Automatic transmission's forward gear is labeled as D because D stands for Drive. Drive means to operate or control the movement of a vehicle. The D gear in an automatic transmission is also known as the forward gear or drive gear, and it is the most commonly used gear. When the vehicle needs to move forward, the driver can shift to D gear, which drives the vehicle forward. When the vehicle is in D gear, it can automatically adjust the matching gear based on engine speed and load, keeping the vehicle within the appropriate speed range. In addition to the D gear, other gears in the transmission include: P gear (Parking gear), which should be engaged after parking to prevent the vehicle from rolling; R gear (Reverse gear), which can only be engaged when the vehicle is completely stopped; S gear (Sport gear), which allows the automatic transmission to mimic manual control, providing the vehicle with greater power and a more dynamic driving experience; and L gear (Low gear), which is generally used when going downhill.

What Does Shallow Charging and Discharging Mean?

Shallow charging and discharging refers to not charging or discharging the battery to its full capacity, meaning not charging to 100% and not discharging completely. Below is a brief introduction to shallow charging and discharging: When the battery is charged only when it falls below 10% or is completely drained, it is considered over-discharging. When the battery is charged between 20% and 90% and not fully charged to 100%, it is considered shallow charging and discharging. Shallow charging and discharging means not reaching the battery's maximum capacity during charging and discharging, i.e., not charging fully and not discharging completely. Precautions: Do not charge the battery after it is completely drained, as this can affect the battery's lifespan. Avoid using the phone for extended periods while charging; wait until charging is complete before operating the device. Avoid Over-Discharging: Charge the device when it prompts "low battery." If you wait until the device shuts down automatically, the battery has already been over-discharged, which can impact its lifespan. Avoid Over-Charging: When the charger indicates that the battery is fully charged, unplug the charger. Modern chargers usually have an auto-stop feature when fully charged. While leaving the battery connected to the charger for a short time is not a problem, keeping it connected for extended periods can lead to over-charging. This happens because, late at night, when grid voltage rises, the charger may resume charging even after it had stopped, causing over-charging, which can also affect battery lifespan.

Is the original driver's license still valid if I find it after getting a replacement?

The original driver's license cannot be used after obtaining a replacement. If the original driver's license was lost and a replacement was issued, the driver must surrender the original license to the vehicle management office or destroy it themselves. It is not permitted to use both licenses simultaneously. Currently, each driver's license has a unique identification number and is managed through a computer tracking system. Once a replacement license is issued, the original license and its number will be marked as invalid in the driver's license management system. Process for replacing a driver's license: Prepare the original ID card, a copy of the ID card, and a one-inch white-background photo; visit the service hall of the vehicle management office to apply for a replacement, receive and fill out the "Motor Vehicle Driver's License Application Form"; submit the original ID card, copy, one-inch white-background photo, and the application form to the staff; after the materials are reviewed by the staff, proceed to the corresponding manual window to pay the fee; in most cases, the new driver's license can be issued on the spot. If it is not issued immediately, the replacement license will be issued within three days as per regulations. Precautions after replacing the driver's license: Once the replacement process is completed, the original license cannot be used to drive a motor vehicle before receiving the new one; if the replacement application is accepted but the new license is not issued on the same day due to time constraints, driving during this "gap period" before receiving the new license is prohibited and will be considered as driving without a license.

What is the reason for the Subaru central lock not responding?

Subaru central lock cannot be opened due to poor contact points or wiring issues in the central lock system. Poor Contact: There may be oil stains, debris, or foreign objects on the contacts; prolonged use may cause surface oxidation; arc erosion can lead to defects, burrs, or the formation of metal particles; or there may be jamming in the moving parts. Solutions include: For oil stains, debris, or foreign objects on the contacts, wiping with a cotton cloth soaked in alcohol or gasoline can help. If the contacts are made of silver or silver-based alloys, the formation of an oxide layer or minor burns and blackening due to arcing generally does not affect functionality and can be cleaned with alcohol, gasoline, or carbon tetrachloride solution. Wiring Issues: Poor contact at the connection points between the busbar and other equipment can interrupt circuit operation. A fault in a section of a circuit during electrical equipment operation can cause a line break, blocking current flow and leading to abnormal conditions in related components of the electromechanical equipment. Any wiring issue can have a certain impact on the entire electromechanical working system. Solutions: If using the remote to unlock the door, the remote battery may be dead, or there may be strong signal interference nearby. The remote key usually contains a hidden mechanical key, which can be used instead. If the mechanical key cannot open the car door, the central lock system may be in an electronic lock state, or the door lock cylinder may be stuck due to prolonged use and cannot be turned. The first situation requires waiting one or two hours for the lock to release before attempting to unlock again. The second situation may require forceful measures, such as breaking the window to open the door, or contacting a 4S shop for repairs.

What Causes the Fault Light to Illuminate in a Haval H6?

The reasons for the fault light illuminating in a Haval H6 include poor-quality or substandard gasoline, oxygen sensor malfunction, excessive spark plug carbon buildup, and engine knocking. Regardless of the cause triggering the engine fault light, it is necessary to use a computer diagnostic tool for diagnosis. If it is a false fault code, simply clear it. If there is a genuine fault, troubleshooting and repairs should be conducted based on the fault code, such as cleaning spark plug carbon deposits, replacing the oxygen sensor, or changing the gasoline. Often, shortly after refueling, the engine fault light on the car's dashboard illuminates. This is usually due to filling up with poor-quality gasoline at non-standard gas stations, leading to incomplete combustion of the air-fuel mixture during engine operation and triggering the fault light. While this does not affect driving safety, it can cause some degree of harm to the engine. The front oxygen sensor's role is to detect the air-fuel ratio under different engine operating conditions, with the ECU computer using this signal to adjust fuel injection and calculate ignition timing. If the oxygen sensor is damaged or its connector is damaged or loose, it can cause the air-fuel mixture to become too lean or too rich, leading to the fault light illuminating. Spark plug carbon buildup can result in poor engine performance, manifesting as difficulty starting, unstable idling, poor acceleration, backfiring during rapid acceleration, excessive exhaust emissions, and increased fuel consumption. Engine knocking can cause the car to lack power during driving, produce excessive engine noise, and in severe cases, be accompanied by a knocking sound from the cylinders.

What is the difference between dealership invoice and auto trade invoice?

Dealership invoice refers to the purchase invoice from a 4S store, while auto trade invoice refers to the purchase invoice from an auto trade company. The differences between the two lie in the after-sales service and price of the vehicle. Generally, buying a car from a 4S store is more expensive than from an auto trade company. This is because auto trade companies source vehicles from 4S stores with the lowest prices nationwide, whereas 4S stores source directly from manufacturers. Additionally, the operational costs of 4S stores are higher than those of auto trade companies, resulting in different prices on the invoices. Using an auto trade invoice might affect the vehicle's future after-sales service. Some vehicles purchased from auto trade companies may only receive after-sales service at local 4S stores, which may not be recognized by 4S stores in other regions. However, with a 4S store invoice, after-sales service can be obtained at any 4S store nationwide. How to distinguish between a genuine auto trade invoice and a 4S store invoice: Check the watermark: Genuine invoices are printed on special anti-counterfeiting paper with black and white watermarks, and the watermark pattern has a noticeable texture when touched. Fake watermarks have a weaker texture and appear blurry. Prize area difference: The covering layer in the prize area of a genuine invoice is made of laser gold-stamped film, presenting a matte finish, while most fake invoices have inferior covering layer technology in the prize area. Color difference: Genuine invoices have a deeper color, appearing pinkish, while fake invoices have a much lighter color, looking somewhat pale.
