R stands for Reverse gear, which is used when backing up. Here is more information about the R gear in automatic transmission: 1. Unlike manual transmission vehicles, automatic transmission cars cannot use the clutch slip technique, so special attention should be paid to the control of the accelerator pedal when reversing. 2. Usually, you need to press the safety button on the shift lever to move it to the "R" position. 3. It is important to note: Never force the shift lever into the "R" position when the vehicle is not completely stopped, as this can cause serious damage to the transmission. 4. Whether it's a manual or automatic transmission, the R gear always means reverse gear.

Is Rusty Brake Pads a Sign of a New Car?

It is normal for new car brake pads to have rust, and rust on the vehicle's brake discs is a common phenomenon that does not affect the normal use of the car. Moreover, it is not a standard for checking whether a vehicle is new. However, car owners should regularly inspect the condition of the brake pads and replace them in a timely manner. Below are some considerations when purchasing brake pads: 1. Four Key Points to Check: (1) Check the friction coefficient. The friction coefficient determines the basic braking torque of the brake pads. If it is too high, it can cause wheel lock-up during braking, loss of directional control, and overheating of the pads. If it is too low, the braking distance may be excessively long. (2) Check safety. Brake pads generate instantaneous high temperatures during braking, especially during high-speed driving or emergency braking. Under high temperatures, the friction coefficient of the pads may decrease. (3) Check comfort, including braking feel, noise, dust, smoke, and odors, which are direct reflections of friction performance. (4) Check lifespan. Typically, brake pads can ensure a service life of 30,000 kilometers. 2. Two Choices: (1) Choose automotive brake pads produced by reputable manufacturers, with license numbers, specified friction coefficients, and compliance with standards. The packaging should include a certificate of conformity, production batch number, and production date. (2) Choose to have them installed by professionals at specialized repair shops.

Does a Malfunctioning Traffic Light Count as Running a Red Light?

Running a red light due to a malfunctioning traffic signal does not count as a violation. If the violation was indeed caused by objective reasons such as a traffic light failure, you can file an appeal for reconsideration. Criteria for determining running a red light: Electronic surveillance cameras capture three photos as evidence for running a red light: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels crossing the opposite stop line. Only when all three photos are present will it be considered running a red light. How to avoid running a red light while driving: Follow the arrow signal if available; otherwise, observe the circular light. When the red light is on, the front of the vehicle must not cross the stop line. When the yellow light is on, the front of the vehicle must not cross the stop line. When the green light starts flashing, if you are close and moving fast, you should proceed, as stopping might be difficult and could result in crossing the stop line. If you are far away, moving slowly, or the intersection is congested, you should stop. When driving in the city, develop the habit of looking for traffic lights whenever you see a crosswalk or stop line at an intersection.

What is cordial tire?

cordial is Cheng Yuan tire, which is a motorcycle tire produced by Sichuan Yuanxing Rubber Company. The company was established in 1996 and partnered with Dachangjiang Group in 2008 to create the Cheng Yuan branch, launching the premium tire brand Cheng Yuan. There are two types of motorcycle tires: bias-ply tires and radial tires. Most cruiser motorcycles use bias-ply tires, while most sport motorcycles use radial tires. The structural design of radial tires allows them to carry heavier loads, making them suitable for cruiser motorcycles that need to bear more weight from passengers or luggage. Bias-ply tires better meet the suspension and cornering performance requirements of cruiser motorcycles.

What do the English letters R, P, D on the car gear shift mean?

The English letters on the car gear shift represent: R stands for Rear (reverse gear), P stands for Park (parking gear), and D stands for Drive (driving gear). The functions of R, P, and D gears are respectively: 1. The R gear is used when reversing the vehicle. When shifting into reverse, it's important to stabilize the speed first and avoid suddenly shifting into reverse while accelerating forward. 2. The P gear is engaged when reaching the destination and turning off the engine for parking. At this time, both the wheels and transmission are in a locked state, preventing the vehicle from rolling downhill. 3. The D gear is engaged when driving forward, after which you can press the accelerator. Other gear positions on a car mean: N stands for Neutral, S stands for Sport mode, L stands for Low gear, and M stands for Manual mode in an automatic transmission.
