Does Manual Transmission Have Jerking?

What Causes Parking Brake Failure Preventing Ignition?

Parking brake failure preventing engine start is typically caused by a malfunctioning brake light switch, which prevents the ECU from receiving the proper ignition signal. Replacing the brake light switch can resolve this issue. This problem commonly occurs in automatic transmission models, as the brake light switch also serves the function of providing power-on signal feedback for engine start. The parking brake, commonly known as the handbrake, functions to provide resistance when parking, preventing the vehicle from rolling. The correct usage method of the parking brake is as follows: 1. To engage the parking brake, firmly depress the brake pedal and fully pull up the parking brake lever. To release the parking brake, depress the brake pedal, slightly lift the parking brake lever, press the button on the handle with your thumb, then lower the lever to its original position. 2. When parking on an incline, if you shift into P position before applying the parking brake, the vehicle's weight may make it difficult to shift out of P when preparing to drive. 3. When preparing to drive, always shift the gear lever out of P position before releasing the parking brake.

How to Check if the Car Radiator Coolant is Low

Method to check the car radiator coolant level: Inspect the positions of the MIN and MAX markings on the car radiator. The coolant level should be maintained between the MAX and MIN marks for optimal operation, indicating neither too much nor too little. If the level is below MIN, it indicates insufficient coolant, and it needs to be replenished. When adding coolant, it is recommended to use specialized coolant. In emergency situations, distilled water can be used temporarily. However, before winter arrives, any coolant mixed with distilled water must be completely replaced. Tap water or other water sources should be avoided as the minerals and impurities they contain can form scale inside the cooling system under prolonged high temperatures and may also cause rust in the radiator and pipes, obstructing coolant flow. Therefore, these should only be used as a last resort.

Should the Vehicle Stability System Be Kept On Normally?

It is recommended to keep the Vehicle Stability System (VSS) normally activated. The Electronic Stability Program (ESP) is a general term for systems or programs designed to enhance vehicle handling performance while effectively preventing loss of control when the vehicle reaches its dynamic limits. The electronic stability program can improve vehicle safety and handling. The ESP system consists of a control unit and sensors such as steering sensors, wheel sensors, skid sensors, and lateral acceleration sensors. The vehicle stability system can prevent dangers when the car is turning, but it is advised not to activate the stability system under the following circumstances: 1. If pursuing vehicle handling sensations, it is not recommended to activate it, as it becomes difficult to perform maneuvers like drifting or oversteering when the system is on; 2. During vehicle inspection on the testing line, the stability system should be turned off. During the test, most front-wheel-drive vehicles have only two wheels moving, and the system might interpret this as wheel slip and intervene, which could affect the inspection results.

What is the normal value of car water temperature?

Car water temperature gauge at 90 degrees is the normal value. After the vehicle starts, the antifreeze temperature rises rapidly. When the pointer reaches the central position, the heat exchange balance is achieved and the antifreeze temperature no longer rises. Generally, it is optimal to start driving when the temperature reaches the middle position. The engine water temperature gauge uses a physical or virtual dial pointer display. A few vehicles do not have a dashboard and only display a warning indicator when the temperature is too high. Whether it is a physical or virtual water temperature gauge, the pointer orientation is generally similar, usually using a dial ranging from 60 to 120 degrees. Generally, cooling system failures mainly include fluid leakage, insufficient coolant, radiator fan failure, and circulation pump failure.

What does 'off' mean in a car?

There are many buttons with 'off' in a car. If there is a circle with 'off' below it, then this button is the switch for turning off the car's auto start-stop function. If a button has a small car with two curves behind it and 'off' written below the curves, then this button is the switch for turning off the ESP (Electronic Stability Program) electronic body stability system. After pressing the ESP off switch, an ESP off icon will appear on the dashboard to remind the driver that ESP is now turned off. For all vehicles equipped with ESP, the system is turned on by default after starting the car. The ESP off switch is rarely used during daily driving and is only needed in specific situations, such as when the vehicle is stuck in mud or sand during off-road driving.

What are the techniques for smooth downshifting without jerking?

Techniques for smooth downshifting without jerking: 1. Perform gear shifting operations promptly without excessive delays, and release the clutch slightly slower; 2. When upshifting, ease off the throttle, and when downshifting, apply a slight amount of throttle to avoid noticeable jerking. Additionally, practice more to become familiar with the relationship between each gear and speed, and the operation will become smooth without jerking. Basic principles of gear shifting (gear matching): 1. Match the speed with the appropriate gear: The suitable speed range for each gear spans from the minimum to the maximum speed for that gear. Avoid prolonged use of the minimum or maximum speed for any gear whenever possible; 2. Gear shifting (upshifting and downshifting): In principle, as long as the speed falls within the gear's range, shifting is possible. The choice of gear should consider vehicle speed, power performance, and fuel efficiency; 3. Lugging: Speeds below the minimum for a gear are generally referred to as lugging. Lugging can cause the vehicle to lose power and jerk forward or backward, and in severe cases, it may lead to engine stalling.
