What to Do If You Didn't Swipe Your ETC Card When Exiting the Highway?

If you didn't swipe your ETC card when exiting the highway, you can contact the bank, the toll station and highway company, or call the highway service hotline. Below are two situations regarding not swiping the ETC card when exiting the highway: 1. Not swiping the card: If the vehicle entered the highway via ETC but didn't swipe the card when exiting, the next time the vehicle enters the highway, the entry point will be the same as the previous exit point. If it's within the free time period, no charge will be applied. If it's within the charging time period, the fee will be calculated based on the distance from the point where the ETC card was swiped at the highway entry to the current entry point. 2. Unsuccessful swipe: If the ETC vehicle fails to swipe the card successfully when exiting the toll station but has already exited, meaning the ETC card wasn't successfully swiped, the vehicle won't be able to enter the highway via the ETC lane next time. This situation is easy to handle—just give the ETC card to the toll station staff to swipe it.

How to Check for Clutch Failure?

Here are the methods to check for clutch failure: 1. Check if the driven plate can be turned easily. Remove the clutch bottom cover, shift the transmission into neutral, fully depress the clutch pedal, and then use a screwdriver to turn the driven plate. If it turns easily, the clutch disengages properly; if it doesn't turn, the clutch is not fully disengaged. 2. Check if the clutch pedal free play is too large and adjust it. 3. Check if the release lever heights are consistent and not too low. Under the vehicle, move the release fork so that the front end of the release bearing lightly touches the inner end of the release lever. Rotate the clutch one full turn to inspect. If the inner ends of the release levers do not simultaneously contact the release bearing, the release lever heights are inconsistent and should be adjusted. If the release lever heights are consistent but the clutch still doesn't fully disengage, check the lever height. Adjust all release levers to the same height. If the clutch then fully disengages, it indicates improper previous adjustment or excessive wear. After adjusting the release levers, the clutch pedal free play must be readjusted. 4. If the clutch still doesn't fully disengage after the above adjustments, remove the clutch and check if the driven plate is installed backward, if axial movement is difficult, if the main and driven plates are warped, if the release lever screws are loose, or if the floating pins are missing. 5. For clutches with newly riveted friction plates, check if the driven plate and friction plates are too thick. If they are, add shims between the clutch cover and flywheel. 6. For hydraulically operated clutches, in addition to the above checks, also check if the brake fluid is low, if there are any leaks in the pipes, and bleed the air from the hydraulic system.

Is It a Problem If the Car's Undercarriage Gets Scraped?

You need to inspect the undercarriage. As long as there are no fluid leaks or deformation of mechanical parts, it should be fine. Generally, when cars leave the factory, the undercarriage undergoes protective treatments that can withstand certain impacts and handle minor scrapes and bumps without issues. If the scraping occurred at a low speed and the sound wasn't too loud, the problem is likely minor. Here are the benefits of undercoating: 1. Corrosion Protection: Rust on cars often starts at the underbody. Every time you wash the car, residual water can accumulate underneath, leading to potential corrosion over time. Undercoating forms a protective layer that prevents damage from acid rain, road salts, or alkaline wash water. 2. Stone Chip Protection: While driving, small stones can be kicked up by the tires. The impact force of these stones is proportional to your speed—for example, a 10-gram stone at 80 km/h can have an impact force 100 times its weight, enough to breach a 30-micron paint layer. Undercoating prevents such breaches, stopping rust from forming. 3. Vibration Damping: The engine and wheels are mounted on the undercarriage, and their vibrations can resonate with the chassis at certain frequencies, causing discomfort. Undercoating helps reduce this resonance. 4. Thermal Insulation: In winter, when the car's heater is on, warm air tends to sink, while cold air from the ground rises. Most of this heat exchange happens at the floor of the vehicle. Effective undercoating, with its quartz sand layer, isolates these temperature differences, improving energy efficiency. 5. Noise Reduction: On highways, tire noise increases with speed. A well-protected undercarriage significantly reduces interior noise. 6. Impact Protection: Undercoating materials can be 1.5 to 2.5 mm thick, providing a buffer against road protrusions that might otherwise damage the undercarriage.

How to Shift from First Gear to Second Gear in a Car?

To shift from first gear to second gear in a car, the method is as follows: After a smooth start, lightly press the accelerator, then release the accelerator and depress the clutch. Shift into second gear, gently release the clutch, and lightly press the accelerator again. Generally, when starting a motor vehicle, it is necessary to use first gear, or when climbing a steep slope. After a normal start and reaching a speed of 5 to 10 kilometers per hour or more, you can shift into second gear during the gap between pressing and releasing the accelerator. A manual transmission (MT), also known as a manual gearbox, requires the driver to manually move the gear lever to change the gear meshing device inside the transmission, altering the gear ratio to achieve speed changes. An automatic transmission typically refers to a car's automatic gear-shifting mechanism, where the control system of the automatic transmission selects the appropriate gear based on the engine's speed and load while driving.

What Are the Impacts of a Locked Driver's License?

A locked driver's license prohibits the holder from driving on the road. Otherwise, traffic police may impose fines, as a locked license is equivalent to an invalid one. The vehicle owner needs to bring their driver's license to the issuing vehicle management office (or the nearest traffic police station) and request assistance from the officer at the violation handling window to inquire about the reason for the "lock." After addressing the issue accordingly, the license can be "unlocked." Situations where the Traffic Management 12123 app shows a locked status include: 1. Initial license acquisition: If it's the first time obtaining a driver's license and the license hasn't been collected from the vehicle management office, registering and logging into the Traffic Management 12123 app to check the license status may show it as locked. This is normal and doesn't require any action. 2. Pending update: Sometimes, even after collecting the driver's license, it may still show as locked. This requires waiting for the Traffic Management 12123 platform data to update before it displays as normal. 3. Lock due to violations: (1) For Class A or B driver's licenses, if there are violation records within the scoring cycle and the license holder fails to attend the annual review after the cycle ends, the license may show as locked. Attending relevant training sessions is necessary to unlock it. (2) If there are unresolved violations or traffic accidents, the license may also show as locked. Paying all fines and receiving corresponding penalties is required before the license can be released from suspension. (3) During periods when the license is legally canceled, detained, or revoked, it may also be locked. The holder must wait until the penalty period ends and then complete the necessary procedures to unlock it. (4) If the holder has no violations and it's not their first time obtaining a license, but the license status shows as locked upon checking, they should promptly consult the vehicle management office staff. It's possible that someone else has fraudulently used their license.

Reasons for Feeling Vibration in the Volkswagen Lamando at Idle Speed While Sitting Inside the Car

Reasons for feeling vibration in the Volkswagen Lamando at idle speed while sitting inside the car include excessive engine carbon buildup, among others. Below are detailed explanations for the vibration felt in the Volkswagen Lamando at idle speed while sitting inside the car: 1. Main Causes: The vibration felt in the Volkswagen Lamando at idle speed while sitting inside the car is primarily caused by eight main reasons: excessive engine carbon buildup, ignition system issues, unstable fuel pressure, failure of the coolant temperature sensor, improper air-fuel mixture, dirty air flow meter, EGR (Exhaust Gas Recirculation) problems, and poor fuel quality. 2. Solutions: Clean the fuel system and check the idle speed motor for carbon buildup, cleaning it if necessary; if the spark plugs have excessive carbon buildup, they can be removed and cleaned, or replaced if needed; for vibration issues caused by unstable fuel pressure, identify leaks in the fuel supply system and replace the corresponding components if necessary.
