Use the selection buttons on the steering wheel to display the odometer interface on the dashboard. Press and hold the "OK" button on the left control area of the steering wheel while simultaneously pressing the "Phone" button on the right side of the steering wheel. A menu will then appear. Start the vehicle or press the left button on the dashboard twice while the ignition is on, then turn off the engine. Hold the button without releasing it and start the engine.

As a long-time Mercedes-Benz owner, I often reset the maintenance light myself after servicing. The method is quite simple: Insert the key and turn it to the second position without starting the engine, so the dashboard lights up but the engine remains off. Then use the buttons or knobs on the steering wheel to navigate the menu options, where you'll typically find an icon labeled "Maintenance" or "ASSYST PLUS." Hold the OK button for about five seconds until you see the light blink a few times and turn off. Note that the procedure varies slightly between models like the C-Class or S-Class, and if your car uses the COMAND system, you'll need to confirm in a submenu. Resetting the maintenance reminder is meant to alert you for the next service, so only reset it after actual maintenance is done. I remember messing up the first time and nearly triggering a warning light, but checking the manual clarified the details. Now I can do it effortlessly every time, saving a trip to the dealership. The key is to stay patient and follow the steps carefully.

Just learned a neat trick from the repair shop about resetting the Mercedes maintenance light – quite interesting actually. The process isn't complicated: turn the key to ON position without starting the engine, use the center console or steering wheel controls to access the settings menu, select the maintenance option and hold the OK button. Older Mercedes models like vintage GLCs might require button combinations on the instrument panel for reset, while newer E-class models have much more intuitive interfaces. Always ensure the vehicle is stationary before operating as a safety precaution. If it fails, it could be button contact issues or system bugs – that's when you should let professionals handle it. After practicing a few times, I can now help friends with it quite effortlessly. Mastering this means timely vehicle maintenance while saving both money and time. When the light comes on during daily driving, don't panic – first consider the maintenance cycle before deciding whether to reset.

I figured out how to reset the maintenance light myself because I hate spending money at the dealership. The basic method: turn the key to the second position but don't start the engine, use the multifunction knob to find the maintenance menu on the dashboard and hold the confirm button for a few seconds. This process is super simple and takes just two minutes - Mercedes' design is very user-friendly. I recommend only resetting it right after maintenance, otherwise false alerts could compromise safety. For touchscreen-equipped smart versions, the operation is even more intuitive, just like using a smartphone. I think female owners can easily master this too - don't be intimidated by technical jargon, just try it and enjoy the sense of accomplishment. Remember safety first: always operate with the vehicle parked and don't rush.

What Causes a Car to Shake and Pull to One Side?

Car steering wheel shaking and pulling to one side are caused by inaccurate tire dynamic balance or deformation of the tire rim. Solutions: To address the pulling issue, inspect the lower control arm of the chassis and check for any gaps in the inner and outer ball joints of the steering gear. Replace them if gaps are found. Then, perform a four-wheel alignment, followed by tire dynamic balancing, and inspect the rims for any deformation. This will resolve the issue. It is recommended that car owners conduct regular inspections to ensure safe and reliable driving. Introduction to the Steering Wheel: The steering wheel is a wheel-shaped device used to control the direction of cars, ships, and airplanes. Its function is to convert the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft. It mainly consists of a frame, foam, and corresponding mounting clips or screw holes for the driver's airbag (DAB).

Can the VAT special invoice for cars be deducted?

VAT special invoices for cars can be deducted. Legal provisions: The "Measures for the Administration of VAT Collection at Retail Gas Stations" stipulate: when pre-sale units issue fuel cards or fuel vouchers, they should issue ordinary invoices. If the fuel purchasing unit requests a VAT special invoice, the pre-sale unit should issue a VAT special invoice to the fuel purchasing unit based on the records of the returned fuel cards or vouchers. The role of VAT special invoices: VAT special invoices serve as commercial vouchers. Since tax deduction is implemented based on the invoice, the purchaser must pay VAT to the seller. Therefore, the VAT special invoice also acts as a tax payment certificate, serving as legal proof of the purchaser's input tax amount.

Are the clutches of manual and automatic transmissions the same?

Manual transmission: mainly relies on the driver stepping on the clutch to complete the gear shifting operation. Automatic transmission: mainly relies on the hydraulic transmission principle of the torque converter to complete the gear shifting action. Definition of clutch: The clutch is located in the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. Requirements for clutch: The clutch is a common component in mechanical transmission, which can separate or engage the transmission system at any time. Its basic requirements include: smooth engagement, rapid and thorough separation; convenient adjustment and repair; small external dimensions; light weight; good wear resistance and sufficient heat dissipation capacity; easy and labor-saving operation. The commonly used types are jaw type and friction type.

Should the Valve Stem Be Replaced When Changing Tires?

As long as the valve stem cap doesn't fall off, it's fine. The valve stem cap is only to prevent foreign objects from entering that small space; there's no need to tighten it excessively, as this can easily damage the screw. Valve Core: The "valve core," also known as the "airtight core," is primarily used for tire inflation and preventing air leakage. The main body of the "valve core" is a small column with a hollow upper end and a solid lower end, with a small hole on the side of the lower end connecting to the hollow part. Valve cores are mainly categorized into: English-style valve pins, American-style valve cores, French-style valve cores, as well as German-style valve pins and Italian-style valve cores. Automobile Tires: Automobile tires are one of the important components of a vehicle. They come into direct contact with the road surface and, together with the vehicle's suspension, help to absorb shocks during driving, ensuring good ride comfort and smooth driving.

Why does the air in the small air pump storage tank disappear quickly?

The reasons why the air pump does not inflate include the softening of the built-in spring plate preventing it from rebounding and pipeline blockage. Below is a detailed explanation of the causes and solutions to this problem: Softening of the built-in spring plate: The spring plate inside the air pump will gradually soften with use. When the pressure in the air storage tank reaches 4 atmospheres, the softened spring plate cannot rebound due to the back pressure from the storage tank, making it impossible to continue inflation. In this case, a new spring plate needs to be replaced. Pipeline blockage: If the air outlet pipeline of the air pump is blocked, the air pump will be in a state of high internal pressure and unable to inflate. The solution is to remove the pipeline and replace it with a new one.

What Are the Techniques for Right-Angle Turns on Narrow Roads?

Techniques for right-angle turns on narrow roads are as follows: When preparing to make a right turn ahead, it's best to position the vehicle about 20 centimeters closer to the left side in advance to avoid obstacles on the right side of the car. When the rearview mirror aligns with the right corner, turn the steering wheel fully to the right. If the road width ahead allows, you can delay turning the wheel fully to the right, enabling the turn to be completed in one smooth motion. If the road ahead is not wide enough, you may need to make multiple adjustments to the steering wheel, positioning the vehicle as close as possible to the side farther from the corner to gain a larger turning angle. While continuing the turn, use the right rearview mirror to monitor the distance between the right side of the vehicle and the corner, paying attention to obstacles ahead as the front of the car arcs to the right. Maintain a slow speed and yield to pedestrians while driving. Ensure that neither the front of the car nor the right side will come into contact with pedestrians or obstacles before proceeding with the turn. Avoid forcing the turn. Timing for steering wheel movements during right-angle turns on narrow roads: Before turning, try to drive as close to the outer side as possible. When the front of the car is about 50-70 centimeters from the opposite edge, start turning inward. Keep an eye on the front while also checking the rearview mirror. When you feel the middle of the car is about to pass the vertex of the right angle, gradually straighten the wheel. When entering the right angle, position the right (left) side of the front of the car at the one-third point opposite the turning direction. At this point, the right (left) wheels should be about 30 centimeters from the edge. During the turn, when the small triangular window pillar of the right (left) front door aligns with the protruding point of the right angle, quickly turn the steering wheel fully to the left. As you exit the corner, swiftly straighten the wheel once aligned with the exit and continue driving forward until completely out of the right angle.
