The average fuel consumption of the Mercedes ML400 is 12.25L/100km. Improper driving habits: Fuel consumption is closely related to the driver's personal habits, such as idling for long periods without turning off the engine or frequent ignition, aggressive acceleration or frequent braking while driving, driving at high speeds in low gears or low speeds in high gears, etc. These driving habits significantly impact fuel consumption. Fuel quality and carbon deposits: Many drivers do not pay attention to fuel quality. Poor-quality gasoline can increase carbon deposits, which roughens the intake pipe walls, affects the intake effect and mixture quality, leading to a sharp rise in fuel consumption.

I drove a Mercedes-Benz ML400 for two full years, and honestly, the actual fuel consumption was quite painful. In city driving with frequent traffic jams, the fuel consumption could reach 13 to 15 liters per 100 kilometers, sometimes even approaching 16 liters in severe congestion. On the highway, it was more economical, dropping to around 10 to 11 liters. I usually drive steadily, avoiding sudden acceleration or braking, and I regularly check tire pressure and change the engine oil, which helps save a bit on fuel costs. Overall, driving this SUV requires budgeting for higher fuel expenses due to its weight and aerodynamic drag. Using air conditioning or driving fully loaded increases fuel consumption further, with monthly fuel costs estimated at over 1,000 yuan. I recommend considering daily road conditions before purchasing this vehicle—using it in suburban areas or on highways would be more cost-effective.

Can a Car Battery Be Jump-Started in the Rain?

Yes, a car battery can be jump-started in the rain, but the connectors must not be exposed to rainwater. Here are the relevant details: Connection: When charging in the rain, first connect the vehicle-side components before connecting to the charging station. This prevents electric leakage, as the plugs and sockets on the vehicle side will establish a live connection safely, avoiding electric shock. Parking: When parking, try to choose a higher ground position. Staying in low-lying areas for extended periods may cause the battery or charging port to become submerged in water. Check the Plug: Inspect the plug to ensure there is no accumulated water or debris, guaranteeing proper contact for normal charging. Cover: After charging is complete, promptly cover the charging port tightly when removing the plug to prevent water ingress.

What to Do When Your 5-Year Driver's License Expires?

If your driver's license has been valid for 5 years, you don't need to renew it yet. The annual review system has been abolished, and the renewal period is now every 6 years. If your driver's license has been expired for more than one year but less than two years without renewal, you can restore its normal use by passing the subject one exam. However, if it has been expired for more than two years, you will need to reapply for a new license. A driver's license, also known as a 'driving license,' is an official document issued by the government's transportation department to individuals who qualify to drive, typically in the form of a card. To obtain a driver's license, you must meet the minimum age requirement and pass a driving test. The license usually specifies the types of motor vehicles the holder is permitted to drive, such as motorcycles, cars, trucks, buses, etc.

What Causes the Yellow Engine Light in a Porsche Cayenne?

The yellow engine light in a Porsche Cayenne indicates a fault in the engine. Generally, when a warning light illuminates on the instrument panel, it signifies an abnormality in the corresponding component. Below are the relevant explanations: 1. Damaged Engine Oxygen Sensor: There are many reasons why the engine warning light may illuminate, one of which could be a damaged oxygen sensor. The vehicle's onboard computer uses the oxygen sensor to monitor the oxygen concentration in the exhaust gases. Based on the information transmitted by the sensor, it controls the engine's fuel injection quantity and adjusts the air-fuel ratio. If the oxygen sensor is damaged, the onboard computer cannot receive the transmitted information, causing the engine warning light to illuminate. 2. Damaged Air Flow Sensor: Another possible cause is a damaged air flow sensor. If the air flow sensor is damaged, the onboard computer cannot detect the intake air volume information, which will naturally cause the engine warning light to illuminate and also affect the engine's normal operation.

What does the pre-test for Subject 2 mean?

Subject 2 pre-test refers to the mock test at the examination site. Here are the precautions for Subject 2 test: Reversing into the garage: The main points for deduction include pressing the line while reversing, the car not entering the garage, exceeding the time limit, and not following the prescribed route. Reversing into the garage must be completed within 210 seconds, exceeding the time limit will result in disqualification, not following the sequence will also result in disqualification, and pay attention to the 30cm margin issue while reversing. Parallel parking: The main points for deduction in parallel parking include the turn signal, 30cm margin, and pressing the line. Right-angle turn: The main points for deduction in the right-angle turn are the turn signal and pressing the line. Operating the turn signal incorrectly after entering the test area will result in a 10-point deduction.

What Causes the Abnormal Noise in Automatic Transmission?

Here are the specific reasons for abnormal noise in automatic transmission: Bearing wear and damage: When bearings wear out, the gap increases and the fit precision decreases; when bearings are damaged, they cannot operate normally, resulting in abnormal sounds and even causing damage to transmission components, leading to further malfunctions. Long-term failure to replace transmission fluid: The transmission fluid becomes thick and loses its fluidity, which means there is no protective layer between components, leading to direct friction that exacerbates mechanical wear and causes abnormal noise. Using inferior transmission fluid: Inferior transmission fluid has poor heat resistance and is prone to oxidation, forming sludge and residue that can clog filters and oil passages, increasing friction between internal components of the automatic transmission and causing abnormal noise in the vehicle.

How many points are deducted for speeding by 15%?

Speeding by 15% results in a deduction of 3 points. The introduction to speeding penalties is as follows: Penalty regulations: Speeding within 10% of the road speed limit results in a warning without point deduction, speeding between 10%—20% results in a 3-point deduction, speeding between 20%—50% results in a 6-point deduction, and speeding over 50% results in a 12-point deduction. The formula for calculating the percentage of speeding: (Speed/Limit speed—1)×100, which calculates the percentage of speeding. For example, if the speed limit is 70km/h and the vehicle speed is 80km/h, divide 80 by 70, subtract 1, and multiply by 100 to get 14.28, meaning the speeding is 14%. If the speed limit is 60km/h and the vehicle speed is 70km/h, then divide 70 by 60, subtract 1, and multiply by 100, resulting in 16% speeding.
