The 'a' next to the electronic handbrake stands for the auto-hold system, a technological application that enables automatic handbrake functionality while the car is in operation. The auto-hold system allows drivers to avoid prolonged braking when the vehicle is stationary and prevents unnecessary rolling when the automatic electronic parking brake is engaged. The principle of auto-hold is that the vehicle's ECU can automatically measure data such as wheel torque and the vehicle's levelness to determine if there is a tendency for the car to roll. If such a tendency is detected, the ECU applies an appropriate braking force to the wheels to keep the vehicle stationary. When starting off, pressing the accelerator pedal will automatically deactivate the auto-hold, allowing the vehicle to move smoothly.

The 'A' button next to the electronic parking brake is actually the indicator for the Auto Hold function, which means automatic brake hold. When you stop at a red light or in traffic, once you release the brake pedal, the system automatically locks the wheels to prevent the car from rolling. When you're ready to start, pressing the accelerator will automatically release the brake, saving you from having to keep your foot on the brake pedal. When I first started driving, I found it confusing too, but after using it, I realized it helps prevent rollback accidents, especially on uphill roads. However, it's not a cure-all. For example, on slippery surfaces or steep slopes, you still need to pay attention to your speed and the terrain, as sudden release could cause skidding. Overall, this function simplifies driving operations, enhances convenience and safety. I recommend new drivers try it out more to familiarize themselves with its activation and response time, as developing good habits makes a big difference.

The A button refers to the Auto Hold system, which I frequently use to relieve my feet, especially during traffic jams or when waiting at traffic lights. Once activated, the vehicle automatically locks the brakes, allowing you to release your foot without worrying about movement. It disengages automatically when you press the accelerator to start, making it truly convenient and effortless. I've also noticed that it helps reduce brake wear because the system intelligently controls pressure, avoiding excessive wear caused by frequent pedal use. However, it's important to gently press the accelerator when starting on icy or muddy roads to prevent slipping risks. Overall, this feature enhances driving comfort, acting like a small assistant to ensure vehicle stability, and is worth utilizing properly by drivers to improve driving efficiency and safety.

In my driving experience, the 'A' next to the electronic parking brake stands for Auto Hold. After pressing it, the car automatically holds still when stopping, and it releases when you press the accelerator to start, which is especially convenient during rush hour. After using it frequently, I've found it suits urban driving conditions well, but remember to be cautious when starting on slopes—apply the accelerator gently to avoid losing control. This feature is thoughtfully designed to make driving easier.

Where is the handbrake of the Bora?

The handbrake of the Bora is located near the center console. Introduction to the handbrake: The professional term for the handbrake is auxiliary brake. Unlike the principle of the main brake, it uses a steel cable connected to the rear brake shoes to brake the vehicle. Long-term use of the handbrake can cause plastic deformation of the steel cable. Since this deformation is irreversible, prolonged use will reduce its effectiveness, and the handbrake's travel will also increase. Components of the handbrake: It consists of a brake lever, cable, brake mechanism, and return spring, acting on the drive shaft or rear wheel brakes to achieve vehicle stability. Electronic handbrake working principle: It is activated or deactivated via a button, and the electronic handbrake can be engaged under any vehicle condition.

Does filling up the gas tank in summer affect the car?

Filling up the gas tank in summer does affect the car. Here are the specific details: 1. Driving safety: The car's fuel tank has a vent hole at the top. If the tank is filled to the brim, gasoline can easily overflow from the vent hole. 2. Tank deformation: The fuel tank has a fixed capacity, and leaving some space prevents gasoline expansion. If the tank is overfilled, gasoline will expand due to heat from the sun, which can deform the tank. 3. Vehicle performance: More gasoline increases the vehicle's weight, requiring the engine to consume more fuel to move the car. 4. Other effects: It can severely reduce the performance of the carbon canister, leading to engine shaking, increased fuel consumption, faster gasoline evaporation, and gasoline odors entering the cabin, which can harm health with long-term exposure.
