Correct method to insert ETC card: Carefully observe the ETC card to locate the arrow mark, then insert it into the OBU device following the arrow's direction. The OBU device refers to the electronic tag equipment provided by merchants when applying for ETC service. After inserting the ETC card into the OBU device, place the ETC unit on the vehicle's front windshield storage compartment. ETC (Electronic Toll Collection) is a fully automated electronic toll system and one of the service functions of intelligent transportation systems. It is particularly suitable for highways or busy bridge/tunnel environments, with dedicated ETC lanes available at highway toll stations.

I've been using ETC myself for several years and always knew proper installation is crucial. The simplest way is to find the upper area on the inside of the windshield, like near the rearview mirror, not too close to the edge nor right in the middle blocking the view. Before sticking, carefully wipe the area clean with a cloth - absolutely no dust or moisture, otherwise the adhesive won't hold. Peel off the device's backing, align it and press firmly for about ten seconds to secure it. Remember not to install it on dotted or tinted glass areas where there's more metal causing signal interference, which may lead to failure at highway toll gates. The solar panel must face outward to ensure charging and avoid power loss. Test it immediately after installation by entering an ETC lane to see if the barrier lifts normally, saving you a wasted trip. Common mistakes include installing too low where the sun visor may loosen it, or moving it around causing adhesive failure. Proper installation saves hassle and money - just regular surface dust cleaning suffices. In short, once fixed in position, leave it untouched for smoother travels.

What is the difference between full-time four-wheel drive and on-demand four-wheel drive in sedans?

The difference between full-time four-wheel drive and on-demand four-wheel drive in sedans lies in the driving method: the full-time four-wheel drive system uses four-wheel drive under all conditions; on-demand four-wheel drive is a more intelligent four-wheel drive system. Full-time four-wheel drive distributes driving force to all four tires through a flexibly connected central differential, along with independent front and rear axle differentials. Unlike purely mechanical differential locks, the differential in full-time four-wheel drive can be either a viscous coupling type or a multi-clutch type, but both allow for a speed difference between the front and rear wheels, as well as between the left and right wheels. On-demand four-wheel drive only switches to four-wheel drive when necessary and remains in two-wheel drive mode under other conditions. The system automatically switches between two-wheel drive and four-wheel drive modes based on the driving conditions, without requiring manual intervention.

Where is the rearview mirror heating switch on the MG6?

The rearview mirror heating switch on the MG6 is located on the center console. There is a square-shaped icon next to the air volume control with several vertical lines on it—this is the button. The rearview mirror heating function is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rainwater or fog, eliminating the need for the driver to manually wipe the mirrors frequently and thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is needed, as the driver's side has a dedicated adjustment button. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature (usually between 35-60°C) within a few minutes. The heat is then distributed across the left and right rearview mirrors. As the temperature rises, water droplets on the mirror surface gradually shrink, and fog slowly dissipates, effectively clearing the mirror of frost and condensation. However, in heavy rain, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The heating function works by using electric heating wires embedded in the rearview mirror, which consume a significant amount of power. Ensure the vehicle is running when using this feature to avoid draining the car battery, which could prevent the engine from starting. Other methods for defogging rearview mirrors include: Opening windows slightly: Creating a gap in the side windows allows air convection between the interior and exterior, reducing temperature differences and gradually eliminating fog. Adjusting the car's air conditioning to the appropriate setting: Using warm air from the AC can also help defog the mirrors.

Are Temporary License Plates Subject to Traffic Restrictions?

New vehicles with temporary license plates are subject to traffic restrictions. After purchasing a new car, the vehicle management office will issue a temporary license plate for the vehicle to drive on the road. After the implementation of tail number restrictions, motor vehicles with temporary license plates and those with license plate tail numbers as English letters will both be subject to traffic management. The paper motor vehicle license plate that allows temporary road use, also known as a temporary driving license plate, refers to a temporary vehicle driving certificate issued by the public security vehicle management department before the new vehicle is officially registered. The validity period of a temporary license plate generally does not exceed thirty days, and there are four types: temporary license plates within administrative districts, temporary license plates across administrative districts, temporary license plates for testing, and temporary license plates for special-type motor vehicles.

Do you need a driver's license to drive a new energy vehicle?

Driving a new energy vehicle requires a driver's license. As a type of motor vehicle, operating a new energy vehicle also necessitates a driver's license. New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as their power source (or use conventional vehicle fuels with new types of on-board power devices), integrating advanced technologies in vehicle power control and drive systems to form vehicles with advanced technical principles, new technologies, and novel structures. New energy vehicles include four main types: Hybrid Electric Vehicles (HEV), Battery Electric Vehicles (BEV, including solar-powered vehicles), Fuel Cell Electric Vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices). The promotion of new energy vehicles aims to address environmental protection and oil crisis needs, reducing or abandoning the current mainstream models that burn traditional gasoline or diesel to drive internal combustion engines.

What are the techniques for parking and shifting gears?

Techniques for parking and shifting gears: 1. Wait for the car to come to a complete stop, then shift into N (Neutral) gear; 2. Engage the handbrake and close the doors and windows; 3. Turn off the engine, shift into P (Park) gear, and exit the vehicle. Gear shifting refers to the transmission, which is used to change the torque and speed of the engine crankshaft to meet the different requirements of driving wheels for traction and speed under various driving conditions such as starting, accelerating, driving, and overcoming road obstacles. Automatic transmission usually refers to the automatic gear-shifting mechanism of a car. While driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine speed and load, replacing the driver's subjective judgment and gear-shifting operations. A typical automatic transmission car has six gear positions, from top to bottom: P (Park), R (Reverse), N (Neutral), D (Drive), S (Sport), and L (Low).
