Here are the differences between two-wheel drive and four-wheel drive vehicles: 1. Different driving methods: Two-wheel drive means that only two wheels are the driving wheels connected to the vehicle's power system. Four-wheel drive refers to the form in which the vehicle maintains all four wheels as driving wheels throughout the entire driving process. 2. Different fuel consumption: The four-wheel drive mode can provide better off-road and handling performance at any time, but it cannot adjust torque distribution according to road conditions and has higher fuel consumption. 3. Different numbers of differentials: (1) Two-wheel drive: The vehicle differential is a mechanism that allows the left and right (or front and rear) driving wheels to rotate at different speeds. (2) Four-wheel drive: In four-wheel drive, to drive all four wheels, all wheels must be connected. If the four wheels are mechanically connected together, a central differential is needed to adjust the speed difference between the front and rear wheels.

What does an ISOFIX interface look like?

The ISOFIX interface has the word 'ISOFIX' on it, and its icon resembles a person sitting on a seat. 1. Description of the ISOFIX interface: There are two interfaces at the connection between the car seat backrest and the seat cushion, which are the ISOFIX interfaces. This is a rigid connection method designed to prevent seat flipping during a collision. Some seats also come with support legs and other anti-flip devices in addition to the ISOFIX interfaces. 2. Function: The ISOFIX interface can securely connect a child car safety seat to the car, providing a simpler and safer way to install the car seat. Installing a seat using ISOFIX is easier than using a seatbelt and can effectively reduce the risk of incorrect installation, significantly lowering the probability of installation errors. 3. Fixation methods: In addition to the ISOFIX interface fixation method, there are also the LATCH fixation method (American standard) and the seatbelt fixation method. The location of the LATCH interface varies depending on the vehicle model. For sedans, it is usually located behind the rear seat headrest, while for hatchbacks, it is typically on the back of the rear seat. The LATCH fixation method is also simple, adding hooks to the ISOFIX method. After fixing with the ISOFIX method, the hooks are secured. In a true sense, the most secure and safest installation is achieved by combining the LATCH interface with the ISOFIX interface.

How to Check If You Have an ETC

Vehicle owners can bring their ID card, vehicle license, and other documents to an ETC service outlet and consult the staff to check whether their vehicle has an ETC. Here are some related details: 1. How to check if the ETC is activated: Simply insert the ETC card into the ETC electronic tag to check. If the ETC card balance is displayed, it means activation is successful. Additionally, when passing through an ETC lane, hearing a "beep" sound indicates successful deduction, the barrier will automatically rise, and the ETC is functioning normally. 2. How to determine if the ETC is working properly: (1) For a newly received ETC electronic tag (OBU device), when pressing the anti-tamper switch on the back, the red light will briefly turn on, and the screen will display messages like "Tag Invalid" or "Please Insert Card," indicating the device is normal and does not affect activation. (2) For an already activated ETC device, when inserting the ETC card, the corresponding vehicle information or account balance will be displayed, confirming the device is functioning properly. (3) If the screen does not display anything after inserting the card, or the ETC light does not turn on (remaining black), and the device is powered on, it may indicate the device is out of battery or damaged. Although ETC electronic tags are powered by solar panels, they also have an internal battery with a lifespan of about 3 years. In such cases, the device should be taken to an ETC service outlet or highway service center for inspection and reactivation to resume normal use.
