Can the ETC on a car be stolen or hacked?

The ETC installed in cars is generally not susceptible to theft or hacking because the ETC requires inserting a dedicated ETC card, which can only communicate with authorized devices, such as ETC equipment at highway entrances and exits. Handheld devices cannot conduct transactions, making the possibility of theft or hacking after loss almost nonexistent. ETC Card Binding: ETC card binding can be divided into two scenarios: one is binding a credit card, and the other is binding a debit card. How ETC Works: Through the onboard electronic tag installed on the vehicle's windshield, dedicated short-range communication is established with the microwave antenna in the ETC lane at toll stations. This utilizes computer networking technology to perform backend settlement processing with banks, thereby achieving the purpose of allowing vehicles to pass through highway or bridge toll stations without stopping while still paying the required fees.

Should an Automatic Transmission Vehicle be Started in N Gear or P Gear?

Automatic transmission models control gear changes through the vehicle's onboard computer, where moving the gear shift lever generates signals. Therefore, it is more correct to start the vehicle in P gear. However, for automatic transmission vehicles, starting in either P gear or N gear is feasible, and there is no claim that starting in P gear harms the transmission. Below is an introduction to starting in different gears: 1. From the principle of the transmission, the gear lever does not directly change the transmission's gear. The movement of the gear lever only generates a signal, which is processed by the transmission control system (TCU), equivalent to a microcontroller, and then determines whether to shift gears based on pre-set programs. Thus, for actions that could potentially harm the transmission, the TCU can reduce their occurrence to some extent. 2. Therefore, as long as you do not stay in R gear after starting in P gear, it will not cause harm to the transmission. Hence, it is recommended to start the vehicle in P gear in daily life. Starting in P gear is more worry-free, fuel-efficient, and offers more benefits.

Can You Continue Driving After a Car Tire Blowout?

You should not continue driving after a car tire blowout. Since the tire loses its supporting force, the stability of the vehicle body is greatly affected, making it highly prone to traffic accidents. It is essential to promptly replace the spare tire or seek assistance. Below are specific repair methods: 1. Cold Patching: This method requires professional tire repair equipment and patches. Remove the damaged tire, clean the puncture site, apply a layer of cold patch glue on the inner side of the tire, and then stick the patch onto it. Cold patching is a common repair method, but it has a drawback: the hole on the tire tread remains, which may damage the tire's steel wires and fabric layers when driving on rough roads. 2. Hot Patching: After applying the patch, use a heating machine to bake the puncture site, ensuring the patch adheres better to the inner side of the tire. Pay attention to the heating time (avoid excessive duration), especially for thinner tires, as improper heating can easily damage the tire. 3. Mushroom Plug: Insert a mushroom-shaped rubber plug from the inside of the tire to the outside, completely sealing the puncture. Then, trim the exposed part and secure the inner part with special glue. This method not only provides external repair but also offers excellent internal repair effects.

What brand of engine oil does the Kicks use?

The original factory engine oil for the Kicks uses the 0W-20 Japan Genuine Super Fully Synthetic Engine Oil. If you want to change the oil during later maintenance, you can choose from brands such as Shell, Mobil, Castrol, and Great Wall. The official user manual recommends the 5W-30 SN/GF-5 and 5W-30 SM/GF-4 synthetic engine oils. Any oil that meets the officially recommended specifications can be used. The viscosity of engine oil changes with temperature, so special attention is needed to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The second number represents the kinematic viscosity at 100°C. A higher value means the oil can maintain its viscosity better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Kicks is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine for 30 seconds to allow the oil in the main oil passage to drain; Use a specialized wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add new oil through the engine valve cover filler port, usually filling about three-quarters of the bottle; Start the engine and let it run for 5 minutes, then check for leaks around the drain plug and oil filter. If leaks are found, perform necessary repairs; After stopping the engine, pull out the dipstick to check that the oil level is within the standard range.

What documents should I bring when driving out?

When driving out, you should bring the following documents: 1. Driver's license: The permitted vehicle types on the license must match the vehicle you are driving. 2. Vehicle registration certificate: Carry the registration certificate that corresponds to the license plate of the vehicle you are driving. The registration certificate must not be lent, altered, or forged. 3. The driver's ID card. 4. License plate (or temporary plate or replacement plate certificate): The license plate should be properly and visibly displayed with clear characters, matching the vehicle type and number on the registration certificate. Expired or invalid temporary plates must not be used. 5. Road maintenance fee certificate: Carry a valid unified road maintenance fee payment certificate, ensuring the vehicle type, license plate, unit, and date on the certificate are correct. 6. Insured vehicles must carry the insurance policy. 7. If driving a commercial vehicle, you also need to carry the road transport practitioner qualification certificate.

What is the normal pressure of car air conditioning refrigerant?

Under the condition of compressor speed at 1500~2000 rpm, the normal pressure of car air conditioning refrigerant is approximately 1.5~2.0 MPa for high pressure (discharge pressure) and 0.15~0.35 MPa for low pressure (suction pressure). Extended information is as follows: 1. Introduction to normal car air conditioning pressure: Normal high pressure should be 1.3-1.7 MPa (13-17 kg/cm2 or 190-250 Lbf/in2); normal low pressure should be between 0.15-0.25 MPa (1.5-2.5 kg/cm2 or 20-35 Lbf/in2). 2. Introduction to normal car air conditioning pressure at idle: At idle speed, if the ambient temperature is high, such as under direct sunlight in summer, the high pressure may be slightly higher, up to about 2.5~2.8 MPa, but generally it will not exceed 3.1 MPa, otherwise the pressure switch will be protected. If the low pressure is higher or lower than this range, it indicates that the expansion valve adjustment is abnormal. If the compressor has problems, it is not within this category.
