Which Gear is Reverse?

In vehicles, the letter R represents the reverse gear, whether it's a manual transmission or an automatic transmission. Automatic transmissions typically have four main gears: P, R, N, and D, which stand for Park, Reverse, Neutral, and Drive, respectively. Some automatic transmissions also include an S gear and an L gear, where S stands for Sport mode and L stands for Low gear. The reverse gear, fully known as the Reverse Driving Gear, is labeled as R on the gear console. Its purpose is to enable the vehicle to move backward, serving as a special driving gear. When the driver shifts the gear lever to the reverse position, the direction of the power input from the engine remains unchanged, while the internal reverse output gear of the transmission engages with the output shaft, causing the output shaft to rotate in the opposite direction. This, in turn, drives the wheels to rotate in reverse for backing up the vehicle.

Can the installed ETC card be removed?

The ETC card can be removed, but the ETC device will not function without it. According to the "Rules for the Use of Non-Stop Rapid Passage Systems," the ETC card must be inserted into the OBU device for normal operation; otherwise, user information cannot be read. If the card is removed, you can use the manual lane and have the staff swipe the card for you. When the ETC card is inserted into the OBU device, a prompt sound will indicate that the device is activated. Without the card, the device remains in a dormant state and cannot recognize vehicle information at toll stations, so removing the card disables the ETC functionality. ETC is an electronic toll collection system, also known as an automatic road toll system. It is specifically designed for toll roads and is commonly used on highways, toll bridges or tunnels, and certain urban sections to alleviate traffic congestion. ETC Deduction Principles: Highways have one or more ETC lanes. Communication between the vehicle-mounted electronic tag on the windshield and the microwave antenna in the ETC lane enables toll payments without stopping at toll booths. This is achieved through computer networking technology and backend bank settlements, operating on a "pass first, deduct later" principle. Benefits of Installing ETC: Time-saving: Eliminates the need to queue and wait. Green and eco-friendly: Reduces noise and exhaust emissions by avoiding idling at toll booths. Cost-saving: Lowers wear and fuel consumption by reducing frequent starts and stops. Users also enjoy a 5% discount on toll fees. Improved efficiency: ETC lanes theoretically increase throughput by 2-3 times, making traditional ETC faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council's "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" explicitly states the goal of "achieving interoperability of transportation cards in key urban clusters by 2020 and significantly increasing the adoption rate of ETC in vehicles." It also sets a target of "50% ETC usage rate for road passenger vehicles by 2020." Future possibilities: Beyond improving the convenience of ETC installation and usage rates for passenger vehicles, future efforts will promote ETC adoption for trucks and explore deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation developments. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage.

Should You Press the Brake When Starting a Manual Transmission Car?

When to press the brake when starting a manual transmission car: On flat ground, it's not necessary, but when starting on a slope, it's best to press the brake: 1. Adjust the seat before starting the car to ensure your feet can firmly and comfortably press the clutch, brake, and accelerator; 2. For a manual transmission car, shift into first gear when starting, press the clutch all the way down, and place your right foot on the accelerator ready to go; 3. When starting, slowly lift the clutch with your left foot to about halfway, and when you feel the car start to shake, release the handbrake promptly, then gently tap the accelerator. As the car starts to move forward, slowly release the clutch and add a bit more accelerator to successfully start; 4. Pay special attention when starting on a slope. If the handbrake is released too quickly and the clutch isn't lifted enough, the car can easily roll back.
