When to Use the L Gear in an Automatic Transmission?

Where should ETC be installed on a vehicle?

The installation position of ETC for small cars is generally in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed in the upper part. The appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with built-in or later-added explosion-proof film, which may affect the signal transmission of the microwave communication link, it should be installed in the microwave sunroof strip. ETC is the abbreviation of Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the owner needs to provide the original and photocopy of the valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also needed. The vehicle must be under the name of an individual aged between 18 and 60. For units or companies, the organization code certificate (or business license) and official seal are required. Here are the precautions for installing ETC: Do not block the view. It is best to install it behind the rearview mirror: Many car models have a large inclination angle of the windshield, which reduces the driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spot. Installing it behind the rearview mirror on the right side can avoid blocking the view. Do not affect charging: The ETC electronic tag consumes power but generally does not need to be charged or have its battery replaced because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Once installed, do not remove it casually: The button in the middle of the adhesive is an anti-removal guide rod, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal guide rod in. If it is removed casually, the anti-removal guide rod will pop out and trigger the switch, locking the electronic tag and making 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 that: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, keep 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. If the speed is too fast, the vehicle device information cannot be read, leading to a failed deduction. When using a debit card bound to ETC, insufficient balance will also cause a failed deduction.

What problems can incorrect timing cause?

Problems caused by incorrect timing: premature ignition, delayed ignition, and erratic ignition timing. Premature ignition: The air-fuel mixture burns too early, which can easily cause knocking and disrupt normal combustion. When suddenly accelerating the engine, a metallic rattling sound may occur, potentially damaging engine components. There is also a slight knocking sound at idle. If the distributor housing is slightly rotated in the direction of the rotor, the sound may reduce or disappear, indicating premature ignition. When manually cranking the engine, there may be a reverse rotation (backfire) phenomenon. Using the starter becomes difficult, and the engine is hard to turn over. Delayed ignition: This reduces the gas pressure above the piston, leading to decreased power. The engine runs weakly, feels sluggish, and fails to increase speed when accelerating. High-speed operation becomes uneven. Severely delayed ignition can cause carburetor backfire, muffler explosions, increased engine temperature, higher fuel consumption, and difficulty starting the engine. Erratic ignition timing: The engine may experience shaking and knocking sounds, lack of power, carburetor backfire, exhaust pipe explosions, and may even fail to start or operate normally.

What Causes the Gear to Make Noise When Pressing the Brake in P Mode?

The noise heard when pressing the brake in P mode is caused by the protective device inside the transmission. When you press the brake in P mode, the sound is produced as the gear lever locking mechanism releases. Below is information about automatic transmission gears: Automatic transmission gears are divided into P, R, N, D, 2, and 1 or L: 1. P: Used for parking. It employs a mechanical device to lock the rotating parts of the car, preventing movement. When the car needs to remain stationary for an extended period or before leaving the vehicle after parking, the hand brake should be engaged, and the lever should be pushed into the "P" position. The P gear should only be used when the vehicle is completely stopped; otherwise, the mechanical parts of the automatic transmission may be damaged. 2. R: Reverse gear, used for backing up the vehicle. Typically, the safety button on the lever must be pressed to move the lever to the "R" position. The vehicle must be completely stopped before shifting to "R" gear; otherwise, the transmission may suffer severe damage. 3. N: Neutral gear. When the lever is placed in the "N" position, the power between the engine and the transmission is cut off. For short stops, the lever can be placed in this position while pulling the hand brake, allowing the right foot to rest away from the brake pedal. 4. D: Drive gear, used for normal road driving. Due to different designs across vehicle models, the "D" gear generally includes gears from 1 to high or 2 to high, automatically shifting based on speed and load. When the lever is placed in the "D" position, the driver can control the speed simply by adjusting the throttle pedal. 5. 2: Second gear is a forward gear, but the transmission can only switch between 1st and 2nd gears, not jumping to 3rd or 4th. When the lever is placed in the 2nd position, the car starts in 1st gear and automatically shifts to 2nd as speed increases. This gear is useful for ascending or descending slopes, as it keeps the vehicle steadily in 1st or 2nd gear. 6. 1: First gear is also a forward gear, but the transmission operates only in 1st gear without shifting to others. It is most effective in heavy traffic conditions or on steep slopes. When ascending or descending, it fully utilizes the engine's torque.

How many points are deducted for changing lanes by crossing a solid yellow line?

Changing lanes by crossing a solid yellow line results in a deduction of 3 points and a fine. Normally, crossing the line is actually a violation of the prohibition marking instructions. Penalty requirements: Changing lanes by crossing a solid line results in a deduction of 3 points. However, sometimes during manual review by traffic police, if it is seen that only a slight crossing did not affect other vehicles, no penalty will be imposed. If the violation is reviewed by the automated system, a violation record will appear because machines have no emotions. Methods to prevent crossing solid lines: Do not change lanes arbitrarily beyond the solid line before a traffic light intersection. If you fail to change back to the original lane in time, do not cross the line to return; instead, find an intersection to make a U-turn. When driving, clearly observe the markings on the ground, and only change lanes when the lines are dashed.

What Causes Tire Pressure Sensor Failure?

Tire pressure sensor failure may be caused by depleted battery in the sensor, signal transmission issues, or circuit malfunctions. Timely inspection and repair or replacement is necessary. After replacing the tire pressure sensor, activation and matching are required, which should be performed using specialized reset and matching equipment. Function of tire pressure sensors: They enable real-time automatic monitoring of various tire conditions. When the vehicle is in motion, sensors installed on each tire transmit data such as tire pressure and temperature via wireless signals to a central receiver. Upon receiving the data, the receiver analyzes and evaluates the tire pressure and temperature information, displaying alerts or warnings on the indicator as needed. Consequences of tire pressure sensor damage: If the tire pressure sensor fails or is damaged, it will be unable to monitor tire pressure. Some vehicles may display a tire pressure sensor failure alert, while others may show no tire pressure information on the dashboard. During driving, if the tire pressure sensor fails or is damaged and the tire experiences air leakage, the issue may not be detected promptly. Continuing to drive with insufficient tire pressure can adversely affect the tires and compromise the driving experience.
