Does the ETC card have a front and back side?

1 Answers

ETC cards have a front and back side. The method to insert the card into the ETC device (commonly known as OBU or electronic tag) is as follows: Insert the card with the front side facing the driver, the back side facing the windshield, and the chip part inserted into the OBU device. Specific installation requirements for ETC: 1. The height should not be lower than 1.2 meters or higher than 2.5 meters; 2. The installation angle should be between 30 and 90 degrees. ETC works through dedicated short-range communication between the vehicle-mounted electronic tag installed on the vehicle's windshield and the microwave antenna on the ETC lane at toll stations. It uses computer networking technology to perform background settlement processing with banks, thereby achieving the purpose of vehicles passing through highway or bridge toll stations without stopping to pay the fees.

How to reset the tire pressure light on Volkswagen Tiguan?

Methods to reset the tire pressure light on Volkswagen Tiguan: First, turn on the ignition, then press and hold the tire pressure monitoring reset button. After hearing a "beep" sound, release the button. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset. There are three commonly used methods for tire pressure monitoring: Direct tire pressure monitoring: The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure the tire pressure. It uses wireless transmitters to send pressure information from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. Indirect tire pressure monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above, equipping direct sensors in two diagonally opposite tires and incorporating a 4-wheel indirect system.

What Causes the Hissing Sound When Opening the Fuel Tank Cap?

It is mainly caused by the pressure difference between the inside and outside of the fuel tank. The specific reasons are as follows: 1. The charcoal canister in the fuel tank helps balance the internal and external pressure. The hissing sound occurs due to the pressure difference between the inside and outside of the fuel tank. The charcoal canister's function is to maintain this balance. If the charcoal canister malfunctions, the fuel tank cap cannot release pressure, leading to an imbalance between internal and external pressure. This results in the hissing sound when opening the fuel tank cap. 2. The hissing sound is more common in summer because higher temperatures cause the gasoline to expand. Since the vehicle's space is fixed, the sealed gasoline vapors create pressure inside the tank, which is higher than the external pressure. Therefore, a sound is heard when opening the fuel tank cap.

Which BMW Model Corresponds to the Blade-Style Key?

BMW's blade-style key corresponds to the BMW 530Li. Although the blade key isn't as high-tech as the LCD display key, its tactile feel and design are irresistible, especially the M tricolor stripe on the side—an absolute emblem of faith for BMW enthusiasts. Here are the details about the BMW 530Li: 1. The 3.0-liter inline-six engine provides ample power reserves for the 530Li, with a maximum output of 190 kW/258 hp and a peak torque of 300 Nm, matching the data of the standard 530i. 2. Equipped with BMW's Dynamic Stability Control (DSC), the 530Li reduces risks like oversteer or understeer. DSC stabilizes the vehicle by reducing engine power or applying brakes to individual wheels. 3. The front section under the seat thigh can be adjusted forward and backward, offering more comfortable leg support during long-distance driving.

How to Remove the Front Bumper of a Kia K2?

Steps to remove the front bumper of a Kia K2: 1. Open the hood. 2. Loosen the screws between the headlights. 3. Unscrew the screws on the wheel arch panels (you can turn the steering wheel left or right to facilitate this step). 4. Unclip the fasteners on the front wheels (there are also fasteners at the bottom of the front bumper; use a flashlight to locate the screw positions and avoid pulling too hard to prevent breaking the clips). Below is some related knowledge about bumpers: 1. Bumpers serve functions such as safety protection, vehicle decoration, and improving the vehicle's aerodynamic characteristics. From a safety perspective, they help absorb impact during low-speed collisions, protecting the front and rear body of the car. In accidents involving pedestrians, they can also provide some protection. 2. Aesthetically, bumpers enhance the vehicle's appearance and are an important decorative component. Additionally, they contribute to aerodynamics. Moreover, to reduce passenger injury during side collisions, door bumpers are often installed in cars to reinforce the doors' impact resistance.

Should I Replace My Car Battery If It's Dead?

If the battery is not damaged, replacement is unnecessary. Below are methods to check if the battery is faulty: 1. Check the battery voltage. A normal battery voltage is 12V. After starting the generator, the voltage should rise to 13-14V. If the voltage is below 12V when the vehicle is off or below 13V after starting, the battery may have issues. 2. Check the battery's usage time. Currently, the most commonly used car batteries are lead-acid maintenance-free batteries, with a lifespan of around 2 years. With proper maintenance, they can last 3-4 years. Start-stop vehicle-specific batteries have a lifespan of 4-6 years. If the battery exceeds these timeframes, replacement should be considered. 3. Use a car emergency jump starter to power the vehicle. After starting, let the engine run for 30 minutes, typically maintaining around 1500 RPM. Charging for 30 minutes and leaving it overnight should allow the car to start the next day, indicating the battery is still functional. Most car insurance policies now include 2 free roadside assistance services, so you can simply call for help.
