ETC Activation Method After Removal: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth is on". If "Tag Invalid" appears after two insertions without the electronic tag attached, this is normal and does not affect activation. Alternatively, you can directly press the button on the top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile app (usually a download QR code is provided on the electronic tag), and enter the device activation interface. Click on device connection and wait patiently for the "Connection Successful" prompt. After successful connection, upload a photo of the vehicle's front to complete activation. ETC Installation Process: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU; a red light will briefly illuminate, and the OLED screen will display "Tag Invalid" and "Please Insert Card", indicating the device is functioning normally. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then peel off the OBU's adhesive backing and attach it to the installation position. Press firmly with your hand for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device.

After removing the ETC device and reactivating it, the first step is to confirm that the device is not damaged. After experiencing this a few times, I’ve developed the habit of checking whether the installation position is secure first. Reattach it to the center of the windshield, leaving space for solar charging and ensuring it doesn’t block the signal. Next, open the ETC partner app or official website, log into your account, and enter the device management section. Input your license plate number and the serial number on the back of the device, then take a photo of the installation and upload it for submission. The backend usually processes it quickly, but once I entered the wrong number of digits for my license plate, causing the activation to fail and delaying my highway trip. I recommend testing the reactivation at a nearby toll station afterward to avoid any issues that might affect driving safety. The whole process is quite simple—just be careful when filling in the details, and it can be done in minutes.

How many minutes must be taken for rest to avoid fatigued driving?

If a driver operates a vehicle continuously for more than 4 hours without stopping to rest or takes a break of less than 20 minutes, electronic surveillance will identify these fatigued drivers. Traffic police departments will legally require the driver to stop and rest, issuing a warning. In severe cases, penalty points may also be deducted according to the law. Precautions for driving on highways are as follows: 1. Safety check: Check for potential hazards before getting in the car. Before driving on the highway, inspect the vehicle for any safety risks. 2. Wear seat belts: Always wear seat belts on the highway, including the driver, front passenger, and rear seats. Avoid placing unsecured items in the car. 3. Stay in one lane: Avoid frequent lane changes on the highway, switching between the passing lane and the travel lane, and never make sudden unannounced decelerations or stops in the travel lane. While driving, do not drive side by side with other vehicles, avoid prolonged driving in the passing lane, and never attempt to overtake from the emergency lane. Additionally, prepare for lane changes in advance when exiting the highway to avoid missing the exit.

What does MT mean?

In automobiles, MT stands for Manual Transmission, also known as manual gearbox. It involves manually shifting the gear lever to change the gear meshing positions inside the transmission, altering the gear ratio to achieve the purpose of shifting. A manual transmission is a type of gearbox used to modify the speed and torque transmitted from the engine to the driving wheels. Under various driving conditions such as starting from a standstill, climbing hills, turning corners, and accelerating, it enables the vehicle to achieve different levels of traction and speed while keeping the engine operating within a more favorable range. Functions of a manual transmission: Changing the gear ratio to expand the range of torque and speed variations at the driving wheels, adapting to frequently changing driving conditions. While maintaining the engine's rotational direction, reverse gear is used to enable the vehicle to move backward. With the engine still running, neutral gear can be used to interrupt power transmission, which is beneficial for engine startup, warm-up, idling, and facilitates gear shifting, coasting, or temporary parking. The transmission can also divert engine power to drive other mechanisms, such as the winch on certain vehicles or the oil pump on dump trucks.

Which is more important, front or rear tires for a car?

Whether front or rear tires are more important for a car mainly depends on whether the car is front-wheel drive or rear-wheel drive. Front-wheel drive means the front tires are more important, while rear-wheel drive means the rear tires are more important. Rear-wheel drive vehicles: For rear-wheel drive vehicles, the rear tires are more important when replacing tires. For rear-wheel drive cars, new tires should be installed at the rear because the rear tires of such vehicles are prone to slipping, and the power is also concentrated on the rear wheels. When the rear tires are severely worn, their grip becomes very weak, making the car more likely to roll over during driving. On wet or slippery roads or during sharp turns, accidents are more likely to occur. Front-wheel drive vehicles: For front-wheel drive cars, new tires should be installed at the front because the front tires of such vehicles require higher grip. During sudden braking, the car's center of gravity shifts forward. If the front tires lack sufficient grip, accidents are more likely to happen. Therefore, new tires for front-wheel drive cars should be replaced at the front.

What lights to use when passing under an arch bridge at night?

When passing under an arch bridge at night, alternately use high and low beams no less than 2 times. Below is a detailed introduction to light usage methods: 1. Night driving: When turning at intersections at night, use low beams. When driving on low-visibility roads at night, turn on high beams. When passing sharp curves at night, alternately use high and low beams no less than 2 times. When passing slopes at night, alternately use high and low beams no less than 2 times. When passing under arch bridges at night, alternately use high and low beams no less than 2 times. When passing crosswalks at night, alternately use high and low beams no less than 2 times. When passing intersections without traffic lights at night, alternately use high and low beams no less than 2 times. When overtaking at night, first turn on the left turn signal, then alternately use high and low beams no less than 2 times, then turn on the right turn signal. When meeting other vehicles at night, turn on low beams. 2. Driving in fog: Turn on width markers, front/rear fog lights, and hazard lights. 3. In case of malfunction: Turn off headlight assembly and turn on width markers and hazard lights.

Is Battery Drain Covered Under Warranty?

Whether battery drain is covered under warranty requires a comprehensive analysis based on the specific purchase time of the battery. Daily maintenance of the battery is essential. Below are some key points regarding battery maintenance: Proper Driving Habits: If the vehicle fails to start, wait for about 5 seconds before attempting to restart. Avoid repeated starting attempts, as continuous cranking can lead to excessive battery discharge, damaging its lifespan. Car Battery Maintenance: When the battery voltage is low and the lights appear dim or the engine struggles to start, it is advisable to charge the battery externally. Regularly check the battery connections to ensure they are secure. All live terminals must maintain good contact to prevent sparking, which could cause the battery to explode. Any oxides or sulfates on the battery terminals should be thoroughly cleaned off.
