz maintenance B7 item indicates that the current maintenance is due, and specific maintenance items need to be checked at the 4S dealership based on the mileage. Below are the relevant introductions to the maintenance items: 1. Oil filter: The replacement of engine oil and oil filter is primarily for the maintenance of the lubrication system. The main function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's function is to remove various impurities from the engine oil to ensure the normal operation of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, the car should be serviced every 5000KM. 2. Air filter: The air filter's role is to filter the air before it enters the cylinder, removing impurities, dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The gasoline filter is generally replaced after driving 20,000-25,000KM.

What is the fuel tank capacity of the 2021 Audi A6?

2021 Audi A6 has a fuel tank capacity of 73 liters, and the gasoline specification is 95 octane or higher unleaded gasoline. The Honda CR-V is a mid-to-large-sized car under FAW-Volkswagen Audi. The 2018 Audi A6 has a fuel tank capacity of 75 liters, while the 2019 and 2020 Audi A6 models have a fuel tank capacity of 73 liters, with the gasoline specification being 95 octane or higher unleaded gasoline. If the owner wants to check the remaining fuel level, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it indicates that the fuel is almost empty, and when it is near F, it means the fuel level is sufficient. The maintenance of the fuel tank is as follows: Drain accumulated water and sediment from the fuel tank, and check for any fuel leakage at the fuel pipe joints and switches. For fuel tank caps equipped with air valves and vapor valves, also check if the vent holes are clear. The filter screen at the fuel filler neck should be kept intact to prevent impurities from entering the fuel tank during refueling and clogging the fuel lines. The sealing gasket of the fuel filler cap should also be intact to prevent fuel from spilling out while driving.

How to Determine if a Car is Pulling to One Side?

When driving on a flat road, take both hands off the steering wheel and drive straight for 100 meters. If the car does not drive in a straight line, it is pulling to one side. The reasons for a car pulling to one side are as follows: 1. Uneven load distribution: This mainly refers to whether the trunk has been carrying heavy items concentrated on one side. If so, moving them to the center can help. 2. Uneven tire pressure on both sides: The solution is to inflate both tires to the standard pressure. Additionally, check if the wear on both wheels is uneven, causing differences in wheel diameter and traction. 3. Damaged springs and shock absorbers: Focus on inspecting the lower side to see if the spring is overly compressed due to insufficient elasticity or if the shock absorber is leaking oil. If there are indeed issues, repair or replace them as needed. When replacing springs, always change both sides together; otherwise, it will create a new imbalance.

What is the fuel tank capacity of the 2013 Buick GL8 in liters?

2013 Buick GL8 has a fuel tank capacity of 77 liters, using 92-octane or higher unleaded gasoline. It is an MPV model under SAIC-GM Buick. Among similar models, the Honda Odyssey has a 50-liter fuel tank capacity, while the Trumpchi M8 has a 65-liter fuel tank. To check the remaining fuel level, owners can observe the fuel gauge on the right side of the dashboard, marked with E and F. When the needle approaches E, it indicates low fuel, while nearing F means sufficient fuel. Fuel tank maintenance includes: Draining accumulated water and sediment from the tank, and checking for oil leaks at pipe joints and switches. For fuel tank caps equipped with air and vapor valves, ensure the vent holes are unobstructed. The filler inlet filter should remain intact to prevent impurities from entering the tank during refueling and clogging the fuel lines. The sealing gasket on the fuel filler cap should also be intact to prevent fuel spillage while driving.

What is Oil Burning?

Oil burning refers to the situation where engine oil enters the combustion chamber of the engine and participates in combustion along with the air-fuel mixture. Here are the relevant details: 1. Consequences of oil burning: If a vehicle exhibits oil burning, it can lead to rapid damage of the oxygen sensor, increased carbon deposits in the combustion chamber, unstable idling, reduced acceleration power, increased fuel consumption, excessive exhaust emissions, and other adverse effects. 2. Factors causing oil burning: Aging and failure of the valve stem seals can allow oil to enter the combustion chamber through the gap between the valve stem and the guide hole under the influence of intake manifold vacuum, resulting in combustion.
